You're not going to get low power consumption with IP. That's a problem for small battery powered devices.

You will as long as the protocol is designed to be power efficient.

I agree though that existing WiFi networks are hard to connect to from devices where battery life needs to be measured in months.

Thread is low power like Zigbee even though it is IPv6 over the same radio. Implementing IP stack takes very little these days.
