Why Xiaomi is dumbing down: causes of lags and ways to accelerate

Owning a Xiaomi smartphone is often a compromise between cutting-edge performance for reasonable money and specific system behavior. Users often face a situation where a once-quick device suddenly starts to hang, open apps for a long time or chaoticly close background processes.

At the heart of the problem is the complex architecture of the MIUI shell or the new HyperOS, which requires fine-tuning to work comfortably. Understanding the deep workings of the Android operating system in conjunction with proprietary add-ons allows you to eliminate most performance problems without having to reset to factory settings. In this article, we will discuss in detail the technical aspects that make the device work slower.

The bulk of the problems are unoptimized processes, overconsumption of resources, and aggressive energy-saving policies. Systemic conflicts can occur even on new models if you ignore regular maintenance. Let's look at specific steps that will bring your gadget back to its old apex.

Aggressive memory optimization and background processes

One of the main reasons Xiaomi is slowing down is its overly aggressive memory management policy: its engineers deliberately limit the number of applications running simultaneously to prolong battery life. However, in the pursuit of saving charge, the system often kills the processes it needs, forcing the processor to restart them every time it calls, creating the effect of slowing the interface down.

MIUI Optimization often interprets active background services as a stability threat. When you switch between heavy applications, the system unloads them from RAM, and when you return, the program is completely rebooted. This creates a feeling of a "heavy" interface. To solve the problem, you need to manually set priorities for frequently used programs.

💡

Turn on the option "Memory Extension" in the settings, if the smartphone model supports virtual increase in RAM, this will reduce the frequency of unloading background applications.

To minimize the impact of this factor, the following actions should be performed:

• 🚀 Go to the battery settings and select Performance mode for games or heavy tasks.
• 🚫 Turn off automatic memory cleaning in the Security menu so that the system does not interfere with your work.
• ⚙️ In the "Applications" section, find the desired program and in the "Autostart" paragraph, allow it to start with the system.

It is important to understand that completely disabling memory optimization can lead to faster battery discharge. The balance between speed and autonomy is a key point of setting, and the user must determine for himself what is more important for him at the moment: maximum response speed or duration of operation without recharging.

Internal storage overflow and data fragmentation

The speed of any modern smartphone depends on the speed of reading and writing data to the internal drive. When free space on the disk ends, the write speed drops catastrophically, this is due to the peculiarities of flash memory, which requires free space for even distribution of data and conducting service operations.

If you have more than 85% of your internal memory, you are guaranteed to experience interface lags, a long gallery opening, and hanging when installing updates. Android uses free space as a buffer for temporary files and cache. The absence of this buffer causes the processor to wait for disk operations to be completed, which is perceived by the user as “stupid”.

To diagnose the state of the storage, use a standard cleaning tool or third-party utilities. Pay attention to messenger folders, which often grow to giant sizes due to stored media files. It is also worth checking the Download folder, where old APK installation files may have accumulated.

Regularly auditing files is recommended:

• 🗑️ Remove unnecessary screenshots and duplicate photos that take up space.
• 📦 Transfer archived videos and documents to a cloud server or computer.
• 📲 Clear the cache of heavy apps like Telegram, YouTube and browsers through settings.

⚠️ Warning: Don’t use the dubious accelerator apps from Play Market that promise to clear memory with a single click, consume resources themselves and often contain ads, making things worse.

Impact of MIUI Advertising and System Services on Performance

One of the features of Xiaomi’s ecosystem is that it has built-in advertising and a lot of pre-installed services that run in the background, and MSA (MIUI System Ads) and other components are constantly accessing the network, checking the relevance of ad units and collecting usage statistics, which puts additional strain on the processor and communication channel.

Even if you don't see pop-ups, data collection and analytics continue to consume computing resources. On budget models with less powerful processors, this becomes noticeable, because every percent of the CPU's power counts. Disabling unnecessary services is a must-do step to improve system responsiveness.

To reduce the load, perform the following settings:

• 🔒 Turn off personalization of ads in your Mi Account settings.
• 📉 In the menu "Advanced settings" find the item "Receive recommendations" and deactivate it.
• 🛑 Remove or freeze pre-installed apps that you do not use (e.g. Booking, AliExpress, if built-in).

When you turn off the ad modules, you'll notice that the interface responds faster and traffic is more economical, and this is especially true for users who prefer minimalism and cleanliness, and the digital noise of constant service requests really slows down the device.

Problems with animation and visual effects

Xiaomi’s visual smoothness is heavily influenced by animation rendering. MIUI 12/13/14 and HyperOS shells are packed with complex visuals that require significant graphics accelerator resources. On mid- and low-end devices, rendering these effects can cause micro-freezes, especially when folding applications or switching between desktops.

Decreasing the quality or speed of animation is a proven way to make the interface more visually responsive. It doesn't increase the actual power of the processor, but it reduces the waiting time for transitions to complete, creating a sense of instantaneous response to touch. There are tools on the developer menu for this.

To access hidden settings, you need to activate the developer mode:

1. Go to Settings. → The phone.
2. Quickly press 7 times on the MIUI version (or OS version).
3. In the menu that appears Additional → For developers, find the section "Drawing".

So here you're interested in three things: "Window animation," "Change animation," and "Duration animation." Set 0.5x for comfort balance or Off for maximum speed, and zooming in on these things will immediately affect your subjective perception of smartphone performance.

Comparison of productivity optimization methods

There are many ways to try to speed up a smartphone, but not all of them are equally effective and safe. Some methods give instant but short-term results, others take time but provide stability. Below is a table comparing the main approaches to solving the problem of lag.

As you can see from the table, the most radical but effective method is a complete reset, but before you resort to it, you should try software methods of setting up. A comprehensive approach that combines cleaning the storage and setting up animations solves the problem in 80% of cases without losing data.

Wipe Data is the only solution that is guaranteed to eliminate software errors and update conflicts.

Processor overheating and trottling

Modern processors installed in Xiaomi smartphones are high performance, but under intense loads are prone to heating. When the temperature reaches critical values, the protective mechanism is triggered - trottling. The processor artificially lowers its clock frequencies to cool down, which leads to a sharp drop in FPS in games and lags in the interface.

Often, overheating is caused not only by heavy play, but also by the trivial use of navigation with the screen on in the bright sun, or by working on a 4G/5G network with a weak signal.

To avoid trolling, it is recommended:

• 🌡️ Remove the case during games or charging, if it does not remove heat well.
• 📶 Switch to the "Aviapolet" mode in areas of uncertain network reception.
• 🔋 Do not use your smartphone during fast charging for heavy tasks.

⚠️ Warning: If the smartphone is warming and braking even in a simple (desktop), this may indicate a malfunction of the battery or cooling system.
