With the introduction of an always-on display in the iPhone 14 Pro and iPhone 14 Pro Max, many users have wondered how the feature will affect their battery life. A new video shows how much battery drain there is with the always-on display and if turning off the wallpaper reduces that drain.

The always-on display is black other than for the clock, date, any widgets you have set up on your lock screen, and recent notifications, if you enable them. PhoneBuff tested whether or not disabling the wallpaper affects the battery life.

In the test, it was found that if the wallpaper is enabled for the always-on display, the drain on the phone will be less than if it is disabled.

PhoneBuff compared the always-on display technology of the iPhone 14 Pro to that of the S22 Ultra. It was found in the comparison that the clock on the always on display would be moved around to prevent the display from burning out.

No such thing happens on the iPhone as time and all other information stays in place. After 24 hours of the always-on display, the two phones drained at the same rate.
