iPhone iOS 9 destroyed my iPhone 5s

I'm quite frustrated by the performance of iOS 9 on the iPhone 5s. There's stutter all around the place and framerates are generally really low. Scrolling in settings or Twitter feels very jerky. Opening control center and spotlight is superlaggy.

Weird thing is though, the iPhone 5 seems to actually perform better than the 5s. I carry them both and the difference is really huge, animations on the iPhone 5 are supersmooth, smoother than the 5s! Truly odd.

I don't know the specifics, but I think it has something to do with metal that does not seem to perform on 64-bit chips as it does on 32-bit chips.

However, I think it's unacceptable to release an OS update that slows down your phone this much. My 5s has gone from super "why would I want a new phone" smooth (8.4.1) to super "this phone feels very old" laggy. Just unacceptable and I'm really disappointed. :(

My iPhone 5S was initially laggy and then I put it into recovery mode and restored it via iTunes and restored from the back up and it was fine.

Metal doesn't run on 32-bit chips, only A7 and newer. I would recommend doing a full restore. OTA updates tend to cause problems (at least for me) - I always do a fresh restore when a new release comes out, with the exception of an x.x.1/2 release.

Full restore / OTA update thing is all placebo. I set up a 5S through iTunes restore and it's laggy.

ios 8.4.1 is still being signed. If the full restore doesn't help, I'd suggest downgrading before they stop signing it.

No way I will do a full restore. Never done it, never will.

There are some bugs that everyone has, and then there are some issues that not everyone has and sometimes can be cured by reinstalling (as has been the case with computers for quite some time).

5s here as well.

I was blown away at how much faster 8.4.1 was compared to 9.0 when I updated.

Definetly sticking to this version for a while until Apple brings back that buttery smooth performance we all love from iOS 8.4.1 to iOS 9.

It reminds me of iOS 7 on my iPhone 4S.

I hate the idea that I can physically outperform my iPhone.

Using the phone app for example. I can end a phone call, goto recent calls, press a name and call the wrong person. The problem is the app refreshed from the previous phone call and the list shifted.

Also I can answer the phone now and it vibrates against my ear because although I swiped it, it hasn't actually picked up yet. With bluetooth it rings twice before it shows me who is calling. If I answer before it shows me I can have already said Hello before it does show me.

Things like that are what annoy me. I don't really care too much about the fluidity of the animation.

However what REALLY annoys me is because of my position at work I have to hear 25 guys complain like children about how slow their phones are now (mostly 5C's and 5S's) and how they want new phones. I'm about at wits end and have had to excuse myself once already to prevent myself from blowing up on someone that doesn't even need a phone at all for their position.

I did a Restore on iTunes and set up as a new phone and it DEFINITELY works. There was no damn placebo. I have a 6+ and did an OTA upgrade and it made it practically unusable. The answer is a restore. I not know if you have to go as far as I did and set up new phone, but it sure made my phone feel like new.

Shows how much you actually know about how delta OTA updates work. Ridiculous. If you didn't know Metal doesnt run on 32 bit chips, I'm not surprised at your assumption of restores, either.

Turn off wifi assist. Turn of spotlight search and Siri suggestion and finally turn on Reduce Transparency in Accessibility and I think you will find it much much better.

Yeah except not everyone is having the issues you are. No two iPhones are exactly the same because of variables in apps, user data, etc. You have nothing to lose if you try a restore.

This is true, but I did restore / Set Up As New (with stock settings) on my iPhone 6 testing 8.4.1 / 9.0 GM / 9.0 Public Release / 9.1 Beta 1.

8.4.1 was the clear winner, with all of the 9.x's showing slight lag throughout the OS. This was a controlled experiment without variables and proves, at least to myself, that you will see slower performance with iOS 9 on an iPhone 6.
