as i understand from specs in charge or boost mode for sustaining those functions, some activity on i2c bus is needed.
if NO CHARGE mode why i2c read / writes activity ?. this useless activity drain the precious battery.
i will look closer on specs for a decent reason.

if vbus sensing for mode selection pop-up is needed instead of pulling status of BQ24k vbus sensing from 4030 via interrupt is preferred.

popup usb mode selection is not in bme or mce . what code is doing this selection ?
