iPhone Doesn’t Show Battery Usage Statistics. Top 2 Reasons!

Hello everyone! How can you estimate the state of your iPhone battery? Well, if you need more or less accurate data, then for this you can use special programs that show all the information about the battery. And although they will provide information “in full”, it is not always convenient. it takes a long time, and you don’t always want to make unnecessary gestures to install utilities.

It’s much easier to open the settings of your iPhone, go to the “Battery” section and see the usage and standby times there. Easier, but not always In some cases, this very statistics will simply not be displayed there. instead of the required data on the device’s operating time in hours and minutes, you can see an empty space (to be more precise, there will be two dashes).

Let’s figure out what these cases are and what can be done to return the display of battery usage statistics in the settings of your iPhone. Let’s go!

Before the main “analysis”, it is nevertheless necessary to note such a very simple point. Inscription in settings:

Usage statistics will appear after iPhone is fully charged.

Indicates that usage statistics will appear when the iPhone battery is fully charged. Logic! 🙂 If this is the only problem, then all you need is just to charge the device to 100%.

Cause Deficiencies in the operating system

Yes, despite the huge number of versions of this operating system, this happens. Elementary iOS glitches. How to return the display of the usage time and wait statistics in this case:

  • Restore the firmware. The procedure is very simple, but to be sure, it is worth entering the gadget into the DFU state before doing this. And yes, there is no need to restore a backup. watch whether the data is shown on a “clean” device.
  • If you don’t have a computer and iTunes at hand, a simple reset of settings and content can help.
  • Install the public beta firmware. This is a special version of iOS that is always slightly newer than the one currently installed on your device. Perhaps, it is in her that a similar “bug” with the display has already been fixed. Although, you should be careful, since the beta version of the firmware is not “final”. in some cases, you can find other flaws in it.
  • Wait for the official iOS update. as a rule, new software versions take into account and fix errors of older versions (not always).

Cause Battery replacement

Yes, it is not always Apple itself and its iOS operating system to blame for the lack of data on latency and battery usage in the settings. Sometimes, this happens after changing the battery.

The fact is that, as a rule, almost all batteries sold in the vastness of our homeland (and abroad) are not original batteries. Apple brings to Russia original spare parts only for its service centers. And they go exclusively to repair warranty devices. In any case, the technical support assured me of this.

Although, on the other hand, we know that in most cases, when applying for warranty from an iPhone, it is the device replacement, not repair, that occurs. Then why do they import the original batteries separately? Unclear.

Well, that’s their business. We will return to the problems with displaying statistics. So, these very problems often occur due to the fact that the replaced battery is not original. And, in simple terms, it is not perceived by the system. it simply cannot “read” and show data on the waiting time (use). What to do in this case?

Almost everything is the same as in the previous subheading. The two most effective methods are:

  • Firmware recovery. It is advisable to perform after replacing the battery, even if there are no visible problems.
  • Wait for the new iOS version and update.

Here’s everything a user can do. Of course, there is one more option. you can change the battery again. But no one gives a guarantee that after this procedure the operating time in the settings will be shown “as it should”. Therefore, in my opinion, if everything else works well, then you should not “throw out” money for a new battery.

How to check iPhone battery health?

At the moment, a modern smartphone is primarily judged by two criteria: the camera and how long the battery lasts. The first moment improves from year to year, but with batteries it is problematic, especially on the iPhone.

After all, literally after a couple of years of use, the operating time of the device is reduced very significantly and you already need to think that you need to do something about this. This is especially felt by people who live in countries with cold winters.

Therefore, let’s figure out exactly when it is worth changing and how to check the condition of your iPhone battery. With some updates to the operating system, it is much easier than it used to be.

How to check iPhone battery status?

If you went to this material, then surely your iPhone does not hold a charge for long and you charge it at least twice a day. Or, it often turns off in the cold at the most inconvenient moment, even when the charge level is about 40%.

To understand how bad everything is and whether it is worth worrying about a replacement, you just need to carry out one of the actions, which I will now list.


Checking with built-in iOS functions

On March 29, 2018, the long-awaited iOS 11.3 update was released. Along with it came a feature that was associated with the scandal over the slowdown of old iPhones.

So if you have already installed iOS 11.3, then we do the following:

  • open Settings and scroll down until we find the Battery;
  • select the item Battery status;
  • we see the Maximum capacity field and if you have at least 60%, then you can relax for now, but already think about replacing in the near future.

