I was using my computer normally, unplugged. On the top menu bar, it reads 36 minutes left of battery life. A few seconds later, my Macbook Pro shuts off. I know the meter didn't run out yet, so I press the power button without plugging in the power adapter. It powers up for a few seconds and then shuts down again.
I plug in the adapter and boot into OSX. The meter says that there is still 22% of my battery left. Very strange...

Is there something wrong with my computer? Is the battery not calibrated correctly? Surely, it can't read 22% when it's actually 1%, could it?
