No, it only checks the battery state. I'm suspicious it runs off the battery even when plugged in, and works like power>charge controller>battery>power manageme

No, it only checks the battery state. I'm suspicious it runs off the battery even when plugged in, and works like power>charge controller>battery>power management>system rather than power>power management>system when plugged in(or "plugged in" to a case). An iphone usually wont boot with no battery
