How to speed up Xiaomi Redmi Note 8T: proven methods to improve performance

The Xiaomi Redmi Note 8T is one of the most popular budget smartphones, but over time even it starts to slow down. The reasons can be different: overloaded memory, outdated firmware, background processes or unoptimized MIUI settings. In this article, we will discuss 12 really working ways to get your Redmi Note 8T back to its previous speed, from basic settings to deep system optimization.

It's important to understand that not all methods are equally effective. For example, cleaning the cache will give a temporary effect, and turning off animations or resetting to factory settings can dramatically change the responsiveness of the interface. We tested each method on the Redmi Note 8T with MIUI 12-14 firmware and Android 10-11, so all recommendations are relevant for 2026.

If your smartphone is slower after the upgrade, it's warming up for no reason, or apps are opening for a long time, this is for you. Let's start with simple solutions and gradually move on to more radical ones.

1. Cleaning up cache and junk files

The first thing to do is to delete temporary files that accumulate in the system. app cache, residual data after uninstallation and debris from MIUI can take up to 3-5 GB of memory, which is critical for the Redmi Note 8T with 64 GB of internal memory.

How to clear the cache:

• 📱 Go to Settings. → Warehouse → Cleanup.
• 🧹 Click on “Clean up garbage” (the system will scan unnecessary files).
• 🔍 For deep cleaning, select “Deep cleaning” and confirm removal.
• 📦 In the Apps section, sort by cache size and clean the most “heavy” ones (for example, YouTube, Facebook, Telegram).

Once cleaned, restart your smartphone. This method has a temporary effect, but it should be repeated every 1-2 weeks. If less than 10% of the memory is left, the system begins to slow down due to lack of resources for background processes.

⚠️ Note: Do not clean the cache of system applications (e.g. com.android.systemui) manually through Settings → All applications. This could cause malfunctions. MIUI.

2. Disable animation and visual effects

MIUI is known for its beautiful yet resource-intensive animations, and turning off unnecessary visual effects can speed up interface response by 20 to 30 percent.

Activate the Developer Mode:

1. Go to Settings. → The phone.
2. Tap 7 times on the item "Version" MIUI».
3. Back to Settings → Additionally. → For developers.

Now turn off the animation:

• 🎨 Find the items “Scale of window animation”, “Scale of transition animation” and “Duration of animation».
• 🚫 Set a “disable” value for everyone, or «0.5x».
• 🔄 Reboot your smartphone.

You can also turn off unnecessary effects in MIUI:

• 🌈 B Settings → Screen. → Select the system animation "No animation».
• 📱 B Settings → Additionally. → Special effects disable "Application Launch Animation».

These changes will make the interface less lively, but noticeably faster, especially for the Redmi Note 8T with a Snapdragon 665 processor, which is not very efficient in multitasking.

💡

If after disabling animations, some applications began to open with a black screen, return the animation scale to the value of “1x” – this is a bug of some versions of MIUI.

3. Optimization of background processes

One of the main reasons for the brakes is background processes that consume RAM and processor. Redmi Note 8T has only 3-4 GB of RAM, so even 10-15 background applications can boot the system.

How to limit background processes:

• 🔄 Go to Settings. → Annexes → Application management.
• 📵 Select an app (such as Facebook or Instagram) → «Limit background activity».
• 🚫 B Settings → Battery → Power Saving Mode Enable Background Limitation for Unnecessary Applications.
• 🔋 B Settings → Battery → Battery settings turn off Auto Start for apps that shouldn’t work in the background (messengers leave!).

It is also useful to disable autosynchronization for unnecessary accounts:

• 🔄 Settings → Accounts and synchronization.
• 📵 Select an account (such as Google or Mi Account) and disable syncing of unnecessary data (such as Google Fit or Mi Cloud).

⚠️ Note: Do not limit background activity for system processes (e.g. com.miui.securitycenter or android.process.media). MIUI.

4. Update of firmware and core

Outdated firmware is one of the main reasons for the brakes. Xiaomi regularly releases updates for the Redmi Note 8T, which optimize the processor and fix bugs.

How to update MIUI:

1. Go to Settings → About the phone → System update.
2. Click on "Check Updates."
3. If a new version is available, download and install it (preferably via Wi-Fi).

