iPhone Internet Speed Test

Check the internet speed of your iPhone or iPad. The test measures download speed, upload speed and ping (latency). Press the start button below and your results appear when it finishes.

How to get an accurate speed test on iPhone

  1. Close apps that stream, sync or download in the background, and pause iCloud Photos uploads if they are running.
  2. On Wi-Fi, stand in the room where you normally use your phone. On cellular, test where you normally use it.
  3. Turn off any VPN while testing, since it can lower measured speed. Switch off Wi-Fi (to test cellular) or cellular (to test Wi-Fi), so you know which one you are measuring.
  4. Run the test two or three times and compare. Speeds vary by time of day.

What is a good internet speed?

Use this as a rough guide for what common activities need. The numbers are for one person or device at a time, so add them up for a busy household.

ActivityRoughly needsMatters most
Browsing, email, messaging1–5 MbpsDownload
HD video streamingAbout 5 Mbps per streamDownload
4K video streamingAbout 15–25 Mbps per streamDownload
FaceTime and video calls2–5 Mbps each wayUpload and ping
Online gaming3–10 MbpsPing (lower is better)
Backing up photos and videosFaster upload means faster backupsUpload

Streaming services publish their own recommendations, which change over time. Treat these figures as a starting point.

What the numbers mean

  • Download speed is how fast data reaches your iPhone: streaming, browsing and app downloads.
  • Upload speed is how fast your iPhone sends data: video calls and photo backup.
  • Ping (latency) is the round-trip delay in milliseconds. Under about 50 ms feels responsive. Over 100 ms you notice lag in games and calls.

Mbps is not MB/s

Speeds are measured in megabits per second (Mbps). File sizes use megabytes (MB). There are 8 bits in a byte, so divide Mbps by 8 to estimate MB per second. A 200 Mbps connection downloads at about 25 MB per second.

Why is my iPhone slower than the plan I pay for?

  • Wi-Fi distance and walls. Speed drops quickly the farther you are from the router. 5 GHz Wi-Fi is faster than 2.4 GHz but covers less distance.
  • Many devices at once. TVs, laptops and cameras share the same connection.
  • An older router. It may not support the Wi-Fi standard your iPhone can use.
  • Low Data Mode. Check Settings > Wi-Fi > (i) and Settings > Cellular > Cellular Data Options for Low Data Mode, which can limit background activity.
  • VPN or Private Relay. Routing through another server adds delay. See how these work.
  • Cellular signal and congestion. Speeds on 5G and LTE vary a lot with signal strength, location and how busy the tower is.
  • Plan speeds are "up to". What you pay for is the maximum, not a guarantee.

Slow connection? Quick fixes

  1. Toggle Airplane Mode on for ten seconds, then off.
  2. Restart your router and your iPhone.
  3. Move closer to the router, or switch between 2.4 GHz and 5 GHz Wi-Fi if your router offers both.
  4. If Wi-Fi connects but nothing loads, see how to fix an iPhone Wi-Fi connection with no IP address.
  5. If problems persist, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This forgets saved Wi-Fi passwords.
