Specialists of the DxOMark laboratory have discovered how the always-on display mode affects the autonomy of the smartphone. The results of the research are published on the company’s website.

The authors tested the operation of the popular Always on Display function when time and other data are constantly displayed on the phone’s locked screen. According to the results of the tests, laboratory experts described this feature as dangerous for the battery and screen of the device.

During testing, experts checked the functionality of the function on smartphones iPhone 14 Pro Max, Google Pixel 7 Pro, Xiaomi 12S Ultra and Samsung Galaxy S22 Ultra. Automatic screen brightness is set on all devices, Wi-Fi and Bluetooth are disabled, flight mode is enabled. During testing, it turned out that gadgets discharge three to five times faster with the Always on Display option active.

In other words, when the Always on Display feature is turned off and on, iPhone 14 Pro Max is 466 and 122 hours, Google Pixel 7 Pro – 367 and 139 hours, Xiaomi 12S Ultra – 495 and 103 hours, Samsung Galaxy S22 Ultra – 417 and 136 hours. Experts noted that in addition to increased battery discharge, the always-on display function can cause screen burn-in.
