iphone 4 with ios5 lag

[peterpotter]

I'm not sure if its mental, or if the apps are just requiring more from my phone but I feel like my iphone 4 lags from ios5. Does it really require that much more processing power and am I just imagining things and trying to convince myself to get a 4S

My iPhone 4 with iOS 5 was very snappy. Of course I only used it a few days before I got my 4S, but I never noticed any lag. If it continues, you may want to restore as new.

Try setting it up as a new phone.
