Works great on my wife's 4s. Know what I think? I think it works great, but some people have apps that don't work great because they haven't been updated to by fully compatible with ios7 yet. Developer problem.
 
It runs well on my 4S. It's not quite as snappy as on my 5S, but it does run just fine.

If you haven't done so already, I highly recommend a clean install and do not restore from a backup. Install everything fresh.

This can make a real difference in performance.

Going to do this.

Can you or anyone reading this guide me to do it?
 
A friend of mine is using his 4s with ios 7 and he is pretty happy with it, no lag at all :)
 
Thus far ios7 runs great on my 4S though battery does not last as long as it used to
 
iOS 7 ran very smoothly on my iPhone 4, I imagine it runs better on the 4s, and it's great on my iPhone 5.
 
It runs better on my 3GS than it does my 5s;)

Actually, it runs the same on my iPH5 as it does my coworkers 5S...

All of the glitchy, animation FPS dropping, is present on his 5s just like my 5. iOS7 IS glitchy, but Apple will fix this soon. No WAY the A7 is designed to run that sloppy with iOS7.

Hang in there bruhs.
 
on my 4S iOS 7 is running spectacularly...which is not what i had expected...given that the A5 launched with iOS 4!

I had thought iOS 6 to be the last iOS to run smoothly on the 4S...but the way iOS 7 runs on it made me change my mind on getting the 5S. it's the iPHone 6 for me
 
There are some things that I do not like about iOS7 (the time wasted in animations; the persistent afterglow of keys used on the lock screen to enter the passcode; the failure to include a 'close all' button for open apps in the control center), but I presume these are global issues not associated with the 4S. I haven't really noticed much in the way of glitches or crashes.
 
It ran very well on my 4S right up to the time I traded it in for £££. Running a Windows phone until my shiny 5S arrives next week.
 
I have it running well on my 4S but I'm not totally sold on all the minimization. For example, I think mail and imessage are a bit drab. That's just subjective and I do appreciate that they're both given a very clean look. I just tend to like a bit of either color or darkness. Too much white gets old quickly, but I still like that it's different and works well on the phone.

Wow, I just wrote a whole paragraph in subjective perception

This made a big difference with my 4S. I just did this yesterday.
 
Running great on 4s here. I did have the few random reboots like a week after installing the GM. Did a DFU restore to the released iOS 7 in the morning then later that day iOS 7.0.2 dropped so updated to it OTA. All been fine ever since.

BTW there are a lot of recommendations to install fresh and not restore backups etc. While that is good advice and works well, if you do restore a backup simply following up with a "reset all settings" works fine too. Just run back through setting up your settings but all your other stuff remains intact.
