Best kernel for battery AND performance? : r/archlinux

I have tried lts kernel, 5.5 and the new one 5.6 LTS (5.4) was very bad. It used more than 4W on idle. 5.5 used 3,05W and 5.6 uses 3,3W now. I did not change anything on the os.Only installed tlp, powertop and deactivated dgpu. Tested them on a fresh install. Edit: I dont know why, but 5.6 uses 3,1W now.

Is there a way to change the maximum percentage my battery can

Hardware support of battery charge limiting is needed and every manufacturer does it differently. Some hardware is actually hard limited so you can''t change it. It might need kernel support. I found mine in the EFI menus (Surface Book 2 15"), I can''t change it while booted.

Battery kernel 5400mah (Double battery) : r/RG35XX

I wanted to ask if there is any way to modify/get a kernel for a 5000 - 5400mah battery. I bought the battery as a good newbie, which I later saw here was a fake, and once I had it at home I confirmed it. So what I did was to add it to the original battery, so now it should have 2800mah X 2. See the attached picture of the mod.

Get the best out of you battery on linux : r/linux

9. Update your kernel to the latest stable version. Upgrading kernel will make your PC faster, safer, and have better compatibility with your Linux OS, and of course will bring some power-saving improvements. Linux Mint 19 is still on 4.15 (it''s pretty easy to change this in Ubuntu/Linux Mint though, I used ukuu for that).

Instead of installing several power optimization tools, I would suggest that you wait for the next version.

It is already in the official repositories, but the main drawback is that it doesn''t remember its state between reboots

Question

In kernel, battery-data is used to regulate the activity of battery usages in the device when active, idle, or when charging. Without these battery-data, the device will surely read the wrong input/output from the battery voltage that can cause damage to the device itself.
