How to check the battery capacity on iphone 6. How to determine the degree of deterioration of the iPhone and iPad
Built-in iOS functions or third-party programs will help you.
As with any mobile device, autonomy is very important for the iPhone and iPad. Every year, user requests are growing, usage scenarios are expanding, and the capabilities of batteries in mobile gadgets remain at the same level due to ever-decreasing thickness and weight.
Complaints about lack exact time battery life You can hear from many users, but how do you know if your device's battery needs replacing or if you're just using it too much? This will be discussed further.
Discharged or not
It will sound trite, but first you need to understand whether the device is discharging itself or you are discharging it. To do this, it is enough just to refrain from active use for a while and observe the level of charge. It is best to fully charge the device and leave it overnight, after taking a screenshot with the charge level at the current time. Don't forget to turn off notifications as well to avoid the possibility of being discharged due to a lot of pushes.
Check the charge level in the morning. If it has not changed or dropped by a couple of percent, then everything is fine with the battery and the accelerated discharge is caused by active use. If the charge has fallen by more than 10% - something is still discharging it. In this case, go to the next item.
Determine the cause of the discharge
We need to determine where the charge is going: is it being “eaten away” by background processes and services, or is the discharge caused by a decrease in battery capacity due to wear and tear. This is quite easy to do through the built-in battery usage statistics feature. Starting with iOS 7.0, we not only have stingy usage and wait numbers (although that's enough), but even detailed app statistics.
The bottom line is that in standby mode, the iPhone and iPad should not be discharged, which means that the waiting time from the statistics menu should be significantly longer than the usage time (despite the fact that the device is at rest).
If your waiting time is equal or almost equal to the usage time, then there is background activity of applications or services, which is the cause of the discharge. It is worth checking the applications from the list and their access to content updates, geolocation and more. Here are some more helpful tips for you.
If everything is in order, and the battery still holds very little even with gentle use, go to the next step.
Testing the battery
Almost certainly the problem lies in the wear and tear of the battery, which is inevitable with prolonged use. During the process of charging and discharging, the capacity of the battery decreases. In the iPhone, it drops to 80% after 500 recharge cycles, the iPad withstands twice as much - 1000. Find out how much the maximum battery capacity on your device has decreased. If the drop is too large and the current autonomy does not suit you, it's time to change the battery.
If your device has been updated to iOS 11.3, then you can find out how much its battery capacity has decreased over the entire period of operation, without additional programs. To do this, open the section "Settings" → "Battery" → "Battery status". The device will show the current value of the maximum capacity as a percentage of the original.
If your device has more than old version iOS, you can check the battery status with free app Battery Life Doctor. Run it and click Details next to Battery Raw Data - in the next menu you will see the Design Capacity parameter (initial maximum capacity). Next to it, the current maximum battery capacity as a percentage of the original will be displayed.
Another way to find out the status of the battery is in iBackupbot for macOS and Windows.
We download the program from the link, open it, connect the device to the computer and click More Information. We are interested in DesignCapacity (initial maximum capacity) and FullChargeCapacity (current maximum capacity). It remains to calculate the difference yourself. If it is too large, consider replacing the battery.
What to do next
75–80% of the factory capacity is not deadly yet, and you can safely live on with this, but if such autonomy is not suitable for your use case, you will have to replace the battery.
It is better to do this in official or trustworthy services. If you decide to replace it yourself, then do not buy suspiciously cheap batteries and keep in mind that unlike the iPhone 4/4s in later devices (and all iPads), the replacement procedure involves complete disassembly device, which requires appropriate skills.
And further. Before leaving for service center try to calibrate the battery. It helps a lot, but trying is not torture.
Not so long ago, Apple gave iOS the ability to control battery consumption. Now some smartphones are slowing down in order to neutralize the possibility of an unexpected shutdown. This is directly related to the wear and tear of the battery of the device, its capacity and the charge-discharge cycles of the device from Apple.
Brief digression: Why and why worn-out batteries “Slow down iPhones”
The tool appeared in iOS 10.2.1 for iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE, as well as in iOS 11.2 for iPhone 7 and iPhone 7 Plus (a significant part of devices)
Apple explained that this tool works, taking into account the temperature of the device, charge, wear level and internal resistance batteries. Thus, your device will slow down only if the characteristics presented require it. If the condition of your battery has deteriorated, and the indicators described above have not been affected, then the device will not slow down.
You can check the battery status using the following four methods, which we have detailed below in the article. We advise you to think about protection iPhone display 6 Plus by choosing the protective glass that suits your needs.
Method 1: coconutBattery app and Mac
Step 1: Connect your smartphone to your Mac. Use Lightning cable MFI;
Step 2. Download and install the coconutBattery app on your iPhone;
According to the information on the official website, there is also an application for iOS. However, we could not find it in App Store. So we used a Mac.
