Every owner of a smartphone, especially the budget or mid-range segment, has at least once encountered a situation where their favorite game starts to slow down at the most crucial moment. It would seem that hardware the device should cope, but constant micro-freezes, frame drops and input delays make the process impossible. Often the problem lies not in the lack of processor power, but in the way the operating system distributes resources between running applications.
By default, Android strives to provide multitasking, allocating memory and processor time equally to all active services. However, this approach is detrimental for gaming: the game needs maximum priorityso that the system does not “strangle” it with background updates or heavy services. In this article, we will analyze proven methods that allow you to manually or programmatically force the system to give all resources to the running game process.
We will look at standard shell capabilities, hidden engineering menus and third-party tools. It is important to understand that changing priorities is an interference with the operation of task scheduler the Linux kernel on which Android is based. Correctly setting these parameters can work wonders even on a low-end device.
Before taking radical measures, it is worth noting that different manufacturers implement their own optimization algorithms. Owners of Xiaomi, Samsung or Realme can find ready-made solutions in pre-installed launchers, while on “pure” Android they will have to dig deeper. Let's look at all the available methods, from simple to complex.
Using built-in game modes and Game Turbo
Modern electronics manufacturers have long realized the importance of mobile gaming and have introduced special functions for players into their shells. If you are wondering how to prioritize an Android game, the first thing you should do is look into the settings of the device itself. Most brands, such as Xiaomi, Samsung, OnePlus and Realmehave their own add-ons over the system.
For example, in the MIUI and HyperOS shells there is a function Game Turbo. It not only collects games into one folder, but also forcibly clears RAM before launching the application, and also blocks incoming notifications that can cause lags. In Samsung devices, similar functionality is implemented through the app Game Launcher and the “Performance” mode. Activating these modes automatically assigns the game process a high priority in the system task manager.
⚠️ Attention: In some firmware, the maximum performance mode can significantly increase battery consumption and heat the case. Use it only when FPS stability is important, not autonomy.
However, you should not rely only on automatic algorithms. They often work too aggressively and close background processes you need, such as instant messengers. Therefore, manual configuration via the engineering menu or ADB commands often gives a more predictable result. Built-in utilities are good as a first step in optimization, but full control will require deeper knowledge.
If your smartphone does not have an explicit game mode, this does not mean that the system cannot speed up applications. It's just that these functions may be hidden or require activation through third-party launchers. Owners of “stock” Android, for example, on Motorola or Nokia smartphones, will have to use more universal methods, which will be discussed below.
Configuring developer options for process priority
For finer control over the system, you need to activate the developer menu. This is a hidden settings section that gives access to controls background process limit and animations. To get there, you need to quickly tap the build number seven times in the About Phone section. After the corresponding notification appears, a new item will appear in the settings menu.
Inside the “For Developers” section, we are interested in the “Background process limit” parameter. It is not installed by default, which allows the system to keep dozens of applications in memory. Changing this value to "No more than 2 processes" or "No background processes" will force Android to release resources for active gaming. This is the most direct way to increase the priority of the current application by closing the others.
Also in this section it is worth paying attention to the animation speed. Reducing the window scale, transition and animation duration to 0.5x or completely disabling visually speeds up the interface and reduces the load on the graphics accelerator. While this does not directly change the process priority, it frees up CPU cycles for game rendering.
- 🚀 Window animation: Set to 0.5x or Disabled for instant UI response.
- 🧹 Do not save activity: Dangerous option that kills the background process immediately upon exit, use with caution.
- ⚙️ Background limit: strictly limiting the number of applications running in the background.
- 📡 Wi-Fi aggregation: sometimes helps stabilize ping by combining channels (not available on all chipsets).
This ensures that new parameters are applied to the system core correctly. Without a reboot, some services may continue to work in the old mode, ignoring your changes.
☑️ Developer setup checklist
Using ADB commands to change Nice values
For users who do not are afraid of the command line, there is the most effective method - using Android Debug Bridge (ADB). This tool allows you to send commands directly to the system, bypassing the GUI. With its help you can change the “Nice value” of the process. On Linux-like systems, such as Android, process priority is determined by a number from -20 (highest priority) to 19 (lowest).
By default, games run at normal priority. Using ADB, you can forcefully change the priority of the game process, giving it priority over system services. To do this, you will need a computer, a USB cable and ADB drivers installed. After connecting the smartphone and debugging via USB, a series of commands are executed.
adb shellsu
renice -n -10 -p $(pidof com.imya.igry)
In the example given, the command renice changes the priority of the process with the name of the package com.imya.igry to -10. The lower the number (in the negative direction), the higher the priority. However, you should be careful: setting the priority too high (for example, -20) for a heavy game may cause the system to no longer have time to process the touch screen or sound, since all resources will be spent on graphics.
⚠️ Attention: To execute the command
su(superuser) root access is required on most devices. Without them, the command will return an access error. Also, changing system priorities can lead to unstable operation of the OS.
An alternative to manually editing Nice values is to use a utility CPU Tweak or analogues that require root access. They allow you to set CPU Governor profiles, switching the processor to “Performance” mode only when running certain applications. This is a softer and safer way than directly manipulating process priorities through ADB.
What is PID and how to find it?
PID (Process Identifier) is a unique number that the system assigns to each running process. To find the PID of a non-rooted game, you can use the command “adb shell ps | grep package_name". The command output will contain a column with the process number, which can be used to control priority.
Third-party booster applications and their real effectiveness
There are thousands of applications in the Google Play Store that promise to speed up games. They have names like "Game Booster", "Optimizer" or "Cleaner". The way they work is usually to automatically close background applications and clear the cache before launching the game. Some of them, such as Game Booster 4x Faster or GFX Tool, actually know how to change rendering parameters.
