Battery life dropped by 50%

[knmlee]

Battery life on my MacBook Air (1.86/SSD) has dropped to less than two hours (for casual web browsing). When new, I got more than 4 hours on a full charge. Also, the battery meter seems to be way off. The machine shuts off with the meter showing 40% remaining. I've tried several full charge - discharge cycles. System information shows battery health to be good.

Any ideas on how to get battery life to where it was when new?

Out of curiosity, has anyone had their batteries replaced by Apple? How much would that cost?

Thanks

I would first tryab see what the utility coconutBattery says about the status of your battery. If it is still acting up I would bring it into an Apple store as they'll likely replace your battery for free if it has been acting up.

Interesting utility (coconutbattery).

It shows that my current battery capacity is only 67% of the original. I wonder what happened to cause that? My machine is only 4 months old.
