With the introduction of an always-on display in the iPhone 14 Pro and iPhone 14 Pro Max, many users have wondered how much impact the feature has on battery life. A new video takes a careful look at just how much battery drain there is with the always-on display and whether turning off the wallpaper reduces that drain.
it was found that by having the wallpaper enabled for the always-on display, an iPhone 14 Pro will drain around 0.8% per hour, compared to 0.6% an hour for the wallpaper disabled on the always-on display.
