Sudden huge battery loss while in sleep mode.

Okay, this one has me stumped. I woke up this morning and powered up my PC, of which my Hero is tethered to on a daily basis when it's not in use to maintain a current charge. I checked the battery icon and noticed that in the 7.5 hours I was asleep, and it in sleep mode, it went from 100% down to 77%. I rebooted the phone and now the battery read 84%.

Usually, when it's in sleep mode for that amount of time without a charge, in sleep mode, it would read the battery at about 94-96% (I have turned off all push notifications, syncing, etc), which I feel is pretty good. This is a first.

What could be causing this phone to suddenly have a battery drop like that? I haven't changed anything in the phone since the last (many) times the drop has only been a few percentage.

Mine dropped drastically too one day. Just had it in my case on my hip, and I felt it getting warm, took it out, and the battery was drained almost all the way. Level dropped from 65% to less than 10% inside of two hours. I just turned off the phone, restarted it, and plugged it in to charge. Hasn't happened since, so I chalked it up to roaming issues. Maybe a cell tower was down at the time and it couldn't do anything but roam.

Sometimes rogue apps drain your battery in the background. A fresh boot usually takes care of it.

Actually, I don't have any rogue apps on my phone. Only I installed on it was Zedge, AIM, and MSN Droid. But, the last two are never signed in, so I ensure they're exited fully.

I think he just means that it could be any app, stock, or user installed, that simply is not working properly, or is running when it isn't supposed to be running... aka rogue app.

I'm bumping this because I'm hoping for a few other answers. This morning, my phone dropped down to 60% within a 7-hour time frame of being in sleep mode. I know it's not roaming because it is in a position that gets about 4 bars. AFAIK, there's no rogue app causing this and all my push and sync notifications are disabled. I've rebooted the phone but it seems to happen a bit too constantly.

Would my only recommended option be to reset the phone and start over again with rooting it and such? Or, should I go about removing some of the extra apps I downloaded?

Nothing? No one has any answers to this?
