So I have a 7 month old MBP.
Within the past month, my battery capacity has plummeted. At the end of December/beginning of January I was getting 3ish hours of battery life. Since then, and checking coconutBattery, my battery now gets less than an hour and has 48% of its capacity.

I know I haven't calibrated it often enough, so i'm running through that a few times to see if it gets back up.

I seem to remember some warranty issue with batteries. If they lose a certain amount of capacity within a certain amount of time you get a free replacement?

Any other suggestions?

Should be at 80% capacity at 300 cycles.

Two months ago, my battery was at 54% at 300 cycles EXACTLY. I took it to the Apple store, and they exchanged it. It was a painless process.

Apple will replace for free your battery without problems... On december I had your same problem... call them!

Same here, just last week actually. Got a new battery from Apple after my battery dropped to 64% after 52 battery cycles.
