Smooth gameplay in PUBG Mobile is not just a matter of comfort, but a critical advantage in firefights, where every split second determines the outcome of the battle. Even powerful flagship smartphones can begin to slow down over time due to overheating, cache accumulation, or incorrect system settings. Freezes (short-term freezing of the picture) and FPS drops make the game almost impossible at high ranks, especially in Ranked Mode or Tournament.
The reasons for unstable operation can be both software and hardware. Users often blame a “weak phone,” forgetting that aggressive graphics settings or background processes eat up processor resources. In this article, we will look at a comprehensive approach to optimization: from basic settings within the game to deep cleaning of the system and the use of hidden performance profiles.
You will learn how to correctly set the resolution, which graphics parameters really affect smoothness, and which only create the appearance of quality. We will also touch on the topic of thermal throttling - a phenomenon where a device deliberately reduces frequencies to cool, causing sudden lags. Follow the instructions sequentially to identify and eliminate the bottleneck in your system.
Optimizing in-game graphics settings
The first and most obvious step is to adjust the parameters directly in the game menu. Many players mistakenly set the settings to “Maximum”, believing that their phone can handle it, but this leads to overheating and subsequent freezes. The key parameter is the combination of “Graphics” and “Frames per second”. For stable gameplay, priority should always be given to the number of FPS, rather than texture detail.
Go to the section Settings → Graphics and audio. Here you need to find a balance between visual quality and performance. If you experience stuttering, try lowering the graphics profile to Smooth or Balanced. This will reduce the load on the GPU (graphics processing unit), which is critical for maintaining a stable framerate in dynamic scenes.
Pay special attention to the parameter Style. Modes like Vivid or HDR require more resources to post-process the image. Switching to Classic or Soft style will often provide a performance boost without significantly losing enemy visibility. Also disable features such as Shadows and Antialiasing if they are available in your profile - they create unnecessary load.
⚠️ Attention: Do not set the maximum frame rate (for example, 90 or 120 FPS) if your screen does not physically support this Hertz or the processor cannot handle it rendering. This will lead to constant frame tearing and a jerky picture.
After changing the settings, be sure to restart the application. The game must completely rebuild the shaders to fit the new parameters. If freezes persist after this, the problem may lie deeper - in system limitations or background processes.
Use the “Smooth” mode with the highest available FPS (Ultra/Extreme) - this is the “gold standard” for e-sports players, as it minimizes input lag and load on hardware.
Managing RAM and background processes
Lack of random access memory (RAM) is one of the main reasons for sudden freezes. When free memory becomes low, the system begins to actively use the paging file on the internal drive, the speed of which is much lower. This causes those very unpleasant micro-freezes when loading textures or buildings.
Before starting PUBG Mobile it is strongly recommended to close all unnecessary applications. Social networks, instant messengers and browsers can consume hundreds of megabytes of memory even when minimized. Many modern Android shells have a "Memory Cleaner" or "Game Acceleration" function that forcibly closes background tasks.
- 🚀 Close all applications through the multitasking menu before entering the game.
- 📵 Disable synchronization of photos and cloud services during the gaming session.
- 🔋 Activate Do Not Disturb mode so that notifications do not interrupt rendering.
- 🧹 Clear the cache of the launcher and system services through the storage settings.
It is also worth checking whether you have enabled the memory expansion function (Virtual RAM), if it is in the phone settings. Paradoxically, on some devices with fast physical memory, using slow virtual memory through the drive can even worsen the situation, causing additional delays when swapping data.
If you have a device with 4 GB of RAM or less, the situation is critical. In this case, the only solution is to minimize the load: disable widgets on the desktop, remove live wallpapers and use “light” versions of other applications. Every megabyte of free memory counts.
Setting up energy saving and game modes
Modern smartphones are equipped with aggressive power-saving algorithms that can stifle gaming performance in order to save battery power. The system can artificially limit the processor frequency or reduce the screen brightness, which is perceived by the player as lags and freezes.
You need to find the battery settings section and switch the operating mode to the “Performance” or “High Performance” position. In some shells (for example MIUI, OneUI, ColorOS) this is done through a special application “Game Center” or “Game Turbo”. There you can add PUBG Mobile to the list of priority applications.
Inside the game mode the following useful functions are usually available:
- 🎮 Auto-brightness lock to prevent FPS drops when lighting changes.
- 📶 Network priority to reduce ping and packets losses.
- 🚫 Ban on incoming calls and notifications during the match.
- ⚡ Fixation of high processor frequency (CPU Boost).
Pay attention to the temperature of the device. If the phone overheats above 40-45 degrees, a protection mechanism is triggered - throttling. The processor resets its frequencies and the game starts to slow down. In such cases, using an external cooler or playing in a cool room can give a greater effect than any software settings.
⚠️ Attention: The “Maximum Performance” mode significantly increases battery consumption and case heating. Use it only when the charger is connected or in a well-ventilated area.
Disabling power saving is a mandatory step. Without this, the system will constantly “strangle” the processor, causing instability regardless of the graphics settings.
