Android expert Mishaal Rahman over at Android Authority spotted some strings hinting at a new adaptive timeout feature in the second Android 15 Developer Preview. These strings explain that the setting “automatically turns off your screen early if you are not using your device” once it is turned on.
At this point, it is not entirely clear how Android will determine when a phone isn’t in use, but it likely goes beyond just the absence of touch input. It’s probable that it uses a similar sensing method as the current Screen attention setting, which uses your device’s front-facing camera to see if someone is looking at the screen.
With the new adaptive timeout feature in Android 15, you will be able to enjoy longer screen timeouts without worrying too much about security. The OS will cleverly turn off your screen and lock it when you are done using your device. Plus, this helps save battery since the screen won’t be on for too long, draining power unnecessarily.
