Step 1: Back up your iPhone

Always back up your iPhone before clearing system data to prevent data loss.

Backing up your iPhone is crucial because clearing system data might result in losing some personal data. You can back up your iPhone using iCloud or your computer. Just head to your settings, tap on your Apple ID, select iCloud, then iCloud Backup, and hit ‘Back Up Now.’

Step 2: Open Settings

Once you’ve backed up your data, open the Settings app on your iPhone. This is where you’ll find all the options for managing your phone’s storage and system data.

In Settings, scroll down and tap on ‘General’ to access further options.

In the General section, you’ll find various settings related to your iPhone’s overall functionality, including software updates, device information, and more.

Step 4: Tap on ‘iPhone Storage’

Within ‘General,’ find and select the ‘iPhone Storage’ option.

The iPhone Storage section will show you a breakdown of what’s taking up space on your device. You can see how much space apps, photos, messages, and system data are occupying.

Step 5: Clear ‘System Data’

Find ‘System Data,’ then tap on it and select ‘Clear’ to remove unnecessary system files.

The System Data will include cached files, logs, and other non-essential data. Clearing this out can sometimes free up a significant amount of space, depending on how much data has accumulated.

After you clear system data on your iPhone, you should notice that you have more storage space available. Your iPhone may also perform better since it’s not bogged down by unnecessary files.
