Was accidentally breathing in fumes from a phone battery while sleeping
Long story short, I have a Samsung Galaxy Note20 Ultra on my desk that I haven't been using for about 3 weeks ever since I got my new phone. I was napping today for about 40 minutes until I woke up to an odd chemical smokey smell. After a minute I realized that it was my old phone and immediately put it outside and started ventilating the room. There wasn't any visible smoke and the phone wasn't on fire or anything, although was hot to the touch. I'm going to assume though that I was breathing in that battery smoke or whatever for possibly 20 minutes or more. Is there a chance that I could get sick or it caused harm to me? I feel fine I think, other than the anxiety of knowing I was breathing it in for who knows how long, not sure where to go from here.
