not quite, the glass of water itself acts as a radiator since it has a significantly larger surface area than the phone, and water evaporation cools it down ever so slightly
even at equilibrium it’ll probably keep the phone a degree or two colder, i’d wager.

Evaporation will help radiate heat away, but the surface area to volume ratio is much lower than the phone by itself.
surface area to volume is only relevant for things that are generating heat throughout
