So.. I bought the cheap Chinese 3500MaH battery from eBay. No complaints... at all.... I can run the GPS, and several "unnecessary" apps all day long... and this thing is still at 60-70% by the time I go to bed. It's crazy.,.. I could EASILY go 2 full days with little regard for my task killer at all if I wanted to.. But.... My original hard rubber cover OBVIOUSLY won't fit over the back. I want the protection... so my only option was to literally cut out a gigantic rectangle on the back side on my cover... almost the entire back side of it.... so I really only have protection for the outside edges. And..... It looks terribly "ghetto". I've looked.... but have not been able to locate a suitable cover for my gigantic battery on my EVO. Does anyone make one?
