For me, I may charge rate was substainly better and about what I would
expect. I drained the battery to ~20% and then charged it back my
default setting of 98% in 2 hours 13 minutes, which is about what I
would expect.

Scott, on your next charge can you run:
while [ $( awk '/charging state/ {print$3}' /proc/acpi/battery/BAT0/state ) =
"charging" ];
do
date
cat /proc/acpi/battery/BAT0/state
done | tee battery.log
When I was having the problem, I was seeing charge rates as low as 10 or
15mA.
