Is that with WIFI connected or not? In my experience with WIFI connected to a network the phone uses less power than it does with WIFI disabled and using 3G/H+.
BUT with WIFI turned on but not connected to a network it does use a lot of battery, presumably due to scanning for available networks. To avoid this I use an app called WIFI Power Saver that will disable WIFI after a defined period of time that it has lost connection.
