Xiaomi phone is dumbing down: the complete guide to acceleration

Suddenly slowing down a smartphone is one of the most annoying problems faced by owners of Xiaomi, Redmi and Poco devices. Yesterday the interface flew, and today the opening of the gallery turned into torture, and applications fly out at the most inopportune moment. This does not always mean that it is time to buy a new gadget, often the cause lies in software failures or overcrowded storage.

The Android system that powers the MIUI or HyperOS shell tends to accumulate temporary files and cache, which can lead to performance declines over time. It’s important to understand that your phone’s hardware may be quite functional, and the brakes are caused by a banal lack of resources to handle current tasks. In this article, we’ll look at specific steps to reanimate your device.

Before you panic and bring your device to service, you should try a number of software methods that return speed 90 percent of the time. We'll look at both standard settings and deeper optimization methods available to the average user. Removing system updates or resetting to factory settings is often the only way to revive a device after a failed update.

Diagnosis: why the smartphone began to work slowly

The first step should always be to understand the cause of the problem. If a Xiaomi phone starts to glittle, it may be a consequence of background processes that consume RAM. Often users install applications that are prescribed for autoboot and prevent the processor from resting, constantly loading the cores even in standby mode.

Another common cause is overheating, and when the body or internals get above normal, the system forces the processor to lower its clock speed to avoid damage, a phenomenon called trottling, which manifests itself in the form of jerks and friezes in the interface, and see if your device gets hot while charging or using the navigator.

• 🔥 Overheating of the processor due to a cover or direct sun.
• 💾 Overflowing internal memory, which slows down reading data.
• 📱 An outdated version of firmware with known optimization bugs.
• 🦠 Presence of malware or miners in hidden applications.

⚠️ Warning: If the phone is warming up even in a simple and quickly discharged, perhaps the problem is not in the software, but in the physical wear of the battery or a malfunction of the motherboard.

Also worth noting is the internal storage capacity, where when the space is running out, the system has nowhere to create temporary swap files, which is critical for performance, especially for models with 64GB of storage and less, where the system and applications take up the lion's share of space.

Memory cleaning and garbage removal

The most effective way to speed up your smartphone is to free up disk space. Xiaomi owners often neglect built-in tools, although the Security app is able to clean up cache quite aggressively and efficiently. Go to the storage settings and delete files that are larger than 100 MB if you don't need them.

Special attention should be paid to messengers like Telegram and WhatsApp, which have been accumulating gigabytes of photos and videos for years, which are automatically saved to the gallery. Clearing the cache of these programs through Android settings is often safer and more useful than removing the apps themselves. Just go to Settings → Apps → All apps and find what you need.

Sometimes cleaning the cache through an engineering menu or recovery helps, but for the average user, standard tools are enough. Remember to check the Android/data folder, where the tails from long-deleted games may remain. If the phone stopped responding to touch, it may be the lack of memory that blocks input processing.

Optimization of MIUI and HyperOS settings

Xiaomi’s shells are famous for their functionality, but also for their abundance of animations that can create the illusion of slow work. If the phone is buggy, try turning off or speeding up animations in the developer menu, which will make the interface more visually responsive, even if the hardware power does not change.

To access the hidden settings, you need to activate the developer mode. Press the build number 7 times in the About section. Then a new item will appear in the menu where you can find the animation zoom options, set 0.5x values or completely disable them for maximum performance.

It's also worth checking the advanced memory settings. In modern Redmi and Poco models, there's a function to expand RAM to internal memory. Paradoxically, on older or cheaper drives, this feature can slow down because virtual memory reads faster than physical. Try turning off the memory expansion in the settings and reboot the device.

Update or rollback of the system

Often, the problem is solved by updating the firmware to the current version. Xiaomi engineers regularly release patches that fix optimization errors. Go to Settings → About the phone and click on the system version. If an update is available, install it, saving important data beforehand.

However, the reverse is true: after the upgrade, the phone started to slow down, in which case the new version may be “raw” or simply heavy for your “hardware”. If the lags started immediately after the update, it makes sense to consider rolling back on the previous stable version, although this requires unlocking the bootloader.

⚠️ Warning: rolling back the system or flashing it manually without proper knowledge can lead to a loss of warranty and turn the phone into a brick.

For models with a locked bootloader, the only safe way is to completely reset (Hard Reset), which will delete all data, but return the system to the “out of the box” state, removing all accumulated software conflicts. SIM-memory-card.

Problems with applications and background processes

Some apps can cause conflicts by making Xiaomi's phone freeze, especially heavy social media and gaming, check the battery settings to see which apps consume the most power in the background, and if you see a program there that you don't use all the time, limit its background activity.

Each application has a "Sunset" setting, so make sure that only the messengers and alarms are on, and the rest of the programs don't have to start with the system, because they take up precious RAM, and turning off autostart is one of the most effective ways to speed up an old smartphone.

• 🚫 Turn off auto-start for games and shops.
• 🔒 Check the access rights to the microphone and geolocation.
• 🗑️ Remove apps that haven’t been used for more than a month.
• ⚙️ Reset the settings of Google Play Services apps.

💡

Use the “Lite” versions of apps. For older Xiaomi models, there are lighter versions of Facebook, Instagram, and other services that consume less resources and less CPU load.

Also worth noting is desktop widgets: Live wallpaper and news widgets are constantly updated and consume CPU resources. If the phone is slow, go to static wallpaper and remove unnecessary widgets from the home screen, which will free up the GPU to process the interface.

Radical measures: resetting and reflashing

If nothing works, the last and most reliable method is a full factory reset, which will return the phone to its original state, make sure that the battery is above 50% before you start, and you remember the password from your Mi Account, otherwise activation after the reset will not be possible.

You can start the reset process through the recovery menu. To do this, turn off your phone and press the button combination (usually Volume Up + Power). In the menu that appears, select Wipe Data. Be careful, this process is irreversible and will destroy all photos, contacts and files.

For advanced users, there is a possibility of clean flashing through the computer using the Mi Flash Tool utility, which allows you to install "clean" global or Chinese firmware without unnecessary garbage. However, as mentioned, this requires an unlocked bootloader and carries risks.

💡

Hard Reset eliminates 95% of the software causes of brakes, as it removes all file conflicts and settings accumulated during use.

⚠️ Warning: After the reset, the system will re-index the files and update the applications. 30-60 The phone can run slowly and warm up – it’s a normal optimization process, give it time.
