Battery saver (Power saving mode)

While enabled, Battery saver setting reduces the battery consumption of your device by various means, such as

  • Reducing the processor speed and device performance
  • Disabling or limiting vibrations
  • Limiting some use of background data (mobile or Wi-Fi data) by apps not in use
  • Limiting the use of location services.

You may enable the Battery saver when you know you are going to be without access to a charger for an extended period of time, or if your battery level is getting low and you want to ensure it lasts as long as possible.

Some apps that rely on background data to sync may sync less frequently or not at all while Battery saver is enabled.

Note that the Battery saver's behavior may differ on some devices. Sometimes it will be called Power saving mode. In addition, some devices such as selected Samsung Galaxy devices have an additional "Maximum power saving mode" which takes additional action such as changing the theme to black, further reducing performance and on some devices, disabling certain apps.

Note that Battery saver is not active while your device is plugged into a charger or power source.

Turn on automatically

You can configure Battery saver to switch on automatically when your device's battery level reaches a certain low point, such as when the battery level hits 15% or 5%.
