It is a well known fact that the battery life of the htc desire hd is pretty lax, after having my phone for a month ish it hasnt overly bothered me. But i just thought i would feel more comfortable if i did have to think about my battery level during the day. I had a look for a longer battery but its really hard to know like what capacity i would need and if the battery will work etc. So if anyone would be able to point me in the right direction that would be great. thanks
