What Is Cached Data And How To Clear Cache on Android

With the increased technological advancements, day after day we come across new terms that we really don’t know what they mean. If you are a smartphone user or a PC user, you must have interacted with the phrase “Cached Files”. Maybe a support team of a website you were trying to visit advised you to clear them after numerous failed attempts to access the site or an Android manual landed you there when trying to troubleshoot your Android phone.

Clear Cache on Android.

Here is the truth; mobile phones were first introduced to ease communications through making calls and sending texts (You can schedule text messages on Android with these tricks). Today, they do more than that. We rely so much on our mobile phones for birthday or appointment notifications, surfing through the internet and using other apps that not only make our lives easy but also help us run our businesses smoothly. And the point is, every device that connects to the internet uses cached data in one way or the other.

PART 1. What is Cache?

Is cached data important? To easily make you understand the meaning of cache, we will use a practical example to define the cached data meaning. Imagine visiting a restaurant in town for the first time. Here is what your brain will do; It will register and store the route in your mind so that when you visit the restaurant again, it will be easier and quicker.

That’s the exact same thing that happens with cached data. When you use your Android smartphone browser to visit a website or an app, it stores some information (the route) in the form of cache in the device memory. The next time when you visit the same website or app using the same device, it is easier and quicker for the device to access it because your phone already has the route (cached data) stored when the website or the app was visited the first time.

PART 2. Why Do Cached Data Exist?

The primary reason why cached data exists is to reduce the loading time. Cached data files in Android devices exist for apps you regularly use and the websites you regularly visit using your smartphone. If the device already has the memory of the layout of the website or app stored in the form of cached data, it will not have to waste time loading the exact same data once again. This helps in increasing the process of loading the website or the app.

Cached data can be helpful for smartphones and computers but the problem is that they eat up the space on your device. Cached data on your device can be essential for the websites and apps you use regularly but a waste of space for those sites that you only visit just once. With time, it may get corrupt or even interfere with how you visit the same website on your device. And then you will begin to receive some of the common HTTP error codes like 500 when you try to visit a website.

PART 3. Why Should You Clear the System Cache?

System cache has all the data for all the apps you have used and all the websites you have visited on your device. There is also a chance that there still exists data of an app you may have uninstalled or a social media post or image that you already viewed and you are not opening again. It is therefore advised that you should clear the system cache every now and then so as to free up some space on your Android device or tablet. In this way, you will not be having trouble with your device system failing most of the time.

An Android device or tablet may have stored lots of data in the system cache and continuously need eve much more space. It is therefore unnecessary to give away essential storage space to system cache.

Is it OK to clear cached data, and what does it mean to clear the cache? Cache clearing is also an important routine in the troubleshooting processes to resolve a number of problems that may be a result of stacked and corrupted cached data, for example, the “Unfortunately, your app has stopped” error. It is important that you understand that all Android apps, whether they are system apps or third party apps will have cached data on your android device. And since cached data is automatically created and does not include any important data, taking some time to clear the cache for an app or the whole device is totally a safe thing to do. It will not harm your device.

We have been experiencing better updates on Android versions and for that matter, most of the time you may not need to handle system cache on your own. Android systems usually manage system cache very well. Android devices manage data from the apps very diligently. That is, as an Android user, you will not have to worry about handling cached data on your Android device manually. However, when your device begins to face issues and the manual asks you to clear cache while trying to follow some troubleshooting steps, I highly advise that you consider doing so.

Once cache has been cleared, you will notice a slight change in the speed at which the app or website will be loading a little slower for the first time. That’s because cached data will be created once again. Once the cached data has been recreated and stored, you will notice that accessing the website or the app the subsequent time is smoother and faster.
