What is App Cache?
App Cache is a reserved memory space on iPhones that stores temporary files, scripts, and images generated by apps, helping them to load and run smoothly. This memory does not include login credentials, custom settings, or downloaded files.
Over time, the accumulation of the app cache can slow down the phone, making it necessary to clear the cache regularly. Clearing cache, cookies, and hidden junk files is beneficial for all iPhone models. Manual restart is also helpful, as it can clear temporary files and fix bugs.
Third-party apps like PhoneClean can make the process of clearing the cache easier and quicker. Therefore, it is important to understand the benefits of clearing the app cache and learn how to do so without deleting the app.
How to Clear Cache on an iPhone without deleting the app?
Various options are available for clearing temporary files from an iPhone. These options include:
- Manual restart: This can be done via the Settings application or the power button. Both methods shut down the phone and clear temporary files.
- Third-party applications: Applications like PhoneClean can be used to connect the iPhone to a computer, scan, and clean the cache.
- Deletion and reinstallation of applications: Deleting and reinstalling an app can clear its cache. This can be done through the App Store or the storage section of the General tab in Settings. However, users should consider which apps have the highest amount of cached memory to focus on, as reinstalling apps can be tedious.
Clearing temporary files can improve an iPhone’s performance and free up memory.
How to Clear Cache on an iPhone with Third-Party Apps?

Third-party applications can provide a more efficient method to clear cached memory from iPhones. PhoneClean is an example of a third-party iOS application that offers a quick and easy way to clear cache. It can be downloaded to a computer and then connected to the iPhone.
Once connected, the app will scan the device and clean the cache. This process can be completed in a few minutes, making it a much faster and less tedious option than deleting and reinstalling apps.
Additionally, third-party apps can offer more options and customization compared to the manual restart process. For example, PhoneClean can identify apps with high App Cache and target them for deletion.
Despite the convenience of third-party apps, users should always be mindful of the potential security risks of using these types of applications.
