the problem with WM phones and battery drain is more service related than programs. the phone spends so much time polling towers, finding best non-roam service, switching data-voice that whenever it needs to call out, it turns on the screen. whenever it looses signal, it turns on the screen to let you know its searching. all these popups in WM wake up the phone, and along side with the overworked radio, they kill the battery.

i bet you, if you left your phone on flight mode and left it on standby, it would last a week (im not exaggerating, my touch lasted that long, if not longer with the stock battery)

going back to your problem. maybe where you were, you may have had spotty reception therefore waking the phone from standby to alert you its looking for a signal. or the case you have on your phone choked out the antenna

ps: i know this because ive experienced this first hand. i used to bring my sprint touch to work, where verizon's signal is superior, and my touch actually flips out whenever it finds a weak sprint signal and attempts to hang onto it with death-grip effort. the result? my phone will last 4 hours at work unless i put it on flight mode (this has actually locked up my phone to a useless crawl a few times, even where sprint offers full native coverage. no way to fix it other than a hard reset)
