Android How To: Overclock the T-Mobile Samsung Galaxy S4

Before we continue, we must warn you that overlocking your device can harm your device and if you’re not rooted you will not be able to overclock it. So as usual, Android Headlines is not responsible for any damage caused to your device. Also be sure to read this entire guide before attempting to overclock your T-Mobile Galaxy S4.

What is overclocking? Well Overclocking, is making your processor run faster than the manufacturer wanted. Often times, I underclock my Nexus 4, to about 1GHz or 1.2GHz, which gives me better battery life along with no lag. Some people want to overclock their device, just to see how fast it goes. In fact, just last week we heard that someone overclocked the Exynos 5 Octa in the International Galaxy S4.

Now because you can’t usually overclock the stock kernel, this guide is in two steps. First flashing the kernel, then overclocking it.

What you’ll need

  • A rooted T-Mobile Galaxy S4 with CWM or TWRP recovery installed
  • A custom Kernel (you can grab one from the T-Mobile Galaxy S4 forum on XDA)

How to flash the Kernel

  1. Place the kernel you downloaded onto your device. 
  2. Reboot into recovery
  3. Using the volume buttons (unless you have TWRP recovery) select “install zip from SD card”
  4. Next select “choose zip from SD card”
  5. Select your Kernel
  6. Then confirm you want to flash that kernel.
  7. Once the flashing is done, hit reboot.

Overclocking the Galaxy S4

  1. You’ll need to go to Google Play and download an app to overclock. Any of these will work: SetCPU, AnTuTu CPU Master, Franco Kernel Updater, etc.
  2. Once the app is installed run the app
  3. Under the processor section, tap on the maximum CPU frequency
  4. Select the frequency you want your device to run at.
  5. That’s it.

As we said already, overclocking your device can do some harm. But most people don’t keep it overclocked for long because it’ll heat up and the battery will die rather quickly. Also this does void your warranty since you do have to be rooted to do this.
