    Would you say this kind of lag when scrolling is normal for an iPhone 7?

    No idea. Looks awful though. Just tested and my iPhone 5 on iOS 10 scrolls everything smoother than that.

    depends on many factors tbh (e.g. background activity of the phone, etc.). It doesn't look too horrible in my view

    While it is not quite as smooth as my 7+ it is not an excessive lag.

    As I watch the clip myself I can say it looks a bit better than it feels when I'm using it, probably because when I use it I know what to "expect" so to speak, if you understand what I mean? But it is a bit discouraging to hear ppl say it's not excessive or that bad when even the mail.app lags on what is said to be the fastest phone around. I am REALLY hoping it is a software problem that can and will be fixed.

    If I were you, I'd try a software reset. That COULD fix the problem, if it's software related.

    I have done an iTunes complete restore from DFU and also updated to 10.1 beta with no difference. When the phone is restored and all apps are being installed the lag stops only to come back after.

    Obviously it's difficult to verify the amount of lag from a video, when you say it feels worse than it looks. Is there a way for you to test another iPhone 7 and compare the amount of lag there is between your phone and the other device? If there is a considerable amount of more lag and restoring the software doesn't help, I'd take it into an Apple Store

    That is kinda the point of this thread, to ask other iPhone 7 owners about their opinions.

    iOS 10 on iPhone 7 / 7 Plus is choppy as hell.

    My 7 due to the frame drops feels slower than my 6S ever did running iOS 10.

    Have a look at a few of Chris Perillo's videos and his rants.

    That looks horrible. Exchange it.

    I have heard others mentioning lag on the 7, but I just am not seeing that. I also have an SE and they run identical. I am very sensitive to UI lag, so it would annoy me.

    Mine is smooth. Just tried a few pages on different forums/graphic-heavy sites. The only time it lags is when a page hasn't finished loading and I start scrolling, just like Safari or any other browser on the Mac. Once the page has finished loading it's really smooth.

    Safari runs smooth for me too, which is kind of weird. Seems it might be that the energy saving cores that I am guessing is in use in for example mail.app isn't fast enough to keep it smooth?

    It is probably facebook, reddit or a google app running in the background gobbling up all your ram. Also hard to see the real effect unless recorded ag 60fps. No iphone ive used behaved as laggy as that, always very smooth, unlike android

    I recorded via Quicktime, don't know the FPS but the video isn't making it look worse at least. Seems Chris Perello that was linked earlier sees what I am seeing

    Although I'd originally decided to keep my iPhone 6, I couldn't resist Verizon's offer to trade it in for a $650 credit against an iPhone 7. I just got the new phone yesterday, and one of the first things I noticed was slight stuttering in screen animations and scrolling. It's not always there, but it happens enough to be noticeable. I'm disappointed to hear from you that iOS 10.1 beta hasn't fixed it because I thought I saw a post from someone else that said the update did fix the stuttering. In any event, I'm fairly confident that this can be addressed in software.

    well im on a 7 (4.7) and its totally smooth with no lags. If I run puffin browser on the galaxy s7 though it looks like its running at 20fps. Id check your background apps and see what happens if you stop facebook fir example, I saw somewhere that was causing problems

    The energy saving cores could potentially play a part in unoptimised apps but I'd be surprised if thats the case with Mail, of course never say never. The low power cores I'm definitely curious about in general, they draw 1/5th the power of the main cores, so does that mean we can expect the low power cores to be roughly equivalent to an A7 or A6 in performance. That I'd like to know.

    Anyway, what version of iOS are you using? Stock or betas, there's always the possibility that the latest betas are better optimised.

    Not that I don't believe you but if your phone is completely smooth maybe you could record the screen? I always turn of background app refresh for facebook.

    I am running 10.1 now, but have tried 10.02 also with no difference.

    That would be a hastle, maybe later - do you have the 7 or 7 plus? I have a 6+ also and its running ios 10 really smooth also, Im thinking you may have a defective unit here - Im pretty perceptive about fps and stutter and never seen an iphone run like your video

    Curious, I've seen people on the dev forums mention lag but it was ironed out for them in the latest beta.

    Does this happen straight after a reboot, or is it only after a period of use? Is it affected by things like turning on reduce motion?

    I don't know that we can fairly compare the 7 series to older devices as the low power cores could well be playing a part. Whereas on the older devices they're only ever using the two full power cores available to them.
    My 6+ (Stupid bloody wait time for my 7+ :() is buttery smooth and it only has half the power of the 7, which leads me to think it is indeed related to the lower power cores.

    Yeah I did notice, all I was saying is that it's not quite so relevant to compare to the 6/6s/se/whatever due to the difference in the architecture. 7 to 7 comparisons are obviously fine as they share the same architecture and can be reliably compared.
