has anyone had issues with the battery life of their T mobile Pulse? I purchased mine in Jan 2010, and instantly loved it< fab phone and the battery life was OK, when I say OK it lasted about a day and a bit with reasonably heavy use. Then it went to a day, then 10 hrs, then 8 then last week, after leaving it in my pocket in a locker whilst I was working out in the gym (lucky it was in its little case that T mobile supply) it decided to discharge its battery and get very very hot in the process, gave me a shock when i put me trousers back on I can tell you!!!!. I took it back to the shop and they have sent it away saying that they couldn't replace it for a new one straight away as it was nearly 2 months old. Thinking about it if I had more time I would have argued that. Anyway I do miss it, and wonder if anyone else has had similar issues.
