Boost Your Phone Battery Life APK

With this great application Boost Your Phone Battery Life you can see an organized breakdown of what's consuming your phone's battery. Applications and features will display in a descending list of battery hogs.

Turn unnecessary hardware radios off. It's great that today's phones have LTE, NFC, GPS, Wi-Fi, and Bluetooth, but do you really need all five activated 24 hours per day? Android keeps location-based apps resident in the background, and the constant drain on your battery will become noticeable, fast. If your phone has a power control widget, you can use it to quickly turn on/off GPS (the largest power drain), NFC, Wi-Fi, Bluetooth, and LTE. On stock Android, swipe down to bring up the Notification bar, and then tap the icon on the top right corner.

Turn down the brightness and turn off Automatic Brightness. It's probably obvious at this point, but you'll be surprised by how much this one alone helps to improve battery life.
Explore the battery saving features on your phone

All ROMs, whether stock Android, OEM UIs such as TouchWiz, or custom ROMs like CyanogenMod, have various settings in the menu to help conserve or optimize battery consumption.

HTC has Extreme Power Saving Mode, Samsung has Ultra Power Saving Mode, Sony has STAMINA mode and so on. Find these various options for your device and ROM and make them work for you.

Even if your phone doesn't have layers of battery saving features like some (or you simply don't want disable so many features), at least make use of the basic battery saver mode. Even stock Android Lollipop has it by default and Android M has the great Doze feature (as mentioned above) to help reduce battery consumption while your phone is asleep.
