Hello,

Back in August 2009, I purchased my first Mac...a Macbook Pro. Six months later, I have to say this was the best purchase I have ever made. I love the Apple operating system.

Well...

I just performed a battery calibration on my Macbook Pro.

Prior to the calibration I was getting 6.5 hours on average for a full charge.

Now...in my first use after calibration I got 4.5 hours on the full charge.

OK...please explain this to me
