Sure, if your phone only needs a fraction of a watt and you're okay with an unshielded neutron source pressed against your head.

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.

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.
