I wonder if the battery charging issue is associated with rapid drain of the battery in normal use.  I posted on a different thread about runaway processes occuring after the update to Gingerbread

and I forgot to mention that a side effect of fixing that was that the charging speed increased.  I get full 100% charges now, and the phone runs all day in reasonable use (email, texts, calls) and is still at around 70% by bedtime.
