Hey guys, just received my rMBP 15' refurb a couple days ago and I noticed some things. 1) If I were using it on my lap or bed and watching youtube videos in 1080p, is it supposed to get pretty-very warm? Also, when I'm charging the laptop the magnetic part of the charger that sticks into the laptop is almost untouchably hot. Is that normal? 2) Is it normal to have 3-4 hrs of battery life when watching youtube videos? With brightness at 50% I don't seem to get anything over 4-5 hours with normal usage.
