Random access memory (RAM) in smartphones based on Android 10 is a critical resource, the volume and speed of which directly determines the performance of your device. When the amount of RAM is exhausted, the system begins to forcefully stop running processes, which leads to freezes, long application loading times, and even interface reboots. Unlike older versions of the operating system, the “ten” has more aggressive memory management, but background processes can still quietly “eat up” free resources.
Cleaning RAM on Android 10 is not just a “close all” button that many users press out of habit. This is a comprehensive approach that includes analysis of background services, startup management, and proper configuration of system parameters. We will look at both software and hardware methods for freeing memory that will help return your Xiaomi Mi 9 or Samsung Galaxy S10 former operating speed without losing important data.
In this article you will find step-by-step guide that will allow you to independently diagnose "gluttonous" applications and optimize their operation. We will not recommend dubious “booster” apps, which often themselves consume more resources than they save. Instead, we will focus on standard system tools and proven administration methods.
Diagnostics of the current state of RAM
Before taking any cleaning actions, you need to understand exactly what is taking up space in your RAM. Standard Android 10 settings do not always provide detailed information about each process, so we will have to use hidden system capabilities or special utilities. First, you should check the basic status through the developer menu, if you have already activated it.
To get accurate data, go to the section Settings → About phone and quickly click on the item seven times Build number. After the “You have become a developer” notification appears, return to the main settings menu and find the new section System → For developers. Here we are interested in the item Memory or Services, which will show a detailed breakdown of RAM usage by category: applications, cache, system processes.
Analysis of these statistics often reveals unexpected results. For example, you may find that an instant messenger app you haven't used for three days holds 200MB of data in memory for instant notifications. Or a system service Google Play Services is consuming an abnormally large amount of resources due to a synchronization error.
- 📊 Check the average free RAM for the last 3 hours or 6 hours in the developer menu.
- 🔍 Pay attention to applications marked "Cached" - they take up space, but they can be safely unload.
- ⚙️ Examine the list of Running Services to find hidden background processes.
⚠️ Attention: Do not try to forcefully terminate system processes with names containing
android,systemorcom.androidunless you are sure of their purpose. Stopping critical services can lead to unstable operation of telephony or the sensor.
Standard cleaning methods through the multitasking menu
The simplest and most obvious way to free up RAM in Android 10 is to use the built-in task manager, called up by the "Square" navigation button or a swipe gesture from bottom to top with hold. However, many users make the mistake of closing applications one at a time, which is time-consuming and not always effective. The Android 10 system is optimized to work with a large number of open tabs, but manual cleaning is still useful if there are obvious signs of slowdown.
When you click on the review running applications button, you will see cards of all active apps. At the bottom of the screen (or at the top, depending on the firmware of your Huawei P30 or Honor 20) there is usually a "Clean" button or a broom icon. Clicking it terminates application processes that are not system-critical. It is important to understand that this method only clears the user layer, leaving system services untouched.
Interestingly, in some shells, such as MIUI or OneUI, long pressing the clear button can bring up additional functions, such as speeding up the system or cleaning up fragmented memory. These are built-in marketing tricks from manufacturers that can really give a short-term performance boost by freeing up small blocks of memory.
If the "Clear All" button is inactive or missing, try holding down the icon of a specific application in the multitasking menu - often the "Close" or "Application Information" item appears there, allowing you to forcefully stop the process.
It is worth noting that constant manual cleaning all applications may have the opposite effect. When you close an application completely, the next time you start the system, it has to reload its code and data from the internal storage into RAM, which consumes more processor and battery power than simply switching between already loaded tasks.
Managing startup and background processes
The main enemy of free RAM is startup. Dozens of applications strive to launch along with the system in order to be ready to work at any second. Background activity restrictions have become stricter in Android 10, but many developers are getting around these restrictions by using accessibility services or persistent notifications. To effectively clean RAM, you need to prevent unnecessary apps from starting automatically.
Depending on the manufacturer of your device, startup settings may be located in different places. On pure Android 10 (Pixel, Motorola) you need to go to Settings → Applications and notifications → Advanced → Special access → Battery optimization. Here you can select the "All applications" mode and prevent specific apps from running in the background. On devices with custom firmware, such as Xiaomi or Oppo, there is often a separate "Autostart" item in the security or application settings.
Settings → Applications → [Select app] → Battery → Background activity → Limit
Disabling background activity is a powerful tool. When you select the Restrict or Hard Restrict option, the system kills the application process as soon as you minimize it from the screen. This guarantees the maximum amount of free RAM, but has a side effect: you may stop receiving notifications from this application until you manually open it.
- 🚫 Disable auto-start for games, browsers and food delivery services - they are not needed in the background all the time.
- 🔔 Leave background work only for instant messengers, email clients and alarm clocks.
- 🛡️ Check the "Display on top of other applications" rights - this is often how advertising modules that eat up memory work.
| Application type | Recommended background mode | Impact on RAM | Risk of missing notifications |
|---|---|---|---|
| Messengers (Telegram, WhatsApp) | Unlimited | Average | High (if limited) |
| Social networks | Limited | High | Low (notifications will come when opened) |
| Games | Hard limit | Critical | Absent |
| News aggregators | Limited | Average | Average |
Correctly setting up background activity is more important than regular manual cleaning Once configured, restrictions work continuously, saving your resources without user intervention.
