How To Reduce Your Data Usage On iPhone

iOS can help you you stay under your data plan limit so that you can save on your mobile bill. Even though many carriers are now offering unlimited data plans, we, however, often see unexpected charges or other hidden charges and limits. There are many ways to reduce cellular data usage. This article explains how you can reduce your data usage on your iPhone.

This article explains how you can limit and manage your cellular (mobile) data usage on your iPhone. You may find this article very helpful especially if you have an unlimited data plan. I, myself, find that I go over my monthly data allowance data. Then, I have only one option to avoid incurring additional charges:  I need to either throttle back your data usage. If this is the case for you also, it is time to make changes. Luckily, iOS offers great features to do this.

This article is mostly optimized for the latest version of the iOS software. For earlier iOS versions, please see this article.

The focus of this article is on limiting and controlling cellular data use, if your phone cannot connect to a cellular network, see this article.

Keep Your Data Use in Check

The first step is to know how much data you’re using. Check your data usage on your iPhone. On your device go to Settings > Cellular or Settings > Mobile Data. Scroll down and you will see your apps, in order of data usage. If you do not want a certain app to use cellular data, you can turn mobile data off this app. In fact, I disabled Netflix. So The Netflix app does not use data. You may want to do this as well for similar apps, especially if Wi-Fi Assist is enabled. Because your phone may switch to use cellular data while you were watching a Netflix movie. And this may use a lot of data.

  2. See current data usage. Some apps may use cellular data to connect to the Internet. You can limit this. If your phone is not connected to a Wi-Fi connection, your phone will use cellular data. You can also turn off or on cellular data for certain apps. Go to Settings > Cellular and find the “Cellular Data” section. You can which apps are using cellular data. Try to figure out why some apps using the most data. You can prevent any apps from using cellular data. If you want to do so, simply toggle off for that app. When you turn this off, disabled apps will only use Wi-Fi to access to the Internet. There are several apps that you can control, such as:
    • Photos. Photo updates, like iCloud photo updates, may use cellular data. You can also change its cellular data settings by going to Settings > Photos to limit this. There are two options here (a) Cellular Data, toggle this off if you want to disable cellular data and (b) Unlimited Updates. If you enable the Cellular Data option, you may want to turn this off as this means your phone will employ unlimited cellular data use.
    • TV. The TV app will let you watch content from many video provider services. For Playback, this app may use cellular data. You also can limit this by going to Settings > TV > and toggle “Use Cellular Data for Playback” off.

  4. Wi-Fi Assist. You may want to turn this off. If this is enabled, your iPhone will automatically use cellular data when you have a poor Wi-Fi connection. This may lead to some unwanted results.

  5. iCloud Drive. iCloud Drive is Apple’s version of cloud-based document management. This, iCloud Drive, will let you keep all your content and documents up to date across all your iOS and macOS devices. iCloud Drive will use cellular data when there is no Wi-Fi connection. You can limit this. Go to Settings > Cellular and scroll down and toggle off “iCloud Drive”. (see also: iCloud is full?)
  6. Automatic Downloads. If you enable automatic downloads (Settings > iTunes & App Store), your purchases (apps, musics, books, etc) on your iPhone or other iOS devices will download to all of your other devices. And this may use cellular data that you want to limit. Go to Settings > iTunes & App Stores and toggle off “Use Cellular Data”.Automatic Downloads
  7. Reading List. If you are using the Safari reading list, this may use cellular data to download for offline reading. You may want to disable this. Simply go to Settings > Safari > and turn off “Automatically Save Offline”. Another note, you may want to turn off auto-play videos in Safari.
  8. Mail. Ok. We do not recommend disabling mail to save cellular data (although you may want this, if you do, go to Settings > Mail and turn off “Cellular Data”). However, you may disable Fetch New Data or you may want to fetch mail less frequently. You can change these settings by going to Settings > Passwords & Accounts > Fetch New Data.

Other tips to cut back on iPhone data usage

  • Use Wi-Fi whenever possible.
  • Use Low Data Mode when needed. iOS has a new feature called Low Data Mode. When you turn this on, some iOS features and background network use are paused. For example, iCloud photo updates will be paused. This will help you reduce not only cellular data usage but also Wi-Fi. However, it may not be best to keep this off forever. You can access this setting on your phone by going to Settings > Cellular > Cellular Data Options. Low Data Mode
  • Some apps may have their own settings to save cellular usage. Contact their developers to learn more.

  1. Would be nice to have an app that would take care of this automatically. I am on spectrum at home and my phone still uses data sometimes instead of wi-fi. Don’t know what to do except to turn data off and leave it off until I need it.


    • In case you are not aware off, Android OS has option to set cellular data limit besides enable/disable data.But then you need to get an Android phone. Some even have dual SIM and dedicated micro sd card slots, so I can have 2 whatspp accounts and 2 facebook accounts and I can have more storage via the sd card as well. And finally at a much lower price compared to an iPhone of similar features for some models. Good luck and keep safe in these trying times.

  2. This is great! Thank you. Hopefully this helps my data usage to go down and not go over the limit. It can be quite costly. Thanks for your help!

  3. Crossing my fingers this helps. We Currently don’t have WiFi access at home. My son is burning thru his data mainly using that Tik Tok app. So hopefully all these suggestions will save some data usage.

  4. This is terrific. My phone is eating data like crazy and it costs us so much money. I had everything turned on. My AT&T usage showed it is my phone that is the culprit. I’m looking forward to seeing how much less I use now. Thank you.
