3. Reduce Unnecessary Data Consumption on iPhone

Apart from switching to Low Data Mode, you also can reduce excessive data consumption on your iPhone using the following techniques.

1. Only Allow Selected Apps to Use Cellular Data

Your iPhone can consume a lot of data if you allow all apps to access cellular data. It would be best to let only essential apps run on cellular data. To achieve this setting, go to Settings> Mobile Data and scroll through the apps listed to enable or disable those that access cellular data.

2. Turn Off Wi-Fi Assist

Your iOS device switches automatically to cellular data when your Wi-Fi connection misbehaves. This is made possible with the Wi-Fi Assist feature. To limit the use of this feature, you'll need to turn it off and save on cellular data consumption. While on your Mobile Data settings, navigate to Wi-Fi Assist and toggle it off.

3. Only Refresh Background Apps Using Wi-Fi

When background apps refresh, they consume a lot of data. To regulate cellular data consumption by background apps, you'll need only to allow them to refresh when on a Wi-Fi connection. To manage this setting, go to "Settings app" > "General" > "Background App Refresh".
