Well, that depends. If it is a regular corded phone, then the power used over the phone lines is minimal (in the order of milliwatts). If you're referring to a cordless phone, the answer is written on the power supply. Just look on the wall wart, there will be an output rating in either amps or watts. That is the maximum power it can use. It probably uses about half to three quarters of that on average.

How can you get your phone to work without a battery?
It can't work without power. (alternate answer) In principle there are a variety of ways to provide a phone with electric power. Of course, the simplest alternative to a battery is to use a land-line which draws current from the wall (I still use one, myself). For a mobile or cell phone, there are other options. You could use a solar power panel (I own a calculator that runs on a small solar panel; calculators don't use a lot of power, they use much less than phones do) or a muscle powered generator that you crank by hand (there exist radios that work by means of a crank). However, if your phone is not built to work that way, it will be difficult to retrofit it to work differently. Tell Apple that you want them to make a solar powered phone for you. But remember, solar power has its limits. You get no solar power at night, for example. A hybrid system, which still uses a battery but which recharges the battery by means of solar power, is more practical.
