Battery life (Solus Budgie)

computerilliterate

Hello,

I've been using Solus Budgie as my secondary OS for about a month now. Since I like both Solus and Budgie so much (and find myself spending a growing amount of time with them), I've installed it on a second laptop a few days ago (if it matters, it's a thinkpad x250 with the smallest external battery).

What simple programs can I install to maximize battery life? Should I be running tlp or powertop? I've read somewhere that running both at the same time isn't a good idea. Do I just download one of them from the Software Center and that's it or do I have to set it up somehow?

I've had Solus Budgie installed in other laptop and battery life wasn't that great. I've also had Elementary OS installed in that laptop (before installing Solus) and with Solus battery life was only about half of what it was with Elementary OS. But I don't know if this remains the case with this laptop since it has only ran Solus; I might be getting the most out of it already.

I'm unsure if this is the right topic for this post; I'm sorry if it isn't. I've seen this thread (https://discuss.getsol.us/d/73-what-are-your-favorite-battery-saving-tweaks-on-solus/9) but i was looking for something easier than what is discussed there.

Thank you for taking the time to read this.

Don't install TLP and PowerTOP together that will for sure cause problems and will certainly not give any significant power saving.

XerXes

Have a good ad-blocker like Ublock Origin installed and configured or use an ad-block hosts file at least:

https://github.com/StevenBlack/hosts

Browsers are the biggest power users, and loading ads and trackers is the biggest battery drain by far IMO.

I dunno if Linux kernel 5.0 will bring some power saving improvements or that Gnome 3.30 will improve it, but I hope so.

Thank you, kyrios and XerXes, for your help.

@kyrios Between tlp and powertop, which one do you recommend?

@XerXes I only use Adblock Plus for the browser. Is it significantly worse than what you recommended?

XerXes

Adblock plus is much heavier on CPU cycles and RAM. Ublock Origin is light as a feather and much more powerful, plus it's open source and does not have "paid ads" policy. With Advanced mode dynamic filtering it's a lot more flexible too.

computerilliterate Tbqf, I don't know. I see many people using TLP and some getting problems because they don't understand/check what the tool exactly do. You may get problem with PowerTOP as well I guess, but for me it just works fine in "autotune" mode (I added a systemd service for this last time I updated the package so all you have to do is to run sudo systemctl enable powertop.service to enable it at boot time. Do not forget to execute sudo powertop --calibrate before enablng the service.

I might be wrong but TLP have some unique options for Thinkpads (such as fan speed management) as it was originally made for them.

kyrios On desktops I've seen --auto-tune likes to disable also mouse movement

computerilliterate

Thank you all for your help.

@XerXes I'll follow your advice and switch from Adblock Plus to Ublock Origin, thank you.

Given what @Skyeun said about the connection between thinkpads and tlp, I might try it before powertop, but thank you @kyrios for suggesting how to configure it.

Searching online how to configure tlp I found that I should run "sudo systemctl enable tlp.service" and "sudo systemctl start tlp.service". Would this be enough?

On a general note, it is quite pleasing to see that the new Solus forum is as helpful as the previous one.

abdulocracy

TLP is a piece of software which automatically or optionally enables pretty much all of the powertop options, and has many more features to boot. I would recommend TLP.

To enable TLP, just execute the command it tells you about when you run sudo tlp stat. After that, you might want to install any extra packages that aid TLP in its various functionalities, I find that hdparm, smartmontools and ethtool are helpful. If you would like the ThinkPad-specific functionality, that requires either or both of 2 out-of-tree kernel modules not included in Solus. I might write up a guide on how to build them if you're interested.

For configuration it is best to understand what you are doing, so either leave it at default or follow the documentation.

When configured, I find that TLP quite significantly improves battery life on laptops. One issue I have had was when the HDD spindown setting was causing my HDD to constantly park on one of my machines, but I got it solved by tweaking the setting in the config.

Hi abdulocracy,

Thank you for your thoughtful and thorough reply.

I kind of jumped the gun and ran "sudo systemctl enable tlp.service" and "sudo systemctl start tlp.service" because they appeared to be frequently recommended when I searched online how to configure tlp. Should I undue this?

I'm pasting the output of running "sudo tlp stat bellow" (I'm sorry for how long it is). Based on it, should I run "sudo systemctl enable tlp-sleep.service" and "sudo systemctl mask systemd-rfkill.service"?

I'll follow your advice and install the extra packages you mentioned.

Given what both you and @kyrios said, I think that for my use-case it's best if I leave tlp in default configuration or I'll probably break something...

I have a SSD so I suppose that your problem with the HDD does not apply to my case.

Thank you very much for your willingness to write a guide for thinkpad-specific functionalities.

Browsing through the documentation to which you linked and through the tlp entry at Arch wiki, the only thinkpad-specific functionality I find is the battery thresholds configuration. Does configuring them make much of a difference? If not, I think I'll pass (at least for for now).

But maybe the guide would be helpful to other Solus users in the same situation?

Hi,

After running TLP for 2 weeks I don't notice any improvement on battery life.

I'm still getting only around 2 hours doing light stuff (one or two documents open in Libreoffice Writer and two or three tabs in Firefox; or watching videos using VLC).

Since this thinkpad x250 has the smallest external battery, and both the internal and the external batteries only have around 2/3 of their original capacity, I'm thinking this might be the most I can get.

Nonetheless, I'm going to try running Powertop instead of TLP . I want to be sure that TLP is correctly uninstalled before installing Powertop. Would a kind soul tell me how to do this?

Is it enough to run "sudo eopkg remove tlp" (or do the same through the Software Center) and then install Powertop?

Should I also uninstall hdparm, smartmontools, and ethtool?

And will simply removing tlp undo all tlp configurations? It would be logical for this to be the case, but I'd rather be sure.

This is what I did after installing TLP (at least, it's what I remember doing...):

sudo systemctl enable tlp.service

sudo systemctl start tlp.service

sudo systemctl enable tlp-sleep.service

sudo systemctl start tlp-sleep.service

sudo systemctl mask systemd-rfkill.service

and I installed the abovementioned packages that @abdulocracy recommended.

On a side note, the laptop's fan has been spinning like crazy (4000 to 5000 rpm) with just the use I described above. This started around the same time that I installed TLP. I cannot fathom how these issues could be related, but can they be or is it just a weird coincidence?

Thank you for your patience with my computer ineptitude.
