With recent news about Apple throttling the speed on older iPhones with batteries that are degraded and the subsequent announcement that they have put in place a program to replace any battery in an iPhone 6 or later that requires it for £25.00 instead of £79.00 (see Apple’s Message) it is probably the appropriate time to check your iPhone’s battery health.
There are not, in my view, any reliable apps installable on iOS that will show the health of the battery due to the fact Apple does not make this information available to owners or third party apps. However, there is a great program that works on Mac and PC that can give this information, it is iMazing, which I have been using for several years.
The program iMazing (https://imazing.com) is £34.99 for a single machine license but offers so much more than just checking an iPhone’s battery. Other features include copying media between your iOS devices and your Mac or PC, app management (not possible in the latest version of iTunes), backup your iOS device and selectively restore information for specific apps, save and browse also print your iPhone messages, access the file system on your iOS device and much more.
The primary focus of this post is check the battery health of the iPhone and if you choose to use iMazing the process extremely quick and easy.
Once iMazing is purchased and installed, launch it and plug your iPhone into your Mac or PC via the Lightning to USB cable, the window displayed is relevant to your individual OS device. Now click on the battery icon in the lower right of this window (img.1).
The battery information is then shown in a pop up window which can be scrolled to show further battery statistics (img.2).
Battery health is clearly shown and further down the number of charge cycles is displayed, which is a good indication whether your battery is becoming degraded, the average life of an iPhone battery is 400 - 500 charge cycles.
This will give a good indication if you need to take your iPhone in and request a battery replacement under the £25.00 program.
