Your device manufacturer has designed it to break in as many ways as possible so you have to buy a new one.

Why do you think everyone switched to non-removable batteries?

If you don't take responsibility for your device, you are just like the people that think not owning your own hardware is fine.

Samsung phones have the capability to do this. There's a setting you can set to only charge to 80%. It looks like they mention that in the article.

Android phones in general have something called Adaptive Charging that attunes to when you normally need a full charge. For instance if you are charging at night while you're sleeping it will charge slower than it would during the day to improve battery health.

100% agree. Mate, there's an another ongoing post on lemmy about autosaving documents, and how everyone seems to think that saving files with their fingers pressing keys on a keyboard is the best approach possible in 2024 because software just can't do this reliably.

Of course everyone also knows better than their charger, battery and device.

Yup. If it’s such a huge issue, phones should only charge to 80% and report that to the user as 100%. But phone manufacturers won’t do that, because users want to be able to report the longest battery life possible when selling new phones. They don’t care that the charging habits are bad for battery longevity, because the user has already purchased the phone.

No, it's your problem.

The manufacturers correctly surmise that most people prefer a battery that holds it's charge longer over the first year or so, rather than a battery that will last more years.

If your preferences differ from that of most people, then you need to exercise your preferences.

When you say "make it do x and y" who should be the person that does it? Without raising enough awareness of the problem, change will not happen. The only way for it to happen is that enough people is pissed off and changes brands.
