Mobile shooter PUBG Mobile remains one of the most resource-demanding projects on the Android platform. Even owners of flagship devices often experience frame drops, overheating and unstable ping, which critically affects the outcome of the “battle royale”. The problem lies not only in the hardware, but also in the incorrect default settings that game developers set for a wide range of devices.
Deep system optimization allows you to turn an average smartphone into an eSports tool. This is a complex process that includes not only changing parameters inside the game client, but also fine-tuning the operating system, managing background processes and monitoring temperature conditions. The correct approach to setting graphics rendering and allocation of processor resources can give a performance increase of up to 30% without the use of third-party software.
In this guide we will analyze all the stages: from basic preparation of the device to advanced overclocking methods through the engineering menu. You will learn which settings really work and which are myths. Our goal is to provide you with maximum picture smoothness and minimal input lag so that every shot is registered by the server instantly.
Basic device preparation and resource cleaning
Before getting into complex graphics settings, you need to free up the RAM and processing power of the processor. Modern versions of Android aggressively manage background tasks, but games like PUBG can still conflict with other services. First of all, go to Settings → Applications and force stop all unnecessary apps, especially social networks and instant messengers that constantly update content in the background.
Freeing up space on the internal storage also plays a key role. When the memory is more than 85% full, the cache writing speed drops, which causes micro-freezes when loading building and landscape textures. It is recommended to delete old screenshots, videos and cache of other applications. Use the built-in cleaning utility or third-party managers, but avoid aggressive "boosters" that themselves consume resources.
An important step is to disable system animations. They are beautiful in everyday use, but in the game they create unnecessary load on the GPU. To do this, activate developer mode by clicking seven times on the build number in the About phonesection, and then find the items "Window Animation", "Transition Animation" and "Animation Duration". Set the value 0.5x or disable them completely.
- 🚀 Close all background applications through the task manager before starting the game.
- 🗑️ Free up at least 3-5 GB of free space on the internal storage.
- 🔋 Turn on Do Not Disturb mode to prevent notifications from interrupting the rendering process.
⚠️ Attention: Do not use third-party applications like "Game Boosters" from untrusted sources. Often they simply kill processes that the system itself will launch in a minute, creating additional load on the processor and draining the battery faster.
☑️ Preparing your smartphone for the match
Optimal graphics settings inside PUBG Mobile
The most obvious, but often misunderstood stage is the settings inside the game client itself. Many players mistakenly believe that setting the graphics to "Maximum" will give an advantage. In reality, competitive gaming prioritizes frames per second (FPS) rather than grass or shadow detail. High graphics create unnecessary particles and effects that can interfere with the view of enemies.
The ideal configuration for most devices looks like this: the graphics are set to "Smooth" (Smooth), and the frame rate is set to the maximum available value (60, 90 or Extreme). The "Smooth" mode removes unnecessary textures, making enemy models more contrasting against the background of the environment. This is not just saving resources, it is a tactical advantage that allows you to quickly notice movement in the bushes.
Color style also affects the perception of the picture. "Bright" (Colorful) mode increases saturation, making enemies more visible, especially at dusk or in poorly lit rooms. While the "Realistic" mode can merge the enemy's shape with shadows. Disable shadows and anti-aliasing if your smartphone is prone to overheating - these parameters eat up to 20% of the GPU power.
| Parameter | Recommended value | Impact on FPS |
|---|---|---|
| Graphics | Smooth | Maximum gain |
| Frames per second | Extreme / 90 FPS | Critical important |
| Style | Colorful | Does not affect, improves visibility |
| Shadows | Disabled | Average gain |
If your phone supports 90 Hz or 120 Hz, but the game does not have such an option, do not rush to download the configs. First, check if you have the power saving mode turned on in your system - it often blocks the high refresh rate of the screen in games.
Android system settings for games
The Android operating system has hidden capabilities for optimizing games that not everyone knows about. In the developer menu you can find the option 4x MSAA (anti-aliasing). Enabling this item forces the GPU to process graphics more efficiently, but in the case of PUBG Mobile this often leads to the opposite effect - a drop in FPS and overheating. For this game, it is better to leave this option disabled, since the game engine itself controls the anti-aliasing.
Another important aspect is controlling the processor frequency. Some manufacturers (Xiaomi, ASUS, OnePlus) introduce their own game modes (Game Turbo, Game Genie). In these utilities, you need to set the performance priority to maximum. This prevents the system from reducing the processor clock speed even when heated, which prevents throttling (frequency reset) in the most critical moments of a firefight.
It is also worth paying attention to the screen resolution. If you have a smartphone with a resolution higher than FullHD+ (for example, 2K or 4K), it makes sense to reduce it to 1080pin the system settings. Rendering a game in native high resolution creates a colossal load on the video accelerator, which the eye on a 6-inch screen may not even notice, and the battery will run out twice as fast.
⚠️ Attention: Enabling the "Keep the screen on" option in the developer settings during the game can lead to matrix burns (pixel burnout), since static interface elements (sight, map) will burn in one place for hours.
