I discovered something interesting today...
I installed some custom ringtones to my SD card last night by creating a ringtones folder on the SD card and copying the ringtones into that folder.
I then selected one of the custom ringtones as my default ringer.
Today my battery was drained over 60% by 11am.
(unplugged at 6:30am)
Before adding the custom ringtones, I was easily making it to the evening hours without any battery problems.
I checked the battery status and was alarmed to see that my up time and awake time were nearly 1 for 1!
I rebooted the phone thinking there was a run away app. After being up for an hour, same problem, a 1 to 1 ratio.
The battery use indicated Cell Standy as number 1 with Android System as number 2.
I knew something was wrong as usually Phone Idle is number 2 in my list.
So, I deleted the Ringtones folder I created on the SD card and rebooted.
I checked the phone over the last couple hours and awake time an up times are back to normal, as is my battery use indicator.
Long story short, it appears that the system may have been staying awake to keep the SD card powered since my default ringtone resided on the SD card?
