Modern mobile games often require a constant connection to the server and an active rendering process, which creates a conflict with the system's aggressive power saving policy Android. Users frequently encounter situations where, when minimizing an application or locking the screen, the game process is interrupted, the connection to the server is lost, and progress is lost. This is especially true for MMORPGs, real-time strategy games and games with auto-combat, where the character must act continuously.
The problem is not a developer error, but the way the operating system manages resources. Background processes are limited by default to extend battery life. However, knowing the system settings and using special tools, you can force the game to remain active even when the display is turned off. In this article, we will look at legal methods of setting up the system, working with the developer menu and advanced methods via a computer.
It is worth noting right away that there is no universal “Enable background” button, since each shell manufacturer (MIUI, OneUI, ColorOS) implements its own “task killer” algorithms. You will have to take a comprehensive approach, changing power settings, notifications and network activity for a specific application.
Why Android closes games when minimized
Operating system Android designed so that the application, which the user does not see on the screen, consumes a minimum amount of resources. When you press the Home button or minimize the game window, the system switches the process to state caching. If at this moment the device requires more RAM for other tasks or the energy saving timer is triggered, the system ends the game process without warning.
Chinese shells are particularly aggressive, such as MIUI ot Xiaomi or HyperOS. They have built-in deep cleaning services that can close the application within just a few seconds of locking the screen. This is done for marketing purposes - so that the phone shows record battery life in benchmarks, sacrificing functionality.
⚠️ Attention: Forcing heavy 3D games in the background when the screen is off can lead to overheating of the device and accelerated battery degradation, as the GPU continues to work at full capacity.
In addition, many games themselves are programmed to pause when focus is lost. If the developer has not implemented an "AFK" or "Background Mode", then even the system settings will not help start graphics rendering when the screen goes dark. In such cases, the game may continue to download data, but the visual part will stop.
Setting power saving mode for applications
The first and most important step is to exclude the game from the list of optimized applications. In the standard settings Android there is a mechanism that “puts to sleep” apps that you rarely use or that run for a long time. We need to switch the game to "No restrictions".
The algorithm of actions may differ depending on the OS version, but the general path usually lies through the app menu. You need to find the specific game in the list of installed apps and change the battery consumption setting. This will give the system a signal that this application is a priority and should not be terminated to save battery.
On clean Android and most stock firmware, the procedure is as follows:
- 📱 Go to
Settingsand select the partitionApplications. - 🔍 Find the game you want in the list and click on it.
- ⚡ Go to
BatteryorBattery consumption. - 🚀 Select operating mode
No restrictions(Unrestricted).
After completing these steps, the system will no longer limit the background activity of the game. However, on Samsung or Xiaomi devices, additional steps may be required, such as pinning the application to the recent tasks menu or adding it to the "White List" of the task manager.
If there is no "Unlimited" option, try disabling the "Adaptive Battery" feature in the general power settings, it often blocks the background work of new games.
Working with notifications and screen locking
Many users do not know that having an active notification can keep an application in memory. The way it works is this: if an application has a visible notification, the system believes that it is performing an important task for the user in real time. This is a simple but effective trick for keeping the game in the background. Android is that if an application has a visible notification, the system believes that it is performing a task that is important to the user in real time. This is a simple but effective trick to keep the game in the background.
Check the notification settings for your game. Make sure they are not disabled completely. In some cases, it is useful to enable notifications to appear on the lock screen. This will prevent the process from completely freezing when the display is turned off, as the system will continue to update the status bar.
It is also worth paying attention to the setting “Do not turn off the screen” in developer mode if your goal is to leave the game working visually, but without touching. Although this is not exactly a background mode in the classical sense, it solves the problem of turning off when idle.
| Manufacturer | Function name | Where to find | Efficiency |
|---|---|---|---|
| Xiaomi / POCO | Autostart | Applications → Permissions | High |
| Samsung | Sleep applications | Battery → Restrictions background | Medium |
| Huawei / Honor | Launch applications | Battery → Launch applications | High |
| OnePlus / OPPO | Allow autorun | Manager applications | Average |
Please note that interfaces are updated regularly. If you do not find the specified items, use the search inside the settings using the keywords “battery”, “autostart” or “background activity”.
⚠️ Attention: The settings interface may differ depending on the firmware version. If you don't have an exact match, look for similar power management features in the Special Features section. Features" or "Security".
