Why Does Your Phone Lose Battery, Even When Not In Use?

Even when your phone is idle, the battery keeps draining for a few key reasons. First, background apps and services are still running, using CPU power and data. Also, the screen stays on for notifications and uses power. In addition, poor signal strength makes the radio work harder to connect. Finally, batteries degrade over time, so older batteries see a faster drain.

To maximize battery life, try disabling unnecessary apps, reducing screen timeout and brightness, switching to airplane mode when possible, and replacing batteries older than two years. Watch this video to get more tips on getting the most from your battery.
