So first off, I absolutely LOVE my MBA. Now that we have that out of the way...
Since day 1 I've noticed that the cycle count on the battery seems to be climbing MUCH faster than it should.
-- I've had the machine 51 days. I was out of the country without it for 9 days so really, I've had it for 42 days.
-- According to iStat and System Profiler my battery's cycle count is 37
-- According to System Profiler my battery's health is "Good"
-- According to iStat my battery's health is at 98% (It started around 96%, has been as low as 94% but seems to have settled in at 97 or 98% for some time now)
-- According to system profiler my maximum charge is 5006 mAh. (It's also gone up a bit since the machine was new).
I thought the definition of a cycle was the equivalent of 100% depletion of the battery -- whether that's one long unplugged stint that sucks it dry or 10 really short ones -- a cycle is the same as using ~5000 mAh of battery power.
So here's the thing. I've been REALLY good about keeping it plugged in while I work (the outlet is conveniently located). I've run the battery most the way down maybe 5 times. I do, however, run it down 10 or 20% almost every day as the machine travels with me in sleep mode or spends the night unplugged in sleep mode at my girlfriend's place)
I haven't done any careful testing but it seems though that if I run the battery down just 20% or 30% or so and then charge it all the way back up the cycle count increases by 1.
Considering I've only used it for 42 days, and the cycle count is already at 37, I'm worried that it will hit 200 cycles by the time it's 8 or 10 months old. Isn't the point where battery performance starts to wane?
Anyone else out there notice a rapidly climbing cycle count? Any suggestions or ideas?
Oh yeah, and I love my MBA.
