Against my better judgement, I decided to order the new 2016 rMBP to see if it could replace my 2012 rMBP 15. The battery life so far has been sub par (shorter than a colleague's 2015 rMBP 15's battery life with iGPU only) getting only 4-5 hours which is what my 4 year old 2012 rMBP was getting. It feels just a smidgen faster than my 2012 rMBP 15. What I'm noticing is that my laptop will stay on periodically with the cover closed and on battery power instead of going into sleep mode. Sometimes it will drain the battery by at least 50% and get very hot as it's running in a laptop bag. No other apps other than Safari are running, power nap is off so I don't know what gives. Anyone else with the same problem?
