I live and work in Westchester, NY, a close -in suburb of NYC where I have never had problems with dropped calls on my previous Verizon service on a nonsmart phone. Since I have used the iPhone 4s I notice that I get the "circle" instead of 3G going on and off throughout the day, even if I am sitting in the same spot with the phone. I don't think the phone call are a problem even though the bars fluctuate from 2-3 or 4, but I wonder if searching for 3G is causing the battery to drain.
I find the same problem in my home, where 3G seems unstable. My battery life is terrible, and I have used all the tips I have read to extend battery life to only some avail. I wonder why my 3G connection is so unstable.
To make matters worse, I have an iPad with 3G through ATT, and I have a consistent 3G connection all the time, even in the same places where Verizon 3G drops off.
I have called Verizon and reset the phone and the network and rebooted, but I still have unstable 3G. Has anyone else noticed that there is a problem connected to 3G with the iPhone 4s?
