Here’s how iPhone 14 Pro’s always-on display drains battery with and without wallpaper enabled

The iPhone 14 Pro and iPhone 14 Pro Max’s always-on display has raised questions about battery life when enabled. Being very confident about the screen refresh rate, which can be reduced to 1 Hz and thus consumes less energy, Apple has made sure that it will not quickly lose the autonomy of the iPhone. We now have a video test that shows how the always-on screen drains the battery with and without the wallpaper enabled, as well as when the feature is turned off completely.

iPhone 14 Pro autonomy test always on/off screen

3 iPhone 14 Pro used for testing were reset to iOS 16.2. Note that with this version, Apple has added new settings that allow you to hide the wallpaper or notifications when the “Always On” display option is enabled on the iPhone 14 Pro and iPhone 14 Pro Max. All 3 phones have no apps installed (so they don’t support widgets) and are logged out of iCloud with airplane mode enabled.

In the first part of the test Lasting 8 hours (at 150 lux ambient brightness), with the screen on with the wallpaper on, the iPhone 14 Pro lost 2% and rose to 98%. The model with the screen on without wallpaper also lost 2% battery. As for the iPhone 14 Pro Max, whose feature was completely disabled, it did not lose a single “crumb” of its charge.

In the second part of the test which also lasted 8 hours (this time with an ambient brightness of 1000 lux), the iPhone 14 Pro with the screen on with the wallpaper lost 3% and rose to 97%. The model with the screen on without wallpaper lost 2% battery. As for the iPhone 14 Pro Max with the feature completely disabled, it still holds 100% charge.

Finally, when the third and final part of the test Lasting 24 hours (again with 1000 lux ambient light), the iPhone 14 Pro with screen and wallpaper lost 20% of its battery and therefore dropped to 80%. The model with the screen on without wallpaper lost 16% battery (84% remained at the end of the test). In turn, the iPhone 14 Pro Max, with the function completely disabled, wins again, keeping all its load.

So, with the screen still on and the wallpaper visible, the battery loses 0.8% charge per hour; when the screen is always on without wallpaper, it loses 0.6% power per hour. In addition, it should be said that the screen, which is often always on, can turn off automatically in real life. Because Apple reported that the iPhone 14 Pro and iPhone 14 Pro Max screen (always on) turns off in the following situations:

  • Your iPhone is face down on the table
  • Your iPhone is in your pocket or bag
  • The relaxation mode is activated in the concentration unit
  • Power saving mode is activated
  • Your iPhone is connected to CarPlay
  • You’re using Continuité (which lets you use your iPhone as a webcam on your Mac)
  • You haven’t used iPhone for a while (iPhone learns your activity patterns and turns the screen off and on, including when you set an alarm clock or sleep schedule)
  • iPhone detects that you’ve moved away from it with a paired Apple Watch (screen will light up when Apple Watch is close to iPhone again)

Another interesting comparison during the video is Apple’s iPhone 14 Pro and Samsung’s Galaxy S22 Ultra: they both completed the 24-hour test with 84% charge.
