The high res screen (on an XPS 15, not 13) also drains the battery significantly. I opted for the "low res" 1920x1080 screen which works much better for my use

The high res screen (on an XPS 15, not 13) also drains the battery significantly. I opted for the "low res" 1920x1080 screen which works much better for my uses. I have an external 4k monitor when at a desk and a sufficient display when on the go. This is all with Debian Linux btw.
