macbook battery dies too soon

[furcalchick]

for the past few weeks, my year plus old macbook has been turning off really early, as in just today, the macbook timer says i still have about 15 minutes of juice left, then it just turns off with no pop warning 'you have little battery remaining, please shut off the computer'. it's just annoying that this is happening, even with my battery health at 100%. i would like to know if this is normal over time or if there is something wrong with the battery and what i can do to fix this. thanks.

here's my coconut battery analysis as of right now.

I've tried Coconut, and I do not trust it at all. First it said that my Macbook was charging, when it wasn't. And after a few days if use I noticed that it kept showing big decreases in battery life. I don't trust it.

As for your Macbook dying fast, I have no idea.
