Xiaomi’s Poco X3 lineup is well-deservedly considered one of the most powerful mid-range devices, but even powerful hardware can have trouble with multitasking over time, especially if the user is actively installing a variety of programs from various sources. The accumulation of running processes in RAM is a natural process that can lead to a slowdown in the interface and a quick battery drain.
The Android operating system in the MIUI shell has its own memory management features that differ from pure Android. Often built-in cleaning mechanisms can not cope with aggressive applications that continue to consume resources even after you close their screen. In this guide, we will discuss in detail how to effectively disable background applications on Xiaomi Poco X3 to return the device to its former aspiration.
Understanding how the background mode works will help you not just mechanically close programs, but correctly configure the system. We will consider both the standard shell tools and more advanced methods available to owners of the Poco X3 NFC and Poco X3 Pro. Pro Pro Pro Pro Pro will significantly extend the battery life of your gadget.
Task Manager and Quick Memory Cleanup
The easiest and most obvious way to free up resources is to use a built-in Task Manager, which is implemented as a “Trash” or “Clean” button on Xiaomi smartphones in recent apps, but many users underestimate the tool’s capabilities by using it only to remove cache, when it can force processes to stop.
To access the list of running applications, you need to click the Menu navigation button (square or three stripes) or swipe from the bottom up with a delay, depending on the type of navigation you choose. In the list that opens, you will see cards of all running programs. Pressing the cross or the Clear All button forcibly terminates the processes, freeing RAM.
⚠️ Continuous forced cleaning of all applications can negatively affect the speed of the system, as Android is forced to restart system processes, which consumes more power than their storage in memory.
It's important to distinguish between simple folding and complete shutdown. Some applications, such as messengers or navigators, can continue to work in the background even after cleaning the list of recent tasks unless they have set limits, so task manager is just the first step in optimizing, not a panacea for all the performance problems.
Configure background activity restrictions in MIUI
The MIUI shell provides a more flexible tool for managing application power consumption, which is deeper in the system settings, where you can prevent specific programs from running or running in the background, which is especially true for games and heavy social networks, and this allows you to save battery power for really important tasks.
To get into the restriction menu, follow the Settings → Applications → Battery and Performance (or Charge Savings) path. In the list that opens, you will see all the programs installed. By clicking on a particular application, you can choose its strategy. For programs that you do not need in the background, the option “Limit background activity” or “Strict restriction” is ideal.
- 📱 Without restrictions: the application can work in the background without restrictions, obtaining full rights to use the network and the processor.
- 🔋 Charge savings: The system will limit background activity when the screen is off, which helps save energy.
- 🚫 Hard Limit: The app won’t be able to run in the background and receive notifications until you open it again.
Using a tight restriction is a radical but effective method for parasitic apps that constantly mine cryptocurrency or collect telemetry data. However, it is worth remembering that in this case you will stop receiving push notifications from such programs. So for instant messengers like Telegram or WhatsApp, it is better to choose the mode “No limits” or “Saving charge” so as not to miss important messages.
☑️ Checking battery settings
Hiding and freezing applications
Poco X3 owners have another powerful tool in their arsenal, Application Hiding, which, while originally conceived for privacy, technically also limits the background activity of hidden programs, and when an application is hidden, the system often stops its background processes to hide its presence.
To activate this feature, go to Settings → Applications → Hidden Applications. Turn on the switch for programs you rarely use but do not want to delete. After that, to run the hidden application, you will need to unlock it through a special code or fingerprint in the gallery or file manager, which in itself is a barrier to background activity.
| Management method | Impact on the battery | Impact on notifications | Difficulty setting up |
|---|---|---|---|
| Cleaning up memory | Low. | Temporary disappearance | Low. |
| Limitation in settings | High. | Total shutdown | Medium |
| Hiding the application | Average. | Depends on the OS. | Low. |
| Developer mode | Maximum. | Total shutdown | Tall. |
It is worth noting that on different versions of MIUI (Global, EU, China), the behavior of hidden applications may differ, in some builds, hiding completely equates to turning off, while in others the application simply hides from the launcher, but continues to work, so this method is better used in conjunction with other settings for maximum effect.
Developer Mode and Process Limit
For advanced users who want to take full control of their Poco X3, there is a Developer Menu, a hidden section of the system where you can manually set a limit on the number of background processes, and it is the only way to globally limit the number of applications running simultaneously for the entire system, rather than for each program separately.
To activate the developer menu, go to Settings → About Phone and quickly click on the MIUI version 7 times. After the message "You became a developer" appears, you can go to Settings → Additional Settings → For developers. Find the "Applications" section and select "Limit background processes".
Path: Settings -> Additional settings -> Developers -> Background Process Limit -> No more than 2 processesChoosing a “No More than 2 Processes” or “No Background Processes” option will force the system to aggressively close everything that is not in the foreground, which can dramatically speed up the old device, but make multitasking impossible: when switching between applications, they will reboot each time, which also consumes the battery.
Risks of changing the process limit
Auto Start and Work in the Background
One of the features of Xiaomi’s ecosystem is that it has a separate auto-run permission, which even if you close an app, can start itself when you turn on your phone or when you start a connected service, and controlling this setting is critical to preventing RAM from bloating.
Autorun control is located in the Safety app (green lightning icon). Go to Permissions → Autorun. Here you will see a list of all programs that are allowed to run themselves. It is recommended to leave autorun only for messengers, alarms and antiviruses.
- 🚀 System Processes: Do not disable Auto-Run for Google, Mi Cloud, and System Components MIUI, This can lead to unstable work.
- 💬 Messengers: Require permission to autorun and work in the background to receive messages in a timely manner.
- 🛒 Store Apps and Services: Disable Auto-Run for Delivery, Taxi and Store Apps, You Only Need Them When You Open Them.
Also on the same Security menu is the "Background" option, so make sure it's set up in a similar way to auto-run, and if an app has a permission to run in the background but it's disabled, it can still start, but only after you've opened it manually at least once.
💡
Check the autorun list regularly after installing new apps, as many programs automatically prescribe themselves there without the user’s knowledge.
The effect of background processes on battery and heating
The Poco X3 Pro is known for its powerful Snapdragon 860 processor, which, however, is prone to heat under intense loads. Background applications, especially those that use geolocation or constantly update tape, can cause invisible but constant heating of the case even in standby mode.
The constant activity of the processor in the background not only warms the device, but also accelerates the degradation of the battery. Lithium-ion batteries do not tolerate frequent heating cycles. By turning off unnecessary background processes, you not only save charge, but also prolong the physical life of your smartphone.
⚠️ Warning: If the phone is warming even after disabling all background apps and restarting, it may indicate a hardware problem or a system infection by a miner virus requiring a deeper diagnosis.
To monitor what is using up, use the built-in statistics in Settings → Battery → Charge Consumption. Here you can see which applications have worked in the background the most time, and if you see a program that hasn't been used for several days, but it's on the lead, it's a direct candidate for removal or severe restriction.
💡
An integrated approach to background control allows you to reduce the heating of the Poco X3 body by 15-20% and extend the operating time from one charge for 1-2 hours.
