Only using EV Mode between 20% and 80%

[David NZ]

Hi I could not find this on searching. Apologies if I missed one.
I’ve read that best to keep EV battery between 20% and 80% to maximise its life. Is this meaning only charge to 80% on the gauge and then change to hold mode at 20%? So that gives you only 60% of range to use.
I get 37km (19miles) from my car from a full charge till it turns off EV in NZ, so 60% gives me only 22km (11.5 miles). Or is empty not empty and full not full in regard to actual battery charge?
Sorry about the convoluted question.

I only charge mine to 100% only if I have a long ride.
