Last night I was playing VRchat with a friendly group of guys, we were playing cards against humanity, after an hour went by or so all of the guys started plugging their headsets in to continue playing. I didn't plug my headset in right away because I still had 50% battery left.
So about a half an hour later I decided to plug my headset in, and that's when I noticed, my headset continued to lose charge.
I asked the other guys how their batteries were, they said once they plugged it in their percentage continued to rise - while mine continued to fall.
I also could not add friends, I could send and receive requests, but even if I accepted them, they didnt appear on my friends list - that being said, once my Quest died, I lost my new friends, too.
TLDR; My Quest wont charge while I'm in game, the charging light is on but my battery keeps draining. YES, the charging works when my Quest is off, but it doesnt work when it's on.
