Found Out Why GB's Killing My Battery (with Temp Fix)
This morning I was finally able to isolate what was causing my extreme battery drain. It's "Enable Background Data". I disabled it, unplugged my fully-charged Pro and in exactly four hours it has only used 20% power.
If you don't have an unlimited data plan - and you're experiencing this problem - I highly recommend keeping a close eye on your data use because that's how I discovered the cause.
Normally, I use between 1.2 and 1.4 gigs/month. Post GB, my phone has gobbled up 1.1 gigs in the past SIX DAYS! My battery was also running red hot. After disabling b/g data, the temp has dropped over 10 degrees (my battery app measures exact temp).
Disabling b/g data is hardly ideal, but I'm sharing this in the hope that it helps some of you until a permanent fix is available.
