The Xiaomi Redmi 8 Pro is one of the most popular smartphones in the budget segment, and is still widely used due to its reliability and fine-tuning capabilities. One hidden feature that can significantly improve the device’s performance is the Pro Mode, which allows you to manually monitor CPU performance, graphics, and control cooling and power consumption.
However, many users do not even suspect its existence - in the standard settings. MIUI In this article, we will discuss in detail how to turn on Profi mode on the Redmi 8 Pro, what settings can be adjusted, and how this will affect the performance of the smartphone. You’ll learn how to overclock a gaming device, optimize it for long-term autonomy, or find a balance between performance and heating.
It is important to understand that incorrect settings can lead to overheating or rapid discharge of the battery, so we will also give recommendations for safe use of the mode and tell you which parameters are best not to touch unnecessarily.
What is the Profi Mode on Xiaomi and why is it necessary?
Pro Mode is a hidden function in the firmware MIUI, It allows the user to manually control the clock speed of the processor, the graphics accelerator, and the cooling and energy saving settings. By default, the smartphone operates in automatic mode, where the system itself allocates resources depending on the load. However, it is not always optimal:
- 🎮 For gamers: in games there may be a drawdown FPS due to heating or power consumption restrictions.
- 🔋 For battery saving: background processes can consume more energy than needed.
- ⚡ Overclocking: Some tasks (such as video rendering) require maximum performance.
- ❄️ For cooling: with prolonged load, the smartphone can overheat, which leads to trottling (automatic power reduction).
On the Redmi 8 Pro (a model with a Snapdragon 665), the Pro mode is particularly useful, as this chipset is prone to overheating at high loads.
- 📈 Raise FPS in games by turning off heating restrictions (but this will reduce battery life).
- 🔄 Optimize multitasking by increasing the limit of background processes.
- 🛡️ Extend battery life by limiting maximum processor frequency.
But there is a downside: improper settings can lead to high heat, rapid discharge or even unstable system operation, so before activating the Profi mode, it is recommended to familiarize yourself with the basic principles of operation of processors and cooling systems in smartphones.
How to turn on Profi mode on Redmi 8 Pro: step-by-step instructions
Activating Pro Mode on Redmi 8 Pro Requires Access to Hidden Settings MIUI. There are two main ways, through the engineering menu and through third-party apps, and we'll look at both, but we'll start with the most reliable one, through the standard tools of the system.
Method 1: Through the Engineering Menu (without root)
This method does not require superuser rights and works on most versions. MIUI (including MIUI 12/13/14):
- Open the phone app and enter the combination: ##4636##
- In the menu that opens, select Battery Information** (or Battery Information).
- Slip on the top right corner of the screen (where the three-dot icon is displayed) 5 times in a row – this will open the hidden Performance menu**.
- In the new window, select Pro Mode** and activate it.
If this method doesn’t work, try the alternative code:
##6484##Method 2: Through the application «CPU Monitor (requires unlocking of the bootloader)
If the engineering menu is not available (for example, due to operator restrictions), you can use third-party utilities — CPU Developer's Monitor XDA Developers, but it's going to take a lot of work:
- 🔓 Unlocked bootloader (bootloader).
- 📱 Installed Magisk application (to obtain root rights).
- 🔧 Included debugging by USB (Settings → The phone. → Version. MIUI — Tap 7 times, then go back to Settings → Additionally. → For developers → Debugging by USB).
After installation CPU Monitor:
- Launch the application and provide root access.
- Go to the profiles tab**.
- Select “Create a new profile”** and set the settings manually.

