As soon as I upgraded my 6s to 11, I saw performance seriously degrade. It takes -seconds- to bring up the iMessage editor. My immediate thought was that Apple had liberally sprinkled wait() into the iOS 11 code base so that I'd feel like my ole A9 CPU just wasn't cutting it any more and I'd realize, as they do, it's time to upgrade. Or... maybe they are running every key stroke through the new Azure-enabled Cray computers to better predict what I am going to type so that overall, my typing is more efficient and I'm actually spending less time typing... Yeah. Yeah, that's it!

  The giant is pulling apart at the seams. It would take an obsessive, aggressive, near manic product personality to stay on top of something that large and keep it running at an extremely high level of quality. Tim Cook isn't that leader (which pretty much everybody understood on day one). Apple is seeing very serious problems across numerous aspects of their business, from product decisions to supply chain.

    This is revisionist drivel. Every year it's always "Apple is dying" as they continue to siphon money from every industry they touch. They are about to push a tonne of users into a higher price point with the iPhone X. The Apple Watch is an unquestionable success. We are on the precipice of seeing an ARM based MacBook based on their incredible work with A-series chips. They are also strategically very well placed with their Health and AR initiatives. Anyway look forward to your position in a few weeks when iOS 11.1 is released given the betas are looking pretty good.

iOS releases typically get a nice performance boost on the x.1 release. I wish it wasn’t that way (I’d like better optimization at launch), but this has been true since at least iOS 4. Edit: to respond to another comment elsewhere in this thread, Apple also tests on all of the supported hardware when prepping iOS.

My iPhone 7 - the latest iPhone at the time iOS 11 came out, and with the fastest single threaded mobile CPU for some time - can no longer play locally downloaded audio and be used at the same time without stuttering constantly. Everything is broken on iOS 11. Extremely frustrating. I will buy a new phone, but not an iPhone.
- sosborn 9y ago

  - zimpenfish 9y ago
    On the other anecdotal hand, I have an iPhone 7 and do experience this - normally through Overcast but sometimes Music will stutter and jank. HOWEVER I am running the developer preview betas which are notorious for being UX janky and logging insane amounts of crap on every action the OS takes. Which probably explains it for me at least.
- ballenf 9y ago
  I'm on the 6, two years older than that, and experience lag but never a single stutter on anything audio related. It sounds like an issue that a reset or reinstall may fix. I'd be similarly pissed off like you if even my much older phone did that.
kalleboo 9y ago
The worst thing for me is the Camera. If I want to take a photo of something that's just happening I don't even bother anymore since I can expect it to take 10 seconds to wake the phone, get into the camera, and have the shutter button respond and have it actually take a photo (sometimes it looks like it took a photo but it actually didn't save!).
- balls187 9y ago
  Interesting. Bored before bed so ran a quick test using my iphone7 and Ios 11.x, Google's stopwatch. The time from wake to photo was ~2seconds (using the lockscreen short cut). The time from wake to home screen photo app to photo was ~5 seconds. * I had to start the timer myself then go back to using the phone so I believe I could cut ~500ms. Since I have Live Photo enabled, the 2-second shots actually have a few frames that are sub 2 seconds. Going to the homescreen was accidental. In each attempt, I attempted to use the lock-screen camera shortcut. As a whole, the experience using the iphone is too unpredictable to be reliable for quick reaction shots (< 3 seconds). A number of times I either: bypassed the lock screen, didnt get passed the lock screen, unlocked my phone to a different app, and on one occasion, the camera app paused for a few seconds before focusing.
  - vostrocity 9y ago
    I really miss Samsung's 'double-click home button to use camera' on the Galaxy S6 and S7. Probably the most convenient implementation of a camera shortcut I've seen.

hedora 9y ago
It takes 14 sec to open maps and load a screen of tiles, 4 sec to open messenger on a my 6 plus. I’d love to see timings for this on the newer models. Also, I swear the rear-facing camera has lower color saturation and higher sensoe noise after the upgrade. I’d love to see A-B camera tests for iOS 10 and 11 on old hardware.

