Battery Problem?

When I first got my Macbook Pro replacement last week, when I would charge up to 100% battery, then unplug, it would drop 1% at a time as the battery was used up. Now when I charge to 100% and unplug, within 1 minute the power jumps from 100% to 96% all at once. Then from 96% it goes down 1% at a time until it runs down. I've tried to calibrate the battery. I'm not sure what else it could be. Does anyone else have this issue? Is there something wrong with my battery? Thanks! :)

So I'm not the only person experiencing this issue? I've tried searching for others talking about this and can't find anything. The only thing I've found is people talking about the battery capacity jumping around as opposed to current battery life that I'm experiencing. What is also weird is that when I click on the battery % at the top, it says fully charged when it's displaying 96%. That makes it even more confusing. I really think something isn't quite right. I was just curious if anyone has seen this before. Thanks.
 
That happens because Apple only lets the battery charges when the computer hits below 94% battery life. If its higher than 94% it wont charge, but if its lower than 94%, then it will charge all the back to 100%. It's a feature to maximize the life of the battery (according to Apple).

By the way, you're the person who spilled water on your new computer and got a new one for free? Nicee.

Hope you're enjoying it. I just got my Macbook Pro too.
