Named a dangerous feature of new smartphones

DxOMark laboratory experts have found out how the always-on display mode affects the autonomy of a smartphone. The results of the study are published on the company’s website.

The authors tested the work of the popular Always on Display function, in which the time and other data are constantly displayed on the phone’s lock screen. According to the results of the tests, the laboratory experts called this feature dangerous for the battery and display of the device.

During testing, experts tested the function on iPhone 14 Pro Max, Google Pixel 7 Pro, Xiaomi 12S Ultra and Samsung Galaxy S22 Ultra smartphones. On all devices, automatic screen brightness was set, Wi-Fi and Bluetooth were disabled, and flight mode was activated. During the test, it turned out that with the Always on Display option active, gadgets were discharged three to five times faster.

So, with the Always on Display function turned off and on, the iPhone 14 Pro Max worked 466 and 122 hours, respectively, 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 feature can lead to screen burn-in.

At the end of December, Xiaomi asked users of the brand’s smartphones not to use toothpaste to repair broken screens. The company explained that the microparticles present in the toothpaste cannot effectively repair the cracks on the screen.
