How I DOUBLED my battery life on Arch Linux

Linux is infamous for a lot of things, but one thing it's infamous in is battery life. This video will show how I doubled my battery life on Arch Linux, and how you can too!

mans didn't make it one minute before mentioning he uses arch

Some more tricks:

tlp also be used to control the cpu in addition to different devices (usb, bluetooth, wifi, etc.). HOWEVER, if you want to use tlp and auto-cpufreq together then don't add any config options to tlp telling tlp to manage the cpu (you can have tlp only manage devices). Otherwise tlp and auto-cpufreq will be fighting and your laptop will not have fun.

powertop is like htop, but instead of showing resource usage it shows power usage. You can use the command `sudo powertop --calibrate` (does weird stuff for a few minutes) followed by `sudo powertop --auto-tune`. Calibrating will have powertop go through a bunch of settings to figure out which will save the most power. Auto-tune enables these calibrated settings. I'm not sure if powertop manages devices and the cpu or just devices, so read documentation or search the internet if you want to use it alongside tlp or auto-cpufreq. I think powertop also gives you the most battery life (maybe there's a better way I don't know), but at the cost of convenience (usb goes to sleep after inactivity, etc.).

Guy is rubbing arch linux every 30 seconds on our face

Good video. I got 30 minutes of extra battery life from using Gentoo over Arch. Turns out this difference is caused by using a custom kernel configuration (which can indeed be done on Arch or any other distribution). If you really need more battery life, consider writing a custom kernel configuration.

i think one of the best think about older laptops there is that you can have two full charged batteries with you, and swap when needed

I would also like to add checking whether the igpu's drivers are installed as it helps a ton for video content as software decoding uses lots of power

[arcstur]

Thank you so much. The screen refresh rate alone already helped a lot.

How is optimus only available on arch linux but comes with pop os as default? Honestly, makes no sense to me.

I used zorin
And auto config doesn't work on hp omen Nvidia GeForce GTX

Even without a GUI, and with the lid closed, my PC uses around 8w (i used ssh to find out), do you have any idea why?

Here is a better steps to improve battery life.
1. Switch to MATE as the desktop not KDE/GNOME/XFCE/LXQT. Because MATE is the oldest and the most stable code base without any bloat or "back ground running tasks". Nothing is running on MATE when the user is doing nothing.
2. Install TLP from the the app store. Then install TLP-UI to configure the power setting of everything on the machine. CPU/GPU/PCIE/USB/DISK. this is a onestop solution. Just remember to not have power-profiles-daemon along with this, they donot play well with each other overriding each other.
3. Reduce refresh rate to as low as you can go. Display brightness is your choice just know brightness power is not linear.
That is it.

I always have problem related to my battery life. It's works for only 45 minutes or less, which is literally no acceptable.

Although I use less than 5 % of brightness, and implemented other saving ways but it's not working. Sed😢

On a completely different note, running Arch, with a Vista wallpaper and having Mac windows animations is crazy. 😂

envy control for disabling gpu on fedora with hyprland works fine!

1:20 mine was 8 and a half hours

we learned nothing and the days went into 9 hours.

[joaopauloalbq]

Are you using hardware video acceleration on Brave? Firefox has hardware video acceleration by default and improve battery life a lot!

Nice vid 👍, in my case for my gaming laptop a clevo notebook model p65_67 i use tuxedo control which pretty much gives close to full control to fan curve on gpu and cpu and underclocking the cpu to help out, it also helps out on temps quite a bit, and supergfxctl to switch between gpu's, not the best, i wish i could get full acpi call similiar to windows working but does the job, still. As for battery well in my case at most an hour but i think in this case is more of an hw problem as on windows it pretty much does not work.

[krishnabillonaire]

auto cpu-freq makes my system so leggy and choppy
any solution for that?

[sourcey]

this really helped alot on my system. Thanks alot !

[hana-gabana]

TY!!!. after installing optimus manager i got a boot loop. had to reinstall the system, try again and after getting another boot loop, i uninstalled it via Ctrl+Alt+f2. that solves the problem for me
