11.0.3 update has ruined My iPhone 6s speed. It was super quick and perfect before the install. Now it takes 3-5 seconds to open all apps. Its RIDICULOUS.

Writing texts is painful. You click on the keyboard and there is a huge lag.


It’s honestly as slow now as a phone from 10 years ago. Apple customer service so far have been useless just asking for the same details over and over (what country, what apps are affected, when did I do the update blah blah)


Apple broke my phone with their poorly tested update, yet they’ve issued no software fix. Nice way to respect your millions of customers Apple.

Already wrote one long post but put mt gripes in wrong place. Apple gave topics to choose from... updates and troubleshooting not on there👥.

So, gist is 11.0 e has just about rendered my 6 Plus useless. So many bugs... I don't know if they were drunk as monkeys, too high or got sabotaged.

BOTTOM LINE: I'm 65, on oxygen 24/7, need dbl lung transplant...(you get 2 hr or less notice to get to hosp), have cable phone that goes out... this phone has been my lifeline. ATT & Apple... they've never given me one minutes problem. Dependable.

Is there anyway to remove 11.0 update and go back to 10 Or less? My asst. worked at Apple for 2 yrs... she's bumfuzzled! *** Apple? You think $900. Grows on trees so why not hire unqualified QC ppl from Russia? Determined to intercept our communications? Get it fixed... your consumer base is dwindling!

Identical issues with my iPhone 6 Plus after installing 11.03 (Running 6.17.00 Firmware).

- Keyboard responsiveness is slow

- Games are laggy and unplayable

- Toggling between apps causes some apps to crash and others take seconds to open.

- Opening a message directly from a lock screen is not possible. All I get is a white screen and I have to unlock the phone, quit message and start again.

- Battery Life is noticeably shortened

I thought it was just my phone because it was out dated but it sounds from this string that 6S, 7S & even 8 are being hobbled but the OS.

When will they announce a fix?

Has their been any recognition from Apple that they're destroying the usability of their hand sets?

I thought it was just me but I see that I am not the only one suffering from this garbage update by Apple. My iPhone 6s was running a lot smoother before this latest update and now it's even worse than the initial iOS 11 update. Apple, WHEN ARE YOU GOING TO FIX THIS?! EVERY app is sluggish and there is a delay with response times to opening ANY app and clicking ANYTHING!!!

Here’s a FIX that someone from another thread suggested and it has worked for me.


Go to Settings, Reset, and select RESET ALL SETTINGS.


This does not wipe or erase any data on your phone but it does erase all of your phone settings such as WiFi, Notifications Settings for each app, passcode, fingerprint, wallpaper etc. So mainly the phone function settings only. Stuff like email, apps data, contacts and all the data oriented stuff will still be there.


But you should definitely do a backup before you reset.


All in all, it took about 30 mins from the time I pressed RESET ALL SETTINGS to the time I had to go enter in all of my original phone settings. But my phone seems to be working as fast as it was before the IOS 11.0 upgrade...thank goodness!


Good luck all!

I have an iPhone 6s Plus, but I’m having the same problems too. Apps crash, messages don’t come through, the entire phone will freeze up multiple times a day, and the worst part: my battery is being sucked dry while the phone does nothing at all. Before I would get through most of the day before needing to recharge (or take a battery pack out with me), but now the phone will last maybe three hours tops — and that’s reducing every battery draining app possible and changing all my settings to help preserve power. I basically have to keep it plugged in all the time now, I just had to buy a new mophie for it, AND I STILL have to carry a portable battery pack charger with me when I’m not in my office.



I see where Apple is going with this update, and I see the promise and features they want (which is great!), but it’s obviously flawed and shouldn’t have been made available to anyone with a phone older than an iPhone 7 until the bugs were solved.



I’m in the middle of running an election right now, and just to get me through, I’ve had to go out and buy an Android phone so I can actually receive messages and phone calls. This is insane.



I’ve already contacted support and I purposely left my case open so I can file complaints with the state and federal governments, so they can look into the issue on a consumer level; I’ve also done it in Canada where I’m working right now.



Yeah yeah, I get it, Apple wants me to upgrade to a brand new iPhone, MacBook Pro (admittedly, it does need to be upgraded), upgrade to a new iPad Pro, and to upgrade my two year old iMac. I *get* it. But I bought the phone outright from an Apple Store, and I still have to pay Verizon for service each month.



Apple, please fix this. Filling out consumer complaints with the correct agencies is something I actually enjoy doing, because I’ve never had an agency turn my request down. Please don’t make me waste my weekend doing that.

Do not count on Apple releasing a patch. They want you to upgrade to a new phone. A company the size of Apple conducts thorough testing before releasing a new ios version. They know exactly what they are doing. They are forcing customers to purchase a new phone. And for those who do not upgrade right away, they know the sluggish phone will ultimately mean those customers will upgrade faster. They do not care that we are not happy, they actually like it, because they know customers will keep upgrading. It may be time to say goodbye to Apple.

It’s simply time to just boycott Apple. We’re beating a dead horse at this point. The company died with Steve Jobs- everyone knows that. Apple just wants to make more money by forcing consumers to buy their “new” and “shiny” improvements, including their faulty updates which slow your phone down either way. The person/team who decided to take out the ear jack will unfortunately suffer the consequences. They don’t know our generation AT ALL. Just don’t update your phone, or go back to the flip phone.

So i've just done the 11.1 update thinking, hallelujah, at last Apple have released the fix for breaking our iphones by making them slow and a nightmare to use. Erm.....


IT'S FIXED NOTHING!!


My iPhone 6 is still laggy, slow, and the volume button doesn't work properly (phone rings as if on 70% volume even when put down to 5%).


Oh, but they have given us new emojjis in the update....way to go with you fuc*ing priorities Apple! (***??)


I am 100% never buying another iPhone after this. I'm sick of Apples disregard for us customers.
