It'll only drain your battery when scanning for new networks. So if you don't set it to notify you on new open networks, the battery drain from it will be close to nothing I presume

I have my WiFi set to always on and it actually helps battery life since it stays connected to the access point.

Settings -> Wireless & Networks -> WiFi Settings -> Menu -> Advanced -> WiFi Sleep Policy, Set to Never.

I'm just going to add on to what others have said. WIFI won't drain your battery if there's constant WIFI signal. If you're going from your house to somewhere else with your WIFI on, it will drain your battery. This is because it is now constantly searching for WIFI signals and since you're moving, it will not attain one. Turn your WIFI off when you leave the house. There's a stock setting widget for this (it enables WIFI, volume and brightness). You can also download an application like Locale to manage your settings based on time or GPS.

I think you can use juicedefender to turn off your wifi when out of range of known networks, or locale.

I would argue the wifi draining the battery when not connected to an access point. When the N1 isn't connected to an access point the WiFi radio is just listening for a wifi network. It's not actively transmitting when it isn't connected. I'm running WiFi only, no network data, and at the end of the day with moderate usage I end up around 50%. If my usage is very light, little or no wifi usage and phone use only I've seen my phone at 70%.

So when I'm at work and there are no wifi spots nearby, my phone still says "scanning" all the time. Is this not draining the battery?

I have never turned of my wireless and it just connects whereever i have an access point. It hardly drains any battery, honestly.

Turn off notify on new networks etc and i have setting, power save when screen off.

Flawless!
