Modern smartphones based on Android strive to save battery power as much as possible, often at the expense of functionality. Users often encounter a situation where the navigator stops getting directions when the screen is off, and messages in instant messengers arrive with a delay. This happens because the operating system forcibly limits the activity of running processes.
Allowing it to run in the background means giving a specific application the right to function, even if you minimized it or locked the device screen. Without this permission background activity is blocked by aggressive energy saving algorithms installed by shell manufacturers like MIUI, OneUI or ColorOS.
In this guide we will look at all the nuances of setting up the system so that your important apps work stably. You will learn how to manage permissions, disable battery optimization, and understand which processes are truly safe to run continuously.
The concept of background work and system limitations
Background operation of an application involves performing tasks without active user participation. This could be downloading files, playing music, tracking geolocation, or synchronizing data. The operating system Android was initially designed to suspend unused processes to save resources.
However, with the release of new versions of the OS, the policy became stricter. Starting Android 8.0 Oreo, strict limits were introduced on running services in the background. If an application tries to start a service while the user is interacting with another window, the system can simply stop this process. Limiting background processes has become an industry standard for combating battery drain.
The situation is aggravated by custom skins from manufacturers. Companies Xiaomi, Huawei and Samsung often implement their own, even more aggressive memory cleaning algorithms. They can "kill" a process a few minutes after minimizing the window, considering it inactive, even if it should be running constantly.
- 📱 Standard Android restrictions block new services from starting in the background.
- ⚡ Aggressive energy saving by manufacturers often stops needed apps.
- 🔄 Data synchronization and push notifications require special permissions.
⚠️ Attention: Uncontrolled launch of dozens of applications in the background can lead to rapid battery drain and overheating of the case. Allow background work only to proven and necessary apps.
Understanding these mechanisms is necessary for proper configuration. You don’t just turn on the toggle switch, but let the system understand that specific software is an exception to the rules for saving energy.
Basic permission settings in Android
The first step should always be to check the standard permissions in the settings menu. This is the foundation, without which further manipulations may not make sense. You need to find the section responsible for managing applications, which may be called differently in different versions of the OS.
On a clean Android path usually looks like this: Settings → Applications → Manage applications. Here you need to select a specific app, for example, a navigator or messenger. Inside the application menu, we are interested in items related to battery and permissions. This is where the switch is hidden that allows you to bypass standard restrictions.
It is important to pay attention to the item “Battery consumption” or “Battery”. It often contains the “Limit background activity” or “Battery saver” setting. If the “Limited” or “Save battery” checkbox is checked, the system will strictly control the operation of the app. You must select the option "No restrictions" or "Do not limit."
After changing these parameters, the system will no longer forcefully terminate the process when there is insufficient memory. However, on some devices this is not enough, and a deeper dive into the settings is required.
Battery management and optimization
The central element for managing background tasks is the battery menu. Modern smartphones are equipped with intelligent systems that analyze user behavior and offer to optimize the operation of the device. Often this "optimization" consists of disabling background services.
To get full control, you need to go to Settings → Battery → More (or "Battery consumption"). Here is a list of all installed applications. Find the app you need and click on it. You will see the current status of energy consumption and operating mode.
The key point is selecting the operating mode in the background. Typically there are three options: "Limited", "Optimized" and "Unlimited". For stable operation of trackers, smart watches or important messengers, you must select the latter option. This action removes all restrictions on energy consumption from the app.
| Operating mode | Impact on the battery | Impact on the operation of the application | Recommendation |
|---|---|---|---|
| Limited | Minimal | The application closes immediately after minimizing | For rarely used games |
| Optimized | Medium | The system decides when to stop process | For most standard applications |
| No restrictions | High | The application runs constantly, even in the background | For navigators, trackers, instant messengers |
⚠️ Attention: Interface The battery menu may differ depending on the Android version and smartphone model. Look for items that are similar in meaning if the exact names do not match.
Do not forget that removing restrictions from a large number of applications will lead to a noticeable decrease in autonomy. Use this method selectively, only for those apps that really need to work 24/7.
Specific settings for different manufacturers
Owners of smartphones from different brands are faced with unique interface features. Manufacturers are actively modifying the standard Android, adding their own task managers, which often override system settings.
On devices Xiaomi (MIUI/HyperOS shell) there is a separate "Security" application. Inside it you need to find the “Battery” section and go to “Activity Control”. Here you can set the status “No restrictions” for each application. Without this step, even Android system settings may be ignored.
