Part 3. FAQs about FaceTime lagging

Q1: Is there a minimum internet speed required for FaceTime to work smoothly?

Apple doesn't specify a minimum speed, but a good rule of thumb is to have at least 1 Mbps for a reliable FaceTime call. Higher speeds will generally improve the quality and reduce lag.

Q2: Can the distance between callers affect FaceTime lag?

The physical distance between callers can affect latency, as data has to travel longer distances. However, this is usually not noticeable unless there is an issue with the network routing.

Q3: Will FaceTime lag less if I reduce the video quality?

FaceTime automatically adjusts video quality based on the connection speed. Manually reducing video quality is not an option, but a stronger connection will naturally improve video quality with less lag.