Settings. Battery. Battery status. Maximum capacity

You’ve probably seen the second field “Peak Performance” as well. So, when everything is really bad with your battery, the phone will send you a notification that an understatement of performance is turned on.

This, in fact, will be the bell for replacing the battery. Thus, Apple killed all the applications that did the status check function, but they may still come in handy. Read on.

Check with third-party programs (if iOS is lower than iOS 11.3)

Not everyone wants to upgrade from iOS 10 to their old iPhone 5S or iPhone 6 for this feature. We all know how it works and it is better to stay on an older version of the operating system.

Sooner or later, you may still need to check the status of the battery, and in this case, we do the following:

  • install ourselves an application like Battery Life (or something similar);
  • we open it and the state of your battery is written to you.

If everything is fine, it will simply say “Excellent” and the button will be green. Yellow, still not so bad and red. when to change.

It weighs a little and is free. If you buy a paid version, it will also show the number of charging cycles. But it’s up to you to decide.

Battery Pro (for iOS)

The mobile application looks ugly and does not differ in the accuracy of measurements. It claims my iPhone battery is in perfect condition. 0.0% wear.

At the same time, it determines the residual capacity at the level of 2000/2000 mAh (remember, in general, in the iPhone 7. 1950 mAh).

In addition, there is data on the source of the charge, which is similar to the truth, determining the operating time of the device and other additional information.

Recommend using this app only, if you don’t have a Mac at hand for more accurate tests.

How to check iPhone battery wear%. How many do you have?

After a wave of controversial opinions from readers about Eduard Sargsyan’s collection of tips on how to extend the battery life of an iPhone, I checked the wear of my.

For 163 days after activation and 140 full charge-discharge cycles, the state of the battery of my 7 is excellent. And the capacity reaches 98% of the declared.

  • I charge my iPhone with iPad charging 95% of the time
  • I keep my smartphone connected to Mac for a couple of hours daily
  • always I connect it to the charger for the whole night
  • used the dubious Lightning of the Rock company (they just fell apart in a couple of months), and today he preferred Native Union (like MFi, quality at 5)
  • I put my iPhone in Xiaomi power banks and auto-chargers (I think it’s okay here)
  • I do not follow the temperature regime from the word at all (summer and a regular beach are ahead)

iBackupBot (for Windows)

The data of this “scary” application, which I recommend to Windows users for lack of coconut Battery, does not match the previous ones.

This is strange. they generally claim that I can charge the iPhone up to 2000 mAh out of 1950 possible. But I suggest taking this as the ideal state of the battery.

Information can be accessed from the Information menu. Look at DesignCapacity is the stated capacity, FullChargeCapacity is the state of the battery today.

coconut Battery (for macOS)

In my opinion, this is the best application for determining the level of wear of the iPhone battery, which can be found on the iOS Device tab.

Here you can see the number of complete charge-discharge cycles (after 500, experts recommend changing the battery), residual capacity (look at Maximum Charge) and other data.

Based on this information, I am guided about the consequences of my “bad habits” of handling the iPhone. lowered the level to 98%.

This application is also interesting for diagnosing the MacBook battery. for a year and a half of super-intensive use, I “killed” mine up to 92% of the declared capacity.


In almost half a year of intensive use, two out of three tests indicate the perfect condition of the battery of my iPhone 7, and one about a drop in capacity by 2%.

On this occasion, in order to put everything in its place, I propose a small interactive: let’s all together check the iPhone batteries and talk about their wear and tear and our “bad habits” in the Комментарии и мнения владельцев.

Thus, we will decide once and for all whether it makes sense to charge your smartphone with care. Or you can just use it and have fun.

UPD: There is a possibility that the software used in the article does not have access to information about the iPhone 7 / Plus battery.

Checking iPhone battery wear

To make your smartphone battery last longer, you need to follow simple guidelines that will significantly reduce wear and tear and extend the lifespan. And to find out how rationally to use the old battery in the iPhone, there are two ways: using standard iPhone tools or using a computer program.

IPhone Standard Tools

IOS 12 introduces a new feature in testing that allows you to see the current state of the battery.

  • Go to “Battery Status”.
  • In the menu that opens, you will see the “Maximum capacity” column, which indicates the state of the phone’s battery. In case you see a reading of 100%, the battery has the maximum capacity. Over time, this indicator will decline. For example, in our example, it is 81%. this means that over time the capacity has decreased by 19%, therefore, the device has to be charged a little more often. If this indicator drops to 60% and below, it is strongly recommended to replace the phone battery.
  • How to check battery wear on iPhone


    IBackupBot is a special iTunes add-on that allows you to manage iPhone files. Of the additional capabilities of this tool, the section for viewing the status of the iPhone battery should be noted.

