And you should note that in most cases, the reported watt usage is correct because the battery hardware is working properly.
In some cases the watt usage will be incorrect because your battery is borked. I've seen this happen.
If your battery drops from 100% to 60% within 15 minutes, there is almost certainly something wrong with the battery. Or you are running an Alienware. :-)

... or it's an old battery with correspondingly high internal resistance due to oxidation. (This generally exhibits itself as a battery with 'high' capacity that drops fast, in my experience.)
