What does “acceleration” mean on a Xiaomi phone: overclocking, optimization or marketing?

Have you ever noticed a mysterious “Accelerate” item in the Xiaomi smartphone settings and wondered what it actually does? MIUI — From the old Redmi Note 7 to the flagship Xiaomi 14 Ultra — but its purpose remains vague for most users, some believe that it is “overclocking the processor”, others – that is just a marketing ploy, and still others fear that the acceleration will reduce the life of the battery. In this article, we will look at what is really behind the acceleration function, how it works at the system level, and when it is worth using (and when it is not).

Spoiler: This Is Not The Magic Button That Will Turn Your Redmi 9A But when applied correctly, acceleration can dramatically improve interface responsiveness, reduce gaming lags, and even extend battery life. The key is to understand the mechanisms behind it. We analyzed Xiaomi's official documentation, tests from enthusiasts with the help of the new technology. 4PDA, and source code data MIUI, to give you a comprehensive answer.

What is "acceleration" in MIUI: technical explanation

The Acceleration feature (or “Ultra Battery Saver”/“Game Turbo” in different versions of the firmware) is a set of optimizations that Xiaomi has implemented to combat two key problems: slowing the interface over time and inefficient energy consumption. Unlike “overclocking” in the traditional sense (as on a PC), it does not increase the clock speed of the processor.

• 🔄 Redistributes resources: limits background processes to priority tasks (e.g. games or cameras).
• ⚡ Optimizes the Android core: uses patches from Xiaomi for more aggressive memory management (e.g., kills unused apps faster than stock Android).
• 📉 Reduces the load on GPU: In some modes, it lowers the resolution of rendering in games (analogue) FSR PC-only).
• 🔋 Adapts energy consumption: dynamically adjusts processor frequencies depending on temperature and battery charge.

It's important to understand that acceleration is not a single function, but a set of tools that are activated in different scenarios.

• B Settings → Battery → Performance mode can be “balance” or “high performance».
• B Settings → Special facilities → Acceleration of animation is a change in the speed of transitions in the interface.
• In games through Game Turbo, this is the “Extreme Performance” mode.

According to tests from GSMArena on Xiaomi 13 Pro, the inclusion of acceleration in games gives an increase FPS 8-12% (in Genshin Impact from 50 to 55 fps), but the processor temperature rises by 5-7°C, and battery life is reduced by 15 to 20 percent, so it's always a compromise.

Where to find acceleration settings on Xiaomi (step-by-step instructions)

The location of the function depends on the version MIUI We've put together the actual paths for firmware in 2023-2026:

If you have a custom firmware (e.g. Xiaomi.eu or custom), the path may be different.

1. Open Settings and search for “acceleration” or “performance.”
2. Check the About Phone section. → Version. MIUI — If you have a Global ROM, Some options may be hidden.
3. Nana POCO and Black Shark look for proprietary utilities (like Game Turbo or Shark Space).

Types of acceleration on Xiaomi: which mode to choose?

V MIUI There are at least 4 types of acceleration, and each is designed for different tasks:

1. Performance mode (Battery & Performance)

Located in Settings → Battery. There are three main options:

• 🔄 Adaptive: the system chooses the balance between performance and energy consumption, suitable for everyday use.
• ⚡ High performance: maximum CPU frequencies, but the battery goes down 20 to 30 percent faster. Useful for video editing or games.
• 🔋 Energy savings: limits background processes and clock speeds, increases operating time, but the interface can slow down».

2. Accelerated animation (Developer Options)

This trick is familiar to many "advanced" users, to include:

1. Activate Developer Mode (7 times click on the MIUI version in About Phone).
2. Go to Settings → Additional → For developers.
3. Find the points of the Windows Animation Scale, the Transition Animation Scale and the Animator Duration Scale.
4. Set the value 0.5x or disconnect.

⚠️ Caution: Disabling animations will make the interface visually faster, but may break the logic of some apps (e.g., Instagram or banking apps).

3. Game Turbo (for games)

Xiaomi's signature gamer chip, including:

• Automatically when you start the game (a floating panel appears).
• Or manually in Settings → Annexes → Game Turbo.

What's going on?

• 🎮 Block notifications and calls during the game.
• 📊 Monitoring FPS, temperature and loading CPU/GPU.
• ⚡ Extreme Performance (acceleration to maximum frequencies).
• 🔊 Optimizing sound for shooter games (boosting steps and shots).

4 Ultra Battery Saver (Ultra Battery Saver)

This is "backward acceleration" -- the system sacrifices performance for autonomy, turns on at low charge (15%) or manually in Settings. → Battery.

What's off:

• 🚫 Background synchronization (mail, messengers).
• 🚫 Auto-update of applications.
• 🚫 Widgets and live wallpaper.
• 🚫 Limiting the clock speed of the processor to 60-70% of the maximum.

💡

High Performance mode is only useful for short sessions (games, rendering), and prolonged use leads to overheating and battery degradation.

Myths about acceleration on Xiaomi: what is true and what is not

There's a lot of rumors about the acceleration function, and we've collected the most popular ones and tested them in practice.

❌ Myth 1: Acceleration accelerates the processor to the limiting frequencies»

🔍 Reality: Most Xiaomi smartphones (except Black Shark) don’t have hardware overclocking. The processor works within the manufacturer’s established frequencies. “Acceleration” only changes the policy of power management, forcing the cores to stay longer at high frequencies.

For example, on the Snapdragon 8 Gen 2 in Xiaomi 13 Ultra, the maximum frequency of the large core is 3.2 GHz. In the “High Performance” mode, the processor will keep this frequency longer, but will not exceed it.

