Why does my battery drain so quickly?

Understanding the phone power usage is important to understand what is causing the power to drain.
  • Check the battery usage information to see which apps and system services are using power. This information shows the estimated percentage of the battery power the app or service has used.
  • Updating apps and system software can help improve battery life by making sure the latest performance updates are installed. Update all installed apps in Google Play Store and check for the latest updates on your phone.
  • 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 as well optimized as others, and may affect the battery life.

    Depending on your phone model, do one of the following:

    • Go to Settings > Apps & notifications. Tap See all to display the app list.
    • Go to Settings > Apps.

    Tap the app that was installed shortly before the battery drain issues began, and then tap Uninstall.