Unlocking 90 FPS and working with configuration files
Many users want to unlock 90 or 120 frames per second on devices that are not officially supported by the game developers. This is achieved by editing configuration files or using special scripts. However, this method carries risks: for modifying client files, you can get a temporary account block (10 years) from the game's anti-cheat.
If you still decide, the process usually involves replacing the file Active.sav or UserCustom.ini in the game directory. These files contain parameters that tell the server what FPS is available on your device. Before replacing, be sure to back up your original files. After changing file access rights (chmod 644), the game can gain access to hidden graphics settings.
A safer alternative method is to use third-party launchers or utilities like GLTools (requires root access), which emulate a more powerful smartphone model. The game “thinks” it is running on a flagship and opens at 90 FPS settings. But remember that emulation also consumes resources, and the actual gain may be less than expected.
Risks of using configs
Using third-party configuration files violates Tencent's user agreement. The anti-cheat system of the game periodically scans the integrity of files. If the hash sum of the file does not match the reference sum, the account is included in the ban list. Most often, this is a 10-year ban with the wording “unauthorized software.”
Reducing input lag and optimizing the network
High FPS is useless if there is a delay between pressing the fire button and shooting on the server. This problem, known as Input Lag, is often caused by software bugs. Disable any screen overlays: blue light filters, screen recording, productivity widgets. Each extra layer of the composition increases the frame rendering delay.
Network optimization is no less important. Use low latency DNS servers such as Cloudflare (1.1.1.1) or Google (8.8.8.8). This can be done in the private DNS settings on Android 9 and above. Also try to play via Wi-Fi 5 GHz, not 2.4 GHz, since the latter range is heavily loaded with neighboring routers and Bluetooth devices, which causes packet loss (packet loss).
In the game, enable the display of ping and packet loss in the settings. If you see red numbers or a packet loss icon, the problem is not with your phone, but with the communication channel or server overload. In this case, changing the connection region or using a gaming VPN (for example, GearUP Booster) can stabilize the connection, although it will add a few milliseconds to the ping.
- 📶 Use the 5 GHz Wi-Fi band to minimize signal interference.
- 🌐 Set a fast DNS in the network settings to speed up the response servers.
- 📵 Turn off Bluetooth if you are not using wireless headphones (it operates in the same frequency range as Wi-Fi 2.4 Hz).
⚠️ Attention: Interfaces of mobile operators and router settings are constantly updated. If you cannot find the DNS settings or Wi-Fi range switching, check the current instructions for your router model or tariff plan in your provider's personal account.
Stable ping is more important than high FPS. It is better to play at 40 frames with a 20 ms ping than at 90 frames with constant lags and character teleportations.
Temperature control and preventing throttling
Throttling is the main enemy of stable gameplay on Android. When the processor reaches a certain temperature (usually 45-50°C), the system artificially lowers its frequency to prevent damage. At this point, FPS can drop from 60 to 20 in a couple of seconds. The solution to this problem lies in the field of physical cooling.
Using an external cooler (fan cooler) with a Peltier element is the most effective solution. Such devices are mounted on the back cover of the smartphone and actively remove heat, allowing the processor to operate at maximum frequencies for hours. If there is no cooler, remove the case while playing. Thick silicone or leather cases work like a thermos, preventing heat from dissipating.
Also reduce the screen brightness. The display is one of the main sources of heat in a smartphone. Reducing the brightness to 50-60% will not only reduce heating, but also save battery power. Indoors, this is quite enough for a comfortable game, and the load on the power system will be significantly reduced.
Recommended temperature conditions:Ideal: 30-35°C
Acceptable: 35-40°C
Critical (start of throttling): 42°C+
Dangerous: 45°C+
Try playing by connecting your phone to a charger that supports fast charging, but only if you have active cooling. Otherwise, the combination of “charging + playing” is guaranteed to overheat the battery and accelerate its degradation.
Frequently asked questions (FAQ)
Will clearing the game cache before each match help increase FPS?
No, that's a myth. Clearing the cache before a game will force the processor to reload and compile shaders and textures, which will lead to the opposite effect - lag at the beginning of the match. The cache needs to be cleared only if the game starts to work incorrectly or after major updates.
Is it true that the "Flight" mode improves ping?
Partially. Airplane mode turns off all radios, including cellular communications. If you're playing on Wi-Fi, turning on Airplane mode and then manually turning on Wi-Fi only can eliminate background cell tower scans, stabilizing the connection a little, but it won't change the ping dramatically.
Is it possible to play PUBG Mobile on a smartphone with 3 GB of RAM?
Technically it is possible, but the experience will be painful. The game will be constantly unloaded from memory when minimized, and textures will be loaded with a delay. For comfortable gaming in 2026-2026, 4-6 GB of RAM is considered the minimum standard.
Is it worth updating GPU drivers on Android?
On Android there is no way to separately update video card drivers, as on a PC. They are built into the system firmware. The only way to get a new driver is to update your Android version or wait for an update from the smartphone manufacturer.
