My full charge capacity shows more then the design capacity

Hello guys. I just bought from a friend a Macbook Pro 15 2017 and i have some issues with my battery. It drains around 10% per night on sleep mode and the Full Charge Capacity shows more than the Design Capacity.

Cycle Count: 26

Do you know what it can be, or what should i do?


MacBook Pro 15", macOS 10.14

The stated value for Design Capacity is a "nominal" value. The published value is a target and individual batteries' actual values cluster around that target. Some are higher, some are lower. It is better considered an average of what new batteries actually produce in final acceptance testing.


What you see is normal. My 2012 MBP's battery showed about 102% of "nominal." The previous model I owned was about 99% of nominal at time of delivery.


You have one of the roughly 50 percent that come in over the target value. Enjoy it!
