Charge your device
Your battery has been partially charged at the factory, but you may need to recharge it before you can use your device.
Charge the battery
- Plug the charger into a wall outlet.
- Connect the charger to the device.
Do not overcharge the battery: once charging of your device is complete, first unplug the charger from the device and then from the electrical outlet.
Do not overuse the battery: avoid letting the battery charge drop below 20% or using it until it runs out of power and shuts down.
If the battery is completely discharged, it may take several minutes before the charging indicator is displayed.
Tip: You can use USB charging when a wall outlet is not available. 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.
Your device has an internal, non-removable, rechargeable lithium-polymer battery. Do not attempt to remove the battery or back cover, as you may damage the device. To replace the battery, take the device to the nearest authorized service facility.
