***MAJOR UPDATE***
When I enabled b/g data this morning to allow the Pro to sync, 3G turned blue as usual, but the up/down arrows didn't light solidly as before when it always indicated the data churn had started up again.
I decided to leave it enabled. For some reason, the churn has stopped. Even though I did a soft reset - and later a battery-pull reset - the churn has not returned. The com.Motorola.service.main is also no longer locked.
I've been off the charger for 7 hours and still have 20% charge left. Device temperature has stayed between 80 - 95 degrees all day.
Here's the kicker; I didn't DO anything. The problem stopped on its own!
I wonder if Vz or Moto were doing anything on the back-end after I opened my trouble-ticket? No idea, but even if I get 8 hours out of my battery, I can live with it.
Now, I'll keep my fingers crossed that the problem doesn't come back!
(Sorry for posting in two places, but I wanted to make sure everyone with the battery-drain issue sees this)
The same happened to me. Must have been a back-end issue.
