The 1080P screen will get you the maximum battery life that you can get where the 1440p will likely cost you between 2-3 hours of battery to push the extra pixels. I recommend the 1080p screen for the average college student so they aren’t tethered to the wall between classes. 1440p if you just want to watch Netflix in its full glory.
