Hi all,
I'm new to the forum. Just bought the Lumia 3 days ago. I would like to say that I really like wp7! The hardware of the phone is second to none imo. The lumia's curved screen is amazing!!! The OS is extremely smooth and have had no problems. The only let down is the camera (although I read its a software thing).
Regarding the battery life:
Mine seemed to be ok, leaving it on standby and using it occasionally resulted in a full days use easily. Downloading the update as we speak and will let you all know of any improvements.