  Opening iMessage on a 6s Plus running iOS 11.0.3: Two seconds
  - lloeki 9y ago
    This kind of thread generally piles up on rants of frustrated users, so here's another data (counter-)point: both are <1s for sure, possibly even less than 0.5s on my 6S w/ iOS 11, from a cold start. Everything is snappy and responsive, enough that I'd have to film this on slow mo and time it to be sure of any delay metric. Overall iOS 11 has been a solid performer for me ever since the second public beta.
    - submeta 9y ago
      I wasn't complaining at all. I love iOS 11. Just wanted to give some input.
      - lloeki 9y ago
        Sorry for the misunderstanding, this wasn't aimed at you at all, I just responded to yours because you mentioned timings on a same gen device as mine and it seems mine is significantly faster. As for the rest, it's just that the sarcastic, conspiracist, passive-aggressive tone of many of the sibling comments is unnerving.
        napsterbr 9y ago
        What exactly my tone should be? I bought a very expensive phone that was unable to launch apps (50% of the time, when it did, it took several seconds) and unable to make calls (the receiving end would be mute and would not hear what I was saying). The phone was bought on an official apple store and had one day of use. Problems persisted for over a week. Tried all the possible solutions. The only one that worked was downgrading to 10.
kayoone 9y ago
This. My 6 Plus is barely usable now, to the point where it is annoying the hell out of me. On iOS 10 i was fine with the 6 Plus and thought i could easily use it another year, but right now it's barely usable. I compared loading a banking app on my 6 and my colleagues 7 (closed it before) and the difference is astounding (2-3 seconds slower). Also everything is just laggy including typing and taking photos.
- ballenf 9y ago
  I have the 6 and benefited from uninstalling 3rd party keyboards and doing a settings reset. Might have also done a fresh install. For a 3 year old phone, it's frustrating but still miles ahead of the last Android phone I kept for 18 months. It's still frustrating that the iOS update is basically forced on us instead of being an optional upgrade like on desktop. (Of course it's technically optionally, but the constant nag annoyance makes it effectively forced, imo.)
- pault 9y ago
  Odd, I have a 6s Plus and I haven't had any issues after upgrading. Sounds like it's hit and miss. I wonder if they changed the hardware during the production lifetime.
  - kayoone 9y ago
    6S has the A9 processor, the 6 has the A8, maybe that makes enough of a difference for it to not be that bad. I will also try the complete reset though.

> My immediate thought was that Apple had liberally sprinkled wait() into the iOS 11 code base so that I'd feel like my ole A9 CPU just wasn't cutting it any more and I'd realize, as they do, it's time to upgrade. That was actually recently debunked by Futuremark https://www.futuremark.com/pressreleases/is-it-true-that-iphones-get-slower-over-time https://www.futuremark.com/pressreleases/is-it-true-that-iph.... Important excerpts found at the bottom of the page: > Our benchmarking data shows that, rather than intentionally degrading the performance of older models, Apple actually does a good job of supporting its older devices with regular updates that maintain a consistent level of performance across iOS versions. and > That said, there are some factors that might affect people's perception of performance after updating an older device with a newer version of iOS. An update might add new features that use more resources or require more processing power. New apps developed for the latest models might not run as smoothly on older devices. Conversely, apps designed for an earlier version of iOS might not take full advantage of optimizations in the latest version. And then there is always the psychological effect of knowing that there is a new and improved model available, which can make your own device seem outdated.

  What is debunked? That the CPU has not changed during the upgrade? No shit sherlock. Synthetic benchmarks tell nothing of the end-user experience. Does Apple sprinkle wait()? No. Does the system become more and more complex and Apple taking less time to optimize because it runs “fine” on the [latest - 1] hardware? Yes.
  - zimpenfish 9y ago
    Technically the 6s is now [latest - 2] hardware. X/8/8+ have the A11 Bionic; 7/7+ have the A10 Fusion; 6s has the A9.

