Clean the Cache

Over your iPhone's lifetime, cache files stored by apps increase steadily and can consume valuable space. Fortunately, you can find out which app's cache takes up the most space so you can erase it. Apps like TikTok, WhatsApp, and Spotify tend to be the biggest culprits.


  1. Go to Settings > General > iPhone Storage.
  2. You will see a list of files on your iPhone.
  3. You can now see which app is taking up the most space.
  4. Check which apps have taken up the most space on your iPhone.

Reduce Storage of TikTok

TikTok is one of the most popular video-sharing apps and is widely preferred by many. It is a great app, but on the flip side, its cache can take up considerable space on your iPhone. Fortunately, you can quickly minimize TikTok's storage consumption by clearing its cache.


  1. Open TikTok and tap Profile from the bottom right.
  2. Tap the three-line icon in the top right of your iPhone screen.
  3. A menu will pop up. Press Settings and Privacy.
  4. Tap Clear cache.
  5. Clear TikTok cache to free up storage space on your iPhone.

Reduce Storage of WhatsApp

WhatsApp is the most famous end-to-end encrypted messaging app. Since many people tend to share a lot of media via WhatsApp, it ends up hogging space on your iPhone. You can clear this storage by erasing WhatsApp media files that are no longer relevant to you. Alternatively, you can back up what you want and clean out the data.


  1. Open WhatsApp and go to Settings.
  2. Tap Storage and Data > Manage Storage.
  3. Press Larger than 5 MB, Forwarded Many Times, or pick a specific chat.
  4. You can either tap Select All to erase all items at once or delete individual items. To selectively clear files, tap the item or items you want to erase.
  5. Tap Delete. If you have chosen starred items, you can tap Delete All Except Starred or Delete All.
  6. Press Delete Item or Delete Items. If you have selected duplicate files, hit Delete Item and Any Copies or Delete Items and Any Copies.

You can also delete individual WhatsApp files via the search feature.


  1. Go to the Chats tab and swipe down to reveal the Search bar.
  2. How to erase WhatsApp files.
  3. Press Photos, Videos, or Documents.
  4. Select the file you want to delete.
  5. Tap Delete > Delete For Me.

Delete Spotify Cache Memory

Another storage hogging culprit is the Spotify cache which piles up the more you use the app. The good part is that you can delete the Spotify cache memory from within the app. But, it is important to note that despite the process differing in various OSes, they all start the same. If you are using iOS, this is how to delete the Spotify cache:


  1. Launch the Spotify app on your iPhone.
  2. Tap the Gear Icon in the top right corner.
  3. Select Storage.
  4. Tap Delete Cache.
  5. Delete your iPhone’s Spotify cache.

Delete and Reinstall the Apps

Some game apps consume plenty of memory on your iPhone, but you cannot find their cache. If you see such an app has taken up space, you need to delete it and then reinstall the app to reduce its storage consumption.


  1. Go to Settings > General > iPhone Storage.
  2. You will see a list of apps and how much space they consume. Apps are listed from the largest to the smallest in terms of space consumption.
  3. Select the app you want to uninstall, then tap Delete App > Delete App.
  4. To reinstall the app, go to the App Store.
  5. Tap your circular profile picture.
  6. Tap Purchased > Not on this iPhone.
  7. Locate the app you deleted and tap the download button to reinstall it.

Remove Unnecessary Apps

Removing unnecessary apps is also a convenient way to free up space on your iPhone. Any installed apps you don't use take up memory that you can use for other purposes. Uninstalling such apps is easy.


  1. Go to Settings > General > iPhone Storage.
  2. Remove unnecessary apps
  3. You will see a list of apps and how much space they consume. They are listed from the largest to the smallest in terms of space consumption.
  4. Select the app you want to uninstall, then tap Delete App > Delete App.

Delete the Messages

If you have not configured your iPhone to automatically erase messages after a certain period, it keeps a permanent copy. Even though deleting messages clears little space, it can help. Furthermore, texts with images can take up quite some storage. When removing messages, you can delete entire conversations or erase messages selectively.


To delete an entire conversation:

  1. Open the Messages app.
  2. Locate the chat you want to clear, then swipe left on it until you see Delete.
  3. Delete message conversations to free up space.
  4. Tap Delete, then tap Delete again in the popup window.

To delete one or more individual messages:

  1. Open the Messages app.
  2. Scroll through the messages and tap to open a conversation containing texts you want to delete.
  3. Locate the message you intend to erase, then tap and hold it for around three seconds.
  4. Tap More... in the popup window.
  5. Now you need to do one of the following:
    1. If the selected message is the only one you want to delete, press the trash icon in the bottom left of your screen, then hit Delete Message.
    2. If you want to delete multiple texts, select them by checking the empty bubbles on the left of the message. Then, tap the trash icon > Delete Messages.
    3. How to select and delete multiple texts.
    4. If you decide to remove all the messages, tap Delete All > Delete Conversation. This is the same as swiping left, as explained above.
