Because why the hell not?
Doze is amazing – arguably the best feature of Android™ Marshmallow and Nougat. But with its caveats. It can take at least 2 hours to kick in (if the device is stationary, not charging etc). If you move around, even with the screen off, doze won’t kick in, so there are a lot of potential battery saving opportunities lost, gone with the wind.
With Naptime by toggling in the “Aggressive doze” options (and assuming you’re rooted) Doze will kick in right after you screen off AND it disables your sensors so that it doesn’t kick you out from doze mode if you move around. When your device screens on everything goes back to normal. It’s just like magic.
If you don’t want to use “Aggressive doze” you can also tune all the framework doze options to your liking. Although it’s a bit for advanced users each item is bundled with a description.
1 – Update Google support libs
