Optimization of the Xiaomi smartphone: what it is and how to properly conduct it

Xiaomi smartphones based on firmware MIUI They are known for their rich functionality, but over time, even the most productive models begin to slow down. Xiaomi optimization is a set of measures aimed at restoring performance, freeing up memory and extending the life of the device. Many users mistakenly believe that it is enough to simply clear the cache or restart the phone, but in fact the process is much deeper.

In this article, we will discuss what exactly is hidden under the term “optimization”, what tools it offers. MIUI, You will learn how to disable unnecessary system processes that eat up to 30% of battery life in the background, how to properly manage application autoloads, and why Xiaomi’s standard “Master of Optimization” doesn’t always do the job. The material will be useful to both beginners and experienced owners of Redmi devices, POCO or Mi.

What is Xiaomi Smartphone Optimization and Why You Need It

Optimization is understood not only to accelerate the system, but also to comprehensively improve all key parameters of the device:

• ⚡ Performance – Eliminating lags, hangs and delays when opening applications.
• 🔋 Autonomy – increasing battery life by disabling “gluttonous” background processes.
• 📱 Memory – freeing internal storage from garbage (cache, duplicate files, residual data of remote programs).
• 🛡️ Security – Closing Vulnerabilities in MIUI, Firmware update and virus check.

Xiaomi smartphones are often criticized for the “heavy” shell MIUI, But the problem is not with the firmware itself, but with its default settings: the manufacturer leaves a host of services (e.g. msa – Mi System Ads) that collect data for personalized advertising and analytics. These processes not only consume charge, but also load the processor.

⚠️ Attention: Optimization is not like factory resets, which deletes all user data, while competent optimization saves files, but restores performance.

Another myth is that the only thing that needs optimization is older smartphones, even flagship models like the Xiaomi 14 Ultra or the other. POCO F6 Pro after 6-12 months of operation begin to work slower due to the:

• 🗑️ Accumulation of temporary files (application cache, system log files).
• 🔄 Memory fragmentation (especially for eMMC devices, not for eMMC devices) UFS).
• 📱 Install dozens of apps, many of which run in the background without the user’s knowledge.

Standard optimization tools in MIUI

Xiaomi is embedding a few basic optimization tools into the firmware, which are limited, but they will be suitable for users who don’t want to dig into the settings manually.

Main instruments:

1. Master of Optimization (Settings) → Special opportunities → Optimization wizard) – analyzes the system and suggests clearing the cache, closing background applications and removing unnecessary files» APK-file.
2. Memory cleanup (Settings) → Memory – shows which applications take up the most space and allows you to delete cache or data.
3. Battery and performance (Settings) → Battery and performance) – you can turn on the energy saving mode or select a performance profile (Balanced, Energy saving, Performance).

It is important to understand that standard tools MIUI They don't solve all the problems:

• 🚫 Disable system applications (Mi Browser, Mi Video, GetApps) that cannot be removed without root rights.
• 🚫 Optimize the autoload of applications (many programs run when you turn on your phone, even if you don’t use them).
• 🚫 Fix errors in Google Play Services that often cause battery discharge.

💡

If after using the “Master of Optimization” smartphone still brakes, check the list of autoloadable applications in Settings → Annexes → Autoboot. Turn off everything except messengers and system services.

Manual optimization: cleaning memory and cache

The most noticeable effect is manually cleaning up unnecessary files, starting with cache, which is the temporary data that applications store to speed up work, and over time, the cache grows to several gigabytes and begins to slow down the system.

How to clear the cache:

1. Go to Settings → Memory → Memory Cleanup.
2. Click the app cache and confirm the cleanup.
3. For deep cleaning, use the Warehouse. → Application data where you can delete the cache for each application separately.

But the cache is just the tip of the iceberg, and there's a lot more space.

• 📁 Residual files – data from remote applications (remain in folders) /Android/data and /Android/obb).
• 📸 Duplicate photos and videos — MIUI Often creates copies when editing or backing up.
• 📄 Downloads – Download folder clogged with old ones APK, PDF and other files.

To find and remove duplicates, use third-party tools like Files by Google or CCleaner, which analyze the storage and suggest removing unnecessary files. → Memory. → Memory analysis, but less accurate.

Battery Optimization: How to Increase Your Time

One of the main reasons for fast battery discharge in Xiaomi is the background activity of applications and system services. Even if you do not use the program, it can expend charge on:

• 🔄 Updating content (social networks, news applications).
• 📡 Location tracking (maps, fitness trackers).
• 📶 Synchronization of data (mail, cloud services).

