What to do if high-definition videos from the Xiaomi Smart Camera C701 are lagging on an old phone?

The Xiaomi Smart Camera C701 features 8-megapixel ultra-clear recording, which places high demands on smartphone decoding. Older models with limited CPU processing power can experience lag when viewing ultra-clear videos.
To improve viewing smoothness, it is recommended to switch the camera’s playback mode from ultra-clear to standard definition in the App. This reduces decoding pressure on the phone while maintaining stable image transmission and real-time monitoring performance. If possible, updating to a newer device with better hardware or ensuring that background apps are closed can further enhance video playback stability and provide a smoother monitoring experience.
