Hi

My steam deck shoes 99% battery until it suddenly drops to 5% and warns me of low battery. I am still able to play for 15 minutes until it turns offs. When I plug it into the energy source it charges 1% every 2 seconds. Need less to say, this is bs.

I did try to discharge to 0 in the menu and in a game, but it did not fix itself.

Any idea how to fix this?
