Why does the Xiaomi Pad 7 lag when making video calls using third-party applications?

Thank you for supporting Xiaomi products. The lag you're experiencing during video calls using third-party applications can occur due to the high load placed on the system when frequently launching and exiting APPs. This intense usage leads to a rapid rise in temperature, which triggers performance limitations as the system works to protect the device’s hardware, extend battery life, and maintain system stability. To ensure safe usage and optimize heat management, the device reduces performance in high-temperature conditions. To improve performance, we recommend allowing the device to rest until it returns to a normal temperature, and clearing any background applications to reduce load and enhance responsiveness.
