I always hear that it’s bad for lithium batteries to charge over 90% or over 90% so why is there no setting to stop charging after a certain threshold on my phone, kindle, pc or e-skate?

I have a Motorola g100 and there is a setting that only lets the phone charge to 80% on the charger except the 20 minutes before I get up in the morning, it then charges to 100%, What I read stated that it is not good to keep a lithium battery at 100% because the battery is stressed (I’m not sure what physics properties apply) while in a fully charge state.
If you are into building drones, you can learn the hard way: letting a battery go to zero or 100% will pretty much ruin the battery. That is why they ship at 50% charge, and should be stored that way. Some battery chargers have a stop-at setting, others will gladly go to 100%. Same with discharging: unless you have a heads-up display that tells you the battery charge %age, you can easily fly down to 0% and kill your battery. Non-custom drones have more protections built into their chargers and controllers (like DJI for example).
ELI5 why this happens is if the charge is too low, there aren’t enough electrons in the battery to conduct current; if the charge is too high, there are too many electrons and current can’t flow. That’s a radical oversimplification.
Samsung with android 12 has feature that let’s you lock charging only upto 85%. It won’t charge above 85% if enabled
