Even if highly optimized, there will always some power drain. As I remember you were the one complaining about the battery life. It will not improve when you add wifi.
Even if they redesign the complete GEN3 to a extremely energy efficient GEN4with wifi, the same device will last longer with the wifi switched off.
You won't get wifi for free
