Overall, since mid-November, my Droid Bionic with 4.0.4 has been working great after I did a clear system cache and got most battery-drain issues adjusted (off). On three occasions, though, my battery has gone from 60-70% to 0 (and turns the phone off, of course) in a matter of an hour or two just sitting doing nothing. Once I plug it in and give it a few minutes, it will let me turn it back on, usually showing about 5% charge. Here's the strange part though - it will totally charge to 100% in an hour or so. (Normally, going from 20% or so to 100% would take 3-4 hours.)
Specifically, one time this happened was mid-day on Nov. 20; another time was at about 8:00 PM on Jan 16. The third time actually happened overnight Jan. 2 or 3. Obviously, I can't say for sure how quickly it drained that time, but it did charge back up more quickly than normal, like the other two times I had this quick battery drain. (My normal overnight battery drain has been fairly consistent at only 10-12% since mid-November.)
Any ideas what could be causing this sporadic issue?
Thanks!
