Even four years ago the wifi chipsets used in mobile handsets dropped down to a fairly low power state when on, connected, but idle. It can't be that they've gotten worse since then.
When you start actually pull/pushing data the power drain climbs, but really it's all in the same ballpark with LTE/4G. Maybe if you were on Edge you'd be better off on the cell radio.
These things *still* have essentially 5 hours of "high drain" battery capacity (test this - play a game for an hour on a full battery... check... you'll be down 20% with 4 hours est. life left :) ) and it doesn't really matter what bucket you pull those 5 hours from.
About the only time it would make sense to NOT have it stay on all the time is if you're sure you're not going to have any wifi coverage. Like driving cross country, or visiting Kansas :)

I went from using ~20% during the day to using ~50% with wifi on. Others may well see the opposite effect - running the extra antenna costs power when not using it, but generally saves power when you *are* using it. So if you're really doing a lot of polling email, or streaming music or video, then always-on wifi will probably improve your battery life. If you aren't doing these things, then the battery benefits are much more iffy.
I'm going to run with wifi on for a month and see what it does to my data usage; I still easily make it through the day even with the increased battery consumption, and the increased use of wifi may enable me to reduce my data plan.

This is from last night. WiFi (always on), cell/data on, locations on. I did have plugged in prior to going to bed. Laid down and checked some sites, forgot to plug back in. I had ~20 emails this morning from various accounts. Light use since then, now down to 54% (5hrs). Not sure if this is typical.

Ok I did this myself and from what I learned, WiFi really consumed battery. I have turned my WiFi off to test the theory, looks like as long you have 3+ signal bars of LTE you'll most likely have better battery life than being on WiFi all day when connected. IPhone (which I came from) saved alot of battery when connected to WiFi, but on network, it consumed greatly. Its strange how iDevices handles WiFi very well. But for Nokia, I see otherwise so instead of WiFi, Nokia can handle LTE where iPhones couldn't.

If your battery is halving with WiFi on then it must be a serious bug in Windows Phone. Or you have some app that is constantly using the WiFi connection all the time, which it shouldn't. Again probably a buggy app.
