Yup. This has been general knowledge for lithium ion batteries for a decade. Ideally, determine your daily battery use...say you need 40% of your capacity...then charge to 70%, and discharge to 30%, and you will obtain the maximum battery life. This has been stated publicly by every battery researcher, and corporate battery designer....even Elon Musk himself. Although he walked this back some for marketing reasons, as EV true believers don't want to hear about any limitations.

If Tesla's newly patented "million mile" battery pans out, in a few years, this will all be history, as will be most of his competitors.
