iOS 11 update has slowed down older iPhones (Poll Results)

The Apple iOS 11 software update was one of the biggest changes to the system, bringing a lot of new functionality and a brand new Control Center to iPhones, but initial reports by many suggest one thing: it has made older iPhones (iPhone 7 and earlier) stutter and run very slowly.

To double-check whether this is indeed true for the majority of users, we asked you, our readers, to share your impressions with your iPhones after the iOS 11 update and the results of the poll are in: the overwhelming majority of users of older iPhones do notice some form of slow-down or stutter when using their devices.

Some 31% see a really bad decline in performance on their iPhones (that's what we've witnessed on iPhone 6 as well), then nearly 25% say that they do notice more stutter, but that the issue is not severe. Then, 23% of users actually report that their iPhones are working just fine and they do not notice any drop in performance. Keep in mind that the iOS 11.1 update seems to fix stutter issue on some devices to a certain degree.

Finally, we had a large and curious Android crowd overlooking the results and enjoying their platform.

Overall, it's definitely not Apple-like to have such issues with speed and performance after an update, especially to the degree we see reported on iOS 11. Let's hope for a fix.

Did the iOS 11 update slow down your iPhone?

Yes, it stutters really bad now
Yes, it stutters slightly more
Nope, still runs well
I use Android ;)

I noticed severe lag on iphone 6s plus. Can't speak for other phones

7+ wasn't great on 11.0.3, 11.1 betas were all a vast improvement bet then again the 7+ was so slow on 10.0.X because of the weird app closing animation.

Can we all agree this poll was silly? 3301 total votes. Here are the conclusions based on the information: 699 (or 20%) are Android users 2602 (or 80%) are iOS users No way 80% of voters are actually iOS users on a PhoneArena poll. Not saying all the reported info is false, but it's valid to mention that fanboyism substantially affects these polls.

I think across the board on devices running any newer OS than what came out of the box, the device tends to run slower. I've had all kinds of phones from many different manufacturers and OSes and they all seemed to slow down with each new iteration of updates. I think it has to deal a lot with the manufacturers simply putting an update out there instead of tailoring it to work on a multitude of different hardware.

I have never had one of my Samsung phones slow down with any of the updates with AT&T, and that is why it doesn't bother me that they are slow with updates. I also wait tell its been out a few weeks just in case.

My experience has been OTA updates cause more issues than when I use iTunes. But my typical upgrade path is, backing up my phone to the cloud, then to the PC. Factory resetting the phone and then placing the phone in DFU mode and manually downloading the firmware and installing it and then restoring my backup. Long process, but usually caused less issues. Since iOS9, doing this path has resulted in the same benefits it did in the past. With iOS9, I didn't upgrade this path with each update because it was just to many. Now when doing OTA updates, its been terrible. I use a similar path when doing my Android. But even when I just do OTA updates, my Android hasn't ever gotten slower, or faster. It simply remained the same. Same speed, same battery-life same everything. Apple updates are quick, but poorly done. The iPhone 7 isn't that old. Its only been a year. If this update made the iPhone 7 slower, then either the update sucks or the hardware sucks.

I can say the same about android based polls

No, because there much fewer Apple users on this website than Android users. Apple has like 13 to 14% market share. It is statiscally impossible that Android polls can be biased in the same way as iOS related polls.

And you know this how? Market-share has NOTHING to do with how many of each use this site. You must be high. Even though there are more Android users in general, you don't need to be registered to vote. Thus you have zero idea how many Apple users just visit and click, read and leave. There can be 10,000 visitors of each evenly and that still doesn't mean any one side will vote more vs another. If you don't agree with the poll than don't. But your BS explanation is just that. I use and own both phones, so which way did I vote. Any idea? No you don't. I actually didn't vote at all. So your point is baloney.

Maybe, but quite a few of them have 4 or 5 accounts.

80% of voters on an iOS poll can be iOS users IMO. I didn't click the link since I am an android user(and not switching ever).

Couldn't agree more!! Well said. PA is plagued with a massive Android trill infestation. Sadly it is quite epidemic in to this particular website. These polls are so useless and thus must be just for recreation purposes only.

But you believe every Apple poll where Apple wins though. Yeah because it only matter when its good and not bad! lol

When the vast majority of YouTubers are reporting lag, app crashes, shutters. Then that speaks volumes. Especially when lots of those YouTubers are Apple sheep.

You are absolutely right. The poll result must be heavily biased by Android OEM fanboys trying to make iOS look bad. What is wrong with people? We speak about stupid smartphones. There is no reason for such hate. Apple must have broken many hearts on this website to provoke such reactions.

And I guess apple fanboys NEVER vote in Samsung/android polls.

Never said that. I'd 100% agree that polls are flawed no matter the platform.

Android users don't need to make IOS look bad. It dos that quite well on its own. The fact you're tuning a blind eye to it, speaks volumes.

Not necessarily. Many Android users might not have voted.

A super butthurt fanboy's whining about fanboyism.... now that's funny

My guesstimate of PA users based on the comment section is: 85% android users, 15% ios users.

So, pretty much mirroring the actual world.

iOS 11 slowed down my 7 plus drastically.

You can literally see all the complaints on social media. On Twitter, I kid you not, I see people every single day complaining about their iphones doing crazy stuff after the updates. Every single day.

Well...iOS 11.0.x indeed slowed down iPhone 7. Battery life is still worst compared to iOS 10. Stutters are gone with iOS 11.1.

Yeah, because owning Android device and iOS device at the same time is forbidden /s

My iPad Pro 10.5 is faster with smoother performance since 11.1. Battery life is also superb. The only problem I have is with Hill Climb, it has been crashing since iOS 11 was released, but other than that, my experience has been great.

That's good to hear. I've experienced the same with my 10.5. Getting 12 hours of SOT with mine.

24. maherk

Posts: 7050; Member since: Feb 10, 2012

Same here. Never got below 11 hrs of SOT. And all I do is game a lot, watch YT, and stream movies on it. Hoping next generation will have 16:9 aspect ratio and an AMOLED panel. I know I am asking for a lot, but maybe my wishes will come true.

Android for life...but damn that ipad pro is so tempting.... One day
