Battery backup is not good save your battery!!!

If your battery is dying too quickly, it might be because of background apps that you forget are running. Beefing up your battery life can be easier than you think.

Navigate to Settings>>Apps>>then swipe to the "running" tab. You'll see the apps that are using the most processing and battery power. If you don't use a high-power app very often, simply tap the app and then tap the "quit" button. Getting rid of energy-sucking apps should give you a small boost to your battery life.
