Playing Mobile Legends: Bang Bang at a higher refresh rate changes how fast team fights unfold. When you push your device to run higher frame rates, animations feel cleaner, skill shots land with better precision, and tracking fast-moving heroes becomes much easier. However, older operating systems like Android 9 (Pie) often run into restrictions because developers cap high refresh rates natively for unsupported hardware profiles.
If you're trying to bypass these limits on an older phone or custom setup, you need to understand the hardware bottlenecks, system limitations, and configuration options available. Let's look at what it takes to configure your device correctly without risking your account safety or frying your phone's processor.
Understanding Android 9 and High Refresh Rate Limits
Android 9 Pie handles display drivers and surface composition differently than modern Android versions. Back when Android 9 was standard, 120Hz panels were rare and mostly limited to specialized gaming phones like the early ASUS ROG series. Because of this, Moonton's game client often hides the "Ultra" frame rate option on devices running older OS versions or older chipsets, even if the physical screen supports high refresh rates.
The main hurdles you'll face on Android 9 include:
- Native Application Capping: The game code checks your device model and OS version against an internal whitelist. If Android 9 is detected, the game defaults back to 60 FPS to maintain stability.
- Thermal Throttling: Older processors running Android 9 lack modern thermal management algorithms. Pushing 120 frames per second forces the CPU and GPU to work twice as hard, leading to rapid heat buildup.
- API Restrictions: Older graphics Application Programming Interfaces (APIs) don't optimize resource allocation as efficiently as Vulkan or modern OpenGL ES implementations, making frame drops common during intense team clashes.
Essential Prerequisites Before Tweaking Settings
Before attempting any configuration changes, verify that your hardware can actually handle the processing load. Trying to force high frame rates on weak hardware results in severe stuttering rather than a smooth experience.
- Verify Display Hardware: Your phone's physical screen must support a 120Hz refresh rate. If your panel is locked at 60Hz natively, software adjustments won't change the physical capabilities of the display.
- Check Thermal Performance: Ensure your phone isn't prone to overheating. Clean out background applications to free up RAM—aim for at least 4GB to 6GB of available memory.
- Inspect Game Version: Keep your application updated to the latest available patch from official channels like the Google Play Store to ensure compatibility with standard asset files.
Configuring Your System for Maximum Performance
If your device manufacturer included a native high-refresh toggle or a gaming mode dashboard, use it to prioritize game threads.
Open your device settings and look for a display or refresh rate menu. Set the system refresh rate to its highest setting (usually 120Hz). Next, open your phone's native performance booster—such as Xiaomi's Game Turbo or equivalent utilities—and add Mobile Legends to the priority list. This tells the kernel to allocate more CPU cycles to the game process.
Inside the game settings, navigate to the graphics panel:
- Lower your graphics quality to Smooth or Medium. High textures combined with 120 FPS will overwhelm an Android 9 chipset.
- Turn off resource-heavy extras like high-definition outlines and dynamic shadows to reduce GPU strain.
- Check if the Ultra frame rate option becomes available once your system performance mode is active.

Common Mistakes to Avoid
Many players trying to boost performance on older operating systems make critical errors that ruin their gameplay or harm their devices.
- Using Unverified Third-Party APKs: Downloading modified game clients from random file-sharing sites often exposes your device to malware or results in an immediate account suspension from Moonton's security systems. Stick to official application binaries.
- Ignoring Thermal Limits: Running an unoptimized phone at maximum frame rates until it shuts down from thermal overload degrades the battery lifespan rapidly.
- Expecting Stable Frequencies on Low-End Chips: If your processor is an older mid-range chip, forcing high frame rates causes heavy frame pacing issues. A stable 60 FPS looks and feels much better than a fluctuating 40-to-110 FPS roller coaster.
Frequently Asked Questions
Can I get banned for modifying game configuration files on Android 9?
Yes. Modifying system files, resource directories, or using modified game patches violates the terms of service. Moonton employs automated detection tools that flag altered packages, which can lead to temporary or permanent bans.
Why is the Ultra frame rate option missing even though my screen is 120Hz?
The game developer must whitelist your specific phone model and software combination to enable the Ultra setting officially. If your device runs Android 9, developers often omit support because newer operating systems handle the necessary graphics APIs more reliably.
Does 120 FPS drain my battery faster on older phones?
Significantly faster. Rendering double the frames per second requires the processor and display panel to draw much more electrical current, which drains the battery and generates high heat. Keep a charger nearby or limit long gaming sessions.
How can I check if my game is actually running above 60 FPS?
You can use third-party hardware monitor overlays or developer options built into your device to display real-time frame rates on screen. This helps you confirm whether your performance tweaks are making a genuine difference.
