I don't think a valid test can really be done here for at least three reasons:

1) Radio version has a large effect on battery life, so the number of permutations (at least 7 radios to test with each ROM) means an unmanageable set of tests.

2) Just as with radios, geographic location, signal strength, roaming, etc. may affect battery life with different ROMs. This means that a ROM could have different battery life with the same radio in different locations.

3) People use these devices in very different ways. Battery life can be optimized for primary use as a telephone, as an organizer, as a music player, for frequent or constant data access, etc., etc. Best battery life for you and best for me (all other things such as radio and location being equal) may very well not be the same.