However, it is worth understanding the mechanism of their work. On non-Rooted devices, such applications cannot actually change the priority of the kernel process. They only simulate vigorous activity by closing other applications through standard Android APIs, which the system can do itself. Only those boosters that require root access or work in conjunction with a PC have a real effect.
Applications for changing screen resolution and DPI stand out. Reducing the rendering resolution (for example, from 1080p to 720p) through the GFX Tool significantly reduces the load on the GPU, which is equivalent to increasing the priority of graphics calculations. This often gives a greater increase in FPS than any manipulation of processor time.
| Application | Root required | Operation principle | Efficiency |
|---|---|---|---|
| Game Booster 4x Faster | No (basic) | Clearing RAM, changing DPI | Average |
| GFX Tool for PUBG | No | Decreased quality graphics | High (for FPS) |
| CPU Tweak | Yes | Overclocking and core priorities | Very high |
| Greenify | No (basic) | Hibernation of background processes | High (for battery) |
Using third-party software carries its own risks. Aggressive "cleaners" can constantly kill system services, which will ultimately lead to even greater load on the processor, since the system will have to constantly restart the killed processes. Use such tools wisely, preferring those that allow you to customize exclusion lists.
Before installing any booster, check its permissions. If a simple optimizer requires access to contacts, microphone and geolocation, it is better to remove it immediately. This is a sign of spyware, not a useful utility.
Optimizing the network to reduce ping in games
Often, by “brakes”, users do not mean low FPS, but high ping or packet loss. In online games, priority is important not only for the processor, but also for network traffic. Android by default does not separate traffic into foreground and background, so downloading updates to Google Play may lag the game.
To prioritize the game in terms of network, you can use the “Traffic Saver” feature for all applications except the game. Go to Settings → Network and Internet → Saving traffic. Enable this mode and add your game to the exclusion list. This will prevent other applications from actively using the Internet in the background, leaving the channel free for play.
It is also worth considering using DNS with low latency. Changing DNS to Google DNS (8.8.8.8) or Cloudflare (1.1.1.1) can speed up the server response. This can be done in the connection settings: Settings → Connection and general settings → Private DNS. Enter the address there dns.google or 1dot1dot1dot1.cloudflare-dns.com.
- 🌐 5 GHz Wi-Fi: Always connect to a 5 GHz network if your router supports it. It is less busy and provides lower ping than 2.4 GHz.
- 📶 mobile data: In games like PUBG or CoD Mobile, 4G/5G is often more stable than home Wi-Fi due to better routing of operators.
- 🚫 Background synchronization: Disable synchronization of photos and cloud services while playing.
There are also router applications for Android that work without root, which can block network access for selected applications. This ensures that no background updates will eat up your channel. However, the most reliable way is to physically disconnect Wi-Fi from other devices in the house during tournament play.
⚠️ Warning: Network settings are highly dependent on your ISP and router model. What helps one user may not work for another. Always test the ping through the game's built-in tool before starting a match.
Radical methods: root access and custom kernels
If you are willing to take the risk and lose the guarantee, obtaining superuser rights (Root) opens the door to optimization. With root access, you can install custom kernels (Custom Kernels), which have their own task schedulers tailored for gaming. Cores like KonaBess (for Snapdragon) allow you to overclock the GPU and change priorities at the driver level.
One of the most powerful tools is the module Magisk. There are modules that automatically apply optimization scripts when the game starts. They change processor frequencies, control thermal control (disabling throttling, which is dangerous for the battery, but gives stable FPS) and redistribute thread priorities.
You can also use the application Kernel Adiutor or Franco Kernel Managerwith root access. In them you can manually set the CPU Governor to Performance or Interactive with aggressive settings. This forces the processor to always maintain maximum frequencies, ignoring power saving. The priority of the game in such an environment becomes absolute.
root access give complete control over priorities, but carry the risk of “bricking” the device. Beginner users should limit themselves to standard game modes and developer settings.
Do not forget about thermal throttling. Even if you set the maximum priority, when the temperature rises above 45-50 degrees, the processor will reset the frequencies, and priorities will no longer matter. Therefore, during deep optimization via Root, you often have to intervene in the cooling system, deleting thermal control files (which is highly not recommended without understanding the physics of the process).
Frequently asked questions (FAQ)
Will clearing the cache help increase the priority of the game?
Clearing itself cache does not change the priority of the process in the kernel. However, it frees up storage space, which can indirectly improve I/O performance if memory is more than 90% full. Other methods are needed to increase CPU and RAM priority.
Is it safe to use applications to change Nice values?
Changing Nice values is safe as long as you do not set critical system processes to low priority. If you accidentally set the input (Touch) or display service to a low priority, your phone may stop responding to touches. Always know which process you are modifying.
Why does the game slow down even with maximum priority?
Priority is the task queue. If the hardware does not physically support graphics (few GPU cores, old architecture), then no priority will add frames. Also, the reason may be overheating (throttling) or poor optimization of the game itself for your version of Android.
Do you need to close applications manually before playing?
In modern versions of Android (10 and higher), the system itself effectively manages memory. Forcing applications to close using the ellipsis often wastes battery life as applications are launched again. It is better to use the game mode or limit background processes in the developer settings.
Could a virus be the reason for the low priority of the game?
Viruses and miners can take up to 100% of the processor resources in the background, which is why the game gets nothing. If nothing helps, check the device with an antivirus or analyze the list of processes in the developer menu for unknown energy consumers.
