LG VOLT LS740 CHARGING BASICS
Connect the wall adapter and USB cable.
Plug the USB cable into the phone's charger/accessory port. With the phone screen facing you, make sure the USB symbol on the micro USB connector is facing upwards.
We recommend you unplug the charger from the wall socket after the phone is fully charged to save unnecessary power consumption of the charger.
Note: The Battery must be fully charged initially to improve battery lifetime.
Your phone has an internal antenna. Be careful not to scratch or damage this rear area, as that will cause loss of performance.
When the battery becomes fully discharged and you connect the phone to a charger, you will see a charging animation on the screen once the battery has charged sufficiently.
Warning: Use only LG-approved chargers, batteries and cables. When using unapproved chargers or cables, it may cause slow charging. Or, unapproved chargers or cables can cause the battery to explode or damage the device, which are not covered by the warranty.
Charging may be interrupted when you use a USB hub, which is not retained rated voltage.
