Better than iOS 10? No, there’s still skitters here and there and the RAM optimization is not as good as it used to be on iOS 10.3.3

I’d say ios 12 latest beta is equal to or better than 10.3.3 and should be fully patched against meltdown, specter, various Bluetooth and WiFi vulnerabilities.
 
Ive updated to iOS 12 beta 5, from iOS 10.3.3. I was so scared, but it was a good decision, trust me. I didnt even used iOS 11 on my 6S, I just went straight from 10 to 12, so I know what im saying. Its the same as iOS 10, maybe even better with all the latest features and the perfomance is great!

As someone who is on 10.3.3 on an iPhone 7 Plus, I am very interested in this answer. In my mind, iOS 12 being superior to 11 was never in question. It had to be, iOS 11 IMO was an absolute abomination. The question in my mind has been, how is 12 in regards to 10.

I have the 7 Plus on iOS 12 and while its a major improvement over 11 I would still say iOS 10 was faster. There was a snappy feeling to the phone which is missing on iOS 12. Important point to note being that iOS 10 on the 7 Plus has the fastest home button. They slowed it down in 11 and it’s still slow on 12. You may find it jarring.

I think so. I still have an iPhone 7 on iOS 10.2.1

I also have an iPhone 7 running iOS 12 Gold Master

I have not compared the two haha - I could if anyone is interested in anecdotal thoughts

Please do! If you could compare overall smoothness, app animation, and the home button speed that would be fantastic.

I’d go to 12. It’s gonna get better. You can’t compar iOS 10.3.3 to iOS 12 beta. 10.3.3 should’ve had all the issues worked out.

You can compare. Some are comparing what they have now against what is available. There’s no option to go directly to 12.3.3.
 
ios 12 on my SE is awesome, as good an experience as i've had on any iphone. i think the real question should be: will ios 13 be 1 better than ios 12, and 3 better than ios 10...
 
I tend to criticize Apple more than compliment but I will have to say they did a fine job with iOS 12. My 6s seems like a new phone. Could be placebo after dealing with iOS 11 for a year but it seems just as snappy as the day I bought it almost three years ago.

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

I cannot thank you enough! Been hoping someone would write something up like this for ages now! Thanks! Judging from what you have written, is it safe to say I should go ahead and install iOS 12 when it's officially released?
