Soon, Android will finally let you monitor which apps use the most battery life on your phone. If you’re confused and thought you already had this functionality, you might be right! Some Android skins, like the one on the Galaxy S8, and some apps, like Greenify, already make it possible to detect which applications are draining your phone’s battery. However, in the next release of Android Oreo, that feature will at long come standard on Google’s mobile OS.
