Pay attention to the amount of time each app consumes. The longer the wakelocks associated with each app, the greater the battery drain. If the wastrel service isn’t something regularly used, it’s likely a background service that’s either improperly configured or poorly designed.
If you tap on an app from the main menu you’ll be presented with several options: First, you can uninstall the app via the Play Store or, second, you can open the app to reconfigure it. For misbehaving Google or system apps I suggest opening the app. Specifically, turn off the app’s access to GPS and/or try logging out.
