How to extend laptop battery life

Disable unnecessary options or devices

When not using, unplug your mouse, external drive, Bluetooth, Wi-Fi, and other devices that consume power. Look in the control panel and find what you can turn off.

Turn on hibernation

There are two differences in Windows: sleep and hibernation. If you leave your computer for a few hours, it is best to put it to sleep. Hibernation mode allows you to save all settings and open documents to the hard disk and completely cuts off the power supply. When you turn on the computer, the content is restored. You do not need to reopen the documents you left off. This will be done automatically.

It is worth using hibernation if you leave the laptop for a very long time. In principle, there is no time limit. During hibernation, no electricity is consumed at all. When waking up from hibernation, the laptop takes much longer to wake up than it does from sleep. Sleep mode consumes about 5-7% of the battery capacity per day. The hibernation mode also loads the hard disk very heavily, reducing its resource. Sleep mode is sufficient for normal use.

Mac laptops go to sleep by themselves if you close them or shut them down.

Adjust the power

You can adjust the flow using the power setting. To do this, go to Control Panel Hardware and Sound Power Options. You can choose balanced or high performance mode. There are also settings inside that you can control to reduce energy consumption.

Reduce screen brightness and sound

A significant part of the energy is consumed by the screen. The higher the brightness, the more power consumption and harm to the eyes. Reduce the brightness to a comfortable level and, if possible, turn off the key backlighting, make the sound of speakers or headphones quieter.

Prevent your laptop from overheating

Lithium-ion batteries do not tolerate heat well. The optimum operating temperature for laptops is 10–35 degrees, and they can be stored at temperatures ranging from –20 to 45 degrees. Ensure that the ventilation holes are open during operation. Sometimes they can become clogged with dust. You can clean them with compressed air sold in cylinders. For Apple devices, cleaning the cooling system is possible only in services.

Reconfigure your graphics card

Your laptop can be equipped with an AMD or NVIDIA graphics chip. A powerful graphics card is needed for some programs or video games. If you do not use them, then switch in the settings to a simplified version of the work, which consumes less energy.

Do not completely discharge the battery

The battery is not a consumable item, but it has a limited number of charge cycles depending on the model. The less often you charge the battery, the longer the battery life.

Discard the screensaver

If you are not using a computer, then it is better to turn off the screensaver or put the laptop into hibernation mode.

Disconnecting unnecessary equipment

Aside from power-hungry apps, if you’re trying to squeeze as much battery life out of your battery as possible while traveling, it’s best to turn off any unnecessary equipment or features. Now is the time to turn off Wi-Fi if you don’t need it, or Bluetooth.

Don’t go crazy disabling every little hardware feature you need to just buy a little more time, but if you don’t need some of these power-hungry features right now, be sure to disable them.

Use hibernation whenever possible

You may be tempted to simply close your laptop screen every time you are not using it to save as much battery life as possible, which is a good idea. But if possible, use hibernation instead. The difference is simple. in this mode, your laptop does not consume any energy at all. and during “sleep” it is still consumed, although much less.

On macOS, there is no difference between these two modes; for Windows 8 and 10, thanks to modern power management, this may be slightly less important. The difference in these two modes won’t matter if you close it for a short period of time, but if you disable it between work sessions, using hibernation mode will help save a little power even on Windows tablets.

10 Ways to Extend Your Laptop Battery Life

There is nothing good when the laptop turns off unexpectedly in the midst of work, and there is no outlet nearby in order to recharge the battery. For those who often have to work on the go, there are some simple tips on how to extend the battery life of your laptop, both as a last resort and before leaving home.

Configuring Built-in Power Saving Options

It’s actually easy to do: check out your laptop’s power management features. In Windows, this is Power Options, which you can invoke by clicking Start. On macOS, this is in System Preferences under Energy Saving. Keep this in mind and don’t assume that the default settings are for power saving. If you know you won’t be home soon with your laptop, set it up to use as little power as possible before you leave.

What’s more, you can easily toggle these functions using hotkeys (in Windows at least) and configure your laptop to warn you about battery status, preventing you from being caught off guard.

Try not to completely drain the battery

There are different opinions about whether it is good or bad for a battery to completely discharge it. However, one thing is certain: most batteries have a finite number of charge cycles, after which their efficiency drops significantly.

In addition, the very problem of completely discharging the battery and then having to recharge it to the point where your device can work again is troublesome. If your battery is nearly depleted, stop using and close the laptop. Do not let the battery drain completely.

Adjusting the brightness of the monitor

If you realize that a laptop shutdown is just around the corner, and you don’t have access to an outlet yet, the first thing you can do is minimize the power to your PC’s biggest power drawer: the screen. Obviously, when your laptop is not in use, it will sleep, but when it is in use, you can save a little power by keeping the screen brightness as low as possible for use.

That being said, keep in mind that a dark screen will give you a few more minutes of battery life, but you won’t get the extra hour you need to get back to the office or home. Consider this an emergency measure.

