Overclock your android device [Complete Guide]

Android phones enable users to make them comparatively faster than they already are, making users satisfied and happy as compared to the previous performance. This whole mechanism is known as overclocking, which basically means compelling the CPU to run faster than its current performance. The process is effective and increases power by 30 percent. Below are the few steps to overclock android to make your device supercharged immediately.

Before you start: read this

Before we go into detail about overclocking, it is essential to go through basic warning. Overclocking comes along with some disadvantages along with its benefits. Accelerating the clock of CPU causes extra heating and drainage of power. This generation of extra heat affects the life of your battery negatively.

The fundamental part is to avail your time. Don’t rush into things by directly aiming at increasing 30 percent speed. Evaluate and analyze speed after every increase. Then your device is functioning in its usual way then its battery and heat levels are quite decent. If things seem a bit off track then quit speeding and return to the previous stable clock speed.

Getting the right kernel for overclocking

Now let’s move on to the actual overclocking. The one thing that needs to be plucked the CPU settings of Android is basically a kernel which supports overclocking. Overclocking is predominant of modding community so, there is deficit of kernels, good ones, to pick from. All you need to do is avail the correct kernel according to the model of your phone.


To start with, look up for the model number of your device by going into Settings > About Phone. Additionally, mark the version of functioning android. Then, root your phone to overclock the CPU. There is no warranty for this mechanism, do it at your own risk and install a custom recovery which is a necessity.


You should give more of your time on searching the suitable kernel however, replacing it and overclocking is a piece of cake and takes minimum time. Websites such as, XDA Developers, are the most amazing start-up sites. You require following four characteristics in the right kernel:

  1. It is compatible with overclocking.
  2. It is supported by your phone.
  3. It works on your present version of android, and lastly
  4. It has a good standing and reputation.

Availing help from community will get easier if the kernel is famous (to track down some suggested settings).

Software for your kernel

Devoted softwares come along with a few kernels. These help user acquire up to the max from the kernel. This may include an overclocking slider, CPU governor settings, undervolting options and a lot more. In case, the chosen kernel has a companion app then utilize it and if it doesn’t look up for a generic overclocking or CPU manager app from Play Store.


You’re all set and ready to go if you have got the right kernel running on your phone’s android. For the following tutorial we’re using rooted Nexus 6 and overclocking it, running stock Android 6.0 Marshmallow using the ElementalX kernel.


Do check on your custom ROM, if you have it, to see if you require a kernel change.

How to overclock your Android

You need to root your device so that you can flash a custom kernel. Plus, you’re going to require a custom recovery installed.


  1. Be assured that your data is backed up. Perform this using your custom recovery, different apps or PC-based solutions.
  2. Following the selection of kernel it is advised that you download it without further ado. If you wish, you can even download it on your PC and copy the zip file to the root directory of your phone. However, it is simple to do it on your phone via recovery.
  3. Then, switch off your device and go to fastboot. This can be easily done by pressing Power and Volume Down. However, some makers might have a different set of key combination.
  4. While staying on the fastboot screen, make use of volume buttons to focus Recovery mode and later, click power button to choose it.
  5. We’ll now use TWRP after entering into your custom recovery.
  6. Select the ‘install’ button and handle to the area where you stored the initial kernel zip file.
  7. Flash the kernel zip file and hold for an advance alert. Few kernels (Elemental X) will make you go via layers of screens on your computer. Some kernels will enable you to arrange the CPU clock speed during installation. You may then make alterations every now and then via the CPU manager app you installed
  8. Clear cache after successful flash of kernel.
  9. In the Advanced settings within recovery, select ‘Fix Permissions’
  10. Reboot your system.

Changing your CPU clock speed

If the CPU setting were left unaltered during installation of custom kernel you’ll now be able to easily launch your kernel app. Or, find an app in Play Store if you do not have supported software as yet.


I’m currently using kernel adiutor, which is a free app. You’ll need to provide with it permission and installation of BusyBox.

Watch out for settings that authorize CPU clock speed. Either pick a max CPU speed from a drop down menu or use a slider. Do not forget to go through the whole process calmly and evaluate and analyze each clock speed and how it affects heat and battery life. Move from lesser percentage and then upto 30 percent.


If the CPU does not immediately moderate to the new setting, it is probably because of overclocking. It will take some time for the CPU to work up to high performance due to change of max speed.


Minimum clock speed can also be changed but it has negative and useless affect on battery.

Upon the confrontation of irregularities with your moderate settings return and decrease your clock’s speed by just a bit to notice the change.