    Please note that iTunes must be installed on your computer for iBackupBot to work.

    • Download the iBackupBot program from the developer’s official website and install it on your computer.
    • Connect iPhone to computer with USB cable and then launch iBackupBot. The smartphone menu will be displayed in the left part of the window, in which you should select the “iPhone” item. A window with information about the phone will appear on the right. To get information about the battery status, click on the “Information” button.
  • A new window will appear on the screen, in the upper part of which we are interested in the “Battery” block. It contains the following indicators:
  • CycleCount. This indicator means the number of complete charging cycles of the smartphone;
  • DesignCapacity. Initial battery capacity;
  • FullChargeCapacity. Actual battery capacity based on wear.
  • Thus, if the indicators “DesignCapacity” and “FullChargeCapacity” are close in value, the smartphone’s battery is normal. But if these numbers are very different, you should think about replacing the battery with a new one.

    Any of the two methods given in the article will give you comprehensive information about the condition of your battery.

    When to change your iPhone battery

    However, it is very important to know exactly when your smartphone needs an immediate battery replacement. To do this, you can:

    a. contact a specialized Apple service center in which you will be diagnosed with the device (data from the center will be more accurate);

    b. check the health of the battery yourself. But, please note that in the second case, the data may be less accurate.

    In order to check if your iPhone needs a battery replacement, you need to:

    • Unlock your iPhone
    • Go to the “Settings” application
    • Go to the “Battery” tab
    • Open the “Battery Status” tab

    The first indicator is percent.

    As we wrote above, the smaller it is, the more likely it is that your device needs a battery replacement. Critical percentages are from 50% and below.

    Second indicator. peak battery performance.

    If your iPhone does not need to replace the battery and the system is working properly, then you should see a message: “Your battery is currently maintaining normal peak performance.”.

    You may also see the message: “This iPhone shut down unexpectedly because the Battery was unable to provide the required peak power. Performance management was applied to help prevent this from happening again. ” In this case, you will need to click the “Disable” button to return your device to normal operation.

    If a poor-quality battery was installed on your iPhone, the system will notify you about this with the message: “Could not determine the battery status.” It may work, but you need to be very careful and go through diagnostics to determine where your iPhone’s battery is vulnerable.

    The third indicator is warning.

    In the same “Peak battery performance” tab, a warning about battery damage may appear. this is a direct signal to look for a service center that is able to perform a quality replacement of your device’s battery.

    The fourth indicator is a drop in the maximum screen brightness.

    If you notice that the screen of your iPhone has become noticeably dimmer, but you have not changed anything in the settings, then it is worthwhile to diagnose your battery. This is one of the small, but no less alarming signals.

    Fifth indicator. lower speaker volume.

    A small speaker volume test will also help you check if you should consider changing the battery.

    Sixth indicator. “bugs” of the screen when scrolling.

    Try to quickly scroll through a long article in your browser or gallery. If you notice “braking” while scrolling, then you should also think about how to conduct additional diagnostics of the iPhone.

    Indicator seventh. lower frame rate in some applications.

    Almost the same as scrolling bugs. Noticed that in the game, the display of the picture starts to slow down, which was not there before, then you have a direct path to the workshop to check the battery.

    Indicator eighth. longer application startup time.

    Another indirect indicator that can give out premature damage to the battery and a decrease in its performance. If you notice that applications take longer than usual to start, check the battery. But, when doing this test, you need to make sure that there are not too many applications open in the tabs, otherwise the problem may be completely different.

    Why iPhone Battery Stops Working

    Like any thing, the battery of your iPhone cannot last forever and over time it needs diagnostics, and sometimes replacement. But why in some users the iPhone battery can work harmoniously for 5-6 years, while in others it can stop working six months after the purchase of an “apple” device? It’s all about how the device was handled, how often it was charged (and whether it was done correctly), as well as whether it fell, was not “drowned” and much more.

    100% Easy Way to Fix No Battery Health Shows on Iphone 6 #MarkTechTips #CubarGadgetRepair

    IPhone battery is suspected to be unusable after 500 full charges, even if you have followed all safety precautions and instructions. Unfortunately, iOS doesn’t keep track of how many times your device’s battery has been charged. In addition, each iPhone has a special feature that puts your device into a lower power mode when the battery starts to “junk”, so very often older Apple devices can slow down, glitch and turn off more often than the same models just purchased.

