Mobile e-sports places strict demands on hardware, and poor optimization often becomes the reason for losing a shootout. A split-second delay or a sudden freeze can cost you the “royal crown”. Many players mistakenly believe that third-party boosters or root access is required to improve the picture and smoothness, but this is a dangerous misconception.
In fact, built-in features Android and fine-tuning the game itself allow you to squeeze maximum performance out of the device. The correct configuration of the graphics engine and freeing up RAM can turn even a budget smartphone into a stable gaming platform. Let's take a look at how to achieve the desired 60 or 90 frames per second using only legal methods.
Basic optimization of graphics settings within the game
The first step for any player should be a detailed analysis of the graphics settings menu. Many users automatically set the settings to “Maximum”, without thinking that their processor simply cannot cope with such a load. Graphics engine games require huge resources to render shadows and high-resolution textures, which inevitably leads to drops FPS (frames per second) at critical moments of the battle.
The optimal balance is achieved not by maximum picture quality, but by prioritizing frame rate. You need to go to the section Settings → Graphics and select the “Smooth” profile. This will reduce the detail of objects, but will free up resources GPU for fast rendering of scenes. It is this parameter that is the foundation of stability.
After selecting the “Smooth” profile, access to the “Frame Rate” setting will open. Here you should select the maximum available value: “Ultra” (60 FPS) or “90 FPS” if your device supports high screen resolution. Ignoring this point in favor of beautiful shadows is the main mistake of beginners.
- 🎮 The “Smooth” profile reduces the load on the video core, removing unnecessary visual effects.
- ⚡ The “Frame Rate” setting directly affects the smoothness of aiming and movement.
- 👁️ The “Classic” or “Soft” style often works faster than modes with increased contrast.
Don't forget about the anti-aliasing function. Although it makes the picture nicer, enabling anti-aliasing (Anti-aliasing) creates additional load on the system. In a competitive shooter, the clarity of the enemy is more important than the beauty of the foliage, so it is better to deactivate this option to increase performance.
Releasing RAM before startup
The system Android tends to hold on to background processes in memory for quick re-launch, but in games this plays a cruel joke. Every extra application running in the background bites off precious megabytes RAMthat the game needs for texture caching. Before entering a match, it is critical to perform a complete wipe.
Use the built-in task manager of your smartphone. This is usually done by swiping up from the bottom and holding or pressing the dedicated menu button. Close all applications, including browsers, instant messengers and social networks. Even if they do not actively consume the battery, they take up memory space.
⚠️ Attention: Do not use “boosters” and “cleaners” from the application store. They often work in the background, show ads and can forcefully close system services, which will lead to instability of the phone.
Particular attention should be paid to widgets on the desktop. Live wallpapers, weather widgets and news feeds are constantly updated and consume CPU resources. During the gaming session, it is recommended to switch to static wallpaper and remove unnecessary elements from the main screen.
☑️ Preparing memory before the game
Developer system settings for gaming
For advanced users, the hidden “For Developers” menu provides access to tools that can significantly affect rendering. To activate this section, you need to go to Settings → About phone and quickly click on the build number seven times. After this, a new item will appear in the main menu.
Inside the developer menu, find the section related to hardware acceleration. The “Disable HW overlays” option forces the system to use GPU for compositing images instead of the processor. This can reduce delays when displaying images on the screen, especially on older smartphone models.
It is also worth paying attention to the limit of background processes. Set to "No more than 2 processes" or "No background processes". This ensures that after starting the game, the system will not try to restore the operation of other apps, taking away resources from them.
| Settings in the developer menu | Recommended value | Impact on the game |
|---|---|---|
| Limit of background processes | No background processes | Maximum RAM release |
| Animation windows/transitions | 0.5x or Disabled | Visual interface acceleration |
| Disable HW overlays | Enabled | Reduce CPU load during rendering |
| Strict mode | Disabled | Prevent unnecessary system checks |
Be careful when changing font scale or screen size (DPI) settings. Changing these values too aggressively can make the game interface unreadable or cause the application to crash. Return the default settings immediately after the end of the session.
How to return the default developer settings?
If you are confused about the settings or the game starts to work worse, simply turn off the “For Developers” switch at the very top of the menu. This will instantly reset all changed parameters to factory settings without losing personal data.
Thermal control and throttling prevention
Modern mobile processors are equipped with an overheating protection mechanism called throttling. When the chip temperature reaches a critical point, the system forcibly reduces the clock speed to cool down. For the player, this means a sharp drop FPS and the appearance of jerks precisely at the most intense moment of the battle.
