Interesting. I had much better results all the way around with 9.1 than the 9.0PB on an Air 2. Are you seeing a difference between battery life on 9.0 public release vs 9.1 PB?

Not yet. Battery is definitely stable overall like it was on 8.4.1

I knew it would be laggy. I think I'll keep my iPhone 5 nice and snappy for another year without updating to iOS 9.

Everything runs great except Quick Reply from a banner when a message is received. It's like take-twenty-seconds slow. It's completely unusable. Been that way since PB3 and still sucks on the official release.

Even though some Apple fans swore it wasn't.

Going to try a fresh install now to see if its any less laggy on my iPhone 6.

Getting the iPad 1 form iOS 4.3 to iOS 5 vibe. Not as unusable but pretty damn annoying.

Useable? Yes

Does it feel like a blazing fast and modern OS on an iPhone that was just released a year ago? Nope.

Seems like iOS 9 was made for the newest iPhones/iPads which is disappointing because in the past, it took about 2 cycles before devices would seen noticeable slowness.


I actually like it a lot! It's working perfectly on my iPad Air 2 and iPhone 5s. I'm actually surprised how good iOS 9 is on the 5s

So far iOS 9 has run geat on my iPhone 6 Plus and it has even fixed a few bugs one is where the phone would run of memory and crash all running apps and the spring board and restart the phone and a another issue is I use streaming apps for music when they would stop playing for a few secounds due to the handoff from wifi to LTE but now with iOS 9 its all smooth. Also I have been running the betas on my iPad air 2 from when the public betas were out and never had a issue at all.

Transmissions are really laggy. It doesnt matter if OTA or fresh, both were same. But it is not something unusable, just not as smooth.

Mail is much slower now...why?

Luckily you can turn off the new lower case keyboard. That was annoying.

Overall, nothin really that new. It does seem more sluggish IMO on my 6 Plus. iPad Air 2 seems same.

I just downgraded to 8.4.1 again and MAN is it SMOOOOOOOTH. It's copying all of my music (plus indexing probably) and it's smooth as silk everywhere. Swiping, launching apps, control center, multitasking... everything responds super quickly. It's really really nice.

Ah, it's good to be back. 9 doesn't really have a lot of features anyways. Meh. Perhaps I'll stick it out on 8.4.1 until a worthy iOS 9 update comes out.

Exactly. Once you downgrade to a fresh install of 8.4.1, 9.0 is no longer "smooth". 8.4.1 is a much, much more polished released. It's scary to think that other people think 9.0 is on par with 8.4.1. I'm glad they aren't working for my software company...

diligently reporting back that a fresh install fixed almost all of the lagginess i mentioned earlier today. took forever to back up all my crap, though.

Phone is settled down but then the weird animation stutters randomly creep in, apps launch slower.

I honestly cannot stomach this sort of regression in a one year old phone. I'm scrambling to get back to iOS 8 and hope my back up is going to work.

iOS 8 was a mess on launch too and I think this about my last rodeo with an iPhone. Way too expensive for this sort of nonsense.
This!!!
Has anyone started to notice a pattern?! I first realized a pattern with my 5s when the 6 was release. With every new generation of an iPhone/iOS the previous model takes a sharp drop just before the latest model drops... I noticed when the 6 came out and we had a stable iOS ver, the phone's touchID authentication speed, app launching and general usage performance was butter smooth... Now all of a sudden the touch ID's unlocking time has fell off the cliff and slowed down noticeably,(ironically when apple announces a faster touchID sensor). In addition the time it takes for an app to actually launch has slowed and every now and then there are those jitter and hiccup's that androids are all too famous for.

Its almost like planned obsolesce to an extent.

And for the sheep who actually think iOS9 magically demands so much more resources that the phones are starting to slow down try running an app like "Status" and look at the ram and CPU usage... You'll noticed there is plenty of ram and cpu power idling yet there is bogging down of the GUI's animations..

I had 400MB / 1GB of ram available with a fluctuation of 7-18% CPU idle consumption... This makes absolutely no sense. Especially regarding the touchID's authentication slowdown... How much resources does it need to frigging authenticate all of sudden?

The performance is generally noticeably worse while indexing, obviously you can't really tell until you've used it in a non-indexing state.

+1

After a few hours my lag disappeared and I'm full turbo now. Whatever indexing is, Apple should let people know. Props to the community here for clarifying.

iOS9 has no lag.

Welcome to pretty much any x.0 release.

That said, as soon as you referred to others as "sheep" almost out of nowhere, anything you might have had to say pretty much lost any weight behind it.

9.1 beta is even better. It's actually quite fast on the Plus. They've obviously been working on coding efficiency for the Plus.

I don't know if you've tried today's 9.0 release. It's a different build from last week (last week GM was 13a340 and today's is 13a344) Since it was a newer build I downgraded from 9.1. And it actually feels better than 9.1. And safari hasn't been crashing on me. (In 9.1 it would crash trying to play videos sometimes.)

It might be wise to upgrade to 8.4.1 from 9.0 while Apple is still signing it. Once they stop signing 8.4.1, you'll be stuck on 9.x forever and there's no going back. I kinda wish I never got rid of 8.3. :-(

i did, on 6 plus its laggy as hell. if animations are turned off its fine but with it on the multitasker is a bitch to use with the lag. got rid of 9 and went back to 8.4.1

see you 9 when you reach 9.1.5 maybe!!
