Lenovo – alarms and notifications

Explanation

We’re still gathering more information on battery saving features on Lenovo phones.

Lenovo P2 has a very good battery life, but at a cost.

For an app to work in the background:

enable the padlock icon at an app in the right top corner in the overview of running apps. It’s only then actually running as a foreground process. If you swipe it away, its background process will be killed mercilessly.

It does not matter if the battery/power optimization is on or off in Settings -> Apps -> Circadian -> Battery.
