Aren’t most of the power efficiency gains from integration and miniaturization? If you’re charging/discharging a larger amount per bit, it’s going to take more power than a smaller (physically and electrically) equivalent would. That tends to work against practical field repairs (other than replacing at the IC or subassembly level).

The shorter the distance between two components the less energy you're going to lose to resistance, electromechanical components have physical friction, conversion inefficiencies going from electrical to mechanical energy, and the energy needed to accelerate a mass.

Really, what nukes the repairability of a lot of products these days (ignoring the repair-hostile practices of many companies) is the cost of the item vs the time needed to disassemble the unit, track down where something went wrong, repair it, reassemble, and hope that component didn't blow because something else upstream is faulty that you didn't find. Cuba and Africa the time is cheap while replacement units are somewhere between expensive and unobtainium, USA/Japan/Europe not so much.
