In this article, I’ve listed those tricks that worked for me. Scroll down to take a look at all of them!

Enable Low Data Mode on your iPhone

When the Low Data feature is enabled on your iPhone, it pauses the background apps and automatic updates. This in turn limits your cellular data consumption as well as your Wi-Fi usage.
So your first step to stop unnecessary data consumption on your iPhone is to enable the Low Data Mode. Here’s how to do it:

Ensure ‘Automatic Downloads and Updates’ is disabled

Another heavy data consumer is the ‘Automatic Downloads and Updates’ setting. While this can prove to be incredibly useful for updating and downloading apps from the app store, it is better to be disabled if you want to save your data. Besides, you can always download and install apps manually from the app store.

Disable Auto-Play Videos feature

The auto-play feature of App Store and Safari is incredibly useful to take a sneak peek into the apps and videos. You have a clear idea of which apps match your taste and which are not of your interest.
However, this feature takes a heavy toll on your battery as well as mobile data. Similarly, the auto-play feature slows down the web browser. So it is better to turn off this feature. Let’s see how:

Disable Auto-Playing videos on App Store: Head to Settings > App Store > Video Autoplay. Now you can either turn off this feature completely or enable it for Wi-Fi only.

Disable Auto-Playing Videos in Safari: Head to Safari Settings> Accessibility > Motion. Turn off the switch next to Auto-Play video previews.

Disable Background App Refresh

Apple’s Background App refresh functionality is infamous for battery drain as well as high data consumption. If you don’t turn off this setting right now it will gulp your limited cellular data in just a few days. Apple allows you to enable background refresh for individual apps or when you’re connected to Wi-Fi.