    But, nevertheless, there is a way to test the health of this component of your iPhone and determine if it needs immediate replacement.

    How to check iPhone battery health

    What to do to check the status of the iPhone battery, identify a malfunction or poor quality of the battery of your iPhone, and also how to act if you are going to change the battery on your device, we will tell in this article.

    Has your iPhone started to slow down, run out of power faster than usual, or just shut down for no apparent reason? It may be worth considering replacing the battery on your iPhone, as it will wear out and lose its ability to serve you well over time. In order to be sure that you need to immediately contact a service center, it will be useful to know about a function that will help track the normal life cycle of your iPhone battery, which we will discuss in this article.

    For a professional assessment of the condition of your iPhone’s battery, you can contact the iLab service center.

    How to check iPhone battery health

    In fact, it is very easy to check if your battery needs a replacement, because at the beginning of 2018 Apple released a special addition to the iOS settings, where you can understand in a few steps: is it worth considering buying a new battery for iPhone.

    In order to check the health of your iPhone battery, you need to:

    • Unlock your device
    • Open the Settings app
    • Go to the “Battery” tab
    • Then click on the link “Battery status”
    • View the percentage of your “Maximum Capacity” versus a new one. If it is less than 50%, then you should think about changing the battery.

    What to do if your iPhone battery is faulty

    And then just ask the wizard for help. But don’t talk about replacing the battery right away. Ask for diagnostics in one service, in another. If the alarming data is confirmed. then already contact us with a request to replace the battery on your iPhone.

    Battery Check Using iBackupBot Windows Program

    If you would like to know more about your iPhone’s battery wear and tear, you can use desktop PC software. There is a program for the Windows operating system called iBackupBot. It is paid and costs 35 dollars, but during the first 7 days you can use it for free.

    In order to check the level of battery wear using iBackupBot, start it on your computer and connect the iPhone using a cable. After that, you need to wait a little while the program detects the device and creates its profile. When the device is detected, pay attention to the left side of the window and select your iPhone here.

    Then open the section “Information”.

    As a result, you will see information about the level of wear on the battery of your iPhone. There will be many parameters here, the most important of which we will consider separately.

    • CycleCount. the number of charging and discharging cycles of the battery;
    • DesignCapacity. Initial battery capacity;
    • FullChargeCapacity Current battery capacity.

    The number of charging and discharging cycles of the battery is another very important parameter that speaks about the deterioration of the battery. The more cycles the battery has passed, the worse its condition. If your battery has more than 500 cycles, then it’s time to think about replacing it.

    Checking Battery Wear Using iOS Apps

    For example, you can use the Battery Life app. After launching this application, you will see the percentage of wear on your battery, as estimated by the application. In the screenshot below, that’s 87 percent.

    If you wish, you can see more detailed information about the battery of your iPhone. To do this, click on the button in the upper left corner of the screen and go to the “Raw Data” section.

    Here you will see two options: Capacity and Battery Charge. The Battery Charge setting is just the current charge level of your iPhone, it’s not interesting. But the “Capacity” parameter is more interesting. It shows the current capacity of your battery (in the screenshot it is 2400 mAh) and the initial capacity of your battery (in the screenshot it is 2750 mAh).

    It is the difference between these values ​​that is calculated as a percentage. The greater the difference between the current and the original capacity, the worse the battery condition.

    How to check battery wear level on iPhone

    IPhone settings can be used to find out the battery life and which apps are draining the device’s battery the most. But, in the settings there is no information about the state of the iPhone battery and what level of wear it has.

    Fortunately, this information can be obtained using third-party applications and programs. In this post, we are going to show you how to check battery wear on iPhone using iOS apps and programs for Windows and macOS. Information will be relevant for all iPhone models, iPhone including 4, 4s, 5, 5s, se, 6, 6s, 7, 8 and iPhone X.

    Checking the battery using macOS CoconutBattery

    If you have a macOS computer, you can check battery wear using the CoconutBattery program. The main purpose of this program is to view information about the MacBook battery, but it can also provide information about connected iOS devices (iPhone, iPad, etc.).

    READ  How to untie Apple Watch from iPhone

    In order to use this method of checking the battery, simply connect the iPhone to your computer, run the CoconutBattery program and go to the “iOS Device” section.

    As a result, you will see a screen with information about the iPhone battery. This will show the current battery level (Current Charge), maximum battery capacity (Full Charge Capacity), initial battery capacity (Design capacity), the number of battery charging cycles (Cycle Count), and other parameters.

    As you can see, the amount of information here is almost the same as in the iBackupBot program.

