Free Up iCloud Storage on iPhone: A Step-by-Step Guide

Introduction / Why This Is Needed

iCloud is a convenient way to synchronize data across all your Apple devices. However, the free plan is limited to 5 GB, and with active use, storage can fill up quickly. When iCloud is full, automatic backups, photo and document synchronization, and some app features stop working. This guide will help you free up space in iCloud on your iPhone or iPad without losing important data. After following the instructions, you'll have free space for new files and uninterrupted operation of Apple services.

Requirements / Preparation

Before you begin, ensure that:

1. You have a device running iOS 15 or later (or iPadOS 15+).
2. You are signed in to your Apple ID (Settings → your name).
3. You have a stable Wi-Fi connection (recommended for uploading/deleting large files).
4. You are prepared to temporarily disable backups if you need to delete old copies.

Step-by-Step Instructions

Step 1: Check Your iCloud Storage Usage

First, you need to understand what is taking up space.

1. Open Settings on your iPhone/iPad.
2. Tap your profile at the top (the circle with your avatar and name).
3. Select iCloud.
4. Scroll down and tap Manage Storage (or iCloud Storage).

You will see a chart breaking down data by type: Backups, Photos, iCloud Drive, App Data, etc. Pay attention to the largest sections—these are what we will clean up.

Step 2: Delete Old Device Backups

Backups often take up huge amounts of space, especially if you haven't deleted old ones.

1. In Manage Storage, find the Backups section.
2. You will see a list of devices for which backups exist. Select a device you no longer use (e.g., an old iPhone).
3. Tap Delete Backup → Delete.
4. Important: If you want to delete the backup of your current device, first disable backup for it:
   • Go back to Settings → your name → iCloud → iCloud Backup.
   • Turn off the iCloud Backup switch.
   • Now return to Manage Storage and delete the old copy.
   • After deletion, turn backup back on.

Step 3: Manage App Data

Many apps (messengers, editors, games) store their data in iCloud. Unnecessary files often accumulate there.

1. In Manage Storage, scroll down to the App Data section.
2. Select an app that uses a lot of space (e.g., WhatsApp, Telegram, Photoshop Express).
3. You will see a list of documents and data. Delete what you don't need:
   • For messengers: old videos, audio, documents.
   • For editors: temporary files, old projects.
4. Tap Delete Data → Delete.

⚠️ Important: Deleting app data from iCloud will not delete it from your device, but it may become inaccessible on other devices. Make sure the files are not needed.

Step 4: Enable Photo Storage Optimization

Photos and videos are the most space-consuming data. The iPhone Storage Optimization feature automatically replaces originals with smaller versions, while full copies are stored in iCloud.

1. Open Settings.
2. Scroll down and select Photos.
3. Turn on the Optimize iPhone Storage switch.
4. If you previously used Upload Originals, enabling optimization will start the replacement process. This may take time, but space will be freed up gradually.

💡 Tip: After enabling optimization, check that iCloud Photos is turned on (Settings → your name → iCloud → Photos).

Step 5: Clean Up iCloud Drive

iCloud Drive is a general storage for documents you explicitly save to the cloud.

1. Find the Files app on your home screen.
2. In the iCloud Drive (or iCloud Storage) section, browse the folders.
3. Delete unnecessary files and folders:
   • Swipe left on the item → Delete.
   • Or tap Select at the top, mark several items, and tap the trash can.
4. Deleted files are moved to Recently Deleted in iCloud Drive. To free up space immediately, go there and delete them permanently.

Step 6: Consider Upgrading Your Storage Plan

If after all manipulations you still don't have enough space, you may indeed need a larger plan.

1. Go to Settings → your name → iCloud → Manage Storage.
2. Tap Change Plan (or Buy More Storage).
3. Select a plan: 50 GB, 200 GB, or 2 TB.
4. Tap Buy and confirm the purchase (the charge will be deducted from the card linked to your Apple ID).

💡 Tip: Disable unnecessary apps from backing up (Settings → your name → iCloud → iCloud Backup → manage backups). Often, apps that don't need syncing are enabled there.

Verify the Result

Go back to Settings → your name → iCloud → Manage Storage. You should see that the chart has changed and free space has increased. Also check:

• Backups are created without errors (Settings → your name → iCloud → iCloud Backup → Back Up Now).
• Photos are syncing (open the Photos app on another device).
• There are no extra files in iCloud Drive.

If space isn't freed immediately after photo optimization, give the system a few hours.

Possible Issues

Cannot delete the backup of the current device

Solution: Temporarily disable backup for that device (Settings → your name → iCloud → iCloud Backup). Then return to Manage Storage and delete the old copy. After deletion, turn the backup back on.

Photos aren't freeing up space after enabling optimization

Solution: Ensure that Optimize iPhone Storage and iCloud Photos are enabled in Photos settings. Also check that Upload Originals is not enabled (it overrides optimization). If the problem persists, restart your device.

App data won't delete or keeps coming back

Solution: Some apps (e.g., Google Drive, Dropbox) store data on their own servers, not in iCloud. Delete files through the app itself. Also, check if the app has a "Sync with iCloud" option—disable it if not needed.

Space fills up again quickly after cleaning

Solution: Enable Photo Storage Optimization and disable unnecessary apps from backing up. Also, regularly check Manage Storage (once a month).
