Which uses more battery - talking or texting?

If you're running out of battery, for example, which is the best way to contact someone - a quick call or a text?

If you have a PC with a mic, type a paragraph and save the text file. Then record yourself and save it as an mp3. Which file is bigger? Yes, the recording. (I know, I know - simplified, but still..)
In adddition, during a talk, your phone has to modify and demodify 2 signals - you and the other party. And if it's 3G phone...
Also, the other end's words need to be amplified by your phone so you can hear them through the speaker.
On the plus side: talking allows the other party to butt in when there's a misunderstanding. No need for 5 texts to clarify a point or a typo, or to decide who says, "goodbye" first ;) So, there's a social and psychological element. Plus, if your spelling sux, speaking might help...

Nutshell: talking uses more energy.

Depends how much you are planning to say. Speaking for 15 seconds vs. typing for 30 seconds would probably eat less battery, if call is connected right away.
When you text screen has to be on, when talking screen is off. If you have a big screen in broad sunlight talking will be more efficient.
