Modern smartphones based on Android have become smarter and more energy efficient, but this comes at a price. The operating system aggressively manages resources, often forcefully closing processes that are not in use right now. For the user, this often results in missed messages in instant messengers, stopped downloading files, or malfunctions of the smart watch.
Many device owners are faced with a situation where the application stops tracking geolocation or synchronizing data as soon as the screen is turned off. It's not a app failure, but a setting energy saving. Google developers and smartphone manufacturers (Samsung, Xiaomi, Huawei) are introducing increasingly strict algorithms for “killing” background processes to extend battery life.
In this article we will look in detail at how to return applications the right to run in the background without sacrificing battery life. You will learn what parameters need to be changed in the system settings so that important services function stably.
Why Android closes applications in the background
The operating system Android uses a complex memory and power management system known as Doze Mode. When the device screen is turned off and the phone is lying still, the system enters deep sleep mode. In this state, network activity is limited and background processes are suspended.
Equipment manufacturers often enhance these mechanisms with their own shells. For example, MIUI from Xiaomi or One UI from Samsung have preset optimization profiles that may be too aggressive for workloads. This leads to the fact that even standard applications like mail or calendar stop updating on time.
There are several levels of restrictions that can be applied to the app:
- 📉 Limiting background activity - the application cannot run processes when you are not using it.
- 🔋 Battery optimization - the system limits access to the network and sensors to save battery.
- 🚫 Forced stop - complete termination of the process when clearing RAM.
Understanding exactly what mechanism is blocking the operation of your software is the first step to solving the problem. Most often, it is enough to change just a couple of parameters to restore functionality.
Basic settings through the app menu
The simplest and most universal way to allow work in the background is to change the settings of a specific application through the system menu. This method works on most devices with “clean” Android and custom shells.
You need to find the desired app in the list of installed ones and go to its detailed settings. The interface may differ slightly depending on the firmware version, but the logic remains the same. Find the section responsible for battery or power consumption.
Follow these steps:
- Open
Settingsyour smartphone. - Go to section
ApplicationsorApplications and notifications. - Find the desired application in the list (for example, Telegram or Mail) and tap on it.
- Select an item
BatteryorBattery consumption. - Change the operating mode to "Unlimited" or
Do not limit.
⚠️ Attention: Setting the "Unlimited" mode may lead to to faster battery drain if the application is not optimized by the developers. Use this setting only for critical services.
After changing this setting, the system will no longer forcefully terminate the process of this application, even if you have not opened it for several days. This ensures that you receive push notifications and background data synchronization.
Setting features on different shells
Chinese smartphone manufacturers are known for their radical approaches to saving energy. Device owners Xiaomi, Huawei and Honor often face the fact that standard Android settings are not enough. This requires dodatkowa konfiguracja.
In the shell MIUI i HyperOS there is a hidden autorun mechanism. Even if you have allowed running in the background, the application may not start after rebooting the phone without explicitly allowing autorun. This is a unique feature of the Xiaomi ecosystem.
For devices Huawei with a shell EMUI or HarmonyOS adding the application to the protected list is critical. Without this step, the system will “kill” the process when the screen is locked, ignoring other settings.
Comparison of methods for popular shells:
| Shell | Key setting | Where to look | Additional. action |
|---|---|---|---|
| MIUI / HyperOS | Autostart | Applications → Permissions → Autostart | Fix in recent |
| One UI (Samsung) | Sleep applications | Battery → Restrictions in the background | Exclude from optimization |
| EMUI / HarmonyOS | Running applications | Battery → Launching applications | Disable auto control |
| ColorOS (Oppo) | Allow autorun | Phone Manager → Permissions | Pin to multitasking |
Don't forget that interfaces are updated. If you do not find the exact name of the item, look for synonyms related to startup or power management.
On Xiaomi smartphones, after setting up autorun, be sure to go to the multitasking menu (swipe up and hold), find the application and pull it down so that the lock icon appears. This will fix it in memory.
Working with power saving mode
Global power settings often take precedence over individual application settings. If your phone has "Power Saving" or Ultra Power Savingmode enabled, it can block background activity for all apps at once, regardless of your personal permissions.
