Not having enough storage on your iPhone can slow it down and prevent you from installing new apps or updates. If you often see “Storage almost full” alerts, it’s time to clean up your iPhone.
In this guide, we’ll show you the best ways to free up storage on your iPhone and keep it running smoothly.
Check your storage usage
Before you delete anything, you need to understand what’s taking up space on your device.
To check storage:
Go to Settings → General → iPhone Storage
Here you’ll see a breakdown of how much space apps, photos, system data, and more use.
Delete unused apps
Many users have apps they no longer use. These apps are taking up valuable storage space.
Scroll through your apps and remove anything you don’t need.
To delete apps:
Press and hold the app icon → tap Remove app
Disable unused apps
If you don’t want to delete an app completely, you can disable it. This will remove the app but keep its data.
To enable this:
Settings → App Store → Disable unused apps
This is useful for apps that you rarely use but don’t want to lose data on.
Clear photos and videos
Photos and videos are usually the biggest storage consumers. Deleting unnecessary media can free up a lot of space.
You can:
- Remove duplicate photos
- Delete old screenshots
- Remove large videos
- Also, don’t forget to clear the Recently Deleted album.
Use iCloud storage
Instead of storing everything locally, you can use iCloud to save space.
Enable iCloud Photos:
Go to Settings → Apple ID → iCloud → Photos
Then Optimize iPhone Storage.
This keeps smaller versions of photos on your device while storing full versions in the cloud.
Clear Safari Data
Browsing data can build up over time and take up unnecessary space.
To clear it:
Settings → Safari → Clear History and Website Data
This can help free up storage and improve browsing performance.
Remove Unwanted Music
Multimedia, such as audio and video files, takes up a lot of space. If you use Apple Music, make sure to delete any audio or video files you store locally for offline listening. Go to Settings > General > [Device] Storage > Music, swipe left on any albums or tracks you don’t want, and delete them. Press the Edit button to delete multiple entries at once. You can also do this in the Music app from Library > Downloaded.
Delete messages and attachments
Messages, especially those with photos and videos, can take up a lot of space.
Go through old conversations and delete any unwanted messages or large attachments.
Check your total usage
First, estimate how much space you have. Go to Settings > General > [Device] Storage. At the top, you’ll see a color-coded bar chart that shows how much space each app category is taking up on your device. This can include apps, messages, and photos. Keep in mind that a small portion of your device’s memory will always be used by the operating system.
You don’t need to delve into these numbers. To update iOS, you’ll typically need up to 10GB of free space. If you want to have enough space to take new photos and install new apps, give yourself at least 2GB of free space.
Remove downloaded media
Apps like YouTube, Spotify, or Netflix allow offline downloads. These files can take up a lot of storage.
Open these apps and remove downloaded content that you no longer need.
Use Storage Recommendations
iOS provides automatic recommendations to free up space.
Go to Settings → General → iPhone Storage
Follow these suggestions:
Review large attachments
Enable inactive apps
Automatically delete old conversations
Why is privacy important when cleaning photos?
Your photo library is one of the most personal data sets on your phone – it contains your face, your family, your home, and your daily life. Before you hand it over to any cleaning app, consider how that app processes your images.
Cloud-based photo cleaners upload your images to remote servers for analysis. This means your personal photos travel over the internet and are processed on someone else’s infrastructure, creating risks around data breaches, unauthorized access, and unclear data retention policies.
Everything is processed locally on the device. Your photos never leave your iPhone. AiCleanerPro uses Apple’s Vision framework and Core ML to perform all of its analysis directly on your device – no internet connection required, no uploads, no cloud storage. Your photos are yours.
Why is my iPhone storage filling up so fast?
The average iPhone user has over 2,000 photos in their library. Research shows that about 30% of them are duplicates, near-duplicates, or similar photos that serve no purpose. This is where the bloat comes in:
Duplicate photos — Have you saved the same image twice from a conversation, upload, or download? Over months, these pile up invisibly.
Similar photos — Taking 5-10 photos to “get the right one,” but never deleting the rest.
Screenshots — Temporary screenshots of addresses, receipts, and memes that outlive their usefulness.
Burst photos — A single burst can generate 20-50 nearly identical images, each of which consumes all of your storage.
Chat Photos — WhatsApp, iMessage, and Telegram automatically save images to your camera roll, often without you realizing it.
Large Videos — A single 4K video recorded at 60 fps can exceed 400 MB per minute.
FAQ
Is it safe to delete duplicate photos?
Yes. Duplicate photos are exact or near-exact copies of images you have. Removing them does not affect the original. AiCleanerPro always keeps the best quality version and only suggests additional ones to delete. Since deleted photos remain in your Recently Deleted album for 30 days, you can recover anything you accidentally delete.
Will Photo Cleanup affect my iCloud?
If you use iCloud Photos, deleting photos from your iPhone also removes them from iCloud – and frees up iCloud storage. This is actually a double benefit: you get back space on your device and your iCloud plan. Keep in mind that deleted photos remain in Recently Deleted for 30 days before being permanently removed from iCloud.
Final thoughts
Keeping your iPhone’s storage clean is essential for maintaining performance and preventing issues. By deleting apps you don’t use regularly, removing media files, and using cloud storage, you can keep your device running smoothly.
Freeing up storage not only improves speed but also ensures that you always have room for important updates and apps.
