# How to Clear Photos Cache on iPhone

iOS does not give you a simple "Clear Cache" button for the Photos app. But there are real ways to reduce Photos-related storage and rebuild the cache. Here is how.

## Quick Answer

iOS has no explicit **Clear Cache** button for Photos. The effective ways to reduce Photos storage are: **1)** Empty the **Recently Deleted** album (photos sit there for 30 days using space); **2)Restart your iPhone** to clear system caches; **3)** Turn **iCloud Photos off and back on** to rebuild the local cache; **4)** Enable **Optimize iPhone Storage** so full originals live in iCloud. Most "Photos cache" space is actually photo files, not cache.

## Method 1: Empty Recently Deleted

### 1 Open the Photos App

Tap the **Albums** tab at the bottom, then scroll down to **Utilities**.

### 2 Open Recently Deleted

Tap **Recently Deleted**. On iOS 16+, this album is locked — use Face ID or Touch ID to unlock.

### 3 Delete All

Tap **Select** in the top right, then **Delete All** in the bottom left. Confirm. This permanently removes everything in the album and frees the space immediately.

## Method 2: Restart Your iPhone

### 1 Force Restart

Press and release Volume Up, press and release Volume Down, then press and hold the Side button until the Apple logo appears. A full restart clears RAM-level caches and many app caches, including some Photos temp files.

## Method 3: Rebuild iCloud Photos Cache

This is the most thorough option. It can temporarily use more data as your library re-syncs.

### 1 Turn iCloud Photos Off

Go to **Settings > [your name] > iCloud > Photos**. Toggle **Sync this iPhone** off. Choose **Remove from iPhone** if prompted — full originals stay in iCloud.

### 2 Restart the iPhone

Give iOS a few seconds to process the change, then restart the phone.

### 3 Turn iCloud Photos Back On

Return to **Settings > [your name] > iCloud > Photos** and toggle it back on. Enable **Optimize iPhone Storage** so only smaller previews download. Your library will re-sync with a fresh cache.

## Method 4: Enable Optimize iPhone Storage

This is the single best way to reduce Photos storage long-term.

### 1 Open Photos Settings

Go to **Settings > Photos**.

### 2 Select Optimize iPhone Storage

Under iCloud Photos, tap **Optimize iPhone Storage**. iOS will begin replacing full originals with smaller, device-optimized versions. Over a few hours on Wi-Fi, you can recover many gigabytes.

## Frequently Asked Questions

### How do I clear the Photos cache on iPhone?

No explicit cache button exists. Empty Recently Deleted, restart iPhone, toggle iCloud Photos, or enable Optimize Storage.

### Why does the Photos app use so much storage?

Actual photo and video files, previews, thumbnails, Memories, and Recently Deleted. Most of it is photos themselves, not cache.

### Does restarting iPhone clear the Photos cache?

Partially. It clears RAM caches and some disk caches but does not delete photo files.
