iPhone 15 replacement keeps restarting and loses Wi-Fi I have a new Iphone 15, this new phone is the replacement I was given at the Apple store in Troy,MI to replace a new Iphone 15 I purchase that kept rebooting(restarting), The first Iphone had issues right out of the box. Now the replacement phone is doing the same thing. I had to restore from a iCloud back up and this worked for about a week, but now it is once again restarting and once restarted has no Wifi [Re-Titled by Moderator] Original Title: Iphone 15 keeps restarting

Why is my iPhone behaving abnormally with WiFi turned on? Suddenly my iPhone stopped many functions dependent on data (Safari, newspaper and other apps, etc.) It makes phone calls OK. When I turn WiFi off, it appears to function normally. I first thought my router was bad, but all the other Apple devices here are working fine with WiFi. I’ve tried turning WiFi off and on repeatedly and shut down the phone and restarted, but the problem remains. Any advice?

Hello~ Check your battery health as *LD150* suggests…Settings > Battery > Battery Health. What’s your %? In the meantime…

Similar things can happen when VPN or security apps are installed in phone or router.

Is it only your router or any?

What is your battery "health"?
