Hi guys,

I'm not sure about this, but my MBP 13" is quite new, I bought them nearly a year ago in October. But battery has been doing weird things. Maximum battery charge is normally at less than 1900mAh. But sometimes it changed itself to over 2000mAh. And so I thought it's odd for such a new laptop. So I decided to calibrate the laptop. It went down to 5% left or so and then telling me that I'm running on the reserve battery power. And then something magical happened, I suddenly have 61% battery left again... And the max battery charge is now 5162mAh.

This happened to me before too when I was not running on AC power when I was in Heathrow recently. It was nearly dying when it boosted up again. I'm wondering if the sensory thingy isn't doing well, or is it because I don't use my MBP unplugged often enough?

Thanks in advance for all the help and replies.
