Default Does enabling data on 2g use more power?

I'm using the power control widget to toggle Wi-Fi, 2g/3g, Auto Sync, and Mobile Data. I like to keep it on 2g and auto sync off unless I need to use the Internet.

I'm wondering if enabling mobile data will use more power even if I have auto sync off and no other data is going on? Would the power consumption be the same whether mobile data is enabled or not?

I want to leave mobile data on in case I lose the phone and I can use a locator app to remote track it.

I think it will still use a bit more power, but it wouldn't be as large as if there is no ongoing autosync.

There would be no difference in power drain if only 2G is on. If 3G/4G is on it would still be negligible as long as you are in a 3G/4G coverage area so the phone is not constantly searching for a 3G/4G signal.

Āll that assumes no active data transfer of course.

I've measured the drain, and while on standaby, 2/3G will use almost no battery at all. (given that you have a good signal)
