Android is an operating system that constantly balances between performance and energy efficiency. One of the key mechanisms for this balance is background process limithidden in the developer menu. Many users are not even aware of its existence, although it directly affects how quickly applications switch, how much memory the system consumes, and how long the battery charge lasts.

This setting determines how many applications can simultaneously run in the background without being forcefully closed by the system. By default, Android itself adjusts this limit depending on the device model, OS version and available resources. However, in developer mode (Developer Options) it can be changed manually - and this is where the questions begin. Is it worth doing? Which values ​​are optimal for weak smartphones, and which for flagships? And most importantly: what are the risks of incorrect settings?

Today we will figure out how this mechanism works, what values to choose for different usage scenarios, and why arbitrarily increasing the limit can lead to the opposite effect slowdown and rapid battery drain.

What are background processes in Android and why they are limited

Background processes are tasks that are performed by applications, even when you do not see them on the screen. For example:

  • 📱 Data synchronization (mail, instant messengers, cloud services)
  • 🔔 Notifications (social networks, news applications)
  • 🎵 Music playback (Spotify, YouTube Music)
  • 🗺️ Location tracking (maps, fitness trackers)

Android limits the number of such processes for a reason. The more there are, the more heavily loaded CPU (central processor) and RAM (RAM). This leads to two key problems:

  1. Reduced performance —the system spends resources on background tasks instead of active applications.
  2. Increasing power consumption —every background process drains the battery, even when you're not interact with the device.

Therefore, Android uses dynamic process management: closes the least priority tasks when there are not enough resources. The background process limit determines how many applications can remain in memory before the system begins to forcefully terminate them.

Where is the background process limit setting

This option is hidden in the menu for developers (Developer Options). To open it:

  1. Go to Settings → About phone (or About device).
  2. Find item Build number (or MIUI version on Xiaomi, Software version on Samsung).
  3. Tap on it 7 times in a row - a notification will appear "You have become a developer!" processes)
  4. Return to the main settings menu - a new section will appear there For developers.

Inside the developer menu, find the option: 

Do not save actions (Limit background processes)

On different devices it may be called a little differently, for example:

  • 📱 Samsung: Background processes limit
  • 📱 Xiaomi/Redmi/POCO: Limiting background processes
  • 📱 Google Pixel: Limit background processes
  • 📱 Realme/Oppo: Background process limit

After clicking, a list with limit options will open. But before changing the values, it is important to understand what they mean.

Why do manufacturers hide this setting?

This option is intended for testing applications and debugging performance. Arbitrarily changing the limit can upset the balance of the OS, so it is hidden from ordinary users.

Background process limit values: what each one means

In the developer menu you will see the following options. (exact wording may vary):

Value Description For which devices it is suitable
Standard limit Android itself regulates the number of processes depending on the available memory and load. Optimal for most users.
No background processes All applications close immediately after minimizing. Saves maximum battery, but slows down switching between tasks. Ultra-budget smartphones (1-2 GB of RAM) or devices with very worn-out devices. battery.
Maximum 1 process Only one application remains in the background (the last minimized one). The rest are closed. Weak devices (2-3 GB of RAM) with frequent freezes.
Maximum 2 process The last two minimized applications remain active. Mid-range smartphones (3-4 GB RAM).
Maximum 3 processes Three applications remain in the background. power consumption. Devices with 4-6 GB of RAM (for example, Redmi Note 10 Pro, Samsung Galaxy A52).
Maximum 4 processes Four applications in the background. Suitable for multitasking, but increases the load. Flagships with 6+ GB RAM (Google Pixel 7, Samsung Galaxy S23).

Critical feature: on devices with a small amount of RAM (less than 3 GB), setting the limit above 2 processes can lead to constant restarts of applications and lag. This is due to the fact that Android is forced to actively use swap (virtual memory), which slows down work.

💡

If you are not sure which value to choose, start with Maximum 2 processes and observe the behavior of the smartphone for 1-2 days.

When to change the limit of background processes

In most cases standard limit (automatic adjustment) is optimal. However, there are scenarios when manual adjustment is justified:

  • 🔋 Rapid battery drain - if the smartphone is discharged after several hours without active use, reduce the limit to 1-2 processes may help.
  • 🐢 Constant freezing - on weak devices (1-2 GB of RAM), increasing the limit to 3-4 will only worsen the problem. 1 process or No background processes.
  • 🔄 Frequent restarting of applications — if instant messengers or music players constantly reboot when returning to them, you can increase the limit to 3 processes (with sufficient RAM).
  • 🎮 Games and heavy applications - for gamers or users Adobe Photoshop, Lightroom it makes sense to increase the limit to 4 processesso that background tasks do not interfere with work.

It is important to understand: increasing the limit does not always improve multitaskingIf the device has little RAM, Android simply will not be able to hold more processes - they will be constantly unloaded, despite settings.

