The Apocket B1100 is an ultra-slim battery case for your iPhone 4

Since Apple won’t let users change their own batteries for their iPhones, companies have taken advantage of this fact and produced their own battery accessories for the iPhone. Seeing how the iPhone’s back cover can’t be easily removed, companies have resorted to creating cases with batteries attached to them. This has lead to the creation of large, bulky and unsightly cases- a far cry from the lean, sleek machine that the iPhone is supposed to be. Well OTAS plans to change that. The Japanese company has added a new ultra-slim and light battery for the iPhone 4 in its latest catalog. The Apocket B1100 improves your iPhone’s life by an additional 50% with its 1100mAh battery, but only adds 15mm and 51g to the phone. And the icing on the cake is that you can now sync and charge your iPhone using any regular micro USB cable with the micro USB port at the bottom of the case. How’s that for convenience? The Apocket B1100 will set you back $48 (3980 Yen) and can be purchased here.
