Turn the data off When you do not need to use data, it is better to switch it off. Data can be a big drain on smartphone batteries, and it makes no sense to keep it on when you hardly need it. Switch off the Bluetooth When Bluetooth is kept turned on, it continuously searches for new devices and signals. This constantly drains your battery and your mobile goes dead without pretty much doing anything. The same holds true for GPS and WiFi. Turn off the key sound The battery gets drained a little each time your phone makes a sound. Turn off the sound made by your phone when you press any of the keys. You can do this from the ‘Settings’ option in your phone. Reduce the screen brightness When you are indoors, a very bright mobile screen does not make any real sense. Reduce the brightness as soon as you walk into your home or office. Reduce your screen brightness and the battery will last longer. Stop the vibration mode Phones in vibration mode are a big drain for their batteries, and you should use the normal mode to make the charge last longer.