Using developer mode to force a stop
If standard methods do not help return the desired performance, you can use the advanced tools available in developer mode. This section contains settings that allow you to control system behavior at a deep level, including limits on the number of background processes. Be careful: incorrect settings here can make the phone inconvenient to use.
One of the most powerful functions is to set a limit for background processes. By default, the system itself decides how many applications to keep in memory. You can force it to keep no more than 2 or 3 processes in RAM. As soon as you open the fourth application, the first one from the list will be immediately destroyed. This is a radical method, but it ensures that the active application will always have the maximum available memory.
Find the option in the developer menu Background process limit (No background processes). Select the "No more than 2 processes" option. Now when you switch between browser and camera, the system will aggressively unload everything else. This is especially useful on devices with 3 GB of RAM or less, where every megabyte counts.
⚠️ Attention: Setting the background process limit to "No background processes" may cause the music to stop immediately after the screen turns off, and the navigator to reset the route. Use this mode only to solve specific performance problems.
Another useful option is Don't save activities (Don't keep activities). When this feature is enabled, the system destroys application activity as soon as the user leaves the screen. This emulates the behavior of a device with very little memory and is useful for testing, but can be too aggressive for daily use, forcing apps to restart every time you switch.
What is the "Background Limit" in Android 10?
This is a setting that tells the system scheduler (Low Memory) Killer) kills processes as soon as their number exceeds a specified threshold. Unlike manual cleaning, this works automatically and constantly, preventing the accumulation of “garbage” in the memory.
Third-party utilities: benefit or harm?
There are hundreds of applications in the Google Play Market that promise to “speed up your phone” and “clean up RAM” in one click. The popularity of apps such as Clean Master, CCleaner or Greenifyis due to the desire of users to find a simple solution to complex problems. However, in the context of modern versions of Android, including version 10, the need for such tools is often questioned by experts.
The problem with most "cleaners" is that they themselves are applications that must run in the background to monitor memory. They consume processor and battery resources, creating a paradoxical situation: a memory-saving app itself consumes memory. In addition, aggressive process termination by third-party utilities can disrupt Android system mechanisms that attempt to restart important services.
However, there are exceptions. The utility Greenify, for example, works on the “hibernation” principle. It doesn't just kill the process, but puts the application into sleep mode, from which it will not be able to exit until you open it yourself. This is a gentler and more effective method for dealing with “parasitic” applications that constantly try to restart.
- 📉 Avoid applications with flashy advertising and promises to “increase RAM by 200%” - this is technically impossible.
- ✅ Use built-in cleaning tools if your firmware has them (for example, "Cleaning" in MIUI).
- 🔒 Check the permissions of third-party utilities - they do not need access to your contacts or calls to clear memory.
If you still decide to use third-party software, give preference to tools from well-known antivirus vendors or system utilities that have a transparent privacy policy and are not overloaded with advertising modules.
Radical measures: resetting settings and updating software
When software methods are exhausted and the phone continues to slow down due to lack of memory, it is worth considering more global solutions. Sometimes the problem lies not in specific applications, but in accumulated system errors, damaged caches or conflicts after many updates. In such cases, clearing RAM becomes temporary. a measure that does not solve the root of the problem.
The first step should be to look for system updates. Google engineers and device manufacturers are constantly releasing patches that optimize the operation of the memory manager. Go to Settings → System → System update and check for new versions. Often in the release notes you can see the phrase “improved system stability” or “optimized memory usage”, which directly concerns. our topic.
If the update does not help, the last resort is to reset to factory settings. This action will completely clear the internal memory and RAM of user garbage, returning the phone to the “out of the box” state be sure to create a backup copy of all important dataas the process. will delete all photos, contacts and installed applications.
⚠️ Attention: Before resetting the settings, make sure that you remember the password for your Google account. After rebooting, the phone will require you to enter the account data that was synchronized earlier (FRP protection). Without this, you will not be able to activate the device.
☑️ Preparing to reset the settings
After performing the reset, do not rush to install all applications at once. Start with the basic set and monitor memory consumption. Installation one by one will help identify the very application that caused problems with RAM in the past.
Why does the memory quickly fill up again after clearing the RAM?
This is normal Android behavior. The system tends to use all available RAM to cache frequently used applications so that they open instantly. Free RAM is wasted RAM. You should only worry if the filling is accompanied by interface sluggishness.
Harmful. Is it possible to constantly clear RAM on Android 10?
Frequent forced cleaning can increase battery consumption. Processes require more energy to cold start (boot from disk into memory) than to maintain activity in the background. Use cleaning only if there are clear signs of low resources.
Can a virus fill up RAM?
Yes, malware can create many background processes, mine cryptocurrency or send spam, which leads to 100% RAM utilization. If cleaning does not help, check the device with an antivirus, for example Dr.Web or Kaspersky.
How to clear RAM if the sensor does not work due to freezing?
Try to perform a forced reboot by holding down the power button and volume down button for 10-15 seconds. This is a hardware reset method that physically clears the RAM by turning off the power to the memory chips.
Does the weather widget on the screen affect the amount of free RAM?
Yes, active. widgets, especially those that are updated in real time (weather, news, exchange rates), take up memory space and use processor time. Removing unused widgets from the desktop can free up from 50 to 150 MB of RAM.
