How to charge a dead cell phone without a charger

Updated February 21, 2017

If your cell phone battery dies and you don't have your charger to plug into an electrical socket, you may still be able to power up the phone by connecting to a computer or laptop with a USB cable. Many cell phones are equipped with a mini-USB port to connect to a computer either for data transfers or to recharge the battery.

Press the power or "End" button on the cell phone to turn off the unit. It will charger faster if it's not running.

Connect the mini-USB plug on the cable that comes with your phone to the port along one edge of your device. Remove the port cover, if necessary, by slipping a fingernail under the lip of the cover so it will pop off.

Insert the other end of the cable into a USB port on the computer. Don't use a port on a keyboard or other external device; they may not deliver enough power to charge the phone.


Recharge times vary by phone model.
