iPhone 6 very slow with IOS 11 update

After receiving IOS 11.01.1 on my MGCT2LL/A1522 (iPhone 6), my phone is super slow. Apps hang, then close (like the Starbucks app), my purchased music would just stop in the middle of a song, then I had to close the app and re-open.

In general, everything is very slow to respond, and I have rebooted twice.


Any suggestions

HERE'S THE FIX: Go into Settings> General> Reset> Reset All Settings (this will reset iOS settings, won't touch your apps)


WHAT THIS DOES: This will *not* erase your phone, but will reset most of the things you can adjust in settings on iOS (you'll need to re-enter you wifi, adjust notifications and privacy settings again, reset your default account for Calendar and Notes, etc, but all your email accounts and iCloud account will still be logged in and all working).


FIXES THIS ISSUE: I had the same issue: iPhone 6S. Upgraded. Even with 25GB free, I'd press a button and often have to wait 1-3 seconds for a response, or copy and paste selectors would be really slow to appear, even the keyboard was unresponsive... phone was barely unusable, literally. I think most people don't get it because most who updated to iOS 11 noticed it being a little slower but not 90% slower. Those like us need to take this step.


BACKGROUND: When I was scouring I found that erasing your phone and restoring from backup worked for people on Reddit, and that should be reliable. I was in the process of doing that myself and accidentally chose "reset all settings" instead of "erase all content and settings". My phone rebooted and all my apps are fine, just needed to go through iOS settings and readjust things.


ALTERNATIVES: This is obviously better than either (a) downgrading to iOS 10 or (b) making sure your phone (as it is now on iOS11) is backed up to iCloud, erasing it, and restoring from that backup.


The difference in speed is shocking.


Pretty sure this will work for you too.

I guess i spoke too soon. My advise to all who are not at ios 11.2 yet..stay put where you are till and if Apple fixes it in their next version. Hopefully soon!

Was reluctant to upgrade to 11.2 after facing all the issues with 11.1, but when I read that 11.2 will fix it i went ahead and updated. first 2...3 days i was thrilled as it looked like my iphone 6 was fixed. But 5 days later i again see the lag starting. i am sure its getting worse! I can go and buy a Galaxy S8 today but want to wait till march for S9. So now i have 4 months of suffering and pain to go through with this half dead phone or ios!
Thank you Apple!

Hi elp,

Sorry to hear that 😟

Regarding the Galaxy 9, I just got the 8+ and was assured I would get VoLTE coverage but the device doesn't support it. I found out the S5 and S6 do but beyond that, no. So, just a head's up on that. Your carrier may offer by then but definitely check to see if the S9 will/if the device itself supports it (mine has LTE but that's not the same & my phone never picks up LTE regardless), as I was quite angered when I had to find out after the fact, especially when I specifically stated I needed this coverage and they assured me I would have it with the S8+

It's rare that I'm able to use my phone as a phone. I think Sprint may offer one that supports VoLTE however

- I've had luck with my iPhone with call completion, reliant on cellular only, but I use it in a different location and rely on 4g which works great in that zip code and surrounding area (same carrier)

- I really like both phones overall however and use one for work, the other for personal.

I just wanted to share this with you in case coverage (GOOD coverage such as VoLTE) and holding a call is important to you as well as processing data of any type.

Take care ~

This about Galaxy sounds a bit off-topic, but anyway ... are you using an MVNO or a major carrier? You said you are not able to get LTE which is very strange. Usually this happens when you use an MVNO. The phone then doesn't know how to set the APN settings, and usually you need to do it manually. See: https://bestmvno.com/apn-settings/



Also, MVNOs usually cannot do VoLTE or VoWifi. I've confirmed that with AT&T, TMO. MVNOs are cheap, but that's the trade-off: LTE OK. VoLTE, VoWifi no.

Lol, it does but I felt I had to let him know what happened to me, to my great surprise.

I use Tmobile...definitely a major carrier. Sr tech told me VoLTE as advertised isn't supported on the newest Galaxy devices but is on the iPhones.

