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.
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?
