I've been noticing (especially since a little after the GB update) my battery dying very quickly... sometimes not lasting more than 6 hours of moderate use.

I started reading threads here, there, and anything a google search would bring back. Apparently the battery drain is caused by the system's suspend process going rogue. I installed the full version of System Panel to monitor my usage, and sure enough suspend was taking up a lot more cpu cycles than anything else on my phone.

From reading further there isn't any specific phone setting/app that can fix this bug. Then I read something interesting... someone said that they only see the problem if they plug their phone in (usb or wall charge... doesn't matter), then unplug it without a restart.

Since I sit at a desk all day I frequently plug my phone in (nandroid backups, moving files to/from my sd card, etc.). I decided to do a test. I already have Tasker kill my ringer when my phone is plugged into any usb, so I added an exit task to reboot the phone when I disconnect usb.

I disconnected my phone from usb, and it restarted automatically... exactly what I wanted. Since then I haven't seen suspend do a damn thing. I have turned wifi on/off, killed data sync/turned back on, etc... all the things people have tried to fix the issue. Still nothing over the past couple of hours for suspend.

I will continue to monitor... so far it looks very promising.

Yeah, I'm betting that will work just fine. I've been seeing it go nuts after being plugged in for a while and did mention it in another thread. I was suspicious of suspend but hadn't had enough time to be sure. Now that I know its that well have to see if there is a more elegant fix than restarting every time we unplug. That does work though. Good job point out the exact problem.

What are you using to auto reboot when u-plugged??? I can't find that option in system panel or task manager.

I tried the reboot trick and im going on 16 hours at 70% battery. Plus system panel shows cpu under 1% when device is suspended.
