Yes, you want to know breaking news as soon as it happens or keep up with Facebook® comments the instant they are posted to your wall, but these notifications require power. Turn them off when you need to conserve energy and disable location-based services when not in use. Change the display settings on your phone so that your screen time-out is at a lower setting. Make sure Bluetooth is turned off when not in use so your device isn’t trying to pair with an accessory that isn’t there.
Turn off your GPS options, too. Live wallpaper applications can also affect battery performance.
Regular software update Note that it also takes at least three days to see battery improvement after updating the software
Look for apps like iOptimizer or Battery Graph that help you monitor your battery use
