Tips to improve battery life include: Turning off Wi-Fi If you don't need to download big files, and you aren't performing some crucial task online, turning off WiFi will let the battery rest. Disable Location Services Apps that use location are constantly communicating with cell towers to pinpoint where you are. While they're doing it, your battery is dying. Turn them off in settings when you need to get that last bit of life. Dim The Screen Dim the brightness of your screens to give battery life a boost. Lowering the default brightness will ensure that the phone uses less charge over time. Turn Off Push Notifications The function that allows your phone to automatically download new email, and notifications from third-party apps, also makes your battery run out faster. If your phone's almost dead, go to settings to turn off this feature. Turn Off Vibrate It takes more energy for your phone to vibrate than it does to ring. Remove any unnecessary apps Apps running in the background of your phone will make it run out of juice faster. Shut down all the apps you don't need to keep it going a little longer. If followed, these tips should drastically improve the life of your smartphones battery.
