You definitely need to either wait for kernel 5.4rc1 for the idle power
consumption thingy to be fixed or if you use Archlinux you can use this
solution for now: <a href="https://bbs.archlinux.org/viewtopic.php?pid=1865600#p1865600">https://bbs.archlinux.org/viewtopic.php?pid=1865600#p1865600</a>
Or you compile this kernel source on your own:

Kernel 5.3 has a fixed setting for idle power consumption. I haven't found any
way to reduce idle power consumption with this kernel version.</pre>
