iOS 8 on iPhone 5?

[clukas]

Ok, take the comments above with a pinch of salt. As often with new iOS upgrades people experience perceptual slow down (i.e. they think its slower, because its what their mind wants them to think). I am not saying that iOS upgrades have not slowed down previous devices (iOS 7 on a iPhone 4 for example etc.) however lets look at this logically. There is no significant new graphics engine powering iOS 8 so from that perspective things should be ok. Healthbook, extensions etc. do not require significant performance to operate, so that should also be ok. I have not noticed any significant performance difference on my iPhone 5 and have been running the GM since day 1. If you don't over obsess over performance, you will not notice that its even running iOS 8.

Glitsy, slow, not smooth, not light.
Typing, scrolling, transitions. It is a bad update for me.

I did a restore. And an install. But have put a backup back. Because, I am still an iPhone user. I am not a new user. So I want the back up restored.

How is your scrolling?
Specially in a Mail Message or in Safari on a page?

Curious, because with scrolling there is no butter and its stuttering.

Scrolling is smooth on my iPhone 5.

Exactly the same expectations Ars Technica had (i.e. there shouldn't be a slow down) before they actually made some measurements and found the 4S was notably slower in opening apps and doing UI animations. If it's slower on the 4S it's almost certainly lower on the 5, it just won't be as noticeable.

I've had a generally ok experience on my iPhone 5 with iOS 8. However one thing I do notice a lot more, particularly on the MacRumors main page, is that Safari takes a lot longer to draw web pages. I'll scroll down and there'll be a blank screen for a second or two before it fills in.

It works just fine on my iPhone 5... No lag whatsoever...

It's so weird seeing such vast difference in user experience on the same hardware after the same OS update.

Everything on my 5 is buttery smooth, and I just tested scrolling in both Mail (picked one long message to test it) and Safari (tested numerous sites including this one) and no stuttering whatsoever. And I have to say I'm pretty sensitive to visual stuttering, I experienced it when I updated my iPad 3rd Gen to iOS 7. No such issues on my iPhone 5 with iOS8 (going on 12 hours of use now). FWIW, I did the update as OTA (the download was around 900MB).

I will be updating my wife's iPhone 5 later today and will report back if it's any different than mine.

..900mb?!?!?!?!

Yep, it sure was. It took just over an hour to complete too. I read here (on another thread) that for the iPhone 5S the OTA update size was 1.1GB.

That is weird indeed. And I had never an issue with it. I read some other people experience this as well. So now this could have to do something with text size/ accessibility settings. I have all the new shiny transparent things turned off. And I get seasick of the Motion.

Mine is a A1429 model (btw)

I want that :O

 

[Fuchal]

Everything is great and seems just as fast if not faster on my iPhone 5. (for once)

 

[macenied]

No problem so far with iOS 8.0 on my iPhone 5. Download size ( iTunes ) was 1.1 GB.

 

[mantan]

I'd wait. There isn't enough new features in iOS8 to make it a 'need to have' and like most .0 upgrades, it's not as polished as it's going to be.

There are enough reports of lag to make you kick yourself if you install it have poor results.

7.1+ works great on the 5. I'd leave well enough alone. We downloaded 8 on one phone in my house. And after the results on that - everybody else decided to stick with 7.12.

There is definitely an issue with the scrolling on my iPhone 5. And it has nothing to do with what you say in your comment. Of course there is more to explore in iOS 8. You can do more. So older devices experiences would be different. But the scrolling/ smooth scrolling just doesn't work. That is not an experience. That is a fact. (Tested and concluded).

True. However, this thread is how the iPhone 5 performs with iOS 8. If you are experiencing issues, you need to sort them out anways, thus many report already no problems so far. I can feel no performance decrease, althogh my feeling is certainly no benchmark .

Same here, no problem with scrolling. It's smooth and fast.

Ok. I'm just trying to determine why there would be a slow down in scrolling. I doubt the code changed much. There are hundreds of factors affecting a phones performance, one of which could be a poorly designed app your using which is using up processing power in the background. Scrolling is as butter smooth on my iPhone 5 as it was on iOS7. So I wonder whether this is a rather isolated problem affecting a fraction of iPhones or a broader problem.

 

[lambertjohn]

No problems on my iPhone 5. Runs fine. No lag that I notice.

 

[D.T.]

What does iOS8 run like on the ip5? I have it downloaded and am just ready to hit install but am hearing some bad reports about slowness.

Running outstanding on my 32GB iP5, installed as an OTA update over iOS7.

New features working great, standard apps running as expected, core 3rd party apps running just fine.

Even Dropbox is Constantly Crashing

Did you notice on the last update, the notes mentioned something about installing it before updating to iOS8[?] FWIW, I didn’t, but I’m also not having any issues.

Sounds like maybe there’s something potentially janky with the last update, I’d un/re-install.

 

[cpnotebook80]

So here is an update to earlier

I charged the ip5 fully last nite. I checked it at 11:15pm and it said 100%
Woke up this morning and it was at 99% with few emails that came in and 2 texts which for some reason came in in the morning when it was suppose to the night before.

Anyways, off to work and and now its 10am. The battery is down to 80% after bit or reading emails and texting this morning.

I notice that the battery percentage jumps around almost like a glitch but i'm sure all these small bugs will be fixed in later updates.

Honestly, I have no problem with it. The only problem I had was with slight typing lag on my iPad mini Retina, which was fixed after disabling multitouch gestures to go back to the home screen and switch between apps.

 

[imagineadam]

I'm very hesitant to install to my iphone 5 because I'm jailbroken on 7.1.2 and it's buttery smooth and works great and I love my themes. I installed it on my iPad 4 and it's laggy and dropping frames in the animations and taking about a half second to launch apps after u touch them.

Anyways my question is, are you guys noticing less apps being suspended in the background in ios 8 or about the same? I know if I have facebook open (in ios 7.1.2) it eats up a lot of ram over time and usually all but 3 or 4 of my suspended apps hang around. However if I keep FB killed I can keep suspended 10-15 apps. How is your experience with suspended apps in ios 8 on your iphone 5?

 

[macenied]

No iPad 4 performance issues here. Actually typing on this iPad now, no noticeable difference to iOS 7.1.2. It's fast.

 

[iPhil]

On my 5 while on 7 by 12 pm est after full charge i'd be 75% or so after FB for awhile / news sites only no video via youtube.. On 8 now i'm @ 88% doing exact same thing.. thats on like 2.5 hrs to 3 hrs "light" use...

So 8 is better battery for me in my short use of 8 so far ..

 

[zjazz]

Same experience here. Runs, but it's slower than iOS 7, not WAY slower, but I notice it.

In the very beginning I thought it is the same as 7 but now that I used it a bit it seems a tad slower....maybe I need a clean install because I did it over my 7.

 

[lamerica80]

Its definitely slowing the system down, i see a lag when typing and when switching to landscape mode, for example.

 

[T-Will]

The only lagginess I've noticed is mainly opening Spotlight search with a 3rd-party keyboard (Swype).

I'm anticipating Apple will optimize performance going forward now that new features are in place.

YMMV, but in my experience a clean install has never yielded in any benefits over an upgrade on my devices. It's a heavier OS, that's just the reality. All the talk of how Apple are the optimization gods and they'll make every new OS not only do more, but run better than the last, even on older devices is just fanboy speak.
