How do I maintain the charging efficiency on my Audi e-Tron?

I recently purchased an Audi e-Tron and was wondering what steps I can take to ensure the charging efficiency remains optimal for the long term.

Regularly clean and inspect the charging port for any debris or buildup. This can greatly affect the efficiency of charging.

Invest in a level 2 charger for faster and more efficient charging at home. It may seem like a big expense upfront, but it will save you time and money in the long run.