The main settings of the Profi mode: what can be changed
Once you activate the Profi mode, you will have a few key parameters that you can customize to your needs.
| Parameter | What regulates | Recommended values | Risks of improper setting |
|---|---|---|---|
| Max. CPU frequency. | Limits the clock speed of the processor (in GHz). On the Snapdragon 665, the maximum value is 2.0 GHz. | 1.8–2.0 GHz (for gaming), 1.4–1.6 GHz (for battery saving) | Overheating, rapid discharge, trottling |
| Min. frequency CPU | Specifies the minimum frequency below which the nuclei will not fall even in simple. | 0.3–0.5 GHz (optimum for balance) | Increased energy consumption in simple |
| Graphic Accelerator (GPU) | Controls the frequency of the Adreno 610 graphics processor. | 500–650 MHz (for games), 300–400 MHz (for savings) | Artifacts in games, overheating |
| Cooling (Thermal) | Controls the aggressiveness of the cooling system. | Balanced (balanced) or Performance (maximum performance) | Overheating over 60°C, automatic shutdown |
| Task planner | It determines how resources are allocated between processes. | cfq (for multitasking) or noop (for performance) | Interface freezes, lags |
It is important to understand that on the Redmi 8 Pro, Pro Pro mode does not support dynamic real-time frequency change - all settings are applied globally and are valid until a reboot or manual reset. CPU For the game, it will remain so simple, which will lead to increased energy consumption.
We recommend creating separate profiles for different scenarios (for example, “Game”, “Economic”, “Balanced”) and switching between them manually.
💡
If after changing the settings, the smartphone began to warm up strongly, return the Thermal option to the Balanced value and restart the device.
Optimal settings for different use cases
Depending on how you use the Redmi 8 Pro, the settings for Pro Pro will vary, and below we will show you the tried-and-true configurations for the most common tasks.
🎮 Profile for games (maximum) FPS)
If you play heavy games like Genshin Impact, Call of Duty Mobile or PUBG, This profile will help you maximize productivity:
- 🔹 Max. frequency. CPU: 2.0 GHz
- 🔹 Min. frequency CPU: 1.0 GHz (so that the cores do not fall asleep when loaded)
- 🔹 GPU: 650 MHz
- 🔹 Refrigeration: Performance
- 🔹 Planner: noop
⚠️ Note: With such settings, the processor temperature can reach 65-70°C, and the battery will run 15-20% per hour. Use this profile only when the charger is connected or with an external cooler.
🔋 Profile for battery saving (maximum autonomy)
If you want your smartphone to last as long as possible (for example, on a hike or in the absence of an outlet), use these options:
- 🔹 Max. frequency. CPU: 1.4 GHz
- 🔹 Min. frequency CPU: 0.3 GHz
- 🔹 GPU: 300 MHz
- 🔹 Cooling: Power Save
- 🔹 Planner: cfq
In this mode, the smartphone will work slower, but the battery life will increase by 20-30%, ideal for watching videos, reading or using instant messengers.
⚖️ Balanced profile (for everyday tasks)
If you want a balance between performance and energy consumption, set the following values:
- 🔹 Max. frequency. CPU: 1.8 GHz
- 🔹 Min. frequency CPU: 0.5 GHz
- 🔹 GPU: 450 MHz
- 🔹 Cooling: Balanced
- 🔹 Planner: cfq
This profile is suitable for most users: social networks, photos, light games (Clash Royale, Brawl Stars) will work smoothly, and the battery will last all day.
💡
Do not save profiles with extreme settings (for example, maximum frequency). CPU + shut off cooling as permanent, which can lead to permanent battery damage or hardware trottling (when the processor starts to work worse due to frequent overheating).
Frequent problems and their solutions
When working with the Pro mode on Redmi 8 Pro, users often encounter errors, and let’s look at the most common ones and how to fix them.
🔥 The smartphone is very warm even in simple
If the temperature of the processor rises above 50°C without load is most likely a problem in the following settings:
- 🔸 Minimum frequency too high CPU (set not below 0.3 GHz).
- 🔸 Cooling mode is set in Performance (switch to Balanced).
- 🔸 Heavy applications are running in the background (check in Settings). → Battery → Battery utilization).
Decision:
- Reset the Profi mode settings to factory.
- Set a minimum frequency. CPU at 0.3 GHz.
- Clear the cache in Settings → Storage → Clear the cache.
⚡ The battery is running out too fast.
If after activation of the mode of Profi autonomy fell by 30-50%, check:
- 🔸 Maximum frequency CPU (It should not exceed 1.6 GHz in daily use).
- 🔸 Frequency. GPU (400 MHz is optimal for most tasks).
