Why does my battery drain so quickly?

Understanding the phone's power usage is important to understand what is causing the power to drain.
  • The Battery Usage History will show which apps and system services are using battery and an estimated percentage of the battery power the app or service has used. See How do I check battery usage on my phone?.
  • Updating apps and software can help improve battery life by making sure the latest improvements to performance are installed. Update all apps in the Play Store app and check for updates to your phone's software under Settings > About > Software updates or Settings > Software updates.
  • If the issue started recently, uninstalling apps that have been installed since shortly before the start of the issue may help. Some apps are not optimized for battery use as well as others, and may affect the battery life of a device. Go to Settings > Apps or App Manager. Select an app that was installed shortly before the battery drain issues began. TapUninstall.

How do I check battery usage on my phone?

  1. Go to Settings, and then tap Power.

    Or Settings > Power > Battery Manager.

  2. Tap Battery usage to find the battery usage history.

    In phones that have Android 6 or later, you'll see the top overall contributors to battery drain. If a particular app shows high battery usage, try reducing the frequency the app is in use, limiting the sync frequency or restricting the background functions of the app to help extend the battery life of the phone.
