Hey guys, I just bought a MBA 13" I5 3 weeks ago and experienced a significant drop in battery health. I started with 98% according to Coconut and IStat which was strange to beginn with but then it went down to 93% and is now at a constant 95%. I tried recalibrating it twice but it doesn't really help. Furthermore Coconut says my battery is already 28 weeks old which also makes me wonder... Anybody experiencing similar battery health/age?
