Why is my iPhone using so much data despite the fact that I am tethering it from another device?

I have two iPhones: iPhone A is a work iPhone with unlimited data plan. iPhone B is my personal iPhone with limited data plan. iPhone B has background app refresh limited to wifi only.


I frequently tether iPhone B(personal) to iPhone A(work) to use the unlimited data from iPhone A, but during this time, data usage on iPhone B is constantly going up, why?

Hello yair_marx,


That's a fantastic question. To confirm, are you performing more data enabled tasks on your personal iPhone when connected to the Personal Hotspot of from your work iPhone? If so, let's take a look at the Wi-Fi Assist setting. If this setting is enabled, your iPhone would automatically switch to using cellular data if your iPhone experiences a poor Wi-Fi connection. You can learn more about this setting via the following article, and turn this setting off using the steps listed below.


  1. Tap Settings.
  2. Tap Cellular or Mobile Data.
  3. Then tap the green toggle next to Wi-Fi Assist to disable.