    How to calibrate iPhone battery and why you need it?

    Hello everyone! The iPhone has a lithium-ion battery, and these batteries are not known to have a memory effect. Then why calibrate them at all? The fact is that the capacity of the battery drops over time (how to check its current state) and if you have had the phone for a long time, then in the absence of battery calibration, strange things begin

    It happens that the iPhone “does not understand” what the current battery capacity is and cannot correctly display information about the battery charge level. As a result, various non-standard situations occur: an unexpected shutdown by 20-30%, freezing of the charging indicator (long display of one value), incorrect data is shown about how charged the iPhone is and other disgrace.

    By the way, although in this article I write everywhere about the iPhone, this method of battery calibration is great for other Apple equipment: iPad and iPod.

    But first, let’s summarize the signs that clearly indicate that the iPhone battery needs to be calibrated.

    • iPhone shuts down when there is still charge percentage. It would seem that he still has to work and work, but he bam and turned off.
    • In some cases, calibration will help those users who run out of battery very quickly. True, this is just one of the methods of dealing with an instantly discharging smartphone.
    • If the iPhone freezes for a long time at one percent of the charge, and then the indicator sharply “jumps” by several tens of percent.
    • It is advisable to perform calibration every 2-3 months for absolutely all iPhone and iPad users. If you’ve never done it, now is the time!

    At least one of the described cases is your situation?

    Then read on and learn how to properly calibrate the iPhone battery.!

    • Wait until the device is completely discharged. It is entirely and completely (absolutely, “to zero”, so that it is not included at all).
    • We put it on charge (preferably from the network) and do not touch it (of course, you can answer an urgent call, but you do not need to play and use). We wait until it is charged to 100%.
    • We leave connected for another hour or two. What for? For reliability! After all, the iPhone does not show charging correctly? Wrong! So, you can’t trust him. And despite the fact that the screen displays 100% charge, the battery may not be fully charged! Therefore, to be sure, after reaching 100%, we do not turn off the plug immediately, but wait at least another hour.
    • Disconnect from the network and do a hard reboot. To do this, press and hold two keys. Home and Power on, until the apple icon lights up on the screen. Updated! This combination of buttons does not work for all devices. How to be? Here is a detailed instruction on how to Hard Reset any iPhone.!
    • We use the device until it is completely discharged.
    • We repeat this procedure 2-3 times.

    As you can see, there is nothing super complicated. And the only “narrow” moment is time.

    But there’s nothing you can do about it, battery calibration is not a quick thing.

    Important! When you start doing the second loop, you do not need to recharge your iPhone for a short time! The circuit should be exactly like this. from 100% to 0%, then to full charge without interruption, charged, hard reset and discharged to 0% without recharging.

    Only then will the calibration be truly correct and will benefit your iPhone’s battery.

    Checking iPhone battery health

    The first thing to start our article with is to identify the iPhone models that are compatible with the new iOS 11.3. The updated “axis” works with models starting from the iPhone 6 and older. If your device meets the declared specifications, then you can read on. And if you are the lucky owner of the “six”, then we recommend that you postpone the update to a newer firmware. Usually the minimum declared model for a new firmware, it works extremely hard with new software, it can slow down a little or “dull”.

    So, information about the state of the battery in your iPhone is located in the following menu: “Settings” “Battery” “Battery status (beta)”. In the window that opens, all information about the battery of your iPhone will be indicated.

    Battery Health (Beta) for iOS 11.3.

    IPhone battery in normal condition

    If the battery condition in your iPhone is excellent, then by default the system will not activate the lower performance function automatically, but will only write the following message on the screen:


    The battery in your iPhone is OK

    In this case, we can congratulate you. everything is OK with the phone! You can continue to use your iPhone as usual.

    When the iPhone battery is worn out

    If, after updating to iOS 11.3, your iPhone at least once spontaneously turned off or rebooted, this may indicate that the battery can no longer provide full power and will soon have to be replaced. After rebooting and turning on the iPhone, it automatically activates the performance reduction mode at high (peak) loads and displays the following message on the smartphone screen:


    Reduced Performance Mode Warnings

    If you are against low performance on your iPhone, you must turn off this feature yourself in Settings. Also note that this function will automatically turn on after each involuntary shutdown or restart of the iPhone. Thereby reminding you to replace the iPhone battery.

    If you ignore these system warnings for a long time, then soon iOS will simply ask you to replace the battery with a new one, displaying the following message on the screen:


    When this message appears, we strongly recommend that you immediately contact the nearest service center to replace the battery. If you don’t, the problem can get worse and damage other parts of your phone.

