Random access memory (RAM) is a key component of a smartphone, on which the speed of applications and multitasking depend. When it is not enough, Android begins to slow down, applications close spontaneously, and games freeze. Many users are looking for ways increase RAM on Android, but not all methods are equally effective.

In this article we will look at real ways to optimize memory - from basic settings to advanced tricks with swapfiles and virtual memory. Weโ€™ll also debunk the myths about โ€œmagicโ€ applications that supposedly add gigabytes of RAM in 5 minutes.

It is important to understand: physically increasing the amount of RAM on a smartphone can only be done by replacing the microcircuit (which requires soldering equipment and skills), but optimizing its use is a doable task.. Let's start with simple steps that do not require root access.

1. Clearing the cache and background processes

The first thing to do is to free up memory that is already occupied. Even if you Samsung Galaxy S23 with 12 GB of RAM, over time the system and applications accumulate unnecessary data.

How it works: Android stores temporary files (cache) for quick access to applications. But if the cache grows to gigabytes, it begins to โ€œeat upโ€ the RAM. Cleaning will not delete your data, but will free up resources.

  • ๐Ÿ“ฑ Manually clearing the cache: Go to Settings โ†’ Applications โ†’ Select application โ†’ Storage โ†’ Clear cache. Pay special attention to instant messengers (Telegram, WhatsApp) and social networks.
  • ๐Ÿงน Auto cleaning: Enable the function in Settings โ†’ Device maintenance โ†’ Optimization (on Xiaomi โ€” Security โ†’ Cleaning).
  • โš™๏ธ Limit background processes: B Settings โ†’ For developers โ†’ Process limit select "Maximum 2 processes in the background" (developer mode must be activated).
โš ๏ธ Attention: Clearing the cache Google Play Services or Android System WebView can lead to temporary disruptions in Google services. After cleaning, restart your smartphone.
๐Ÿ“Š How often do you clear the cache on your smartphone?
Once a week
Once a month
Only when it slows down
Never

2. Disabling unnecessary applications and services

Many pre-installed applications (bloatware) work in the background, consuming RAM. For example, on Samsung this Bixby, Samsung Free, and on Xiaomi โ€” Mi Video, Mi Music.

How to reduce the load:

  • ๐Ÿšซ Disable: Go to Settings โ†’ Applications โ†’ Select unnecessary โ†’ Disable. This will remove it from the active list, but will not delete the files.
  • โ„๏ธ Freeze: Applications like Greenify (requires root) or Brevent (without root, but with ADB) can "put to sleep" background processes.
  • ๐Ÿ”„ Alternative firmware: Installation LineageOS or Pixel Experience will remove the bloatware, but will require unlocking bootloader.
Brand Typical "bloatware" Is it possible to remove without root?
Samsung Bixby, Samsung Pay, AR Emoji You can disable it, but you canโ€™t delete it
Xiaomi Mi Browser, Mi Music, Cleaner Partially (via ADB)
Huawei Huawei AppGallery, HiCare, Petal Search Disable only
๐Ÿ’ก

Before disabling system applications, check them in AppBrain - some are related to critical functions (for example, Android Auto on some devices it is responsible for Bluetooth).

3. Using an SD card as virtual RAM (swap)

One of the controversial, but sometimes effective methods is creating a swapfile on an SD card. This allows you to use part of the external memory as additional RAM. Cons: SD cards are slower than RAM, and this can slow down the system when intensive. load.

How to configure (required root):

  1. Install Terminal Emulator or connect via ADB.
  2. Enter commands:
    su
    

    mkdir /sdcard/swap

    dd if=/dev/zero of=/sdcard/swap/swapfile bs=1M count=1024

    mkswap /sdcard/swap/swapfile

    swapon /sdcard/swap/swapfile

    Here count=1024 is the swap size in megabytes (it is not recommended to set more than 2 GB).

  3. To enable swap automatically, add a line /sdcard/swap/swapfile none swap sw 0 0 to the file /etc/fstab.
โš ๏ธ Attention: Frequent use of swap on cheap SD cards (lower class UHS-I) can lead to their rapid wear. For tests, use cards marked A1 or A2.
What happens if you interrupt the creation of a swap file?

If the process dd abort, the file will be damaged. Delete it through the file manager with root access (Root Explorer) and repeat the procedure. Incorrect swap can cause reboot cycles!

4. Optimizing Android to save RAM

Some system settings directly affect consumption. memory. Here's what you can change:

  • ๐ŸŽจ Animation: Disable or reduce animation in Settings โ†’ For developers โ†’ Scale animations (select "No animation"). This will speed up the interface and reduce the load.
  • ๐Ÿ”„ Auto-update: Disable automatic application updates in Google Play (Settings โ†’ Network settings โ†’ Auto-update applications โ†’ Never).
  • ๐Ÿ“ด Light theme: Use lightweight launchers (Nova Launcher, Lawnchair) and design themes without heavy widgets.

