MBA 4 days old battery issues


Just bought a MBA 13" 8GB 128GB.
Awesome little machine. Really happy with it so far.

However, just noted my battery health is 98% sometimes 97%.

Is this normal with a shiny new machine ?
Just read Apple's advices on batteries, and did a callibration: drained the battery until shutdown, wait 5 hours and fully recharge, but it doesn't seem to solve it.

Also, the estimated time for battery is just 5 hours. I have just the Chrome opened, brightness to 1/3 and no backlit keyboard. Apple claims 7 hours on the 13".

Do you think i should return mine and ask another MBA, or im just freaking out for nothing?

It's nothing man.
The battery life indicator is unprecise so basically you're freaking out over nothing but I remember it myself too when I bought my first mac - an MBA - a year and a half ago.

Don't expect to get 7 hours of charge out of your MBA though unless you're being very very conservative of your use.


Just enjoy the fantastic new machine you've acquired! =)