How to optimize battery consumption:

1. Limit autoload: Settings → Annexes → Autoboot – disable everything except messengers and critical services.
2. Set up the battery mode: Settings → Battery and productivity → Battery mode – choose Energy Saving or Super Energy Saving (the latter disables background activity of almost all applications).
3. Disable unnecessary services: Settings → Google → Google services → Advertising → Disable Advertising Personalization Settings → Confidentiality → Special permits → Deactivate "Auto-start authorizations"

Pay special attention to system processes MIUI:

• 🔍 com.miui.analytics – collects data for analytics (you can disable via ADB).
• 📊 com.xiaomi.midrop – file transfer service over Wi-Fi Direct (if you do not use – disable).
• 🎯 com.miui.systemAdSolution – responsible for advertising in system applications.

⚠️ Note: Disconnecting system processes through ADB It can lead to unstable work. MIUI. Before changing the settings, create a backup copy of the data!

Speeding up work: disabling animation and unnecessary processes

If Xiaomi’s smartphone is slow to open apps or “freeze” when scrolling, the problem may lie in:

• 🎭 Interface animations — MIUI Uses smooth transitions that load the processor.
• 🔄 Background activity – applications consume resources even in a folded state.
• 🗑️ Fragmented memory – especially relevant for eMMC devices (e.g. Redmi) 9A or POCO M3).

How to speed up work:

1. Turn off animation: Settings → The phone. → Version. MIUI (7 times to click to turn on the developer mode) Settings → Additionally. → For developers → The scale of the window/transition animation (select) 0.5x or off)
2. Limit background processes: Settings → Additionally. → For developers → Process limit (select "Maximum 2 process in the background")
3. Use lightweight alternatives – replace standard apps MIUI For example, a Nova Launcher instead of a Nova Launcher. MIUI Launcher, Google Photos instead of Xiaomi Gallery).

For devices with eMMC drives (most budget models), it is useful to defragment. SD Maid (root rights required) or manually:

1. Transfer all files from internal memory to PC.
2. Perform a reset to factory settings (Settings → About phone → Reset settings).
3. Return the files back, which will overwrite the data and reduce fragmentation.

💡

Disabling animation and limiting background processes gives performance up to 20-30%, especially on weak smartphones (for example, Redmi). 8A or POCO C31).

Optimization MIUI: shutdown of advertising and data collectors

One of the main claims to MIUI — And it's integrated advertising and analytics, and it's not only annoying, it's also frustrating:

• 📊 CPU loading – constantly sending data to Xiaomi servers consumes resources.
• 🔋 Battery discharge – background activity of advertising services can eat up to 10-15% of the charge per day.
• 🌍 Spending traffic – especially for users with a limited Internet package.

How to turn off advertising and analytics:

1. Through settings MIUI: Settings → Confidentiality → Advertising → Disable "Personalized recommendations" Settings → Confidentiality → Special permits → Disable AutoRun Permissions for Mi Browser and GetApps

After disabling advertising services, you will notice:

• ✅ Reduce battery consumption by 5-10%.
• ✅ More seamless interface work (especially in Mi Browser and GetApps).
• ✅ Absence of banners in system applications (for example, in Security or Themes).

If you don't want to mess with ADB, You can use the App Ops app (root required), which allows you to manually disable permissions for system processes.

When Optimization Doesn't Work: Radical Measures

If after all the manipulations, the Xiaomi smartphone continues to slow down, perhaps the problem lies deeper:

• 🛠️ Battery wear – with a capacity below 70%, the device begins to limit performance.
• 🔧 File system damage – often occurs after incorrect updates or resets.
• 🦠 Viruses or malware – some applications disguise themselves as system and load the processor.

Radical solutions:

1. Factory reset — deletes all data, but returns the system to its original state. → The phone. → Resetting settings.
2. Fastboot Flipboard is relevant if MIUI It's unstable. You'll need a PC, a Mi Flash Tool, and the official firmware from Xiaomi.

⚠️ Warning: Fastboot flashing or custom software installation will void warranty and may lead to a device blink. Use these methods only if you are confident in your actions!

Before taking radical measures, check:

• 🔋 Battery status via #4636## (in the menu).
• 🛡️ Viruses with Malwarebytes or Dr.Web Light.
• 📡 Network signal quality – weak signal causes module Wi-Fi/4G work at the limit, which drains the battery.
