Your iPhone stores some information about battery usage by the various apps on your device, which can be useful if you find that your battery is draining quickly. You can see what proportion of your battery has been used by each app, how long that app was active and being used on screen, as well as how long it was running in the background. Simply follow our tutorial below to see where this information can be found.
