It's a common sense to me, but if you want, we can do the math. Should be pretty easy to calculate humidity and rice desiccant properties to end this joke once and for all. Logically, it should be better to let phone dry in open even, instead of creating closed space in the bag of rice.

You can watch the video muted btw. PCB condition shows clearly the level of corrosion from just a little bit of moisture.
