How much battery does each app use on your iPhone or iPad? You could say that of course the ones you use the most. But thanks to the battery usage function, you can find out quite accurately. It will also tell you how much time you spend on individual titles. Thanks to this, you can limit their use and thus also increase the battery life of your iPhone or iPad. 

How to Find Out What's Using Your iPhone's Battery

If you want to see an overview of the battery charge level and your activity with your phone or tablet during the last day, as well as 10 days back, go to Settings -> Battery. Here you will see a clearly defined summary overview. But this is not the only information you will read here.

All you have to do is click on one column delimiting a certain period, which will then show you the statistics during that period (it can be a certain day or a range of hours). Here you can clearly see which applications contributed to the battery usage during this period, and what the battery usage ratio is for the given application. If you want to see how long each app has been in use on the screen or in the background, tap View activity. 

The following usage options may be listed for each application: 

  • Background activity means that the app was doing something in the background and using battery. 
  • Sound means that the application running in the background is playing sound. 
  • No signal coverage or Weak signal means the device is searching for a signal or is being used with a weak signal. 
  • Backup and Restore means that the device has backed up to iCloud or restored from an iCloud backup. 
  • Connected to charger means the app was only used while the device was charging. 

You will also find out when your device was last connected to a charger and what the last charge level was. Clicking anywhere outside of the columns will give you an overview again. 

Want to extend battery life? Change the settings 

When viewing your consumption information, you may see suggestions such as Turn on automatic brightness or Adjust screen brightness. This happens when the software evaluates that changing these settings could increase battery life. If you want to extend the battery life on your iPhone, it is of course also offered turning on Low Power Mode.
