Overclocking was once limited to desktops, but it now looks as if smartphones are catching up as enthusiast DIYers start to tinker with the hardware.
Someone from XDA developers forum has managed to overclock the T-Mobile version of the Samsung Galaxy S II, which comes with a Qualcomm system on chip, from the standard 1GHz to a staggering 1.836GHz - that's around an 84 per cent speed increase.
The post on XDA-developers gives ample details how to achieve this spectacular increase in clock speed. At the time of writing, there were no benchmarks, and overclocking to such levels should be done very carefully because unlike their desktop counterparts, you can't cool SoC's using exotic cooling solutions or even a proper heat sink fan.
Furthermore, it would be interesting to find out whether a smartphone can sustain such high overclocking levels without damage, and what the effect on the battery life the overclock has.
It appears likely that Qualcomm's current system on chips have a lot of legroom, something that will allow the company to produce and label parts at different clock speeds more easily.
