Stick to these simple tips and your phone will stay powered up much longer:
Lower your screen brightness
This is probably one of the most obvious and quickest changes that you can make in terms of saving the battery on your phone. It takes a lot of power to give you a super bright display and the chances are you won’t need it most of the time.
Switch to Wi-Fi when you can
Using 3G (or even worse, LTE in the newer phones) is a massive suck on battery life. If it’s possible, turn off 3G (or LTE) and switch to Wi-Fi. You won’t be able to do this all the time, but it is a useful trick if, for example, you are traveling or in a place where you can’t take calls but do have Wi-Fi.
Turn off Wi-Fi (when you’re not using it)
When your phone’s Wi-Fi is activated, the device is constantly looking for new networks and, as a result, sucks life from your battery. Turn off Wi-Fi and only switch it on when you are going to use it or look for a network.
Only use location apps when necessary
