Many users are faced with the fact that their Samsung Galaxy starts to work slower over time, applications take a long time to open, and the system periodically freezes. The main cause of such problems is often a lack of free resources, in particular, full storage and overloaded random access memory (RAM). Understanding how to properly distribute these resources is the key to long and stable operation of the device.
Modern brand smartphones use a shell One UIthat offers advanced tools for monitoring and cleaning the system, but standard methods are not always enough for deep optimization. In this article, we will analyze in detail the mechanisms of memory, learn to distinguish temporary files from system caches, and consider proven ways to free up space without losing important data.
Effective resource management is not just deleting photos, but an integrated approach to setting up a gadget. You'll learn how to use hidden developer features, properly configure startup, and understand which processes are really consuming energy and CPU resources right now.
Differences between RAM and internal memory
The first step to optimization is a clear understanding of the data storage architecture. Random Access Memory (RAM) is high-speed storage that is used by the system for temporary placement data from running applications. The more free RAM, the faster the processor can switch between tasks and the smoother the interface works.
In contrast, internal memory (ROM or User Storage) is used for permanent storage of the operating system, installed apps, photos, videos and documents. Filling out this section critically affects the speed of writing new data and can lead to errors in the system.
⚠️ Attention: Do not confuse clearing application caches with deleting their data. Clearing the cache is safe and frees up space, while deleting data will reset the app to factory settings, destroying logins and progress.
Modern models Samsungsuch as the series Galaxy S or Ause technology LPDDR5 for RAM, which provides high data exchange speed. However, even the fastest chips will not be able to work efficiently if the system partition is full of junk files.
To view the current state of resources, go to Settings → Device maintenance → Memory. Here you will see detailed statistics on the use of both types of memory in real time.
Analysis of storage capacity
Before taking radical measures to delete files, it is necessary to conduct a high-quality diagnosis. The system Android provides built-in tools that visualize this space. This allows you to instantly determine which categories of files occupy the leading positions.
Most often, the main “eaters” of space are multimedia files from instant messengers and the cache of streaming services. Users often forget that watched videos in YouTube or TikTok, as well as music listened to online are saved in the temporary storage of the application.
For a detailed analysis, use the built-in file manager My Files (My files). Go to the section Storage analysis, where the system will offer to delete duplicates, large files and rarely used applications.
| Data category | Influence type | Recommendation |
|---|---|---|
| Photo and Video | High ROM | Transfer to the cloud or PC |
| Application cache | Slowdown | Regular cleaning |
| Downloads | Garbage accumulation | Weekly check |
| Offline maps | Taking up space | Removing unnecessary regions |
Pay attention to the folder DCIM, where unsuccessful duplicate pictures and screenshots taken a month ago often accumulate. Deleting them is the fastest way to get a few gigabytes of free space.
Use the Compressed Images feature in Google Photos or Samsung Gallery to reduce the weight of files without any visible loss of quality, freeing up to 50% of space in the gallery.
Clearing cache and temporary files
Caching data is necessary to speed up the loading of frequently visited pages and running applications, but over time the cache size can grow to inadequate values. Some social networks are capable of accumulating gigabytes of temporary data in just a couple of weeks of active use.
To manually clear a specific application, go to Settings → Applications, select the desired service (for example, Instagram or Telegram) and go to the Storagesection. There is a button here Clear cachethat will delete temporary files without affecting your correspondence or account settings.
There is also a global clearing method via the recovery menu (Recovery Mode), however it requires rebooting the device and performing certain actions with physical buttons. This method is recommended only for experienced users who understand the risks of interrupting the process.
What is Dalvik Cache?
Dalvik Cache is an optimized cache for all applications on the device. Cleaning it in Recovery Mode can speed up the system after updating the firmware, but the first launch after that will take longer, since the system will recompile application code.
You can automate the process using the built-in optimizer. Just go to Settings → Device maintenance and press the button Optimize. The system will automatically close background processes and delete unnecessary temporary files.
Manage RAM and background processes
Manage RAM on Samsung has its own characteristics thanks to the aggressive energy saving policy of the shell One UI. The system strives to unload applications from memory as quickly as possible to save battery power, which sometimes leads to reloading tabs in the browser or losing the state of games.
