Why does the camera lag when rapidly zooming in and out in the Redmi Note 13?

Rapid zooming requires significant processing power. If the phone's processor or GPU cannot handle the rapid changes, it can cause stuttering. The physical camera hardware will struggle to quickly adjust focus and exposure when zooming rapidly. If the Redmi Note 13 gets too hot, it will throttle the CPU and GPU performance, leading to stuttering. Besides, insufficient RAM can cause performance issues. Other third-party APPs running in the background will use up available memory. The platform does not support smooth transitions between the ultra-wide and wide cameras. This is considered a normal phenomenon and you can use it with confidence.
