Ever since day one of owning my 4S, my battery life on AT&T's 4G/3G/whatever network has always been absolutely terrible compared to wireless. Is this normal? I get double the time on my battery using my home wireless network than I do with data. Doing average work with my battery, I get about 9 or 10 hours on wifi total, 4 or 5 max using cell service total. An hour of lite to moderate usage including sending a few emails and texts, checking Twitter and briefly surfing the web on my wireless drains my battery to about 93%. The exact same lite to moderate usage of texts, email, web browsing and Twitter with wireless turned off drains my battery to about 80%. Two hours of using my iPhone with AT&T and my battery's down to around 65%. ... Rediculous? Furthermore, you can't turn 3G off using AT&T, but even so, the drain in battery using cell service as compared to wireless just seems incredible to me. Is there something wrong with my phone or more likely, my phone service or connection that's causing such a dramatic drain in battery use when wireless is turned off? Is this normal? I'm using a factory unlocked 4S that I bought straight from Apple, and again I don't have any problems with my battery when connected to wireless or when on standby.
