Use proper care when using optional protective or battery cases.

Cases can be useful to help protect your device from damage or to provide additional battery storage.

•When a device is enclosed within one of these protective charging cases, it might be difficult for the device and battery to properly dissipate the heat that is being generated.

•If the device begins to get hot or seems to have difficulty cooling down, please remove the device from its external case and allow it to cool down before placing the case back on.
