Macbook Battery Problem

[polinho]

Hi there! I've had my macboook for 3 months now and I've decided to download a program that says how much of my original battery capacity is still available today. To my surprise, with only 3 months of use, it says that the full charge today will only go up to 86% !! Is this normal??

Are you using Coconut battery? Before you start to worry, charge your macbook to 100% and then run it down untill it goes into sleep mode. Then, once you have run the battery totally flat, charge it up while the macbook is off for a couple of hours to make sure the battery is 100% before you turn it on again.

You should see an improvement with this. If you do, but its still not in the high 90's then repeat the process.

CoconutBattery have been known to be incorrect at best (not saying it doesn't work for everyone).

Ok, so I tried what you told me, and nothing. Through coconut, it says that my battery has only 86% capacity than the original, and only 4515mAh, instead of the 5200 mAh. Now, is this normal??

mine is only a week old and after a calibration, it's down to 93 percent.

I think something might be wrong with mine.
