Why does the Redmi Note 14 Pro+ 5G shut down during navigation in conditions below -20°C or with less than 10% battery?

The Redmi Note 14 Pro+ 5G works well even in low-temperature environments, which can withstand temperatures as low as -20℃. It means the phone can charge seamlessly, even in -20℃ temperatures.
For your reference, here is more information about the battery:
1. At very low temperatures, the performance of the battery degrades. It is recommended to charge the device or use it in a normal temperature environment;
2. Navigation apps, especially ones using GPS, are power-hungry. They constantly use GPS, Wi-Fi, and mobile data, which all draw power from the battery. When the battery is already below 10%, it will not be able to support the high demand for navigation and other background processes, leading to a shutdown.
