iPhone 6 very slow with IOS 11 update

By the way everyone, there is an issue with some iPhone 6S phones where Apple will replace the battery free - my phone was eligible. Its for 6S phones made Sept Oct of 2015 you can check if your phone qualifies for the free battery here iPhone 6s Program for Unexpected Shutdown Issues - Apple Support

I wanted to follow up on my 2015 iPhone 6S under the free battery replacement program by Apple. I went into the Apple story yesterday and they couldnt have been nicer. They checked my phone and my phone qualified for a free install of a new battery. The phone would not power on after the install so they gave me a brand new 6s with a 90 day warranty. Whole thing to 70 minutes 3 days before Christmas. You can see if you are eligible here iPhone 6s Program for Unexpected Shutdown Issues - Apple Support

This, as most of us here already suspected was a deliberately engineered slow down and has now finally been admitted: Statement.....

So time to get in the queue for a new replacement battery.

I still think the user should have the choice of whether to throttle the CPU / GPU performance though, as this is the one main thing that is making the phone unusable for me - the slow laggy display and response times of doing nothing more than trying to scroll through an email - forget Landscape zooming in Safari, it just freezes, App store won't load - takes 2-3 times of closing it before it opens. All immensely annoying.

So thank you for the apology Apple, though a long time coming.

Same problem.

Even you can check the below thread :

Re: display response delay during incoming call

This is frustrating and irritating now.

Apple users are not fool.

APPLE - PLEASE ESCALATE THIS TOPIC AND FIX THIS IN THE NEXT RELEASE.

Just curious, apart from the slowness, is anyone seeing unusual Cellular activity ? For example, does it appear to use more cellular data than before, even when you're supposidly on a good WiFi connection ?

I've raised that matter in another thread -

Good Luck to You!

I have an iPhone 6 and have also had terrible performance since updating to iOS 11. There are many symptoms:

• Apps open up slowly and stutter.
• The keyboard opens up slowly and there is keyboard lag.
• The phone and keyboard freeze when Messages or Mail try to autocomplete addresses.
• The phone regularly becomes unresponsive for a few seconds at a time.
• I often have to tap buttons three or four times before I get a response. For example, in the Maps app after I get directions I have to tap on the "go" button over and over before I start getting directions.

iOS 11.1 and iOS 11.2 have not helped.

I did a factory reset and reinstalled iOS and all my apps and data and that did not help.

I have an iPhone 6 with 64GB of RAM. I have 32GB of available space. My battery is fine, showing only 14% wear. (Of course, having an old battery shouldn't kill performance, but apparently there's some evidence it does that.)

Apple needs to fix this problem. Even if it was not intentional, it looks like they are slowing down old devices to push people to new ones. They need to fix it.

You go to bed and turn off your phone at about 43% battery remaining, leaving it on the table.

Why aren't you plugging your phone in at night? If you plug your phone in at night, make sure it's connected to WiFi and the screen is locked, your phone will be backed up to iCloud (assuming you have that turned on) and will be charged and ready to go in the morning. Also, you won't need to risk damaging your phone by putting it under a heater.

The temperatures you're citing are within the operating range of the iPhone. Therefore, if you're phone isn't working at those temperatures, there's something wrong with it.

Environmental Requirements

• Operating ambient temperature: 32° to 95° F (0° to 35° C)
• Nonoperating temperature: ‑4° to 113° F (‑20° to 45° C)

You raise good points. This is by way of explanation, not a justification.

• The technical support reps are not permitted to say anything that has not been approved by Apple Legal and included in their support scripts. [Apple is not alone in this; all large companies do it]
• Six weeks ago this was not an acknowledged issue by Apple, so it would not have been included in support scripts
• Tier 2 support techs are given more flexibility than the initial Tier 1 reps that answer the phone, so if you can escalate to Tier 2 sometimes you can get "unofficial" information. I did on a different problem a couple of months ago
• Apple has thousands of support reps. Some are more highly skilled than others. And with that large a number, when a rep says they haven't heard of the problem before they might be telling the truth
• If a rep doesn't have specific instructions on a topic they will revert to "standard" troubleshooting steps, which is what you were told.

what if you've tried to restore it back to iOS 10 and is getting a message saying "the iPhone can't be found" what would I do then? I've had this phone for two years almost three. and haven't had any issues till now.

You have to download iOS 10.3.3 ipsw file from Apple server to your computer.

Then connect your iOS device to your computer.

Open iTunes app, select your device (iPhone or iPad).

Option-click the Restore button in iTunes and a standard file-selection dialog comes up allowing you to find your previously downloaded .ipsw file.

You lost all your personal data on device!

Run the recovery process.

Battery life has improved somewhat, apps still hanging. Phone has also become intermittently unresponsive. Pressing the home button will not wake up my phone. Lock button does nothing either. After pressing several times, waiting about 15 seconds later my phone will wake up. Pretty underhanded to make perfectly good older iPhones run like dog sh**
