Computer literacy with Hope. Filling in the Gaps. Expanding the Horizons! 7 rules for using laptop batteries
The block cannot last forever,
but you can extend the period of its flawless work.
The block is not forever. Eternal laptop batteries are NOT invented yet. But the battery life can be extended. How? Observing the following 7 rules for using the laptop battery.
Rule 1. When you turn on the laptop for the first time after buying it Wait until the unit is charged to 100%. DO NOT unplug your laptop and charger until this happens. Even if the laptop battery takes a long time to gain its charge.
At the same time, when you turn on the laptop for the first time after purchasing it, adjust the power settings to continue using the laptop battery. How to do it? In Windows 7: left-click on the battery icon located in the taskbar on the right side (more precisely, in the notification area), and select the “Advanced power options” option. You can also “get there” from the Control Panel “Start”. “Control Panel”. “Hardware and Sound”. “Power Supply”.
Recommended power settings have been listed in the “Automatically manage laptop power” article. However, these are only recommended parameters, since each user can and should adjust these parameters “for themselves” and for their laptop and for their own operating modes of the laptop battery.
Rule 2. When using the laptop for the first time (immediately after turning it on for the first time after purchase), it is recommended to fully discharge the battery three times and then immediately (without leaving the battery completely discharged for a long time!).
During a three-fold full discharge and battery charge, it is not recommended to load the laptop to the maximum (in terms of power consumption), for example, watching movies from DVD. Allow the battery to run at partial load for the first time. Thus, you will extend the battery life of your laptop in the future. It’s like driving a car, until you drive it in, you don’t need to drive at maximum speed.
Subsequently, repeat this cycle of full discharge and FULL charge of the battery three times approximately once a year. The phrase “FULL charge” means. up to 100%! Disable the maximum battery limit during this “workout”. see the following rule.
Rule 3: Limit the maximum battery level if the laptop management software allows you to adjust the maximum battery level. If there are such adjustments, they should be used immediately after completing a three-fold cycle of full battery discharge and subsequent full battery charge.
It is believed that limiting the maximum battery charge of a laptop to 80% or 50% will result in much longer battery life than if the maximum battery charge is at the usual 100%. At the same time, 80% should be installed by those laptop users who more often use a laptop from a battery outside the house and away from a 220V electrical network. And 50% should be installed by laptop users who use it mainly from a 220V network.
How to make these settings? Review your notebook documentation and if it contains recommendations for battery management, refer to them as soon as you complete the 3 discharge-to-charge cycle. When you set the maximum battery level to 80% or 50%, all subsequent rules are not overridden!
Rule 4. When using the laptop battery in the future, never leave the battery completely discharged for a long time. At the first opportunity, you need to immediately put it on charge if the battery is discharged to the minimum critical values (0%. 10%).
Rule 5. When using a laptop in the future, never leave the laptop turned off and at the same time connected to a charger, which in turn is connected to a 220V electrical network.
You can leave the laptop connected to the charger if at the time the laptop is turned off, its unit is not fully charged and needs to be charged to 100%. In this case, the laptop should remain connected to the charger only until the battery is fully charged. Then the laptop should be disconnected from the charger or the charger should be disconnected from the 220V network.
Rule 6. When using the laptop battery in the future, use the charger wherever there is access to a 220V network. This will reduce the number of discharge cycles. battery charges.
The duration of the correct operation of the laptop battery depends directly on the number of discharge cycles. charge, which this battery “lived”. The more THESE cycles are performed, the less the battery “lives”.
Rule 7. When using a laptop, exclude situations of uncontrolled discharge of the battery, up to a complete discharge.
What does this mean? For example, leaving a laptop indefinitely in the so-called standby mode (a mode when the laptop is turned off, but its state is recorded in the laptop‘s RAM for quick recovery when it is turned on again), the user risks forgetting about it for a long time. And the standby mode, albeit a little, but consumes electricity.
If you do not think about the laptop for a long time, then in standby mode you can completely discharge the battery. This means that it can fail with a high degree of probability.
You can also inadvertently forget for a long time about turning on and running on battery laptop. This will also cause a complete discharge of the battery, and rather quickly, in contrast to the economical standby mode, in a matter of hours.
For those who DO NOT rely on their memory, and who understands that they can forget about the included laptop for a long time, we can only advise you to set a high level of low battery power and almost complete battery discharge. For example, instead of the usual 10% and 5%, you can set 50% and 45%. Of course, this will halve the battery life of the laptop, but it will not completely drain the battery.
Summarizing all the rules for using a laptop battery, you can summarize how to extend battery life.
It is necessary to prevent a long stay of the laptop battery in a state of full (0%) or almost complete discharge (no more than 10%).
And SIMilarly, it is necessary to prevent a long stay of the battery in a state of full charge (100%) when the laptop is disconnected and at the same time when the laptop is connected to a 220-powered charger.
