Is there any point at all in turning on WiFi when the 3G speeds are so fast? Seems like it would just drain the battery constantly searching for hotspots etc. With a 5GB plan there is little risk of going over the data limit on 3G.
Got a tip for us?

I try to turn off WiFi whenever I know I won't be using it. But I usually end up forgetting, maybe with the lower battery life of the 3G I will remember more.
If you know that you won't have a WiFi signal it could be efficient to turn off WiFi. It is always scanning for a hotspot, so by turning it off you are stopping the constant scan, which will help battery life. But it wouldn't be efficient to turn it off in order to use 3G when a WiFi hotspot is available.

True, I was going off of the interpretation of he was in a hotspot, but since 3G is fast enough and people generally know WiFi is a power hog that just sacrifice the little speed difference for better battery life with 3G. Which actually isn't the case. 3G is more of a power hog then WiFi.
