How many FPS in PUBG Mobile on Xiaomi Redmi Note 9S: tests, settings and optimization secrets

Xiaomi Redmi Note 9S is still a popular choice among gamers, despite the release of newer models. This smartphone based on Qualcomm Snapdragon 720G promises stable performance in PUBG Mobile, but how many frames per second (FPS) it really produces? In this article, we will understand what you can expect at different graphics settings, how to measure them correctly and what to do if the game begins to slow down.

Many users are faced with conflicting information: some claim that the Redmi Note 9S easily pulls 60 FPS at high settings, others complain about drawdowns of up to 30-40 frames in battles. Let's figure out what the real performance depends on, what factors affect FPS and how to maximize the potential of your device. Spoiler: everything is not as clear as it seems!

Specifications of Redmi Note 9S and their impact on FPS in PUBG Mobile

Before we talk about specific FPS figures, let’s understand what exactly in Xiaomi Redmi Note 9S is responsible for performance in games.

• 🔥 Processor: Qualcomm Snapdragon 720G (8 cores, up to 2.3GHz) with the Adreno 618 graphics accelerator.It's a mid-range chipset optimized for gaming, but not a flagship.
• 🧠 RAM: 4 or 6 GB LPDDR4X. More than that. RAM, less texture loading and less friezes.
• 📱 Screen: 6.67-inch IPS LCD permittingly 2400×1080 and frequency of renewal 60 Hz. That means over and above. 60 FPS You won’t physically see it, the screen doesn’t support a higher frequency.
• 🔋 Cooling: Passive (no liquid system) During long sessions, the processor may trott (reduce frequency), which will affect the processor. FPS.

It's important to understand that PUBG Mobile is not just about graphics, it's about physics, adversary AI, networking. The Snapdragon 720G handles that load, but not without compromise. For example, at maximum settings (HDR + Ultra), the CPU and GPU are at their limit, leading to overheating and FPS drawdowns. But on Smooth + Extreme, the picture is quite different.

Another nuance is the game version. PUBG Mobile and PUBG Mobile Lite require different resources. On the Redmi Note 9S, the first version will work more stable, but with limited settings, and the second can produce higher FPS due to simplified graphics.

Real FPS tests on Redmi Note 9S: numbers and observations

We tested PUBG Mobile on the Xiaomi Redmi Note 9S (6/128GB) with the latest MIUI and game updates.

As you can see from the table, the most stable FPS is achieved on the Smooth + Extreme settings, and the difference between Balanced and HDR is huge: the latter not only “sits” the frames, but also turns the smartphone into a “hooker”. Interestingly, PUBG Mobile Lite even at the average FPS settings is higher than in the main version on Balanced.

Important: The tests were conducted in Erangel (classic mode) with full lobby (100 Players in Arcade or Training modes FPS maybe higher 5-10 It's a little bit less load on the processor, and it's also a little bit more impactful. MIUI: On custom firmware (e.g. Pixel Experience) results may differ.

Why FPS is Falling: 5 Top Causes and How to Remove It

Even at optimal settings, the Redmi Note 9S can start to slow down.

• 🔥 Overheating of the processor: During a long game (more than 30 minutes) Snapdragon 720G Solution: Play with Game Turbo on. MIUI or use a cooling stand.
• 📱 Background processes: Messengers, social networks and even MIUI-Services can steal resources. Solution: clear before playing RAM through settings → Annexes → Cleanup.
• 🔋 Low battery charge: At levels below 20%, the system automatically limits performance.Solution: play from charging or keep charge above 30%.
• 🌐 Poor internet connection: High ping and batch losses make the game "hang" Solution: play over 5GHz Wi-Fi or 4G well-covered.
• 🔄 An outdated version of the game or MIUI: New updates often optimize performance.Solution: Check for updates to Google Play and Settings → The phone.

So, you should pay special attention to the power saving settings, and MIUI can default to Battery mode, which limits performance, to turn it off:

1. Go to Settings → Battery and performance.
2. Choose Performance (or High Performance).
3. Add PUBG Mobile to the list of apps without restrictions.

💡

If the game started to lag after the update, try clearing the PUBG Mobile cache in the app's settings.This often resolves FPS drawdown issues.

Comparison with competitors: how the Redmi Note 9S is held against the background of other smartphones

To see how good the Redmi Note 9S is for PUBG Mobile, compare it to other popular smartphones in the same price segment (2026):

The Redmi Note 9S is doing well: it beats the Galaxy M31 and is almost as good as the Realme 7 Pro, despite having the same processor. The reason is because of the optimization of MIUI for gaming. However, the POCO X3 NFC with the Snapdragon 732G delivers a more stable 60 FPS even in tense scenes, making it the best choice for gamers in this segment.

Compared to flagships (e.g. Xiaomi Mi 10T with Snapdragon 865), the difference is huge: the same HDR + Ultra will give 40-50 FPS without drawdowns. But the price is completely different. For budget gaming, the Redmi Note 9S remains one of the best options.

💡

If your budget is limited to 15-18 thousand rubles, then Redmi Note 9S is the best choice for PUBG Mobile on Smooth + Extreme settings. For higher FPS on Ultra-graphics, you will have to spend on a smartphone with Snapdragon 8xx.

How to increase FPS in PUBG Mobile on Redmi Note 9S: step-by-step instructions

If you're not happy with the current FPS, you can try optimizing the system.

Enable Game Turbo in MIUI|

Clear the cache of games and systems |

Turn off background processes |

Use the GPL Tool for fine-tuning |

Update the GPU drivers via Fastboot-->

Let's take a closer look at each item:

1. Game Turbo: MIUI has a built-in game mode that blocks notifications and optimizes resources. It goes like this: Settings → Special features → Game Turbo. Add PUBG Mobile to the list and activate Performance and No Notifications options.
2. Cache Cleanup: Go to Settings → Apps → PUBG Mobile → Storage → Clear the cache. Also clear the system cache through Settings → Storage → Cleanup.
3. Background Processes: Use Settings → Apps → Autorun to disable autoload of unnecessary apps, especially the gluttonous Facebook, Instagram and some launchers.
4. GPL Tool: This is a third-party app (requires root or ADB) to fine-tune graphics. It allows you to force 60 FPS on even on Balanced settings. You can download it on XDA Developers, but beware - incorrect settings can lead to the crashes of the game.
5. GPU driver update: Fastboot can flash fresh drivers for Adreno 618. Instructions are available on thematic forums (e.g. 4PDA), but this is risky for beginners.

⚠️ Attention: Use GPL Tool or firmware drivers through Fastboot can lead to a ban account in the PUBG Mobile for cheating. Do it at your own risk, and only if you understand the consequences.

Another way is to lower the screen resolution, and in PUBG Mobile, you can manually set the resolution below the native (2400×1080).

1. Start the game and go to Settings → Graphics.
2. Select User Resolution and set 720p or 900p.
3. Save the settings and restart the game.

This will increase the FPS by 10-15%, but the picture will become less clear. The optimal balance is 900p on the Smooth settings.
