When the ambient temperature exceeds the recommended range, the (Battery status) icon will appear on the status bar and charging will be forcibly terminated. This is done as a precaution and it's not a malfunction.
The recommended operating temperature range is 5 °C to 35 °C (41 ºF to 95 ºF). We recommend that you use the device in an environment within the recommended temperature range.
