Learn How to Clear Cache on Samsung Phones

Understanding Cache and Why It Builds Up on Samsung Phones

Cache is temporary data that apps and your phone's operating system store to help things run faster. When you open an app like Facebook, YouTube, or Gmail, your phone saves small pieces of information from that app. This cached data includes things like images you've viewed, login information, and parts of web pages. The next time you open that app, your phone uses this stored data instead of downloading everything again, which makes the app load quicker.

Over time, cache files accumulate on your Samsung phone. A single app might store hundreds of megabytes of cached data. If you have 50 apps installed, that's potentially several gigabytes of storage being used just for cache. This buildup happens gradually and many people don't notice it happening until their phone starts running slowly or storage becomes tight.

Cache serves an important purpose—it genuinely does make apps load faster. However, cached data can sometimes become corrupted or outdated. When this happens, an app might crash, display old information, or behave unpredictably. Clearing cache won't make your apps permanently faster, but it can fix problems caused by corrupted cache files and free up valuable storage space on your device.

The amount of cache varies greatly depending on how much you use your phone. Someone who watches videos daily might have 2-3 gigabytes of cached video data, while someone who uses their phone minimally might only have a few hundred megabytes. Understanding this helps explain why clearing cache produces different results for different people.

Practical Takeaway: Cache is useful temporary data that speeds up apps, but it accumulates over months and can cause problems when corrupted. Learning to clear it maintains your phone's performance and frees storage space.

Clearing Cache for Individual Apps on Samsung Devices

The most targeted way to clear cache is to remove it from specific apps rather than your entire phone. This approach lets you keep cached data from apps you use frequently while clearing cache from apps that cause problems. On Samsung phones running Android 9 and newer, the process is straightforward and takes about two minutes per app.

To clear cache for a single app, open your Settings app and navigate to "Apps" (this may appear as "Applications" on some Samsung models). Browse through the list and select the app you want to clear cache from. Once you've selected the app, tap "Storage" or "Storage and cache." You'll see two options: "Clear cache" and "Clear data." Tap only "Clear cache"—don't tap "Clear data" unless you want to log out of the app and reset its settings. After tapping "Clear cache," the process usually completes within seconds.

For apps that are causing specific problems, this method works particularly well. If YouTube keeps freezing, or Gmail won't load messages properly, clearing just that app's cache often fixes the issue without affecting anything else on your phone. You might need to log back into the app on your next use, but your saved data remains intact.

Some popular apps store particularly large cache files. Google Chrome, Instagram, and Spotify are known for accumulating 500 megabytes to 2 gigabytes of cache. If you notice your phone's storage is nearly full, clearing cache from these heavy hitters can reclaim substantial space. You can check how much cache an app is using by going to Settings > Apps > [App Name] > Storage—the cache size appears next to "Cache."

Practical Takeaway: Clearing cache for individual problem apps takes two minutes and fixes many common issues like freezing or slow loading without logging you out or deleting saved data.

Clearing All System Cache at Once on Samsung Phones

When you want to clear cache from your entire phone rather than individual apps, Samsung provides a system-wide option. This approach is faster than clearing app-by-app and can reclaim substantial storage in one action. The method differs slightly depending on which version of Android your Samsung phone runs, but the concept remains the same across models.

For Samsung phones running Android 11 and newer (which includes most recent Samsung Galaxy models), go to Settings, then select "Apps." At the top or bottom of the screen, you'll see a menu button (three vertical dots). Tap this and select "Show system apps." Find the app called "Device Care" or "Storage" and open it. Select "Storage" from the menu. You'll see an option to "Clean now" or "Optimize storage." This feature scans your phone and removes unnecessary cache files automatically. The process might take 30 seconds to two minutes depending on how much cache is stored.

For older Samsung phones running Android 10 or earlier, you can access cache clearing through Settings > Device Care > Storage > Optimize or Clean. This performs a similar function across all apps simultaneously. The phone will display how much space was freed after the process completes.

An alternative method that works on virtually all Samsung models involves clearing the partition that stores system cache. Restart your phone and hold the Volume Up button and Power button simultaneously until you see the Samsung logo. Keep holding until the recovery menu appears (this typically takes 5-10 seconds). Use the volume buttons to navigate to "Wipe cache partition" and press Power to select it. Your phone will clear the system cache partition and restart automatically. This method clears more technical cache files and usually takes 2-3 minutes total.

Practical Takeaway: System-wide cache clearing can remove gigabytes of temporary files in one action, making it useful when your phone feels sluggish or storage is critically low.

Clearing Browser Cache on Samsung's Default Browser

Browsers accumulate cache differently than regular apps because they store data for websites you visit. Samsung phones come with Samsung Internet (the default browser) which has its own cache management system separate from the app cache discussed previously. Clearing browser cache separately from app cache gives you more control over your data and can solve problems like websites displaying outdated information.

To clear cache in Samsung Internet, open the browser and tap the menu button (three horizontal lines at the bottom right). Navigate to "Settings" and then select "Privacy." You'll see an option for "Delete browsing data." Tap this, and a popup appears with several options: browsing history, cookies, cached images and files, and passwords. Check only the box next to "Cached images and files" if you only want to clear browser cache. If you want to clear everything, you can check multiple boxes. The checkmark next to "Cookies and site data" also removes saved login information for websites. Tap "Delete" at the bottom, and the process completes in a few seconds.

If you use Google Chrome on your Samsung phone instead of Samsung Internet, the process differs slightly. Open Chrome and tap the three vertical dots in the top right corner. Select "Settings," then "Privacy and security," then "Delete browsing data." Choose your time range (Last hour, Last 24 hours, Last 7 days, Last 4 weeks, or All time). Check "Cookies and site data" and "Cached images and files," then tap "Delete data."

Browser cache typically accounts for 200 megabytes to 1 gigabyte of storage, depending on how much you browse. Clearing it regularly prevents websites from loading incorrectly and removes old data that websites have collected about your browsing. Unlike app cache, you might notice a slight delay the first time you revisit frequently-used websites after clearing browser cache, as the browser needs to reload website files.

Practical Takeaway: Browsers store separate cache from apps; clearing browser cache solves website display issues and removes browsing data stored on your device.

Preventing Excessive Cache Buildup Going Forward

Once you've cleared cache from your Samsung phone, understanding how to prevent it from becoming problematic again will help maintain your device's performance long-term. Cache management doesn't require constant monitoring—a simple routine prevents buildup without requiring daily action.

Most Android experts recommend clearing cache monthly as a maintenance routine, though frequency depends on usage. If you watch hours of video daily, use social media constantly, or play graphically-intensive games, clearing cache every two weeks may prove beneficial. If you use your phone casually for email and messaging, monthly clearing is sufficient. Consider clearing cache whenever you notice your phone running slowly or when storage falls below 2 gigabytes.

Some Samsung phones include automatic cache management features. Go to Settings > Device Care > Storage and check if "Auto clean" or "Automatic optimization"
