Those are the collisions... Not sure if it's too high, I don't have a reference.
Is this before or after you made those changed to the events?
~200 collisions per tick is perfectly fine. Even 1000-2000 per tick should not be causing major lags on mobile. So if the game still runs poorly on mobile, then the issue is with something else.
Make sure that Framerate Mode is set to "V-synced" in project properties.
