Best Distro for Laptops?

I want to know your opinions on the best distro that is convenient for laptops. Main reason is I want to really optimize hardware performance and more specifically battery life for my University classes. I also want to try a tiling manager as they seem perfect for laptops.

Things of note:

• Convenience/Performance is key
• My laptop is a Thinkpad E15 w/ 16 gb ram
• On my home desktop I run Archlinux w/ Open box & no DE (I've been using Arch for years but haven't used another distro since Ubuntu in highschool)
• I will likely dual boot with Windows 10 for Office
• I want to run a tiling manager
• I don't video game
• I wont be using a mouse
• I don't necessarily want to use Arch, want to try something new that I don't have to rely on AUR updates for certain software
