Look for data on the device itself or use a computer for this.
The iPhone and iPad have lithium batteries that are subject to chemical aging. Over time, this leads to a decrease in the maximum capacity and peak performance of the battery. In other words, the battery holds the charge not so long and can slow down, or even disconnects at high loads.
The residual container depends on how many times IPhone has been charged. In fact, the number of charge cycles is the main indicator of the battery state. Original iPhone batteries retain up to 80% of the initial capacity after 500 cycles, iPad – after 1,000.
It is important to remember that with a battery wear and reduce its capacity to less than 80%, iOS activates the function of reducing peak performance in order to avoid sudden disconnection under load. As a result, the device will work more slowly, the brightness of the display and the volume of the speaker will decrease, as well as the frequency of the screen update. But the decrease in the processor frequency only works in the iPhone and does not apply to the iPad.
Exceeding the previously indicated number of cycles does not require an urgent battery replacement. If you are satisfied with current autonomy and performance, you can safely use the device further.
How to find out the general condition of the iPhone battery in the settings
Starting with iOS 11.3 The settings display basic information about the battery health. To view it, go to “Settings” → “Battery” and open the “battery state” item.
Keep in mind that this item is only on the iPhone – it is not in the iPad settings.
Unfortunately, the number of cycles is not indicated here – only the maximum capacity is available. If you are just interested in how worried the battery is, this will be enough. However, there are cases when you also need to find out the number of charge cycles – category. For example, when buying a used device. Then you should use one of the following methods.
How to check the condition of the iPhone or iPad battery on a computer with MacOS
The best way to find out the number of iPhone battery cycles in the presence of Mac is to use the free Coconutbattery utility. She will also show the capacity, age of the battery, manufacturer and many other information.
Download the application by link and open it. Connect the iPhone or iPad using a cable and click on the device “Trust this computer”.
Switch to the iOS device tab. Pay attention to the line Cycle Count – this is the number of charge cycles. Also see the Full Charge Capacy and Design Capacy parameters – this is the current maximum capacity and capacity of the new battery, respectively. By pressing the Battty Info button, you can find out the manufacturer, age and serial number of batteries.
How to check the condition of the iPhone or iPad battery on a computer with Windows
If you use a laptop or a PC with Windows, one of the most convenient options is a manager for working with iMazing iOS devices. It is paid, but has a trial period, which will be more than enough to check. The application is designed for backup and synchronization of iPhone and iPad, but also shows a lot of various information, including the state of the battery.
Download Imazing by link and install. Connect the iOS device using a cable and allow the connection by clicking on the gadget to “trust this computer”.
Select in the IPhone or iPad side panel, and then click the I icon “I” next to the image of the device.
Find the Battle Charge Cycles line in the list of parameters – this is the number of charge cycles. The factory (Battle Design Max Charge) and the current (Battle Effective Max Charge) are a little higher.
How to check the condition of the iPhone or iPad battery on the device itself
If there is no computer at hand, then if desired, you can find out the number of charge cycles directly on the gadget without using any applications. The necessary information is in diagnostic logs, the main thing is to know how to look for it.
Go to “Settings” → “Privacy” → “Analytics and Improvements” and open the “Analytics Data” item.
Find a file with the name Log -AgGREGATED in the long list and the latest date. Open it.
We are interested in the line COM.Apple.ioreport.BATTERYCYCLECUNT – immediately after it the number of cycles is indicated. The recording is closer to the end, but finding it is not so simple. In order not to do this manually, you can copy the text, insert into the “notes” and find it already with the help of the search function.