Disable power-hungry apps and processes

Along with minimizing the brightness of your laptop’s display, doing one more step will help conserve energy. Before it shuts down completely, while the battery is low, turn off any power-hungry apps or tools that are running in the background while you work. This is another old tip, it goes back to the days when you could have tons of background processes consuming energy, there were actually more of them once than today. But in any case, it is worth keeping an eye on them.

This rule is even more important for mobile devices such as smartphones and tablets than it is for Windows and macOS, but the last thing you really want when you only have 45 minutes of battery life is to find out that you have all that time. a torrent application was running in the background and filled up or Photoshop continued to run because you didn’t close the program after you finished working with it.

Use battery service tools from your laptop manufacturer

Some of them offer their own battery maintenance tools. They provide the user with information on the condition of the battery as well as recommendations for extending its maximum battery life. For example, Sony and Lenovo have battery service panels or their own utilities, depending on the version of Windows you are using.

They also contain information on important topics such as battery calibration and how often you should fully discharge the battery (or vice versa, how often you should fully charge it).

Tips to Extend Your Laptop Battery Life

Adjusting power settings
We’ll have to switch to energy saving mode. It determines the time when the screen turns off when the user is not active. The shorter this period, the more battery charge can be saved.

Dimming the brightness
The backlighting of a laptop like the 2F3G0EA or any other consumes a lot of energy. Use F1 and F2 keys to decrease / increase brightness.

Turn off for the night
Just slamming the laptop lid down isn’t enough. It is advisable to spend a couple of seconds pressing the off button and the system will pay back by clearing the cache and a well “rested” device for the night.

Hibernation, not sleep
When a laptop like 81YH00NSRA is in sleep mode, it continues to use memory and battery power. Going into hibernation, the device remembers the current state and completely turns off the power supply.

Getting rid of garbage
Superfluous slows down the system, makes it spend more time and energy for processing and executing user commands. Therefore, we do not regret the cache and unnecessary files. Delete without hesitation.

Disable unused devices
For example, USB, external hard drive, webcam. All these gadgets, even when not in use, draw valuable energy from the laptop.

Cutting down Wi-Fi and Bluetooth
They are constantly looking for an opportunity to connect to other gadgets, which takes a lot of energy. If you don’t need a wireless connection right now, deactivate both functions.

We organize comfortable conditions
How do I take care of my laptop battery so it doesn’t get damaged? We protect the device from direct sunlight, do not install it in damp rooms, near heat sources (heater, battery). Notebook works best at moderate temperatures. Heat or extreme cold forces the battery to actively use energy, require recharging faster.

In addition, the unit needs a constant supply of fresh air through the ventilation openings. Therefore, we remove the laptop from our knees, bed and other surfaces, which impedes the access of the air flow.

You can and should use specials. coasters. They provide heat removal and air flow to the laptop, eliminating overheating. Models can be equipped with backlighting and additional USB ports, such as 21962_TRUST or “Riser” stand, have other chips.

How not to kill your laptop battery and extend its life: 8 valuable tips

The laptop battery can withstand ≈ 500-1000 charge / discharge cycles. This is several years of trouble-free battery life without constantly looking for a power outlet or buying a new battery. But its lifespan can be significantly reduced if you do not adhere to the elementary rules of operating the device itself and its battery. How not to kill your laptop battery.

Do I need to discharge the battery

It is not recommended to discharge the battery to zero. It is better to connect the laptop to the network with a charge of at least 10-20% to avoid unnecessary load on the battery.

When using a laptop, the battery goes through recharge cycles. 1 cycle not always = 1 charge. Only when the battery is powered from 0 to 100%.

After reaching a certain number of cycles, the battery life of the laptop decreases. What’s the best way to use your laptop battery? Keep charge between 50 and 80%.

Many manufacturers have provided the ability to automatically monitor battery charging. This is done using proprietary prog. For example, ASUS notebooks have a preinstalled Battery Health Charging utility, which allows users to choose one of three operating modes of the battery: full power (100%), balanced (80%), maximum service life (60%).

We will talk about other programs for power management of a laptop akka below.

Battery software

Utilities such as:

Will tell the general information about the battery: capacity, current charge, discharge cycles, wear, last calibration date, CPU and HDD temperature, etc. You can select a power plan, set the time to turn off the display.

It will provide data on the charging and operating time of the battery, its capacity, voltage, the number of recharge cycles, etc. The utility will inform you when the battery charge has dropped below the specified value. Mini-program allows you to build a graph and analyze battery performance.

It will inform you about the full and current capacity of the battery, the approximate operating time at this rate, the degree of wear of the battery, etc. Keeps a log of battery use, updated automatically.

There are other similar programs freely available on the internet. To install, just download the utility. The installation process is elementary: click on the downloaded file, accept the user agreement and press “next”. Wait until the end of the process. The utilities have a simple, intuitive interface (even non-Russianized options).

Apple Mac owners can also monitor battery aging using programs such as coconutBattery or the MONIT widget. Allows you to track the age and condition of the battery, notify when it is time to charge it.