These are, in fact, all the rules for operating a laptop battery. They sound SIMple, it is not always possible to fulfill them, but you need to strive to fulfill them. And then the battery pack will not fail, and serve exactly as long as its developers and manufacturers have put in it. And they have already tried, and do not hesitate!
The cases described below are quite rare, but they did take place. Smartphones rarely catch fire, and they do it by themselves, without user intervention. Most often, such cases occur while charging the device, it is especially dangerous to charge them using fake chargers. This harms not only the battery, but can also destroy the smartphone user.
As for the mobile. The power controller will start to fail if the charger voltage differs from the “native” charger. Because of this, current can begin to flow to a fully charged battery, which at best will SIMply affect its service life. However, this may result in fire, explosion or melting of the battery inside the smartphone. The likelihood of such situations increases dramatically in the presence of an invisible factory defect in a mobile device. As a rule, manufacturers think over and insure against any cases, but it is impossible to pre-cook everything.
Can I use my phone while charging if it is fully functional? In any case, it is best to disconnect it from the charger at the time of use. As described above. Smartphones get warm while charging. The same thing happens during work. If the user is talking or worse. Plays, then heating occurs with even greater force. This destroys both the battery and increases the chance of an accident due to fire or explosion. In the consequences associated with this, you can guess for yourself.
Can I use my phone while charging
Modern devices are quite complex from a technical point of view. The increase in functionality causes additional energy consumption, which leads to an increase in battery capacity by phone manufacturers. At the same time, the devices themselves are getting smaller, the size of smartphone parts, various microcircuits, boards, processors and antennas.
However, the smaller size only increases the heat generation by mobile devices, and the batteries heat up. By the way, while charging, the battery heats up even without user intervention, even in standby mode. So, can you use your phone while charging? Obviously, at least this is NOT desirable.
Is it possible to use the phone while charging or not?
Can I use my mobile phone while charging? The question is quite relevant. Technology does not stand still, and our smartphones are becoming more and more functional. High-speed Internet, social networks, instant messengers and many other interesting and exciting things appear. It is difficult to tear yourself away from the phone screen, but sometimes you need to do this at least for your own safety and the safety of the device in working order.
Can I use my phone while charging? Comments, it is better not to do this. You should turn off your smartphone or unplug the power plug when using the phone. If you see that the battery or the case of the device is swollen, then it is better to disconnect it and contact the service center. Do NOT neglect this precaution: a faulty phone can at least stop working at the right time. You can also count on the replacement of the device if the warranty period has NOT expired yet, and the breakdowns are your fault.
What about power banks? Can I use my phone while charging with portable batteries? The situation is slightly different here. The voltage in portable batteries is slightly lower than that which is given to the phone battery from the mains. Based on this, the heating of the smartphone will be less. However, it is better not to play or use the smartphone for a long time while charging from portable batteries.
It is also better not to leave the phone unattended while charging, especially at night. Although the manufacturers have thought out everything, it is better not to risk it again. Power controller or battery defect may be invisible.
Now you know if you can use the phone while charging or not. DO NOT neglect these precautions: they can prolong the performance of your devices. By the way, SIMilar instructions are also applicable to tablets, in them the batteries are even more powerful, so NOT putting yourself in danger.
What are we testing on
As a test subject, we will use the Honor Play, a device designed for gamers. It, of course, is suitably equipped for this: The flagship Kirin 970 processor with the Mali-G72 MP12 graphics accelerator and 4 GB of RAM. The battery here is lithium-polymer, 3750 mAh capacity is enough for an average of 5 hours of active game.
over, the phone supports GPU Turbo technology. It, according to the developers, provides a performance increase in games of up to 60%, and reduces power consumption by a third.
Playing on your smartphone while charging
For a half-hour test, we took the most demanding titles in terms of hardware. Asphalt 9 and PlayerUnknown’s Battlegrounds.
Asphalt 9. In the first 15 minutes, the temperature reached 40 degrees, after which it only occasionally rose by a degree and still came back. The heating was felt by hands, but only in the upper part of the device, that is, opposite to the charging socket. Where the processor resides, not the battery.
Playerunknown’s Battlegrounds. The action movie is famous for the increased load on the CPU and GPU, so its launch caused some concerns. Nevertheless, Honor Play coped with such a load with dignity: the temperature at its peak reached 44 degrees Celsius, and the average stable indicator was 42-43 degrees. The device has warmed up where the processor is located, not the battery. Obviously, the aluminum case does an excellent job with the heat sink and does NOT allow the iron to overheat.
In both cases, no throttling was observed, the gadget maintained a stable FPS level, do not let it gray. There is no need to speak about any brakes, bugs, and even more the shutdown of the device caused by temperature.
What is the problem
Fears about the flaming case are easy to understand: they say that iron during gaming is already heating up not weakly, and then heating from the current coming from the mains is added. The operating temperature range of the lithium-based battery found in many smartphones is 20 to 50 degrees Celsius. The standard heating of the gadget when Zaruba in top titles is about 35-40 degrees.
