iPhone 8 slow performance.

Well I wasn’t quite surprised seeing my iPhone 8 slow, but it seems like it is way more slower in performance as expected. I’m pretty sure the performance problem is due the the iOS. Is any one still feeling the same poor performance after updating it to iOS 11.2.2?

iPhone 8, iOS 11.2.2

What have you done to solve your iPhone 8S issues?

What 8S storage size model do you own and how much free data storage space is left on this iPhone?


Have any of you tried a hard reset of your iPhone 6/6S by holding down both the Home and sleep/wake buttons until your iPhone goes to black and restarts with Apple logo, then release the buttons?


iDevices need to maintain, at least, 2-3 GBs, OR GREATER, of free data storage space.


In Settings App, Battery, check to see if any apps/processes are eating up your battery.


In Settings app, General settings panel, turn OFF Background App Refresh for any apps you feel do not need constant data updating/Internet updating in the background when not using the an app OR turn OFF Background App Refresh entirely/globally for the entire device.


Do the same in the Settings app under Notifications.Turn off notifications for apps you do not think you need notifications for and/or edit the different ways you receive notifications to help with performance by not always using all the notification methods together.


In Settings app under Mail, you may want to set a longer fetch time or set your iOS Mail app to only manually fetch your mail ONLY when you launch the iOS Mail app.


In Settings app, under General settings, Reset panel, at the right bottom of the list, Reset All Settings.


In Settings app (NOT from the iOS Control Panel) turn OFF Bluetooth when not using any Bluetooth devices.


Also, in general, if you want a faster IDevice, on all of my iDevices, I turn off most of the iOS motion graphics eye candy, by simply turning ON Reduce Motion in Settings app, General, Accessibilty settings.


Make sure you aren't running scads and scads ( 20 to 50 OR MORE ) of background apps in the iOS 11 Control Panel/App Switcher.

If you are, you need to quit the bulk of these background running apps by tap and hold a finger on an app window in the switcher and slide your finger upwards to quit an app. You should be able to use more than one finger to quit more than one app window simultaneously.


Also, make sure you don’t have scads and scads ( 20 OR MORE ) of active website tabs running in the web browser.

If you do, greatly reduce the amount of active website tabs your web browser.


Some minority of user have been turning ON and leaving ON iCloud backups continuously backing up on a constant and daily basis.

If you are one of these users, in Settings App, tap your Apple ID, then tap iCloud, then find iCloud backup and turn off iCloud backup and only turn this on to do daily backups either when you are not using your iPhone for a prolonged period of time (like when you are sleeping), then turn iCloud backups OFF when actually using your iPhone.


OR


Only perform your backups on a lesser time schedule.( like twice a week, once a week, once every two weeks, once a month, etc.).


Any large amount of background running apps or active processes that have to constantly go out to the Web to fetch data ALL THE TIME is going to slow down ANY iDevice.

I guess what's frustrating to me is ...


I have not added any extra data or apps on this new phone.

In fact, I have deleted apps and things I really don't use when I got this new phone.


And my phone 7 plus was way faster.


I really can't delete the apps I have on this phone ... I even turn off "refresh background" ... the apps are not open if I'm not using them.


Maybe the next thing is to remove my photos completely off my phone into an external drive, I don't know.


Just really regret buying this new phone, if I could get my old phone back I would.


I REALLY appreciate all your help and advice -- and I'll try your suggestions as well. 🙂

Since the 12.0.1 upgrade, I too am having a horrible time with my iPhone8. The phone shuts down for no reason and it takes me 10 minutes to boot it up. Not cool when you are using an electronic boarding pass to get on a plan. The lag time has increased; photos take forever to load, and I've had a whole other sundry of issues. I have plenty of space available and yes I've done Hard resets. To date, about 50 of them. Nothing gets better. Seems like a software issue which as usual, Apple will wait forever to fix.


Time to go Samsung. What a disappointment.

It's ABSURD how iPhone8 Plus is slow!!! This supposed to be a BETTER and FASTER phone ... has DOUBLE the memory from my iPhone 7 Plus ... and yet, here we are researching how to make this *&%@ing phone to function without freezing or taking forever to download anything.


To update my information from my old IPhone 7plus, I spent over 1 hour at Apple Store.

Got tired of it ... decided to go home ... "maybe" the WiFi was the issue, I thought.

Nope.

It took me 3 HOURS waiting for ALL the apps to upload at home.


Got tired of waiting ... I had delete ALL my apps (literally!!!) to finish the upload of my simple date to this new iPhone.

Then ... I uploaded 2 apps at a time (afraid my phone would freeze uploading the apps again).


Now ... If I need to send an email with a 30 secs video .... my email says "attachment too long".

Huh?
On my iPhone 7 Plus ... I've emailed videos of 5 mins or more all the time!!!

And this phone can't email a 30 sec video??


Hard not to think this new phone is a piece of crap and Apple is banking (as usual) loads of money. I swear this feels like a refurbished iPhone.


My suggestion here is for all of us customers who are stuck with this piece of crap to unit against Apple and ask for a public explanation.


I'm a huge Apple fan.

Not this time.

So ... Yes, I'm very upset and frustrated.

I get all that.


Maybe I didn't make myself clear ... I JUST bought the phone!


NO one should go through ANY hassle dealing with the worst slow iPhone I have ever bought.


Mind you ... this phone has the most Memory than any phone I used in the past ... 256GB!!!


Sorry ... there is no excuse for any of us to have to delete anything from the phone when I just DOUBLE the capacity from my previous phone.

I am ver disappointed with my new iphone8S. It’s very slow and is glitching. Apps shut down while in midstream. I have an iphone6S which is working much faster and both are on identical plans. My iPhone 6S has more apps and is nearly full but the 8S is brand new and has almost no apps. What is going on? I think I will have to give it back. I don’t care about wireless charging. I had hoped it would be faster and take better pictures

My iPhone 8 has been working fine for a few months. Lately. It’s started to get quite hot especially when I’m running maps, plus sometimes safari just freezes and you have to reset the phone as the touchscreen doesn’t respond. It’s really frustrating as I have tried all the usual steps. Anyone got any advice. Plus my iCloud keeps asking me for my password
