Mobile gaming has reached incredible heights, but even powerful smartphones sometimes cannot cope with modern heavy projects, causing annoying stutters. A low frame rate turns a fast-paced shooter or racing game into a slideshow, depriving you of the advantage in reaction and pleasure from the process. Framerate (FPS) directly affects the smoothness of the picture and the responsiveness of controls, so increasing it is a top priority for any player.
Fortunately, the operating The system Android provides ample opportunities for optimizing performance without the need to obtain root access. There are many ways, from simply clearing the cache to changing hidden system parameters, which can significantly change the situation. In this article, we will look at proven methods that will help you get the most out of your device.
Before taking radical measures, you need to understand that each smartphone has its own physical limit, determined hardware. Software tweaks will not turn a budget phone into a flagship, but will help stabilize the system and remove unnecessary loads. Willingness to experiment with settings is the first step to defeating lags.
Basic system optimization and freeing up resources
The simplest and most often ignored step is freeing up RAM and CPU time from background tasks. Many users do not realize that running instant messengers, social networks and geolocation services consume a significant portion of resources RAM. Before starting a heavy game, it is recommended to close all third-party applications through the multitasking menu.
Particular attention should be paid to startup apps. Some utilities register themselves in the start-up and always hang in your memory, even if you don’t use them. Go to application settings and force stop those services that are not required for the system to function. This will free up cycles CPU for processing game graphics.
It is also critical to monitor the free space in the internal memory. When the storage is more than 90% full, the speed of reading and writing data drops, which causes freezes when loading textures. Delete unnecessary videos, old installation files APK and the cache of heavy applications.
- 🗑️ Clear the cache of all unused applications through the storage settings.
- 🚫 Disable widgets on the desktop that update in real time.
- 📴 Temporarily disable synchronization of Google accounts and cloud services.
☑️ Checklist before the game
⚠️ Attention: Do not use so-called “Task Killers” from third-party stores. They often work more aggressively than standard Android tools, forcibly terminating system processes, which can lead to unstable operation of the phone and even a reboot.
Developer settings to speed up rendering
In the Android system menu there is a hidden “For Developers” section, which contains tools for fine-tuning the graphics pipeline. To activate it, you need to click on the build number several times in the “About phone” section. This is where the keys to improving performance are found. GPU.
Find the “Animation Scale” item and set all three values (animation of windows, transitions, duration) to “No animation” or “0.5x”. This will not directly increase FPS in the game itself, but will make the system interface more responsive, saving processor resources on rendering transitions between menus.
A more aggressive method is to enable the “Force GPU rendering” option. This feature forces the system to use the graphics chip to render 2D interface elements, relieving the CPU load. However, on modern devices with powerful SoC this option may already be enabled by default or absent.
Risk of using developer settings
Some experimental features, such as disabling HW overlays or changing GPU drivers, may cause a black screen or system crash. If after changing the settings the phone behaves strangely, just reboot it - most temporary settings will be reset, or go to the developer menu and turn off the main switch.
Another useful setting is limiting background processes. In the same menu, find the item “Background process limit” and set the value to “No more than 2 processes”. This ensures that the system will allocate the maximum available RAM specifically for the active gaming application.
Managing graphics and resolution within games
Often the reason for low FPS lies not in the weakness of the phone, but in the high settings of the game itself. By default, developers can set high graphics settings that your device simply cannot handle. Go to the settings of a specific game and find the “Graphics” or “Video” section.
First of all, lower the rendering resolution. If the game allows you to choose between HD, Full HD and 2K, select the lowest available value. Reducing the resolution is the most effective way to increase frames per secondas the video chip needs to process fewer pixels. The visual difference on a small smartphone screen is often unnoticeable, and the increase in smoothness will be enormous.
Also turn off or minimize the following effects:
- 🌫️ Real-time shadows and lighting (Shadow Quality).
- 💧 Reflections and anti-aliasing.
- 🌿 Vegetation detail and drawing distance (Draw Distance).
Many modern games have a built-in “High frame rate” or “90/120 FPS” mode. Make sure it is activated, but remember: if the phone is not stable at these values, it is better to select “Stable FPS” or “30/60 FPS” to avoid micro-lags.
| Graphics settings | Impact on FPS | Impact on visuals | Recommendation |
|---|---|---|---|
| Resolution | Critical | High | Reduce to 720p |
| Shadows | Average | Average | Off or Min |
| Smoothing | High | Low | Disable |
| Textures | Low (depending on RAM) | High | Leave Medium |
If the game does not have detailed graphics settings, look in Internet configuration file (config.ini or similar) for your phone model. Sometimes manual editing of this file allows you to disable effects hidden from the user in the menu.
