watching Wh - (track power usage on the MBP)

[Gaura Mohana]

hi
i'm wondering wether there is a way to track power usage on the MBP
coconut battery simply tells me xxW per hour
what i'd like to know is precisely what is taking that much per hour?

if no can anyone tell me what takes the most? with no USB devices plugged in, brightness less then half, on keylights, etc i managed to get down to 7.4
doesnt 10 hours mean 6.3Wh?

Well yes 10h meand 6.3 W or less.
The only thing I know of is reaching the lowest and than turn on and off stuff and see what changes. Usually one has to wait a little till it reports a constant discharge rate.
The lowest I can get is 7.3W with my 15" but that is the absolute best case scenario. Othertimes it reports very different numbers and just constantly is 1-2 W higher with the very same load, which is to say close to none.
It would be really nice to know what's going wrong sometimes or if it is just that the battery is sometimes a little off with the reported discharge rates.
