Woke up to dead phone again. Wasnt plugged in this time. Went from close to fully charged to 17% in 6 hours when I turned it back on after battery pull.
Some Google-fu reveals that the phone coma/deep sleep is a known problem on this phone. Root or no root, Voodoo or no Voodoo. Long thread in the Galaxy Q&A forum on XDA. Happens to some people several times a day, others rarely, some claim based on location, some say phone was completely fine for weeks (like mine) then started acting up. Some speculation that it had to do with the phone draining its battery looking for data, or something with the battery management. They say the phone is just stuck, not dead, you can hold power button for 10sec, no need for battery pull (haven't verified this myself). Possibly some background process with mobile data locking the CPU. Some people fixed by toggling their APN off. Allegedly cured in Froyo. Some say going back to TouchWiz helped. I did a battery stat wipe in cwm just for shits. Also took off the traffic exception in Juice Defender so it shuts my data off even if something is syncing. I don't know if that will really help.
Anyone know if *228 will cause any problems on a rooted/oc/voodoo phone? doesn't seem like it would but never hurts to ask...