For devices with Android 10+ a function is available "Lite mode" (Settings โ†’ Accessibility โ†’ Light modeIt disables the background activity of unnecessary services, but may limit functionality (for example, it will remove some). animations and widgets).

Disable interface animation|Clear messenger cache|Remove widgets from the home screen|Disable auto-synchronization of accounts|Use light alternatives applications (for example Facebook Lite instead of Facebook)-->

5. Applications to โ€œincreaseโ€ RAM: myths and reality

In Google Play hundreds of applications promising to โ€œincrease RAM by 2 timesโ€ or โ€œfree up 4 GB memory." 99% of them are dummies.which simply clear the cache (which you can do manually) or show false notifications.

Examples of useless applications:

  • ๐Ÿšซ RAM Booster, Memory Cleaner - clear the cache, but do not increase physical memory.
  • ๐Ÿšซ Game Booster โ€” close background processes, but after exiting the game everything returns.
  • ๐Ÿšซ Virtual RAM Expander โ€” creates swap, but is unstable without root.

The only useful utilities are Greenify (for freezing background processes) and SD Maid (for deep cleaning of the system). But they will not add physical memory to you.

โš ๏ธ Attention: Some RAM โ€œboostersโ€ contain advertising modules that themselves consume memory and battery. Before installation, check the reviews and permissions of the application.

6. Root methods: risks and opportunities. data-i="148">With root access, additional ways to manage memory open up, but this

Root access opens up additional ways to manage memory, but this risky: loss of warranty, the ability to โ€œbrickโ€ the device, security vulnerabilities.

What can be done with root:

  • ๐Ÿ”ง Changing minfree: File /sys/module/lowmemorykiller/parameters/minfree Determines when Android starts killing processes. Editing it allows you to more precisely control memory allocation.
  • ๐Ÿ—‘๏ธ Removing system applications: Using Titanium Backup or System App Remover you can completely remove the bloatware.
  • ๐Ÿ”„ Kernel with zRAM support: Some custom kernels (for example, FrancoKernel) optimize memory use by compressing data in RAM.

Editing example minfree (requires root and a file manager like Root Explorer):

echo "18432,23040,27648,32256,36864,41472" > /sys/module/lowmemorykiller/parameters/minfree

Values correspond to free memory thresholds (in 4 KB pages) for different process priority levels.

๐Ÿ’ก

Root methods give maximum control over RAM, but incorrect actions can lead to a "bootloop" (cyclic reboot). Always do backup NANDroid before experiments!

7. Alternative solutions: when nothing helps

If you've tried all the methods and still don't have enough RAM, consider the following options:

  • ๐Ÿ“ฑ Firmware update: Manufacturers sometimes optimize memory usage in new versions of Android. Check Settings โ†’ Software update.
  • ๐Ÿ”„ Reset to factory settings: A cardinal method that will delete all data, but return the system to its original state. Make a backup first!
  • ๐Ÿ’ฐ Upgrade devices: If your smartphone is older than 3-4 years (for example, Redmi Note 5 with 3 GB of RAM), it may be time to consider buying a new device with 6-8 GB of memory.

For gamers: some games (for example, Genshin Impact or Call of Duty: Mobile) require at least 4 GB of RAM. If your device doesn't work, try lowering the graphic settings in the game menu or use cloud gaming (Xbox Cloud Gaming, GeForce NOW).

โš ๏ธ Attention: On some devices (for example, Realme or Oppo), the "dynamic RAM expansion" function (RAM Expansion) uses part of the internal memory as virtual RAM. This option is enabled in Settings โ†’ Advanced โ†’ RAM expansion, but its effectiveness is controversial - tests show a performance increase of only 5-10%.

FAQ: Frequently asked questions about increasing RAM by Android

Is it possible to physically add RAM to a smartphone, like in a PC?

No. Unlike computers, where RAM is installed in slots, in smartphones the RAM chip is soldered into the motherboard. The only way to physically increase the memory is to replace the entire board, which is not economically feasible.

Is it true that applications like RAM Expander work?

Partially. They create a swapfile on the SD card or in the internal memory, but this is not real RAM, but only a buffer for temporary data. The effect is minimal, and on slow cards it can even worsen. performance.

Why does the RAM fill up again after clearing it?

Android is designed to use all available memory. Free RAM is inefficiently used RAM. The system caches frequently used data to speed up the work. If after cleaning the memory quickly fills up, this is how it should be.

How. check how much RAM is being used?

Go to Settings โ†’ Device maintenance โ†’ Memory (to Samsung) or use applications like CPU-Z ("Memory" section). Pay attention to the "Available" column - this is really free memory.

Is it harmful to constantly clear RAM?

Yes. Frequent forced cleaning forces the system to reload data into memory, which increases the load on the processor and reduces battery life. Clear RAM only if serious problems are noticeable. lag.
