I purchased an Atrium about a month and I am very pleased with the phone except for the poor battery life. When I check battery usage 'Phone idle" usually. is the biggest consumer. It is really annoying to have to charge my phone 3 times a day.
Send an RMA request to get another battery. I had a similar problem however not as bad as yours and they sent me a new battery. Battery life is a problem with these phones so having 2 will help. Also having a portable usb power pack around is handy too.
I have not had an opportunity to download the new ROM. I will let you know when I get a chance
