I've been running a blocker to block GA and other junk on my PC, but I imagine I'm in a statistically insignificant minority. And I still can't block them on my iPhone unless I disable JavaScript entirely (though I'm running iOS 9, I'm not able to install a blocker for some reason; I guess Apple arbitrarily doesn't support them on my older iPhone model).
Ah, is that the differentiator? I see. Still strikes me as somewhat arbitrary, though - is content blocking such a strenuous task that it requires a 64-bit CPU? Wouldn't using a blocker cause the CPU to do less work in most cases since it doesn't have to download so many ad media files or execute as much JavaScript?
Yeah, I guess it's just time to get a friggin' new phone already, but this one ain't broke yet, ya know?
If anyone is looking for a good blocker for stuff like this, I recommend ghostery. I set it to block everything by default, and whitelist the few things I want. It doesn't block scripts served by the site you are on, so it doesn't totally break your browsing experience, like others do.
If your device is jailbroken (not sure if there's a jailbreak for iOS 9), you could add entries for GA to its hosts file. I use these on my desktop PC:
