As per your concern, we want to inform you that while 5G devices work with both LTE and 5G networks, they may consume more battery and generate more heat compared to LTE devices. High-speed processing for heavy data can lead to increased energy usage and device heating. If your device gets too hot, our safety algorithm may limit performance and switch to 4G temporarily to prevent overheating. This is normal and helps maintain device performance.
In this case, please wait for the device to get cool down for a while and then use the device again. If the 5G device gets cooled down to a specific temperature, the device will connect to the 5G network again.
However, please perform the below-mentioned troubleshooting steps, these may help in resolving your concerns.
