MBA 3.1 Battery life problem

[555shoe]

Hi.

I'm newbie here, so sorry if someone answered my question, i searched but don't find.

I've an MBA 3.1 bought in April. It works perfectly on SL, after I install the Lion, it works perfectly too, but the battery time fell down from 5hrs to 3hrs, I said ok, no problem, I love the new features. But yesterday I installed the 10.7.1 update (I trusted it will solve the battery time problem) and now, after 1.5 day with the update the iStat Pro widget says the battery Health is only 94% (it dropped down from 99%).
Somebody has the same problem? Or somebody know whats the problem?
I hope it just a software problem, and my battery is physically ok...
Please someone reassure me, I'm worried.

Thanks

I wouldn't worry too much about the battery health. Software meters aren't 100% accurate and those numbers tend to fluctuate. See if 10.7.1 helped your actual battery life, and if it did, don't worry about the meter until it drops into the mid 80s or below. Often, the meters will make what appear to be sudden drops and then stay there for a long time.
