In this guide, I have explained various easy troubleshooting methods to fix the YouTube video lagging issue on iPhone. When you are all set to enjoy your favorite videos on YouTube, the app stops working.

The video player takes forever to load. Even if it manages to load, the video lags every few seconds.

Here are a few possible reasons why YouTube videos lagging on iPhone. The internet network may be unstable. Usually, when you use mobile data instead of WiFi, the video doesn’t buffer smoothly due to slow bandwidth.

The version of YouTube you are using may require an update to a newer version. An older version may develop technical glitches and similar issues.

Best Ways to Fix YouTube Video Lagging on iPhone

1. Disable VPN App on iPhone

VPN apps are infamous for suddenly slowing down the network due to load on the remote server. Unless necessary, turn off the VPN app on your iPhone.

  1. Head to Settings > VPN > tap the switch beside VPN to turn it off.

2. Use WiFi Network to Run YouTube

Instead of relying on slow mobile data, I suggest switching to a WiFi network and connecting your iPhone to that.

Watching HD-resolution videos using mobile data will only cause the stutter issue to become more persistent. A WiFi network guarantees smooth video playback except when the ISP servers are down for maintenance.

3. Force Close YouTube App 

Here are the steps to force close the YouTube app on iOS.
