tick_sched_timer is by far the “process” at the top of powertop which consumes most energy. At those occasions when I have checked the energy consumption could be anything between 2.5 to 5 W. Is this normal? Are there any optimal settings/configuration to reduce it’s power consumption? I have tried to search and come up with some info that it is related to CPU wake-ups but not much beyond that. This is what I have have under WakeUp tab in powertop:
PowerTOP 2.13 Overview Idle stats Frequency stats Device stats Tunables WakeUp
>> Enabled Wake-on-lan status for device enp1s0
Disabled Wake-on-lan status for device wlan0
Disabled Wake status for USB device 1-7
Disabled Wake status for USB device usb1
Disabled Wake status for USB device usb2
The thing is that sadly enough the battery on this laptop deteriorated quite rapidly just within a couple of months after the purchase. So whenever it is on battery, I am on my toes. I’ll take your advice and switch to the normal linux kernel and see if I get better battery life.
I have been here for a short time. But what I have seen from your input, the above is an exaggerated understatement.
