 ## Battery optimized devices
 Some devices kill NewPipe when playing in background. If you feel like your phone is doing such evil things, head over to https://dontkillmyapp.com/ to learn more on whether your device is really affected. We've already created [a support page](https://newpipe.schabi.org/FAQ/tutorials/bugs-huawei-background-player-workaround/) for that and would like to enhance the app to notify users of these devices and provide more info in our FAQ.
