The Sony Xperia S is a mid-range Jelly Bean based smartphone that was released way back in February 2012. So, the phone’s performances are not outstanding, meaning that improvements and upgrades are more than welcomed. Well, if you are looking into gaining more power from your handset, then use this guide and learn how to easily overclock your Xperia S. This tutorial will take you through the overclocking procedure therefore by completing the same you will be able to change the CPU frequency that is currently established on your Sony Xperia S.

Overclocking your Android device is safe, though before starting the proper operation you need to do a complete research. Of course this is an unofficial procedure, so if you don’t know how to properly apply the overclock operation, you might end up in bricking your Xperia S. That’s why you should first read the guide from here, which will explain everything that is related to the overclocking process – advantages, disadvantages, how to set the frequency for avoiding battery drain issues, and so on.

Now, on this tutorial you will learn how to: flash a custom kernel on your Sony Xperia S and then how to use a dedicated tool for increasing the power of your handset – by overclocking the CPU. The custom kernel is needed because else you can’t change the CPU frequency; by using a custom kernel you will actually enable overclocking on your Xperia S. Then, you will have to download and use a dedicated app which will provide an easy to apply overclock solution.

But for being able to complete the mentioned operations, you will first have to root your phone. You can overclock only a rooted system, because a custom kernel can be flashed only on unchained devices. So, gain root access and remove the factory restrictions from your Sony Xperia S. Do remember that the warranty will get void – you can restore the warranty by applying an official Android update (rooted handsets can’t be installed with OTA releases, the firmware must be flashed manually) or by downgrading your phone to stock Jelly Bean OS.

Furthermore, CWM recovery or any other custom recovery image is being required on your smartphone. Unfortunately, the stock recovery can’t be used when trying to overclock the CPU, so ensure that your handset is installed with a custom recovery tool. Do note that if your Xperia S is currently powered by a custom ROM software, you might be able to skip the custom kernel section. Usually the custom ROMs are also coming with custom kernels, so overclocking might already be enabled on your Xperia S; if not follow the steps from below and learn how to easily flash a new kernel on your device.

Don’t forget to backup the data as by completing the next methods, your personal info, accounts and data might get corrupted or erased. Also, if possible make a Nandroid backup for saving / restoring the current ROM. Ensure that a computer or notebook, your smartphone and its USB cable are near you. Furthermore, on your computer and device deactivate the antivirus – or any other security program – protection. Enable the USB debugging option on your phone and charge the battery in case there is less than 60% power left – if your Xperia S gets turned off in the middle of the overclocking process, you will risk in bricking your handset.
