Everything You Need to Know About Clear Cache on Android and iPhone

In the present world of swift digital transformations, smartphones are always with us, helping us to organize work emails plus keep updated on social media (among many other tasks). However, with time these convenient gadgets can become slow and uncooperative— typically due to a pile-up of app cache. Should you observe that your Android phone is not functioning as smoothly as it ought to be— clearing the app cache may be what you need. Through this article, we will look at how to clear app cache; also why such a simple act of maintenance can play a critical role in keeping your device performing optimally (besides giving you more free storage space).

How to clear App Cache

A slow performance issue on a mobile phone or tablet can be easily resolved by trying some common steps to detect and correct the problem. Just shutting down your device and turning it back on can fix many issues. An additional common method to improve performance or, at the least, free up extra storage on an Android device is to clear an app's cached data and erase Chrome's cached data for visited websites.

What Is Cached Data?

Information cached by the browser would be stored on the device in order to access it later Should you want to access a site that you’ve visited previously, the information needed for that will be available locally on the device, rather than needing to go back to the main server. This also holds good for data on apps – anything that could be accessed and used repeatedly can be transferred to a quick-access location to ensure that future navigation is smoother and faster. So, caching is a common practice in computing, designed to work on the same principle, where data that you are more likely to retrieve again and again will be stored temporarily on your device or within the application, to speed up access and enhance performance.

Purpose: The main goal of caching is to reduce the time it takes to access data. By storing copies of frequently accessed information, a system can avoid the slower process of retrieving the same data from its original source repeatedly.

Types of Caches:
  • Browser Cache: Stores web page resources like HTML files, images, and scripts on your local device to speed up loading times for websites you visit frequently.

  • Memory Cache: Also known as RAM cache, it stores data that is frequently accessed by the CPU to speed up processing tasks.

  • Disk Cache: Utilizes a portion of the hard drive to store frequently accessed data, helping to reduce access times compared to retrieving from the main storage.

  • Application Cache: Specific to applications, storing data that the app frequently needs, reducing the need to fetch this data repeatedly from a remote server or the device’s main storage.


Improved Performance: Faster access to data improves the overall speed and performance of applications and systems.

Reduced Load Times: For web browsers and apps, cached data reduces the load time of web pages and functionalities.

Lower Network Traffic: By storing data locally, caching reduces the amount of data that needs to be transmitted over a network.

  • Storage Use: Cached data takes up space on your device, which can become an issue if not managed properly.

  • Outdated Information: Cached data may become outdated if the original data changes but the cache does not update promptly, potentially leading to inconsistencies.

  • Security and Privacy: Sensitive information stored in cache can pose security risks if not properly managed or if accessed by unauthorized users.

Management: Most systems and applications provide options to clear or manage cached data. Clearing cache can resolve issues related to outdated data and free up storage space.

Cached data is a crucial aspect of modern computing that enhances performance by temporarily storing frequently accessed information, but it requires proper management to avoid potential drawbacks.

What information does it store?

Cached data can store various types of information depending on the context and the specific cache type. Here are some examples of the kinds of information that different types of caches store:

Browser Cache:

HTML Files: The structure and content of web pages.

CSS Files: Stylesheets that define the appearance of web pages.

JavaScript Files: Scripts that add interactivity to web pages.

Images and Videos: Media content used on web pages.

Cookies: Small pieces of data used to store user preferences and session information.

Memory Cache (RAM Cache):

Program Data: Frequently accessed data and instructions from currently running applications.

Operating System Data: System libraries and kernel information that need to be quickly accessible by the CPU.

Application Cache:

User Preferences: Settings and configurations that a user frequently changes or accesses.

Temporary Files: Intermediate data that applications need to store temporarily during operation.

Offline Data: Data that allows applications to function without an active internet connection, such as emails or documents.

Disk Cache:

File System Data: Metadata and content of files that are frequently read or written.

Application Data: Data from applications that benefit from fast read/write access, such as database indexes and frequently used documents.

Content Delivery Network (CDN) Cache:

Static Assets: Images, stylesheets, scripts, and other resources that don’t change frequently and are distributed across multiple servers to reduce load times.

Database Cache:

Query Results: Results of database queries that are likely to be requested again.

Index Data: Frequently accessed indexes that help speed up database searches.

CPU Cache:

Instructions: Frequently executed instructions that the CPU needs to process.

Data: Frequently accessed data required by the CPU for executing instructions.

Each type of cache aims to store data that is frequently accessed or costly to retrieve from the original source, thereby improving the performance and efficiency of computing tasks.

Why should you clear the app cache?

Clearing an app cache can be beneficial for several reasons. Here are some of the key reasons why you might want to clear the cache of an application:

  1. Free Up Storage Space

  2. Resolve Performance Issues

  3. Update Cached Data

What happens when you clear cache?

Flushing an app’s cache deletes all the temporary files stored by that app. This freed up storage space on your device. It may also speed up the app, especially if it had caches of old or corrupt data. This could be particularly true for apps that need to track your location, like maps. Having stale data would make the app work poorly. By clearing the cache, you can make sure your app gets the most updated information the next time you use it (and possibly make it load slightly slowly for that initial trip). Clearing the cache won’t affect any of your own data or preferences – the app is just being reset by removing some bits of programs that don’t matter to your use of the app. Oh, and it might fix whatever hiccup was going on with the app.

How often should you clear cache?

How frequently you should delete the cache on an Android phone relies on your usage and the specific applications that you use. It is generally good to clear the cache when you have performance problems such as slow running apps, erratic ones or those which frequently crash. At the same time, if your device has fewer storage spaces left, it will be helpful to clear cache as this can create extra spaces especially where data-intensive applications like social media and streaming services are concerned. As part of regular maintenance procedure, clearing cache every few months helps to avoid pile up of unnecessary files keeping performance optimal; besides it also makes sense to clear out the cache after major app updates in order to avoid compatibility issues.

Though there’s no need for constantly cleaning off all caches, this guideline may help keep a smooth running of your machine.

Well if we talk about average then you can clear cache every few months But don’t clear it too frequently because it could have the opposite effect.

Why not use a third-party app cache cleaner?

To free up space and speed up your Android, consider using a third-party app cache cleaner; it is however not without its share of drawbacks.

Firstly, these apps often require extensive permissions to access your device's data, raising privacy concerns. These kinds of applications may gather and use confidential data without your permission.

Secondly, some third-party cleaners may include adware, malware, or other unwanted software, which can compromise your device's security and stability.

Moreover, Android devices already have built-in tools for managing cache and storage, which are generally effective and safer to use. The native tools used in this case work well with the OS’s that reduce unintended consequences like crashing of the app or losing data.

On top of that frequent cleaning of caches can slow down an app at first because they will be required to rebuild their caches again thus defeating the intended purpose.

Therefore while third-party cache cleaners might promise convenience, it is usually better to rely on Android’s own inbuilt tools for managing your device’s cache and storage as they are more reliable.
