Hi @marktaylor , presumably you do not have a lower level set in Battery Protection. Ensure there is no debris in charging port,are you able to try another charger just in case an issue there.
you could try clearing the USB cache:
You could also clear the USB cache: To do this, go to Applications and Activate "Show system applications" by tapping the 3 lines to the right of Your Apps, select ok.
Find the USB settings app and in storage, delete the cache and data. Restart the device and see if that makes a difference.
However it may be a Beta issue and if not resolved best to send an Error Report.
