I'm trying to determine how much better my battery life is based on non-scientific normal everyday usage. I installed Sky Raider 1.9 on my phone. Charged two of my extra stock 1300mAH batteries to 100% and have been running them on the phone. Will restore back to my stock ROM and try the same and see the difference. What have you guys found? Aren't we supposed to see improved battery with Froyo?
