Hi Everyone, long time reader, first time poster. I picked up a SP3 i5 256gb last weekend and have been really enjoying it. Last night I decided to hook it up to my TV and play some XCOM: EW. With the help of the USB fan that others have posted, I was able to play at 720 with medium/low settings (looked great...still working on getting Steam InHome Streaming to work from my rig). Anyway, after a 2-3 hour session, I picked up the SP3 (was cool to the touch!) and noticed that my battery had actually been drained to about 15%, although I was plugged in. I'll need to test it out again later this week, but curious if anyone else has had a similar experience?
