    How slow is IOS 7 on the iPhone 4S? I'm looking for a used iPhone 4S for one of my family members and noticed most of them come with IOS 7. How's the performance and battery life on it? Thanks

    It was pretty smooth on my old 4s, didn't lag too much though turning off parallax motion and animations tweaked performance nicely.

    Never had any performance issues, couldn't comment on battery drain though as had it secondhand, also had iOS 7 on it from when I got it.

    It's fast to me compared to my 5s for calls, text and small apps like Facebook. Games and battery life though? Different story.

    I'm using iOS7 on my iPhone 4S and it's perfectly fine.

    Same here. My 4S is perfectly fine on iOS 7. I tried iOS 7.1 Beta and it does improve it somewhat, but its far from the the crippled experience you can expect on an iPhone 4.

    It's not slow, not by any stretch of the imagination.

    One person's "perfectly fine" is another's "slow".
    There is no doubt that iOS6 was faster even on the iPhone5 so you can readily assume that with the slower hardware on the iPhone 4S and iPhone4 that iOS7 is going to be noticeably slower than iOS6. Whether you can live with it or not is entirely subjective.
    Oh and iOS7 is a battery hog. My iPhone5 gets one third less runtime per battery charge cycle.

    Faster then iOS 6 for me. Judging from reading this forum I must have had a problem with iOS 6.

    I turned off some settings and I'm quite happy with it. Thankfully (or not) I haven't had enough hands on time with the 5, 5C and 5S to compare and make my phone feel slow.

    Only app I noticed that is annoying slow to load is FB. But it works fine once loaded.

    More or less this. Some people think the speed is okay still, but it's definitely slower at navigating the OS than 6 was. Opening and running apps doesn't appear to be much slower to me, at least. But moving around is a lot slower.

    It wouldn't be as noticeable if the phone is for someone who isn't used to an iPhone already, and supposedly it is addressed in 7.1... Which should be out after the harvest moon of 2037. ;)

    It's slower because of the animations, just wait until you use 7.1

    Depends what you mean by slow. For me I'm running 7.1 beta 4, and it's perfectly fine on both performance and battery life. I get through the whole day with 3G on and using my phone for texting and emails.

    It's slow. It isn't unbearable or anything but it definitely is slower than iOS 6. Animations are longer and laggier, you can disable them but in a side-by-side comparison with another 4S on iOS6 it's still slower. Apps (Safari, Messages, etc) are generally a little slower as well. Also, when waking the phone from sleep there is a slow fade-in animation, it looks nice but when you're trying to check the time quickly it gets annoying.

    I'll put it this way—I was quite content with my two-year-old 4S (aside from deteriorated battery life) and was even considering squeezing another year out of it. iOS 7's performance made me change my mind, the phone had not felt particularly slow or outdated to me until I updated to it. All that said, on my new 5S it is great.

    It's ok. It could be faster but it is definitely useable!

    It works fine in 4s but I imagine 7.1 will be last update for it.

    I'm curious too.

    The 4S hasn't been crippled by Apple yet. There must be another update for it (iOS 8). :D

    OK for me. Occasionally there are slow downs, particularly noticeable on the keyboard.

    my iphone 4s works perfectly on ios 7, especially on ios 7.1 beta .

    but its best to turn on reduce motion and turn off parallax, the experience is then awesome

    My iPhone 4s works well with iOS 7.04 having switched off some cosmetic bells and whistles. Having re-calibrated the battery on a monthly basis, the battery life isn't too bad either. (Only use WiFi and 3G when needed and switch off when not required)

    My experience too. It is slower than iOS6 but useable. Battery life is horrible though.
