I've been doing a bit of this as well. Unfortunately, it seems that Google hides the 'Cached' link on mobile devices (at least in Safari) unless you 'request' the desktop version of the search results page. I don't know why they do this; it's extremely obnoxious. But then again, this kind of obtuse nonsense is par for the course these days.
I simply prefix `cache:` to the URL and that brings up the cached page for me. Of course this will only work if your default search engine is Google.
Browser dev and minimalism go together
Another annoying example, Chrome on desktop shows you download speed, on android they don't.
