Help Samsung Infuse won't 'idle' correctly

I have had a problem come and go with my Samsung Infuse. Some update from some app causes the CPU to never be able to truly 'sleep' or 'idle' correctly causing the phone to burn through 3.7% battery life per hour. When it's 'healthy' it only uses 0.7% per hour.

In the past I thought I had isolated Google Play Books as the culprit and uninstalling that solved the issue. It took me quite a while to find that issue, then my phone was great for months. About a month or two ago something changed and the problem is back. Again I uninstalled almost all updates and apps I didn't need and managed to get it purring nicely for over two days, then it started burning power again. Any help would be greatly appreciated as I am sick of fighting with it and also do not want the pain and expense of a new phone as that seems the only option.
 
I installed WLD and after 2.5 hours running, my battery is now draining at 4.5% per hour with something called UID taking 3m 18s for a total of 29 times and only four other listings adding up to less than half of that in wakeups and less than a minute. Net was 3% awake.

How is my phone burning so much power if it's only awake for about 4 minutes total???

My phone is NOT rooted, not sure exactly what that means but I am assuming some kind of wipe and re-install without ATT junk on there. I suppose rather than buy a new phone I can look into that process, would that let me get the latest version of Android? I assume I would lose EVERYTHING I have configured on the phone, would I still be able to use it as an ATT Go Phone? It took HOURS for the techs in the ATT store and help from experts on the phone to get data working on it and I would hate to go through that again.
 
Wakelocks are not the only cause of battery drain. Check BBS for the full picture. Or, if you want to try a slightly less capable (but free) alternative, try GSAM

Oh, and 2.5hrs is not really long enough. Try leaving it running overnight, or better yet, all day with typical usage. GL!
 
I did leave it running overnight, and BBS tells me I currently am at 91% deep sleep and 5% of the awake time was screen on when I was using it.

What's really strange is that for the last 5 hours two battery apps show me locked at 30% battery power which makes no sense. It's like the phone has no idea how much power is actually left in the battery. Is it just voltage that tells the phone how much battery is left?

I have played around with a few 'battery' calibrators in the past, but at the time they didn't seem to do much good. Is that what I need now?
 
Good point; maybe it's time for a battery recalibration. The thing is, you need root access to delete the file, /data/system/batterystats.bin. If you have root or are willing to root, its a simple matter to delete the file, fully charge the phone, then fully (or almost fully) discharge.

It might be possible to overwrite the file with an empty batterystats.bin (without root), using ADB 'push' from a computer. I have no experience doing that though, so can't advise you further.
