Learn how to clear iPhone memory and cache accumulated on your iPhone and iPad. Your devices will gain in storage space and performance! Jul 20, 2020 If you clear cache on iPad or iPhone, you will see a performance increase, and the “other” storage within your iPhone’s memory will reduce. But what is “other”? The “other” storage is an untouchable partition in your phone or tablet memory that’s specifically meant to house things like browser cache data as well as app data. Create Clear Memory Cache Shortcut. This is one of the easiest solutions to clear memory cache on.

With high-resolution photos and console-quality games, your iPhone storage fills up in no time. Even with a 128 GB model things can get out of hands fast. And if you’re using a 32 or 64 GB iPhone, chances are you’ll see that pesky “Storage Almost Full” alert much sooner.

Delete iphone memory cache

Luckily, there are lots of things you can do to clear storage on iPhone, both manual and app-powered, so let's take a look.

What you'll need:

  • Your iPhone
  • A photo cleaner app Gemini Photos
  • Your Mac
  • A macOS cleaner app CleanMyMac X
  • Internet connection

Why is my iPhone storage so full?

Your iPhone may be full of things you don’t really need. Since they take up a lot of valuable space, it’s important to find out what they actually are. Here’s how to check and manage storage on your iPhone:

  1. Go to Settings > General > iPhone Storage.
  2. At the top, you’ll see a color-coded bar showing how much space you have left, how much is taken up, and what's taking it up. The biggest categories are usually Photos and Apps, but that depends on your usage.
  3. Below there is a list of your apps sorted by how much space they take. You can tap on each app to see how much of that space is the app itself, and how much of it is the app’s Documents and Data.

Depending on how you use your iPhone, you might have a huge and bloated Photos app, bursting with photos and videos. Or it might be games and social media apps that are hoarding the most storage. Below are five easy steps you can follow to free up storage on iPhone regardless of your iPhone use.

How to clear storage on iPhone

Chances are, there’s a lot of unneeded clutter on your iPhone. And that’s actually good news. It means you can free up a significant chunk of space without deleting the things you want to keep. Here’s how to free up storage on your iPhone, step by step:

  1. Clean up your photo library
  2. Clear browser cache
  3. Clear app cache and other app data
  4. Delete attachments in Messages
  5. Delete offline content

Step 1. Clean up your photo library

If you’ve checked iPhone storage like we suggested above, you already know who the main space hogger is (looking at you, Photos). Of course, wiping your whole photo library clean is not an option, but there’s probably stuff you can get rid of:

  • duplicate photos, like those you downloaded twice
  • similar shots (like the five selfies you took so you can pick a good one)
  • photos of whiteboards, notes, checks, and things like that
  • screenshots you don’t need anymore
  • large videos you don’t like

You can go through your library and weed out these photos and videos manually, but a quicker and more convenient alternative is an iPhone app like Gemini Photos. Here’s how to free up some space with it:

  1. Download Gemini Photos and launch it. It will automatically start scanning your library.
  2. Go to Notes, Blurred, and Screenshots. This is where you’ll see screenshots, photos of text, and other useless stuff. All photos will be pre-selected, but you can deselect the ones you still need.
  3. Tap Delete All.
  4. Go to Similar. Sets of similar photos will be grouped and pre-selected, with the best photo in each set remaining.
  5. Review a set, select other photos if you want to, and tap Move to Trash to trash selected photos.
  6. When you’re done reviewing sets of similar photos, tap Empty Trash.
  7. Go through Duplicates, Videos, and Other to sort out the rest of your photo library.
  8. Finally, go to the Photos app, and scroll down to Recently Deleted.
  9. Tap Select, and then Delete All.

After a cleanup like this your library will shrink by a few gigabytes and become way easier to navigate.

Step 2. Clear browser cache

If you often use your iPhone to browse the web in Safari or Chrome, keep in mind that your phone may be storing caches and other data that you don’t need. And you'd be surprised how much space you can free up just by clearing your browser cache.

Here’s how to clear Safari cache:

  1. Go to Settings.
  2. Find Safari.
  3. Choose Clear History and Website Data.

If you use Chrome, follow these steps to clear its cache:

  1. Open Google Chrome on your iPhone.
  2. Tap Options > Settings.
  3. Scroll down and tap Privacy.
  4. Tap Clear Browsing Data.
  5. Choose which browsing data you want to clear (browsing history, cookies, cached images and files) and tap Clear Browsing Data.

Step 3. Clear app cache and other app data

Unlike browsers, most apps don’t give you access to their cache and other data they store, such as login data. And if you tap on each app at the top of that list in iPhone Storage, you’ll notice it has several gigabytes of so-called Documents and Data. Here’s how you clear that app data to get more iPhone storage:

  1. Before you start, make sure you remember your logins to various apps or have them saved somewhere.
  2. In Settings > General > iPhone Storage, tap on an app at the top of the list. This will often be a social media app like Facebook or Snapchat, a messenger, or a content app like YouTube or Spotify.
  3. Tap Delete App.
  4. Go to the App Store and reinstall the app.

