These iPhone XS vs S9 vs OnePlus 6 benchmarks test A12 Bionic as the killer chipset

Apple's proprietary chipset architecture is tailor-made for its mobile operating system, so it has a real performance advantage before, say, off-the-shelf Snapdragons of this world, even when the production node was 10nm in Apple's previous A11 Bionic processor. 

With 30%-300% better scores than the best Androids, A12 Bionic is now the chipset to beat

In fact, Apple's processors are so powerful that the company deliberately throttled them significantly when an iPhone battery degraded below a certain threshold, so as to avoid random reboots by peak power requests, resulting in the #battterygate brouhaha. On the plus side, it brought on $29 battery replacements for older models, a perk that is now coming to an end.

On the whole, this is not a fair fight for Androids, as not only are we comparing 10nm vs 7nm processors, but also custom chipset architecture optimized for an in-house operating system, against a smorgasbord of chippery and interface overlays. 

Still, the best Android has to offer now does synthetics on par with last year's iPhones, while the new XS and XS Max blow them out of the water. The performance difference is largest in browser benchmarks, up to 300%, while in multi-core tests the A12 Bionic is just 30% ahead of the best Androids can muster, arguably on account of Apple's throttling shenanigans. 

This extra power should be most noticeable in gaming or browsing activities, but the everyday interface grind and app transitions would get a worthy boost, too.
