Greetings, rushdatmac.


Welcome to the Apple Support Communities! It appears that your iPhone XS Max isn't charging correctly as the percentage showing for the battery hasn't changed from 81%, and I'm happy to help.
First, I want to invite you to follow the steps in the following resource article:
If your iPhone, iPad, or iPod touch won't charge


How to back up your iPhone, iPad, and iPod touch -- Since restarting your iPhone didn't resolve the issue, please be sure to have a fresh backup to keep your personal information safe. In order to back up your Health data, the backup needs to be encrypted. iCloud does this automatically, but iTunes doesn't. If you'd like to use iTunes to back up your iPhone, refer to this article: About encrypted backups in iTunes


If you can't update or restore your iPhone, iPad, or iPod touch -- Even though the title of the article isn't specific to your issue, the section titled "Put your device in recovery mode and set it up again" will walk you through all the steps to reinstall the iOS software on your device. Test the issue once again.


Let me know how that goes, and take care!
