1. Efficient Data Saving Methods for iPhone Running iOS 13
Are you utilizing a limited mobile data plan (3G/4G) and seeking to conserve data for prolonged usage? The Low Data Mode feature on iPhone can assist you in this endeavor.
Low Data Mode disables all background communications. It turns off the Background App Refresh feature of apps, requiring them to postpone all sync tasks until you connect to an unlimited data network.

Moreover, it also halts all background sync tasks. Therefore, when you enable this mode, the Photos app will not back up your images. You won't notice a difference when using your iPhone for basic daily tasks, but all background processes you typically don't control will be paused. If necessary, you can manually enable sync tasks for each app.
How to Enable Low Data Mode for 3G/4G Network on iPhone Running iOS 13
To enable Low Data Mode for Cellular Data connection, open the Settings app on your iPhone, and select the Cellular option.

Proceed to select Cellular Data Options from this point.

Flip the switch next to Low Data Mode to activate this feature.

How to Enable Low Data Mode for Wi-Fi on iPhone Running iOS 13
Low Data Mode also functions on Wi-Fi networks. However, not all Wi-Fi networks support this feature. If a Wi-Fi network does support it, you can enable it as follows:
Open the Settings app, and select Wi-Fi.

Here, locate the Wi-Fi network you wish to enable Low Data Mode for, and tap the small 'i' button next to it.

From the screen that appears, toggle the switch next to Low Data Mode to activate it.

Furthermore, you can enable Low Data Mode for specific apps or services. For instance, Instagram offers the Low Data Mode option. To save data on streaming apps, simply reduce video or audio quality.
You can also disable Background App Refresh and auto-download for apps to reduce the amount of data your iPhone consumes.
