Upgraded iPhone 4 Battery?

[d4m1r]

Hey guys, I am wondering if anything like this exists....An upgraded battery that fits inside an iPhone 4/4S? I still get a decent charge and I know an OEM replacement is possible, but I am wondering if I am already at it, if any aftermarket solutions are out there to extend my battery life further over the OEM one?

Let me know!

those juice packs are the only option I know about never really researched it but I am sure my parts suppliers would have offered me one if there where such an option.

FYI, it looks like it is NOT possible to buy such a product currently....You can buy replacement OEM or even 3rd party batteries for really check these days (under $10), but they all have the same charge capacity as the stock battery
