What you are experiencing is perfectly normal due to the mess of what iOS 11 is, everything is just sluggish and feels forced. I’m confident iOS 12 is going to solve most of it after all it did make my iPhone 7 Plus feel like iOS 10.3.3 on iOS 12 beta.

I hate when people suggest this. That defeats the purpose of a backup if u constantly set up as new.
How? A backup is important because it retains a copy of valuable data. Nothing about a backup suggests that it must be restored. There are other avenues to getting your photos back from the backup on a new device. If restoring your data means that it impacts the performance, then it is the fault of Apple.
 
Hi
I owned iPhone 8 and decided to upgrade to the X (256 gb, black)
I notice that the performance is worse- sluggish animation, safari sluggish etc.
Why is that? Are we going to see improvement on iOS 12?
To be honest, I’m disappointed.
Thinking about buying 8 again
Defective unit. Show the issue to the genius, if they cant fix it, they will replace it
 
I did restore my old data.
If I will set it as new phone, I will lose all of my data..I rather keep my photos and contacts...

Your contacts are linked with icloud. just logging in with apple id will restore the contacts. you can save your photos and sync them later. it is better to set it up as new and then add app one by one through fast wifi

You can try both on the same device.

If you are experiencing issues. Create your most up to date backup. Then erase all settings, etc. Set up as new phone... try it out on a few things you do, see the performance difference if any.
Then you can repeat, erase all settings etc and restore from the backup and try performance again.

This will give you a direct result of, is my phone itself and fresh software the issue or is my backup and previous settings causing the issue.
This give you more data moving forward to try and fix the problem.

Then you have to take that data and actively take steps to fix the data from that point or..... don't. But then it is on you and you have to weigh out where your value is.

Restores CAN impact performance. How much? There are many factors, some from zero performance hit to a major hit.
So testing both scenarios give you a better representation on the exact piece of hardware. You just have to put in the time to either A. do it yourself or B. have someone else do it.
The only other option is to do nothing but then the result is to get nothing.
 
This is such a silly idea and is only for the geekiest of geeks. To literally lose everything they have and start new every time, when one of the main reasons for getting an Apple product is to transfer this stuff seamlessly.

Restoring your backup of potential bloat and crap is the easy way of doing things, not the best way if you value performance. I've experimented a lot with this and every device I restore never performs as crisply as a device configured 'as new'. The data transfer/restore to new device includes caches of data which is the cause of the slowdown. An 'as new' device has no cache trawl through hence no lag, performance issues, animation slowdowns etc.

Of course everyone's data is different, so it's not typical of every transfer/restore scenario. However, I will always opt for a 'as new' set-up on iOS and always a clean install for each major macOS release.
 
Go back to the 8 then. To be completely honest the 8 is better than the X, not just performance wise either.

I did Geekbench to the X - SC 4240 MC 10437
Fine for the A11...
Is there anything else that I might miss?
 
Did you set your iPhone X up as new, or did you restore your old data onto it? Restores/importing from backups always bog down a phones performance. If you want the best performance, always set-up 'as new'.
What is the point of a backup if it isn't to restore onto another device if something happens to the original device?

As do most people I know and they don't have an issue with it.

If an iCloud backup wasn't supposed to be restored to a new iPhone I wouldn't be paying for iCloud storage.

While that is true it is unacceptable to tell someone not to restore from their previous backup. If there is an issue with restoring to a new device Apple needs to resolve it.

You’re saying your being honest, but that’s just your opinion, not a state of fact. That’s perfectly fine that you believe that, but that doesn’t mean your claim _is_fact either. Both phones are supporting different types of biometric security, form factor, display panels, camera technology, etc. In terms of technology, the X is leading in that category, but the user decides which phone experience is ‘better.’
 
What bloat and rubbish specifically is actually coming with the backup?

I’ve always wondered this. I’ve always restored with each new iPhone I’ve had and have had no problems with performance or storage.
Same. Apart from some minimal lag while it’s pulling everything from cloud but this doesn’t last long.

I think you should make a distinction between who should not say it and who should. I am not Apple. I don't speak on behalf of Apple and I don't think the person before me spoke on Apple's behalf either. We as Apple fans can suggest options to explore that might be favourable to someone who needs the help. I don't see anything wrong with that.

Apple does need to resolve the performance issue for sure, but it isn't them telling their users to avoid the restoration feature.

I had Apple tell me not to restore my iPhone from a backup in the past so they are telling their users to avoid the restoration feature. But you're right they do need to resolve the performance issue.
 
I’m on the iOS 12 beta and the iPhone X that I have is running so much better. I actually enjoy using the phone now. Everything is faster and smoother. The X felt like a beta device because of iOS 11.
I agree here. I am hoping that iOS 12 is more refined. Right now this whole phone feels like a Beta. Just take a look at the stupid and ridiculous YouTube app getting stuck sideways etc.

No one is telling anyone to not restore from backup. We are simply advising that if you want the best performance, set your device up 'as new'. I don't care what people do either way, but I do agree that Apple needs to sort it out. Restoring data without bringing caches across would go some way to fixing it.

Did anyone bother asking the OP how long after setup he/she was seeing performance issues? If it’s only been a few minutes from setting up the phone of course it’s going to be slower as it indexes and continues pulling data down.

Yes but unfortunately this is how technology works. Sometimes there are bugs or differences in code between the two devices that cause unintentional performance issues when setting up the a new device with a previous device's backup image. I see this a lot with my work in analytics.

Typically setting up from a backup is ideal, but if there are issues like in this case then it is worth the user trying to setting up the device as a brand new device. If the issues disappear, then the backup image is the issue, if the issues still continue then the device is faulty and needs replacement.

That's a valid point.

How long has it been since setup that you’re experiencing the sluggishness?
 
You'd better to clean junk files, caches, crash files, browsing history or all temp files on iPhone X/8/8 Plus regularly.

iPhone X Cleaner (Mac/Windows) is a data cleaner program, which also compatible with iPhone 8 on the market. It allows users to remove all unnecessary or hidden files from iPhone 8 and speed up your device soon. And the iPhone 8 Data Cleaner software also can help you find out crash, junk, cookies or temp files on iPhone 8 and clean them with 1 simple click.
