Hi

my brand new MBA bought this summer had 97% battery life right after unboxing it

now after 30 recharge cycles, it's down to 95%

is this normal ?

it's measured with istat nano, so is this accurate or should i ignore this figure ?

thanks

It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.