- 🔸 Background processes (turn off autosynchronization for unnecessary applications).
Decision:
1. Go to Settings → Battery → Battery Mode.
2. Select "charge savings."
Set the Profi mode to:
- Max. CPU frequency: 1.4 GHz
- GPU: 300 MHz
- Cooling: Power Save🐢 The smartphone began to slow down after changing the settings
If the interface MIUI It started to hang, the reasons may be as follows:
- 🔸 Too low maximum frequency CPU (less than 1.0 GHz).
- 🔸 Incorrect task scheduler (e.g. deadline instead of cfq).
- 🔸 Conflict with other SEOs (e.g. Greenify or AccuBattery).
Decision:
⚠️ Note: If the lags appeared after installing a third-party application to manage the Profi mode (for example, CPU Monitor), try rolling back changes through Safe Mode: Press the power button until the turn off menu appears. Hold your finger on Turn off** - prompt to go to Safe Mode. In Safe Mode, remove the problem app.

Comparison of Profi mode with other methods of overclocking
Pro mode isn’t the only way to increase the performance of the Redmi 8 Pro. Let’s look at how it compares to alternative optimization methods:
| Method | Needs root? | Productivity effects | Risks. | Difficulty setting up |
|---|---|---|---|---|
| The Profi regime | ❌ No. | ⬆️ Moderate (up to 15-20% in games) | Overheating, quick discharge. | ⭐⭐ (simple) |
| Engineering Menu (MTK) | ❌ No. | ⬆️ Minimum (fine network settings) | Loss of communication, module errors | ⭐⭐⭐ (middle-of-the-road) |
| Castomic core (e.g., FrancoKernel) | ✅ Yes. | ⬆️⬆️ Significant (up to 30% in synthetic tests) | Brick, unstable job. | ⭐⭐⭐⭐ (difficult) |
| Undervolting (reducing voltage) | ✅ Yes. | ⬆️ Minor (battery savings) | Instability, occasional rebuttals | ⭐⭐⭐⭐ (difficult) |
| Cleaning cache and background processes | ❌ No. | ⬆️ Minimum (interface acceleration) | Loss of application data | ⭐ (simple) |
As you can see from the table, Profi mode is one of the safest and easiest ways to overclock, but it's inferior in efficiency to custom cores or undervolting. If you want maximum performance and you're willing to take risks, consider installing an alternative core. However, for most users, the Profi mode will be enough.
Important: Custom cores and undervolting require unlocked bootloader and root rights, which deprives you of the official warranty Xiaomi.In addition, improper manipulation can lead to a "brick"** (complete inoperability) of the device.
Security and optimization tips
To use the Profi mode only benefit, follow these recommendations:
🛡️ How to avoid overheating
- 🔹 Do not set the maximum frequency. CPU above 2.0 GHz for a long time.
- 🔹 Use cooling stands or external fans under intense loads.
- 🔹 Keep track of the temperature through apps like AIDA64 or CPU Monitor.Critical mark for Snapdragon 665 - 75°C.
- 🔹 Avoid using Profi mode and fast charging at the same time – this increases heating.
🔋 How to extend the life of the battery
- 🔹 Do not keep your smartphone on charge with Pro mode enabled (especially with a profile for games).
- 🔹 Periodically (once every 1-2 months) calibrate the battery: fully discharge, then charge to 100% without interruptions.
- 🔹 Avoid extreme temperatures (below 0)°C and above 40°C).
- 🔹 Use original or certified chargers.
⚙️ Optimization for long-term stability
- 🔹 Don’t change the task scheduler settings unnecessarily – this can lead to lags.
- 🔹 Update regularly MIUI — New versions improve energy management.
- 🔹 If you notice that the smartphone began to reboot on its own, return the settings of the Profi mode to the factory.
💡
The Pro mode is not a magic wand for overclocking. Its main advantage is flexibility: you can customize your smartphone for a specific task, but do not expect miracles. The Snapdragon 665 in the Redmi 8 Pro has limited potential, and even overclocking it does not compare with the flagships on the Snapdragon. 8xx.
