Rapid battery drain

hi

I’ve changed the battery, bq chip, mt chip and tegra chip but the battery is still draining rapidly. Anyone know what else could cause this ?

Thanks

Check temps of dcdc converters with a normal mainboard and look out what gets hotter than usual, then replace that part

Thanks tried that. Heat is the same on both boards . No excess heat. Strange one this.

Hi,

Maybe this will sounds dumb but, is the Nintendo switch draining equal if the joy cons are connected to the switch or not?

Just want to make sure its not related to the Joy cons.

Same either way. Really at a loss with this one.

How much higher is the current draw compared to a normal board?
