it fluctuates, ive had mine since april last year,
mine was low but once i did a few cycles in a short space of time, it became more accurate..
how many cycles have you had?
mine is around 93-95% after 180 cycles

Seems normal. I know there is an unofficial warranty on batteries if it dies before 300 or 600 cycles. Can't remember which but I've had it happen twice, outside of applecare and the batteries over a year, and they were replaced no problem.

Ouch.. Mine's 22 months old, 199 cycles 94%.. If 36 more cycles will drop my life to 85% that would suck :(

Battery Health is not linear. It'll jump around. Stop worrying. Only start worrying if it drops under 80%, then visit an Apple Store and tell them.

That said, you should use it a bit more.

I'm at 270 Cycles in 5 Months Ownership. 93% Health currently. It was at 89% and yesterday it was at 95%.
