How To Boost Your Android Battery Life: Rooted And Non Rooted Android Smartphone

How To Boost Your Android Battery

One of the ugly things that android users normally faced is limited battery life. Unless your smartphone comes with a sufficient battery capacity there is no way you can avoid it. What is the essence of having a high-end or a mid-end Android phone that its battery can't last for 6 hours? Here is how you can maximize your limited battery life for both rooted and non rooted Android device.

For Rooted Android Phone:

If your Android smartphone is rooted, you can maximize your battery life by applying one of these procedures:

1. Changing your phone kernel

This can really help in the sense that it gives you access to regulate the voltage and the CPU speed of your device (This can cause adverse effect on your phone if you don't know what you are doing). There are several CPU governors you can choose from to regulate how your CPU process and handle data in and out. Stock kernels cannot be fully twisted like custom kernel. Also, developers most of the time undervolt their kernels to help in maximizing the phone battery. To underclock or overclock your phone CPU you can use SetCPU.

2. Firewall

Using a firewall app to block some certain apps and denying them the permission to automatically connect to the internet can also help boost your battery life, because excess internet connectivity can drain your battery faster than you think. There are some firewall apps that can work on non rooted android phones, but they are not as fully effective as those that were meant for rooted ones. If you are looking for a firewall app for your rooted phone we recommend you use DroidWall, Download DroidWall.

For Non Rooted Device

If you have not root your phone or gain superuser access, these are ways you can enhance your battery life.

1. Lowering Screen Brightness

The default screen brightness option in all Android phone is Auto Brightness, but sometime you get more than you need. Un-selecting this option and lowering your phone screen brightness to the minimum can save you some battery juice.

2. By Using a Task Manager

There are many app process that runs in your phone background and not all of them are needed to keep your phone in a good state. Some simply consume your phone RAM and use your CPU without doing any specific task, these intensive apps can even slow your phone down and consume your battery. Using a task manager is the best way to detect and stop them. Task manager is a must for every android phone. There are several task managing apps on Android market, we have ES File Explorer, Android Task Manager and many more, you can download any.

3. Firewall

There are "No Root" firewall apps that work fairly on non rooted Android phones, though they simply deny the app from auto connecting to the internet. There is currently one that seems to work effectively for non rooted phone but it doesn't work on LTE, it is called NoRoot Firewall. You can download it from here.


There are still many ways you can save your battery - disabling some sensors like Auto Rotate and turning off unused connectivity like Bluetooth, GPS and Wifi can also help.
