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?

Answer 1

The 0-100% that is shown to the user in reality is 10-90%~ actual capacity in the battery.

So when your phone goes 0% battery, physically there is still juice left in the battery.
