I've read lots of conflicting information about this subject. Most sources I am seeing via Google search say that after 1000 charge cycles a lithoum-ion battery, like the one used in the macbook air, will no longer hold a good charge and will basically be worthless. Yet, Apple says that after 1000 charge cycles the battery will only lose 20% capacity here http://www.apple.com/batteries/notebooks.html.
Is this really true?
Since I purchased a Haswell MBA the other day does that mean after 1000 charge cycles that I am really going to still have roughly 9.6 hours of battery life? (12 hours X 80%)
Also, what happens after 2000 charge cycles? Do I still only lose another 20% to 7.2 hours of batter life give or take? (12 hours X 60%)
Any expert opinions on this subject would be greatly appreciated. Thank you
The built-in battery of your MacBook Pro or MacBook Air is designed to deliver up to 1000 full charge and discharge cycles before it reaches 80 percent of its original capacity.
