    I just bought a new rMB mid-2017 and noticed that my battery health only seems to be 84% ?? The System Information app says "Full Charge Capacity (mAh): 5525" but "Charge Remaining (mAh): 4869". This is with 100% charged and plugged in.

    Should I take it back and swap it for a new one? I've Googled online and found several people with this problem on different macs, but no answers as far as I can find.

    Edit: now at 5169 mAh remaining after a reset... maybe I should just let it run down again and reset again and let it recalibrate properly.

    Give it a few battery cycles and see if it settles in at a decent number.....
    You have 14-days to return it, use it if needed.

    Mine came in at 101% on first charge.
