Owners of the once popular Xiaomi Redmi Note 8 T often face a situation where the device starts to work slower than in the first months after purchase. This is a natural process for any electronics, but in the case of budget and mid-budget models, it can manifest itself more acutely due to limited hardware resources. System optimization becomes a critical task if you plan to extend the life of the gadget.
The main problem is that modern applications and the MIUI shell itself are becoming more demanding with each passing year. The MediaTek Helio G85 processor, which did a great job in 2019, is now struggling with heavy interfaces and resource-intensive games. Understanding what causes delays is the first step to restoring comfortable speed.
In this article, we’ll look at all the possible causes, from overcrowded memory to software conflicts, and offer specific solutions. You don’t need to be an expert in Android systems to perform the steps described below. We’ll help you get your Redmi Note 8 T responsive without having to carry it to the service center right away.
Hardware limitations and memory wear
The first thing to consider is the physical characteristics of your device. The Redmi Note 8 T comes with 4 or 6 GB of RAM, which is the minimum comfortable level for modern standards. When you open many applications at once, RAM is overflowing, and the system has to constantly unload background processes, which causes noticeable delays when switching.
The second important aspect is the wear and tear of the built-in drive: the type of memory eMMC 5.1 used in this model loses write and read speed over time; the reduction in write speed on the drive can reach 40% after two years of active use, which leads to the fact that it takes longer to start applications and save files, creating a feeling of “slowdown” interface.
And you also have to consider heat generation, and when you're working a lot of work, the processor gets hot, and the trottling mechanism kicks in, and it artificially lowers the frequencies to cool you down, if you notice that the phone starts to lay down just after that. 10-15 minutes of playing or shooting video, the reason lies in thermal throttling.
⚠️ Warning: Constant overheating of the case above 45 degrees can cause the battery to bloat and the plumes inside the device to detach.Do not use the phone while charging at high loads.
Unfortunately, it is impossible to replace RAM or processor, but you can minimize the load on them. Regularly restarting the device helps to clear the cache of the system and free up resources that have been blocked by faulty processes.
Overflow of internal memory and cache
One of the most common reasons why the Xiaomi Redmi Note 8 T starts to slow down is the critical filling of the built-in storage. When the free space is less than 10-15% of the total, the Android file system starts to work inefficiently.
Special attention should be paid to messengers like Telegram and WhatsApp, which tend to accumulate gigabytes of cache that is not deleted automatically. clogged app cache is "junk" that slows down the search for the desired data. Clearing the cache through settings or built-in "Security" application can give instant performance gains.
Below is a table showing the effect of memory occupancy on the system speed:
| Memory occupancy | Impact on speed | Recommended action |
|---|---|---|
| 0-70% | Work is stable, without delay | Planned cleaning once a month |
| 70-85% | Rare twitching is possible | Delete unnecessary files |
| 85-95% | Notable lags, long launch of apps | Urgent cleaning of cache and photos |
| 95-100% | Critical freezes, software errors | Immediate discharge or cleaning |
To clean up effectively, use the built-in storage analyzer. Go to Settings → Memory and see which categories occupy the most space. Often, it turns out that half of the volume is occupied by long-forgotten videos or duplicate photos.
💡
Use the Cleanup function in the Security app, but be careful: do not delete the cache of important applications (for example, banking) if you do not want to re-enter passwords and settings.
Effects of MIUI shell and background processes
Xiaomi’s MIUI shell is famous for its functionality, but it’s also known for its resource gluttony. A host of built-in services, ad modules, and analytics work in the background, consuming the processing power of the processor. On the Redmi Note 8 T, this is especially noticeable, as the margin of performance is not unlimited.
System process msa (MIUI System Ads and other services can load your phone even when you're at rest. Turning off ads and limiting background activity is an important step to speed up, not only adding smoothness, but also saving battery life.
- 🚀 Go to Settings. → Passwords and security → Access to personal data and disable access to system services you do not use.
- 🚀 In the Settings section → Advanced settings → Access to data limit background activity for rarely used applications.
- 🚀 Turn off autoplay video in the news feed Mi Browser and the application "Music".
It's also worth checking the boot list. Many apps prescribe themselves to start, running with the phone and staying on the memory. Take everything out of there except messengers and alarm clocks.
⚠️ Note: Do not disable system processes that you do not know the names of (for example, related to the system). MIUI, This can cause your phone to malfunction or loss of notifications (push.
Problems with software and updates
Often users wonder whether to upgrade to the latest version of Android or MIUI. For the Redmi Note 8 T, which is no longer the flagship, new versions of the software can be too heavy. An update optimized for more powerful processors on your device can cause software conflicts and performance decline.
If the phone started to brake immediately after the update, it may be that the system is indexing files or that there is an error when installing, in which case it is recommended to wait a couple of days or reset the settings. However, if you are on a stable version and there are no critical security updates, sometimes it is better to stay on the current build.
Should I roll back the software version?
Check for system updates by going to Settings → About Phone → MIUI version. If a major update is available, be sure to back up your data before installing it. Also keep an eye out for versions of key apps like Google Play Services, as their incorrect performance often causes lags throughout the system.
Animation and Visual Effects Settings
Visual smoothness of the interface is not just a matter of power, but also of display settings. Xiaomi Redmi Note 8 T has a 60Hz refresh rate screen, but heavy MIUI animations can create the illusion of slow work.
To access these settings, activate the developer mode. Click 7 times in a row on the MIUI version in the About Phone menu. After that, in the Additional → For developers, find the paragraphs "Scale of Windows Animation", "Scale of Transition Animation" and "Scale of Animator Duration".
- 🎨 Set the value 0.5x This will speed up the opening and closing of windows visually.
- 🎨 Disable the function "Advanced memory" (if available in your version of the software), as using part of the internal memory for RAM on slow eMMC drives often gives the opposite effect.
- 🎨 Remove the live wallpaper and heavy widgets from the main screen, they are constantly expending resources. GPU.
☑️ Checklist of visual optimization
These changes will not add power to the processor, but will significantly reduce the time waiting for frames to be rendered, and the user will immediately notice that the phone has become more responsive to touch.
Cardinal measures: Resetting and flashing
If the software methods don't work, the radical but effective way is to completely reset to factory settings, which will remove all the accumulated "junk", erroneous configurations and application conflicts, before you save important data to the cloud or to the computer.
The reset procedure is done through the Settings menu → About Phone → Reset → Erase all data. After that, the phone will look like new. It is recommended in the early days not to install dozens of applications at once, but to watch the operation of the “clean” system.
For advanced users, custom firmware (like LineageOS or Pixel Experience) can be installed. Pure Android runs on the Redmi Note 8 T much easier and faster than heavy MIUI. However, this requires unlocking the bootloader, which formally deprives of warranties (although for this model it is likely already expired) and carries risks.
⚠️ Warning: When flashing or resetting all data will be destroyed. Make sure the battery is above 60% and the device is connected to stable Wi-Fi so that the process does not interrupt.
💡
Factory Reset eliminates 90% of the software causes of brakes, returning the speed of the first days of use.
