Same here, went to the app store yesterday but no joy. They confirmed (ifactores) the battery wasn't working as it should, but on doing the battery test it cam out green. Barely green, but still green. This meant the could not exchange it under the warranty.
I Called Apple support to see if they are willing to help me, but that was a big no. The guy said that the equipment is not what is used to be and charging the battery to less (full cycles) will damage it just as much as it would when recharging to many. He also told me I should consider Apple Care... but that wear and tear of the battery was not supported by it...
He mailed me a document that explain the policy of apple when it comes down to Batteries and it says that (after 6 months) the the battery should still be able to recharge and hold a current. if it does that, the battery is seen as working (as long as it passes the test of course).
I asked if they could check for know issues, but they couldn't find one... strange since almost all the problems happen with the same battery type (ASMB012)
Strange thing with me is that the "service battery" is not shown all the time... When it does, the max charge will be below 4200 mAh... My life time is now doen to 1.5 hours...
I've tried resetting the battery and the PRAM, nothing seems to work.. Let's see and wait what apple will do. In the mean time, if you have this problem... report it to apple. If the number of complaints go up, they can't deny it (i hope).
