Rapid battery drain is a relatively common issue not only with the Samsung Galaxy Tab, but with mobile devices in general. The good news is that rapid battery drains are typically fairly easy to troubleshoot and fix yourself. More often than not, the culprit is a malfunctioning app or a power setting.
Bear in mind that fast battery drain is to be expected during processor-intensive activities. If you’re updating your OS or playing a game for long periods of time, keep a charger close at hand. But if your battery starts inexplicably draining while you’re not doing one of these things, then it’s time to start troubleshooting the problem.
Let’s Start With Your Display Settings
Keeping your screen brightness at 100 percent all the time can have a measurable negative impact on your battery life. Trying using the tablet’s “Auto” screen brightness setting which saves battery by automatically adjusting the brightness level based on the ambient light around the device. Keep the “Screen Timeout” setting low as well so that the display doesn’t remain on and use your battery when you don’t need it to.
Next, Check Your Apps
More often than not, the source of the problem can be found by going to the “Battery Usage” panel of your battery settings menu. This will show you all the apps that are using your battery, and how much. You may notice a rogue app using a disproportionate amount of your battery. In some cases, it may be an app that appears to be closed, but continues to use your battery anyway. Select that app, tap Force Stop, and you should notice that your battery usage returns to normal. You may have to update the app or uninstall it to prevent the problem form reoccurring in the future.
Perform a Soft Reset
If all else fails, it never hurts to reboot your device. To perform a soft reset, hold the Power and Volume Up buttons at the same time until the device turns off. Once Your Galaxy Tab resets, use it as you normally would and check to see if the unusual battery drain persists.
