MBP 13 battery

jlk · 1 Feb 2011 at 21:09

Hi Guys!
I have a MBP 13 inch bought oct 2010 thats had 91 charge cycles. and the battery has started to run out much faster than it used to do. I installed coconut battery which reports that the battery is at 87% of its designed capacity after only 91 cycles! its now 5071 mAh out of the 5770 it shipped with.
Its fallen 3% in the last few days or so.
Should i contact apple about this or just wait until it hits 80%?
Has anyone else had problem like this?

thanks

Jon

Try recalibrating your battery before contacting apple.

Mine is 14 weeks old and is at 90% after 52 cycles, so you aren't alone.

I calibrated the battery a few days ago. Apple say the battery should be at 80% after 300 cycles, mines at 87% after 91! The main reason i bought it was because of the battery life which up until now i have been very impressed with.

It should still be lasting like 5/6 hours with 87% battery. What are you doing with it recently to make a noticeable difference? Lots of flash player?

Ive charged it with it shutdown today and its back up to 5350 which is better! Apple say it should fluctuate 10% so i am happy for now! Thanks for all the input.
