Battery

 

Battery Percentage

When your turn on the Battery Percentage switch, you will be able to see the percentage of battery you have left in the top right corner of your iPhone in the status bar. When this is off you will just see the battery icon with a vague depiction of how much battery you have left.

Low Power Mode

Low Power Mode reduces the amount of power that your iPhone or iPad uses when the battery gets low.

To turn Low Power Mode on or off, go to Settings > Battery. You can also turn Low Power Mode on and off from Control Center. Go to Settings > Control Center > Customize Controls, then select Low Power Mode to add it to Control Center.
 

When Low Power Mode is on, your iPhone or iPad will last longer before you need to charge it, but some features might take longer to update or complete. Also, some tasks might not work until you turn off Low Power Mode, or until you charge your iPhone or iPad to 80% or higher.

Low Power Mode reduces or affects these features:

  • 5G (except for video streaming) on iPhone 12 models
  • Auto-Lock (defaults to 30 seconds)
  • Display brightness
  • Display refresh rate (limited up to 60 Hz) on iPhone and iPad models with ProMotion display
  • Some visual effects
  • iCloud Photos (temporarily paused)
  • Automatic downloads
  • Email fetch
  • Background app refresh

When Low Power Mode is on, the battery in the status bar will be yellow. You’ll see a yellow battery icon and the battery percentage. After you charge your iPhone or iPad to 80% or higher, Low Power Mode automatically turns off.

  • On iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max, Low Power Mode disables 5G (except in some cases like video streaming and large downloads) and also disables 5G Standalone (where available).
  • These devices have ProMotion display: iPhone 13 Pro, iPhone 13 Pro Max, iPad Pro 10.5-inch, all iPad Pro 11-inch models, and iPad Pro 12.9-inch (2nd generation) and later.
