Android 15 could help protect your data and extend battery life with adaptive timeout

Screen timeout isn't new...
Correct, but it being adaptive is. I have my screen timeout set for 5 minutes. If it's adaptive, when I set my phone down it will recognize that I'm no longer using it and turn off the screen before it gets to 5 minutes.
But that's not new. Adaptive screen when at my ear or when I put it face down had been a thing for years.
Don't set it down to watch a video then.