The main information about the programs for the battery of a portable device:

Proper use of a laptop battery is the key to its longevity. Not worth it:

  • drop the device;
  • overload;
  • keep constantly connected to the network;
  • make it work above / below the recommended temperature threshold.

Use special programs to keep an eye on the state of the battery, and follow the simple rules described above. This will allow the laptop battery to last a long time.

How to Extend Laptop Battery Life and Battery Level: Tips

This article contains essential points on how to maintain laptop battery levels for users of all levels. What happens if you recharge your laptop battery? The answer is as short as possible: nothing. If you leave your laptop on charge after a full charge, nothing will happen to it.

Lithium-ion batteries

Most modern computers run on lithium-ion batteries. They can be recharged hundreds of times without affecting the longevity of the battery. There is a cycle inside that stops the charging process when the battery is fully charged. Without this cycle, it would heat up during charging and could easily burn out. Such batteries should not heat up, if this happened, then you have a defective product in front of you.

Conserving energy in “Windows 10

In “Windows 10”, Power Save Mode is automatically enabled when the laptop battery reaches 20%. Depending on the settings, the screen brightness is dimmed to conserve battery power longer. To check this, go to “System and Security” in the control panel, then to the power settings. All changes can be made manually. To conserve the battery, it is advised to keep Bluetooth off at all times. If you do not use the Internet, you can temporarily put your laptop in the “Airplane mode” state, which will significantly save the device’s battery level.

Extending battery life

To extend the battery life, after purchase, leave the laptop on charge for 12 hours before use. Li-ion batteries can last longer if the battery level is kept between 20-80% at all times. Although constant charging does not greatly affect lithium-ion batteries, it is still advisable to remove it if the laptop is constantly connected to the mains.

If you are not going to use the laptop for a month or longer, then remove the battery. If it is not removable, then the battery level should be left less than 50% before closing. If left uncharged for a long time, the battery may be damaged. High temperature fluctuations should also be avoided. Do not leave the computer in a closed car in hot summer under the sun or too frosty in winter.

Batteries on MacBooks

Apple manufactures devices with built-in lithium-ion polymer batteries to save space and compactness. To check the battery status, you need to click on the Option button and click on the battery level indicator in the quick access panel. After that, several messages may appear:

  • Replace soon. the battery functions normally, but holds less charge than when it was new.
  • “Replace urgently”. the part functions normally, but holds significantly less charge than when it was new. The computer will work, but the condition of the battery may negatively affect its performance, so you need to take the computer to an authorized Apple service to have it replaced.
  • Show service. the battery is functioning properly. MacBook can be used when it is connected to the mains.


The older generation of laptops runs on nickel-cadmium batteries. They require more frequent repair and replacement than lithium-ion ones. Once a month, the battery must be fully charged and discharged, this helps to prolong its life. As with lithium-ion batteries, leaving them on charge after a full charge will not affect their lifespan in any way.

Extending battery life

To extend battery life between recharges, you can:

  • decrease screen brightness;
  • set a time for sleep mode and a timer to turn off the screen for a short period;
  • turn off Wi-Fi and Bluetooth;
  • close unnecessary tasks in the “Manager”;
  • close unnecessary browser tabs;
  • do not block the access of air to the cooler (the battery quickly sits down when heated);
  • remove unused USB cables and disks;

No battery is guaranteed for a lifetime, so from time to time, old batteries should be replaced with new ones. If the old one is still capable of holding 15-20 minutes of charging, you can take it with you on long-term trips to replace it with another in case of emergency.

Follow these tips to save battery life, avoid using a laptop connected to the mains all the time, then you will notice how surprisingly long the battery will last.

How to Extend Laptop Battery Life

To keep your portable buddy portable in the future, take on four practical tips.

Keep track of the temperature

Battery life is critically affected by temperature. It does not matter in which direction the thermometer creeps, both low and high temperatures adversely affect the battery. So that it does not overheat and not hypothermia:

  • Work behind your laptop on flat, hard surfaces (desk, desk, wide windowsill). Many (especially girls) are accustomed to keeping a switched on laptop on the couch, carpet, etc. Why is that bad? Such surfaces cover special ventilation gaps, which are provided for heat dissipation. In some cases, the laptop can heat up to 50 ° C.
  • Do not expose the laptop to direct sunlight, which can significantly shorten battery life.
  • Do not take or use your laptop in freezing temperatures. Even if you carry your laptop in a special bag, make sure to get into a warm room within 15 minutes. This is how long it takes for the batteries to cool down to air temperature. Keep in mind that cold is destructive for a battery. it loses capacity very quickly.

Do not use Stand By mode for other purposes

Many users prefer to use standby as an alternative to shutdown, forgetting that it is designed to reduce device power consumption when idle.

You can close the laptop lid without first turning it off only when you plan to return to the device in the next 2-3 hours.

The specificity of the standby mode is that it puts the computer into a low power consumption mode, which allows you to quickly resume a Windows session.

