The new iPhone 16 Pros are still stuck at 60hz on Safari. You can test it here: beta.testufo.com It would be nice if this was not only fixed for the iPhone 16 Pros, but also for future devices with above 60hz screens as well. When the M4 iPad Pro came out, it also was limited to 60hz until it was fixed. This would prevent this from happening for the 3rd time. 2062330 1 webkit-bug-importer 2024-09-23 07:29:29 -0700 <rdar://problem/136498574> 2062332 2 graouts 2024-09-23 07:49:35 -0700 I checked an iPhone 14 Pro running iOS 18 GM and it behaved as expected with regards to the "Prefer Page Rendering Updates near 60fps" where it would hit 120fps with that setting off, and 60fps with it on (the default). 2062334 3 possum.bracing0v 2024-09-23 07:59:29 -0700 Well I am sorry, I just realized I forgot to turn off the feature flag as the feature flags do not save on a devices transfer. I turned off the feature flag and 120hz now works on my 16 Pro max.