More annoying than performance is the ever increasing nagging for apple paid services, apple pay, apple icloud, etc. The platform is literally becoming a junk adware platform. It feels like an infected PC that pop ups ads randomly.
- Naomarik 9y ago
  This is precisely why I will not buy an iPhone again. Every single time I open my photos to show someone something I have to wait through two popups that are extremely slow to close. Also now I'm getting nagged to upgrade to ios 11 whenever I just want to use the phone. Abysmal.
  - nvarsj 9y ago
    What's the alternative? Android, especially Samsung infested bloatware, is substantially worse. The touchwiz upgrade prompts are WAY more annoying than ios ones. Plus the constant Samsung login junk. And then there is the heavy google integration that requires a google account for almost everything.
    - Naomarik 9y ago
      Except it isn't worse. Not anymore anyway. Any and all notifications just go up top and don't prevent you from using the phone -- even if someone calls you. My 3 year old Sony Xperia Z1C that I only use to for testing lets me jump into whatever app I want as soon as it starts immediately even though I can see there's like 50 notifications to go through. But I can do that when it's convenient for me. My main problem is that if I simply want to do something on any iOS now as soon as I unlock it I'm blocked by pop ups for things like making a back up and buying more iCloud storage and upgrading to iOS 11 -- things I never intend to do. There's no way to switch these off either. And they happen constantly, multiple times a day. Last time I used my iPad I dismissed a popup, opened up an app and the same pop up came a few minutes later completely interrupting me. I have no tolerance for these annoyances. Samsung phones were complete trash back in the day with their bloated interface but I've since switched to a Note 8 and the experience has been very good. UI is very clean and the performance/features on the phone are outstanding.
dvfjsdhgfv 9y ago
Unfortunately, this is a sad but regular scenario now. It doesn't matter whether Apple does it on purpose or simply doesn't care, but new versions of iOS degrade the performance of older devices (an in this case "older" doesn't necessarily mean "very old"). Some people simply choose not to upgrade, but this may have security implications - and in any case sooner or later you'll come across an app you need that doesn't work on an older version of iOS. You will upgrade, the performace will be degraded, and your previously "good enough" device will suddenly feel sluggish and old.
- Spare_account 9y ago
  Is there any definitive evidence for this? Has anyone benchmarked devices before and after upgrades to prove it? Edit: I don't mean CPU benchmarking which has been discussed elsewhere in this thread. More like usability testing, sequences of actions not invoking new OS features where possible, and also a second set of tests using new OS features because that's what most people's experience would be.
  - orloffm 9y ago
    It's difficult to achieve because one cannot downgrade a device to some older version. So when 3GS became insanely slow with updates, no one could at random get a device with an old OS version.
    - Spare_account 9y ago
      This is a weak argument. It takes literally zero planning to do a test now and then do another after the update. I've found a few examples here: https://www.youtube.com/user/kabriolett https://www.youtube.com/user/kabriolett These don't support the argument that devices are slower after updates.
gruturo 9y ago
My biggest gripe is the flashlight delay - swipe up for control center, tap flashlight, and the actual light takes easily a third of a second to turn on. I suspect that's also waiting for the stupid animation to complete. Honestly I feel like the people in charge of iOS have stopped using the devices personally. I have no other explanation for so much annoying crap slipping through (ok, other than some idiot exec being in love with the animations, and shutting down any attempt to correct this behaviour, like what happened with Forstall's obsession with skeuomorphism).
- joosters 9y ago
  The flashlight behaviour is odd, I just tried it and I got the same delay the first time I turned it on, but no delay after turning it on multiple times. It's almost as if the code was swapped out to a slow disk and you have to wait for it to be swapped back in before the first use. There's still no good reason why it should take such a noticeable time, though.
  - tzahola 9y ago
    There's no swapping on iOS. The delay is probably caused by iOS lazily waking up some hardware. The same happens when you use haptic feedbacks: >Calling the generator’s prepare() method puts the Taptic Engine in a prepared state. To preserve power, the Taptic Engine stays in this state for only a short period of time (on the order of seconds), or until you next trigger feedback. https://developer.apple.com/documentation/uikit/uifeedbackgenerator https://developer.apple.com/documentation/uikit/uifeedbackge...

