Why is the recording time of the Xiaomi 15 Ultra short?

Thank you for your support for the Xiaomi product. We apologize for the inconvenience.
The recording time of the camera will be affected by many factors such as hardware specifications, parameters, heat dissipation, algorithms, frame rate, frame drop, power consumption, etc. Recordings with different specifications will have completely different recording times. The Xiaomi 15 Ultra has industry-leading camera specifications, as well as excellent heat dissipation and power consumption control capabilities, and its imaging quality is in a leading position in the industry. If you want to get longer recording time, it is recommended that you appropriately reduce the resolution or frame rate to meet the shooting needs of the corresponding scene.
