Xiaomi Redmi 7A was launched in 2019 and was originally marketed as an affordable device for basic tasks. However, as time passed and applications were updated, the MIUI operating system began to require more resources, which often leads to noticeable interface delays. If your phone started to slow down, it does not always mean you need to buy a new gadget.
The main reason for the performance decline is the hardware limitations of the Snapdragon 439 processor and eMMC 5.1 drive, which can not cope with modern heavy versions of messengers and social networks, and over time, the system accumulates software debris, and fragmentation of memory reduces the speed of reading data.
In this article, we will discuss proven ways to help restore the responsiveness of your device: you will learn how to properly configure hidden Android settings, clean the system cache and disable unnecessary processes that consume RAM.
Analysis of memory and storage occupancy
The first step in diagnosing slowdowns is to check for free space. Android is critically dependent on having free space on the internal drive to create temporary files and swaps.
When the space is running out, the data write speed drops dramatically, causing frizzes even when scrolling through the menu, and the critical threshold for stable work is the presence of at least 15-20% of free memory from the total volume.
Users often ignore the Download folder and messenger cache, which can take up gigabytes of space. Use the built-in Security app or third-party utilities to clean, but be careful about removing system logs.
Special attention should be paid to photos and videos, which are often duplicated in cloud services. Deleting files from the gallery does not always free up space if sync with Mi Cloud or Google Photos is enabled - check the cart.
Cleaning RAM and Process Management
The 2GB or 3GB RAM in the Redmi 7A is quickly filled with background services. The constant lack of RAM forces the system to constantly unload and reload applications, which creates a twitching effect.
To start, open the menu of running applications and press the cleaning button (usually a broomstick), but this only has a temporary effect. Deeper cleaning requires understanding which applications consume resources.
- 📱 Go to Settings. → Advanced settings → Memory to see a detailed list.
- 🚀 Forcedly stop heavy apps you’re not using right now.
- 🔋 Turn off auto-start for all programs except messengers and alarm clocks.
There is a hidden developer function that allows you to limit the number of background processes, and activation of the developer menu is done by seven times clicking on the MIUI version in the About Phone section.
💡
In the Developer menu, find the "Background Process Limit" option and set the "No More than 2 Processes" value, which drastically reduces the RAM load.
Don't just rely on built-in accelerators. They often consume resources themselves; it's better to manually control the list of tasks running and close the heavyweights before launching games or the navigation.
Optimization of visual effects and animations
The MIUI graphics interface is rich in animations that create smoothness but load the Adreno 505 GPU. On budget devices, rendering complex transitions can cause input lag.
To make the interface visually faster, you need to scale the animations, which will not speed up the processor, but will reduce the waiting time for the transitions to be completed between the screens.
In the developer menu, find three animation-related items: "Window animation," "Jump animation," and "Duration of animation." Change their value from standard 1x to 0.5x or completely disable them.
⚠️ Warning: A complete shutdown of animations could make the interface twitchy and less understandable.The optimal balance for Redmi 7A significance 0.5x.
Also worth considering is the use of minimalist themes, heavy themes with live wallpaper and complex icons put a lot of stress on the system every time you unlock the screen.
How to turn it on GPU-acceleration?
Another important aspect is the refresh rate of the screen, which is fixed in Redmi 7A, but the lower resolution in some custom launchers can give you performance gains, but you can't do this with root rights as standard tools.
Removing system debris and application cache
Over time, every application that is installed gets cached, and these are temporary files that are designed to speed up the launch, but when they overflow, they start to interfere with the system, especially browsers and social networks.
Cleaning through the standard menu often leaves deep traces. Recovery mode is a good option, but it requires caution. A safer method is to clean the data of specific applications.
Consider the table of the most bloated applications that require regular cleaning on the Redmi 7A:
| Annex | Type of data | Recommended action | Impact on speed |
|---|---|---|---|
| Google Chrome | Cash sites. | Clear the cache | High. |
| Telegram | Media files | Settings → Data and memory | Average. |
| Google Play | Temporary files | Clear the cache | Average. |
| MIUI System | Logs of updates | Through the Security App | Low. |
Regularly cleaning the cache helps avoid file version conflicts and read errors, but don’t delete the app data unless you want to reset it to factory settings.
Use the adb shell pm trim-caches 999999999 (PC connection and USB debugging required) command to force the cache of all applications to a minimum. This is an advanced method that requires ADB on the computer.
Disabling MIUI Advertising and System Services
One reason why the Xiaomi Redmi 7A might be slowing down is the background load of MSA (MIUI System Ads) ad modules, which consume Internet traffic and CPU cycles.
To turn off the ads, go to Settings → Password and Security → Access to personal data. Find the msa list and turn off the slider. The system will ask you to wait 10 seconds, then deny access.
- 🚫 Disable recommendation services in the app "Downloads".
- 🚫 In the "Security" settings, turn off receiving recommendations.
- 🚫 In the application "Music" and "Video" should also find items about displaying advertising and remove the boxes.
In addition to advertising, you should disable unnecessary system services such as Google Assistant (if not in use) or Google’s persistent desktop search, which constantly poll servers and waste resources.
☑️ Checklist for disabling ads
When you turn off the ad modules, you'll notice not only the speed increase, but also a slight increase in battery life, and the system will be cleaner and more responsive.
Resetting settings and radical methods
If software optimization fails, the last software method is a full reset to factory settings (Hard Reset), which deletes all user data and returns the system to its original state.
Before the procedure, be sure to back up important contacts and files. Reset can be done through the Settings menu → About phone → Resetting → Erase all data.
⚠️ Warning: Make sure the battery is at least 50% battery power before starting the reset. interruption of the process can damage the bootloader and not be able to turn on the phone.
An alternative and deeper method is to flash the device through the computer using the Mi Flash Tool, which allows you to install a clean version of the firmware without the system debris accumulated over the years of updates “over the air”.
For advanced users, custom firmware (such as LineageOS or Pixel Experience) can be installed, which lacks heavy MIUI shells and runs on the Redmi 7A much faster than the stock versions.
💡
Full resetting is the most effective way to programmatically speed up an old smartphone if the hardware is working.