> My immediate thought was that Apple had liberally sprinkled wait() into the iOS 11 code base so that I'd feel like my ole A9 CPU just wasn't cutting it any more and I'd realize, as they do, it's time to upgrade. Which would affect the 2017 iPad also. Why introduce a new iPad with the A9 if you're going to limit the performance. Is it to get people to buy... what exactly? An iPad Pro? Why not simply ONLY make iPad Pros? This line of reasoning is immature and beneath the type of discourse that should occur on any tech leaning site. I really hope you're just being sarcastic and mocking everyone who really thinks this. Edit: I, personally, have a 6S and it's fine. Of course I DFU and set up as new for new OSs. It's even better on 11.1 beta 5.
napsterbr 9y ago
Same here. I had bought my 6s after my 6 got stolen, so it was my first time using iOS 11. My two-day old phone was absolutely unusable, freezing for over a minute every once in a while. Apps wouldn't open at all! I couldn't change the volume while the phone was locked. I couldn't listen to musics, or use the lock screen music handler, while the phone was locked. You have something really wrong when your smartphone can't open apps... After one week I got tired of this shit and downgraded to iOS 10, which for now is working as expected. I really hope apple won't force me to update to iOS 11. (So here's what I did: I intentionally filled my phone space. Good luck fitting iOS' 1GB here). Frustrated disappointed and utterly angry at Apple. This is definitely the last iPhone I'll own.
sholnay 9y ago
I was using a 6 Plus up until a few weeks ago. Every upgrade caused serious performance decreases and I avoided iOS11 entirely (anticipating an upgrade to a new device). My partner upgrades yearly and I gave up all phone tasks to him when we were out together as my performance was so bad. Unlock? slow. Open chrome? 2-3 seconds. Open safari? 2-3 seconds. Fancy webpage? Forget it. We use google keep a lot, it basically didn't work on the 6 Plus. Sometimes the app would load quickly, sometimes it would take minutes or not load (or maybe if I kept waiting, it would eventually?). Scrolling in the app hardly worked. Screen touches became more hit or miss. Reflexively, I built in a 2-3 tap routine for most screen touches as it took that many for them to register. Scrolling any sort of content was difficult, stutter-y, and inconvenient. Siri didn't work - but I'm not sure if it does now either. I also had all animations off in an attempt to squeeze some performance. Anyway, whatever apple did or didn't do, worked. I upgraded to an 8 Plus and couldn't be happier. I run in to others who have version 6 phones and have no problem, so I don't know why I'm an outlier. Part of it is probably my storage habits, I was almost always within 5-10% of capacity. Now I have 256gb version and am hoping I don't get near the limit so that this phone will last me 3 years.
koffiezet 9y ago
Strange, I see little to no difference on my 6S. I was considering getting an X, but since my phone still handles iOS 11 perfectly, I don't see any reason to upgrade. I'd try restoring my phone if I were you - that fixes these issues for a lot of people.

I'm on the 6, two years older than that, and experience lag but never a single stutter on anything audio related. It sounds like an issue that a reset or reinstall may fix. I'd be similarly pissed off like you if even my much older phone did that.

The worst thing for me is the Camera. If I want to take a photo of something that's just happening I don't even bother anymore since I can expect it to take 10 seconds to wake the phone, get into the camera, and have the shutter button respond and have it actually take a photo (sometimes it looks like it took a photo but it actually didn't save!).

balls187 9y ago
Interesting. Bored before bed so ran a quick test using my iphone7 and Ios 11.x, Google's stopwatch. The time from wake to photo was ~2seconds (using the lockscreen short cut). The time from wake to home screen photo app to photo was ~5 seconds. * I had to start the timer myself then go back to using the phone so I believe I could cut ~500ms. Since I have Live Photo enabled, the 2-second shots actually have a few frames that are sub 2 seconds. Going to the homescreen was accidental. In each attempt, I attempted to use the lock-screen camera shortcut. As a whole, the experience using the iphone is too unpredictable to be reliable for quick reaction shots (< 3 seconds). A number of times I either: bypassed the lock screen, didnt get passed the lock screen, unlocked my phone to a different app, and on one occasion, the camera app paused for a few seconds before focusing.