Step 3. Check the condition and wear of the iPhone battery
Click on the iPhone icon. You will immediately see a lot of interesting information regarding your device: the actual battery capacity, the design capacity of the battery, the number of on-off cycles, etc. The percentage under the design capacity (design capacity, highlighted in red in the photo) shows the state of your battery. This is the percentage ratio between the actual (full charge capacity) and the design capacity.
It is important to point out that, according to some users, coconutBattery shows correct data on the level of battery wear until the device is restored. It can be concluded that this is due to a reset.
Method 2: Use Third-Party iPhone Battery Analysis Apps
Step 1: Download the Battery Life app from the App Store
By the way, there you will also find other applications of this kind. You can get the app for free from this iTunes link.
Step 2: Launch Battery Life
On the home page You will immediately see the battery wear level as a percentage, as shown in the image.
The battery capacity of my iPhone 7 Plus, which I bought about a year ago (important: I stopped using it when I switched to the iPhone 8 Plus), has dropped by 10%. For my iPhone 8 Plus and iPhone X, the program showed that their battery condition and wear rate is perfect.
Step 3: Check Raw Data
Click on the hamburger menu at the top and then on Raw Data. This way you will know the capacity of your battery.
The screenshot below shows that the battery capacity of my iPhone 7 Plus is 2,600 mAh, which is slightly less than 90% of the original capacity (it is 2,900 mAh).
Some iPhone users have reported that the app shows the capacity with errors. It is possible that in such a situation, as in the case of coconutBattery, the main culprit is the recent restoration of your iPhone.
Method 3: Console App
Step 1Connect iPhone to Mac
Step 2Launch Console app on Mac
Step 3: Check battery status
Make sure your iPhone is unlocked and that it is trusted by the computer.
In the search field of the Console app, type "batteryhealth". In the column on the left, click on your iPhone. You will immediately see the status of your battery. The app shows that the battery health of my iPhone X is good (BatteryHealth = Good).
Console app works inconsistently. I easily recognized the state iPhone batteries X, however, I was unable to perform the same procedure for the iPhone 7 Plus.
Method 4. Settings App - Exploring iPhone settings
Beginning with iOS versions 10.2.1, Apple issues notices in the section showing battery status that operating system should be diagnosed.
Launch the Settings app and then explore the Battery section. You will find out if the battery needs to be replaced.
Apple representatives also announced that in early 2018 the company will present an update software. Thus, it will be much easier to check the condition of the battery. iPhone users will see if the battery affects the performance of the entire device.
If your iPhone's battery health is below 80% and you're experiencing problems with the device's performance, then you might want to consider replacing the part. By the way, Apple has reduced the cost of replacing the battery to $29.
The iPhone battery is its heart, without it even the newest Apple smartphone— just a useless piece of metal and glass. In this article, we will talk about what kind of battery is installed in the iPhone, how to assess its condition and how to properly charge it.
What type of batteries are in iPhone?
Each iPhone comes with lithium-ion battery. Compared to “traditional” batteries, they have enough advantages: they charge faster, last longer, and weigh less.
Charging the battery consists of two phases. During the first - from 0 to 80% - the battery is replenished with energy quickly (the exact charging time depends on whether the device is used, settings and other factors). The second - from 80 to 100% - is called compensatory, it "weakens" electricity and thereby extending the life of your iPhone battery.
What is a "recharge cycle" and why is it important?
One cycle is when you discharge your iPhone from 100% to zero. This can be done in one go or multiple times. Example: the battery was discharged by 75% in a day. You charged it up to 100% and continued to use it. One charge cycle will end when you use up another 25% of the charge (“yesterday's” 75% + “today's” 25%).
Why are we? At iPhone battery, of course, there is a resource. After 500 full charge cycles, the battery capacity of an "apple" smartphone will decrease by 15-20%. In practice, 500 charge cycles is 1.5-2 years of smartphone operation. After about 3-4 years, the battery capacity will accordingly decrease by 50% of the value that the iPhone had out of the box. That's when it makes sense to think about replacing the battery - after all, you will probably notice that your iPhone, for example, no longer "survives" until the evening and lets you down at the right time.
How to check the number of completed iPhone recharge cycles directly on an iOS device?
Download at iPhone free Battery Life program. Open it and go to the tab Battery, where the value cycles and will indicate the number of recharge cycles passed by the iPhone.
Unfortunately the section cycles in the application battery life available only users of devices with iOS 7, iOS 8 and iOS 9. iOS users 10 and later can get battery percentage data with a general characteristic:
Ideal the battery of the new iPhone.
good- slight loss of capacity.
Fine- lost battery allowable amount containers.
bad- a significant loss of capacity.
Terrible It's time to think about replacing the battery.
Almost died— The battery needs to be changed urgently!
How do I check the number of iPhone recharge cycles completed on a Mac or Windows computer?
Use the program. After installation, connect your iPhone, select it in the section devices, click on the inscription More Information and look at the number opposite the inscription CycleCount- this is the number of recharge cycles already completed.
Below you will also find another useful information about the battery of your iPhone - capacity according to the passport ( DesignCapacity), actual capacity after fully charged ( FullChargeCapacity), battery wear level ( BatteryCurrentCapacity).
