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.
