If Facebook is using too much mobile data in the background, it’s usually because videos autoplay, images load in high quality, and background syncing is enabled. In this updated 2026 guide, learn how to reduce Facebook data usage so you can browse longer without draining your mobile plan.

📘 Step-by-Step Guide

1. Open the Facebook app.
2. Tap the menu (☰).
3. Go to Settings & Privacy.
4. Tap Settings.
5. Scroll down and select Media.
6. Set Video Quality to Low or Data Saver mode.
7. Turn off Autoplay videos or set it to Wi-Fi only.
8. Disable Background App Refresh (iPhone) or Background Data (Android).
9. Reduce photo upload quality if enabled.
10. Restart the app and monitor your data usage.

💡 Pro Tip:
Using Facebook’s built-in Data Saver mode can significantly reduce mobile usage by compressing images and preventing videos from autoplaying unless you tap them.
