Over time, any smartphone, even the most productive, begins to slow down. The main culprit behind this process is the internal storage becoming full and poor management of random access memory (RAM). Users often wonder if it is possible to manually intervene in system processes to speed up the device. Changing memory settings on Android is not a myth, but a very real process, accessible to both ordinary users and advanced enthusiasts.
Modern versions of the operating system Android have complex resource management algorithms that are hidden from the user’s eyes. However, there are legal optimization techniques that can free up space and improve interface responsiveness. It is important to understand the difference between permanent memory (ROM), where your photos and applications are stored, and RAM (RAM), which is responsible for the performance of running apps. Incorrect interference with the operation of the second one can lead to system instability.
In this article we will analyze in detail the available tools, from standard settings menus to hidden features for developers. You'll learn how to safely migrate data, clean up system junk, and set background process limits. Remember that each smartphone model, be it Xiaomi, Samsung or Pixel, may have its own menu layout features.
Managing internal memory and data storage
The first step in optimizing your device is to analyze what exactly your storage is filled with. The standard settings menu provides basic tools for managing files. To access this data, you need to go to section Settings → Storage (or Memory). Here the system visualizes the distribution of space between applications, images, videos and system files.
Many users ignore the “Cached Data” section, which can take up gigabytes of space. Cache are temporary files that make applications load faster, but over time they become redundant. Clearing the cache does not delete your personal data, logins or passwords, but it may temporarily slow down the first launch of some apps after the procedure. This is a safe way to instantly free up space.
For deep cleaning, you should use the built-in Free up Space tools. Algorithms Android offer to delete old screenshots, duplicate files and applications that you have not used for more than a month. In some shells, for example MIUI or One UI, these functions are included in separate optimizer applications with expanded functionality.
Care should be taken when deleting files from system application folders. Although modern versions of the OS protect critical data, manual deletion through a file manager can lead to malfunctions of apps that use these files to save progress or settings.
⚠️ Attention: Do not delete files with the .obb extension or folders with the names of installed games manually through a file manager if you do not plan to delete the application itself. This will require a complete restart of the game.
Use the "Data Compression" function in instant messengers (for example, Telegram or WhatsApp) to automatically reduce the size of downloaded photos and videos, saving gigabytes of memory in the long run.
Transferring applications to an SD memory card
Owners of smartphones with small capacity built-in memory often resort to installing microSD cards. However, simply inserting a card is not enough - you need to properly configure the system to work with it. Starting from version Android 6.0, the "Adoptable Storage" function appeared, allowing you to use the card as an extension of the internal memory.
To activate this mode, go to Settings → Storage → SD card. In the card menu, select the "Use as internal memory" option. The system will prompt you to format the media. Important: all data on the card will be deleted, so first copy important files to your computer. After formatting, the card is encrypted and works only with that specific device.
Not all applications support transferring to external media. Software developers can disable this feature in the application manifest if they feel that the SD card is not fast enough to run their product smoothly. In such cases, the "Transfer" button will be inactive.
Why some applications cannot be transferred?
Developers limit transfer to an SD card due to the difference in read/write speeds. Internal memory (UFS) is significantly faster than most microSD cards, and transferring heavy games or system utilities can cause freezes.
If the standard method does not work, you can try a forced transfer through the developer menu, but this requires having root access or using special utilities on the computer. Without superuser rights, the capabilities are limited to the standard shell functionality.
☑️ Preparing the memory card for use
RAM settings through the developer menu
For finer tuning To improve system performance, there is a hidden menu "For Developers". It allows you to control the behavior of the operating system regarding background processes and animations. To activate this section, you need to click on the build number 7 times in the menu About phone.
In the menu that opens, find the "Applications" section. The "Background process limit" parameter is located here. By default, the system itself decides how many applications to keep in memory. You can manually limit this number by selecting the "No more than 2 processes" or "No background processes" option. This will force the system to more aggressively unload applications from RAM, freeing up resources for the active task.
You can also find animation settings in this section. Changing the animation scale of windows, transitions and animator duration to 0.5x will visually speed up the interface. The phone will respond to taps faster, although the actual processor performance will not change. This is an effective trick for older devices.
| Settings | Default value | Recommended value | Effect |
|---|---|---|---|
| Window animation | 1x | 0.5x | Speed up opening applications |
| Animation of transitions | 1x | 0.5x | Fast switching between screens |
| Animator duration | 1x | 0.5x | Reducing response time |
| Background processes | Standard | No more than 3 | Freeing up RAM |
Be careful when setting the "No background processes" limit. This may disrupt the work of instant messengers, which will stop receiving notifications in real time, since the system will instantly kill their process when minimized.
