Battery health is a key metric that you can easily review on your Apple iPhone or iPad. The health of your battery will help you determine if you need to make some performance or usability changes on your device to extend the daily charge of your device.
Battery health is different from the simple battery life readout that appears on your home screen. The health settings provide multiple data readouts and user stats. The data is both in-depth and easy to understand by even those who are less technically inclined.
Our guide will provide the simple steps for finding this data, in addition to a robust guide with images to help you easily walk through the process of viewing charge data. You won’t believe how easy it is to get detailed reporting quickly.
Note – these steps were tested and confirmed on iOS 15.
