I was wondering if iOS 10 will make the iPhone 6s slow

The non S models get slow with the iOS upgrades
 
Any older device could get "slow" with the next iteration of the OS, as newer features may require a more robust chipset. It's impossible to say what impact iOS 10 will have on older devices at this point as nothing is known about it. "Slow" is also subjective based on the individual user.

Well there's a lawsuit bc the iPhone 4 got slow

Every iPhone eventually get slow, even the S models.
But 5s is still pretty fast with iOS 9 and I expect 6s to work great with iOS 10.
 
All I can say is that my 6 runs perfectly on iOS 9.2. I very much doubt that iOS 10 will give the 6s any trouble. I don't think that the hardware demands for one generation of the iOS to the next increase that much.

And the previous law suits for this were thrown out of court. People can sue for anything, doesn't make them right. I have always updated to latest system on all my phones and have not experienced any slowdowns that I have noticed or bothered me.

Edit; Apple has just reported 75% of all iOS users are on 9.x. If there were such drastic slowdowns I have to believe there would be widespread panic reported in mass media, as that has to be in the hundreds of millions of users worldwide.

I will not address the people that think updating an OS does not slow your device. Instead, I will provide op useful information. As stated above, it will indeed slow your device down, if you notice those things. You are safe upgrading one OS version, with little (I still notice it) slow down, or at least so minimal that it is not painful to use afterward. Once you upgrade two versions past your original OS iteration, you're done; your phone will never be the same again.

Whether at that point one can argue that it is still "smooth" or "working well" is highly opinionated, but I have noticed this time and time again, and I never upgrade past one version, because it makes me want to stop using the device afterward.
 
The only thing I've noticed is that some of the S models were really overpowered relative to their non-S ancestors. For instance, 4S had 7x GPU power over 4, 5S brought in the 64bit era, 6S had the massive power increase over 6. 4 was barely faster than 3GS, 6 was barely faster than 5S, only the 5 managed to be twice as fast as its predecessor, but it had a bigger screen to deal with. Thus, a S model 2 OS iterations later should run more smoothly than a non-S model does. I think in the end, 3 OS iterations later, or even 4 if it makes it that far, neither series would last very long...

I think any device has the potential to get slow with updates. It can also depends on if hardware is failing or what apps are loaded. Also if it's a fresh install or OTA... Just too many variances.
 
My experience with my 6+ was that iOS9 was far more sluggish than iOS8 was.

What annoyed me the most was that Apple marketed iOS9 during a Keynote as a faster, smoother experience. It was anything but on the 6+.

I like my 6S+ and I'm seriously considering just leaving iOS 9.x on it and running it until the 7S to preserve the performance.
 
Based on how well the 5s still performs, and based on what a powerhouse the 6s phones are, in betting iOS 10 won't phase this year's hardware.

My experience, truthfully, is that even iOS 8 was far more sluggish in the 6+ than it should've been. Worst iPhone experience I've had to date.

Even iOS 8.x never ran that well on the 6+, as far animations and UI rendering went, and iOS 9.x was no better for sure. That problem was solved with the GPU and memory upgrade in the 6s+
Agreed. 6 Plus was a turd

Your information is just as anecdotal as anyone else's, and therefore no more or less useful.

OP is of a like mind, therefore he already believes and understands that newer iterations slow down your phone, which is why my opinion helps. To others, who don't believe that, it can be anecdotal.

Heed my words, it will.

The fact that your anecdote matches the OP's mindset doesn't make it less anecdotal or more valid than contrary opinions. How can you make statements like "Once you upgrade two versions past your original OS iteration, you're done; your phone will never be the same again" and just treat it like fact even though others have observed differently? Other observations simply don't count because they don't agree with the OP's arguable premise?

Correct.

As I have already stated, op was already of the opinion (before posting) that new iterations of iOS slow down devices. Giving an opinion that is contrary to that thought is not helpful for op, therefore only giving one that isn't, is.
 
Well, what would you expect? This year's computer is faster than last year's computer... Kinda obvious no?

When I had the iPhone 4, it was still usable on iOS6. Sure it's not perfectly smooth, but it is usable.
Currently my iPhone 5 is running 9.2 fine, to the point that I don't really notice it being significantly slower or not compared to iOS6.
I expect my 6S to be able to run iOS well for the next 3 or 4 years.

As for whether the OS slows down the phone, well, can't say I support that statement or not.

Yes, I think Apple can do a better job in releasing iOS with less bugs. Since iOS7, seems like Apple is getting sloppier and sloppier on their iOS release, prompting me to wait for at least a .0.1 or even .1 release before upgrading. In the past, it was safe enough to upgrade right away at .0 release. Now it it's Android, it's more excusable due to the myriad of hardware combinations out there. But that excuse does not run for Apple. Yeah they have more iDevices in the lineup than ever, but it's still a closed system where they are in control of the hardware. I expect Apple to release less buggy software than what they have done recently.

The solution is simple. If you are in the US, just get on board on Apple's iPhone upgrade program. There's no reason not to. You get the latest iPhone every year, unlocked, including Applecare+, for a low monthly fee. I wish Apple roll that program everywhere. It will definitely kill the carriers' greedy contract model, and force them to compete on service.

One other way is simply to be smart on your purchases, and history pushed me to be on the S cycle. The non-S cycle will introduce new design, where there are risks for unforeseeable defects. The S cycle is a safer bet on that alone.
