Hey guys, I'm new to this forum but hopefully you can help me. About a week ago, my iPhone 4 (with iOS 5.0.1) started having trouble with wifi. Specifically, when I go into settings everything moves extremely sluggishly. When I click on "Wi-Fi" it takes several seconds to proceed to the next screen. Similarly, clicking "on" or "off" takes a few seconds to register. But the problem is that it will not find my wifi signal. Interestingly, I've reset network settings several times and that temporarily fixes the problem as when the phone turns back on it picks up the wifi signal flawlessly. But it drops the signal after about 15 minutes and then settings starts to act sluggish again. The exact same thing happens when I reboot the phone, and also from the two times I restored it from itunes. I've also tried exiting out of all apps and widgets and this had no effect. On top of all this, twice in the last week my phone has gone from being fully charged on my nightstand to completely dead over the course of just an 8 hour night. Has anyone else had this problem? Are there any solutions you can offer me? I realize my best recourse would be to take it to an Apple store but that is a significant inconvenience that I would like to avoid except as an absolute last recourse. Thanks to everyone in advance.
