Various things have different default behavior when not plugged in to the power (e.g. iTerm2 disables GPU rendering by default). This is just the one place I know that's a counterpoint (and there's a setting to disable that), but it's actually something that I've hit a few times while developing Ratatui.
Earlier quoted context omitted.
It does, if the battery is 100% no more charging current goes in, so charging stops. But the key point is that the battery will drop to 99% very quickly and on it's own because no battery can keep the energy in perfectly. So it's recharged for the missing 1% over and over again which causes the damage. Unless some smart charging logic prevents that, see other comments here. Edit: typo
It's not just this, it's literally bad to keep a lithium ion battery in a high voltage state, period. Simply taking a battery out and leaving it on the shelf in a high voltage state, otherwise unused, harms it.
However, keeping "a lot" of energy in the battery is kind of the purpose, no one is using 50% max to increase battery life. But I guess most damage increases exponentially with energy stored, so charging it from 95% to 100% will damage it a lot more to than charging it from 90% to 95%.
Apple took this out of Mac OS somewhat recently. You can try to rely on their power management, but given battery decay is a common reason to buy a new machine I don’t trust them really. If you have an Apple Silicon Mac I can recommend Battery [1]. It can keep your Mac at 80%, and even force discharge while plugged in to get there. It’s a CLI and status bar utility, I love it.

If you have a highly irregular schedule, then sure, this may not be helpful. But I find that my and my wife's Apple Silicon laptops are usually kept at 80% unless we explicitly tell them to "charge to full now".
Why not to implement a feature on all OSs that stops charging your battery once it gets at 100% and start the charging again at about 50%? It's healthy for the battery (aka it doesn't degrade it if it doesn't charge) and it's not letting you remain at 10% - from where it goes instantly at 0%. The dingus remains at how to make it happen, even if i've seen it getting into iOS and Android.
The article's advice isn't the best. It's better to not cycle your battery whenever possible. Set your battery up to only charge when bellow a certain threshold (I do 70%) lower than the max charge (I have it set to 80%). This optimises for not over straining the battery (by not going to 100%) and it reducing cycles to a minimum for my everyday use only travelling between (desk) locations. I set this up through the p…
Even worse, unplugging your laptop makes it use battery charge, adding additional wear to your battery.
Virtually all EV's have good software, so your electric car should be plugged into a charger as often as possible. It should be the same for laptops, unless you have one that is poorly configured; most are.

...took what out of macOS? It definitely still does "smart charging", keeping it at 80% until just before when it has learned you are likely to unplug it. If you have a highly irregular schedule, then sure, this may not be helpful. But I find that my and my wife's Apple Silicon laptops are usually kept at 80% unless we explicitly tell them to "charge to full now".
Is there a good reason why we can't tell our devices to charge the battery to say 70% and then internally disconnect the battery, so it's neither charging nor discharging?
Dell laptops have had such a feature literally for a decade now
