Hey Everyone,
I use Windows 7 as my main OS on my Macbook. I was just wondering if anyone else has experienced their battery percentage after charging saying 100%. Then it does not charge, which is normal. But I notice that the charge goes down after a while, like it is left plugged in, but it goes from like 100% down slowly to like 97% and 95%.

Just wondering if anyone else has noticed this with their macbooks?

Thanks.

PS - I use Mac OS X during school hours for the battery life :p lol
 
I don't own one, but this is normal behaviour.

There is electronics inside the battery which will slowly drain the battery.

When the battery is fully charged, you don't want it to re-charge as soon as it reaches 99%. Instead, it waits until it's dis-charged to 93%. If you leave it hooked up to your AC Adapter, it will eventually re-charge once it drops to 93%.

This article explains that this is normal.

It looks like the newer Apple machines don't start charging until they hit 93%, but older Intel machines will charge up when they drain to 95%.
