Gave up on CM10 with the Fire
As much as I hate to say it, I had to flash my Fire back to the stock rom. I had CM10 on it, and it was fantastic. Except for the battery life. 2, maybe 3 hours was all I could get out of it. 24 on standby.
So, i think I'll just have to bite the bullet and sell my Fire and get a Nexus 7.
It's too bad, really. I like my Fire a lot. But Amazons custom Android sucks, and I really want the play Store.
So, unless anyone knows of a Jelly bean rom that has decent battery life on the Fire, I have one for sale. Cheap. Only $189.......
