If you’re struggling with performance issues on your Android device, or trying to track down suspicious battery drain, then you might want to take a peek at which apps are running in the background. This guide will show you exactly how to do it and offer up some suggestions on what you can do about it.
Before we get into the details, it’s important to note that the majority of Android apps will be running in the background because they’re doing something they’re supposed to do. Android is good at switching things in and out automatically to maintain smooth performance, so you need to think carefully before interfering.
Check your battery usage
Your first port of call should be the battery usage breakdown that’s built into Android.
Go to Settings > Battery > Battery usage.
If you scroll down, you’ll see there’s a percentage listed next to each entry showing recent battery usage. You should expect to find Screen as the top listing and there will likely be some Google apps listed. What you’re looking for is an app or game that seems to have taken up a suspiciously large amount of battery. If you’ve used something briefly or not at all and yet it still chewed through a chunk of your battery life, then it’s a possible candidate for action.
