Make sure you use a compatible USB charger to charge your phone.
- First connect the USB cable to the charger, and plug the charger into a wall outlet, then connect the micro-USB end of the cable to your phone.
- When the battery is full, disconnect the charger from the
phone, then from the wall outlet.

If your phone is off when you start charging, it automatically switches on.

You can use USB charging when a wall outlet is not available. Data can be transferred while charging the device. The efficiency of USB charging power varies significantly, and it may take a long time for charging to start and the device to start functioning.
