I have yet to get over 2 hours on a fully charged battery.
$ cat /etc/modprobe.d/snd-hda-intel.conf

Enabling switchable graphics and installing bumblebee had a huge impact on battery life.
Function keys aren't automatically recognized. The xf86 keypresses are recognized by i3-wm which runs corresponding xbacklight commands.
$ cat ~/.i3/config
# Backlight bindsym XF86MonBrightnessUp exec xbacklight -inc 10 bindsym XF86MonBrightnessDown exec xbacklight -dec 10
$ cat /etc/sysctl.d/disable_watchdog.conf
kernel.nmi_watchdog = 0
$ cat /etc/sysctl.d/dirty_writeback.conf
vm.dirty_writeback_centisecs = 6000
$ cat /etc/sysctl.d/laptop.conf
vm.laptop_mode = 5
$ cat /etc/modprobe.d/iwlwifi.conf
options iwlwifi power_save=1 d0i3_disable=0 uapsd_disable=0
It looks like as of libinput 1.6.0 the trackpoint and touchpad are recognized separately. Unfortunately, the trackpoint is nearly unusable due to sensitivity issues.
Enabling an external monitor causes trouble because Xorg can only handle one DPI, and right now that's set to work with the hiDPI internal screen.
Activate the external monitor with arandr, if the gui is too large:
xrandr --output eDP-1 --auto --output HDMI-2 --auto --panning 3840x2160+3840+0 --scale 1.5x1.5 --right-of eDP-1
HiDPI / High DPI / Retina / 4k
The nitpicky details are on User:ctag/HiDPI.
