How to Extend Your Samsung Galaxy Tablet’s Battery Life

By Dan Gookin

A surefire way to make a Samsung Galaxy tablet battery last a good long time is to never turn on the device in the first place. But rather than let you use your Samsung Galaxy tablet as an expensive paperweight, let’s offer a smattering of suggestions you can follow to help prolong its battery life:

  • Turn off vibration options: The tablet’s vibration is caused by a teensy motor. Although you don’t see much battery savings by disabling the vibration options, a minuscule savings is better than no savings.

  • Lower the volume: Consider lowering the volume for the various noises the tablet makes, especially notifications.

  • Dim the screen: The display (labeled Screen) sucks down quite a lot of battery power. Although a dim screen can be more difficult to see, especially outdoors, it definitely saves on battery life.

  • Adjust the screen timeout: Make the screen sleep at a shorter interval to save valuable battery life. Or manually lock the tablet, especially if you’re just listening to music.

  • Turn off Bluetooth: When you’re not using Bluetooth, turn it off. You can turn it off easily from the Quick Actions at the top of the notifications shade.

You’ll find a Power Saving Mode item in the Settings app. (You might need to touch the General tab first). Select the item on the left side of the screen. Then touch the button atop the screen to activate Power Saving Mode, and select items shown on the screen to help manage how the tablet uses battery juice.
