First stage: put devices with Always on Display turned off. Wi-Fi, GPS, Bluetooth, NFC, and Cellular are also turned off. The devices were in standby mode, and the decrease in charge was recorded from 80 to 20%.
Second phase: Smartphones were in the same state. The only difference is that the AOD feature has been enabled.
It turned out that devices are discharged 3-5 times faster with Always on Display enabled. The experts explained that in the first test, smartphones consumed 10 mA, in the second – from 35 to 50 mA.
Always on Display has another drawback – pixel burn-in. If the same information is displayed on OLED screens in one area, the image may remain there forever. It will look like a watermark. Manufacturers try to avoid this problem by slightly moving each icon on the display.
We advise you to disable Always on Display if you do not use it. This will save you precious battery life.
