Was trading pokemon to my main switch when it suddenly showed a low battery symbol in the middle of the screen and turned off. The battery was draining normally and it wasnt too fast or too slow but as soon as it hit about half way, my switch just keeps going to sleep in CFW and then just completely turns off in stock. The issue comepletely goes away when charging and then shortly returns when unplugged. Is my battery going out or is this something else? My battery info is below