Users Samsung should pay attention to the "Auto-optimization" function. It is located in the device maintenance menu. Also in new versions of OneUI, a separate list of “Applications in deep sleep” has appeared, which are completely blocked in the background. Make sure that the desired app is not included there.
- 📱 Xiaomi/Poco: Requires setting in the "Security" application and enabling autorun.
- 🌌 Samsung: Checking the "Deep sleep" and "Unused applications" lists.
- 🔵 Huawei/Honor: Manually blocking the application in the task manager is required (lock).
Secrets of Huawei and Honor
On devices of these brands, manually locking the application in the running tasks menu often helps. Press the Menu (square) button, find the app window you want, and drag it down until the lock icon appears. This will prevent the system from closing the app when clearing the memory.
If you are using a smartphone of another brand, look in the settings for sections called “Launch applications”, “Task Manager” or “Memory management”. The logic is the same everywhere: you need to find a app and remove all restrictions from it.
Advanced developer options
For advanced users, there is a “For Developers” menu, where deep system settings are hidden. You can get there by quickly clicking on the build number in the “About phone” section several times. This will open access to hidden OS control levers.
In this menu you should find the "Applications" section. There may be a “Background process limit” item. By default it is set to "Standard Limit". Changing this setting to "No restrictions" allows all applications to run in the background, but this it is highly not recommended to do it globally due to the risk of overloading the RAM.
A safer method is to use ADB debugging if standard methods do not help. Commands via the computer allow you to force whitelist an application, making it systemically important. However, for the average user, the settings described in the previous sections are sufficient.
adb shell dumpsys package com.example.app | grep mWakefulnessThis command (example) allows you to check the package activity status, but graphical interfaces are more often used to enable the background. The main thing in the developer menu is not to change the settings accidentally, so as not to disrupt the stability of the entire system.
If you accidentally changed the settings in the developer menu and the phone began to work unstable, find the "Reset settings" button at the very bottom of this menu or simply disable the entire developer mode.
Solving problems with stopping services
Even after all the settings, situations may arise when the application still stops. This is often due to a lack of random access memory (RAM). When the system does not have enough resources, it begins to close background processes, ignoring permissions.
In such cases, fixing the application in memory helps. Open the menu of running applications (Menu button or swipe from bottom to top with a delay). Find the window of the desired app and click on the lock icon or select the "Lock" option. This is a signal to the system that this window is a priority.
It is also worth checking for updates for the application itself and the operating system. Bugs in the app code can lead to its incorrect completion. Developers often release patches that fix problems with background work on new versions of Android.
☑️ Diagnostic checklist
If nothing helps, try deleting the application and installing it again. When you first start, the system will ask for permissions again, and you can immediately grant all the necessary rights, which sometimes resets erroneous configurations.
Security and impact on autonomy
By allowing work in the background, you must be aware of the consequences. Constant activity means constant use of the processor, communication modules and, possibly, GPS. This directly affects battery life.
In addition, background work opens up potential privacy risks. An app running in the background may collect data about your location or activity even when you're not using it. Trust such rights only to trusted software.
It is recommended to periodically check battery consumption statistics. If you notice that after enabling background work, an application begins to consume an abnormally large amount of energy, it may have a bug in its code or it is mining cryptocurrency.
⚠️ Attention: If an application that does not need constant communication (for example, a calculator or photo editor) requires background work, this is suspicious. Revoke permission and check the app with an antivirus.
The balance between functionality and autonomy is the key point. Enable background work only for those applications whose functionality critically depends on a constant connection and activity.
Proper permission management allows you to make your smartphone smarter. You decide which processes are important and which can be stopped to save charge.
Frequently asked questions (FAQ)
Why does the application still turn off after all the settings?
Most likely, the manufacturer's aggressive memory manager is interfering. Try to find the application in the running list and block it (lock icon). Also check if the “Energy Saving” mode is active throughout the system.
Is it harmful to keep many applications in the background?
Modern Android knows how to manage memory correctly. Applications in the background are in a “frozen” state and do not consume processor resources until they are needed. Only active background activity (GPS, network) causes harm, and not just being in memory.
How to disable background work for all applications at once?
Turn on the "Hard Energy Saving" or "Airplane Mode" mode. Also in the "For Developers" menu, you can set the limit of background processes to "0" or "1", but this will make working with the phone uncomfortable.
Do you need to allow autostart for all apps?
No, autostart is needed only for those applications that should start working immediately after turning on the phone (antiviruses, instant messengers, alarm clocks). For others, this is just an extra load on the system at startup.
Are settings reset after updating Android?
Often after a major system update, permission settings and battery settings can be reset to factory values. It is recommended to check key applications after updating the firmware.
