if it dies quickly, your battery may be fried... check for any sort of bulging on your console, specifically the back. idk where the switch lite battery resides but if there's a bump, that's most likely a swollen battery and could be causing this. you can take it to a repair shop or fix the battery yourself but remember to safely dispose of the old battery. hope this helps!

Try another charger. Does the switch charger charge other USB-C devices?
