hey guys, I run cocunut battery and battery health apps on macbook retina but my battery current charge is below my battery maximum charge even if I leave it charging the whole night. So my readings on a full charge are..

Battery charge
Current charge 8114 mAh ( 94 % )

Battery health
Current max: 8551
Original max: 8460
( 101.3 % )

So my battery current charge isn't at 100 % even at a full charge

Apple's laptops don't charge to 100% then run off the power. They charge to 100% then discharge the battery to between 92-99%. Then the power kicks in again and charges it back up.

My advice: don't worry about it until this becomes a problem. Don't feel the need to become pedantic or obsessed about something if nothing is wrong.

It basically means your battery has lost the ability to hold a maximum charge. Another way of saying it is that your battery is at 94% health.

let your battery drop below 94%, then plug it in. it will charge to 100%, this normal, charging does not take place until less than 94%.

Iggibar, you're reading it wrong. Current charge is 94%. Battery health is at 101%, or better than expected.