Typical lithium-ion battery
For lithium batteries, mobile electronics were equipped with nickel-based batteries. They had a wider operating temperature range (from 40 to 60 degrees), but were bulky and withstand fewer charge-discharge cycles. For the greatest efficiency, they had to be discharged to zero a couple of times at the beginning of operation, and then repeated the procedure every 2-3 months. Lithium batteries do NOT require such care.
Today the autonomy of smartphones does not actually change, but one should not think that batteries are NOT improving in any way. Engineers pay attention to safety, especially in the context of fast charging and the trend (already, however, not too relevant) to reduce the size of devices. And speech Not only in battery tests in production (remember in every sense the bombing story of one Korean brand?). The gradual transition from lithium-ion batteries to lithium-polymer also affects. The latter are distinguished by their increased capacity with the same dimensions and a large number of charge-discharge cycles.
Lithium polymer battery
Today, not only the technology of producing batteries for gadgets is being improved, but also their testing. Any self-respecting vendor conducts a number of safety tests, which include live load and overheating, to make sure that the smartphone will not smoke, even if the user runs the most advanced games while charging. However, trust, but verify. Therefore, we take a mobile phone, connect it to an outlet and run resource-intensive applications.
Can I play while charging: we check empirically
There is nothing worse for a mobile gamer than a phone that is about to run out of power during the most intense moments of the game. Even if you manage to reach an outlet or an external battery, the question arises: is it possible to continue Zaruba while charging? Indeed, in resource-intensive hits like PUBG, the case heats up decently, the battery theoretically can go bang. Or not? Let’s take a chance with the editorial Honor Play and actually find out if there are many chances of being left without a smartphone, playing while charging.
You can play on a modern smartphone while charging. Of course, we have tested this statement only on one model, but again: every self-respecting vendor cares about security. Of course, do not forget the obvious: while gaming, the phone will take much longer to charge. So the question is about convenience. after all, you can endure half an hour (fast charging after all) in order to continue playing for your pleasure without wires.
Should I always keep my laptop on charge?
If you look for the answer to this question on thematic forums, you can find that there are only three main opinions on this matter:
- A permanently connected charger does not in any way affect the operation of the laptop and the battery life
- Continuous recharging can lead to overheating of the device and premature battery failure.
- It is best to remove the battery from the device altogether, and insert it only if necessary, mainly using a laptop as a desktop computer
Reference! These tips were really relevant for the batteries of the previous generation, but now their use is unlikely to be justified.
In the majority of modern mobile equipment, so-called lithium-ion batteries are used, which are characterized by an increased service life and a low self-discharge level. Such batteries are disconnected from recharging when they accumulate the maximum possible amount of energy, and resume charging when the charge falls below the set level.
However, lithium-ion batteries are not perfect and have their drawbacks. For example, they gradually lose in terms of energy consumption after each recharge cycle. Over a long period of time, this significantly affects the state of the battery, therefore, over time, many owners of modern mobile technology begin to notice that their device ceases to “hold” a charge.
Advice! In order to extend the service life of such a battery, some experts advise making it full (before disconnecting) charge about once a month, and the rest of the time to make its periodic recharging.
Is it possible to keep the laptop constantly on charge
In fact, every laptop user at least once asked questions about how long a laptop can be kept on charge, and whether it is worth removing the charger plug from the connector when the battery is fully charged. The opinions of users on the Internet on this topic were usually divided, and on the vastness of the network among laptop users serious disputes flared up about the features of laptop batteries. This article aims to dot the i’s in the above question.
How to properly charge your laptop: recommendations
Not many laptop users know that most of their models have a so-called power saving mode, which allows you to extend the battery life. This mode, however, has a significant drawback: when it is turned on, a special controller does NOT allow the battery to work at full capacity, and limits the maximum possible charge by about 80%.
If we are talking about buying a new laptop, before turning it on for the first time, it is recommended to charge it “one hundred percent”, that is, wait until the battery is fully charged, even if it takes a long time. In addition, after the first start-up, it is recommended to completely discharge the battery and charge it three times. Do not leave the battery discharged for a long time. At the same time, in the “cycles” of discharging / charging, it is recommended to give the laptop an average level of load, that is, DO NOT play “heavy” games and do not watch full-length movies from external media.
It will also not be superfluous to study the technical documentation with which the developer has completed his product. Often, it contains general information about the nuances of setting energy consumption “for yourself”, which allows the user to choose the optimal load and maximum charge parameters for the device.
Reference! Experts do NOT recommend leaving the laptop uncharged for a long time. In this case, the concept of “discharged” includes not only a completely dead battery, but also a battery with a charge level of less than 10%.
It is also worth avoiding long periods of inactivity of the laptop in the off state, fully charged and with the charger connected to it. It is also not recommended to keep the laptop in sleep mode for a long time, since such a mode, contrary to popular belief, nevertheless consumes electricity, and, moreover, very quickly. In order to slightly reduce the rate of battery discharge, you can not only select the power-saving mode, thus reducing system performance, but also reduce the brightness of the display through the system settings.
