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

There is. It’s just not something shown to the user. Margins for what is 90% are changed in the settings. Your 100% charge capacity may or may not already be at that 90% total capacity, depending on manufacturer.
