HI, I've got the early 2009 MBP 2.66 Ghz, with a detachable battery.

Before it used to run for like 4-5 hours easy(medium brighness and keybord settings). Now it runs for only 2.5-3 hours battery 100%.
iStat showing battery 100 health(44 cycles) and in the battery info menu full capacity is 4686 ma/h.

What could have caused such a big difference in battery running time. (I mean, the capacity seems to be normal)?
