The Redmi Note 8T, launched in late 2019 with the Snapdragon 665 processor, was originally marketed as a reliable medium with a great camera and autonomy. However, as time passes and new versions of the MIUI shell come out, owners often experience a marked decline in interface performance, long application launches and periodic slowdowns.
Before resorting to radical measures such as flashing or resetting to factory settings, it is worth exhausting all the possibilities of software optimization. Competent system configuration allows you to return the previous responsiveness even on devices with 4 GB of RAM. In this article, we will discuss effective and safe methods that will help to revive your gadget without losing warranty or risk turning it into a brick.
Optimizing Xiaomi requires a comprehensive approach, from cleaning system debris to changing the depth of animations. Don’t expect miracles if the physical wear of memory is already great, but in most cases the device gets a second wind. Let’s start by analyzing the current state of the system and removing excess ballast.
Analysis and cleaning of system memory
The first step to speed up the Redmi Note 8T is to free up internal storage. When more than 85% of the available volume is filled, the speed of writing and reading data on flash memory drops significantly, which causes lags throughout the system.
Xiaomi’s built-in Security app has a powerful toolkit for initial cleanup, but be careful: Automatic cleanup can remove important cache files that speed up the launch of frequently used programs. It is better to perform deep cleaning manually by removing old downloads and unnecessary installation files. APK.
⚠️ Warning: Don’t use third-party accelerator apps from Play Market that promise instant performance improvements, often using resources in the background and displaying intrusive ads, which only makes the Redmi Note situation worse. 8T.
For effective diagnosis of memory partition occupancy, use the following table to understand which data takes up the most space:
| Type of data | Where to find | Recommendation |
|---|---|---|
| Cash. Telegram/WhatsApp | Settings → Storage | Clean through the application settings |
| Download folder | File manager | Remove old APKs and PDFs |
| Systemic debris | Security Annex | Run a standard cleaning. |
| Photos and videos | Gallery/Google Photos | Move it to the cloud or PC |
Pay special attention to the Android/data folder, where some applications store their temporary files. Regular revision of this section helps keep the system in good shape. If you have more than 20% of the free space after cleaning, you will immediately notice an improvement in the interface.
Optimization of animations and MIUI interface
The visual smoothness of MIUI is often created by long-term animations of transitions between windows. On high-powered flagships, this is not noticeable, but on the Redmi Note 8T, these delays can significantly affect subjective perceptions of speed. Reducing the scale of animation is one of the most effective ways to make a smartphone “live”.
To access these settings, activate the developer mode. Go to Settings → About Phone and quickly click 7 times on MIUI Version. After the message “You became a developer”, go to the menu Additional → For developers. Here we are interested in three parameters: “Scale of window animation”, “Scale of transition animation” and “Scale of animation duration of animation”.
Change the values of these parameters from the standard 1x to 0.5x. This will reduce the opening and closing time of applications by half, creating the illusion of instantaneous response of the system. Some advanced users set a value of 0, but in this case the interface may look twitchy and lack aesthetics.
💡
After the scale of the animations is changed, restart your smartphone so that the changes are applied to all system processes correctly.
It’s also worth disabling Memory Extension if it’s available in your firmware version. Although it uses some of the internal memory as RAM, on low-end processors like the Snapdragon 665, it often backfires, as the system starts to run slower because of the difference in read speeds between conventional and virtual RAM.
Background Process Management and Autoboot
The MIUI shell is known for its aggressive power management policy, but many preinstalled and installed applications are constantly hanging in memory, not only draining the battery, but also pulling the processing power back on the processor, causing brakes in the background.
The first thing you need to do is limit the autoload of apps. Go to Settings → Apps → Auto Run and disable all programs that you don’t need immediately after you turn on your phone. Social networks and instant messengers are best left on to keep notifications from missing, but games and utilities should be banned.
- 🚀 Open “Security” and go to the “Permissions” section» → «Auto-start to block the excess.
- 🔋 In the battery settings, find suspicious apps and select No Limits mode only for important things, limit the rest.
- 🛑 Use Freezing Apps for rarely used programs so they don’t activate without your knowledge.
Another important aspect is the work of advertising identifiers and system advertising services. In the Settings menu → Passwords and security → Authorization and recall can be revoked access to msad (system advertising), which will not only speed up the work, but also remove unnecessary requests to servers.
⚠️ Note: Do not disable system processes with names that contain System, Framework, or «MIUI», If you're not sure what they're supposed to do, it can cause your phone to run unstable or have a cyclical reboot.
Display setting and graphical acceleration
The Redmi Note 8T screen has FullHD+ resolution, which is the standard, but for a CPU it's still 2 million pixels to draw. The Minimum Width (or DPI) option is available on the developer menu. The standard value is usually around 392-411 dpi.
Increasing this value (e.g., to 450-480) will make interface elements smaller, but also reduce the load on the graphics accelerator, as the system will have to render fewer visuals per inch. However, don’t get carried away: too high will make text unreadable, and too low can cause layout problems for some applications.
Should I turn on the GPU Acceleration?
Also check the refresh rate of the screen. in the Redmi Note 8T fixed IPS 60Hz matrix. Make sure that the display settings do not include any image "improvers" that can load the image processor. Turning off the dark theme in some cases can also slightly unload the graphics conveyor, although the image processing processor is not designed to be more difficult. IPS-The energy and resource savings are minimal compared to the AMOLED.
Network settings and the impact on speed
Users often confuse the interface lags with slow Internet. If a smartphone takes a long time to “think” when loading pages or videos, the problem may be network settings. The developer menu has a paragraph “WebView Agent” on it, make sure that it selects the current component, updated through the Play Market, and not the system component, which may be outdated.
Resetting network settings can help if there are problems switching between Wi-Fi and mobile internet. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile network and Bluetooth.This action will remove stored Wi-Fi passwords, but often solves problems with sticking in the communication module, which can block other processes.
- 📡 Switch over. DNS Wi-Fi settings on 1.1.1.1 or 8.8.8.8 to speed up server response.
- 🌐 Turn off the Wi-Fi Assistant feature if it constantly scans networks in the background.
- 📶 In the "Flight" mode, you can reset the radio module for 10 seconds if there is no network.
If you use VPN-services, remember that they encrypt traffic, which requires additional computing power. 8T included VPN can significantly reduce the overall responsiveness of the system with an active Internet connection.
☑️ Checking network settings
Radical measures: Resetting and reflashing
If software optimization didn’t work, the last argument is a factory reset, which will remove all data, apps, and settings, putting your phone back in the box. Make sure to back up your important data to the Mi Cloud cloud or your computer before doing so.
You can reset via Settings menu → About phone → Settings reset → Erase all data. A deeper method is through Recovery mode (pressing the volume button up and power when the phone is off). After reset, take your time to install all the applications at once. Let the system work in its pure form for about an hour to index files and adjust the background processes.
⚠️ Warning: After the reset, the system will warm up for several hours and load the data, during which time increased battery consumption and heating are possible - this is a normal process of optimizing the database.
For power users, custom firmware (like LineageOS or Pixel Experience) can be installed, which completely changes the software shell to pure Android, depriving them of heavy MIUI. On the Redmi Note 8T (codename willow), this gives a noticeable increase in performance, but requires unlocking the bootloader, which formally deprives of warranties and carries risks.
💡
Clean Install after a reset is always faster than updating on top of old data (Dirty Flash).
In conclusion, the Redmi Note 8T is still a decent device for everyday tasks. Proper operation, regular cleaning and the absence of “heavy” background processes will allow it to serve faithfully for a long time.
