Please do! If you could compare overall smoothness, app animation, and the home button speed that would be fantastic.
Sure thing!
Ok, so I am comparing two iPhone 7's
A few caveats:
- One is running iOS 12 GM (which should be the same version that is released on the 17th), the other is running iOS 10.2.1
- Neither device is jailbroken or running unauthorized apps.
- One iPhone 7 is a matte black, 32GB device, the other iPhone 7 is a jet black 128GB device
- I did not test low power mode
(PS - that iOS 10 control centre is nice and simple eh?)
So I tested all sorts of apps - stock apps such as Phone, Mail, Safari, Messages, Notes, Calendar, Weather, Camera, clock, app store
I also tested out third party apps such as Google Calendar, Youtube, Google, NHL, EPL, Hue, OneNote, Outlook
And I also tested general UI stuff like app switcher, via both 3D touch and home button [note: 3 home button click shortcuts was turned off for speed], accessing widgets, scrolling, accessing control centre and notification centre
iOS 10 and iOS 12 are *very* similar in performance. A few things load a bit quicker on iOS 10 (and by a bit, I mean less than a second), such as app store and safari webpages (surprisingly, some webpages loaded quicker on iOS 10 than 12 which one would think would not be the case due to increased efficiencies in safari script with later OS updates)...but I must stress it was marginal
typing texts and keyboards popping up, all stock apps, everything else was unremarkable....everything loaded more or less the same (identical speed)
Same with UI, but iOS 12 has faster UI animations which is noticeable when going in and out of folders or tapping the home screen (and singing in with touch ID as well a tiny wee bit quicker due to animations)... CC on iOS 10 is a bit quicker to launch though
I do like iOS 10's 3D app switcher animations more though, it was the one area that felt a bit quicker animation wise, but both 3D touch gestures launch the app switcher at the same time...home button animations (going home, or one click) is faster on iOS 12 due to the quicker animations
Third party apps, the ones I tested, launched the same too
They were very similar in performance, almost identical.
For fun, I also compared iOS 12 on the iPhone 6s to the 7 -> 99% identical in speed
And I also compared iOS 12 on the iPhone 6 to the 6s -> seemingly
everything on the 6s was about twice as quick to open or work or launch, same with 6 vs 7
That said, iOS 12 runs great on the iPhone 6
