normally we budget about 5 watts per phone max, less in standby
polycom has a good list here:

but your phone vendor should have a list – since large installations need to know how much power to budget – in a 1000 phone network, 5000 watts or 15000 watts is a big difference.
hence the “15.3 watt” spec of 802.3af is not very helpful