  I really miss Samsung's 'double-click home button to use camera' on the Galaxy S6 and S7. Probably the most convenient implementation of a camera shortcut I've seen.

    I like the Motorola double twist for camera gesture, you can start the gesture just as you take it out of your pocket.

It takes 14 sec to open maps and load a screen of tiles, 4 sec to open messenger on a my 6 plus. I’d love to see timings for this on the newer models. Also, I swear the rear-facing camera has lower color saturation and higher sensoe noise after the upgrade. I’d love to see A-B camera tests for iOS 10 and 11 on old hardware.

Opening iMessage on a 6s Plus running iOS 11.0.3: Two seconds
- lloeki 9y ago
  This kind of thread generally piles up on rants of frustrated users, so here's another data (counter-)point: both are <1s for sure, possibly even less than 0.5s on my 6S w/ iOS 11, from a cold start. Everything is snappy and responsive, enough that I'd have to film this on slow mo and time it to be sure of any delay metric. Overall iOS 11 has been a solid performer for me ever since the second public beta.
  - submeta 9y ago
    I wasn't complaining at all. I love iOS 11. Just wanted to give some input.
    - lloeki 9y ago
      Sorry for the misunderstanding, this wasn't aimed at you at all, I just responded to yours because you mentioned timings on a same gen device as mine and it seems mine is significantly faster. As for the rest, it's just that the sarcastic, conspiracist, passive-aggressive tone of many of the sibling comments is unnerving.
      - napsterbr 9y ago
        What exactly my tone should be? I bought a very expensive phone that was unable to launch apps (50% of the time, when it did, it took several seconds) and unable to make calls (the receiving end would be mute and would not hear what I was saying). The phone was bought on an official apple store and had one day of use. Problems persisted for over a week. Tried all the possible solutions. The only one that worked was downgrading to 10.

kayoone 9y ago

This. My 6 Plus is barely usable now, to the point where it is annoying the hell out of me. On iOS 10 i was fine with the 6 Plus and thought i could easily use it another year, but right now it's barely usable. I compared loading a banking app on my 6 and my colleagues 7 (closed it before) and the difference is astounding (2-3 seconds slower). Also everything is just laggy including typing and taking photos.

ballenf 9y ago
I have the 6 and benefited from uninstalling 3rd party keyboards and doing a settings reset. Might have also done a fresh install. For a 3 year old phone, it's frustrating but still miles ahead of the last Android phone I kept for 18 months. It's still frustrating that the iOS update is basically forced on us instead of being an optional upgrade like on desktop. (Of course it's technically optionally, but the constant nag annoyance makes it effectively forced, imo.)
pault 9y ago
Odd, I have a 6s Plus and I haven't had any issues after upgrading. Sounds like it's hit and miss. I wonder if they changed the hardware during the production lifetime.
- kayoone 9y ago
  6S has the A9 processor, the 6 has the A8, maybe that makes enough of a difference for it to not be that bad. I will also try the complete reset though.

> My immediate thought was that Apple had liberally sprinkled wait() into the iOS 11 code base so that I'd feel like my ole A9 CPU just wasn't cutting it any more and I'd realize, as they do, it's time to upgrade. That was actually recently debunked by Futuremark https://www.futuremark.com/pressreleases/is-it-true-that-iphones-get-slower-over-time https://www.futuremark.com/pressreleases/is-it-true-that-iph.... Important excerpts found at the bottom of the page: > Our benchmarking data shows that, rather than intentionally degrading the performance of older models, Apple actually does a good job of supporting its older devices with regular updates that maintain a consistent level of performance across iOS versions. and > That said, there are some factors that might affect people's perception of performance after updating an older device with a newer version of iOS. An update might add new features that use more resources or require more processing power. New apps developed for the latest models might not run as smoothly on older devices. Conversely, apps designed for an earlier version of iOS might not take full advantage of optimizations in the latest version. And then there is always the psychological effect of knowing that there is a new and improved model available, which can make your own device seem outdated.

