How to Extend the Life of Your Galaxy Tab Battery
A surefire way to make a battery last a good long time is to never turn on the Galaxy Tab in the first place. That’s kind of impractical, so rather than let you use your Galaxy Tab as an expensive paperweight, here’s a smattering of suggestions you can follow to help prolong battery life in your Galaxy Tab:
Turn off vibration options: The Tab’s vibration is caused by a teensy motor. Though you don’t see much battery savings by disabling the vibration options, it’s better than no savings.
Lower the volume: Additionally, consider lowering the volume for the various noises the Galaxy Tab makes, especially notifications.
Dim the screen: If you look at About tablet on the Settings window, you see that the display (labeled Screen) sucks down quite a lot of battery power. Though a dim screen can be more difficult to see, especially outdoors, it definitely saves on battery life.
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 notification panel.
Turn off Wi-Fi: It’s a major trade-off, but while Wi-Fi networking keeps the Galaxy Tab on the Internet, it does drain the battery. Away from a single location, Wi-Fi “wanders” and isn’t useful for an Internet connection anyway. So why not turn it off?
