I was having the lagging issues on my iPhone 6S also. It would lag to open messages and settings. I rebooted the phone a few times now it's fine.
For now, it will return, it did in my case. I have rebooted about 3 times since I've got the phone this morning and it has always returned
 
I'll be setting mine up tonight, but I hope this is just due to temporary background indexing and such.

This is what I was thinking. I haven't updated to 9.0.1 yet and now I might hold off until the phone has had some time to get all its background processes done.
 
That's just how iOS 9 is. People didn't notice it at first (blinded by the newness) but I noticed it earlier. If I was going to update, I'd do it .. man, I don't know, probably iOS 9.5.
 
this will not help. do it and you will be disappointed. unless you had a corrupted backup it's basically the same thing. not sure why everyone always says this.

now from a cleaning standpoint setting up as new makes all the sense. you only end up adding back the apps you use

It actually works.
 
Nothing Apple has released in the last year is "ready".

That's the pressure of a yearly release cycle, though.
I know, it takes them 2-3 months after a major iOS release to get the major bugs and lagginess fixed. I'm still on 8.4 on my iPhone 6+ and plan to stay on 8 for awhile since 9 seems so buggy for folks right now. I remember when I first got my 6+ I was rebooting my phone multiple times a day for the first month or so because apps would freeze or crash or the whole thing would just lag like crazy. It's not the hardware as much as the buggy software ... especially on a X.0 release and I do know that 9.0.1 is out but it will take several releases for the bugs to really get fixed. It seems like every year the earlier adopters are beta testers. I can't believe some of the bugs that get released, either apple has horrible testing or just doesn't care about these bugs and is more worried about making their deadlines.

I noticed this almost immediately on my 6S. Updated to 9.0.1 and the issue was still prevalent. I enrolled the phone in the beta program and am currently running 9.1 beta 2 and while the issue has been reduced, it's still there. All of this from a device set up as new.

I'm hoping after the phone has had a day to index it will go away fully. Either way, 9.1 beta is more stable than 9.0.1.
 
Same issue. Set up as a new phone.

Buttery smooth then occasional lock ups. Never had this on the 5S in 9.0.1

Why would they optimise iOS9 for older devices? It doesn't make any sense and it's worrying because I spent 9.5 months waiting for Apple to fix the occasional stutter and freezing on my 6+ before I realised they were never going to.
 
The 6+ had the lag and freeze thing going on...


I've restored a few times and set up as new twice on my 6plus and have all kinds of issues that I hope apple fixes fast. I've never had these types of issues with any of
My iPhone's on any of the iOS updates. Very frustrated.
 
So there is no setting or anything that will fix this and is prevalent on both S models.

Only way it doesnt bother me is unlock the phone then wait 5 seconds then start using it. Then the problem goes away. I guess we were all using our phones wrong. -:)
 
I doubt this is going to get fixed anytime soon! My original plus was not nearly this bad before 9.0
 
People with the freeze after unlock/touch ID, disable the live wallpaper (if you are using that). It fixed the issue for me.

I think it's related to 3D Touch.
 
Ok I think i figured it out if you turn off siri or spotlight search it will fix it. Did it on and off straight cause and effect
 
Buttery smooth but I did a setup as new phone even though I had a ton of stuff on my 6.

Doubted. I don't have live wallpapers on and the freeze & lag is just absolutely insane coming from a very good 6 plus that ran awesome before 9.0

I also think it may be hardware based also. Does anyone know if this problem exists at all on the 6s?

I restored mine from backup and updated to 6.01 and it works fine. I haven't noticed any oddities yet. I guess some people are having problems and others not.
 
More likely it has to do with iOS 9 than anything else.

A user in the JB forums just went back to using his iPhone 6 because his new 6s is in an unbootable state after restoring iOS 9.

Apple replaced my iPhone 6+ last Sunday for the price of a screen repair because restoring to iOS 9 caused a bootloop. The Apple genius told me that Apple is having a lot of issues with iOS 9 and restores right now.

I don't think iOS 9 was really ready yet.
Maybe I am misunderstanding. They acknowledged an issue and required you to pay to replace? Or was the screen already fracked?
 
Did a restore. Working like butter for me.

Unlocking the phone, scrolling down data-heavy websites with a ton of photos? How about rotating from portrait to landscape? Oh and does the multitasking tray stick in portrait still and not switch to landscape when you rotate the phone?

Please re read. I have the 6S. I'm comparing.
