Recently I noticed that my laptops battery is very worse so I checked powertop for the power consumption. Doesn't matter what I do. The the top processes are 

Radio device: btusb
tick_sched_time

Together they consume almost 15-17 W of power.

What are these services and how can I fix this issue. My laptop is a Precision 5530 from Dell.

If you are not using bluetooth (higher power consumption) you can simply turn it off.

To turn off bluetooth only temporarily, use rfkill:

$ sudo rfkill block bluetooth

To permanently turn off bluetooth create a udev rule:

$ sudo -H gedit /etc/udev/rules.d/50-bluetooth.rules

Then in the empty file, insert these lines:

# disable bluetooth
SUBSYSTEM=="rfkill", ATTR{type}=="bluetooth", ATTR{state}="0"

Save the file and exist.

    Thanks for the help. I usually use Bluetooth for my mouse, so disabling it completely is not an option. Might there be something wrong with the driver? Do you also have a solution for the tick_sched_timer? – SnowGepard Mar 18 '20 at 7:01

    Killing the process helped, but it is not a good solution in my case since I really depend on bluetooth. Is there an option to figure out what is actually wrong with the process and maybe reinstall the package in a safe way. – SnowGepard Mar 23 '20 at 15:27