I have lte/4g/3g option checked but it's a big deal if I get 4g at home and surrounding area. It's not picked up LTE. I'm essentially reliant on WiFi calling which is also unreliable....

But, looks like I'm stuck with it

I have an iPhone 6 Plus and let’s face it, I personally dont need the latest greatest, nor can I justify buying a phone dwarfing the price of a new decent laptop/desktop computer.


There is NO reason to cripple phones purposely to incentivize/forcing the purchase of a new Apple iPhone.


I am so disappointed by Apple. For me it’s only a phone, why would you slow it down purposely that even the phone function becomes annoyingly slow to use?


I understand it is all about cash for Apple but you should be accepting of people that don’t want to have a new phone every two years. This is not a financial issue for me at all. Let me decide when I want to buy a new phone, stop dictating when you think it’s time for me to buy a new phone, by making it purposely painful to work with after an update.


This is absolute BS, really.

We have been promised a "fix" via 11.1 since October 1st. We are now December 10 and no solution in sight. My iPhone 6 went from being a useful device, to essentially a brick. Each and every action is slow: selecting a calendar event, entering a calendar event, reading an email, reading a message ...


And those are the productivity apps I use all the time. Don't get me started with other (non-Apple) apps. Forget about tweeting: just typing a tweet is slow. Good thing is that I no longer waste time with my Solitaire app. It is just unusable.


That is a general trend with Apple over the last few years for iOS: bring up a new version with a few useless cosmetic changes and a major loss of performance (and sometimes of functionality). Clearly this version (11.0) was not at all tested on current devices (iPhone6) by any real user.


BTW the same applies to MacOS and the MacBook Pro laptops ... it's all a constant downhill in terms of design and quality. I used to be a strong Apple users, and so is my family: between all four of us, we have four MacBooks, four iPads, four iPhones, and also a couple of MacBook Airs ... But enough is enough.

All - I've had my iPhone 6 for over 3 years now and I've taken very good care of it (it looks brand new) and I have faithfully made all of the suggested iOS updates to my phone. But ever since I updated to iOS 11, my iPhone has been super slow and no longer enjoyable to use. I've read all of the postings here and I have tried all of the suggestions for speeding up my phone, but nothing has helped. So I'm almost ready to throw in the towel and buy an iPhone 8. I think the moral of the story is to be wary of any operating system updates on iPhones, iMacs, and iPads.


So in general, is it better to NOT update an older iPhone to a new operating system? (By "old" I mean any iPhone that is 2 1/2 years or older.)


I used to be a big believer in Apple products, but my recent iPhone experiences has shaken my faith. 😟 I'm holding out hope that someone at Apple (or an Apple user) will be able to restore my faith and show me how to speed up my phone. I don't expect it to be as fast a new iPhone, but somewhat faster would be nice.

Thank you sir, i’ll take a subscription to battery change every 9 month and miss my phone for 10 days in the meantime because that’s the best service Apple gives me.

I’ll stop whining because you are right, there’s nothing abnormal about this, it’s common sense to change a phone battery that often. All iPhones, phones, and other mobile devices from every brand are like that.


Excuse me I wanted to share information but in reality i’m Just a foul.

PS: all my excuses to Sir Ive, i’ll Erase my post if that’s possible.

Hello,


i am on ios 11.2 and my iphone 6 has occasional lags phone becomes so slow...i have spent a lot of money on this and my experiance is terrible..its so slow sometimes i will sell this phone and wont recommand apple products to anyone in future.. i also reinstall everything m a software engineer too by profession i just hope some 11.3 updates will solve this issue or i m selling this disaster phone

Dec 12, 2017 6:37 AM in response to El Paso Steve

I also have an answer: ditch Apple and go with Android; take a look at how much searches for "iPhone slow" spike every time there's a new release with Apple and then compare that with Android's releases... you don't see this massive spike in their users searching for solutions to why their phones are suddenly slow or a mess. I'm so done with Apple. The features are always a year or two behind the other guys and they have the arrogance to pretend they invented everything. They're a slow-follower who acts like they're the innovator-leader in their market. And you pay more for the privilege.
