2019 16" MacBook Pro - low battery health out of the box

I have a 2019 16" MBP that I just received today, and it only has 1 battery cycle. However, I have Battery Health on all of my Macs, and despite the device being essentially brand new (manufactured 11/20/2019, CTO on 11/30), the battery is already at 8196 mAh out of a possible 8790 mAh - already a 7% degradation in two weeks. I can't possibly imagine that this is normal operation for the Mac. Even my 2011 17" MacBook Pro is at 91% battery health after 8 years of operation, and more than 200 battery cycles...

Does anyone else have similar issues with their 2019 16" MBP?

It has something to do with the way Apple is shipping these new batteries in the new machines.

The go to way is let the battery charge past full by several hours—say over night for best results—then in the morning reset the SMC.

After a few days it may correct itself, you can also reset SMC to see if it helps.

If after a few days and/or resetting SMC there is no improvement you should visit a Apple store.

Be sure you have charged your new MacBook Pro completely. This requires it to be connected to the power adapter for Many Hours beyond the point where it says 100 percent charged. Best results are obtained from leaving it connected overnight while powered off. It will NEVER over-charge.

In the morning, use the procedures in this article to reset the System Management controller. Be sure to use the keys in the EXACT locations specified -- the keys on the other side of the keyboard with the same labels are not "wired in" and will not do the job:

Thanks so much everyone for the replies. I haven’t had a new MBP since 2017 and wasn’t used to how it worked yet. I left it on charge for a few hours and now it’s looking above 100%.
