Thanks for your reply. I left the MacBook charging for about 13 hours today without using it. I unplugged it and 20 minutes later it just shuts off in the middle of me using it. Battery was at 99%. I don’t understand why it is doing this.

A relatively new experience these batteries coming out of the factory with "unknown full point" —

ex. here a different Mac, different issue, however the charging protocol is recommended as a way of getting past this issue:

If your MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports) keeps shutting down

have a look see and report back any resolve.

Do these two and let's see if it solves the issue.

The batteries on the newest MacBook Pro are coming through with their "full point" unknown.

Correcting this requires that they be charged continuously for eight hours or more, preferably while doing nothing or off.

MacBook Pro will Never overcharge.

Connect it to power whenever power is available, and use it on battery only when power is not available.
