Citation needed - but I suppose you could say the same about my claim.

I’d love to test this properly with an infrared thermometer but I don’t have one. All I have is an anecdote that I’ve been charging my OLED in it’s case since release and have never had an issue - not zipped up given the wire, just the lid flipped over on top.

I guess either way the BMS would prevent any real damage from occurring, which is why I say it’s a non-issue.
