2011 Battery

I know there have been numerous battery threads but I wanted to see if this specific thing is happening to others....so I have charged up and let my battery die then charged up again, at least twice now....I find that my battery at first says 5-6 hours remaining or so, then drops to 4 after a couple hours, then after a few more hours goes down to about 3:50, levels at that until about 40% remaining or so then goes to 2 for a couple more hours, once I hit about 1:30 left I can last another 2 hours at least.....

Does this battery need to learn a pattern or something? seems like I get at least or more than the 7 hours as advertised, but the distribution of time remaining is odd.....my 2010 MBA didn't seem as drastic as this, and I could always get it to start at like 11 hours remaining....

Time remaining is a poor way of displaying battery life as it is dependent on usage at the moment the time remaining is calculated. This has been explained over and over on these forums.

Yep.

Takes a couple cycles of the battery to get more accurate.