Comparison of settings for different classes of devices
There is no universal recipe for settings, since the architecture of processors Snapdragon, MediaTek and Exynos reacts to the load differently. Below is a table with recommended configurations for devices of different performance levels so you can choose the optimal balance.
| Device class | Graphics | Frame rate (FPS) | Style | Additional. settings |
|---|---|---|---|---|
| Budget (up to 4 GB RAM) | Smooth | High (30-40) | Classic | Shadows and anti-aliasing off |
| Medium (6 GB RAM) | Balanced | Ultra (60) | Bright | Shadows off, anti-aliasing on |
| Flagships (8+ GB RAM) | HDR / Smooth | Extreme (90+) | Any | All effects included. (with temp control.) |
| Tablets | Smooth | Maximum | Classic | Priority of stability |
As can be seen from tables, owners of powerful devices often mistakenly choose HDR graphics, sacrificing smoothness. However, in competitive play, it is more important to see the enemy first than to admire the reflections in the puddles. Therefore, even on top smartphones, many pro players choose the “Smooth” profile for the sake of stable 90 or 120 FPS.
If your device is on the class boundary, try testing both options in the training camp. Launch the bots, shoot and evaluate whether there are any micro-delays when turning the camera sharply. This is the best test before entering a ranked match.
Why is the “Bright” style better for finding enemies?
This style has increased contrast and color saturation, which makes enemy silhouettes more visible against the background of grass and trees, even with low texture detail.
Deep cleaning of the system and game cache
Over time PUBG Mobile accumulates gigabytes of temporary files, resource maps and logs. A clogged storage slows down data reading, which leads to long loading times and freezes when new objects appear on the map. Regular cleaning is a necessary hygiene procedure for mobile gaming.
Go to the smartphone settings, section Applications → PUBG Mobile → Storage. Click the "Clear cache" button. Important: do not click "Clear data" if you do not want to re-download the map resources and management settings. You can safely clear the cache, the game will download the necessary files again the next time you start it.
Also check the total free space on the internal storage. If more than 85-90% of the memory is occupied, the speed of writing and reading files drops significantly. Delete unnecessary videos, photos or transfer them to a memory card (if supported) to free up at least 5-10 GB of space.
For advanced users, it is possible to clean it through the engineering menu or ADB, but this requires caution. Using standard Android tools you can often remove “garbage” left by previous versions of the game. Use your manufacturer's built-in optimization tools, but avoid dubious cleaner applications from the Play Market that themselves consume resources.
☑️ Checklist before the match
Hidden developer and GPU settings
In the “For Developers” menu hidden tools that can radically change the behavior of the system in games. To activate this menu, you need to click on the build number 7 times in the “About phone” section. After the new item appears in the settings, you can begin fine-tuning.
Find the “Keep the screen on” option when charging - this is convenient for long sessions. More important is the section related to animations. Reduce the animation scale of windows, transitions, and animator duration to 0.5x or disable them completely. This will not directly increase FPS in the game, but will make the system interface more responsive, reducing the overall load on the UI thread.
Settings → For developers → Window animation: 0.5xSettings → For developers → Transition animation: 0.5x
Settings → For developers → Animator duration: 0.5x
Also pay attention to the “Background processes” option. Set the limit to "No more than 2 processes" or "No background processes". This will force the system to more aggressively kill applications that you minimized, freeing up resources for PUBG. However, be prepared for the fact that messengers may arrive with a delay.
⚠️ Attention: Changing settings in the developer menu may affect the stability of other applications. If after the changes the phone begins to behave strangely, simply reset the developer settings to factory settings.
Some firmware has the option “GPU processing acceleration” (Force 4x MSAA). Enabling this option can improve picture quality in some games, but in the case of PUBG Mobile it often leads to overheating and a drop in FPS. It is recommended to leave this feature disabled unless you have a flagship device with a powerful cooling system.
If you use third-party launchers, try temporarily switching to the system's standard launcher. Third-party shells often consume extra RAM and processor resources.
Frequently asked questions (FAQ)
Will uninstalling and reinstalling the game help remove freezes?
Yes, this can help if the game files were damaged or the cache was not updated correctly after the patch. A complete reinstallation allows you to download fresh resources and reset all local settings to factory settings, which often solves stability problems.
Does Internet speed affect freezing in graphics?
No, Internet speed affects ping (signal delay) and packet loss, which manifests itself as “teleportation” of characters or delayed shots. Freezes and low FPS are a problem of processor power, video card or overheating of the device, not the network.
Is it possible to overclock a phone for PUBG through third-party applications?
Theoretically, yes, there are applications for overclocking the CPU/GPU, but this is extremely risky. You may experience system instability, overheating, and even physical damage to the battery or chip. It is better to use the built-in game modes from the manufacturer.
Why does the game slow down only in certain places on the map?
This is due to the optimization of the map itself and the number of objects in a specific location (for example, the city of Pechino or a school). In such places, the CPU load increases sharply due to the need to render many buildings and textures at the same time. Lowering the graphics helps smooth out these drawdowns.
Is it worth using “game boosters” from the Play Market?
In most cases, no. Modern versions of Android themselves manage memory very well. Third-party boosters often simply show beautiful cleaning animations, but at the same time consume resources themselves, working in the background. Built-in system tools are more efficient and safer.
