I had been using the old ROM 2.1 it was ok except for the Battery life. Yesterday by 7pm my battery was down to 20% after regular use. with 1.8 at the same time and use I would have around 60%. Last night I updated to 2.1 and i'm happy to say that I've used my phone more than regular today. and Now its 4:30 and I have 80% I'm impressed. Good work guys!!!
