The intentional slowdown was directly related to battery life. They got sued over it. But if you put in a new battery, performance returns to previous levels.

Apple even tells you in your battery info settings page whether you are running with “Peak Performance Capability”.

So generally I believe that Apple respects privacy more than google overall.

That doesn’t mean Apple is some privacy beacon.

But I have never had Apple randomly turn a setting on my phone on. Google got caught redhanded doing that. I had been using android for years until that incident.

Apple I buy my phone. Google I am the product.
