Phone Goes into Deep Sleep, Still Burns through Battery
I did a search and found similar threads, but it seems that my problem is slightly different.
I have been using different CM9 Roms over the past few months and they have all been pretty stable, and the battery life has been pretty good.
However, I was on a trip last weekend and all of a sudden, my phones battery went from 100% to 40% in a matter of hours with the phone screen completely off.
I tried flashing other ICS ROMs, installing the blue sleep fix to no avail (wiping in between each, even doing a fastboot wipe as well). Then I restored a nandroid I had of a CNA ROM where I knew I wasn't having any battery life problems, but the problem still persisted.
I installed better battery stats to see if I could get an idea of what could be wrong. For example, this morning, my phone was charged to 100%. I took it off the charger, and it literally sat on my end table for 2 hours. I didn't touch it. I then looked at it, and it was down to 80%. I went into better battery stats, and it said under the partial wakelocks that the longest wakelock was only a few seconds. I then looked at the processes, and it said that deep sleep was the dominant process at 1 hour and 45 minutes.
Obviously if the phone is in deep sleep it shouldn't be dying that quickly (I would assume). Is there anything that anyone knows might be wrong with my phone that it is killing the battery across all these different ROMs?
My only other option is to completely wipe the phone and sd-cards and install nottachtrix, since I was getting 2 - 3 days of battery life on that ROM.
