What you need
Steps
Open Settings, tap General, then iPhone Storage. Wait for the list to load and note how much space System Data and iOS are using.
In Settings, go to Apps, then Safari, then Advanced, then Website Data. Tap Remove All Website Data to wipe the stored site cache.
Open Safari, tap the tabs button, then tap Clear. Choose a time range such as all history and confirm with Clear History.
Go to Settings, Apps, Messages, then Keep Messages. Change Forever to 1 year or 30 days so older texts drop off automatically.
Open Messages, pick a conversation, long press a message, tap More, select what you don't need and tap Delete. Clear large photo and video attachments too.
In Settings, open Privacy & Security, then Analytics & Improvements. Turn off Share iPhone Analytics and Share iCloud Analytics.
On the same screen, tap Analytics Data. Swipe left on each log and tap Delete to remove the stored reports.
Run a maintenance shortcut or script from a source you trust. Check what it does before you run it, then restart the phone.
Open each social app's settings and look for a clear cache or free up space option. If there isn't one, delete and reinstall the app.
Restart your iPhone and check iPhone Storage again. System Data should drop, though a small amount always comes back.
Tips and common mistakes
Back up to iCloud or a computer before deleting messages or website data, since those deletions cannot be undone.
System Data refills with caches and logs, so repeat this cleanup every few months.
Don't run maintenance scripts or shortcuts from random links, because they can reach your personal data.
Deleting and reinstalling a single app is the most reliable way to clear one stubborn cache.
Questions
Where do I find System Data on my iPhone?
Open Settings, tap General, then iPhone Storage. Scroll below the app list and the storage bar shows System Data as its own category.
Will clearing System Data delete my photos or apps?
No. These steps remove caches, analytics logs and old messages. Your photos and apps stay in place, but back up first anyway.
Does clearing Safari history free much space?
Usually only a little unless the cache is large. Old message attachments and social app caches normally give you bigger savings.
