iPhone iOS 11 on a 5S. Just don’t do it!

There is a theory that iOS 11 is specially tweaked to work well on the X/8/7, say, but not for the 5S. How would we know that really?

What if, contrary to the above, iOS 11 is poorly optimised for *all* devices, but still runs OK on the newer ones because their hardware is super-powerful?

The A11 Bionic is indeed impressive. Its half the power of the 7700K powering my state of the art gaming PC and Apple's done a outstanding job here. But it doesn't take a 7700k to run Windows 10 without stuttering nor should it take an A11 Bionic to run iOS splendidly. If it does take disabling features so that a CPU like the A10 Fusion can't handle it Apple's optimisating is very bad as I consider even the A10 an outstanding CPU. But even then I would have no qualms if Apple disabled the features which stress the A10 and the battery but they don't.

Maybe it’s a problem with the actual battery? When did you get the phone? 4 years could put wear on it.

I see people pushing the idea of battery degradation coinciding with upgrading to iOS 11 in multiple threads. Can battery degradation be so sudden? I would imagine it should be much more gradual.

In my case, replacing the battery on my 6s did not help at all with battery drain on iOS 11.

I wish people would be more careful when discussing unverified hypotheses with no evidence to support them. As a result of such discussions, some owners of older phones would be paying for battery replacements hoping to improve their battery life, when in fact it does little or nothing.

Luckily for me, I did not have to pay for the new battery on my phone, as it was still under AppleCare

I am one of the few that would have gone back to 9 over 10. That’s where the text contact problem started and freezing in phone app started. It ‘still’ says just the phone number or ‘maybe...whoever’ when I get a text, instead of the name that’s in the contacts. And a name that’s always been there that showed as their name in notification and not this guess work in 10 and 11. It’s never fixed that on this phone. Also apps that are open that you want to go back to quickly all restart. Say, a message on Twitter, every time I get the blue screen and bird that I have to wait for opening instead of just still being open on the messages I left seconds before. So it seems that 11 may be working harder and draining quicker

So now you’re telling me how my devices are and what my opinion should be of them? Exactly why these convos go on endlessly.

No I am telling you my conclusion on that device because I owned an iPad Mini 1.

I don’t think I’m ever updating my SE from 10.2 even with a jailbreak

But how is ios 11 with the small screen?

Are all the huge headers ridiculous and does this OS ruin the 4” form?
 
@thadoggfather,

Iphone 5S user here:

I am pleasantly surprised by the changes to the interface, and in a positive way. I was worried I would NOT like the changes, but the larger, or just heavier weighted, font being used in some default locations such as in Siri and it places like the reminders list and the phone call record gave me a "hey! I like it" feeling when I initially went to use those features after the upgrade. I generally DO NOT like change at all, but I have found nothing yet that makes me want to go back.... from a U/I or U/I experience perspective.

I will post more later about my overall IOS 11 upgrade experience, FWIW.

One thing is for sure: I am hoping the slightly bolder fonts and/or the white backgrounds that seem to be more prevalent will help me with my one biggest issue with the 5S: I have a really hard time using/seeing the writing on the screen when I am not wearing my bifocals or my eyes are really tired. Next time I'm not wearing my bifocals (i.e.... wearing my contact lenses) I will find out!

And why have they changed the 'add picture' in email replies. It must be more used than what they've put before it now. Just leave stuff alone that works and has been same since beginning. There was nothing wrong with where that 'add attach" was before.
 
iOS 11 is so bad on the 5S. I upgraded to an 8 Plus a couple weeks ago, so I don't know how it is with 11.2, but when I was still using my 5S, the performance was greatly impacted and battery life was much worse. On iOS 10, I would still have 15-20% battery when I got home, after I upgraded, it would almost always be dead.

I did do the 11.2 update on the 5S, and it seems to be much better on standby after that (before, the battery would drain pretty fast in standby mode). Hopefully Apple figures out what's causing this stuff and fixes it ASAP. The battery issues seem more like a bug than a lack of optimization for the 5S. I'm not sure they can really fix the performance, but at least fix the power consumption.

I've given up with it. Also will have to upgrade phone now. Mission accomplished Apple. They've done same with my MacBook Pro. Also redundant without updates now because it can't handle the updated OS. And iTunes and Safari etc don't work anymore with the OS. I'd never go back to Windows and lucky for Apple they know most of us won't.

They're on a roll with changing what works well with things that make less sense.

iPhone 5 32bit is the ONLY iPhone that DIDN'T Get slower or still usable for 5 years from iOS 6 to iOS 10. In some Areas like App store and Camera Loading, and saffari the iOS 10 is faster than iOS 6-9

Right now, iPhone 5S on iOS 11 is just like iPhone 4S on iOS 9. Expect, what to expect huge battery drain even after replacement due to A7 not being power efficient like newer iPhone. Ultra slow, everywhere but still usable. if you're patient.

While the iPhone 6 on iOS 11 is just like 4S on iOS 8 A little bit better in terms of performance, but the battery is still kinda worst than it was on 10.

while the 6S on 11 is like 4s on iOS 7 which has some stutters and so on..and much better than 5S in terms of performance.
