Similar to other digital devices, all your activities will be saved on your iPhone, such as the browsing history, photos and videos sent and received on social media, credits and progression of mobile games, and more. As time goes by, these data and files will become large and take up lots of space. That can cause problems and slow down your iPhone performance. This guide explains how to effectively clear the cache on your iPhone and free up space.

Part 1: What is Cache?

Before covering the how-to, let’s discuss what does clear cache mean. The cache is small bits of information stored on your internal storage. It acts as short-term memory and helps your iPhone run efficiently. The cache data on iPhone include:

Browsing history. When you access the internet in Safari, Chrome, or other browsers, the HTML files and web pages that you visited will be saved as browsing history. Then iOS can load them quickly when you return to the websites.

App cache. Plus, all apps you download and access on your iPhone create their own cache. TikTok, for example, saves the videos you have viewed. Moreover, mobile games keep your data too so they load fast the next time.

System cache. iOS also produces and maintains cache data to keep the system running normally.

While you cannot find a cache folder that you can simply empty on your iPhone, it does cost a considerable amount of storage space.

Part 2: Why Clearing Cache is Beneficial

Although cache data speeds up tasks and enhances your experience, it can take space and cause various problems. The main reasons why you should delete cache on your iPhone from time to time include:

1. Free up storage space. As mentioned previously, cache files take up space on your iPhone. Regularly clearing the cache can reclaim significant amounts of storage capacity for installing new apps or storing media files. You also need to clear caches on your Mac.

2. Improve iOS performance. Accumulated cache data can slow down the launch time of apps and the load time of websites over time. Moreover, that can cause sluggishness in certain apps. Clearing cache optimizes iPhone performance.

3. Fix software glitches and app bugs. Too much cache data can lead to issues and errors, like apps crashing, files corrupted, and more. Clearing the phone cache is a crucial step in troubleshooting.

4. Enhance privacy and security. Cache data can store lots of sensitive information, like your login credentials, credit card password, browsing history, and more. If someone else accesses the data without authorization, it poses a potential privacy risk.