What is debunked? That the CPU has not changed during the upgrade? No shit sherlock. Synthetic benchmarks tell nothing of the end-user experience. Does Apple sprinkle wait()? No. Does the system become more and more complex and Apple taking less time to optimize because it runs “fine” on the [latest - 1] hardware? Yes.
- zimpenfish 9y ago
  Technically the 6s is now [latest - 2] hardware. X/8/8+ have the A11 Bionic; 7/7+ have the A10 Fusion; 6s has the A9.

More annoying than performance is the ever increasing nagging for apple paid services, apple pay, apple icloud, etc. The platform is literally becoming a junk adware platform. It feels like an infected PC that pop ups ads randomly.

Naomarik 9y ago
This is precisely why I will not buy an iPhone again. Every single time I open my photos to show someone something I have to wait through two popups that are extremely slow to close. Also now I'm getting nagged to upgrade to ios 11 whenever I just want to use the phone. Abysmal.
- nvarsj 9y ago
  What's the alternative? Android, especially Samsung infested bloatware, is substantially worse. The touchwiz upgrade prompts are WAY more annoying than ios ones. Plus the constant Samsung login junk. And then there is the heavy google integration that requires a google account for almost everything.
  - Naomarik 9y ago
    Except it isn't worse. Not anymore anyway. Any and all notifications just go up top and don't prevent you from using the phone -- even if someone calls you. My 3 year old Sony Xperia Z1C that I only use to for testing lets me jump into whatever app I want as soon as it starts immediately even though I can see there's like 50 notifications to go through. But I can do that when it's convenient for me. My main problem is that if I simply want to do something on any iOS now as soon as I unlock it I'm blocked by pop ups for things like making a back up and buying more iCloud storage and upgrading to iOS 11 -- things I never intend to do. There's no way to switch these off either. And they happen constantly, multiple times a day. Last time I used my iPad I dismissed a popup, opened up an app and the same pop up came a few minutes later completely interrupting me. I have no tolerance for these annoyances. Samsung phones were complete trash back in the day with their bloated interface but I've since switched to a Note 8 and the experience has been very good. UI is very clean and the performance/features on the phone are outstanding.

dvfjsdhgfv 9y ago

Unfortunately, this is a sad but regular scenario now. It doesn't matter whether Apple does it on purpose or simply doesn't care, but new versions of iOS degrade the performance of older devices (an in this case "older" doesn't necessarily mean "very old"). Some people simply choose not to upgrade, but this may have security implications - and in any case sooner or later you'll come across an app you need that doesn't work on an older version of iOS. You will upgrade, the performace will be degraded, and your previously "good enough" device will suddenly feel sluggish and old.

Spare_account 9y ago
Is there any definitive evidence for this? Has anyone benchmarked devices before and after upgrades to prove it? Edit: I don't mean CPU benchmarking which has been discussed elsewhere in this thread. More like usability testing, sequences of actions not invoking new OS features where possible, and also a second set of tests using new OS features because that's what most people's experience would be.
- orloffm 9y ago
  It's difficult to achieve because one cannot downgrade a device to some older version. So when 3GS became insanely slow with updates, no one could at random get a device with an old OS version.
  - Spare_account 9y ago
    This is a weak argument. It takes literally zero planning to do a test now and then do another after the update. I've found a few examples here: https://www.youtube.com/user/kabriolett https://www.youtube.com/user/kabriolett These don't support the argument that devices are slower after updates.

