How do I fix this? [battery content]

[petrucci666]

My battery seems to last less and less everyday (around an hour an a half on a full charge) and I don't want to buy a new battery if I don't need too. I remember when I could easily get 4 (maybe even 5) hours out of my battery. Would battery calibration help me fix this and make my battery healthier? Just a week ago it was at around 88-89% now it's down to 66%

Thanks

Hmm.. well if it drops below 80% capacity before 300 cycles you have a problem. It couldn't hurt to go here and schedule and appointment to have it checked out.

Try calibrating it, that may help. If it doesn't, then you need to get take it to Apple.
