iPhone 14 Plus - Speedtests (speedtest.net web and app) and ping response very slow when compared to other devices

Since getting the iPhone 14 Plus, I've noticed significant discrepancies in speed tests and ping responses compared to my other devices. When I conduct a speed test using the Ookla app or website (with the same server and location), there's a notable difference between my iPhone and my MacBook Pro.

For instance, earlier today, I ran speed tests within 30 seconds of each other while connected to the same Wi-Fi network. The MacBook Pro showed a ping response of 48ms and a download speed of 68Mbps. In contrast, on my iPhone, the ping was 102ms, and the download speed was only 44Mbps. This pattern remains consistent across various Wi-Fi access points and ISPs.

Any insights or suggestions would be greatly appreciated.

Thank you!
