    I've got a 4S and the wife has a 4.
    Does upgrading to iOS 7 have any drawbacks? I.e. performance or certain features not available?

    Can't speak to the 4 but I put it on my son's 4s and seems to be working fine so far.

    iOS7 works flawlessly on my 4S. No battery issues, no lag, no glitches.

    Works just as seamlessly as it did on 6.0.

    I did a restore, iTunes install and set up as new.

    NO COMPLAINTS. 4S is still running beastly! :D

    It runs fine on my 4S. Some little lags and stuttering here and there but nothing I can't stand.

    I installed IOS 7 on my iPhone 4 this morning and its running better than IOS 6. Everything is very smooth on IOS 7 :D

    Define "smooth". A lot of people are saying the animation framerate is bad.

    From what I have seen, people are not complaining about the animation framerate, they are complaining about the animation duration (and the fact that they are non-interruptible.)

    Running perfectly on my 4S. Hearing about more issues with the 4.

    Who the F uses the 4 series ? Apple shouldn't even updated these dinosaurs!

    Running nicely on my 4S, however it is KILLING my battery life. 2 hours of moderate use (a little podcast playing and occasional email checking) takes it from 100% to 55%). I'm fine because I'm gonna upgrade my phone soon anyway, but if you're sticking with the 4S for a while, you may want to read up on the battery issue or wait for an iOS update.

    Works fine on my 4. But maybe my standards are low.

    It's run well enough on my 4S to use everyday no problem. Some stuttering/jerkiness randomly in animations. The 5 is noticeably smoother.

    Nice attitude.


    Updated my daughter's 4 last night and it seems to run fine. Certainly good enough for her.

    4S dinosour is still selling on Apples website. I don't see iPhone5, where is it? Maybe they discontinued it due to scratchgate or bendgate, I don't know. :eek:

    Btw, the 4S is running iOS7 almost smooth as iPhone5.

    iOS 7 is trash on my iPhone 4.

    Animations are slow and lagging
    imessage is slow and laggy
    good luck changing wallpapers
    Transitions in an out of the multitasking card view are slow

    Safari is fast
    and my apps seem to be working fine

    It's working fine on my 4S. The battery took a big hit, but I turned off the Background App Refresh and that seemed to help it a lot.

    Isn't there already a multitude of threads regarding performance on these devices? The search function would reveal that ;)

    Running fine on my iPhone 4.

    It is a bit laggy but not worse than ios6 was. As someone mentioned taking photos is much much faster than it was with ios6.

    iOS 7 runs fine on my iPhone 4

    Reset my iPhone w/o iTunes then updated OTA to iOS 7 and then reset it again.

    I have to say, I'm impressed iOS 7 hasn't made the iPhone 4 unusable compared to updating the iPad 1 to iOS 5 which caused it to slow and crash significantly. I feared iOS 7 would totally make the iPhone 4 unusable. Its slightly slower than before, but no crashes and the animations while slower don't stutter.

    Entering a passcode is a little bit faster now, mainly to do with how the numbers are shaped now. iOS 6 tight square-spaced numbers made it harder to enter, its much easier now with iOS7's circled and more spaced out icons. Icons appearing takes a second longer due to the new animation.

    Notification Center/Control Center
    No lag what so ever. Yes, it doesn't have the blur effects newer devices have. Spotlight to me is better than iOS 6. There was a little bit of lag when you swiped to the left on iOS 6.

    Core Apps
    This is when I begin to notice a little slow down.

    Phone, Mail, Messages, Photos, Weather, Clock, Notes, Reminders, and Game Center I noticed a 2-3 second delay. Game Center was by far the worst, took about 5 seconds to load.

    Safari, Music, Camera, Maps, Videos, iTunes Store, App Store, and Settings I felt were either able to be a little faster or at least maintain its loading time considering all the new features added.

    Battery Life (charged it over night, started using it at 7:30 AM)
    100% - 7:30 AM
    50% - 3:16 PM

    iPhone Usage Data (Time Since Last Full Charge)
    Usage - 3 hours 23 minutes
    Standby - 7 hours 38 minutes

    -Wi-Fi and 3G turned on
    -Bluetooth turned off
    -Brightness set at 50%

    I only downloaded apps that supported iOS 7 and had newer UI elements. Most of them worked fine, Facebook had the worst lag and took a good 6-8 seconds to load. Evernote, OpenTable, Pocket, Shazam, and TED were fine.

    It's working fine on my iPhone 4. It runs at about the same speed as 6.1.3, which was always fast and smooth on my phone. Apps take some time to load as usual but all of the animations are smooth.
