Say you’ve got 15 minutes in an airport between flights and your phone is nearly dead. What do you do?
In the past, you had two choices. You could give it the old college try: find an outlet and plug in your phone, watch the battery meter inch up as the minutes run down, and pray that you’ve gained enough power to get you through your day. Or you admit defeat and let your phone die. In 15 minutes of charging, you’re only going to get a few percent more battery power anyway.
