TLDR
There are a few things that the user can do to increase his or her battery life in an Android phone. These methods are mostly related to software factors which means that there are no general power saving moves to perform on all types of smartphones. Turn off your GPS altogether from the main settings of the phone. Turn on the dark screen on an AMOLED or OLED display to preserve your battery life. Don't use Automatic WiFi to keep looking for networks to connect to in order to be ready to connect.via the TL;DR App
