I still question the notion that this is a good idea. If you do not fully charge your battery it doesn't last as long, so you end up charging it more often. *That* (how often it's charged) is not good for battery life. And it's also a pain for the user, in that your device may not run for as long as you need it to. And that's certainly a case for some devices like phones, where you end having to recharge it during the day, rather than having one charge last for the entire day, or longer. For example, my phone's 7 years old, with a sealed-in battery. I've never done that 80% thing, and always allowed it to fast charge (which is something it only actually does with a very empty battery - the charging once it fills up beyond a certain point is slow charging). It has done well for everything but the last year, before that lasting the whole day or several (when it's mostly idle being ignored by me) only suffering, recently, from being charged again and again, thanks to my computer being tethered to it for the internet (it charges, runs down a bit, charges, etc). There doesn't seem to be any smarts that when running from external power it should charge the battery, stop, then stop using the battery for power and run solely from the external supply. Likewise, my laptop's battery suffered from being operated most of the time while plugged into the mains. I don't think I got three years out of it before it went totally kaput. It was getting really bad, to the point where the battery only lasted long enough to unplug, move to a different spot, then plug back in again. Then I made the mistake of letting the laptop's BIOS firmware do a battery recalibration, and it completely killed it instantly. I'd only go on a battery preserving mission if your battery is sealed in and hard to swap. And even then I really do not believe the fad. Go for maximum personal convenience. Most things do so-called smart charging. They only do high-current charging on a very flat battery to bring things back to being somewhat usable quickly. They reduce charging current beyond a certain point, which they've determined through supposedly expert electronics engineering, to finish charging more slowly. And thermal monitoring is involved as another hold back against overdoing things while charging. My background is in electronics, by the way. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
