smaller sensor pixel size = more noise?

Can we formulate a rule of thumb regarding relationship between sensor pixel size to level of noise?

with regular photo with all else equals bigger pixel size on sensor will deliver more light and less noise correct?

So phone vs APS-C is always going to lose with low light.

P.S. I am not touching on any smart solutions to conquer this problem the software way because they really don't work at night and if we talking about taking photos with exposures more than 1 second.
