How to pump Xiaomi: a complete guide to speeding up and improving your smartphone

Xiaomi smartphones are known for their value for money, but even flagship models eventually start to slow down. MIUI. Fortunately, most problems are solved without contacting the service center - just know a few key tricks.

This article is not about the “magic” programs that promise to overclock the processor in the processor. 2 Real-world optimization methods that work on models from Redmi Note 10 Xiaomi 14 Ultra. We will analyze both basic settings (cleaning the cache, turning off the background) and advanced tricks (changing animations, adjusting the cores). CPU). Important: all methods are checked on current versions MIUI 14/15 They do not require the rights of a superuser (root).

If your Xiaomi has become slower to work, quickly discharge or overheat - do not rush to buy a new gadget. 80% This problem can be solved programmatically 10-30 Let's start with the simplest and move on to more complex methods.

1. Cleaning the system: remove garbage and unnecessary files

The first step to “pumping” – freeing up space in memory. MIUI It tends to accumulate cache, temporary files, and remnants of deleted applications. Even if you clean the gallery regularly, the system can store gigabytes of invisible garbage.

Start with the built-in Cleanup tool (the broom icon in the app menu).

• 🗑️ Cash of applications (up to) 1-3 GB on loaded devices)
• 📁 Temporary files APK (leftovers after installation)
• 📊 Logs of the system (can take up to 500 MB)
• 🎵 Empty folders and duplicate media files

For deep cleaning, go to Settings → Memory. → Clean up your memory and select Deep Clean. This mode analyzes even system folders (but doesn't touch user data). After cleaning, reboot the device, which will allow the system to reassemble the cache from scratch, which will speed up the work on the system. 10-15%.

💡

If the built-in cleaning doesn’t help, try third-party utilities like SD Maid (requires you to manually enable file access in Android settings) finds garbage where it is located. MIUI «see».

Pay special attention to the Download folder, which often accumulates unnecessary files weighing several gigabytes. DCIM/.thumbnails (Photos that can be completely cleaned without consequences.

Optimization MIUI: Disable unnecessary functions and animations

MIUI — One of the heaviest shells of Android, especially on Redmi's budget models, many of which work in the background, consuming resources. 20-30%.

First, deactivate unnecessary system applications:

1. Go to Settings → Applications → Application Management
2. Slip on three dots in the upper right corner and select "Show all processes"
3. Find and disconnect: 📡 Mi Roaming (if you don't use roaming) 🎵 Mi Music and Mi Video (if you use other players) 📰 Mi Browser (if you prefer Chrome) 🛒 GetApps and Mi Pay (if you don’t use Xiaomi services)

Next, reduce or disable the animation of the interface.

1. Activate Developer Mode (7 times tap on Settings) → The phone. → Version. MIUI)
2. Back to Settings → Additionally. → For developers
3. Find the items: "Scope of window animation» → 0.5x or "Disable" "Scale of transition animation» → 0.5x «Duration of the animator» → 0.5x

These changes will make the interface visually faster, although the real increase is not expected. FPS It's not for gaming smartphones. - Black Shark, POCO F) more appropriate section on acceleration GPU.

3. Background and autoboot management

One of the main reasons for the “brakes” – applications that work in the background. MIUI It aggressively caches processes, which eats up RAM, and setting limits will free up resources.

First, limit background activity:

1. Go to Settings → Applications → Application Management
2. Select an app (such as Facebook or Instagram)
3. Slip the battery» → «Limit background activity»
4. For maximum savings, select Strict Limits (but note that notifications may come with a delay)

Then set up autoboot. Many programs start when you turn on your phone, even if you're not using them.

1. Install the AutoStart Manager app (requires special access permission)
2. In the list, find and disable the autoboot for: 📱 Messengers (if you do not need notifications immediately after activation) 🎮 Games (they often run background processes for a "fast start») 🛒 Markets (such as GetApps or Google Play)

Disable the autoload of unnecessary applications|

Limit background activity for social networks |

Check the list of “Recently used” in the app menu|

Reboot your phone after the changes-->

⚠️ Note: Do not disable autoboot for system processes called com.android. or com.miui..This can cause unstable shell operation.

For advanced users: in developer mode, you can limit the number of background processes. 4-6 GB RAM – “Standard Limit” or “Maximum” 4 process" (included in the Developers' → Process limit).

4. Overclocking of the processor and GPU: Safe methods without rooting

If your Xiaomi supports Game Turbo technology (most models on Snapdragon) 700/800 In the series, you can activate hidden performance modes. They increase the clock speed. CPU/GPU under load, but do not affect the battery life in idle.

