Two unconventional things I do to improve my iPhone's battery health (which follow this article's findings): 1) Don't use a case - Otherwise, you are literally wrapping your phone in a rubber insulator 24/7, increasing its overall temperature. 2) Don't charge at night - Turn off your phone at night. Instead, charge it during the day when you're at your desk. This reduces the number of cycles over years (because your phone is continually draining/recharging all night even when you aren't using it)
