Well it's been over 36 hours now and my latest 6S+ still has the unlock lag. Normally I would restore to remove it but I'm testing out the experience of others here who say that their lag disappeared in a few days. Quite what the phone might be doing is beyond me, because I have Spotlight Search toggled off for every app and I haven't installed a backup.

Try having it since release day! Tried every tip on here. None of them work. No clue what it can be anymore

My lag gets better at times, but never actually goes away.

On a side note I was chatting with a senior Apple Care person today about a different issue and asked about the unlock lag. He said neither he nor his colleague had ever heard of the problem and suggested I take my phone into the Genius Bar.
 
I'm at a loss. I'm on my third 6S+ right now, but none of my returns were for the freeze/lag, but right now I'm battling with #3 to get rid of the lag and freezing.

iPhone #1: Came with 9.0.2, I had lag. Updated to 9.1 without wiping, lag was worse, along with homescreen freezes after unlocking. I then restored one more time through iTunes, and all my lag and freeze disappeared. I returned it for a faulty headphone jack.

iPhone #2: Came with 9.0.2, with lag. Upgraded to 9.1, then wiped it and reset it. Lag disappeared. All good. Returned it for wonky power button.

iPhone #3: Got it today. Again, 9.0.2 out of the box. When I got home, I decided to just skip right to iTunes, and restored it and updated it all at once to 9.1. Everything seemed good, then suddenly, homescreen started freezing pretty bad after unlock, usually after phone had been asleep for a few minutes. Then, I decided to try an iCloud backup from yesterday. Well, still getting some freezes. I'm going to try another iTunes restore.

I'm continuing to work on this. If I can't get this worked out, I think I'm moving on. No way a $900 phone should be this much work.

Have you considered that an app might be at fault? I'm thinking of the shenanigans in the Facebook app until its very recent update. Stuff like that can bring your hardware to its knees. From your chronicle, it seems that each of your issues has followed a restore.

Maybe it's just 9.1 issue. I didn't have this issue prior versions but seems like 9.1 is the issue. Hopefully Apple will bring a fix. Not sure if 9.2 beta fixes the lag issue. But I guess it's hit or miss.

Mine has had lag straight out of the box. I switched it on, went through the initial settings, chose not to install a backup, got to the homescreen and then went to make a sandwich. I came back to the phone 10 mins later and had the unlock lag. That's on a new phone with nothing whatsoever installed on it.
I have since installed some apps and the unlock lag remains. I'm just going to see if it disappears of its own accord before restoring through iTunes.

Mine's on 9.0.2 as it came out of the box...

By restore, I mean to a stock build of 9.1, done via iTunes with the Restore button. I'm setting up as new each time, not from a backup. No apps.

My latest test is just a reset from the phone itself into a fresh 9.1 install. I'm not installing ANY apps or changing any settings. I might leave it that way over night and check it in the morning, just to avoid any possible "settling in" though I'm not sure I buy that when it comes to a frozen home screen.

I do know that I managed to get my last two freezing/lagging iPhones to behave. So I'm hopeful that eventually I can get this one to fall in line as well. It just happens to be the most stubborn of the three, but from a hardware standpoint, it's the best of the three (no headphone issues, button issues, and the lower left dark blotch is better than the last two. barely noticeable on this one).

Been through 3 handsets - all have the same unlock lag.
Doesn't get better after a few days.
Its only 1-2 secs, but enough to be noticeable.

Given up going through handsets as Im convinced its a software issue now. Awaiting 9.2 to see if that makes any difference!

I waited 3 days for my lag to go. No dice.
It was a phone with no backup on, I set it up as a new phone through the initial settings and never connected it to iTunes. Well get this, I downloaded some of my apps from the App Store and did an iCloud backup. Then I erased all content and settings, went through the initial settings for selecting the language and connecting to WiFi etc and chose to restore from the iCloud backup I'd just done.

Now I have zero unlock lag, and my battery life is WAY better. Strange!

I don't have the time or energy to sit through dozens of restores with the hope that one might end up being lag free. The issue is on Apple's radar so I'll just live with it until they fix it.

Unfortunately I doubt 9.2 will fix it as that's being done for the iPad Pro release. The earliest I think a fix might be possible is 9.3, which probably won't be out till next year. Of course with the rumors that the next iPhone will be out in July, they may wait till iOS 10 to fix the problem, of ever.

I couldn't live more than three days with that lag, it was terrible. A £700 phone doing that out of the box? There's no way I'd be waiting for a 'possible' iOS update to fix it. Been there with the 6+ and the fix never came. Thankfully a simple restore sorts it but if it didn't then I'd be getting a refund.

I've not found that a restore fixes it. The last restore I did was lag free for the first 12 hours and then the lag came back.

