Battery slowly loses charge while plugged in

[tigress666]

Ok, just curious, does anyone else's MBP's battery slowly lose charge over time even though it's plugged in? I've got a 2010 MBP 13".

Mine only is ever at 100% right after I have used the battery and just recharged it. then it will slowly lose that charge over time until I unplug it, use the battery enough for it to actually charge the battery when I plug it in.

(Oh, and coconut battery has never said it ever had 100% full original battery capacity, best it ever said was 97%).

Download Istat and look at how many recharge cycles you have.
This should give you some insight to your problem.

Says just 10. I mean it is just a few months old.

The battery loses charge by itself, it's normal. The battery is only loaded when it falls below ~95%. High CPU and GPU load draws from the battery even when plugged in.

Yup mine does that too.

When its fully charged i will just leave it plugged in for atleast 2days then probably on the first day i can see the battery drops to 99% then later on will drop to 98% this is where i will unplug and start from the battery and when the battery drops to lets say 25% i will charge it and the cycle continues for me.
