for max (lithium-ion) battery life, recharge often, keeping the battery level between ~40 and ~70%. deep cycling (e.g. charging fully to 100% and running it down to ~15%) wears the battery out faster. presumably, this applies to lithium-ion batteries used in EV's as well.Apple knows how to do good batteries, they just choose not too on their phones. I have an iPad Air 2 from 2014 that still holds a charge very well. My wifes old 6s, not so much.
