    I'm having battery drainage during sleep issues.

    Green Joy-Con D-Pad Shells for Nintendo Switch


    It drains from full charge to almost 0% within 16 hours during sleep mode. Tried a factory reset, and also already tried swapping the battery with another Switch that works fine, so I'm guessing it's a chip issue. A Google search showed me someone had a Switch that keeps the fan on during sleep, so I checked mine and my fan is sleeping soundly as it should. I'm suspecting one of the IC chips may be draining the battery. Is there a usual suspect I should take note of before attempting anything?

    I might just give some basic Hardware advice. I am not crazy good with a software portion of it.

    It might not be an actual chips, it can be a ground caps or even coil(this one known for going bad on drop).
    Firstly i would open a console and checked may be some dust got in and made a drain.
    Next would be a test with a freeze spray or alcohol if any elements heating up in power circuit mainly near BQ chip.
    Make sure you didn't have dust or stuff in JoyCons rails something might just stuck there.
    Unpair JoyCons and check how it will behave without them directly or wirelessly connected to the switch.
