iPhone 15 plus internet speed is 50% than iPhone 13 at the same wify network.

Speedtest is not all that accurate at times displaying "results", but looking at your screenshot, both phones are within 1 Mbps of each other.

45.41 vs 46.22

Not much difference there.

If you are looking at the 26.7 number......there is an example of incorrect info displayed.

Network Sped:

Any difference as of your reply? Looks like something was downloading, according to your photos. Nonetheless, don’t expect it to always be the same —system services are running in the background.

Thank you for the screenshot.

Why Network Speed may be Down:

Intense Downloads:

You are downloading something, and that can eat system resources, while in the process. It may be a file, to cookies and caches.

Download Speed is Up:

In image one: 102

In Image two: 147

When Internet Data Transfer Rate is Down:

1. Downloading something
2. Not having strong enough of a router to get optimal speeds
3. Not using Ethernet
4. Aging device
5. Using encryption
6. Usage Restrictions
