After you update, it feels choppy, but I think it feels speedier than 10.3. Animations are much more fluid. Something about iOS 11 feels "clean"er than 10.x
GM was choppy on my IPP 10.5 & 6S+ for about a day. After that and soft reset it was much better. Even had Calendars screen glitch on IPP that went away.

It is much speedier now, I think it was because right after you update, it takes time to sync all the data.
 
Updated my iPhone 6 about 7 hours ago and it's like there's been no change to its performance at all. No lagginess, no glitching, just the same old reliable performance as per always. I'm enjoying the UI changes and am extremely glad that HDR can be turned off on this phone, unlike the iPhone 8's and presumably the X also, as the inbuilt HDR of the iPhone creates too much ghosting upon blending the three exposures together.
 
I updated my 3 year old iPhone 6 to iOS 11 today. Update took a while (as usual) and the phone felt hot to touch for about 30 minutes after completing the update. I know that the OS is performing all sorts of updates and indexing in the background, so I wasn't concerned. During this time, the phone UI is laggy, but thats only to be expected. Once it had finished everything and seemed to be settled down, I gave all my favourite apps a run through and all of them are silky smooth, as is the whole UI. There are no issues at all that I can see.. It's like having a brand new phone :D

Overall, I am really impressed with the responsiveness of my 3 year old iPhone 6 and will probably hold onto this till next September.

iOS 11 installed on my 6S Plus.

At first it was janky. Updated the apps since I waited until the OS was installed. Gave it like an hour and everything was buttery smooth. I guess it was re-indexing or something.

It feels faster than 10.3.

Impressive.
 
The battery was never in question.

Funny, anytime I heard anything negative about the 6 plus it was always the battery.

I would ask what issues you feel plagued the iPhone 6 Plus but does it really matter lol.

New phones are here, and this 6 plus has served me better than well. It’s all I could ever ask out of a device.

As I type this on my 6 plus running iOS 11 like a champ.
 
I saw some YouTube video the other day and it said the location services and something else in ios11 resulted in it getting 1 hr less than in iOS 10.3

I really like ios11...but if true, I would think it thru before upgrading.

I'm on ios9 and staying with it on account of the jailbreak.

If you look at the generations of A-processors in all the recent iPhones, it bears out that the A8 CPU was not a very good one in comparison to the others in terms of computing power.

The a7 and a9 CPUs were much better.

All water under the bridge now of course. :)

I had the same experience, first 30 minutes or so I was worried, it was slow and jerky doing things, but today I think it runs better than iOS 10, I am pretty impressed with it tbh.
And to all the 6+ haters it's been a great phone for me over the last three years, it's the first phone I haven't wanted to upgrade after a year or two and could easily last me another year, though the lure of new shiny things is getting stronger, however the high prices is currently holding me back.

Installed IOS 11 GM on my 6+ last week as beta and after one day of quirks and stumbling, it’s running as smooth as it did on 10. I mean, yeah, it’s slow opening apps, refreshing pages, and doing tasks in general but not slower than it was on 10. I dig the changes in 11. I need a new phone though...I want to play with that ARKit and it’s only supported on the 6S series and up...
 
The 1GB RAM I think is what really slows it down. It was a concern when the phone was brand spankin new. I've decided to hold off on iOS 11 for now, though I am installing it on my iPad Air 2 so I can mess around with it a bit.
Curious how it is on the Air 2, I'm still on iOS 9 for fear of it slowing down.

This.

All iOS 11 did was make me not get the 8 or the X since my 6S Plus is still a beast.

Heck, it's single core performance still BESTS Samsungs S8. That's just crazy.
 
It's a real shame that a phone released in 2014, only 3 years ago...should show its age so quickly.

ip6 was a very weak phone...the A8 and 1gb RAM did buyers no favors. And the 6+ was an even worse travesty.

Exactly this. People tend to forget it’s a combination of factors, not just one single cause.

The A8 should never have been in the 6. It was a very modest improvement over the A7 yet it had to push much more pixels. The 6 Plus even uses some weird scaling technique that puts even more strain on an already weak GPU. That coupled with a lack of ram caused this phone to age so quickly.

I am running iOS 11 now on my 6 Plus and it’s an abysmal experience - at least compared to my wife’s iPhone 5 that runs iOS 10 absolutely flawlessly. The UI is so laggy and sluggish and everything takes ages to load. Even my old iPhone 4s ran its final iOS (9 I believe) much smoother than this. Yes it was slow, but it didn’t lag or stutter as much as my 6 Plus does right now.

I hope the 8 I’m upgrading to will do much better in its third year.

Sometimes there's a slight hitch in the animations when closing out of an app but general operability seems unchanged so far.

Installed iOS 11 last night on my 6+ and it runs just fine. No discernable lag compared to iOS 10.

A7 & A9 chips are powerful and power efficient, a trend that Apple is continuing with A11.

A8 is that stepchild that is 40% better than the OG 64-bit A7 but is not better enough to warrant any more attention.

TBH, that 40% performance gain is negated by increasing those screen size anyway.
 
I played with it more and more last night, I've had some annoying lag issues. The most notable was opening up camera. Switching from photo to video, I'll have a frozen screen for a good 5, 6 seconds and then I'll finally see something to start recording. Switching to time lapse, the screen simply froze and did nothing. I had to double click home button, swipe away other open apps...including camera and start over. Opened camera and it was fine. Sometimes it runs smooth..then it becomes a little buggy.
 
This is what really bothers me about Apple. They bug you to upgrade to the latest iOS so that they can brag that 87% of devices are on the current iOS at their keynote address. But in some cases, it is absolutely a bad decision. You would think yOu could trust Apple in updating its own device. It's pretty devious I think.

The 6 Plus was the only iPhone that Apple ever released that was laggy and slow (by iPhone standards) right out of the box. You should've upgraded at least to a 6s Plus a while ago.

Same for me with the camera on the 6 Plus, except I already had those issues in iOS 10. Sometimes it’s even confused by the orientation and the UI moves around a bit before it settles. I often make photos that aren’t oriented properly (although that could also just be a failing accelerometer and not a performance issue).
