I've owned this iPhone 6+ since it was released in 2014. I haven't replaced my battery but I'm wondering if I should update my iOS to iOS 11 its currently running iOS 10. My concern is whether or not the phone will begin to slow down as right now its moving pretty fast.

From what I've seen around the forums, older devices tend to be a bit more buggy on iOS 11. I only have a few sporadic issues on my iPhone X. iOS 12 is supposed to be announced today which is rumored to to have overhauled performance and stability. Considering the iPhone 5s is supported on iOS 11, it's pretty safe to say the 6 will be supported on iOS 12. You might wait and see if users on older devices are seeing improvements on iOS 12—especially a month after official release this autumn—and if so upgrade to that.

Running the latest IOS 11 on my 6s + and that has no issues to date.

You will regret it if you do it.

iOS 12 has significant performance increases for devices up to the iPhone 6. So possibly worth waiting for developer feedback on the beta.

Absolutely, unequivocally, no. No way. 6+ is a dog.
I think that’s debatable. Because some have posted when they had the upgraded their battery from the replacement program and their software, they noticed some decent improvements with productivity and efficiency with the iPhone 6/Plus model.

Fair.

I can only go off of how terrible my 6+ handled iOS 10.

I would keep it on 10.3.3 if I were you.

11 is not bad, but I would not have been happy with it on my older devices. I would likely consider upgrading it to iOS 12 in the future...assuming that it is as good as they say that it's going to be.

I kept my launch day 6 plus right up until the iPhone X came out. I still own it.

It’s running 11.4 now and it lags a little but it is completely usable.

I only update my stuff if there is a feature that I must have. I have six sense about malware blah-blah and not afraid of them. To me, no updates are bug-free and newest may not be the greatest. i.e.: Battery-slowdown-gate.

Realistically the newer updates are what would allow you to disable the performance throttling if you run into it due to a battery that isn't in good condition.

6s is a major upgrade from a 6. My 6s runs fine on iOS 11. The 6 will probably take a noticable performance hit.

My SE runs pretty good on 11. The SE has the internals of the 6s. My 6 took a hit though when I updated it to iOS 11. I am hoping iOS 12 makes it a little faster.

I’d wait until 12. iOS 11 has not been a great release for anyone other than X and 8 series owners.

Let’s put it this way - if I could get the last stable release of 10 back on my iPhone 7, I absolutely would.

There’s no massive reasons to update to 11, unless you know of a feature that’s an absolute must have for you.

My 5s ran iOS 9 like a dog. I don't think a 6 with iOS 10 would be much better. And iOS 11 is much worse. At least wait for iOS 12.

Every full number update to iOS (or MacOs for that matter) since forever has been slower than the previous version. That trend will never stop and you can take it to the bank. Apple does. It's the only thing really that drives hardware upgrades.

There used to be an old Axim stating that there were two certainties in life: death and taxes. Well now there's three - slower OS upgrades.

And yet here are people who even have the same overall opinion who have admitted that going from iOS 9 to 10 was an improvement for them, for example. There are certainly quite a few who are already finding the first beta of iOS 12 to be better (and this isn't just a beta but the first one too).

Writing from experience:

I didn't upgrade my mom's iPhone 6 from 10.3.3 for the longest time because I knew just how slow it would get, seeing my iPad just hit a wall after I did.

But one day it caught her by surprise and auto updated to iOS 11. Instantly the performance and battery was going haywire- one phone call and battery would go from 50% to 7%, lag, and generally be a liability to use.

Best option I had was to change the battery as it had some 868 cycles and showed battery health of 78% (shown under the iOS 11 battery health beta settings).

So got that done through the relatively inexpensive battery replacement program at Apple. Honestly, the best $30 I've ever spent cause the thing runs like a charm now! Got atleast another year left in it which is impressive for an almost 4 year old phone!

Hope this helps.

Tl;dr
Upgrade to iOS 11 and get the battery replaced through Apple's battery replacement program

If you like punishing yourself, update to iOS 11. It's that bad.