    Also, the following factors can negatively affect the state of the battery:

    • Poor charging cord;
    • Non-original block;
    • Permanent battery discharge “to zero”;
    • Operational wear.

    The new function will also be useful when replacing the battery, because now it is able to recognize low-quality batteries. If after replacing the battery at a service center, the following message appears on the screen:


    Most likely you have a poor quality battery installed. And it is better to immediately ask such a service to replace the part with a better one, in order to avoid further troubles.

    The FixLab network of service centers will help you with replacing the battery in any iPhone. You will be offered two options for the best quality batteries. The first is a High Copy type battery with a 1 month warranty from our service. The second are rechargeable batteries of similar quality to the original with a 3-month warranty! Everyone can choose a more suitable option for themselves. With for the service “Replacing the iPhone Battery” can be found on HERE.

    In August 2019, Apple released another iOS 12.4 update, one of the innovations of which was the restriction on replacing the battery in all iPhone models at unauthorized service centers.

    Now after replacing the battery (regardless of its quality and manufacturer) at an unauthorized service center BATTERY WEAR PERCENTAGE WILL NOT BE DISPLAYED. Technically, it was possible to implement this thanks to the unique serial number of the controller installed on each battery for the iPhone. The system checks it against its database and if the numbers do not match, it blocks this function.


    This is how it looks on the iPhone 7 Plus screen

    The Cupertino-based company itself attributes this innovation to concern for the safety of users and to protect them from poor-quality repairs and the installation of counterfeit batteries. Also, Apple noted that this “innovation” does not affect the operation of the iPhone in any way.

    Apple has already been heavily criticized for this decision, accusing it of wanting to monopolize the market for repair and maintenance of smartphones, as well as the desire to receive super-profits. Several lawsuits are already being prepared in the USA.

    The situation may change with the release of iOS 13, which will be presented in September.

    Why is it important to check battery health

    The check is needed specifically in order to understand whether a battery replacement is needed in your case or not. If his condition is good, replacement is not necessary. Quick discharge in this case is facilitated by the work of a large number of applications. just use only the most necessary programs, and close the rest in time. Also turn off “Wi-Fi” if you do not need it at the moment.

    It is better, of course, to check the degree of deterioration of the battery regularly. this way you will begin to take care of it more carefully, follow the charging rules in order to delay the need to replace it.

    Built-in tools

    The iOS 12 variant has an option to check the battery status. If your version of “operating system” is lower than 12, the method is not suitable for you.

    What settings to go to to find out the exact percentage of wear:

    • Open the panel with sections of settings. Click on “Battery”.

    Expand the beta “Battery Status”. You will immediately see the maximum current battery capacity. If you have 100%, then everything is fine with your battery so far. If you have 80%, then the volume has already decreased by 20%. If the indicator reaches 60. 50%, you need to think about changing the battery.

    How to check battery health on iPhone and iPad

    You can find out for sure how much is left in your battery from the factory capacity using standard iOS tools or using a third-party utility that is downloaded to a computer with Windows or Mac OS.

    The immortal iPhone: how to determine the current battery wear on your device

    Regardless of how high-quality your iPhone battery is, this is just a consumable for the device. Over time, the capacity of the battery will inevitably decrease anyway. How to check the current state of your battery?

    iPhone not responding to charging: finding and fixing the causes

    Expert thoughts on how to properly charge your iPhone

    So, technician Eric Leamer found that charging the iPhone battery too often can cause some damage to it, and also, he found that you cannot often charge the battery to 100%. In other words, it is enough to fully charge your phone once a month, despite the fact that the frequency between successive charging processes should not be less than one day.

    If possible, if you do not use your phone heavily throughout the day, it is recommended to keep its charge level at about 50%. In general, the optimal charge level is considered to be 40-80%. Why is it not recommended to fully charge your iPhone 4S? There is a simple explanation for this.

    READ  Camera on iPhone locked screen

    If you charge the phone, for example, to 50%, then the lithium-ion battery will be charged to a certain voltage. If the percentage of charge is increased, the voltage will also increase. Accordingly, the more each battery cell stores voltages in itself, the faster a certain cell and the battery itself will wear out in general.

    What is the threat of great stress? By reducing possible charge / discharge cycles. The same researcher confidently stated that by charging the iPhone constantly at 100%, your smartphone will be able to perform approximately 300-500 charge / discharge cycles. At the same time, if the iPhone is charged only 70%, the number of cycles will increase to 1200-2000. As you can see, the result is simply impressive.

