Connect The Headset - Microsoft Lumia 640 XL LTE User Manual

You don't need to charge the battery for a specific length of time, and you can use the phone
while it's charging.
If the battery is completely discharged, it may take up to 20 minutes before the charging
indicator is displayed.
Tip: 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.
Make sure your computer is switched on.
First connect the USB cable to the computer, then to your phone. When the battery is
full, first disconnect the USB cable from your phone, then from the computer.
The battery can be charged and discharged hundreds of times, but it will eventually wear out.
When the talk and standby times are noticeably shorter than normal, replace the battery.
