I'm wondering if there are any issues of having a macbook pro connected to a 4k monitor in clamshell mode 95% of the time? The first concern is heat and ventilation related. I noticed on my MBP 15" 2015, it heats up and I can feel some heat on the keyboard area. We all know heat is a destroyer when it comes to computers. So if I plan to use it in clamshell mode, almost 100% of the time, wouldn't this heat accumulate facing the retina screen, potentially causing some harm/damage over time? At the same time this would disrupt better cooling of the computer and decrease its life span? The second concern is battery. If it's always plugged in and the battery is not being used, will any issues arise after a while? I read that some people discharge it to 35% every two weeks just to keep the battery healthy. Is that frequency sufficient enough to keep the battery life optimal? My goal is to keep the computer optimally maintained for a prolonged lifespan.