When activated, the screen, hard drive and adapters are turned off, but the RAM and CPU, keyboard and touchpad are still working. It turns out that individual components continue to work, absorb energy and the battery, including.

How to Extend Laptop Battery Life

Laptop battery life is an important characteristic that is fundamental to many consumers. Unfortunately, over time, batteries wear out and lose capacity. This is especially true in relation to production devices, the processor of which is deliberately overclocked to increase their performance.

To extend the battery life for your laptop and to keep it from shutting down at the most inopportune moment after years of use, follow our recommendations.

A Few Cognitive Facts About Laptop Batteries

The laptop battery is a consumable item. It cannot be repaired. Out of order. dispose of it in accordance with established standards and replace with a new one.

Most modern laptop batteries are lithium-ion (Li-Ion). Their lifespan is directly related to charge / discharge cycles. Li-ion battery before laptop is rated for approximately 300-400 charge / discharge cycles, equivalent to 2-3 years.

It should be noted that the charging cycle means a set of processes associated with filling the battery with energy and completely discharging it.

Less popular lithium polymer (Li-pol) batteries, which are used in Apple mobile gadgets and portable devices. On average, such batteries can withstand about 800-900 charging cycles and can work for about 5-6 years.

often than not, batteries become unusable due to improper use. How to extend battery life will be discussed in the next section of the article.

Strictly follow the charging / discharging rules

The first and foremost thing to know is that the battery must run periodically. Otherwise, it will simply grow old and become unusable.

If you are using AC power, be sure to remove the battery. In this case, it is important to observe a certain percentage of the charge. If you are away for a long time (more than a month) charge the battery by 50%. In the case when, for example, you plan to visit relatives, and the laptop will simply gather dust for several days, remove the battery at 10% charge.

When removing the battery from the laptop, and working from the mains, it is highly advisable to connect a UPS (uninterruptible power supply). Otherwise, in the event of an emergency power outage, the device may fail, and you will have to spend serious money to restore it.

Even if a laptop replaces your desktop computer, make it a rule to switch to battery operation every 4-5 days and at the same time fully charge and discharge it, that is, perform one cycle.

It is recommended that you completely drain the battery once every two months and then charge it to 100%. This is done in order to calibrate the flow meter. If you ignore this, the flow meter will lose accuracy and the laptop will shutdown even when the indicator shows that there is a charge.

Be sure to turn off the device before removing or inserting the battery.

If you systematically work on your laptop in offline mode, make sure that the charge indicator does not drop below 20%. When the charge drops to the indicated figure, turn off the device.

If we talk about the upper limit. do not charge the laptop more than 80%.

The optimum temperature for storing the battery is 20-25 ° C.

Configure the system correctly

To extend battery life and laptop battery life, properly configure Windows.

  • Turn off the keyboard backlight. To do this, use the hotkey combination Fn and, depending on the keyboard layout, F1-F12. To make it clearer, we attach a screen.
  • Decrease the brightness of the screen. Go to the start menu. Select the Settings tab → System.

To decrease the brightness, move the slider to the left.

  • Turn on battery saver. In the same parameter settings, go to the “Battery” tab and mark the checkboxes as in the picture.
  • Edit the Power & Sleep settings for you.

As you can see, the battery life of a laptop directly depends on a few simple rules and settings that even a novice user can handle.

I would like to believe that this small manual will save the lives of many batteries. You may have your own methods of extending the battery life. If so, share them in the comments.

How to Extend Laptop Battery Life: Practical Tips

The laptop battery is equated by manufacturers to consumables, and their average service life is 2 years (from 300 to 800 charge / discharge cycles), which is much less than the service life of the laptop itself. What can affect the performance of the battery and how you can extend its service life, we will tell you below.

How to make your laptop battery last longer

All modern laptops use two main types of batteries:

  • Li-Ion (lithium-ion);
  • Li-Pol (lithium polymer).

Modern laptops use lithium-ion or lithium-polymer batteries

Both types of batteries have the same principle of accumulating an electric charge. there is a cathode on an aluminum substrate, an anode on a copper one, and between them there is a porous separator impregnated with electrolyte. Lithium-polymer batteries use a gel-like electrolyte, which slows down the lithium decay process, which increases their average working life.

The main disadvantage of such batteries is that they are subject to “aging” and gradually lose their capacity reserve. This process is accelerated by:

  • overheating of the battery (temperature over 60 ºC is critical);
  • deep discharge (in batteries consisting of a bundle of 18650 cells, the critically low voltage is 2.5 V and below);
  • overcharge;
  • freezing of the electrolyte (when its temperature drops below the minus mark).

As for the charge / discharge cycles, experts recommend not to allow the battery to be completely discharged, that is, to recharge the laptop when the battery charge indicator shows a mark of 20-30%. This will increase the number of charge / discharge cycles by approximately 1.5 times, after which the battery will begin to lose its capacity.

