How to speed up Xiaomi tablet: from cache cleaning to deep optimization

Xiaomi tablets are some of the most popular devices on the market due to their price-performance ratio. However, over time, even powerful models like the Xiaomi Pad 6 Pro or Mi Pad 5 start to slow down: apps open for a long time, animations twitch, and the system reacts with a delay. The reasons can vary from overloaded memory to outdated firmware. In this article, we will discuss 10 working ways to speed up the Xiaomi tablet, starting with simple settings and ending with deep optimization.

It's important to understand that the brakes aren't always hardware-related, and more often than not, software is to blame: background processes, junk files, or incorrect settings. We won't advise you to buy a new device, instead, we'll show you how to get back to speed without losing data and complex manipulations. If your tablet has become slower after updating MIUI or installing new applications, the following methods will help solve the problem.

1. Cleaning up cache and junk files

The first thing to do when you slow down a tablet is to clear the app cache and the system temporary files. The cache speeds up the loading of frequently used data, but over time it accumulates and takes up gigabytes of memory, slowing down the system. MIUI has a built-in tool for this task.

How to clear the cache:

• 📱 Go to Settings. → Annexes → Application management.
• 🔍 Select an app that slows down (like Chrome or Facebook).
• 🧹 Click Clear cache (do not delete data, otherwise you will lose logins!).
• 🚀 For mass cleaning, use the settings → Memory. → Cleanup.

For deep cleaning of garbage, the Security app (built into MIUI) or third-party utilities like CCleaner will do. However, be careful: some cleaners delete useful files, which can lead to failures. On Xiaomi tablets with MIUI 14+, the built-in cleaning works more efficiently than third-party programs - use it first.

💡

If after cleaning the cache, the application began to work worse (for example, it loads longer), restart the tablet - the system will restore the necessary temporary files.

2. Optimization of background processes

MIUI is known for aggressively controlling background processes, but sometimes it plays against the user. If a Xiaomi tablet slows down when multitasking, maybe the system is forced to close the apps you need.

How to turn off unnecessary background processes:

• ⚙️ Go to Settings. → Battery and productivity → Battery management.
• 🔋 Select the Apps Select and mark the ones that should work in the background (e.g., instant messengers).
• ❌ Turn off auto-start for unnecessary apps in Settings → Annexes → Auto-start.
• 📉 B Settings → Special facilities → Accelerate the system and enable the optimisation option MIUI (readily MIUI 13+).

On tablets with MediaTek (such as the Xiaomi Pad 5), background optimization works differently than on Snapdragon. If after the changes there are lags, return the settings to the factory settings - perhaps the system itself is better allocates resources.

3. Update MIUI and firmware

The outdated version of MIUI is one of the main reasons for the slowdown. Xiaomi regularly releases updates that optimize system performance, fix bugs and improve compatibility with new apps. If your tablet hasn't updated in a long time, this could be the key to solving the problem.

How to update MIUI:

1. 🔄 Go to Settings. → The phone. → Updating the system.
2. 🔍 Click Check Updates and wait for the search.
3. 📥 If a new version is available, download it (preferably via Wi-Fi).
4. 🔄 After installation, restart the tablet.

If the automatic update doesn't work, you can manually install the firmware through Recovery or Fastboot. However, this method requires experience - wrong actions can lead to a device blink. OTA-update.

4. reset to factory settings (Hard Reset)

If the Xiaomi tablet is slowing down even after cleaning the cache and updating, the last chance to return performance is a full reset. This method deletes all data, so make a backup before the procedure.

How to reset the tablet to factory settings:

• 📲 Go to Settings. → The phone. → Resetting settings.
• 🔄 Choose to erase all data and confirm the action.
• 🔐 After the reboot, the tablet will be like new - you will need to re-configure.

Resetting helps in 80% of cases when the brakes are caused by software failures, but if the problem is in hardware (wearing out memory, overheating the processor), this method will not have a long-term effect. After reset, do not install all the applications at once - add them gradually to identify the "braking" software.

5. Optimization of memory and storage

Lack of space on the internal drive is a common cause of lag. Xiaomi recommends leaving at least 10-15% of free space for stable operation of the system. If the memory is filled to the end, the tablet begins to “brake” when writing new data.

How to make room:

To analyze the occupied space, use the built-in Settings → Memory menu. Pay attention to the System Data section - if it takes up more than 10 GB, this is a sign of debris, in which case resetting or manual cleaning through ADB will help.

💡

If the tablet is slowing down when you write files (for example, when you shoot a video), the problem is definitely a lack of memory or wear of the drive. SD-If the lags are gone, it is time to change the internal memory.

6. Disable animation and visual effects

MIUI is known for its beautiful animations, but they consume CPU and memory resources. Disabling unnecessary visuals can significantly speed up the work of the tablet, especially on weak models like the Xiaomi Pad 4 or Mi Pad 3.

How to turn off animation:

1. 🛠️ Turn on Developer Mode by pressing the Version 7 times MIUI In Settings → The phone.
2. 🎨 Back to Settings → Additionally. → For developers.
3. 🖥️ Find the settings: The scale of the window animation → Disable Transition Animation Scale → Disable the duration of animation → No animation.

You can also switch to the lightweight MIUI theme:

• 🎨 Go to Settings. → Screen. → Topics.
• 🔍 Choose a theme marked Light or Basic.
• 🖼️ Turn off live wallpaper in Settings → Wallpaper.

These changes will make the interface less beautiful, but noticeably faster, especially for tablets with 2-3 GB of RAM, where every megabyte counts.

7.Verification for viruses and malware

Viruses and ad units are another reason for the brakes: they consume resources in the background, show annoying ads and can steal data. Xiaomi builds antivirus into Security, but it doesn't always detect all the threats.

How to check the tablet for viruses:

• 🛡️ Open the Security app (shield icon).
• 🔍 Click Scan and wait until it is completed.
• ⚠️ Remove the detected threats and restart the tablet.
• 🔒 For a deep check, use Malwarebytes or Dr.Web Light.

If you have brakes left after scanning, check the list of installed applications, remove suspicious programs (especially those that ask for a lot of permissions).

• 🎮 Unofficial launchers and games from unknown sources.
• 📺 Apps for “acceleration” or “cleaning” (many of them are viruses themselves).
• 💰 Cashback services and programs for “making money».

💡

If the tablet began to slow down after installation APK-A file from the Internet, delete it immediately and scan the system. Many hacked games contain miners that load the processor to 100 times%.

8. Thermopaste replacement and overheating check

If all software methods failed, the problem could be overheating. Xiaomi tablets (especially those with MediaTek processors) are prone to overheating due to poor thermal paste or a dust-clogged cooling system. When heated above 60-70°C, the processor begins trottling (reducing frequency), which leads to lags.

How to check the temperature:

• 🌡️ Install the app CPU Monitor AIDA64.
• 📊 Run a performance test and watch the temperature chart.
• ⚠️ If the temperature is greater than 75°C in simple, requires cleaning or replacement of the heat paste.

For self-replacement of thermopaste:

1. 🛠️ Disassemble the tablet (you need a plastic mediator and a screwdriver).
2. 🧴 Remove the old paste with alcohol and apply a new one (such as Arctic) MX-4).
3. 🔧 Check the cooler (if any) for dust.

⚠️ Warning: Disassembling the tablet is not warranty! If you are not sure of your abilities, contact the service center. On Xiaomi Pad 6 and newer models, glue is used, and you need a hair dryer to open it.

After replacing the heat paste, check the temperature under load (for example, in Genshin Impact) If it does not exceed 65-70 ° C, the problem is solved. Otherwise, you may need to replace the battery or cooling plate.