Considering a restore takes about 30 minutes to restore and restore from backup, followed by another 15 minutes setting up the phone, followed by around 12 hours waiting to see if the lag comes back, I'd spend more time on one restore than I would in a month waiting the one extra second or two for the phone to unlock.

If it's still doing it after 9.3 comes out, I'll swap my phone since I know there are some that have no lag, like my first one. I restored that around 5 times and never saw lag once.
 
"I'm at a loss. I'm on my third 6S+ right now, but none of my returns were for the freeze/lag, but right now I'm battling with #3 to get rid of the lag and freezing."

I had that same issue with my first one, swapped for another. Lag present. So I did a DFU restore and now lag is gone. Even after long periods of inactivity. No harm giving it a go.
 
Getting lag whenever I press the home button to get back to the home screen. The lag is when I am at the home screen, it's unresponsive for a second and I have to press again to open the app I want or to navigate.

Might be nitpicking but I come from my note 3 and don't have that problem.
 
I wonder if there is any connection between lag and chip type (Samsung / TSMC). My 6s Plus has a Samsung chip and lag seems to be slightly worse than my friend's 6s Plus with the TSMC chip.

Samsung here with zero lag. I did have lag but I fixed it. Two ways to do it, either restore through iTunes, or the easiest way is to do an iCloud backup, erase all contents & settings (ie wipe your phone), then restore the backup you just made.

No work
 
Writing to follow up. In case someone hasn't read my other posts in this thread, I am on my 3rd 6S Plus, 64GB, Space Gray, no idea what chip or build week. I ended up fixing the lag on the first two, but they were both returned for other reasons.

iPhone #3 was the most stubborn of them all. Here's how it went down.

9.0.2 out of the box.
Set it up temporarily in the store just to get calling and texting going, and drove on home. Went straight to an iTunes update, restore and set up as new. No dice. Lag and homescreen freezing. For giggles, I decided to try the lag-free working iCloud backup I had from phone #2 that I made earlier in the day. Upon rebooting from that iCloud backup, the phone got stuck on a full blast brightness white screen with black Apple Logo in the middle. Stayed that way for 15 minutes and the phone was pretty hot (probably from the screen brightness being up to 100% for so long). I two-finger reset it, and when it rebooted, it went into the setup screen as it should have done automatically. Went through the setup to get it up and running, and when it came time for the apps to start downloading, I put the phone down and left it alone for an hour or so. I came back, apps were all there, lag and freezing were totally there. At this point I said, "one more shot at this and I'm done."

It was pretty late, and I stayed up a little late to do it, but that was part of the plan. I again did an iTunes restore and set up as new. After it was done, I purposely didn't check it for lag or freeze. I use iCloud Photo Library, and I know that can take a while to re-sync. I turned that on, plugged my phone in to the charger, and left it beside untouched overnight. When I woke up in the morning. No noticeable lag, and definitely no homescreen freezes. I've since installed all my apps and set everything up the way I want it, and still no lag or freezes. I did this last restore on Friday night, and used it all day Saturday and Sunday with no issues.

I'm not into jinxing myself and saying that it's all in the past, but this really has seemed to have done the trick. I also remember with phone #1, I did the same thing where I restored from iTunes, went through the initial setup screens, and then let it sit overnight, and I also woke up to a lag free phone on that occasion.

So, long story short. Give it a shot if you haven't already. Restore it through iTunes, run through the initial setup, then put it down over night. If you use iCloud Photo Library, turn that on and let that do it's thing too, because that can take a while and potentially cause extra lag.

9.1 just seems really temperamental. I ultimately got rid of the lag on all three phones, but the path to get there was a little different on each.

Are you using touch id? No lag with touch id?
 
I guess whats happening is that the mcu takes too long to wake up when it goes to deep sleep state. Therefore apple needs to fix this in their kernel. I hope this is fixable though otherwise it can be a chip problem.

Thanks for the write up though the way you did makes no sense to me.... It should be something else or just pure coincidence.

I have fixed my lag suuuuuper easily on two separate phones. It can't be hardware.

I agree the whole thing seems inconsistent, both when it happens, and what it takes to get a non-laggy state.

Point is, if one restore doesn't work, try and try again. And let it sit overnight after you do it. I've gotten rid of the lag on 3 phones out of 3.

Could it be...
"something else"?
Not sure what something else is, but of course, there's a lot of factors happening here, but in my opinion, hardware problems are WAY more consistent than software problems. The inconsistency of all of this nonsense does not speak to a hardware issue at all.

"pure coincidence"?
Not when I've managed to fixed all three. Unless you think the lag all just disappeared all by itself for some other unknown reason.

All I know is what I've done and what results I've found after the steps I've taken. If I had 100 more phones to wash the lag out of, I'm sure in the end I'd have a more tried and true method for taking care of things, but for now, hopefully my experience adds to the conversation in some way and helps someone out.
