If the mars rovers can function on a fraction of a watt,

It doesn’t?

Perseverance's power system works essentially like a nuclear battery. …The power system will reliably produce about 110 watts …The MMRTG also charges two lithium-ion batteries, ... Perseverance's power demand can reach 900 watts during science activities.

Yeah, see!

An RTG could power my phone!

Sigh, let me spell my point out for you...

What I mean is that I can absolutely believe that a solid state battery could power the next gen smart watch, I doubt it will.

Just as an RTG could power my phone, but I doubt that it will be powered by it.

Uh yeah that definitely needed to be “spelled out” from your prior comment.

To give some perspective on this, I've lived for the last three months in a camper with a DC fridge. 1350 watt battery. The rtg at 110w/hr would keep my battery charged. 50 watt tv, 72 watt fridge, 24 watt starlink plus lights and waterpump. It would be just enough for me to live on I'd say.
