This must be phone dependent. I have my Blackberry 8900 on wifi all day and it maybe goes down by 20% in 24 hours. I'm currently in Mexico so I leave the GSM radio off and it seems that the battery lasts longer this way.

I there a way to turn GSM off on Android/CM? That would be great for situations where I do actually have wifi coverage.

I believe when Wi-Fi is running that GSM data is automatically disabled. When you turn off Wi-Fi you'll see it takes a few seconds to re-establish the GSM data connection. I know you can turn off the roaming data. You may need a rooted Android ROM to completely disable GSM. Some people on XDA Developers have talked about that.
