Android system actually has a few built-in options for keeping tabs on running processes too. This information is accessible via the Developer Options menu in Settings. If Developer Options is not visible then
- If you don’t already have this menu enabled, just go to Settings > About Phone
- Then tap the Build Number repeatedly until the notification pops up.
- Developer Options will now appear at the bottom of the Settings menu.
Running Services will tell you what percentage of the time an app is running as well as its average and maximum RAM usage. You can also tap on service to force stop it or report a misbehaving app. You can learn which apps are always running on your system for good reason (like Google Play Services) and those that shouldn’t be (games you’re not playing or music players you’re not using).
Likewise, check your Battery section in the Settings. Under App usage you a breakdown of the biggest battery suckers, what processes they’re running, how much battery they’re eating, wake lock stats, mobile and Wi-Fi data sent and received and more.