Yup, unfortunately, this is the only way to clear cache and other app data for the majority of apps.

Step 4. Delete attachments in Messages

Texting isn’t just about text, right? You’re sending and receiving memes, GIFs, selfies, little videos of your cat falling off the couch in her sleep. All that content is stored on your iPhone even if you don’t save it to Photos, and if you text a lot it quickly adds up.

Here’s how to delete all your attachments in Messages to clear some iPhone memory:

  1. Go to Settings > General > iPhone Storage.
  2. Scroll down and tap on Messages.
  3. You’ll see a list: Top Conversations, Photos, GIFs and Stickers, and Other. Tap on the category that occupies the most space. Keep in mind that in Top Conversations, you’ll be deleting entire threads, not just the attachments. If you don’t want to do that, stick to Photos and other content.
  4. Tap Edit in the upper-right corner.
  5. Mark all attachments you want to delete.
  6. Tap the Trash icon.

That’s it! Space-hogging attachments are gone.

Step 5. Delete offline content

Memory

You probably consume a lot of content every day — music, videos, podcasts and what not. And if you save that content offline to be able to play it on the subway or during a long flight, you have quite a lot of leftovers piled up.

As a result, apps like YouTube, Netflix, and Spotify can take up several gigabytes of iPhone storage each. So why waste space on those Stranger Things episodes you downloaded back in 2017 and a long-forgotten playlist you never listen to anymore?

Let’s start with Netflix. Here’s how to delete Netflix movies and series you saved onto your iPhone:

  1. Open the Netflix app.
  2. Go to Downloads.
  3. Tap on the pencil icon in the top right corner.
  4. Tap on the red X to delete the video.

Next up, YouTube. To delete offline YouTube videos, follow these steps:

  1. Launch the YouTube app.
  2. Go to Library > Downloads.
  3. Tap on the three dots next to a downloaded video.
  4. Tap “Delete from downloads.”
  5. Repeat for each video.

Finally, to delete offline playlists or podcasts in Spotify, do the following:

  1. Open Spotify.
  2. Go to Your Library > Music > Playlists.
  3. The playlists you downloaded will be marked with a green arrow. Tap on a playlist like that.
  4. Tap on the green arrow icon below the name of the playlist.
  5. When a confirmation popup appears, tap Remove.
  6. Repeat for podcasts, if you have any saved offline.

You should also rummage around in Podcasts, Apple Music, and other entertainment apps you’re using. Once you’ve cleaned up all the offline content you don’t need anymore, you’ll see how much iPhone memory you’ve managed to recover.

How to prevent iPhone storage from getting full again

Just like your closet, iPhone storage will get full again, and you will have to go through the steps above every once in a while. But there are things you can do to manage your oh-so-limited storage more wisely and not have to do that major cleanup quite as often.

Store photos and videos elsewhere

Even after you’ve trimmed some fat off your library, chances are Photos still hogs a lot of iPhone space. What to do? Transfer your photos and videos to your computer or to the cloud

If you have a Mac, the easiest way is to connect your iPhone and sync all media files to the Mac. Then you can delete the originals from your phone.

Note that when you sync photos with your Phone, some of them stay cached on your Mac. This cache occupies space on your disk after the sync is done, so it’s better to clean it up. A utility like CleanMyMac X is an easy way to clear iOS photo cache (and it’s free to download). In just two clicks you’ll remove all the junk files from your Mac.

Alternatively, you can upload your iPhone photos to an online storage like iCloud. It’s pretty convenient, because iCloud Photos automatically syncs every photo and video you take to the cloud, so you can access your library from any device, as long as it has internet connection. You do have to pay for iCloud storage, though, because the free 5 GB won’t be enough for your whole photo library.

Here’s how to upload photos to iCloud:

  1. Sign in to your iCloud.com account. It’s the same as your Apple ID.
  2. Go to Settings on your device and select Photos.
  3. Turn on iCloud Photos.

Now your photos are automatically synced to iCloud, which means they'll be taking up space in iCloud, not on your iPhone.

Disable saving duplicate photos when shooting in HDR

On iPhones that don’t have Smart HDR, when you take photos in HDR, your iPhone saves two shots: the original picture and the processed one. You will save a lot of iPhone storage if you disable saving these duplicates. Just do the following:

  1. Go to Settings and select Camera.
  2. Disable Keep Normal Photo.

From now, only the HDR versions of your photos will be saved. That said, the previous HDR and non-HDR copies of your photos will remain, so do run your photo library through Gemini Photos to find those similar shots.