It is not recommended to completely discharge the battery

Also, to increase the resource, you should adhere to the following recommendations:

  • If the laptop is used primarily in stationary mode, then the battery should be charged to 75-80%, disconnected and stored separately at room temperature (10-20 ºC is ideal).
  • When the battery is completely discharged, charge it as soon as possible. Long-term storage of a discharged battery significantly reduces its capacity, and in some cases even leads to blocking of the controller. in this case, the battery will completely fail.
  • At least once every 3-5 months, you should completely discharge the battery and immediately charge it to 100%. this is necessary to calibrate the controller board.
  • When charging the battery, do not run resource-intensive applications so as not to expose the battery to overheating.
  • Do not charge the battery at low ambient temperatures. when moving to a warm room, the voltage on a fully charged battery will increase by about 5–20%, which is an overcharge.

But with all this, each battery has a built-in controller. Its task is to prevent a decrease or increase in voltage to critical levels, to adjust the charge current (to prevent overheating), to calibrate the “cans”. So you shouldn’t bother too much about the above rules. many of the nuances have already been provided for by the laptop manufacturers themselves, so that the use of such technology is as simple as possible for the consumer.

When a laptop battery gets too hot, electrochemical reactions are accelerated inside the laptop, but this does not mean that the battery is performing more efficiently. A rise in temperature indicates that the battery is producing too much energy that it cannot use and cannot safely channel onto any equipment, which creates even more heat, thereby exacerbating the problem. Not only can this ultimately harm the component, but it also wears it out due to a variety of chemical reactions.

Modern lithium-ion batteries are durable, but they cannot withstand enormous amounts of heat. For example, if you are charging the battery and it starts to heat up excessively, perhaps because the CPU or video card is running at full capacity, or the user’s area is too hot, you should turn off the device and remove the battery if possible. Give it a “rest” to cool it down, or move to a place with a lower air temperature. However, given that many modern laptops are equipped with non-removable batteries, it is highly recommended that you turn off the device and let it cool down if you care about your battery as much as possible.

Also, avoid using the laptop on your lap or bed, as this will affect the cooling of the device.

Battery reporting software

Yes, understanding how a battery actually works is quite difficult. For example, devices such as iPhones have built-in battery maintenance settings and alerts that provide at least some information, but this type of diagnostic data is more difficult to find on laptops. Therefore, we decided to put together a few battery monitoring apps that are worth paying attention to.

Unnecessary recommendations and advice

Old-timers will probably remember the effect called “battery memory”. It was because of him that nickel-metal hydride (NiMH) batteries lost their full capacity over time, and could only be charged to a certain percentage (but not full). The battery seemed to “remember” that its capacity had not been fully used in previous cycles.

Fortunately, this problem no longer exists thanks to modern lithium-ion batteries, but the effect has led to a lot of silly battery care advice and arguments based on outdated information. But it’s time to put all these rumors to nothing.

Contrary to some guidelines, you do not need to regularly fully discharge a lithium-ion battery and then fully charge it to perform a “calibration”. this is actually a destructive practice that has a detrimental effect on the battery.!

However, the answer to the question of whether it is worth doing a full discharge a couple of times a year remains open. In general, there is general consensus that it is best to discharge the battery to about 20% and then fully charge (if possible).

Then many said that you should not leave your devices connected to the network, since when the battery reaches 100% charge, the battery wears out faster. However, the fact is that modern devices stop charging when they reach 100%. Therefore, according to some experts, network connection does not affect battery life in any way.

This also applies to laptops, since there is a lot of discussion about whether or not to leave a laptop connected to the network if it is already charged to 100%. However, there is nothing wrong with shutting down your computer and unplugging it from the charger, if that’s more convenient for you.

But generally speaking, the best thing you can do to keep your lithium-ion battery in good condition is not to discharge it below 20%. Plug in and charge your device whenever you can. The good news is that today’s batteries and systems are really smart and you don’t really need to do anything. But you still need to wait for the battery to eventually begin to lose capacity (it’s important to remember that this is, after all, a consumable).

Finally, if you are not going to use your laptop for a long time, then you need to discharge or charge it to 50%. This applies not only to computers, but also to any other modern device.

Leave your laptop connected to the network (but not always)

Most modern laptops can be left plugged in without any problems. In addition, all powerful gaming devices work best with a charger. The most important aspect of a battery’s health is its discharge cycle. No matter how careful you are, the battery degrades anyway as it charges and discharges. When running an intensive application such as a video game, it is worth connecting the laptop to a charger to reduce the same number of discharge cycles.

However, don’t leave your laptop like this all the time. Only do this when you are running heavy applications. As mentioned, it’s better to keep your battery 40%.50% charged than 100% charged if you don’t plan on using the device for a while. Fully charged batteries that are left unattended decompose faster, especially at high temperatures.

So, if you are not on the road or using an intensive application, it is recommended that you leave your laptop connected to the network. If you are doing everyday tasks that use less energy, such as browsing the web, then the laptop will cope without any problems, running only on battery power.

