I've been thinking,if wimax really is realitivly similar to wifi,but on a much larger scale,why is it that wimax adds about 300-400mA to the phones already discharging battery.? Like for say,on 4g and web browsing my 3D usually is in between about 300-600mA. Now keep in mind thats how much its using per hour,and on wifi my 3D uses about 100-300mA per hour. If indeed it is similar,why the drastic battery drainage?
