using a standard battery charger.

If the device heats up or the ambient air temperature rises, the charging speed may
decrease automatically. This is a normal operating condition to prevent damage to
the device.

The device has a built-in wireless charging coil. You can charge the battery using a wireless
charger (sold separately).
Fast wireless charging
You can charge your device faster using the fast wireless charging feature. To use this feature,
you must use a charger and components that support the fast wireless charging feature.

reduce the fan noise, you must deactivate the fast wireless charging feature.
