Only using EV Mode between 20% and 80%

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.

Hm, I have never thought about it that way. It is hard to admit, but I think you are right. I supposed we can't leave the battery to go to 0% to use at least 80% of it...lol

While I have read many articles about the 80 / 20 rule of Battery charging, I do not think it applies to the A3 using the supplied Audi charger. There is no setting for limiting charge that I am aware of. I have my Audi charger mounted on the wall of my garage plug into a 240 volt line. When the A3 Battery range gets below 8 miles or so, I plug in and using the 240 volt setting (Audi sets the Charge to 50% rate) I see a 2+ hour recharge to the full (?) range of 24 miles.
I have never charged the A3 at a public Charger so I assume they might give me the option to limit to 80% - but why would I do that and perhaps cut my range by 20%? I know that the A3 never fully discharges as the switch to Hybrid is automatic when the remailing mile range show 0 - but the A3 still has reserve charge to continue the Stop state function for a long time. I took a round trip in heavy traffic of 100 miles. The charge showed 0 after about 18 miles of this drive. 3 passengers and lights and A/C on. The start stop and hybrid mode continued to work till we returned home. And the recharge time was about 2.5 hours. I do not know how far you drive in Hybrid and still have some EV battery left -but I would hope the Audi System wool warn you that you "Must Stop and Recharge" - because without the HV battery you have no Starter motor! Maybe when the Gas tank is almost empty (350 miles or so) a warning will require a Fill-up with Gas and Volts???
