Uhhhh... There's so much wrong with that statement, I'm not sure where to begin... So I'll just skip it.
Most of what people are having an issue with here is likely 3rd party apps... and if it's not 3rd party, some of the RIM apps do draw a hefty amount all by themselves... maps is a good cuprit if you leave the GPS enabled, easy test is to turn off ALL GPS features from the Advanced Options menu, run it for a day and see what happens.
If you've got only 4 hours with a bare-bones OS load however, and the phone is hot, there's a constant network connection running most likely... the radio in use is what warms up a phone fastest. If you did your OS upgrate OTA, might I suggest downloading the PC install, and doing a full wipe and reload. Chances are something is "stuck" in the software load. personally, with each new OS, I wipe my phone down to spec. and restore my contacts, calender, bookmarks, themes, and 3rd party apps afterwards3rd party apps I usually download fresh from the app store or the creator web sites, just to make sure I get the latest version at the time too.
At any given time, I run:
A Personal Assistant
The Hockey News
I leave NOTHING open once I finish using it.
On a heavy email/sms day, I make it 12 hours, BUT I also use it as my MP3 player for that whole 12 hours as well.
The phone wasn't really build for longevity with a 1400mAh battery... That's a pittance when it comes to connectivity, and that big beautiful bright(brighter than the iPhone i might add) screen. I carry a spare battery when I'm out of town. I've a cradle in the car, the bedroom, and the desk at work(Pretty much only use my bedside though)
One last note... I upgrade faithfully every time an OS update comes out, and the one thing I've noticed, is that aside from the major changes to things like cut/paste(thank doG, the pre-121 was deplorable) is that the network speed was drastically increased... Currently I average 400Kb/s to/from the handheld, before 121 and later I was lucky to break 100Kb/s.