Thermal control and throttling prevention
One of the main reasons for FPS drops during long gaming sessions is throttling. When the processor and graphics card reach critical temperatures, the system automatically reduces their frequencies to prevent damage. This leads to a sharp drop performance after 15-20 minutes of play.
To combat overheating, remove the protective case while playing. Thick silicone or leather cases act as a thermal insulator, preventing heat from dissipating through the case. Play in a cool room and avoid direct sunlight on the screen.
There are special accessories - coolers for smartphones. These are small fans or Peltier elements that are attached to the back cover of the phone. Using active cooling can maintain maximum processor frequencies 20-30% longer than with passive cooling. This is especially true for console emulators and heavy shooters.
⚠️ Warning: Never place a hot smartphone in the refrigerator or freezer for quick cooling. A sudden temperature change will cause condensation inside the case, which is guaranteed to lead to a short circuit and damage to the device.
It is also worth turning off charging during the game. The process of charging the battery itself generates heat, which, combined with the heat from the game, creates a double thermal load. If you need to play for a long time, it is better to use an external battery (Power Bank), which can be taken outside the phone case.
Third-party utilities and Game Boosters
There are many booster applications on the market, such as Game Booster 4x Faster, GFX Tool or proprietary utilities from manufacturers (Game Turbo from Xiaomi, Game Launcher from Samsung). These apps create a profile for the game, clear memory and sometimes change the priorities of processes in the system.
GFX Tool is a separate class of apps popular among PUBG Mobile and Call of Duty players. They allow you to unlock hidden graphics settings that are not available in the regular game menu. Using them, you can set the resolution to 960x540 or enable 90 FPS mode on supported devices.
However, be careful: using third-party utilities that modify game files may be considered cheating by the anti-cheat system. This threatens temporary or permanent account blocking. Use such tools only for offline games or projects with a loyal policy.
Proprietary game modes from smartphone manufacturers are usually safe. They work at the system level, disabling notifications, blocking navigation buttons, and directing network resources exclusively to the game. Check whether this mode is activated in your phone's settings.
Third-party boosters work on the principle of “clearing memory before starting”. They do not magically overclock the hardware, but only create favorable conditions, removing competition for resources from other applications.
Radical methods: Overclocking and custom cores
For advanced users who are willing to risk the warranty, there is the possibility of overclocking (overclocking) the processor and video card. This requires root access special applications like Kernel Adiutor or Franco Kernel Manager. By increasing the CPU and GPU frequencies, you can achieve a significant increase in FPS.
The overclocking process is individual for each crystal. It is necessary to increase the frequency in small steps and test stability in benchmarks. If the phone starts to reboot or artifacts in games, the frequency needs to be reduced. Also, overclocking inevitably leads to an increase in power consumption and temperatures.
An alternative to manual overclocking is to install a custom kernel. Enthusiasts are creating modified system cores that have more aggressive performance profiles and better power management than stock solutions from vendors.
Example command to check current frequencies (via terminal with root):
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
Remember that any modification of system software carries risks. An error in voltage settings can physically burn the processor. If you are not sure of your actions, it is better to limit yourself to the software optimization described in the previous sections.
⚠️ Attention: Overclocking and installing custom kernels will void the manufacturer's warranty. In addition, banking applications and games with anti-cheat protection (SafeNet) may stop working on a rooted device without additional manipulations with disguise.
Frequently asked questions (FAQ)
Will resetting to factory settings help increase FPS?
Yes, a full reset (Factory Reset) removes all accumulated system garbage, erroneous configs and background processes that could slow down the system over time. This often returns the phone to performance close to new out of the box. However, before doing this, be sure to back up your important data.
Why did games start to slow down after updating Android?
New versions of the operating system often require more resources to operate their services. Additionally, the update may reset GPU driver optimization. Try clearing the cache of the Dalvik/ART partition (Recovery Mode is required) or wait for an update of the game itself, which will optimize it for the new OS.
Does full memory affect FPS?
Yes, directly. If the internal memory is full to capacity, the system has no place to create swap files and temporary buffers. This leads to the processor being idle waiting for data from the drive, causing freezes. It is recommended to keep at least 15-20% of the total memory free.
Is it possible to increase FPS on an old phone?
Miracles do not happen: if the graphics chip is architecturally outdated, it will not be able to calculate the complex shaders of new games. However, reducing the resolution to a minimum and disabling all effects can make the game playable, albeit with a simplified picture. In some cases, installing lightweight versions of games (Lite) helps.
Is it safe to use the GFX Tool for PUBG?
Using third-party tools that modify game files always carries the risk of being blocked. PUBG Mobile developers periodically ban accounts for using unofficial configs. It's safer to use the built-in game settings or proprietary game modes of your smartphone.
