Samsung current flagship model, the Galaxy S3 is a great phone. With Quad-core 1.4 GHz Cortex-A9 CPU and Mali-400MP GPU the phone is quite a battery drainer. Thought some may argue that having a 2100 mAh battery does the trick, personally as an extensive user of my phone, I feel it’s a bit shy for a superphone. Bearing this in mind Samsung has decided to launch an official extended battery pack. This is currently available on pre-order.
