Smartphones series Samsung Galaxy are famous for their quality and functionality, but over time, even the most powerful devices begin to work slower. The main reason for poor performance is that the internal memory is full of system junk, application caches, and forgotten files. When the storage is more than 90% full, the operating system Android experiences difficulties in creating temporary files necessary for apps to function correctly.
Users often notice that the phone begins to slow down, applications crash, and the camera takes longer to save pictures. These are direct signals that it’s time to do some spring cleaning in the digital space of your device. In this article, we will examine in detail effective and safe methods for freeing up space that will help restore your Galaxy former speed without losing important data.
Using the built-in maintenance tool
Samsung has equipped its devices with a useful utility that automatically analyzes the system status. This tool is located in the settings menu and allows you to delete temporary files that are no longer needed by the system with one touch. It is accessed through the section Settings → Device maintenance (or Device care in new versions of One UI).
By clicking on the "Optimize now" button, you will start the process scan that will check RAM usage, battery health and storage capacity. The system will automatically close background processes and offer to delete files that are taking up space. This is the safest method for novice users, since the algorithm does not touch personal photos or documents.
However, it is worth understanding that the built-in optimization removes only superficial garbage. Deep cleaning will require manual intervention in the settings of specific applications. This is especially true for social networks and instant messengers, which tend to accumulate gigabytes of data over several months of active use.
Run the built-in optimization once a week in the evening, when the phone is not actively used, so that the system can safely close background processes.
Clearing the application cache and data
Cache is temporary data that applications saved to speed up their work. For example, the browser stores copies of visited pages, and Instagram stores photo previews. Over time, the cache size can reach several gigabytes, although this data is not critical. Clearing the cache will not delete your logins or passwords, but will reset the display settings inside applications.
To delete the cache selectively, go to the menu Settings → Applications. From the list, select the app that takes up the most space (often YouTube, TikTok, or the Chrome browser). Inside the application card, find the item Storage and click the "Clear cache" button. Be careful not to confuse this button with the “Clear data” option, which will delete all information about your account in this application.
If you want to clear the cache of all applications at once, you can use the recovery mode. To do this, turn off the phone, then hold down the combination of buttons (depending on the model, usually this Volume up + Power) to enter Recovery Mode. In the menu that appears, select Wipe Cache Partition. This action is safe for your personal files, since it affects only the system temporary partition.
Why is the cache needed and can it be permanently deleted?
The cache speeds up the loading of frequently used items. If you remove it daily, apps will run a little slower when you first launch them, but you'll save space. It is optimal to do this once a month or when the memory is critically full.
⚠️ Attention: Clearing the “Data” section in the application settings will lead to a complete reset of the app. You will lose your chat history, saved drafts and settings within a specific service.
Managing downloads and files in the Download folder
Folder Download (Downloads) is the place where all files received from the Internet are accumulated: installation APK files, PDF documents, pictures from browsers and attachments from mail. Many users forget about this directory, allowing it to grow to enormous sizes. Checking this folder regularly is one of the most effective ways to quickly free up space.
Open the application My files (My Files), which is pre-installed on all Samsung smartphones. Go to the "Downloads" or "Documents" category. Sort files by size to see the heaviest items at a glance. Often there you can find old installation files for updates or forgotten videos that have already been watched.
- 🗑️ Delete application installation files (.apk), since after installing the app they are no longer needed.
- 📄 Check your documents folder for duplicate invoices or instructions.
- 🎵 Browse downloaded music and delete tracks that you no longer listen to.
- 🖼️ Filter images and delete bad screenshots or memes.
Don't forget to check the folder Bluetoothif you often receive files wirelessly. Heavy media files received from friends or colleagues may also accumulate there. Samsung's system file manager allows you to select groups of files and delete them en masse, which significantly saves time.
☑️ Monthly check of downloads
Storage analysis and removal of duplicates
Modern versions of the One UI shell provide detailed statistics on memory usage. In the Settings → Device maintenance → Memory section you will see a chart showing which file categories take up the most space. This helps you understand where exactly the free space is going: on photos, applications or system files.
Particular attention should be paid to media files. Often, the gallery stores dozens of identical photos taken in burst mode, or duplicate videos uploaded several times. The application Gallery has a search function for similar images, which offers you to select the best photo from a series and delete the rest. There are also third-party applications for finding duplicates, but Samsung's built-in tools work quite effectively and safely.
