How to Read your Android Battery Graph The battery graph in your Android phone lets you visually see the battery consumption of your mobile phone over time. Learn how to read and interpret the battery history graph. Your Android mobile phone includes a built-in app to help you visually monitor the battery usage pattern. Go to Settings > Battery (the app’s location may vary for your version of Android) and you’ll see a history graph detailing which apps have been consuming the most battery power and how long you can use the device before the battery is completely drained off. If you observe the Android battery graph more closely, you’ll find some other interesting details as well. For instance, you’ll know the pattern of your mobile signal strength, how often apps running in the background ‘wake up’ your sleeping device and so on.

This is the main battery graph and is easy to interpret. If there are any breaks, it indicates that the device was powered off during that period. If there are any red or yellow lines over the graph, it indicates that the charge was critically low during that period. The gray area represents the approximate remaining charge. Related Tip: Do not let your phone’s battery charge dip the below the 10% mark as that will affect your phone’s battery life in the long run. If you tap the battery history graph, it will provide a more detailed breakdown of the battery usage and charge times as shown in the screenshot below.
