1. 80% Charge and Extreme Temperatures
Do not let the iPhone’s battery reach zero or 100%. Do not, also, charge the iPhone past 80%. 80% charge is ideal for the battery’s health. The health of the battery diminishes every time you complete a charge cycle.
Regarding extreme temperatures, your device is designed to perform within a certain temperature range. If you expose your iPhone to an ambient temperature that is higher than 95° F (35° C), it can permanently damage the capacity of the battery.