If you use cloud services such as Google Photos or Yandex.Disk, use the "Free up space" function. It finds on the device those pictures and videos that have already been successfully uploaded to the cloud, and deletes their local copy. This allows you to store your entire media library on the Internet without occupying the phone’s internal memory.
Cloud storage is the best way to unload memory, but requires a stable Internet connection to view photos in high quality.
Cleaning messengers: WhatsApp, Telegram, Viber
Messengers are the main "eaters" of memory on a modern smartphone. Automatic saving of all received photos and videos quickly fills gigabytes. Fortunately, popular applications have built-in storage management tools that allow you to remove junk without losing important correspondence.
Go to Telegram go to Settings → Data and memory → Memory usage. Here you can clear the cache and set up automatic deletion of media files that have not been opened for a certain time (for example, a week or a month). This is a very convenient function, since if necessary, you can always re-upload a photo from the chat.
In WhatsApp the situation is a little different. Go to Settings → Data and storage → Storage management. The application will show a list of chats sorted by the amount of space they occupy. You can go into a specific dialogue and delete large videos or sent files, leaving the text chat history intact.
| Messenger | Where to look for settings | Deletion security cache | Automatic cleaning |
|---|---|---|---|
| Telegram | Settings → Data and memory | Completely safe | Yes (by time) |
| Settings → Data and storage | Safe for media | No (manual only) | |
| Viber | More → Settings → Storage | Safe for cache | Limited |
| Discord | Account settings → Data | Reinstallation required | No |
⚠️ Attention: The messenger interface is updated frequently. If you do not find the specified menu items, use the search inside the application settings for the word “Memory” or “Storage”.
Transfer data to a memory card and the cloud
If your internal memory Samsung Galaxy physically limited (for example, 64 GB or 128 GB), the most reasonable solution would be to transfer heavy files to external media. Many models support microSD memory cards, which can hold up to 1 TB of data. This is an ideal place to store archives of photos, videos and music.
To move files, use a file manager. Select the desired folders (for example, DCIM/Camera), click the "Move" menu and select the SD memory card. After transferring, configure the camera so that new photos are immediately saved to the card. This is done in the application settings Camera → Gear icon → Save location → SD memory card.
For those who do not want to carry extra cards with them, cloud services are suitable. Google Drive, Dropbox or the proprietary Samsung Cloud allow you to set up automatic synchronization.
Is it possible to transfer applications to a memory card?
In modern versions of Android, this function is limited. You can transfer only part of the data of some applications, but system apps and most heavy games should remain in the internal memory for performance.
Deleting unused applications and widgets
Often we install applications “one time” and forget about them. They take up space not only with their installation file, but also with data that continues to accumulate in the background. Regular audit of installed software is an important part of maintaining a clean system.
Go to the list of all applications and sort them by frequency of use or installation date. If you have not opened the app for the last 3 months, feel free to delete it. Don't be afraid to delete something important: any application can be downloaded again from Google Play Store or Galaxy Store.
- 📱 Delete pre-installed games that you have never played.
- 🛒 Demolish store applications if you do not place orders every day.
- 📰 Get rid of news aggregators if you read news in a browser.
- 🎁 Remove trial versions of services that have expired.
Also check your desktop for widgets. Some of them, such as weather stations or news feeds, constantly update data and store a cache. Removing unnecessary widgets will not only free up some memory, but will also save battery power.
Before deleting an application, go to its settings and check if there are any important saved data or drafts that need to be exported.
Is it possible to delete Samsung system applications?
Delete system applications without root access is impossible using standard means. Trying to do this through a computer and ADB may result in the phone becoming unstable or voiding the warranty. It is better to simply disable them in the settings, if such an option is available.
Why does the memory fill up immediately after cleaning?
This is normal system behavior. Applications immediately begin to create new temporary files (cache) for their work. The phone can also download system updates or sync photos in the background. If the memory fills up critically quickly (within a couple of hours), perhaps some application is not working correctly.
Does full memory affect Internet speed?
There is no direct effect on the connection speed, but clogged memory slows down the browser and applications. Pages may take longer to load not because of the network, but because the phone has nowhere to write temporary data to display content.
Do you need to buy applications to clear memory?
In most cases, no. The built-in Samsung and Android tools are quite enough for proper cleaning. Third-party “cleaners” are often themselves a source of advertising and unnecessary garbage, and their functions duplicate system capabilities.
