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?

These batteries come with safeties already built in to prevent damage and increase battery life-span.
The 100% it tells you is not actually 100%, it’s closer to 90%.
The 0% it tells you is closer to 5%. Proof: if your phone dies, try turning it back on. The screen will light up to tell you there is no battery.
There have been other improvements done to batteries over the years too, like how they charge. Instead of having the power supply in the phone, they instead put it in the power bricks you plug into the wall. This keeps the heat away from the battery.
If you’re wondering why “my phone from 6 years ago lasted me around the same amount of time that my current phone lasts me”, it’s because your newer phone has newer tech that is more power hungry. A faster phone with a nicer screen means more battery drain.
