Hello,
I`ve just bought a macbook pro 13" aluminium. it`s my first Apple device. But I have a problem that I cannot solve.
When I charge my macbook, it indicates 100% loaded. However, when I disconnet off outlet, it shows 99%... Is it normal?
Thanks a lot,

That is normal.

Newer batteries do not need calibration.
Best.
To avoid overcharging - a bad thing with Lithium Ion batteries - once the battery is fully charged the charging circuitry stops the charging and lets it discharge a bit before turning the charger back on. Think of it as a trickle charge. So yes, this is normal.