To change priorities, open the menu of running applications (swipe up and hold) and click on the application icon at the top. Here you can select an option Allow background workthat will prohibit the system from unloading this application from RAM.
- 🚀 Use the Game Booster game mode to reserve maximum resources for the game process.
- 🛑 Close applications that you do not use, especially heavy navigators and video editors.
- ⚙️ Disable window animation in the developer menu to visually speed up the response of the interface.
It is also worth paying attention to the function RAM Plus, which is available on many modern models. It allows you to reserve part of the internal memory for virtual RAM. This is useful when running heavy games, but may slightly reduce the overall read/write speed of the drive.
☑️ Optimizing RAM
Use built-in optimization tools
The company Samsung has implemented a powerful set of tools combined into application Device Care (Device Maintenance). This module constantly monitors the status of the smartphone and offers solutions to resolve problems.
In the section Memory you can see a graph of RAM usage over the last 24 hours or 7 days. This helps identify "hungry" applications that consume resources even in the background when you are not using them.
Function Adaptive Battery is closely related to memory management. It learns your usage habits and limits applications you rarely use, thereby conserving resources for essential tasks.
⚠️ Note: The Device Maintenance menu interface may vary depending on the version. One UI and the model of your smartphone. If you do not find the described option, use the search in the settings.
Regular use of the built-in optimizer (once a week is enough) helps keep the system in good shape without the need to install third-party software, which is often itself a source of advertising and load.
Samsung’s built-in tools are more effective than third-party “cleaners”, since they have deep access to system processes and not conflict with shell protection.
Working with external drives and the cloud
If the built-in storage is absolutely not enough, consider expanding via a memory card microSD. Although modern flagships do not have this slot, many models of the mid-range and budget segments support cards up to 1 TB. Galaxy A And M Support cards up to 1 TB.
After installing the card, you can transfer media files, documents and even some applications to it (if the developer has allowed this in the application manifest). To transfer photos and videos to Gallery select files, press the menu and select Move, specifying the memory card as the destination location.
An alternative is cloud storage. Services like Google One, OneDrive (integrated into the system) or Yandex.Disk allow you to set up automatic photo uploading. After successful synchronization, the originals can be deleted from the device, leaving only the thumbnails.
Using cloud technologies requires a stable Internet connection, but frees up the physical memory of the device, which directly affects the performance of the system and the speed of the camera.
Additional methods and expert advice
For advanced users, it is possible to disable system applications that are not used but consume resources. This is done through the menu Settings → Applications, but requires caution so as not to disrupt the operation of critical services.
It is also worth checking the folder Downloads (Downloads) regularly. Browsers and instant messengers often store APK installation files, PDF documents and images there that are no longer needed. Deleting the contents of this folder is a safe way to quickly free up space.
- 📂 Check the folder WhatsApp/Media/.Statuses to delete viewed statuses.
- 🗑️ Empty the trash in the Gallery and in the My Files application, since deleted files are stored there 30 days.
- 📱 Delete old chat backups if they are taking up space in local memory.
Remember that completely rebooting the device every few days helps clear system logs and reset frozen processes, which has a positive effect on memory management.
Is it safe to use cleaner applications from Google Play?
Most third-party cleaners (Clean Master and analogues) work aggressively, forcibly closing processes that the system immediately starts again. This puts extra stress on the processor and battery. The built-in tools Samsung are quite enough to keep the system clean.
Why does the memory fill up immediately after cleaning?
This is normal system behavior. Applications create new caches for faster operation, and the system generates logs. If the space disappears instantly in gigabytes, check whether large files are being downloaded in the background or games are being updated.
Does filling up the memory affect battery life?
Yes, indirectly. When the storage is almost completely full (more than 90%), the system has a harder time finding free blocks to write temporary data, which increases the load on the memory controller and processor, leading to faster drainage.
How to transfer applications to an SD card on Samsung?
Go to Settings → Applications, select the application. If the button Change is active, you can move it to the map. If there is no button or it is inactive, the developer has prohibited the transfer of this application.
What to do if the phone says "Not enough memory" when shooting a video?
Free up at least 1-2 GB of space. Video, especially 4K, requires a large buffer to record the data stream. Also try lowering the recording quality in the camera settings from 4K to Full HD.