Using the developer and debug menu
For deeper settings, you can use the hidden developer menu. Here are the parameters that directly affect how the system manages processes. One of the key parameters is the limit of background processes. By default, it can be set to a standard value, which we can change.
To get to this menu, you need to activate developer mode. This is usually done by repeatedly clicking on the build number in the About phonesection. After activation, a new item will appear in the main settings For developers.
Inside the menu, find the section Applications or Background processes. Make sure that the value is selected Standard limit or set the maximum number of processes if such an option is available. It is also useful to disable the option "Do not save actions"if it is enabled, since it destroys the activity immediately after leaving the application.
adb shell settings put global background_process_limit 0This command, entered through a computer with ADBinstalled, removes the limit on the number of background processes at the system level. This is a powerful tool, but should be used with caution, as too many active processes can slow down the entire device.
How to enable USB debugging?
Go to the developer menu → Find the “USB Debugging” item → Connect your phone to the PC → Confirm the key fingerprint on the screen smartphone.
Advanced methods through ADB and third-party utilities
If the standard settings do not help, you can use the tool Android Debug Bridge (ADB). This is a console utility that allows you to send commands to the system directly, bypassing the graphical interface. With its help, you can prevent the system from putting a specific application to sleep.
Command dumpsys allows you to see the current state of processes, and command am (Activity Manager) can control their launch. However, the most effective method is to use special scripts or utilities, such as Battery Guru or Greenify (in operating mode without root access), which automate the process of setting exceptions.
For manual control via the console, you can use the following sequence of actions. It requires a connected computer and an installed device driver:
- 💻 Connect the smartphone to the PC with a cable.
- ⌨️ Open the command line in the folder with ADB.
- 📱 Enter the command to get a list of packages:
adb shell pm list packages. - 🛠️ Find the package name of your game (for example,
com.game.name).
Next, you can try to disable battery optimization for this package through the command dumpsys battery, but this method is unstable on new ones versions Android 12-14. A more reliable way is to use commands to disable Doze mode for a specific application, although this requires superuser rights in some cases.
Using ADB gives maximum control over the system, but requires technical knowledge and having a computer on hand for the initial setup.
Features of working on different versions of Android
Starting with version Android 8.0 Oreo, Google introduced strict restrictions on the background execution of services. Applications can no longer simply register services in the background. Game developers were forced to switch to the use of Foreground Services (foreground services), which necessarily show a notification.
B Android 10 and newer, restrictions have been added on access to the location and clipboard in the background, which can also affect the operation of some game mechanics. Android 12 a feature called “Suspend cached applications” has appeared, which freezes processes even more aggressively to free up RAM.
On the latest versions, such as Android 14, the system may automatically restrict the operation of applications that you have not opened for several days. Therefore, it is important to periodically launch the game in active mode to reset the unused counters.
⚠️ Attention: On Android 13 and higher, the system may automatically revoke permissions from applications that have not been used for a long time. Check to see if network access for your game has been disabled. data-i="148">Attention:
Frequently asked questions (FAQ)
Is it possible to run a heavy 3D game with the screen completely turned off?
Technically this is possible if the game supports rendering without a display, but in 90% of cases modern engines (Unity, Unreal Engine) pause frame rendering when the screen is turned off to save energy. The game may continue to download data, but the world will “freeze.”
Why does the game work in the background on Wi-Fi, but turns off on the mobile data?
This is due to the traffic saving settings. In the application settings, check the “Traffic saving” item and allow background data transfer specifically for mobile networks. Telecom operators and the system can block background traffic to save your limit.
Is it safe to use ADB commands to unblock the background?
Using standard ADB commands to change battery settings is safe and does not require root access. However, you should not enter commands that you do not understand, especially those related to removing system packages, as this can lead to unstable operation of the system.
How to fix a game in memory on Xiaomi?
Open the recent tasks menu (square button), find the game window, hold it with your finger and click on the lock icon. This will prevent the application from closing when clearing the memory with the “Cross” button, but will not save you from an aggressive process killer when the screen is locked without adjusting the battery.
Does running in the background affect battery wear?
Yes, a significant impact. If the processor and radio are running constantly, the battery will drain faster and become hotter. Prolonged heat is the main enemy of lithium-ion batteries and reduces their service life faster than charge-discharge cycles.
