3500mAh Extend Battery Life for Samsung Galaxy S2 // GT-I9100

Extending/Longer Battery Life with twice as much power for your Samsung Galaxy S2!!!

In this video I review the seperate purchased battery with 3500mAh (milliampere) that comes with an extra cover/shell for Samsung Galaxy S2 devices!

Please note that your phone will become thicker due to the huger battery and case, just to let you know bevor you may decide on purchasing such battery, because if you have something like a flip cover it may not fit any more!!!
