Having the best battery life is something all smartphone users dream of but no matter how careful we are sometimes, it just seems like a pipe dream. Google seems like they want to help out, though. A new feature spotted in the Android 8.1 Developer Preview pinpoints which apps have been draining your battery life without your knowledge. Seen in the battery section of the settings, it shows the app with a red battery icon and specifies how it’s draining the battery. When you tap on the warning, you will get options on how to fix it—such as killing the app or just turning off location data for it. Unfortunately, we aren’t 100 percent guaranteed that Google will bring this over to the final release of the operating system. But this is definitely one feature we wish they’d keep in.
