I agree which is why I have a dead Apple iPad one out in the garden.
Age related but it had been looked after by one careful owner (not me). I took it away from them during lockdown because I knew it was a potential fire hazard. My wife's previous iPhone 5? had a serious battery fault too with a free manufacturers replacement as a result.
Yes it is a bad idea. There is some setting in the BIOS of the some of the recent Dells to change that so that it doesn't charge to 100% all the time, but watch out. There is a setting something like "Primarily AC use" that seems to not work properly, in that it still charges it to
100%. There are complaints in the forums that this seems inappropriate and that you need to configure your own custom settings (which it lets you do in the BIOS too).
On the other hand, it is optimistic to expect the company that designs the charger but also sells the replacements for any failed batteries to go out of their way to increase the battery life beyond what is necessary to avoid failures during the warranty period. There is a short-term financial incentive to allow the batteries to fail not long after the end of the warranty, and a reputational incentive to make them last a long time. Depending on the company's management style and the ethics of the engineers, the results could vary.

There is also the issue of keeping the battery charged so the user gets max imum battery time when not plugged in. Combine that with the desire to rat e the batteries as high as possible for advertising purposes and you get ba tteries that are more sensitive to being fully (over) charged on a regular basis.
My Lenovo would warn me periodically that I should not leave the battery on full charge as if draining it enough to turn off the warning would do anyt hing to prolong the battery life. The real problem is putting the full ch arge on in the first place when it is not needed. The really hard part is knowing when the 100% charge will be needed and making sure the battery has a full charge at that time.
Bottom line is that batteries suck.

I think Apple has or tried some learning algorithm that attempted to predic t when you needed the full change, like in the morning when leaving for wor k, but not when you plug it in coming home and not leaving until next morning
they suck a lot less than they used to
I was hoping to find some sort of an external charge regulator to maybe keep the charge of my MacBook somewhere in the middle. Let's say 25 to 75% charged. No luck but maybe it wasn't such a good idea anyhow. I stumbled across an article about the MacBook Pros. Plug the chargers into the right side if there are ports on that side. They can get hot if the charger is plugged into the left side. It's something about kernels, whatever those are.
