Something quite related has been discussed in Google groups not too long ago. You can find the full thread here for reference.

A small excerpt from the last reply in that thread, which should answer your question more or less:

(...) the battery capacity is always given in terms of mAH. (...) What matters is how long a battery can supply a given current at its rated voltage. 3800mAH means that it can supply 3800mA for 1 hour. Knowing this it makes sense now that the API is providing the current drain as a metric of power consumption. You can now calculate how much effect it will have on the battery life as a function of time.
