14 Ways To Double Your iPhone’s Battery Life
Turn AirDrop Off
Making its debut in iOS 7, AirDrop makes it easy to send pictures, contacts, memos, locations, and more with nearby devices. AirDrop uses both Wi-Fi and Bluetooth to make this possible, which both drain the iPhone battery. When you’re not actively using it, turn it off. Just pull up the Control Center, tap AirDrop, then select Off.