Stop storing messages forever

By default, your iPhone stores all the messages you send and receive … forever. This is convenient if you want to read your 2-years-old conversations, but not so convenient when you run out of storage because your brother sends you fifteen memes every single day.

To stop your phone from saving messages forever, follow these steps:

  1. Go to Settings and tap Messages.
  2. Scroll down to Message History and tap Keep Messages.
  3. Change Forever to 30 days or 1 year.
  4. You’ll see a pop-up message asking if you want to delete older messages, tap Delete to proceed.

Bonus tip to help you clean iPhone storage

In iOS 11 and later, Apple brings storage management tools to your device. This means that you get unique storage saving suggestions based on your iPhone. They include things like Reviewing Large Attachments and Conversations, Offloading Unused Apps, Saving Messages to iCloud, and others. Therefore, if you’re running iOS 11 or later, go to iPhone Storage and check out the recommendations.

We hope you found our troubleshooting guide helpful in tackling that annoying “Storage Almost Full” message. Enjoy taking new photos and never have to worry about lack of iPhone storage again.

When you first buy your iPhone or iPad, the feeling must be pretty amazing because you got a brand new device and it’s running fast. Later on, you may feel like things are sometimes not refreshing with new data, or that your storage space has gone away rather quickly.

Maybe cached files using more space than you would think, or maybe a specific app is having issues with cached data and can’t refresh with live data. In that case, you will need to clean out your iPhone’s memory, unwanted data, and caches. It’s time to find and remove cache, junk files on your iPhone or iPad and make it neat again.

Cache files can be found in many iPhone applications. For example, Safari uses a cache to store information about the sites you visited, and will use them in order to speedup your browsing experience. Even though this is crucial when it comes to making the site faster (by using less mobile data for already-loaded files), these cache files also take up storage space on your iPhone.

Cached browsing data aren’t the only thing that will create local files. When you download an app from the App Store, the size shown there doesn’t always represent the total space consumed. As you use the application, cache files may start to accumulate and use additional storage space. The more applications you have, the more files you potentially get.

Note that cache files usually don’t harm performance within an app, since it’s designed to accelerate an app… They may, however bloat the storage system, and they may require some processing/management depending on how the app or OS handle these files. In this tutorial, we will be showing you how to clear the cache files in your browser and applications.

We will start to clean out the cache of your Safari browser. This can easily be done from the stock Settings app.

  1. Go to Settings > Safari
  2. Scroll to the bottom of the page and choose Clear History and Website Data
  3. Confirm that you want to do this by tapping on Clear History and Data of Safari


When choosing this option, it will remove your History, cookies, and other browsing data. In other words, your pre-set credentials, the websites that you visited, and cache are not longer there anymore. Safari will be a brand new browser just like when you first open it.

Clear The App Cache on iPhone

There is no option on iPhone or iPad to clean a specific app’s cache unless you uninstall it entirely from your device, or unless a developer specifically included the feature into his/her app. When you uninstall an app from your iPhone, everything you have in that application, including cache and preferences will be deleted.

The best way to clean your iOS applications cache and junk files is to use a third-party app from the App Store called Battery Doctor (free). The first thing you need to do is head over to your App Store and install Battery Doctor app.

Once the app is installed on your home screen, briefly go through its introduction and get right to business. From the main screen of Battery Doctor:

  1. Head over to the folder that contain your application’s cache using the Junk tab on the bottom menu
  2. Simply tap on the Clean Up Cache button
  3. Read the caution message carefully and proceed by choosing Clean

Junk cleaning feature will remove some of your temporary files from applications, which may include game progress and cache data.

The cleaning process will start and when done, Battery Doctor will tell you its result. The report will show the total cleaned data and your available capacity.

Free The iPhone’s Memory

Another feature that I really enjoy from the Battery Doctor app is its Memory tab. You can use this feature to boost your iPhone or iPad, especially when it’s low on memory. This could be useful if apps that were open a long time ago, and are no longer being used right now, are taking RAM and possibly slowing down multi-tasking etc. In general, the OS is supposed to manage all this, but having some control can be good too.

As always, at the end of the boosting process, Battery Doctor will also show you a report of how much data it has got rid of from your device. Do keep in mind that freeing memory doesn’t always improve your iPhone’s performance or preserve battery life. Opposite result could happen if you are continuously using the Boost feature when your device is low on memory.

Note: don’t clear the memory too often. A number of apps and processes tend to reload themselves if they are not longer in memory. Reloading uses CPU and battery life.

One-click clear all App Cache with CacheCleaner tweak

The method that I showed you earlier in this post can be performed on any type of devices, I’m talking about jailbroken and non-jailbroken iPhone and iPad. However, for jailbreakers with access to Cydia on their iOS device, there is an easier way to clear your application cache without having to use Battery Doctor or desktop clients.

A well-known developer named Ryan Petrich has released a free package on his beta repo called CacheCleaner that allows you to quickly clear cache of a specific app.
