iPhone 16 Pro cycling WiFi and Bluetooth constantly

Hi,

I recently upgraded my iPhone 12 Pro to and iPhone 16 Pro and I must admit that the experience has been pretty terrible thus far. The WiFi and cellular data performance seem worse than my old iPhone 12 Pro. It is haphazardly sluggish to load web pages when other devices in the house work flawlessly. I even upgraded to iOS 18.0.1 hoping it would fix things but that hasn’t done it.

One very strange behavior is that the device cycles through automatically turning off Bluetooth and resetting the WiFi connection while in our house, even though I’m not turning off the Bluetooth or the WiFi myself. It seems to be a constant cycle of nearly every 30-60 seconds. And I suspect it is wearing the battery down as it does this since I have lost 20% charge so far in sparing usage during past 3 hours.

Certainly not the user experience I think most people were looking for from a new iPhone. Seems like others are having similar problems on Reddit.

Any help or suggestions would be welcome. Thanks!
