Wifi on iPhone cuts out

Hi all


Lately I have found that when my iPhone 12 turns off (not completely off!) it loses the Wifi and reverts to 4G. When I turn the phone back on it eventually picks up the wifi again. Obviously I’m worried how much data is being used when it’s gone onto 4G. I have cut out all but the necessary apps which run in the background but I really need this sorting asap. Any thoughts?


Many thanks for any help.


p.s. I am running iOS 14.8 on my iPhone 12

Start Here: If your iPhone, iPad, or iPod touch won’t Connect to a Wi-Fi Network - Apple Support


Other Thoughts:

A. Clear Temporary Internet Files:

If Safari is slow, try clearing out your Temporary Internet FilesHistoryCache, and CookiesGo Here: Clear your Safari browser history and set up content blockers on your iPhone, iPad, or iPod touch


B. Disable Cellular:

Try disabling Cellular, and using Wi-Fi instead, seeing if that makes all the difference.