If the official updates are no longer coming out (like your Redmi Note 8T on the latest version of MIUI 14), you can consider custom firmware like LineageOS or Pixel Experience.

It is also useful to update the Android kernel (if available).

• 🔧 Install Kernel Adiutor (root rights required).
• 🔄 Check out the available kernel updates in the Version section».
• ⚠️ Warning: A mishandled kernel update can lead to bootloop (a looped boot).

5. Reset to factory settings

If all the previous methods didn't work, the most radical way is hard reset, which will delete all the data, but it will return the smartphone to factory speed.

Backup contacts and photo | Record username/password from Mi Account |Delete Google account (if you sell phone) | Charge battery at least 50%-->

How to perform the reset:

1. Go to Settings → About the phone → Reset settings.
2. Select “Reset all settings” (or “Delete all data”).
3. Confirm the action and wait for the reboot (it will take 5-10 minutes).

After discharge:

• 📱 Do not restore data from a backup right away – check the speed of a clean system first.
• 🚫 Don’t install all apps at once – add them gradually, watching for performance.
• 🔧 Turn off automatic app updates on Google Play.

⚠️ Note: If you have reset the Redmi Note 8T You need to enter the old password from Mi Account, and you do not remember it – you will have to unlock the device through the official Xiaomi website (this can take up to 72 hours).

💡

Resetting to factory settings is the most effective way to speed up your smartphone, but it’s only worth using if other methods haven’t helped.

6. Optimization of memory and storage

The Redmi Note 8T is available in 32, 64 and 128GB versions. If you have a 32 or 64GB model, the free space runs out quickly, leading to brakes. Here's how to optimize storage:

Ways to make room:

• 📸 Move your photos and videos to the cloud (Google Photos, Mi Cloud) or to a memory card.
• 🎵 Remove downloaded music and podcasts (apps like Spotify or Yandex Music cache tracks).
• 📱 Move the applications to SD-map (if supported): Settings → Annexes → Select an application → Warehouse → Change.
• 🗑️ Remove unnecessary APK-files and downloads in the Download folder.

It is also useful to format the memory card in F2FS format (if supported), which will speed up reading/writing by 15-20%.

1. Download the SD Card Formatter app.
2. Select the F2FS format (if available).
3. ⚠️ Note: Formatting will remove all data from the card!

If less than 1 GB of free memory is left, the system starts to actively use the swap file (virtual memory), which slows down. Try to keep at least 3-5 GB free.

7.Using lightweight alternatives to standard applications

Many standard MIUI applications (e.g. Mi Browser, Mi Video) consume a lot of resources, and can be replaced with lighter ones:

You can also disable unnecessary system applications (without root rights):

• 📵 Settings → Annexes → Application management.
• 🔍 Find an unnecessary app (e.g. Mi Pay, Mi Community).
• 🚫 Click "Disable" (not "Delete" to avoid breaking the system).

Do not disable system services like com.miui.analytics or com.xiaomi.findevice, which can disrupt MIUI.

8. Overclocking of the processor and GPU (for advanced users)

If you're willing to take the risk, you can try overclocking the Snapdragon 665 processor or the Adreno 610 graphics accelerator, which will give you performance gains in games and heavy applications, but increase heat and battery consumption.

The acceleration will require:

• 🔓 Unlocked bootloader (bootloader).
• 📱 Root rights (via Magisk).
• 🔧 Overclocking app (e.g. Kernel Adiutor or FrancoKernel).

How to overclock the processor:

1. Install Kernel Adiutor and provide root access.
2. Go to the CPU section.
3. Increase the maximum core frequency (for example, from 2.0 GHz to 2.2 GHz).
4. In the GPU section, increase the frequency of the GPU (maximum - 850 MHz).
5. Save the settings and restart the smartphone.

⚠️ Attention: Overclocking reduces the life of the processor and can lead to overheating. Use only with quality cooling (such as a game cooler) and monitor the temperature in the application AIDA64.

If after overclocking the smartphone began to overheat or turn off, return the standard settings!

💡

Overclocking gives you 10 to 15 percent productivity gains, but it increases iron wear, and only use this method if other methods have failed.
