Check battery usage
To see an overview of your battery level and activity for the last 24 hours and up to the last 10 days, go to Settings > Battery.
When you tap one of the columns on your screen, you can see which apps have contributed to your battery usage during that time period and the proportion of battery used for the app.
To see how long each app has been in use onscreen or in the background, tap Show Activity. Under each app, you may see these usage types:
- Background Activity means that your battery was being used while the app was doing something in the background.
- Audio means that apps may play audio while running in the background.
- No Cell Coverage and Low Signal means that your device is searching for a signal or being used with a low signal.
- Backup & Restore indicates that your device has been backing up to iCloud or restoring from an iCloud backup.
- Connected to Charger means that the app was only used while your device was charging.
You can also see when your device was last connected to a charger and the last charge level.
Adjust settings to improve battery life
While viewing your battery usage, you may receive a suggestion such as Enable Auto-Brightness or Adjust Display Brightness. This is because the software has determined that changing these settings could improve your battery life.

Use Low Power Mode
If you want to extend the battery life on your iPhone, turn on Low Power Mode. This will reduce power consumption until you turn it off or charge your iPhone to 80%. When Low Power Mode is turned on, certain settings and features such as app updates, downloads of new TV shows or podcast episodes, email fetch and some visual effects, such as True Tone, will be reduced or disabled.

With iOS 11.3 and later, you can see your battery health and if a battery needs to be replaced. Find out more in iPhone Battery and Performance.
