– From Apple Community

For years, Apple users on various platforms have been frustrated by the iOS bug that eats up a large amount of their device’s space, which is why the iPhone shuts down since the storage is full. But don’t worry. This article will detail this issue and offer a reliable solution – iMyFone Fixppo，to help you resolve it.

• iOS 18: New Features and Their Impact on Storage

iOS 18 introduces a range of exciting updates that bring your iPhone experience to the next level. The first is enhanced graphics, which are designed to make everything look sharper and vibrant. The second is refreshed apps that have more functions and improvements. What’s more, the system files have become larger to make the performance stable and more fluent.

However, as the graphics get better, and apps become more versatile, they come with a trade-off: more storage space. Your available storage would deplete faster when your device hasn’t had a storage upgrade, making it harder to keep everything running smoothly.

• Why iOS 18 Might Cause Your iPhone to Shut Down Due to Full Storage

iOS 18’s new enhancements push your iPhone to work harder than ever to meet the system’s demands. The more demands, the more storage is required, and then your iPhone might struggle to keep up, leading to unexpected shutdowns.

One user from Reddit once said that his iPhone System Data usage jumped up from 8 to 35 GB after installing iOS 18, and his iPhone began shutting down. His teammate saw an even greater increase to 140 GB, which also led to shutdowns. They are not alone. Another user mentioned facing similar issues with previous versions like iOS 17.3-17.5, even though he hadn’t encountered this problem before.

• Quick Fixes to Manage Storage on iOS 18
• Method 1. Optimizing Storage

First, go to Settings to check how much storage System Data is using. Here you can also see clearly how much space each app is taking. Offload those apps you rarely use, and this step will remove the app but keep its data, so you can reinstall it later without losing anything.

Moving your photos, videos, and other files to iCloud is also a great way to free up space on your iPhone.

• Connect your phone to your PC.
• Open iTunes or the Finder.
• Selected your device from the list.
• Pick the files or folders.
• Transfer them carefully to your iCloud.
• Method 2. Manual Cleanup

Another more hands-on approach is deleting the unwanted photos, videos, or unnecessary files one by one.

• Open the “Photos” app.
• Go through your albums and pick those you no longer need.
• Click “Select” and choose the items.
• Hit on the “Trash can” symbol to move them to “Recently Deleted”.
• Tap “Delete” in the pop-up window.

While these manual methods can help you, they might not fix deeper system issues caused by iOS 18. If you’re still facing problems with your storage, it could be a sign of a more complex issue that might require additional solutions.
