Is it worth it to combine many different sprites into one tile?

Question

Unity

Hello. There was a question regarding sprites and performance in U5. As I understand it, when using tiles, performance increases due to a decrease in queries to the graph. files (maybe I put it wrong, because I'm not strong yet in the GPU operation scheme). If so, is it possible to put all the sprites, for example, of the interface, and there will be quite a few of them, into one tile - will this increase performance, now almost everything is separate? Those. it's normal if you combine into tiles a lot of sprites not of the same type, but of the same group, for example, if the game ends up with 2 tiles at all: the interface and everything else? Thanks in advance.
PS Tentatively, it needs to be optimized for mobile devices, so the question is relevant for me.

in my opinion, juna collects your sprites into one single atlas when compiling, so don't sweat it.
