How to Clean Junk Files on Your iPhone

They say one man’s trash is another man’s treasure, but when it comes to junk files on iPhone, there’s nothing attractive or enticing about them. They take up both storage and system space that you may need for more important items. Let’s look at what these files consist of and walk through several methods to clean junk files on iPhone.

Identifying Junk Files on Your iPhone

What exactly are junk files on iPhone? The items listed below are normally considered “junk.” Take a look at each item and its description to decide if it’s something you can remove.

To check your storage settings and see what consumes the most space, open the Settings app, choose General, and select iPhone Storage.

View the graph at the top for a summary of used and available storage, the list of apps sorted by size, and the exact amount of System Data usage at the bottom. System Data includes items like caches, logs, and other resources.

Methods to Clean Junk Files Manually

Once you take a peek at your device storage, it’s time to clear the junk from your iPhone. If you’re ready to make room for the items you really need, here are several methods for de-junking your device.

Method 1: Restart Your iPhone

When you restart your iPhone, this removes the temporary files, or caches, that consume system storage. While the system data refills as caches are created and resources are needed, and your system normally takes care of temporary files itself, you can manually free up a bit of space temporarily.

Restart your iPhone using the steps below depending on your device model: 

• iPhone X, 11, and later: Press and hold the side button (right) and either volume button (left).
• iPhone 6, 7, 8, or SE (2nd or 3rd generation): Press and hold the side button (right).
• iPhone 5 and earlier or SE (1st generation): Press and hold the top button.

When you see the restart screen, drag the power-off slider. Your iPhone should turn off after a few seconds.

To turn your device back on, press and hold the side or top button until you see the Apple logo. 

Method 2: Clear App Cache

To clear the cache junk on iPhone without restarting your device, you can manually remove those temporary files created by apps. You’ll find that caches are normally used by web browsers, social media networks, media streaming services, and cloud-based tools.

To begin, Apple provides you with a way to clear the cache for Safari; just follow the steps below.

1. Open the Settings app and select Safari.
2. Tap Clear History and Website Data.
3. Choose All History and All Profiles to clear all cache.
4. Select Clear History.

For apps like Facebook, TikTok, Chrome, Firefox, YouTube, or others that use temporary files, you’ll need to check each app’s settings for a cache-clearing option. 

As an example, here are the steps to clear cache in the Google Chrome app:

1. Open the Chrome app and tap the three dots on the bottom right.
2. Select Clear Browsing Data.
3. Optionally, choose a Time Range at the top of the subsequent screen.
4. Choose Cached Images and Files along with any other data you’d like to remove. 
5. Tap Clear Browsing Data at the bottom and again in the pop-up window to confirm.

Method 3: Delete Large Message Attachments

Large attachments your friends and family share with you via Messages take up space. You can easily remove these photos, videos, and files after you save those you want to keep.

Follow these steps to remove large message attachments:

1. Open the Settings app and tap General.
2. Choose iPhone Storage.
3. Below Recommendations, select the option for Review Large Attachments. If you don’t see this option, select Messages in the list and you should see it there.
4. You can then review all large message attachments and have the option to select each one for a detailed view.
5. Delete the attachments by doing one of the following:
   • For individual attachments, slide one from right to left and tap Delete. 
   • For several attachments, select Edit on the top right, pick the attachments, and tap the delete (trash can) icon.

Method 4: Manage Your Photo Albums

One of the simplest ways to declutter your device of junk is by deleting duplicate photos. For instance, you may snap three or four photos of the same scene to make sure you get the perfect shot. Considering holding onto the best and deleting the rest using the Duplicates feature in Photos.

With this feature, you can review the sets of duplicate photos and then merge them to keep the highest quality pictures. The others are then moved to the Recently Deleted album in Photos.

1. Open the Photos app and go to the Albums tab.
2. Scroll down to the Utilities area and tap Duplicates. Note that you’ll see the total number of duplicates on the right.
3. Review the sets of duplicates for those you want to merge. If necessary, you can select a photo in the set to see a larger view first.
4. Choose Merge on the right to combine a set of duplicate pictures. 
5. Tap Merge X Exact Copies or Merge X Items to confirm.

Although this is the simplest method, there are more ways to remove duplicate photos on iPhone you can check out.

Method 5: Clear Your Downloads Folder

Once you download media or files and then work with them or save them, you may be able to get rid of the original downloads. You can review the items in your Downloads folder for those you can safely delete from your iPhone.

1. Open the Files app and go to the Browse tab.
2. Select iCloud Drive or On My iPhone depending on where you normally save your downloads. You can also delete downloads from both locations.
3. Choose the Downloads folder.
4. Tap the three dots on the top right and pick Select. Remember, you can open any item for a closer look before you delete it.
5. Mark each download you want to remove or use Select All on the top left for all files.
6. Select the Delete icon (trash can) at the bottom to remove the selected items.

Method 6: Remove Unnecessary Apps

Have you ever downloaded a game you only played once or an app you decided you didn’t like? If so, it’s time to get rid of these space hogs that can easily be considered junk if you don’t use them.

To delete an app, long-press its icon on your Home screen and then, do one of the following:

• Choose Remove App and then Delete App. 
• Keep pressing the icon to enter jiggle mode. Select the minus sign on the top left corner of the icon and tap Delete App. Continue this process to remove additional apps and select Done when you finish. 

Confirm the removal by tapping Delete.

Method 7: Delete Duplicate Contacts

To effectively clean junk files on your iPhone, one simple yet often overlooked method is to delete duplicate contacts. Although these duplicates don’t consume much storage space, they can clutter your contact list and cause confusion. Here’s how you can easily remove them:

1. Open the Phone app on your iPhone.
2. Tap “Contacts” at the bottom center of the screen.
3. After a brief moment, your iPhone will identify the number of duplicate contacts you have.
4. Tap “View Duplicates” to see the list of duplicate entries.
5. You can then either tap “Merge All” to merge all duplicates at once or select specific contacts to merge individually.
6. Finally, hit “Merge,” and you’re done. By following these steps, you can streamline your contacts and make your iPhone a bit more organized.

Use Software to Delete Junk Files on Your iPhone

If you find that your iPhone’s cleaning capabilities aren’t enough, you can use a third-party iPhone junk cleaner. Apps like those listed below can assist with photos, videos, caches, and more. For example, you can delete duplicate pictures using the built-in Photos feature on iOS, but the feature doesn’t help remove similar photos.
