too many posts to read all of them, but here is my take
i'm sure there are some legitimate battery issues, since nothing is ever made perfect so some of you out there with short battery life should definately look at getting a replacement. probably just a defect, it happens.
now, i also think there are some people who have just unrealistic expectations for the phone. i just don't understand how anyone can expect a phone (doesn't matter which one) to last all day without a charge if you are browsing internet, listening to music, and making calls in between all of that, and doing that fairly consistently all day and still expect the battery to be good at the end of the day? to put it in perspective, would your laptop handle that kind of a load? i don't think so, or any other device for that matter?
as for all those who comment about being at work and not being able to charge the phone, well my question to you is, why are you using your cell phone that much at work? shouldn't you be doing your job and not browsing the internet on your phone and listening to music? i'm not trying to pass judgement but logic dictates that the question be asked
when i'm at work, i carry my phone with me and i answer it and make calls all day, i leave all the services turned on, and by the end of the day my battery is fine, easily more than 50% power left on it. so i think if you are having power troubles you may want to exchange it.
another thing people need to understand is cell signal has a lot to do with battery life too, if you are always in an area with poor reception your battery will drain faster because you force the phone to constantly search for a signal, even when the phone is on standby
as for the comment about power leaking on standby, it isn't a leak, it is normal, why wouldn't power be used when a phone is on standby? it still has to maintain it's radio reception to hte cell towers right?