Depending on how intensively you use your device, after 2-3 years you may need to replace the iPhone/iPad battery.
The need for replacement is indicated by symptoms such as a charge retention problem and external changes battery. Of course, an iOS device can quickly discharge for other reasons - due to the activity of various services or, for example, screen settings - but if a smartphone or tablet simply turns off at 20-40% charge, this is not normal.
Visual Signs that an iPhone Battery Needs to be Replaced
It is difficult to visually assess the condition of the battery, since the iPhone has a non-separable case. However, when the battery reaches its last days, gas accumulation in the battery can be diagnosed by changing the shape of the mobile device case or by a slightly convex screen, which, when pressed, can lead to divorce.Of course, problems with the screen can also arise for other reasons, however, you should not delay going to a service center, because a swollen battery can portend an expensive repair, not to mention a threat to the health of the device owner.
Despite its inaccuracy, it is worth taking into account the described signs, but information about its recharge cycles and current capacity will tell much more about the state of the battery.
How to find out the number of iPhone charge cycles
The battery has a limited number of recharge cycles, after which it is considered a spent resource and requires replacement. You can continue to use this iPhone/iPad battery, but the operating time of the device will be reduced.Unfortunately, you cannot get information about iPhone charge cycles in the settings, but you can use the iBackupBot program for Windows and Mac.
Download and install iBackupBot on your computer, connect with a cable mobile device to the PC and in the window with the basic information about the device, click on "More Information". 
Deciphering the main meanings:
- CycleCount - number of charge cycles;
- DesignCapacity - nominal battery capacity declared by the manufacturer;
- FullChargeCapacity - battery capacity;
- Status - battery status;
- BatteryCurrentCapacity - current battery level.
Well, if the result did not satisfy you and you decide to change the battery, before going to the service center, try
How to Determine iPhone and iPad Battery Wear Level
Replacing the iPhone and iPad battery is not as easy as it is with Android devices, so when buying a used smartphone or tablet, it will not be superfluous not only to visually evaluate the device, but also check the battery condition. You can do this with apps like Battery Life.
Battery life- free iOS app determines the degree of wear of the battery. In addition to assessing battery health, Battery Life also provides information about the charge level and current capacity of the battery (compared to the capacity of a new battery).
Download Battery Life for iPhone, iPad (Free)
If you did not find an answer to your question or something did not work out for you, and there is no suitable solution in the comment below, ask a question through our . It's fast, simple, convenient and doesn't require registration. You will find answers to your and other questions in the section.
Every next iPhone exacerbates the problem with the battery. My first iPhone 5S after 9 months of intensive use lasted no more than 4-5 hours.
How can I find out the level of wear of the battery in the iPhone? There are no built-in tools.
If you open the App Store, then there you will find many programs for checking iPhone battery wear, but can they be trusted.
You probably know that Apple devices, unlike android, have a closed system and do not allow penetration into the kernel.
If you search the web for apps to view the wear level of your iphone battery, you will be offered "Battery Life".
I entered such a request in the App Store and the service gave me several programs with the same name from different developers. Let's check them out.
The first program to check the battery wear on the iPhone
The first on the list was an application from the developer "Victor Robin". After installation, it gave me information that the condition is good, and the battery wear level (written at the top) is 76%
Pretty strange. 76% and good condition. Let's see what the third app from developer RBT Dighal has to say.
Second app to check battery wear level on iphone
To be honest, after installing the second program, I'm a little shocked - everything is bad here, and the wear rate is 24%.
I get the impression that the first Battery Life shows how much good capacity is left, and the second how much has already worn out.
This, as it were, is confirmed by the percentages of 76 and 24 - if you add them up, you get 100. This is also confirmed if you look at the time period of work - it coincides in both.
Let's take another look at the iphone battery wear rate in a program that I trust - AIDA 64.
The third program to check battery wear on iphone
You can also download AIDA 64 for free in the App Store. I already have it installed and this is what it shows.
AIDA 64 showed 23.61% wear (wear left line). I trust this application, so I think the result is correct.
Moreover, I see that my battery is about 25 percent discharged faster than it was after the purchase.
Battery life is undoubtedly important for most users and there are ways to improve it, but I won’t describe how to do it here, since such an entry already exists - you can find it in the IPHONE menu or through the search.
You can more accurately determine the level of wear if the iPhone is jailbroken, but it requires software hacking.
Only iPhones are expensive and I do not recommend this to you. There is also the application "Battery Percentage - Your Device Doctor", where you can check the battery status, processor temperature and see if the pixels have disappeared on the screen
Thanks to GUI You can find out what condition the most interesting elements of your phone are in.
It has a beautiful minimalist design and is available for free. Thanks to him, you can learn a lot about your device, only at the time of writing the Russian language is not available.
NOTE: the iphone battery wear drops to 80% after 500 recharge cycles, and the iPad can withstand twice as much - 1000. Good luck.