gruturo 9y ago

My biggest gripe is the flashlight delay - swipe up for control center, tap flashlight, and the actual light takes easily a third of a second to turn on. I suspect that's also waiting for the stupid animation to complete. Honestly I feel like the people in charge of iOS have stopped using the devices personally. I have no other explanation for so much annoying crap slipping through (ok, other than some idiot exec being in love with the animations, and shutting down any attempt to correct this behaviour, like what happened with Forstall's obsession with skeuomorphism).

joosters 9y ago
The flashlight behaviour is odd, I just tried it and I got the same delay the first time I turned it on, but no delay after turning it on multiple times. It's almost as if the code was swapped out to a slow disk and you have to wait for it to be swapped back in before the first use. There's still no good reason why it should take such a noticeable time, though.
- tzahola 9y ago
  There's no swapping on iOS. The delay is probably caused by iOS lazily waking up some hardware. The same happens when you use haptic feedbacks: >Calling the generator’s prepare() method puts the Taptic Engine in a prepared state. To preserve power, the Taptic Engine stays in this state for only a short period of time (on the order of seconds), or until you next trigger feedback. https://developer.apple.com/documentation/uikit/uifeedbackgenerator https://developer.apple.com/documentation/uikit/uifeedbackge...

> My immediate thought was that Apple had liberally sprinkled wait() into the iOS 11 code base so that I'd feel like my ole A9 CPU just wasn't cutting it any more and I'd realize, as they do, it's time to upgrade. Which would affect the 2017 iPad also. Why introduce a new iPad with the A9 if you're going to limit the performance. Is it to get people to buy... what exactly? An iPad Pro? Why not simply ONLY make iPad Pros? This line of reasoning is immature and beneath the type of discourse that should occur on any tech leaning site. I really hope you're just being sarcastic and mocking everyone who really thinks this. Edit: I, personally, have a 6S and it's fine. Of course I DFU and set up as new for new OSs. It's even better on 11.1 beta 5.

napsterbr 9y ago

Same here. I had bought my 6s after my 6 got stolen, so it was my first time using iOS 11. My two-day old phone was absolutely unusable, freezing for over a minute every once in a while. Apps wouldn't open at all! I couldn't change the volume while the phone was locked. I couldn't listen to musics, or use the lock screen music handler, while the phone was locked. You have something really wrong when your smartphone can't open apps... After one week I got tired of this shit and downgraded to iOS 10, which for now is working as expected. I really hope apple won't force me to update to iOS 11. (So here's what I did: I intentionally filled my phone space. Good luck fitting iOS' 1GB here). Frustrated disappointed and utterly angry at Apple. This is definitely the last iPhone I'll own.

sholnay 9y ago

I was using a 6 Plus up until a few weeks ago. Every upgrade caused serious performance decreases and I avoided iOS11 entirely (anticipating an upgrade to a new device). My partner upgrades yearly and I gave up all phone tasks to him when we were out together as my performance was so bad. Unlock? slow. Open chrome? 2-3 seconds. Open safari? 2-3 seconds. Fancy webpage? Forget it. We use google keep a lot, it basically didn't work on the 6 Plus. Sometimes the app would load quickly, sometimes it would take minutes or not load (or maybe if I kept waiting, it would eventually?). Scrolling in the app hardly worked. Screen touches became more hit or miss. Reflexively, I built in a 2-3 tap routine for most screen touches as it took that many for them to register. Scrolling any sort of content was difficult, stutter-y, and inconvenient. Siri didn't work - but I'm not sure if it does now either. I also had all animations off in an attempt to squeeze some performance. Anyway, whatever apple did or didn't do, worked. I upgraded to an 8 Plus and couldn't be happier. I run in to others who have version 6 phones and have no problem, so I don't know why I'm an outlier. Part of it is probably my storage habits, I was almost always within 5-10% of capacity. Now I have 256gb version and am hoping I don't get near the limit so that this phone will last me 3 years.

koffiezet 9y ago

Strange, I see little to no difference on my 6S. I was considering getting an X, but since my phone still handles iOS 11 perfectly, I don't see any reason to upgrade. I'd try restoring my phone if I were you - that fixes these issues for a lot of people.
