For news junkies, crypto traders, and culture enthusiasts, X (formerly Twitter) is an indispensable real-time information firehose. But as you scroll through your 'For You' timeline, the app quietly executes massive background downloads of video clips, animated reaction GIFs, Spaces audio buffers, and article previews. If you are struggling with low disk capacity, clearing X (Twitter) cache on iPhone is one of the most effective steps you can take to instantly recover 2 to 6 GB of storage.
Executive Summary & Research Finding
Clear X (Twitter) cache on iPhone & Android to free up 3+ GB of media storage. Learn how to wipe web cache, media storage, and Spaces audio safely.
Fortunately, X is one of the few mainstream social apps that provides dedicated, built-in storage management tools on iOS and Android. Rather than forcing you to uninstall the application or guess which files to delete, X separates its temporary data into two distinct categories: Media Storage (video chunks, photos, and animated GIFs) and Web Storage (in-app browser cookies, saved passwords, and cached web pages). Wiping these caches will never delete your posts, bookmarks, lists, or direct messages.

The Anatomy of X App Storage: Media vs Web Storage
Before hitting clear, examine how X categorizes its temporary footprint across your device's flash memory:
| Data Category | Source Content | Typical Footprint (3 Months) | Impact of Clearing | Will It Delete Your Posts? |
|---|---|---|---|---|
| Media Storage | Timeline video pre-buffers, photo attachments, GIFs, avatars | 1.5 GB – 4.5 GB (Largest) | Reclaims immediate disk space; media re-streams on demand | No (100% Safe) |
| Web Storage (Page Cache) | HTML, CSS stylesheets, and images from external links clicked in X | 250 MB – 900 MB | Dumps cached web pages without affecting logins | No (100% Safe) |
| All Web Storage | Page cache plus all in-app browser session cookies and site logins | 100 MB – 300 MB | Logs you out of external sites opened inside X's internal browser | No |
| Spaces Audio Cache | Temporary audio streaming buffers from live voice conversations | 300 MB – 1.0 GB | Purged automatically with media storage cleanup | No |
Step-by-Step: How to Clear X (Twitter) Cache on iPhone
Follow these exact steps inside the official X app on iOS to liberate gigabytes of storage in under 30 seconds:
- Open the X app on your iPhone.
- Tap your Profile avatar in the top-left corner to open the side navigation drawer.
- Tap Settings and Support, then select Settings and privacy.
- Scroll down to the General section and tap Accessibility, display, and languages.
- Tap Data usage at the bottom of the menu.
- Scroll to the bottom where you will see the Storage section: tap on Media storage.
- Tap Clear media storage (or tap it twice to confirm). This purges cached photos, GIFs, and video buffers.
- Go back one screen, tap Web storage, and select Clear web page storage to dump temporary browser data.
How to Clear X Cache on Android
Android users can perform the in-app cleanup outlined above, or execute a fast system-level cache purge:
- Open your phone's Settings > go to Apps.
- Select X from the application list.
- Tap Storage & Cache.
- Tap Clear Cache. This instantly eliminates several gigabytes of video pre-buffers without touching your account credentials.
- Warning: Do not tap Clear Storage unless you wish to log out and reset the app completely.
Video Autoplay Warning
X's default setting is to autoplay every video in your feed, pre-buffering high-definition video chunks even if you scroll past them in a split second. Go to X Settings > Accessibility, display, and languages > Data usage > Video autoplay, and set it to 'Never' or 'Wi-Fi only' to drastically reduce ongoing storage consumption.
How to Keep the X App Lightweight Permanently
- Enable Data Saver: In X's Data usage settings, switch on Data saver. This automatically throttles background video pre-fetching and loads images in standard definition.
- Disable High-Quality Video: Set High-quality video playback to Wi-Fi only to prevent massive 1080p and 4K video streams from chewing through mobile data and flash cache.
- Monthly Cleanup Habit: Because X does not automatically self-expire its media cache, establish a monthly routine of tapping 'Clear media storage'.
Maintain a High-Performance Smartphone
Clearing the X app's media cache provides instant storage relief and resolves timeline stuttering. But if your smartphone's storage gauge remains near capacity, you should also look into clearing hidden iPhone system data and cached logs.
To keep your device running at maximum speed without constant manual maintenance, install Clearly Smart Storage Cleaner. Its smart diagnostic tools spot redundant media files, identify heavy duplicate photos, and allow you to free up storage and clean phone memory in seconds.
