Many iPhone users are unaware of the numerous configuration options available on their devices, which can sometimes lead to unexpected data usage costs. While unlimited data plans have become common, there are still users who prefer more affordable options, especially when they are often within reach of a Wi-Fi connection. However, during busy periods like Christmas or when traveling, it’s essential to manage data consumption effectively. Here, we introduce two settings that will help you maintain control.

Wi-Fi Assistance
A lesser-known feature on your iPhone is Wi-Fi assistance, which has been available for some time. As mobile operators expanded their data offerings, Apple introduced this feature to allow users to seamlessly switch between Wi-Fi and mobile data when the Wi-Fi signal is weak or unstable. This automatic selection ensures a smooth online experience without the need to constantly toggle between networks. To enable it, follow these steps:
- Open your iPhone’s Settings.
- Scroll down and tap on Mobile Data.
- Continue to the bottom and locate the Wi-Fi Assist option. With Wi-Fi assistance enabled, your iPhone will prioritize Wi-Fi connections when available, preventing unintended data usage when the Wi-Fi signal weakens.
Data Reduction Mode
An even lesser-known option is the Data Reduction Mode, which can significantly reduce data consumption by pausing automatic updates and background tasks for apps. This mode focuses solely on foreground applications, optimizing your device’s efficiency and speeding up transitions. To activate Data Reduction Mode, follow these simple steps:
- Access your iPhone’s Settings.
- Tap on Mobile Data.
- Select Options.
- Under Data Mode, choose Low Data Mode. By combining these two settings, you can effectively manage and reduce your monthly data usage without compromising your mobile experience.
With these hidden iPhone features, you can take charge of your data consumption and enjoy more control over your mobile expenses.
