Most of modern Android devices come with an app or mechanism, which automagically tries to figure out how to save battery and as a result might kill certain 3rd party apps. This might result in removing scheduled tasks and jobs, (e.g. alarms not going off, push notification not working, etc.). In many cases this happens completely independent from battery saving mechanisms of Android, in my case i couldn't make more battery optimization when i detect some devices model, i redirect user to the start up manager to whitelist my application
