I originally posted this on the questions thread but thought this would be a wise idea to post here.
I put my Switch on my coffee table, off any charger, overnight. When I put it to sleep yesterday it was around 79% charge.
I woke up this morning to play on it, and it was at about 12%.
I have done multiple resets as advised by this community but they don't seem to work now, unless I'm doing it wrong.
Where do I go from here?
Also of note, no games were running during all of this.