How to extend laptop battery life

A few years ago, replaceable batteries were common, but nowadays laptop manufacturers are increasingly equipping their devices with non-removable batteries, making proper care of this component more important than ever. In our guide, we have collected some tips, tricks and best practices to help you extend your laptop battery life.

Before we start, it’s important to note that every laptop is completely different. However, our advice applies to most modern devices from major manufacturers. If you have an older laptop. say five years or older. you can still use our guidelines to get the most out of your battery. However, it is still recommended that you familiarize yourself with the information about the specific laptop model.

Save cycles and battery power

All laptop batteries are designed for a specified number of charge cycles. Usually the figure is about 500 full cycles, and sometimes more. Many do not fully understand the meaning of this term, since a charge cycle is equal to one full discharge to 0%, and then recharging to 100%. So, for example, discharging to 50% and then charging to 100% is equal to half a cycle. Each cycle will reduce the capacity of the battery over time from its original specification. This means the less often you discharge your battery, the longer it will last, all other things being equal.

So where do you start? Well, it’s worth heading to your laptop’s power settings menu and finding out how the battery works and what options you need to enable. Also pay attention to the hibernation modes. Ideally, the laptop should go to sleep before the battery is completely discharged, and also during idle times when the laptop has not been used for some time.

To save even more battery, check the list of enabled apps and close those running in the background and consuming battery power. For example, Windows 10 offers a battery saver feature. The mode automatically turns on when the device reaches about 20% of the charge (we will explain why this is especially important below). The feature automatically locks background apps and prevents syncing in some apps such as Calendar, disables sending notifications, dims the screen, and makes other changes that will ultimately save battery power and extend battery life.

For MacBooks, try enabling Power Nap to put your computer to sleep. It will also extend battery life. Enabling automatic graphics switching can also help reduce power consumption. the function is to switch to low graphics mode when performing simple tasks (such as working with text).

Plus, you can make a lot of manual changes. Cloud storage services or video players that you don’t use can also be safely turned off. It is possible to manually reduce the amount of energy consumed by turning off Wi-Fi and Bluetooth when not in use, as well as the keyboard backlight. Note that both Microsoft and Apple have guides for saving battery power.


A small application developed for Windows computers. The tool provides notifications, CPU temperature readings, discharge cycle monitoring, capacity and many other useful information.

How to extend laptop battery life?

In this article, you can read how many tips, following which, you can increase the battery life of your laptop.

Due to the technical features of laptop batteries, manufacturers do not provide for the possibility of repairing them by the users themselves. Actually, that’s why they are sold in non-separable cases.

However, now there are many workshops specializing in the repair and restoration of batteries.

There are times when a lithium-ion battery simply loses its previous performance or stops working altogether for some reason. One way or another, one day the time comes when the user realizes that it is time to contact the service center or replace the battery with a new one.

Laptop battery

Let’s see what you can do to postpone this sad moment or what to do if it has already come.

On average, a typical laptop battery is rated for about 150-200 full cycles (i.e. a full cycle is one charge-discharge of the battery). With fairly frequent use, if, for example, one or two cycles occur a day, the battery can last for six months.

However, users often alternate between battery operation and mains operation. this approach can be considered normal. However, the masters advise keeping the laptop on charge in general continuously.

At the same time, you should not try to charge the battery yourself if it has completely “sat down”, because improper charging can adversely affect the performance of this battery. Another disadvantage of Chinese batteries is that outdated, cheap, and in some cases even used cells with modern electronics and a native controller are used for their production.

So let’s imagine that in the end, your laptop battery is completely out of order. In this case, the repairmen in the repair service will be able to fix the problem literally within a day, or simply replace the battery cells in just two to three hours. However, there are times when the battery can no longer be saved, then in the same service they will pick up a similar one for you. After repairs, you must definitely give a warranty on the battery, at least for a short period. However, then the battery capacity often decreases by about 10-15% after only 1-2 months of active use.

In order for the battery to last as long as possible, you should adhere to the following tips:

  • Do not allow the battery to be completely discharged, and if this happens, do not leave it in this state for a long time, because in an “empty” battery, the controller may stop functioning, which will entail a problem with the laptop recognizing the battery. over, not only the controller can suffer, but also some other elements inside the battery. Therefore, if you are not going to use your laptop for a long enough period, then before that you definitely need to charge the battery as much as possible.
  • Some experts advise, if possible, not to disconnect the laptop from the network at all.
  • Never turn on your laptop indoors or outdoors, where the air temperature is below zero. It is possible to transport the laptop in the off state in such conditions. But if you want your battery to last as long as possible, never turn it on in low temperatures.
  • It is also impossible to heat the battery, because nothing good will come of it. The fact is that low or high temperatures directly affect the chemical process inside the battery, especially if energy is released to power the laptop. Therefore, with strong drops and it is not recommended to turn it on.
  • If you are a jack of all trades or just like to see what this or that element of the computer is made of, then we do not recommend that you try to “reanimate” a dead battery on your own. It would still be better to contact the service, where experienced professionals, using the appropriate equipment, will diagnose your battery and fix the problem.

