Fixed apps in Xiaomi Redmi: purpose, configuration and secrets of use

Xiaomi Redmi smartphone owners often encounter the term “fixed apps” in the system settings, but not everyone understands what it means and how it affects the operation of the device. MIUI, And unlike conventional applications, fixed applications get priority in the background, which can both speed up their launch and increase battery consumption.

In this article, we will discuss in detail what are fixed applications in Redmi, how they differ from blocked or fixed, what are the benefits and risks of using them. You'll learn how to set this setting up for different scenarios, from saving charge to maximum performance in games. MIUI, which are not written in the official instructions, but which can significantly improve the smartphone experience.

What are fixed applications in Xiaomi Redmi: a technical explanation

Fixed applications (in English - pinned applications) are programs that the system uses. MIUI It gives you a special status in resource management, and unlike standard applications that can be downloaded from RAM when you don't have enough resources, those that are fixed stay active in the background, even if you haven't used them in a long time. This mechanism is implemented through ActivityManager – the Android component responsible for the allocation of memory between processes.

Technically, fixing works through two key parameters:

• 🔹 Process Priority: Fixed applications gain value IMPORTANCE_FOREGROUND or IMPORTANCE_VISIBLE, prevents them from being closed by the system.
• 🔹 Blocking battery optimization: MIUI excludes such applications from the list of programs for which aggressive energy-saving algorithms are used.
• 🔹 Memory backup: The system allocates a fixed amount of RAM (usually 100-300 MB per application) that cannot be used by other processes.

It’s important to understand that anchoring is not the same as fixing an app in multitasking (when you pinned down a card in a review of recent apps). The fixing works at the system level and persists even after the device is restarted, whereas the fixation in multitasking is reset when cleaned. RAM or rebut.

Differences between fixed applications and blocked and fixed applications

Many users confuse fixed applications with other similar functions in the MIUI. Discuss the key differences:

The critical thing is that attaching an application automatically adds it to the battery whitelist, but not vice versa. This means that if you manually add a program to the power saving exceptions, it can still be unloaded from memory when resources are scarce, while securing it guarantees both RAM and no battery restrictions.

⚠️ Attention: On devices with MIUI 14+ App fixing may conflict with the Deep Optimization function (included in Settings) → Additionally. → If this option is active, the priorities of the fixed programmes may be ignored.

Why you need fixed applications: pros and cons

Using fixed applications has a few key benefits, but it also has a downside. Consider the balance of pros and cons:

• ✅ Instant launch: apps open without delay, as they are already loaded into memory, especially in instant messengers (Telegram, WhatsApp) and social networks.
• ✅ Preserve status: For example, Spotify music will not be interrupted if you switch to another app, and the chat in Viber will remain open.
• ✅ Stability of notifications: fixed messengers receive push notifications without delay, even if the device has not been used for a long time.
• ✅ Optimization for games: In Redmi with Snapdragon or Dimensity chipsets, securing a gaming client (like Genshin Impact) reduces friezes when switching between applications.

However, there are also significant shortcomings:

• ❌ Increased battery consumption: each fixed application consumes up to 5-15% of the additional charge per day (depending on the model).
• ❌ RAM boot: on devices with 4-6 GB of memory fixing 5+ Applications can lead to lags when multitasking.
• ❌ Overheating: On the Redmi Note series with Helio processors, fixing heavy apps (such as Facebook or TikTok) can raise the temperature of the chipset by 5-10°C.
• ❌ Conflicts with Greenify: If you use processes hibernation apps (like Greenify), the fixed programs may ignore their limitations.

Only attach applications that are critical to your use case. For most users, 2-3 fixed programs are enough. + music player).

How to fix the application in Xiaomi Redmi: step-by-step instructions

The process of fixing applications differs depending on the version MIUI. Below is a general guideline that is relevant to MIUI 12–14:

1. Open Settings → Applications → Application Management.
2. Select the application you want to secure (e.g. Telegram).
3. Slip on the item Battery (in some versions - Battery consumption).
4. Activate the “App Lock” switch (or “No Limits” in older versions).
5. Confirm the action in the dialog box (the system will warn you about a possible increase in battery consumption).

For MIUI 14 on Redmi Note 12 and newer path may be different:

Settings → Applications → Permissions → Auto Run → [select application] → Secure

To check which apps are already attached, go to:

Settings → Battery → Battery settings → Applications selection

Here in the "Accessed" section will be a list of active programs.

⚠️ Note: On some models (Redmi) 10A, Redmi 9C) The fixing function can be hidden. To unlock it, activate Developer Mode (7 taps by build number in Settings). → About the phone) and turn on the debugging option USB. After that, the “Secure” item will appear in the battery settings.

The hidden capabilities of the fixed applications in MIUI

Besides the obvious features, the fixed apps in Xiaomi Redmi have a few hidden features that few people know about:

• 🔍 Priority Network Access: Log-in programs get more traffic when signal is weak (useful for Google Maps on trips).
• 🔍 Fast sync: For example, Gmail or Outlook updates email in the background every 5 minutes instead of the standard 15.
• 🔍 Ignoring Data Saver restrictions: even if the traffic saving mode is enabled, the fixed applications will use the mobile Internet without restrictions.
• 🔍 Concealment from cleaning RAM: when manually cleaning the memory (the “Clear” button in the application review) the fixed programs are not closed.

On devices with MIUI 13+ and Snapdragon chipsets 7xx/8xx Appendixes also affect the:

• 🎮 Game performance: fixed Call of Duty Mobile or PUBG priority GPU, reduces friezes.
• 📱 Widgets: Widgets of fixed applications (such as weather or calendar) are updated more often.
• 🔊 Audible notifications: fixed messengers can play notification sounds even in Do Not Disturb mode».

Another little-known trick is the security lock-in.

1. Open the Security app (Security).
2. Go to Optimization. → Auto-start.
3. Select the application and activate “Secure” in additional settings.

This method works even on models where the function is hidden in the basic settings.

How to unplug the application and what will happen if you do it

If you decide to remove the application from the fixed ones, you can do this in two ways:

1. Through battery settings: Settings → Battery → Battery setup → Choice of applications → [swipe left on appendix]
2. Through the app menu: Settings → Annexes → [select] → Battery → Unlock

After detachment:

• 📉 The application will be unloaded from memory when there is a lack of resources.
• ⚡ Battery consumption will decrease by 3-8% (depending on the program).
• 🔔 Notifications may be delayed (up to 1-2 minutes).
• 🔄 The next time you run the app, it will open longer (1-3 seconds).

⚠️ Attention: Redmi with MIUI 12 and below, unplug system applications (for example, Mi Video or Mi Music) can cause malfunctions in the media player, in which case, resetting the application settings (Settings) will help. → Annexes → [choose] → Warehouse → Clear the data).

If the app starts to work unstable after unplug (for example, Instagram does not update the feed), try:

1. Clear the app cache.
2. Reset the device.
3. Temporarily fix it again for 1-2 days to reset the background restrictions.

Optimal settings of fixed applications for different scenarios

The number and type of applications attached depend on your smartphone usage style. Consider the optimal configurations for scenarios:

For Redmi users with 4 GB of RAM or less, it is recommended to attach no more than 2-3 applications.+ GB (e.g. Redmi) K50 Or the Redmi Note 12 Pro.+) This number can be increased to 5-6 without the risk of lag.

💡

If you use Xiaomi Redmi with custom firmware (like Pixel Experience), app attachment may not work, in which case use the Magisk module called App Systemizer to prioritize the programs you want.
