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?

So oppositely its bad for lithium batteries to be fully drained. Just a number im gonna pull out of my ass because google takes too much time: Lets asume the lower limit is 20% charge and upper limit is 90%. You want your phone to opperate in that range 20-90% which is a total of 70% of the max capacity.

So you set your lower limit 20% to be equal to no charge “0%” and define 90% to be equal 100%.

Thats what your phone shows on the top right. Not the actual percentage of capacity but the operating capacity.