How to extend laptop battery life?

Laptops and netbooks are gaining in popularity every day, despite somewhat higher compared to their stationary brothers. This is due to the fact that the main stake in the modern world is on mobility and autonomy.

I bought a laptop myself two years ago. At first, he worked all the time from the network, but then there was a need for autonomous work. And then the question arose before me about the battery life and the extension of the operating time from a single charge. Naturally, I started looking for information on the net. Break many sites and forums, I found a lot of interesting and unexpected things for myself, than now I want to share with you.

Advice 1. The battery charge is used by absolutely all enabled devices on the laptop, therefore, when operating on battery power, you should disconnect unused equipment in the device manager (the main consumers that can be turned off: wi-fi adapters, bluetooth and infrared port, all modules for connecting additional monitors, you can also temporarily disable all USB controllers, then network cards and built-in modems, etc.)

If you have not figured out what can be turned off and what not, then a small Battery Double program will help you, which automatically turns off unused hardware and can put the processor and hard drive into economical modes.

Tip 2. Set the screen backlight to the lowest brightness (on some operating systems this is done automatically).

Tip 3: Avoid using a DVD or CD drive if possible. its motor consumes a lot of energy (if there is an urgent need to use a DVD drive, then transfer the necessary files directly to the hard disk, and then remove the CD or DVD and work with these files from the hard disk). Battery Double automatically shuts down unused hardware

Tip 4. If you are going to interrupt work for at least half an hour, then do not leave the laptop turned on, but send it to sleep or hibernation. Do not send to standby mode, because the processor, RAM and keyboard still work.

By following these tips, you can extend your battery life on a single charge. The following tips will help you maintain the performance and capacity of your laptop battery for years to come.

Tip 5. If you intend to work on a laptop from the network (a month or more) for a long time, then it would be better to charge the battery to 50% and put it in a cool place of 10-15 degrees. In this mode, the battery loses only 2% of its capacity per year.

Tip 6. Battery life is measured by the number of complete charge-discharge cycles, so charging to 100%, then discharging to 50% and then charging to 100% again will be considered half a cycle. But according to the manufacturers, a full 100%.0%.100% cycle should be performed at least once every two months for better safety and stability of the battery. Let the battery discharge periodically

Tip 7. Do not be lazy to read the user manual for your mobile device. it happens that useful information is written there.

If you follow all these tips, the battery will actually last longer, and therefore you do not have to often (every 1-2 years) change it to a new one, because it is not so cheap. from 80

Some information about laptop battery design

So. laptop battery.

Location of laptop battery

The device of a laptop battery is such that inside it, plates of special metals immersed in a special solution (usually acid or alkali), give part of their substance into the solution or take this substance back from the solution under the action of an electric current.

A so-called reversible chemical reaction takes place inside the battery. When it flows in the “forward” direction (battery discharge), the battery gives up electrical energy to consumers, and when it flows in the “reverse” direction (charging the laptop battery), the battery again accumulates this electrical energy. Therefore, its name contains the word “battery”, i.e. capable of storing, storing electrical energy.

Why “battery”? Because, as a rule, one battery is not enough to provide the power required to power the laptop. Therefore, the batteries are connected to each other in a so-called “battery”. Hence the name “rechargeable battery”.

This reversible chemical reaction cannot go on forever. After a certain number of charge-discharge cycles, the chemical reaction first weakens, and then stops altogether. And, accordingly, the battery “orders to live long”.

How to properly use your laptop battery

Electricity. People have long been accustomed to this. Now it’s hard to imagine life without the usual 220V AC outlets.

However, there are places where it is not possible to connect to household AC power. For example, in transport, outside the home, on the street, in nature.

The cars have power supply, but this is not 220V, there are completely different standards. In public places (train stations, libraries, theaters, lecture halls in educational institutions, etc.) it is also not easy to find a connection point to 220V.

But what if you need a laptop power supply? After all, laptops (as well as netbooks, tablets and other mobile devices) are designed not only to work in a home or office, but also in so-called mobile conditions, when there are no usual “wired” communications: 220V, wired Internet, etc.

In this case, their developers, for example, provide various options for connecting to the wireless Internet. What about wireless power?

As for the electric power supply, then mankind has not yet come up with anything new, except for rechargeable batteries. There are, of course, laboratory developments on wireless power transmission. But while all this is cumbersome, expensive, unsafe.

What will shorten laptop battery life?

With the CORRECT use of the battery, it is impossible to extend the life of the battery, which is calculated in terms of the average values ​​of the discharge-charge cycles. How many times it should be discharged and recharged, this will be the battery life of the laptop. However, if the battery is used INCORRECTLY, the battery life of the laptop can be drastically reduced.

For example, if the battery is stored for a long time in a completely discharged state (when the laptop battery indicator shows 0% or close to zero), damage to the battery plates (which, as we already remember, are in a very “unpleasant” acid or alkali solution) is possible, and then the battery completely fails.

