How to set up Xiaomi for gaming: from overclocking to cooling

Xiaomi smartphones have long ceased to be budget “callers” – modern models like the Redmi Note 13 Pro+ or POCO F6 in performance are not inferior to the flagships of other brands. But even top-end hardware requires the right optimization to give stable 60+ FPS in Genshin Impact, Call of Duty Mobile or Honor of Kings. Without competent settings, you risk overheating, lags and sudden departures – especially on devices with Snapdragon 7+ Gen 2 or Dimensity 9200+ processors, which are prone to trolling.

In this guide, we will break down hardware and software optimization techniques for gaming on Xiaomi, including hidden settings. MIUI, All recommendations are tested on current models from 2023-2026 and do not require root rights (although for advanced users we have added a bonus section with a new version of the system). ADB-If your smartphone is warming up like an iron or slowing down at high settings, you're on the right track.

⚠️ Important: Optimizing for games can reduce battery life and speed up battery wear!

1. Hardware optimization: cooling and power

The first thing to do is to ensure stable cooling and power. Even the most powerful Snapdragon 8 Gen 3 processor in the Xiaomi 14 Ultra will trott (reset frequencies) if the temperature exceeds 45-50 ° C. Let's start with physical methods:

• 🔋 Use the original power supply (or certified with Quick Charge support) 4+/PD 3.0). Cheap charging can limit productivity.
• ❄️ Remove the case before a long game session - especially if it's dense or silicone.Tests show that the case increases the temperature by 3-7°C.
• 🌡️ Play in a cool room (optimally 20–25)°C) At temperatures above 30°C risk of trolling rises by 40%.
• 📦 Lift your smartphone (for example, on a stand) – this improves air circulation around the case.

For active cooling models (such as the Black Shark 5 Pro or the POCO F5 with a fan in the box), use branded accessories. Black Shark's fan lowers the temperature by 8-12 ° C, which gives an increase of 10-15 FPS in heavy games.

⚠️ Warning: Do not use your smartphone on soft surfaces (bed, sofa) – this blocks the vents (if any) and worsens the heat sink.

If your Xiaomi supports wireless charging, turn it off in settings (Settings → Battery → Wireless Charging). The induction module heats the case, which leads to trottling after 20-30 minutes of play.

2. MIUI settings for maximum performance

MIUI is optimized by default to balance performance and time, but for gaming, that balance needs to shift.

1. Performance mode: Go to Settings → Special features → Performance mode and select High performance. This disables background optimization and increases the FPS limit.
2. Background Limitation: In Settings → Applications → Application Management → Autostart disable autostart for all unnecessary applications (messengers, social networks) This will free up 10-15% of RAM.
3. Animation and transitions: Reduce or disable animation in Settings → About Phone → MIUI version (tap 5 times, then Developer Settings → Animation Speed). Select Animation disabled or 0.5x.
4. Screen resolution: If your smartphone supports QHD+ (e.g. Xiaomi 13 Ultra), switch to Full HD+ in Settings → Display → Screen resolution. This will reduce the load on the GPU by 20-30%.

On Snapdragon 8 Gen 2/3 models (such as Xiaomi 14), enable Force GPU Rendering in the developer settings. This speeds up graphics processing, but can increase power consumption by 5-10%.

3.Graphics settings in games: balance between FPS and quality

Each game has unique graphics settings, but there are universal optimization principles for Xiaomi:

For Genshin Impact on Xiaomi, the best settings are:

• Resolution: 720p (or 900p for Snapdragon 8+ Gen 1/2)
• FPS: 60 (on the POCO F5 Pro or Xiaomi 13T Pro you can try 90 FPS, but with the risk of overheating)
• Graphics quality: Medium (or Low for stable 60 FPS)
• Shadows: Low
• Environmental effects: Low

In Call of Duty Mobile, activate Extreme FPS in the graphics settings. On the Snapdragon 7+ Gen 2 (e.g. Redmi Note 13 Pro+), this gives a stable 90 FPS at Medium resolution.

💡

In games that support the Vulkan API (e.g. PUBG Mobile), choose this mode over OpenGL ES. Vulkan reduces CPU load by 10-15% and reduces input delays.