    Also, Eric noted that you should not resort to unreasonable methods. For example, some people believe that having bought a phone with a new battery, it will need to be “run away”, that is, it will need to be charged for 72 hours. This tip only applies to nickel batteries, but iPhone 4S uses lithium-ion batteries like all other models.

    Maintaining good battery health

    To keep your iPhone battery healthy, it needs electrons to move frequently. In other words, the correct state of the battery is when it is discharged for a while and then recharged. over, its charge level should fluctuate around 40-80%.

    If you perform such a slightly inconvenient procedure, you can increase not only the number of cycles, but also leave the same capacity indicator for a long time. This kind of exercise can be called truly correct.

    Turn on Power Saving on iPhone

    Why does the battery lose its capacity?

    If you use your iPhone in extremely low or high temperatures, then its battery will start to behave badly after a certain time. For example, the optimal temperature for using a phone is 15 ° C.

    If the temperature rises by only 10 ° C, your battery will lose about 20% of its capacity per year; if the temperature rises by 20 ° C, the battery capacity will drop by about 35% per year. Because of this reaction to rising (as well as falling) temperatures, we strongly recommend that you avoid wireless inductive chargers that generate too much excess heat when charging.

    Actually, now you know how to charge your phone with maximum efficiency, and in order to further extend the life of the battery, you can save power by turning off applications and lowering the brightness, or by using “Airplane mode” if you are in regions where the connection quality is very poor or even absent.

    Learning how to properly charge your iPhone

    If you are the proud owner of an iPhone 4S or any other, then you probably faced the problem of the need to frequently charge the device. We can say that charging your iPhone for many is something like brushing your teeth in the morning.

    Some more “extreme” people prefer to charge the iPhone only after it is completely discharged, while others put it on charge as soon as possible. But be that as it may, everyone, without exception, wants the battery of their smartphone to serve as long and productive as possible.

    In case you do not know for sure how to properly charge your iPhone, we suggest you read the opinion of the pros on this matter.

    As a result, calibration will not help you, but there are some tips:

    ▪️ Do not try to revive a dead battery, replace it instead if it does not already show “Peak performance” in the “Settings” “Battery” “Battery status”.

    ▪️ Don’t trust third party battery testing software. Connect iPhone to Mac and turn on the famous coconutBattery: the values ​​in it are constantly changing, so it blatantly lies.

    ▪️ Follow the rules for using the iPhone: update iOS, use normal accessories, monitor the critical temperature and charge level when storing your smartphone.

    On this topic, with the calibration of the iPhone battery, I propose to consider it closed. Of course, I will be happy to hear any counterarguments, but I doubt that there will be such.

    IPhone battery controllers keep track of them securely

    How the controller controls iPhone charging

    iPhone has excellent control over the charging of its battery, which takes place in two stages: charging in fast mode and trickle charge mode.

    ▪️ Charging in fast mode. First, the iPhone loads its battery as much as possible and brings the energy inside it to 80%.

    Charging times vary depending on the power source you are using: Standard PSU, iPad PSU, Power Delivery Mode with MacBook PSU and Lightning to USB-C Cable.

    At the same time, the controller monitors the temperature and reduces the charging speed if it reaches critical values.

    ▪️ Trickle charge mode. The remaining 20% ​​of the battery is charged at reduced amperage, and the energy level inside it reaches 100% gradually.

    This is necessary so that the battery is worn out as little as possible. Therefore, even my iPhone 7 with 750 recharge cycles today feels quite normal and even shows “Peak Performance” of the battery.

    Wasted time. Battery performance unchanged

    The program shows changes, but they are not really there

    Before starting the procedure, I recorded the values ​​in coconutBattery: the battery state is about 83%, the maximum capacity is 1631 out of 1960 mAh.

    After the procedure, the numbers in the application really increased: the state of the battery is about 88%, the maximum capacity is 1724 out of 1960 mAh.

    It would seem that it’s time to clap your hands and run to write the most positive conclusions.

    Does Your iPhone Need a New Battery ? Find out

    But instead, I began to observe the data that coconutBattery produces for a couple of minutes.

    The miracle app surprised me: the battery health percentages jumped by different values ​​in the range of 80-90%. Therefore, there can be no question of any accuracy in this case.

    Instead, I will use a more realistic source of information that can be trusted. “Battery Status” from the “Settings” “Battery” menu:

    And it was, and there are 87%.

    The maximum battery capacity is 87%, it was the same before the experiment and remained the same after it.