Or, for example, in case of intense shaking or shock in the laptop battery, the plates may short circuit, which will lead to the discharge of the battery “from the inside” and the impossibility of subsequent charging, i.e. to spoil.

Laptop batteries don’t like frost. No, the solution of acid or alkali in them does not freeze even in the most severe frosts. But the lower the ambient temperature, the lower the battery capacity becomes, i.e. its ability to deliver accumulated electricity for a long time decreases.

Laptop batteries don’t like overheating either. Since they themselves heat up during discharge and during charging too. Additional heating is not necessary for laptop batteries at all, whether it be direct sunlight or a heated surface on which the laptop is installed.

The difference between a laptop and a stationary computer

Laptops and desktop PCs are, of course, different from each other. Laptops are portable, for work even in the “field” conditions, where there is no possibility of connecting to the usual power sources and to the wired Internet. Stationary PCs work in a home or office, they are powered from 220V, and, as a rule, have a wired connection to the Internet or office (home) Wi-Fi.

We are not considering the Internet now, but we are looking at the differences in connection to the power supply. So, if a laptop is used in an office or at home, then there is a temptation to connect it to a regular 220V outlet via a charger and work on it like on a stationary PC. And such a desire is correct.

However, we must not forget about an important difference in the power supply systems of a laptop and a stationary PC, and this will extend the battery life of the laptop.

The laptop battery does not like it very much when the laptop is turned off, but at the same time it remains connected through the charger to the 220V electrical network.

The fundamental difference between a laptop and a stationary computer is that a laptop (more precisely, its charger) must ALWAYS be disconnected from the 220V outlet after turning off, and a stationary computer is not necessary.

It is important to remember this, and always observe this simple rule: turn off the laptop. disconnect its charger from 220V.

As a teenager, my daughter was never taught to unplug the laptop after turning off the PC. The result. a little over a year later, the battery “ordered to live a long time.” I had to remove the battery from the laptop altogether, since it deteriorated so much that the laptop did not turn on at all even with the charger turned on. And since then the laptop worked without a battery, only from a 220V network, like a stationary PC.

Usually, replacing a laptop battery is very expensive, and can cost up to half the cost of a laptop. Therefore, the laptop battery must be protected! At least for economic reasons.

However, in more detail the question of in what cases the laptop can be turned off and at the same time left connected to the 220V electrical network, we will consider in another article. This also happens, although more often, as an exception to the above rule. And exceptions, as you know, only confirm the rules.!

In general, the laptop battery needs to be used CORRECTLY so that it lasts as long as it has a discharge-charge cycle.

Laptop battery life

Laptop battery life on average ranges from 500 to 1000 full charge and discharge cycles, depending on the manufacturer. Almost always, original rechargeable batteries last longer than copies and compatible counterparts, however, their price is higher. The battery life is significantly reduced by improper operation: the process of a reversible chemical reaction is disrupted, and the battery eventually ceases to hold a charge, after which it has to be replaced.

Why does the battery fail??

Any battery in a laptop battery consists of a metal plate placed in an acid or alkali solution. Under the influence of electromechanical processes, they give up part of their substance, and then take it back. Over time, the intensity of the chemical reaction weakens, after which it completely stops. Battery life with proper use is 3-5 years, however, it can be significantly reduced under the influence of the following factors:

  • Long-term storage in a discharged state is fatal to the battery. In this case, the plates of the batteries deteriorate, after which recharging is impossible.
  • Intense shaking, shocks and other mechanical damage lead to the closure of the plates, as a result of which the normal charging process is disrupted.
  • Lithium-ion batteries, which are the most common today, do not like working in subzero temperatures. At the same time, the capacity decreases, that is, the battery begins to lose the ability to give up the accumulated energy.
  • The service life is also reduced due to overheating. Direct sunlight and location near heaters have a negative impact.

How to extend battery life?

Extending the battery life of a laptop requires adherence to the charge mode. The optimal level is 50-70%, therefore it is not recommended to keep the device permanently connected to the mains. If the laptop is used at home as a stationary computer, it is recommended to separate the battery during operation and then reconnect it. over, it should not lie discharged for a long time. At least twice a month, it must be fully charged and discharged so that the capacity does not decrease.

How to extend laptop battery life and increase battery life? You need to follow a few simple rules:

  • The laptop must be placed on a solid surface and the cooling holes must not be blocked. Special stands with a built-in cooler will help to avoid overheating of the battery.
  • It is undesirable to allow a complete discharge of the battery. If the charge level is close to 10-20%, stop working and look for an opportunity to recharge from the mains.
  • To increase the duration of battery life, it is necessary to disable all extraneous and additional functions. It is worth reducing the number of startup programs, turning off the Wi-Fi and Bluetooth module if they are not needed right now. If work needs to be interrupted, the device must be put into sleep mode to save battery power.

A dedicated laptop battery life extension software such as Battery Optimizer will show you which functions can be temporarily disabled to save money, and it will also show you how much the battery is worn out.
