2011 MBA 13/4/128. I've only had it for less than 3 weeks. I've done two calibrations. iStat and Coconut both report that it's now at 96% health and 7 cycles. I've read through the battery faq's but 96% after only 7 cycles doesn't seem right. Everything else is working great so I'm reluctant to return it to Amazon for a replacement. Am I overreacting or is that more than a normal drop in 7 cycles?
