How to Save Battery Power on an Android.

1
Turn on the power saving mode. For most devices, all you have to do is swipe downward from the top of the screen to bring up a menu. Scroll to the side until you find the power saving option, and select it.
The power saving mode may slow your phone down a little.
If you’re getting an instant notifications from social media applications, they will stop until you open the application.2
Turn off WiFi, Bluetooth, and GPS if you are not using them. All of these use battery power, even when you are not using them. For example, the wireless networking transmitter will continue to search for a wireless connection on a regular basis as long as it is turned on. This uses battery power, even if you are not browsing the internet.
To turn these features off, simply swipe downward from the top of your screen. Scroll sideways along the menu, and deselect the items.3
Turn off any apps that you are not using. Closing the app by pressing the back or home buttons is not enough; the app may continue to run in the background and drain battery power. You should access your device’s recent and background apps and shut them down manually. This will usually ensure they are not running in the background and using battery power.4
Put your phone on standby mode when you are not using it. Simply press the power button and the display will darken. This will reduce battery power. To leave standby mode, simply press the power button again; you may have to unlock your phone once it “wakes up.”

Turn off the phone vibration function. Press the volume buttons up and down until you leave the vibrate mode. It might be a good idea to turn off vibrations for text messages too. You will need to go to your Settings, and then to “Sound & Display.” If you can’t find the settings for messages there, go to “Applications,” and then “Messages.”Visit Our Site….
