My 2016 MacBook Pro (space gray) was streaming a webinar (Webinato) I closed the cover but an hour later when I lifted the screen the laptop never came on again. Ever heard of this?
Any time you are near the mains you benefit from being plugged in, especially a streaming app., if you need the portability then battery obviously.
There is no harm being on the mains, your battery will have a longer life/cycle count.
If you are having an issue booting after it has been on the charger for a while,
Try resetting the SMC https://support.apple.com/en-us/HT201295
