@daringfireball The other question to ask is: how often do you need 100% capacity battery? If you go to bed at <20% everyday, then yeah, charge to 100%. If not, then 80% is fine, or maybe don’t charge overnight and charge as needed, which is what I do. I only charge to 100% when I have plans to go out and about (or when I forget to take it off the charger).
