Ordered a 1500mah OEM HTC battery today for the Incredible, this is the battery for the Touch Pro 2 as touched on in other posts. This battery fits the INC, 1500mah is only about 15% more capacity than the Inc's 1300mah, but seeing as my Inc is down to 18% after a full day of use, maybe I can stretch it to 30% at the end of the day. I purchased from a reputable website, rather than ebay, because ebay is full of fakes and frauds. I plan on updating this thread with my findings as soon I get a chance to put it through it's paces. BTW here is the link I used.