How to properly test changes

If you decide to experiment with the limit, follow this algorithm to avoid problems:

  1. Fix the current state:
    • Record how many applications usually remain in the background (you can use Developer Options → Running services).
    • Check the battery life in standard mode (for example, from 100% to 15%).
  • Change the limit and use the smartphone in normal mode minimum 24 hours.
  • Evaluate the changes:
    • Has it become faster to switch between applications?
    • Has the number of spontaneous closings of apps decreased?
    • How has the operating time changed from batteries?
    • Return to default settingsif the results are negative.

    For an objective assessment, you can use monitor applications, such as:

    • 📊 AccuBattery — to track battery consumption.
    • 📈 Simple System Monitor — to monitor usage RAM
    • 🔍 Developer Options (built-in) → Running services —to see which processes are active.
    💡

    The optimal limit of background processes is individual for each device. What works on Samsung Galaxy S22 with 8 GB of RAM can completely “kill” Redmi 9A with 2 GB of memory.

    Dangers and side effects of changing the limit

    Incorrect settings can lead to serious problems. Here are the most common ones:

    • ⚡ Accelerated battery drain —if you set the limit too high on a weak device, the system will be constantly overloaded, which will increase power consumption.
    • 🐌 Slowdown of the interface —if there is not enough RAM, Android will begin to actively use the swapfile (virtual memory on the drive), which slows down the work significantly.
    • 🔄 Frequent application restarts —paradoxically, on devices with a small amount of memory, increasing the limit can lead to the opposite effect: the system will be forced to close even priority tasks.
    • 🚨 System failures — in rare cases, incorrect settings can cause errors in the operation of Android, up to bootloop (loop loading).

    Owners of devices with entry-level processors (for example, Helio A22, Snapdragon 4xx) and a RAM capacity of less than 3 GB. On such smartphones, even a slight increase in the limit can make the system unstable.

    💡

    If, after changing the limit, the smartphone begins to slow down a lot, return the setting to Standard limit and reboot the device. This usually solves the problem.

    ⚠️ Attention! On some firmware (for example, MIUI from Xiaomi or One UI from Samsung), changing the limit of background processes may be reset after updating the system. Check the settings after installing new software versions.

    Alternative ways to optimize background processes

    If the goal is to improve performance or autonomy, you do not always need to change the limit manually. There are safer and more effective methods:

    • 🛑 Disabling autorun:

      Many applications launch automatically when you turn on your smartphone or connect to the Internet. Disable unnecessary ones in Settings → Applications → Autorun.

    • 🔄 Limit background activity:

      In the menu Settings → Applications → [select application] → Battery you can prohibit background work for individual apps.

    • 🗑️ Clear cache:

      Regularly clearing the application cache (Settings → Storage → Cached data) frees up memory and reduces system load.

    • 🔋 Power saving mode:

      Activating this mode automatically limits background activity, extending battery life.

    For advanced users, tools like ADB (Android Debug Bridge), which allow you to manage processes more flexibly. For example, the command: 

    adb shell am kill-all

    forcefully closes all background tasks, but it should be used with caution.

    ⚠️ Attention! Some “optimizers” from Google Play (for example, Clean Master, DU Speed Booster) promise to “speed up” the smartphone by closing background processes. In practice, they often make things worse by consuming additional resources. Android itself knows how to manage memory - do not interfere with it unnecessarily.

    FAQ: Frequently asked questions about the limit of background processes

    🔹 Why did some applications stop sending notifications after changing the limit?

    If you set the limit too low (for example No background processes), Android can forcefully close instant messengers and social networks that are responsible for push notifications. Return the limit to 2-3 processes or add the necessary applications to exceptions in the battery settings.

    🔹 Is it possible to set the limit of background processes above 4?

    On most devices the maximum value is 4 processes. However, on some custom firmware (for example, LineageOS), this limit can be increased through ADB or editing system files. This is extremely inappropriate recommendedas it can lead to unstable operation of the system.

    🔹 Does the limit of background processes affect games?

    Yes, but indirectly. If there are too many tasks running in the background, the game may start to slow down due to lack of resources. However increasing the limit will not improve FPS for games, free RAM and processor performance are more important. It is better to close all unnecessary applications before starting the game.

    🔹 Why is there no “Background process limit” option on my smartphone?

    Some manufacturers (for example, Huawei, Honor) remove this option from the menu developer in their firmware. An alternative is to use ADB-commands or third-party utilities like Activity Launcher, but this requires root access or an unlocked bootloader.

    🔹 Can changing the limit damage a smartphone?

    Setting the limit itself cannot physically damage device. However, incorrect values ​​can cause software failures: constant reboots, freezes, or even bootloop. In this case, resetting the settings to factory settings will help (Hard Reset).
