Does clearing cache make phone faster?

  • If you clear the cache on your Android phone periodically, you could help eliminate performance issues on the device. 
  • Your Android phone's cache comprises stores of small bits of information that your apps and web browser use to speed up performance.
  • But cached files can become corrupted or overloaded and cause performance issues. 
  • Cache needn't be constantly cleared, but a periodic clean out can be helpful.

Your apps and web browser store bits of information to speed up your experience using them.

Over time, your phone may collect a lot of files you don't really need. You can clear out the files to free up a little storage space on your device. Clearing cache can also help with website behavior issues.

Clearing browser cache and app cache from an Android phone is a quick and easy process.

Here's a short guide on how to do both.

6. Tap the Clear data button to clear cache.

Clear cache from third-party apps

App cache is similar to browser cache. It's small bits of information stored to speed up your experience using an app. However, there may be times when an app suddenly closes or stops responding all together. Problems with cached data could be the culprit.

Clearing cache is a quick and easy way to free up space and (hopefully) fix a misbehaving app. Clearing app cache will not delete app data like account information.

Here's how to clear app cache:

1. Go to the Settings menu on your device. 

2. Tap Storage.

5. Tap OK when a dialog box appears asking if you're sure you want to clear all app cache.

Clearing app cache will not delete app data like account information. App data, like account information, can be deleted from the same menu - proceed with caution if you decide to do so. 

Note: Phones without SD card storage will not be given a choice to select between internal storage or SD card as shown in the above screenshots.

How often you should clear cache

You may find it helpful to clear cache periodically, but a regular cache clearing schedule isn't required. If you find you're routinely clearing cache to free up space, you may consider removing unused apps or archiving stored video and photos in the cloud. Installing a high volume microSD card is another option to address phone storage needs.

Your iPhone holds two major data caches: One for browsers like Safari and Chrome, and another for your apps. Clearing these caches can free up space on your iPhone, improving speed and performance by removing unnecessary app data.

Here's how to clear both caches on your iPhone.

What is a cache?

A cache is hardware or software that collects temporary data in order to help websites, browsers, and apps load faster on your devices that access the internet. 

In many cases caches help devices run faster, using saved data to access websites you frequent rather than having to redownload everything every time you visit a website or open an app.

After visiting a lot of websites or using various apps, your cache can get cluttered and take up a lot of storage space. To help your device run smoothly, it's a good idea to clear your cache every so often.

How to clear the cache, history, and cookies in Safari

When you clear your iPhone's Safari cache, all of the files, images, passwords, and scripts from websites you've visited recently will be wiped.

How to clear your iPhone's app cache

To clear the cache for your iPhone apps, you'll need to offload them. Offloading an app will free upstorage space the app uses while still keeping its documents and data. When you reinstall the app, your data will be recovered.

1. Open the Settings app and tap General, then select iPhone Storage.

2. Wait for the list of all your apps to load. Once it's generated the list, select the app you want to clear and tap Offload App. You'll also be able to delete the app here.

When you offload an app, you can start right where you left off once the app is reinstalled. Abigail Abesamis Demarest/Insider

When you open the list of all your apps, you might see a menu called Offload Unused Apps. Tapping Enable here will let your iPhone automatically offload apps that you haven't used in a while.

What is the difference between clearing cache and offloading?

Clearing your cache removes stored data that helps websites and apps open faster, while offloading temporarily uninstalls an app without deleting any of the documents and data associated with that app. 

Both methods can help speed up iPhones that are slowed down by low storage.

How can I clear my cache from another browser on my iPhone?

If Google Chrome is your go-to browser, clear the cache by following these steps:

1. Open the Google Chrome app. Tap the More icon.

2. Tap Clear Browsing Data.

3. Select a time range. Options range from the last hour to all time.

4. Ensure Cookies, Site Data and Cached Images and Files are checked, then tap Clear Browsing Data.

When you’re ready, tap Clear Browsing Data. Abigail Abesamis Demarest/Insider

Are cookies and cache the same?

They are not. Cookies are small files that store information about your online activity. 

While most cookies are functional and used to track what sites you're logged in to and your website preferences for a particular site, there are also third-party cookies that track your activity across different websites. This includes search history and things you've clicked on.
