How to Clear iPhone Cache And Data

Whether you are an Android or iOS user, you might have encountered a low-speed issue in both cases that seem quite frustrating; although many people associate this issue to Android phones only but this is equally common in iOS devices too. In this entire discussion, we will elaborate on the relative issue with IOS devices only, so here the question may arise what causes iPhone speed fall primarily?

Cause of iPhone’s low performance

Many iPhone users presume this sort of performance degrades in their mobile devices as a result of outdated software or model, but that is not a reasonable cause.

You may already be familiar with the term “cache & cookies” as most of us spend maximum time in internet browsing. When we access a particular site for the first time, the device browser saves some related information in its cache storage so that the stored data can be retrieved more quickly on your next attempt to access the same website.

Actually, such a process of saving cache data is supposed to improve the user experience by speeding up the browsing process. But this cached data your IOS devices stores often impacts the performance badly and subsequently slows down its operating speed because it also consumes a lot of device Ram.

So, in order to improve the phone’s speed and performance, you don’t need to upgrade your phone; instead, you might require to clear out the cache and cookies stored on your iPhone to free up the unnecessarily occupied space.

To do so, you must need to be familiar with how to clear cookies on iPhone, but this seems quite problematic for many iPhone users as they often have the least knowledge on iPhone clear cookies or cache processes.

How to clear iPhone cookies & cache?

When it comes to clearing the cookies or cached data on your iPhones, the iOS or iPhone devices suggests various ways in this regard: some of the quick and effective methods have been demonstrated here to assist you in getting rid of the encountered issue, you can either opt for the most appropriate one or go for trying out all of the enlisted for more good results.

Clear the cache data of Safari Browser

Although there might be many other ways by which cache & cookies can occupy your iPhone’s storage. Still, the browser is considered the most significant source in this connection because of its excessive usage. The iPhone users usually access dozens of websites using Safari browser, and each time few cookies get stored in device cache memory.

So, you’d need to clear out this cached data of the Safari browser manually through your phone’s settings. For this:

  • Open the settings of your respective device (iPhone, iPad, or iPod).
  • Navigate to the Safari browser in the settings menu and tap on it.
  • In Safari browser’s settings, scroll down to locate & select the “Clear History and website data” option.
  • Then, you need to tap on the option “Clear history and data” to confirm the clearing process.

Clear the cache data of Chrome Browser

It is a fact that Safari is the most popular browser for iPhone users, but it won’t be wrong to say that Chrome is the second most frequently used browser in iPhone users’ community. So, you may be required to clear the cache data stored by the Chrome browser also. To do so:

  • Launch the Chrome browser on your iPhone.
  • Click on the three-dotted icon in the top right corner and select the Settings option.
  • In the Chrome Settings menu, scroll down and click on the option “Advanced.”
  • In advanced Chrome settings, navigate to the Privacy tab.
  • Now, select the option Clear browsing data.
  • Here, choose the specific time range in the displayed menu.
  • Checkmark the Cookies, Site Data, Cache images, and files and proceed on by clicking on the button Clear Browsing Data located at the bottom.

Clear cached data of Installed Apps

The one other considerable cause of affected iPhone performance is the cache data stored by apps installed on your iPhone storage. Because if we peep over this factor more closely, we can see that the apps we use on a frequent basis contribute significantly to occupying the device RAM due to the associated cache data.

Although some apps come with a built-in feature to clear the cookies & cache data, but this isn’t the case with every application you install. So, in adverse circumstances, there is no particular manual way to clear the apps’ stored cookies or cache, unfortunately.

Therefore, reinstallation of the apps is the only option you can opt for tackling the cache-oriented issue on your iPhone. Note that this reinstallation will wipe out all of the saved data, i.e., files, passwords, settings, etc., associated with the particular app, and you would be required to login to your accounts again upon reinstallation.

Here, the whole reinstallation method is explained step by step; you need to follow the stated process precisely.

  • At first, launch the settings in your iPhone, and here, select the “General” option by tapping on it.
  • In the General settings, locate the option “Storage & iCloud Usage” and select it.
  • In the storage & iCloud usage menu, scroll down and tap on the option “Manage Storage.”
  • Here you’d be able to see a list of all the apps with the memory information occupied by each app.
  • Now, identify the apps that are occupying more storage, select the particular apps and proceed on by choosing the Delete App option in each app individually. (You can practice out the same procedure for all apps that show more occupied memory)
  • Afterward, open the App Store on your device and reinstall all the apps you have deleted just recently.

We have also found the many users’ queries on how to clear Facebook cache on iPhone; basically, Facebook is one of those apps that comes with a built-in feature to clear space occupied by photos & videos cache data; therefore, you can use this built-in option more feasibly instead of going through the reinstallation process.
