In that case, why don't Android devices face sudden shutdowns as frequent as iOS devices (yes, you can point to isolated cases, but it is nowhere as prevalent as Apple devices pre-throttling)? Note that this problem only occurred on devices where Apple fully designed the chips (iPhone 6 and later). "Off the shelf" chips, and those used for Android, simply have a lot more of a voltage window.
