If this is a real problem the HTC should have a recall on their hands. Im hesitant to send mine back (First UK batch) though, even though mine lasts little more than 10-12 hours while pushing email.
What do people think the faults are, the hardware, the ROM or the battery itself?
Im thinking this because many people who were early adopters with the UK/Euro HTC Diamonds are frustrated with a battery that lasts little more than 12 hours, some people (if they dont push email) a day. Others, particularly those who had the later Diamonds (inc the operator branded ones) are reporting 1.5 - 2 days of usage.
