October 3, 2015 — by Hawon Nguyen0

Many users who recently upgraded to iOS 9 reported high consumption of cellular data on their iPhone or iPad, despite the same usage as to before they decided to download the software update.

While most iPhone and iPad users have an unlimited data to waste, some are literally saving up their mobile data to avoid charges from the carrier. In this article, we will show you a few simple methods to reduce high cellular data usage after updating to iOS 9 for both iPhone and iPad.

Disable Wi-Fi Assist in iOS 9

When Apple release iOs 9 to the public, there are certain features that they didn’t inform users about, and Wi-Fi Assist happen to be one of them. This feature is turned On by default and it helps to improve your browsing experience by switching to your cellular data once the device detects a low signal in your current Wi-Fi network.

Even though this is definitely useful for some users as they can continue to use the internet without interruption, Wi-Fi Assist does increase the data usage. If you noticed that there is something going on with the data statistics, this is the feature you want to turn Off.


  1. Open up the stock Settings app
  2. Go to Cellular and scroll down the bottom of the page
  3. You will see an option called Wi-Fi Assist, simply disable it.

Disable Background App Refresh

Whenever your iPhone or iPad is connected to a Wi-Fi network or using your mobile data, the applications on your home screen will then refresh itself in the background, without it being launched. Not only that it contribute to killing your cellular data, Background App Refresh is also well-known for wasting our battery life.

  1. Go to the Settings app
  2. General > Background App Refresh
  3. This feature is also turned On automatically, toggle the option to Off.

Turn Off Automatic Downloads from App Store

This isn’t a brand new feature in iOS 9, but it’s not old either. Automatic Downloads can be found in your iTunes & App Store section. This functionality allows the App Store to update your current applications to the latest version, everything is done in the background so you won’t even have to worry about entering the iTunes password or anything. However, it also use whatever Wi-Fi network you’re on or even cellular data.


  1. From the Settings app, navigate to iTunes & App Store
  2. Scroll down to the Automatic Downloads section
  3. Toggle Updates to Off

The best thing to do is disable Automatic Downloads and you can update whichever apps you want by going to the App Store.


Hopefully, these 3 methods will help you reduce high cellular data usage on your iPhone or iPad, after upgrading to iOS 9. You can also do the same thing to previous firmware such as iOS 7 & 8.
