Keeping your iPhone running at peak performance requires more than just the occasional restart, it means regularly clearing out the digital clutter that builds up over time.
Cache files from apps and websites accumulate in the background, gradually eating into your storage space and slowing down your device.
This becomes especially important when you're preparing to install major updates like iOS 26 beta, which needs plenty of free space and a clean system to run smoothly.
Clearing your iPhone's cache is a simple maintenance task that frees up storage, improves app performance, and reduces the chance of conflicts with new software.
Whether you're troubleshooting issues or preparing for the latest iOS beta, a quick cache clear can make all the difference in your phone's responsiveness.
Why you should clear cache before installing iOS 26 beta
Beta software is less stable than final releases, so your device needs every advantage to run smoothly.
Old cache files can conflict with new features, causing crashes or performance issues that make it hard to tell if problems stem from the beta itself or leftover data.
Beta versions also require several gigabytes of free storage for installation and operation.
Cache files from browsers, apps, and system processes can easily consume space that could be better used by the new software.
Clearing cache before installation establishes a clean baseline, making it easier to identify genuine beta bugs versus issues caused by digital clutter.
