9.3.2 is a POS on my 5S. I have Sprint as my carrier. Can I "downgrade" from 9 to 8 if I get the correct .ipsw? Not looking to jailbreak unless I have too.

The firmwares in ipsw.me show GSM and Global. I don't know which one I need. I suck at this.
 
What problems are you having?

I have an iphone 5s with 9.3.2 and I have not noticed any problems.
 
Not sure if you can do the downgrade without jailbreaking as they typical stop older versions from being re-installed (or that's my understanding).
What is the base version on the phone, you might be able to wipe the phone and go back to whatever came with it. That's what I've done in the past.

For me, I have wifi issues since upgrading to iOS 9. Have to disconnect and reconnect sometimes multiple times per day. Tried the fixes I've found online and talked to Apple support. They're not sure what the issue is.

As far as the GSM vs. Global goes, here's the info:

iPhone GSM Model Numbers:

iPhone 5s — A1533 model
iPhone 5c — A1532 model
iPhone 5 — A1428 model

iPhone Global (CDMA) Model Numbers:

iPhone 5s — A1453 model
iPhone 5c — A1456 model
iPhone 5 — A1429 model
 
Specifically, Apple stops signing older versions of iOS not too long after newer versions show up. It's mainly for security (since someone could send you a bogus older version).

Have you tried just wiping the phone clean and setting it up as a 'new' phone? That could eliminate any problem settings or apps.
 
Well it's slow. When switching apps they will hang on the screen for a second then switch. Also the battery indicator is either wrong, or the battery is crap. it will jump from 30% to 15% on a regular basis.
 
Back up your data to iCloud and set the phone up fresh. You can't roll back to 8.x but refreshing the phone will clear some settings that can only be cleaned out with a full wipe. It's not unusual for an iPhone to accrue "cruft" after being repeatedly updated between major versions without a clean wipe in between. It's the main reason the first thing the Genius Bar will help you do is reset the phone if you complain to them about issues like this. It really does help, especially if you've updated from 8 -> 9 without a clean wipe in between or, worse, from 7 -> 8 -> 9 without wiping.
 
You can't downgrade it unless you have a backup with that IOS. They don't want us to downgrade so that we are forced to change the devices after 2-3 IOS versions because it is getting too slow.

You cannot downgrade, even with a backup. There is no known exploit for downgrading a 5S (or any other 64bit iOS device) at this time.
 
Bummer all around. I did a restore though, and that seemed to have fixed most of my issues. I should have thought of that first. Thanks.

Nah, it's not a conspiracy. You could argue that Apple wants to minimize the need to support older versions, but it's not using this to arbitrarily push you toward a new phone. If it wanted to do that, it'd do what many Android vendors do: purposefully stop updating your phone after a year or so.
 
It's already been said but downgrading is not possible.

How old is the phone? It's pretty likely that you're battery is showing it's age and could use replacing. As for your performance problems, there are many options you can disable that will improve performance. I have a 5S as a work phone running 9.3.2 and after disabling ALOT of options the performance is great and I get awesome battery life compared to my iPhone 6 personal phone.
 
I'm on a 5s now as my primary and I don't have any what I would call slow downs or issues with it.

It's still quite quick. Opening for most apps is instantaneous. Loading of said apps is generally 1-2 seconds. I have a 4s to compare and there is a world of difference.
 
The fact a three generation old ( soon to be 4) phone can work so well is a testament to the efficiencies apple puts into the software and hardware. Can anyone name an android phone that is still good after 3 years?
 
I concur with some of the comments here. I also have a 5s and disabled a lot of features (e.g., background app refresh, apple music, etc.). Although, I'm running iOS 9.3.1 and never want to upgrade to 9.4 or higher. Sounds like a wipe/rebuild would be helpful. Perhaps try 9.3.1, or a fresh copy of 9.3.2?

My Samsung s4. I felt that phone worked as well today as it did when we bought around the time it released. I only upgraded to the 6P because the wifes s4 was having hardware issues and we both got new phones.

I do agree, however, that Apple devices often work many generations later and just as well as they used to. My daughter's 4s STILL received updates to ios9, although we haven't installed them.
