iPhone keeps dropping Wi-Fi connection and switching to cellular

Starting 4/11/2025, my iPhone started to develop connection issues with my home’s wifi, it would be running smoothly, then within seconds, it would suddenly become sluggish and slow. Causing my phone to revert to the cellular service. After a minute or so, it would revert back to wifi to start the cycle over again.

This connection issue DOES NOT affect any other device in our house, and it happens with other routers as well.

I have tried: Updating, resetting my network settings, reconnecting to wifi networks, and so much more.

WHAT DO I DO?!?!

You are way overdue for a battery replacement, Apple recommends replacing the battery when it reaches 80% of it's health.

Batteries degrade over time with usage due to chemical aging, that's just how they work.

You can expect about a 1% drop per 50 charging cycles with average use on an iPhone. This is an approximation, that is why it may be plus or minus a few percent on a month to month basis.

Apple recommends replacing it when the battery health reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.

Since the latest iOS update my iPhone is constantly (a few times per minute) dropping WiFi connectivity. I have gone through the steps of removing my WiFi from the device and then readding it, removing my work VPN and then rebooting the phone, and also just rebooting in general. How do I get WiFi to reliably work again on my device?