Using the RAM Plus and virtual memory function
Modern manufacturers, such as Samsung, Xiaomi and Realme, are introducing virtual memory technology, often called RAM Plus or "Memory expansion". This function uses part of the free space on the internal drive to create a page file that simulates RAM.
You can find this setting in the section Settings → Device maintenance → Memory (the path may vary depending on the brand). The user is asked to select the amount of virtual memory: 2 GB, 4 GB or more, depending on the model. The system reserves this space and it becomes unavailable for storing files.
The effectiveness of this technology depends on the speed of your drive. If your phone uses fast memory UFS 3.1, the performance increase when multitasking may be noticeable. However, on budget devices with slow memory eMMC enabling this function sometimes leads to the opposite effect - slowdowns due to the low speed of data exchange with the swap file.
⚠️ Attention: Enabling virtual memory reduces the available storage space for your files. Make sure you have enough free space before activating this feature.
It has been experimentally proven that on devices with 8 GB or more physical RAM, enabling RAM Plus often does not provide a tangible benefit, since the system lacks real resources. This feature is most useful for budget smartphones with 4 GB of RAM.
Virtual memory is a trade-off: you sacrifice disk space for the ability to keep more apps open, but performance may be slower on slower drives.
Clearing the partition cache and system reset
When software cleaning methods do not help, you can resort to more radical measures through recovery mode (Recovery Mode). This method allows you to clear the cache of the entire system without deleting user data (photos, contacts, applications). This is useful after major firmware updates, when the system may be unstable due to conflicts with old temporary files.
To enter Recovery mode, you usually need to turn off the phone and hold down a combination of buttons, for example, Volume Up + Power. The control menu is carried out using the volume buttons, and the selection is confirmed with the power button. You need to find the item Wipe Cache Partition and confirm the action.
Do not confuse this operation with Wipe Data/Factory Reset. The last command will completely delete all information from the phone, returning it to its factory state. Wiping the cache partition is safe and only takes a few minutes, after which the device will reboot.
If the phone suffers from critical errors that cannot be fixed, a full reset is the only working option. Before doing this, be sure to create a backup copy of your data in the cloud or on your computer, since it will be impossible to recover deleted files without a backup.
What to do if the Recovery menu does not open?
On some new models (especially Samsung), to enter Recovery you need to connect the phone with a cable to the computer before pressing the buttons. Without a connection to a PC, the key combination may not work.
Third-party applications and myths about optimization
In the store Google Play there are thousands of applications that promise to “speed up your phone in one click” or “increase RAM.” Most of them are useless or even harmful. The principle of their operation often comes down to forcibly closing processes, which the system Android immediately starts again, consuming even more battery power and processor resources.
The Android operating system is designed to make the most efficient use of available RAM. Empty RAM is wasted memory. The system deliberately keeps frequently used applications in memory so that they open instantly. Constant artificial memory cleaning disrupts this balance and leads to more frequent loading of data from the disk, which slows down work.
The only third-party utilities that can be useful are advanced file managers for analyzing used space (for example, Files by Google or Solid Explorer) and specialized tools for freezing applications (require complex settings). Regular "cleaners" most often just show annoying ads.
- 🚫 Avoid applications that promise to "cool the processor" by cleaning memory - this is technically impossible programmatically.
- ✅ Use built-in cleaning tools, they have a higher priority in the system and work safer.
- ⚠️ Do not install several antiviruses and optimizers at the same time - they will conflict with each other.
⚠️ Attention: Settings interfaces may differ depending on the Android version and the manufacturer's shell. If you do not find the described menu item, use the search in the phone settings.
Frequently asked questions (FAQ)
Is it possible to increase the physical RAM on the phone?
No, the amount of physical RAM (RAM) is determined by hardware during the production of the device and is soldered into the board. It is impossible to change it programmatically. Functions like RAM Plus only create the illusion of expansion due to slow internal memory.
Why does the phone start to work slower after clearing the memory?
This is normal behavior of the Android system. After a cleanup, the system requires time and CPU resources to re-index files, load necessary services, and fill the cache. Typically, performance is restored after 10-15 minutes of active use.
Is it safe to disable animation in the developer settings?
Yes, it is absolutely safe. Disabling or reducing the animation scale does not affect the stability of the system, but only changes the visual perception of the speed of the interface. You can always return the default values (1x) at any time.
How to transfer WhatsApp to a memory card?
The WhatsApp application itself can often not be transferred to a memory card due to developer restrictions. However, in the settings of the messenger itself (Settings → Chats → Chat backup), you can change the storage location of media files and backups to the SD card, if this option is supported by your version of the application.
Deleting which folders will free up the most space?
The largest volume is usually occupied by folders with caches of social networks and instant messengers (for example Android/media/com.whatsapp or Telegram cache). Also, downloaded offline maps in navigators and the cache of streaming services like YouTube or Spotify can take up a lot of space.
