On my iPhone the YouTube app is slow for loading the video so the video stops playing and I have fast Internet like 15 Mbps how do I fix it
Why is YouTube slow on my iPhone?
YouTube is slow in general on iPhones. Try getting rid of some space? Charge your iPhone? Be patient? If the videos are more then 5 minutes it usually gets frustrating to wait, but YouTube is always slow on iPhones, trust me.
It is not mobile errors only network errors.
Are you using a mobile internet connection? That's usually slow loading, unless your network gives you 4G LTE service (the fastest type of mobile internet).
Have you tried using a Wi-Fi connection instead?
Also, the problem might not just be the bandwidth - it could also be a large video file sucking up too much memory on your phone and slowing it down.
