As an experienced mobile technology expert, I can provide you with comprehensive guidance on limiting data usage on your Android device.

1. Monitor Data Usage:
The first step is to monitor your data usage to identify patterns and areas of excessive consumption. Go to Settings > Network & internet > Data usage to view your data usage over time.

2. Set Data Limits:
Once you have a clear understanding of your data consumption, you can set data limits to prevent exceeding your plan. In the same Data usage section, tap Data warning & limit. Enable Set data limit and choose a threshold that aligns with your plan.

3. Use Data-Saving Features:
Android offers several built-in data-saving features. Go to Settings > Network & internet > Data saver and enable it. This feature minimizes data usage by optimizing background app activity, image loading, and video streaming.

4. Restrict Background Data:
Some apps may continue to use data even when you're not actively using them. To restrict background data usage, go to Settings > Apps & notifications > App info. Select the app, tap Mobile data & Wi-Fi, and disable Background data.

5. Limit App Data Usage:
Certain apps may significantly contribute to your data consumption. In the same App info section, tap Data usage. Here, you can view the app's data usage and set limits to control its data consumption.

6. Disable Automatic Updates:
Automatic app and system updates can consume large amounts of data. Go to Settings > System > Advanced > System update. Disable Auto-update system. For apps, go to Google Play Store > Menu > Settings > Auto-update apps. Choose Auto-update apps over Wi-Fi only or Don't auto-update apps.

7. Use Wi-Fi Whenever Possible:
Wi-Fi networks provide unlimited data usage, so prioritize using Wi-Fi over cellular data whenever possible. Connect to available Wi-Fi hotspots in public areas or configure your home Wi-Fi network.

8. Compress Data:
Some browsers like Opera Mini offer a data compression feature. This feature reduces the size of web pages and images, resulting in lower data usage.

9. Monitor App Permissions:
Certain apps may request access to your location, camera, or other features that may consume data. Regularly review app permissions in Settings > Apps & notifications > App permissions and revoke permissions for unnecessary data-consuming features.

10. Use Data-Tracking Apps:
Third-party apps like Data Monitor or My Data Manager can help you track your data usage in real-time and identify apps that are consuming excessive data.