How to turn on:

1. Open Settings and find the Special Features section (or “More”)
2. Select "Game Turbo» → «Performance settings»
3. Activate Performance or Extreme Performance (not available on all models)
4. For gaming smartphones (POCO F3, Black Shark) turn on “Overclocking” GPU» same menu

On some devices (e.g. Xiaomi) 12T or Redmi K50) You can use the hidden mode "Ultra Performance Mode" to activate it:

adb shell settings put global force_high_performance_mode 1

This command requires a connection to the PC and enabled debugging. USB. Effect: increase in benchmark tests to 10-15%, but increasing heat.

⚠️ Note: On budget models (Redmi) 9A, POCO M3) Overclocking can lead to trottling (automatically reducing the frequency due to overheating). If after activation of the mode, the smartphone began to warm up strongly, return the settings to the factory.

5.Memory Optimization: How to Free RAM and Accelerate Multitasking

MIUI It's known for eating away at RAM, leaving little resources for user applications, especially on devices with a computer. 3-4 GB RAM. To solve the problem will help manual adjustment.

First, check which apps consume the most memory:

1. Go to Settings. → Annexes → Application management → Memory.
2. Sort the list by “Use of RAM”
3. Close unnecessary processes manually (Clean the button)

On devices with virtual memory (for example, Redmi Note 12 Pro)+) You can increase the swap file:

1. Install. RAM Expander from Google Play
2. Select. 1-2 GB of internal memory under virtual RAM
3. Reset the device

For models with Snapdragon 8 Gen 1/2 (for example, Xiaomi 12S Ultra) is available in Developer mode, and turn it on and select Aggressive Release, which will make the system more active in clearing the cache of background applications.

6. Battery setup: how to extend the running time without losing performance

Many pumps increase energy consumption, and in order for a smartphone to work quickly and long, you need to balance the settings.

1. Charge your phone to 100%
2. Disconnect from charging and use until full discharge (0%)
3. Charge again to 100% without interruptions
4. Repeat the cycle 2-3 times

Then optimize the cost:

• 🔋 Include “Adaptive Charging” in Settings → Battery (prolongs battery life)
• 🌙 Activate the Dark Theme (on the AMOLED-The screen saves up to 15% of the charge)
• 📶 Turn off "Network search" 5G», If not used (Settings) → SIM-maps and mobile networks)
• 🔍 Reduce the “screen refresh rate” to 60 Hz (if you have one) 90/120 Hz display)

For advanced users: In developer mode, disable Battery Background Optimization for critical applications (messengers, navigators) and allow them to work in the background without restrictions, but slightly increase the cost.

💡

On models with a battery of 5000+ mAch (Redmi Note) 11S, POCO M5) You can safely activate the “Performance” mode – the energy reserve will last for a day even with active use.

If the smartphone is quickly discharged in standby mode, check the consumption in sleep mode:

1. Go to Settings. → Battery → Battery consumption
2. Slip on the chart and select "Details"
3. If an application is consuming >5% in the background – limit its activity (Section 3)

7.Firmware and kernel updates: when it really helps

Regular updates MIUI Not only do they add new features, they also optimize the system, but not all updates are useful, some of them bring bugs or increase the load on the hardware.

How to properly update:

• 🔄 Check the updates once in a while. 1-2 Months (no need to install every beta version)
• 📥 Download firmware only through Settings → The phone. → System update or official website en.miui.com
• 🛠️ Before updating, make a backup through Settings → Additionally. → Backup and reset
• 🔋 Charge the battery by at least 50% (when upgraded via recovery)

If after the update, the smartphone began to work worse:

1. Clean the cache through Settings → Memory → Cleanup
2. Reset the device 2-3 Sometimes the system is optimized after several reboots)
3. If the lags are saved, reset the settings (without data loss)

For enthusiasts: on some models (Xiaomi) 11T, POCO X3 Pro) custom cores (e.g. FrancoKernel or Kirisakura) are available, which improve processor frequency management and reduce heat, but require unlocked bootloader and root rights.

8. Alternative firmware: when to switch to caste

If all the optimization techniques didn’t work, consider installing an alternative firmware.This is a radical step, but it could breathe a second life into an old smartphone.

The advantages of custom firmware:

• ⚡ Higher performance (no heavy shell) MIUI)
• 🆕 Longer support for updates (even for older models)
• 🛠️ More opportunities for fine-tuning

Cons:

• ⚠️ Loss of warranty (if bootloader unlocked)
• 📸 Camera issues are possible (not all custom phones support proprietary Xiaomi drivers)
• 🔋 Increased battery consumption (on some assemblies)

Popular firmware for Xiaomi:

Installation instructions (briefly):

1. Unlock the bootloader via Mi Unlock Tool (requires Xiaomi account binding)
2. Install custom Recovery (TWRP or OrangeFox)
3. Download the firmware from the official website (for example, lineageos.org)
4. Then, go through the sleeves (be sure to make a backup!)

⚠️ Attention: On models with Snapdragon 4xx (Like Redmi. 9C) custom firmware may work unstable due to weak iron. 4pda.ru or XDA Developers.
