What's the point of having a popping cpu/gpu, screen and 12 gb of ram if it's fucking off :guaido-despair:
PLEASE do what the Chinese phones does and shove batteries down my throat

If you can stand the idea of only charging your laptop to roughly 85%, then I highly recommend trying that. I've had my laptop for like 3 years now and haven't noticed any decrease in battery life. I'm also a huge stickler about brightness, and programs running in the background. With laptops being so power efficient anyways, I can still get a good day's use out of 85% anyways, and that's only going to get better with time.
I'm planning on doing this with my next phone, and other lithium ion stuff I own too.
Also don't let it drop below 30%
Yes, from a chemistry perspective this is because the lithium ions in the battery basically work by moving ions between the lithium and other cells inside the battery, which powers the laptop, then by charging it it moves the ions back to the other side. However, overcharging or letting it get too low can cause buildups of some free ions (pretty sure) that severely hamper the ability of the lithium ions to return, decreasing the battery life. Lithium is the best material for the job as it loves donating ions to the anode (I think, might be cathode) since it’s unstable, but research is being done into sodium batteries as they’re extremely environmentally friendly and they don’t explode, although they’re orders of magnitude less efficient.
Wouldn’t this this be taken into account by a competent OS/whoever is in charge of telling the computer about the status of the battery? That is, if 30-85% were the optimal range, I would simply force the computer to operate in those ranges; go dead at 30% for example (and calibrate the battery life display accordingly).
Certainly the lower limit is limited, maybe not the upper limit. At least, my dumb e-cigs know not to discharge 18650s (which I believe were pretty common a few years ago in laptop battery packs) below 3.0V, although my charger is not smart enough to keep it below 4V or anything.
I guess you would need to lower on “x hour” battery claims if you did this, which is probably not desirable. And stuff isn’t really built to last.
So I guess I’ve talked myself out of believing this could ever be a native manufacturer/OS thing.
Lenovo has an option to only charge your laptop to a specified maximum percentage in the Lenovo Vantage program. I think other manufacturers are starting to implement this as well. I'm not sure how this could be done on Linux, but if there's a driver for the power management firmware it should be possible.
