Mobile data can disappear fast—especially if you stream videos, scroll social media, or use apps that quietly run in the background. While most people rely on basic options like turning off mobile data or using Wi-Fi, modern smartphones also include hidden or lesser-known settings that can drastically reduce data usage without affecting everyday performance.
Below are some of the best hidden settings and tricks to help you save mobile data on both Android and iPhone.

What it does:
- Stops apps from using data in the background
- Reduces data usage for system services
