Caffeine is a quick settings tile that helps you change the screen wake up time.
Similar to CM13, you can toggle the wake up time between 5mins, 10mins, 30mins or infinite by tapping the tile multiple times. Note that there is no app launcher icon, to open the app, long press the Caffeine tile.

From version Caffeine 1.0.1:
