One of the biggest complaints about iOS devices (mainly iPhone) is battery usage, often this can be due to ‘run away apps’ (apps that are using large amounts of battery in the background) some of which may rarely be used. But how can it be determined which apps may be affecting battery life? There is a solution built directly into iOS 11.
Select the ‘Settings’ option on the iOS device (img.1).
Once in ‘Settings’ scroll down and select ‘Battery’ (img.2).
Then scroll down a little and you will be able to view your battery usage for each app over the last 24 hours or last 7 days (img.3).
From this it can be determined if an unused app is hogging battery and therefore it can be deleted of if it is an app that is utilised maybe an alternative can be found on the App Store.
This is an easy way of checking what is happening to an iOS battery.
