Hello. My question is pretty much what the title asks. For those of you how have the 2017 13" MacBook Pro (i5/8GB/256GB) w/TouchBar, how is the battery life, compared to the 2016 version? On a side note: Will a hard case prevent proper heat dissipation or anything? I am going to search and go through the case thread, but I thought I would ask here, too. Thank you in advance for your help.
