Hello,
It seems that my power consumption is significantly higher after resuming from a suspend than before. I suspend with the systemctl command. Measuring the battery usage (with powertop or looking at /sys/class/power_supply/BAT0/power_now on my laptop), I get the following numbers :
- 6-7 W before suspend
- 10-11 W after
Those number are quite stable in time, in particular the higher consumption stays until shutdown. I have tried looking at the power decomposition of powertop, and it seems that the backlight display consumption is indeed higher, although I keep the same luminosity level. I tend to consider the decomposition usage by powertop as a guess estimate anyway, so I am not sure whether this means anything.
Any ideas on how to solve this issue, or how to investigate further on?
Cheers,
Guillaume

Any idea about where I should post this question, maybe?
I'd be grateful for any answer, thanks.

Have a look at powertop before and after suspend. I noticed that some power saving options get turned off when suspending. I don't have a solution though.
