    Ever since I updated to iOS 9 my device has been extremely laggy....some apps freeze to the point where I have to reset just to get out of the app. Anyone else having similar issues?

    I would have to agree with OP somewhat. After installing IOS 9, my 6 plus doesn't run as smoothly. I haven't had apps freeze up on me but where I find it lags is transitioning between apps. Especially from the recent apps, and the transition effect going between folders back to the home screen.

    My thinking is maybe iOS 9 is built for the new 6s and 6s plus with 2 gb ram? I could be totally wrong though

    Hopefully the next update will smooth all this out.

    I would hope that isn't the case. If it is... Our devices are ALREADY obsolete!?

    I'm seeing the exact same behavior on my 6 Plus whereas in the 5s it's as smooth and silky as can be.

    Mine has been pretty smooth since the update... Only issue in the beginning was some apps closing out, due to not being updated to be compatible with ios 9... most have already fixed their issues... so all good... hope a restore helps you out... clean installs were almost always necessary when i had android

    This is what I see happening as well with transitioning through apps.

    Most likely the apps are lagging because there not optimized for iOS 9

    I thought it was just me. I did a full reset and restored my apps and data. I did still have a few apps unexpected close on me after the reset. I'm going to give it a few more weeks and hopefully app developers will update their apps.

    One feature that I thought was a tad faster with iOS 8 was the fingerprint unlock.

    I am having the same problem. Games are horrible now. Using task switcher almost always lag. Did a clean install from iTunes twice now. No change.

    Was super laggy on my 6+ too until I updated to 9.0.1 yesterday. It's not perfect but much better.

    My 6 plus (space grey, 128gb) was super laggy after iOS 9.0

    Just updated to 9.0.1 and immediately I noticed it is so much smoother. Mainly with the recent apps screen and scrolling thru the recents app tabs, as well as going in and out of folders on the home page.

    For me this update has made a huge difference in smoothness. Very happy with this!

    My 6 Plus is far from smooth. I did nuke and pave my phone when iOS 9 came out. I'm getting hanging apps, jerky transitions and delays in multitasking popping up. I'm hoping as bugs get fixed this gets ironed out. The fact of the matter is though, these types of problems have always been on the iPhone 6 Plus. It's a big hamstrung because of the screen size and 1 GB of RAM.

    I still love 6 Plus, but it's never been wart free. Don't even get me started on the rotation nonsense when you unlock the phone.

    For once I have had zero issues at all with either IOS 9 or 9.1. My 6 Plus has been running like silk.

    When I did a clean install, it was not nice, I did a dirty one, and it seems OK, go figure lol 6S+ here

    My experience on my 6 plus has been terrible since updating to ios 9! TouchID is slow, screen rotation is laggy, getting in and out of apps is slow! Texting has been weird as well...as there is some lag to that as well. Ughhh

    I've updated to 9.0.1 and it is better. It's not as smooth as iOS 8xx.

    I think I'm going to do a clean install to see if it will fix the lag issues.

    I'm having issues with my 6 plus as well. There has been considerable lag that could be due to apps not being optimized however I'm seeing it in just closing or transitioning screens. I've done a clean install through iTunes however still no luck. This rotational issue has to be addressed. I'm tired of having to orientate my phone every time I unlock it and I realize I can lock the orientation however I shouldn't have to. The bigger question I have is what is Apple doing to address these issues? The last update wasn't relevant to the issues with 6 plus I've been reading about or experiencing and I know we all aren't having issues but the select few all experiencing the same issue is an opportunity.

    iOS 9.0.2 has been better for me. Agree with Bigwoodque on the rotation problems. They continue to exist, although not as bad as on iOS 8.x.

    Trees I agree it's not as bad as iOS 8 but still hasn't been fixed and now this lag issue is just adding fuel to the fire.

    I'm having all the same issues in my 6 plus. I have restored as new, reset settings, tried 9.1 betas and still laggy as ever. I wonder if it is affecting certain models. Mine is a 128gb.
