iOS 11 incredibly slow on iPhone 7 Plus

This is nuts.

I also had some repair done on my iPhone 7 128 GB by another company than Apple. Phone works perfect in iOS 10.3.3.

Just called Apple to ask what I was supposed to do and referered that Apple Support had mentioned hardware issues to some of you guys. I was told that since iOS 10.3.3 worked perfectly, it wasn't a hardware problem!

So my best chance would be to wait for yet another update and see if that helped anything. This isn't really an option as my waranty (if it's still any good - Apple told me it was) is valid until the 3rd of October.

I could also update to iOS 11 and call back from another phone and they would check to see if they could figure out the problem.

Or I could visit an authorized apple dealer/repairshop with the phone with iOS11 (we don't have any Apple Stores in Denmark), but they would probably just say, that it wasn't a hardware problem because the phone worked in iOS10.3.3 and then they couldn't/wouldn't do anything.

So later today, I'll call Apple again from another phone and see. Next thing would be to visit an authorized repairshop. If this doesn't resolve anything, then I either need to wait for another update or buy a new phone 😢

Unfortunately, that's not true.

New versions of iOS can use the hardware in slightly different ways such that something that used to work in 10.3.3 will no longer function in iOS 11 - sort of like if you have a broken lock on the back door of a house, you won't know until you stop coming in the front door.

I have repeated the recommendation to go to an Apple Store so many times I've lost count. I've also lost count of the number of individuals with problems that absolutely refuse to follow my recommendation because they KNOW what the problem is and they KNOW that nothing is to be gained by going to the Apple Store.

Thanks for posting results!

They must have heard. There’s a new update 11.0.3 that’s states the issues with the iPhone 7 and 7plus and also about those repair screen on multiple models.

Now is it going to fix the issues or not ???

Does anyone see any improvement since the iOS 11.0.3 update ?

My phone had the exact same symptoms as yours, but unfortunately I just sold it, so I can't test 11.0.3 to confirm it resolves the issues. Based on the content of 11.0.3 though, I'd bet money this is the fix we've been waiting for.

And iOS 11.0.1 out now.

I'll give it a go later and see if that fixed anything.

my screen was replaced by a third party

If he answers you, I expect that he'll advise you to take the phone to an Apple Store for evaluation and resolution.

Your problems sound different Hedge Dee but there are other threads on the board with high battery drain. Apparently updating to 11.0.1 helps.

Have you tried going to an Apple Store? If not, you haven’t tried “everything.”

I have the exact same thing. No sounds, no sound during calls, no vibration, horrible delay before any app opens. Useless phone. This is absurd. I restored and powerd off/on a million times. Nothing helps. This is ridiculous.

Alright fellas, So I had my phone call with apple last night, they basically have no idea what is going on so they don't seem to have put all of the reports together yet.

They talked me through the possibility of doing a fresh install of iOS 11 and setting up as a new phone, I told them I have done that 4 times already to no avail.

They took a copy of my diagnostics file and told me that the engineers were going to look at it and get back to me when they had any updates, right now I'm torn between sticking with iOS 11 and letting the engineers work so that hopefully they can develop a fix, or rolling back to 10.3.3 so that I can actually use my phone.

Anyway apologies for the completely unhelpful update, apple support handled the situation really well but unfortunately they don't have a clue why it is happening considering my diagnostic file showed no fails when they scanned it.

Mine lagged for the first hour or so after I finished the update. It appeared to be downloading and updating a lot of stuff in the background. Since then it's been perfect.

That makes sense. I didn't notice it myself because I didn't use it much after updating.
