I recently upgraded my Samsung I5800 to Android Froyo 2.2 (I5800XXJPB) with ODIN. Since Samsung hasn't release and update from Eclair officially, and from the likes of it, they might never. My battery seems to drain everyday since the upgrade and I have to keep recharging. I spend like 10-15mins on the phone talking, and the battery icon becomes red after. I've even taken off "Background Services and Syncing". I can't see how a phone can drain so much power in such a short time. I was reasonable in Eclair. Is there something in Froyo 2.2 that is affecting the I5800? Did I miss something? Can this be fixed in someway while keeping Froyo?
