Thunderbolt Ethernet Adapter Draining Battery?

I noticed that Safari was listed as an app using signinficant power, even when only one tab was open on google... I thought this was strange because I had never noticed this before, however, it was also the first time I had used the thunderbolt ethernet adapter. Could this be the root of the problem? I have had issiues with the adapter, and it was recommended by an apple tech to do a SMC. The adapter and computer were getting very warm, and I tried doing the SMC today and it SEEMS to be better. I am currently on wi-fi and Safari is no longer listed as an app using significant power.

Thanks!

Are you using the Activity Monitor to monitor system usage?

I'm not sure.. I am selecting the power indicator (next to the percentage of battery left), which brings down a drop-down menu. It is located on the top right hand corner of the screen, on the top bar.

I am having a similar problem. When working on wifi I can run a whole day with power to spare on my MBA. Am at a different site today and using the Thunderbolt ethernet adapter and power is draining very rapidly. In my case Activity Monitor is showing IBM Notes as 21.87 Energy Impact but I don't think it's the application. I now have to go home to get my mains adapter.
