I found the battery of my iPhone 4 could not support my daily usage. I am thinking of get an external battery. After studying reviews at iLounge, I think the MiPow Power Tube 4000 is ideal as it is compact in size, with 30 pin connector built-in and got 4000mah battery. Have anyone tried and would recommened?
