Pause other heavy activity, test three times near the router, then repeat where you actually use the phone. Record download, upload, and ping at similar times.
Create a clean baseline
A speed test shares the connection with everything else online. Pause cloud backups, downloads, and 4K streams when you want a baseline.
- Connect to the intended Wi-Fi network.
- Pause large network activity.
- Stand near the router.
- Run three tests and use the middle result.
Test the experience
Repeat the same test at your desk, couch, or bedroom. A strong baseline and weak room result suggests coverage; weak results everywhere suggest the router, modem, or service.
Common questions
Why do results change every time?
Network traffic, Wi-Fi conditions, test-server load, and device activity change from moment to moment.
Should I use cellular during the test?
No. Confirm the iPhone is connected to the Wi-Fi network you intend to measure.
