Xiaomi phone is slow: the complete guide to acceleration

The situation when the once-quick smartphone suddenly turns into a sluggish device is familiar to every owner of Xiaomi equipment. Users often face delays when switching between applications, a long menu opening and sudden interface freezes. This does not always mean that the hardware resource is exhausted and it is time to change the device.

In most cases, the problem lies in software conflicts, overflow of system storage or the features of the MIUI shell and the new HyperOS. Android has the property of accumulating temporary files that eventually begin to slow down the process of reading and writing data. Understanding the reasons allows you to effectively fight lags without losing personal data.

There are a number of proven methods that help to restore the responsiveness of even models of the past, and we will look at both standard cleaning tools and hidden developer settings that are available to everyone, and it is important to act consistently so that the system does not disrupt the stability of the system.

Diagnosing the causes of low productivity

Before we take any drastic measures, we need to understand what is loading the processor. Often the culprit is one particular application that is not working properly in the background. Owners of Redmi and Poco may notice that the phone is warming even in plain, which is a sure sign of hidden software activity.

System resources can run out due to memory fragmentation or crowded cache. RAM is filled with residual processes that do not close automatically. This is especially true for models with 4 GB of RAM or less, where every megabyte counts.

⚠️ Warning: If the phone heats up at the top of the case without an active load, this could indicate battery wear or power controller issues, not just software failures.

To make an initial assessment of the condition of the device, you should use an integrated analyzer to show which programs consume the most power and resources of the processor, sometimes you just need to remove or update the problematic software to make a difference.

Error log analysis can reveal recurring service failures; users don’t need to be programmers to notice obvious anomalies in a gadget’s behavior; and a sharp drop in autonomy often goes hand in hand with a drop in performance.

Cleaning Storage and Optimizing Memory

Overcrowded internal storage is one of the most common reasons why the phone is slow. 10-15% And the Android system uses free space as a buffer for temporary operations, and its absence leads to brakes.

Use the built-in Security app to clean up your trash quickly, but for deep cleaning, you'd better manually analyze folders of instant messengers like Telegram or WhatsApp, which can take up tens of gigabytes, saving all the photos and videos you've viewed.

• 🗑️ Remove downloaded files from the Download folder that are no longer needed.
• 📸 Transfer photos and videos to cloud storage or to your computer.
• 📱 Clear the cache of heavy applications through the settings in the App section.
• 🔄 Remove unused games and programs that take up space.

The.thumbnails folder, which stores thumbnails of images, can grow to several gigabytes over time, is safe to clean, and the system will recreate it as needed, but in smaller volumes.

Remember to check the Android/data folder, where some apps store their cached data. Cleaning up here may require re-authorization in some services, but will free up a significant amount of space. Regular storage maintenance prolongs the life of the drive.

Customization of animations and MIUI interface

The visual smoothness of a MIUI or HyperOS shell is often created by animations. If the phone is slow, turning off or accelerating these effects will create the illusion of speed. It will not add processing power, but eliminate the delays in transitions.

To access these settings, you need to activate the developer menu. Find About Phone in the settings and quickly press 7 times on the MIUI version. After that, a new section will appear in the advanced settings.

In the developer menu, find a subsection related to drawing, and here we're interested in three parameters that are set to 1x by default.

Changing these parameters makes the interface more twitchy, but significantly responsive. For older models, it is often the only solution that makes you comfortable using your smartphone. Experiment with values to find a balance between speed and visual pleasantness.

💡

Try setting a 0.5x value instead of completely shutting down – this will keep the visual link of actions, but will speed up the work.

Autostart and Background Process Management

Xiaomi’s aggressive background application policy sometimes fails to allow unnecessary programs to hang in memory, consuming not only the battery, but also the processing power of the processor, and auto-start control is a key step in optimization.

Go to the battery settings and find AutoStart Apps. Disable all programs that don't need to start immediately after you turn on your phone. Social networks and instant messengers are best left on to keep notifications from missing, but games and stores can be safely blocked.

⚠️ Warning: Disabling system processes in this menu can cause the phone to run unstable.Block only apps you installed yourself.

Also, check the energy saving settings for each application separately. Set "No Limits" mode only for those programs that must run in the background constantly. For others, select the Saving Power mode, which allows the system to unload them from memory when inactive.

There's a hidden feature in the developer menu called MIUI Optimization.It disables app permissions and changes the system's behavior, making it more like pure Android.This can help if crashes are caused by shell conflicts.

Resetting and system update

If software methods fail, there may be critical bugs in the system. Updating to the latest firmware version often contains performance patches. Check for updates in the About Phone section.

A radical but effective method is a factory reset. Be sure to back up your data in the Mi Cloud or on your computer before doing so, a step that removes all user data and puts the phone back out of the box.

The discharge process is as follows:

1. Go to Settings. → The phone.
2. Choose Reset settings.
3. Press Erase All Data.
4. Confirm the action with the unlock password.

You don't have to install hundreds of applications right after you're reset, you can try to run a clean system for a couple of days, if the lags are gone, it's because it's a software junk or a software conflict, and you can slowly bring the apps back to identify the culprit.

💡

Hard Reset eliminates 90% of software performance issues, but takes time to reconfigure the device.

Hardware limitations and wear of the device

Remember, any electronic device has a lifespan, and if the phone is more than 4-5 years old, its components may have worn out physically, and in particular, the degradation of flash memory leads to a drop in read and write speed, which directly affects the performance.

Overheating is another factor that causes trotting (forced processor frequency reduction) If the phone is constantly hot, it will work slowly to keep it from burning. Check the condition of the thermal paste and the density of the case if you have repair skills.

Signs that it is time to change or carry your phone to the service:

• 📉 The phone hangs even on the desktop without running applications.
• 🔋 The battery is discharged for 2-3 standby.
• 💾 Apps crash with “not enough memory” error, even though there is a place.
• 📱 The screen responds to touches with a long delay.

In some cases, flashing the device through the computer using the Mi Flash Tool helps, allowing you to install a clean version of the system without having to upgrade "over the air" that may be damaged, but this requires certain technical skills.
