What is Overclocking in Mobile Phones

In the digital age, there is always a need for faster processing speeds. With introduction of new processors in every next month impacts the mindset of users. A piece of hardware bought a few months back becomes slow today (in respect of faster one) . One way to overcome this short is by overclocking your mobile device.

Overclocking is basically running the device processor at a higher frequency than is designed by the manufacturer. The concept of overclocking a CPU/GPU in case of a PC has been for a while, although its new for handheld devices.

Most processors are multiplier locked i.e. they can be overclocked in steps of a fixed multiplier. In case of Windows,  overclocking can be achieved either by changing settings in BIOS or by using third party software like CPU-Z. For a smartphone, overclocking is more complicated. Most manufacturers don’t allow their devices to be overclocked, exception to the devices running open source OS like Android or Meego. However, overclocking a device would mean voiding warranty provided by the manufacturer, overheating of the device and reduced lifespan of hardware.

  • Increased performance
  • Getting more out of a budget product


  • Increased heating of the unit.
  • Voiding manufacturer warranty.
  • Due to overheating, the lifespan of processing unit reduces considerably.
  • Possible ‘frying’ of the microchip.

The performance gains of overclocking are great but one must be willing to take the risks involved.