❌ Myth 2: Acceleration ruins the battery»

🔍 Reality: Acceleration doesn't hurt the battery, but heat does. If you play Genshin Impact 2 hours straight with Extreme Performance on, the battery will heat up to 40 to 45.°C, which accelerates the degradation of lithium-polymer elements.

📊 According to a study by Battery University, continuous operation at temperatures above 35°C reduces battery life by 20 to 30 percent per year:

• ✅ Use acceleration in short sessions (up to 30-40 minutes).
• ✅ Watch the temperature in Game Turbo or through the app CPU Monitor.
• ✅ Avoid simultaneous charging and intense loading.

❌ Myth 3: Acceleration only works on flagships»

🔍 Reality: Even budget models like Redmi 10A or POCO M5 They have basic acceleration mechanisms, but they're less noticeable:

• On Helio. G35 (redmi 9C) acceleration simply turns off background processes, freeing up RAM.
• On the Snapdragon 480 (in) POCO M3 Pro) adds graphics optimization in games (reduced resolution).

The difference is that on flagships (Snapdragon 8 Gen 3, Dimensity 9200)+) acceleration involves hardware features (for example, ARM DynamIQ for dynamic load distribution between cores).

When to turn on acceleration and when not

Acceleration is a tool, not a panacea, and here are specific scenarios where it is justified or harmful:

✅ When to include:

• 🎮 Games: Genshin Impact, Call of Duty Mobile, PUBG — here FPS You can see it. Use the Game Turbo. → Extreme Performance.
• 🎥 Video editing: In CapCut or KineMaster, acceleration reduces rendering time by 10-15%.
• 📸 Shooting in 4K/8K: Xiaomi. 13 Ultra or Redmi K60 Pro this reduces the lags when recording.
• 🔄 After updating MIUI: New versions often “brake” the first days – acceleration helps the system “settle down».

❌ When not to include:

• 🔋 Charging below 20%: Risk of battery overheating and sudden shutdown.
• ☀️ Heat (over 30)°C indoors: Processor temperature may exceed 50°C.
• 📱 Background: If the phone just lies and syncs the mail - the acceleration only consumes the battery.
• 🚗 Navigation: In Google Maps or Yandex.Navigator acceleration does not give an increase, but warms the phone.

⚠️ Note: On models with MediaTek Helio processors (e.g. Redmi) 9A, POCO C31) And if you do that, you can get trottling, which is when the processor artificially lowers the frequencies because it's overheating, and then the phone starts to lay down even more.

How to Check if Acceleration is Working on Your Xiaomi

Not all changes are visible, but here are 3 ways to test the acceleration efficiency:

1. Through the built-in MIUI tools

Open the Settings. → The phone. → The condition and pay attention to:

• Temperature. CPU: In acceleration mode, it should be at 3-5°C higher than normal.
• Use of the CPU: The loading schedule of the cores should show a more uniform distribution (without drawdowns).

2. Through third-party applications

Install from Google Play:

• CPU Monitor - shows the frequencies of the cores in real time.
• GameBench - Measuring FPS before and after activation of acceleration.
• AccuBattery tracks the speed of battery discharge.

📌 Test: Launch 3DMark (Benchmark) with the acceleration off and on, the difference in scores will show real gains.

3. Manual interface testing

The easiest way is to open the settings. → Apps and quickly scroll the list up and down:

• 🟢 Without acceleration: possible braking when scrolling.
• 🟡 With acceleration of animation: scroll smoother, but can “suppose” icons.
• 🔴 Full acceleration: scroll as smooth as possible, but the battery goes down faster.

💡

If the phone started to warm up more, but FPS If you're not growing up in games, try resetting Game Turbo to factory settings. Sometimes user profiles conflict with system optimizations.

Alternatives to Built-in Acceleration: What to Do If It Doesn't Help

If standard acceleration settings don’t work, there are a few advanced methods (but they need caution):

1. Optimization through ADB (power-user)

With the help of teams ADB You can manually adjust the performance parameters:

adb shell settings put global force_high_performance true

This command is forced to turn on high performance mode to bring it back.

adb shell settings put global force_high_performance false

⚠️ Attention: Misuse of the right ADB This can lead to a bootloop. Before experimenting, back up through Settings. → System system → Backup.

2. Castomic kernels and firmware

Forums 4PDA and XDA Developers have modified cores (such as Kirisakura or Perseus) that offer:

• 🔧 More aggressive control of processor frequencies.
• 🔋 Optimized energy consumption profiles.
• 🎮 Support for dispersal GPU (chip-on).

📌 Example: On Xiaomi Mi 11 with Perseus core, users note an increase in Antutu by 10-15% compared to the stock core.

3. Cleaning up the system from garbage

Often, the brakes are not iron-related, but are caused by a debris system.

• 🧹 Remove the cache through Settings → Memory. → Clear the cache.
• 🗑️ Disable or uninstall unnecessary system applications (e.g. Mi Video, Mi Music) via ADB:

adb shell pm uninstall --user 0 com.miui.videoplayer

📊 According to the Android Authority, cleaning the cache and removing 5-7 unnecessary system applications can increase free RAM by 300-500 MB, which is equivalent to a 5-10 performance increase%.

4. Hardware modifications (for enthusiasts)

If you are willing to take risks, you can:

• 🔥 Replace the heat paste on the processor (relevant for Xiaomi Mi 10 and older, where the thermal interface is used instead of solder).
• 🔋 Install a larger battery (e.g., in a POCO X3 Pro can be put battery 6000 mAh instead of the standard 5160 mAh).

⚠️ Warning: Self-repairing is not warranty. IP-certification (e.g. Xiaomi 13 with a IP68) disassembly may violate the tightness.
