MBA13 battery indicator

[rayjay86]

I bought my MBA about a month ago. i5 256GB.

iStat Pro and Coconut show battery health at 98% and now when I charge it, it doesn't go over 96-97% charge even though it says "battery fully charged" and the green LED on the charging cable is on.

Is there a way to reset this?

I only ever go through full charge cycles (once in a while I'll plug it back in when it's between 40-70% charged. I did the whole calibration from 100-0% when I first bought it.

I hardly ever leave it plugged in for long periods of time. Basically once it reaches 100% I unplug although on occasion it does stay plugged in for a few hours.

Anyone know why it doesn't show 100% charge or why the battery health has dropped 2% in a month?

It's normal. There are a few threads on this issue already if you want the details.

It's normal that your battery health fluctuates up and down over time.
It's normal that your battery may not charge to 100% every time.
It's not necessary to unplug once a battery is charged, as it stops charging and cannot overcharge.

This should answer most, if not all, of your battery questions:
