show me your
~# lshal | grep battery.reporting
(in xterm or via ssh)

What I notice is that my battery.reporting.design is increasing after using the device now for 8 days (1260 -> 1275mAh). I also notice that I never reach the design capacity after overnight charging. I reach a quite constant level of 1220mAh.
Meanwhile my device last longer than a workday, longest running session was 18h and then I still had 10% remainig capacity.

Bye