    This confirms two facts:

    ▪️ There is no point in calibrating the iPhone battery. we’ll see this a couple of times later. ▪️ Third-party apps do not have access to real iPhone battery data.

    If you are not satisfied with the battery life of your iPhone, and the number of its recharge cycles has exceeded 500, replace the battery

    Humble yourself, this is a consumable, and it gradually breaks down every second.

    When to Change Your Favorite iPhone Battery

    500 cycles is not always the limit

    Apple recommends changing the battery after 500 charge cycles. During this time, his condition usually falls below 80%, and then the rate of his degradation grows exponentially.

    But I have in my hands a vivid example of a relatively careful attitude to the device: iPhone 7 with 750 charge cycles and 87% battery status.

    I do not do anything supernatural, but I hardly break the 5 rules above.

    Apple doesn’t even recommend calibration itself.

    Battery controllers are calibrated during production

    In the past, Apple actually advised to periodically calibrate the batteries of its devices. Most likely, this concept has remained in the minds of experts since then.

    However, this never had anything to do with the iPhone. Device controllers with built-in battery are calibrated during production and do not need any additional manipulations.

    Only devices with a removable battery need to be calibrated: MacBook and MacBook Pro prior to 2009, and iBook and PowerBook.

    tips to make your iPhone battery last longer

    Updating iOS isn’t scary today

    ? Update your iOS sooner. A couple of years ago, Apple was accused of deliberately slowing down the iPhone using new versions of the operating system.

    After that, the company is attentive to updates and regularly optimizes each subsequent.

    iPhone can and should be updated. It is best to turn on “Auto-update” in the “Settings” “General” “Software update”.

    ? Normal accessories. Cables and power supplies of unknown origin are contraindicated for long battery life.

    At the same time, to charge your iPhone, you can safely use the power supply not only from the iPad, but even from the MacBook (we are talking about USB-C).

    High and low temperatures are your enemy

    ? Be afraid of the temperature. iPhone is best charged and used in temperatures between 0 ° C and 35 ° C.

    Any stress load in conditions that go beyond these limits can be harmful to the battery.

    ? Charge without a case. Many models of cases (especially non-names) contribute to overheating of the battery.

    If you notice that iPhone is getting hot while charging, remove the case first.

    ? Store your iPhone properly. If you do not use your iPhone for a long time, keep the energy in its battery at about 50%.

    It is best to check its level once every couple of months.

    Testing the most popular battery revitalization tip

    Experts recommend two steps to calibrate the iPhone battery: a preparatory step and a calibration step.

    First you need to disable resource-intensive tasks

    ️ Preparatory stage. At the preparatory stage, you should disable the most energy-consuming processes on the iPhone. This must be done so that the smartphone does not turn off by 10-20% of the charge, and we managed to discharge it to zero.

    First you need to disable automatic content downloads in the “Settings” menu “iTunes Store and App Store”.

    Next, turn off the background content update in the “Settings” “General” “Content update”.

    After that, you need to turn off geolocation in the “Settings” “Privacy” “Geolocation Services”.

    In the end, it is best to lower the brightness of the iPhone screen to the minimum value.

    A smartphone with a stale battery can turn itself off if there is not enough power, so it is better not to overload it.

    The easiest way to drain your iPhone is with movies

    ️ Calibration phase. At the calibration stage, the iPhone needs to be discharged to full zero and recharged to the maximum level at least a couple of times. For reliability, I did it 3 times.

    ▪️ To discharge the device to zero, the easiest way is to set the video to repeat in VLC and wait until the smartphone turns off.

    After that, it is better to wait a couple more hours for the internal processes to discharge the iPhone to zero. I left the device with the video overnight.

    ▪️ To charge the device for real 100%, you need to connect it to the power supply, wait for the cherished hundred to appear on the indicator, and then wait another couple of hours.

    As with discharging, I left the iPhone on charge overnight so that it could be fully charged.

    I repeated the charging and discharging procedure exactly three times: I completely discharged it during the first night, charged it for the second, and so on.

    To show the result, experts usually use the data of the coconutBattery application.

    I have calibrated my iPhone battery. Did it help or not?

    There are many tips on how to increase the capacity of a tired battery and normalize the display of% charge in iPhone.

    Most often, it is advised to calibrate the smartphone with a series of simple steps. I tested the magic trick on myself and I hasten to share the results.

    The role of the test subject was played by my iPhone 7. The number of charging and discharging cycles has already exceeded 750. According to Apple’s recommendations, the battery in it had to be changed 250 charges back, but it still works quite normally.
