In this digital era, most people cannot live without their mobile phones in their daily lives, and the apps on your phones are countless and play various roles, but in this way, they will occupy a lot of memory. Some users free up memory by regularly cleaning out unused applications, but what about users who can't delete them? The best way to do this is to clear your iPhone application cache without deleting it. This is a process that can be implemented in a few simple steps.

Part 1. Why Should You Clear App Cache on iPhone

When using your iPhone daily, application memory is consumed by many caches and temporary files, causing the device to slow down, run slowly, and even affect your battery life. Here are a few key reasons you must regularly clean iPhone application cache.

• Improve Equipment Performance

Frequently used applications generate large amounts of cache when running in the background, slowing down the system's responsiveness. Regularly cleaning out the app cache can make your iPhone run more smoothly.

• Increase Storage

Many applications use a lot of memory to store unnecessary temporary files and caches. Clean up these data to release more storage space and give you more room to store photos, videos, and other important documents.

• Extend Battery Life

A high memory footprint can cause the iPhone's processor to work frequently, which increases power consumption. As background processes accumulate, the battery drains significantly faster. Cleaning the iPhone application cache improves system performance and reduces power consumption, thus extending battery life.

Part 3. How to Clear Cache of Individual Apps

If you don't want to use third-party tools, the iPhone also offers a way to clean the cache of specific apps directly. Some apps offer a built-in cache cleanup option that lets you clear directly from the app Settings, but iOS's one-click cache cleanup function is more convenient.

Step 1. Open Settings > General > iPhone Storage.

Step 2. Here, you can see all the installed apps and their storage space; find the app that takes up a lot of storage space and click.

Step 3. Whether you click on a social app like Spotify or WhatsApp, you can see the size of the app itself and additional documents and data. Clicking the Offload App button clears all WhatsApp cache but doesn't delete what you've stored in the cloud.

Part 4. How to Clear iPhone Browsing Cache
