Before you begin the iOS Speed Test, below are some tips to get accurate results
Close All Apps
Close every app such as Netflix, Hulu, Spotify, Facbook, Twitter, Instagram etc. Close all browsers windows and tabs (except the one you're using for the test)
If any app is open which uses Internet, you should close it down before you run the test.
Disable Wifi / Hotspots
If you have created any hotspot from your device you need to disable it till test completes
Disable any wifi connection which might be enable on your iOS device
Restart / Reboot / Airplane mode
Restart or Reboot the iOS device once to get best results. If not possible thenat least turn on Airplane mode once & then turn it off after one minute. This way you can get a fresh connection to nearest Cell tower.
