My battery didn’t last as long as I expected. What can I do to extend battery life?

Exposing your battery to extreme temperatures—below -10°C (14°F) or above 45°C (113°F)—can shorten
battery life. Batteries are especially sensitive to high temperature extremes. As a good rule, always take
your phone with you when you leave your car.
