Xiaomi’s current smartphones have enormous potential, often hidden behind layers of marketing shell and standard factory constraints. Many users don’t even realize that their device can work much faster, more autonomous and more functional if you approach it correctly. Upgrading a gadget is not just a launcher, but a complex work with system parameters, hidden capabilities of the MIUI or HyperOS shell, and deep changes to Android.
In this article, we will look at all the steps in your device’s transformation, from secure settings in the developer menu to advanced methods that require root permissions. You will learn to disable unnecessary system processes that consume resources, and implement features that are not available out of the box.
Before we get into action, we need to understand the current state of the system and prepare the basis for change. Basic optimization starts with analyzing what is slowing down or wasting charge. Resetting all settings to factory before deep modification reduces the risk of file conflicts by 85%. This is a critical step that is often forgotten, hoping for a miracle without full cleanup.
Primary optimization and cleaning of the system
The first step should always be a thorough revision of installed software and autoload. MIUI shell is famous for its aggressive policy of background processes, which sometimes benefits the battery, but often interferes with the normal operation of messengers and navigation. You need to go to Settings → Applications → Autorun and leave only those services that should be alerted instantly.
Then you have to remove or disable the system debris that is preinstalled by the manufacturer. Depending on the region of the firmware (Global, China, EEA), the set of such applications ranges from harmless calculators to intrusive advertising and gaming services, removing these components frees up RAM and reduces the load on the processor during downtime.
☑️ Checklist of primary cleaning
The standard "Clean" button in the Security app does help to free up RAM, but you should not do this too often, as the system will again start filling the cache to speed up the launch of applications. The optimal frequency is once every 2-3 days or when there are clear signs of memory shortage.
⚠️ Note: When removing system applications through ADB Be careful with components that have the words "Framework", "SystemUI" or "Services" in the title, removing them will lead to an endless reboot (bootloop).
Developer menu secrets and hidden functions
For those who want to make the most of the hardware, the developer menu becomes the main tool, and to activate it, you need to quickly click on the MIUI version number seven times in the About Phone section, and once activated, you will be able to access the settings that are hidden from the average user.
One of the most useful features is to scale animations. Standard values often seem to be drawn out, giving the illusion of slow interfaces. Changing the scale of windows, animation transitions and the duration of the animator to a value of 0.5x visually speeds up the system's response to touch, making the interface more responsive and "live".
Hidden codes of the engineering menu
Also on the developer menu, you should pay attention to the limitation of background processes. By default, the system decides how many applications to keep in memory, but you can rigidly set a limit, for example, "No more than 2 processes." This will help on older models with low RAM, although on modern flagships with 8-12 GB of RAM it is better to leave control to the system.
An important parameter is the choice of a graphics driver. If you are an avid mobile gamer, experimenting with driver switching (for example, on System Graphics Driver or Adreno drivers) can give an increase in FPS in certain games, but stability is not guaranteed, and you need to test each option separately.
Accelerating network and improving signal reception
Often the problem with slow internet is not the operator’s tariffs, but the wrong settings of the preferred network type. Xiaomi smartphones can hold on to a weak 4G signal for a long time, instead of switching to stable 3G or, conversely, looking for 5G where there is none. Forced setting of the preferred type of network through an engineering menu or applications like Force LTE Only can make a difference.
To improve call quality and data transfer speed, it is worth checking your carrier's APN settings. Sometimes automatic settings are not optimal. Manually prescribed parameters found on the operator's website or in specialized databases often work more stable, especially in areas of uncertain reception.
The Wi-Fi Assistant feature, which constantly scans available networks, is worth noting. While it is useful for automatic switching, constant network search consumes battery and can cause micro-lags in the communication module. The Settings → Wi-Fi → Wi-Fi Assistant menu recommends turning off automatic open network connectivity and frequency scanning, unless you are in a place with a huge number of access points.
| Network parameter | Standard value | Recommended for speed | Impact on the battery |
|---|---|---|---|
| Type of network | LTE/WCDMA/GSM | LTE Only (if the coverage is good) | Reduces the cost |
| Frequency aggregation | Automobile | Included (Carrier Aggregation) | It's a little bit up. |
| Wi-Fi scanning | Included. | Off (in settings) | It's a marked decrease. |
| Bluetooth scanning | Included. | Turned off (if not necessary) | Decrease. |
Advanced work with ADB and system debris removal
When standard methods are lacking, Android Debug Bridge (ADB) is a powerful command-line tool that allows you to control your smartphone system from a computer at a deep level without having to obtain root rights. It can remove non-removable system applications such as Xiaomi analytics, browser, store themes and other bloatware.
To get started, you need to activate USB debugging in the developer menu and install drivers on the PC. Once the phone is connected, the adb device team checks the connection. Then you can use commands to delete packets. For example, the command to remove the system analyzer looks like this:
adb shell pm uninstall -k --user 0 com.miui.analyticsThis procedure requires caution: Before removing any packet, you need to know its exact name and purpose. There are many lists of "safe to remove" packages for different versions of MIUI, which are compiled by enthusiasts. Using such lists minimizes the risk of turning the phone into a "brick" or disrupting basic functions like calls or a camera.
💡
Use Xiaomi ADB/Fastboot Tools is a graphical shell for ADB that automatically defines the phone model and offers a secure list of apps to remove, which is ideal for beginners.
In addition to removing software, ADB can change hidden system settings that are not displayed in the menu, for example, you can turn off ads in system applications by changing the values in global settings, or force to turn on a dark theme for all applications, even those that do not officially support it.
Castom firmware and obtaining Root rights
The highest degree of pumping is to replace stock firmware with custom (Custom ROM) or obtain superuser rights (Root). Unlocking the bootloader (Bootloader) is the first and mandatory step, which is officially authorized by Xiaomi, but requires a wait of 7 to 168 hours and an account binding.
Once unlocked, tools like Magisk for root access control are available to users, opening the door to installing behavior-changing modules, from system advertising and deep customization to CPU overclocking and audio enhancement. Popular firmware like Pixel Experience or LineageOS can give a second life to older models by upgrading Android to the latest version.
⚠️ Warning: Unlocking the bootloader and installing custom firmware completely voids the warranty on the device, and it also increases security risk: banking applications may stop working without properly configuring root rights concealment (Magisk Hide / Zygisk).
The firmware process always carries risks. Incorrectly selected version of the recovery (TWRP) or interruption of file writing can lead to breakage of partitions. So before starting any manipulations, be sure to make a full backup of important data and make sure that the battery is at least 60%.
Optimizing autonomy and energy management
The final touch of pumping is fine-tuning power consumption. Even after all the optimizations, some processes can eat up charge. MIUI has a Battery feature with detailed statistical reports. Study it to find parasitic applications. It often turns out that some forgotten messenger or game is constantly waking up the phone.
Use power saving modes not only when the battery is down, but also as a constant strategy. Optimized mode limits background activity, but leaves the main functions running. For nighttime, you can set up automatic sleep mode, which turns off data transfer and wakes up the phone only for calls from your favorites.
💡
The combination of disabling ads, properly configuring animations and competent autorun management gives up to 30% performance gains without the need to flash the device.
Although there is no memory effect in modern lithium polymer batteries, periodic calibration of the charge controller (full discharge before switching off and charge up to 100% off) helps the system correctly display the remaining charge and prevents sudden shutdowns at 10-15%.
