Macbook pro 15 2.3 late 2013 battery and temperature issue

Hi, this is the first time i bought an apple product ( the high end retina late 2013 ). As advertised on the website it should last 8 hours of web browsing and same for itunes movie playback. So to test it, I configured it to no auto brightness, 9/16 brightness, only 2 bars of keyboards backlit. I only used max of 4 chrome tabs and downloading with bitTorrent. I also watched 360p videos for like 45 minutes and system was also idle for like 30-60 minutes. It only lasted no more than 5 hours and 30 minutes -_-. Whats the point of haswell here ?

Temperature while idle (istat free) is around 35-40, light browsing 48-60(cpu 95 % idle), watching a 4k video leads to 70-80. Haven't tested any high end games yet. Palm rest gets a lil warm but the bottom gets hot. Fans speeds are 1900-2000 under normal use. Just played fifa 14 and the fan noise were trying to catch up usian bolt's record.

Can anyone tell me is this normal on new macbook pro models or should i call the apple store?

Thanks
