My friend and I are debating about whether or not WiFi or 3G uses more battery. I can't really seem to find this (yes, I searched).
Personally, I'm always in range of WiFi and I use my phone a lot (but I also have Max 3G reception everywhere). Would it be better to leave WiFi on to save battery or use 3G?
Info: WiFi has less range than 3G so you'd think it would be less battery usage, right? But does it transmit/receive more when you leave it on? I have my phone configured to keep the WiFi connection even though the phone is idle.