To avoid this, it is necessary to ensure effective heat dissipation. Remove the protective case before playing for long periods of time, as it acts as a thermal insulator, keeping the case cool. Play indoors with good ventilation or under air conditioner/fan flow.
There is a myth that playing while charging always leads to overheating. This is not entirely true, but using cheap power supplies with unstable voltage does cause additional heating of the battery. Use only original cables and adapters that support fast charging technology for your device.
- ❄️ Removing the case improves heat dissipation by 15-20%, which is critical for long matches.
- 🔋 Playing from the network is more stable, but watch the battery temperature (not higher than 40-42°C).
- 🌬️ Directing the air flow from the fan directly to the back cover of the phone effectively reduces throttling.
⚠️ Attention: Never place a working smartphone on soft surfaces (bed, sofa, blanket). This blocks the vents and causes extreme overheating, which can permanently damage the battery.
If you have a smartphone cooler with a Peltier element, use it. Active cooling allows the processor to operate at maximum frequencies much longer than passive ventilation.
Cache clearing and storage management
Filled internal storage is another hidden cause of lags. When free disk space runs out, the system has no place to create temporary files and data buffers. This slows down the reading of textures and loading of locations, causing micro-freezes.
Clear the application cache regularly PUBG Mobile. Don't confuse this with wiping data: caches are temporary files that can be safely deleted, and data contains your settings and maps. Go to Settings → Applications → PUBG Mobile → Storage → Clear cache.
It is also recommended to free up at least 10-15% of the total internal memory of the device. Delete old videos, unnecessary photos, or transfer them to a memory card (if the slot supports applications, although memory cards are often too slow for the game itself).
File system fragmentation can also affect read speed. If your phone doesn't use a modern file system, a periodic factory reset (after creating a backup) can restore the drive to its former speed.
Free disk space acts as a "safety buffer" for the system. The more space, the faster the phone processes temporary data while loading heavy game scenes.
Network optimization and ping
Often players confuse low FPS with high ping. If the picture jerks and characters teleport, the problem may not be with the graphics, but with the stability of the connection. High ping creates the illusion of slow performance because actions are delayed.
Use a 5 GHz Wi-Fi connection instead of the standard 2.4 GHz if your router supports this frequency. The 5 GHz band is less congested by neighboring networks and provides more stable data transmission, which is critical for online shooters.
If you are playing via a mobile network, make sure you have a stable 4G/LTE signal. In areas of poor coverage, the phone constantly switches between towers, causing latency spikes. In such cases, it is better to switch to Wi-Fi or find a place with a better signal.
⚠️ Warning: Avoid using a VPN while playing unless necessary to select a region. Routing traffic through third-party servers almost always increases the ping and adds instability to the connection.
In the settings of the game itself, you can select your preferred server. Choose the one that is geographically closer to you. Even if there are more friends on other servers, the physical distance to the server determines the minimum possible ping.
Why is Wi-Fi better than a mobile network for PUBG?
Mobile networks are affected by the weather, the number of users in the cell, and subscriber movement. Fixed Wi-Fi, especially over a cable from an ISP, provides a fixed route and stable bandwidth, which minimizes packet loss.
Frequently asked questions (FAQ)
Will deleting other games help increase FPS in PUBG?
Removing other games alone will not directly increase FPS if they are not running. However, this will free up storage space, which will improve overall system speed and allow the game cache to work more efficiently. The main thing is to close processes before starting.
Is it safe to use the “Performance” mode in the battery settings?
Yes, this is a standard feature of many Android skins (MIUI, OneUI, etc.). It removes restrictions on processor frequency. The only negative is accelerated battery drain and heating of the device, so keep an eye on the temperature.
Why did the game start to lag after updating Android?
After major system updates, it is often necessary to clear the recovery partition cache or reinstall the game. New OS versions may change memory management methods, and old cache files may conflict with new drivers.
Is it possible to increase FPS on a phone with 4 GB of RAM?
Yes, you can get a stable 40-60 FPS. The key factor here will be to select the minimum graphics settings (“Smooth”) and be sure to clear all background applications before each launch.
Does screen brightness affect performance?
Brightness does not have a direct effect on the processing power of the processor. However, maximum brightness significantly increases the heating of the screen and the entire device, which can quickly provoke throttling of the processor due to the overall high temperature in the case.
