Public bug reported:
I have high battery drain during sleep with my Dell XPS 9320. It drains
fast when I boot into kernel 6.2 (linux-image-6.2.0-32-generic) but not
when I boot into kernel 6.0 (linux-image-6.0.0-1020-oem).
I took these measurements:
- Kernel 6.0: suspended for 11 hours from a full charge - 6% battery drain
- Kernel 6.2: suspended for 6.5 hours from a full charge - 27% battery drain
I'm using the latest BIOS version for my laptop (2.5.0). I'm on Ubuntu
22.04.
I'm attaching two syslog excerpts of suspend/resume cycles on both kernels
(they are from the suspend/resume when I took the measurements).
