My Thinkpad T480s randomly dies with Arch Linux

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Are you using battery thresholds and keeping your laptop connected? There is a bug in ThinkPads, at least with my t480, in which the batteries get discharged over time but doesn't get reported which causes the sudden power off. If you are using TLP I suggest you to either force a full charge or a recalibration to charge your battery properly. Also don't discard the possibility of having a broken battery.