In this mode, the system limits vibration, background data transfer and screen brightness. This mode is not suitable for normal operation of instant messengers and email clients. You need to either disable it completely or configure exceptions.
Check the following parameters:
- 🔋 Charge level to enable - make sure that the mode does not turn on automatically at 20-30% charge if you need communication.
- 📶 Background data - in economy mode, mobile data is often disabled for background applications.
- ⏰ Schedule - check if energy saving is configured to automatically turn on at night.
Sometimes users accidentally activate the “Super mode” of saving, which turns the smartphone into a dialer, leaving only a few selected applications to work. Exiting this mode is usually done by long pressing the power button or through a notification in the curtain.
⚠️ Attention: In extreme power saving mode, GPS trackers and health monitoring applications stop collecting data. Do not use this mode while jogging or driving if you need to track your route.
How to extend battery life without turning off background processes?
Reduce the screen refresh rate to 60 Hz, reduce the brightness, and turn off the always-on display (AOD). This will give a greater increase in autonomy than prohibiting messengers from working in the background.
Specific settings for messengers and trackers
Some categories of applications require a special approach. Messengers (WhatsApp, Telegram, Viber) and activity trackers (Google Fit, Strava) must have constant access to the network and sensors. For them, standard settings may not be enough.
Synchronization is critical for instant messengers. If notifications arrive with a delay, check your settings account synchronization. Go to Settings → Accounts, select your Google account or messenger account and make sure that the checkbox next to the desired service is active.
For fitness trackers and navigators, permission to work in the background is important when using geolocation. In the application permission settings, find the item Location and select the option "Allow always". The “Allow only when in use” option will stop recording the track as soon as you turn off the screen.
Often, additional fixation of the application in RAM is required. Open the recent applications menu (square button or swipe), find the card of the desired app and click on the lock icon or hold your finger until the lock icon appears. This will prevent the application from closing when clearing memory with the Close All button.
Advanced methods: Debugging and ADB
If standard methods do not help, you can use developer tools. This is relevant for advanced users who want complete control over the behavior of the system. Using ADB (Android Debug Bridge) allows you to remove restrictions that are not visible in the regular menu.
First you need to activate developer mode. Go to Settings → About phone and quickly click 7 times on the item Build number. After this, a new section will appear in the settings menu For developers.
In this section, find the item Background process limit. Make sure that the value is set there "Standard limit". Sometimes users accidentally set a limit of 0 or 1 process, which breaks the operation of the entire system.
For in-depth configuration, you can use commands through the computer. Connect your phone via USB and enter the command to disable battery optimization for a specific package:
adb shell dumpsys battery unplugHowever, a more useful command is to remove restrictions via appops, but this requires superuser rights or specific ADB permissions, which may reset after a reboot. A more reliable way is to use special utilities like SuperFreezZ or Hail, which control the freezing of applications, but require configuration via ADB upon first launch.
☑️ Checklist for checking background work
⚠️ Attention: Changing settings via ADB or developer mode may lead to unstable system operation. If you are not sure of your actions, it is better to limit yourself to the standard settings menu.
The main reason for problems with the background is the aggressive optimization of the battery by the manufacturer. The solution lies in disabling restrictions for specific applications, and not in global system settings.
Frequently asked questions
Why does the application close immediately after minimizing?
Most likely, the “Optimize” or “Hard Limit” mode is selected in the battery settings for this application. Change it to “No restrictions” and check if the global power saving mode is turned on.
Does background work affect the speed of the phone?
Many active background processes can take up RAM, which sometimes leads to a sluggish interface on weak devices. However, modern processors can easily handle dozens of background tasks without loss of performance.
How to check which application is consuming the most battery in the background?
Go to Settings → Battery → Battery usage. There will be a list of applications with percentages. Pay attention to the “Background activity” column.
Is it possible to completely prevent all applications from running in the background?
Technically, this is possible through the mode “Do not disturb” or special profiles, but this will make the smartphone almost useless for communication. You will not receive calls or messages until the screen is unlocked.
Are background settings reset after updating Android?
With major Android version updates (for example, from 13 to 14), permissions and battery settings may be reset to default values. After a major update, it is recommended to recheck critical applications.
