Caffeinate works by creating a Tile in your Quick Settings, a feature only available in Android Nougat (7.0) and higher.
Upon toggling, Caffeinate will keep your screen awake for five minutes (you can increase this timer by tapping the tile, or change the default time in the settings). After times up, your screen will continue sleeping normally.
Pretty much works exactly like CM's (and now LineageOS') caffeine function.
A few things to note...
- Caffeinate posts a notification when activated (and removed when the timer hits zero) in order to prevent the service from being killed. You can disable notifications for Caffeinate by long pressing the notification, and choosing to block all notifications (You'll miss the quick cancel option however!).
- By default, Caffeinate has an app launcher icon just like any other normal app on your phone, but you can choose to hide this icon through Caffeinate's settings menu.
- Caffeinate uses Firebase, in order to report crashes, some analytics, and remote config (A/B testing).
