Why Xiaomi is slowing down: The Complete Guide to Acceleration

Owners of MIUI-based devices often face a situation where once-fast devices suddenly start to work slowly. Xiaomi smartphones are famous for their excellent price-performance ratio, but over time they can demand attention to the system. This does not always mean a breakdown, often due to software conflicts or lack of resources.

To understand why Xiaomi is slowing down, we can analyze several key factors, from overcrowded memory to background processes. In this article, we will examine the mechanics of Android slowdown and propose specific solutions. Optimization takes a little time, but the result is worth it.

Sometimes the problem is that you get a simple overheating or a particular application crash, and understanding how the operating system works in the background will help you prevent lags in the future, and we'll look at both software cleaning techniques and deeper system settings.

Internal memory overflow and its effect on speed

One of the most common reasons Xiaomi is slowing down is the critical filling of internal storage. When the space runs out, Android can't efficiently create temporary files and cache, which leads to a significant decrease in the speed of reading and writing data, which you feel like hanging over.

The system starts to work in a stress mode, trying to carve out space for current tasks, especially on models with 32 or 64 GB of memory, and if the storage indicator is on red, expect performance problems.

⚠️ Note: Do not store heavy video files on your internal drive if you have cloud storage or SD-Memory over 90% can cause system applications to fail and updates to fail.

To check what's taking up space, you have to look at the storage settings, and you often find messenger folders that duplicate media, and you clear those folders and you free up gigabytes of space.

Also worth paying attention to is the size of the app cache: Some programs, such as browsers or navigators, can accumulate hundreds of megabytes of temporary files, and regular cache cleaning helps keep the file system in good shape.

Background processes and inflating of RAM

MIUI shell is known for its aggressive policy of working with background applications, but sometimes it plays a cruel joke. Many running programs consume RAM (RAM), preventing the system from devoting resources to an active window. If you have a model with 3 or 4 GB of RAM, this becomes critical.

Constantly active applications not only eat up memory, but also load the processor, causing heat and trottling, and as a result, the interface starts to twitch, and applications reboot every time they switch, a typical symptom of a lack of RAM.

To combat this, Xiaomi has built-in tool "Memory Extension", which is part of the internal memory for virtual RAM. However, it is worth understanding that the speed of internal memory is lower than that of real RAM, so the performance gain can be insignificant.

• 🚀 Close unused apps through the recent task menu to free up resources.
• 🔋 Turn off auto-run for rarely used programs in battery settings.
• 📉 Reduce the number of widgets on your desktop as they are constantly updated.

It's also important to check which apps have permission to work in the background, often heavy social networks or stores that are constantly hanging in the memory, and limiting their activity significantly unloads the system.

Problems with MIUI animation and visual effects

The visual part of the MIUI shell is beautiful, but it requires resources to render. If the phone starts to brake, the first thing to do is check the animation settings. Excessive graphics can create the illusion of slow work, even if the hardware is coping.

You can find animation zoom options in the Developer menu, and they're 1x by default, and if you reduce them to 0.5x or completely disable them, you make the transitions between the screens instantaneous, and that creates a sense of high performance.

It's also worth mentioning the theme "Dark Theme." It saves power on AMOLED screens, but on some older CPU models, rendering it can cause micro-freezes. Try switching to a lighter theme if you notice strange interface behavior.

Remember that live wallpaper also consumes processor and battery resources. If your Xiaomi is slowing down, replace the dynamic picture with a static image. This is a simple but effective step.

💡

To access the developer menu, go to Settings -> About Phone and quickly click on the MIUI version 7 times. Then the "Developers" option will appear in the advanced settings.

The Impact of System Updates and MIUI Bugs

Often, users notice that the phone starts to slow down as soon as the firmware update is updated, and that's normal: in the first days after the update, files are indexed, databases are rebuilt, and applications are optimized, a process that can take anywhere from hours to days.

However, if time goes by and the lags don’t go away, there may be optimization errors in the new version of MIUI. Xiaomi developers regularly release patches to fix such problems. Ignoring security updates can lead to the system being unstable.

Sometimes the problem is that the old version of the app is in conflict with the new version of Android, which is when you clean up the data of the problem app or reinstall it, and system updates require free space and battery power.

⚠️ Warning: If the phone starts to warm up and discharge quickly after the upgrade, try a full Wipe Data reset, which will delete all data, but is guaranteed to eliminate software conflicts left over from the old version of the system.

There is also the notion of "glutty" global firmware, where some versions of MIUI for the global market come raw, and in such cases, experienced users wait for the stable version to come out or switch to the Chinese version of firmware, which is often updated faster.

Overheating of the device and battery wear

Temperature is the enemy of performance. When Xiaomi's body heats up above comfortable values, the processor resets frequencies to keep it from burning out. This is a phenomenon called trottling. If you play heavy games or shoot 4K video, the brakes are inevitable and are a protective reaction.

But if the phone is warming up in standby mode or on simple tasks, it's a sign of a malfunction, maybe the power controller has failed or the battery has degraded, and the old battery can't give the right current, causing voltage drawdowns and reboots.

You can check the status of the battery through the engineering menu or special diagnostic applications. If the wear exceeds 20-30%, you should think about replacing it. Also, overheating is affected by the case: thick silicone protection interferes with heat removal.

• 🌡️ Remove the case while charging or playing to improve cooling.
• 🔋 Avoid using your phone in temperatures below 0°C or higher than 35°C.
• 🚫 Do not charge the device while it is hot after active operation.

In some cases, the cause of heat and lags is faulty communication module. If the phone is constantly looking for a 4G/5G network in the area of poor reception, it will warm and slow down. Switching to 3G only or On the plane can temporarily solve the problem.

💡

Constant overheating is not just discomfort, it is a signal that the internal components are working at their limit, which reduces the life of the smartphone.

Radical methods: Resetting and flashing

If software cleaning and customization fails, it leaves heavy artillery behind. A full reset to the factory settings (Hard Reset) puts the phone back out of the box, removing all the debris, viruses and misconfigurations accumulated over the years.

Before resetting, make sure to back up your important data to the Mi Cloud or your computer. The process takes 10-15 minutes. Once turned on, you get a clean system that should fly like the first day of purchase.

A more complex method is to flash the device through the computer (Mi Flash Tool), which is true if the phone is booted in the reboot cycle or the system is critically damaged, but for the average user this can be risky.

It's important to choose.
