Switch Lite draining battery fast (even when it is powered off)

[Gamefreak001]

I have a Switch Lite that drains battery fast. About 10% in 5-10mins. If I am at 95% battery and power it off completely overnight, the next morning it is at 10%. It’s not the battery as I have it disconnected and the charge remains at the same voltage reading with a multimeter. I replaced the m92 and the 17050 chip. Any other ideas? TIA!

Are these chips of the board itself, or are these hacking modchips?

Those are chips on the board.