4. Overclocking and frequency control (without root)

Without the superuser rights (root) to overclock the processor is impossible, but you can fix the maximum frequencies to avoid trottling.

1. Activate the developer mode (tap 5 times on the MIUI version in Settings → About phone).
2. Go to Developer Settings → Background Process Limitation and select No Limits.
3. Turn on Do not turn off the screen while charging (useful for long sessions).
4. Install the Game Turbo app (pre-installed on most Xiaomi) and activate it in its settings: 🔄 High-performance mode 📊 Monitoring FPS 🚫 Blocking notifications

For advanced users, you can use ADB to record the CPU frequencies, connect your smartphone to your PC, enable USB Debugging, and follow the command:

adb shell settings put global force_high_perf true

This forces the processor to stay at maximum frequencies, but it increases the heat significantly. Use only with active cooling!

⚠️ Note: Frequency fixation on Dimensity processors (e.g., in POCO X6 Pro) may cause overheating above 50°C's in 15 minutes. Watch the temperature in the app. CPU Monitor.

5. Battery and power optimization for long sessions

Games quickly put the battery down, but a few tricks will help to extend battery life:

• 🔌 Play from charging (but not below 20% and not above 80% of the charge – this minimizes battery wear and tear).
• 🌑 Include a dark theme in games and MIUI (saves up to 5% of the charge on AMOLED-screen).
• 📶 Turn it off. 5G/LTE, If you play over Wi-Fi, the modem consumes a lot of power even in the background.
• 🔊 Turn down the volume or use headphones – smartphone speakers consume an additional 3-7% charge per hour.

In the battery settings (Settings → Battery → Battery Mode), select Performance over Balance or Saving. Also turn off adaptive brightness and set a fixed value of 50-70%, which will reduce the load on the light sensor.

For models that support fast charging (such as the Xiaomi 14 Pro with 120W), use original charging. Cheap counterparts can limit power, which leads to FPS drawdowns during charging.

6. Additional tricks: from gaming triggers to custom firmware

If standard methods do not give the desired result, try these advanced techniques:

• 🎮 Gaming triggers: on Black Shark models or POCO F with physical buttons (Shoulder Buttons) assign them to shoot/aim in shooters. This will speed up the reaction by 10-20 ms.
• 🖥️ Game Space Mode: In Game Turbo, activate Game Space – this blocks swipes around the edges of the screen and disables navigation gestures.
• 🔧 Custom firmware: Xiaomi with unlocked bootloader can install Pixel Experience or LineageOS for pure Android without background processes MIUI. Growth FPS — 10-15%.
• 🌐 DNS In games like Free Fire or PUBG Mobile use Cloudflare DNS (1.1.1.1) or Google DNS (8.8.8.8) to reduce ping.

For owners of Xiaomi 12T Pro, 13 Pro or 14 Ultra with Snapdragon 8+ Gen 1/2 processor, there is an informal method of overclocking through ADB:

adb shell settings put global gpu_max_clock < value>

Where <value> is the maximum GPU frequency (e.g. 800,000,000 for the Adreno 730) Dangerous! Exceeding the standard values can cause the device to overheat and turn off.

💡

Custom firmware is performance-enhancing, but it's not warranty-free and it can be buggy. Use only if you're risk-averse.

7.Testing and monitoring: how to check the results of optimization

After applying all the settings, check the changes with these tools:

• 📊 GameBench - Measuring FPS, Temperature and energy consumption in real time.
• 🌡️ CPU Monitor – shows the load on the processor cores and temperature.
• 🎯 3DMark (Sling Shot Extreme test – evaluates overall graphics performance.
• 🕒 AccuBattery – tracks battery discharge during play.

Take the test in Genshin Impact (Mondstadt area) or Call of Duty Mobile (Battle of the Royals mode):

1. Start the game and play 15-20 minutes at maximum settings.
2. Check the average FPS and temperature in GameBench.
3. If the FPS drops below 40 or the temperature exceeds 48°C, lower your graphics settings.

On the POCO F6 Pro with Snapdragon 8+ Gen 1 after optimization, it is possible to hold 55-60 FPS in Genshin Impact at the Average/60 FPS settings at a temperature of 42-45 ° C (with external cooling).
