IN MY CASE nothing
Cannot disagree with you.

About swap on SD-card. Has somebody tested impact to battery (standby time, etc...) comparing swap on eMMC vs SD?

eMMC is 1.8v interface, but SD card signals needs to go thru levelshifter + filtering component, which increase load capacitance on this interface (IC 1.8v <-> 3.0v SD-card). In practice it means more (peak)current taken from battery (incl. 3v regulator) to drive card/levelshifter.

Also swap on SD-card require that interface must be active all the time.

Q: Is there real benefit to have swap on SD-card?
