Why Xiaomi Redmi 5A is slowing down and how to fix it
Even the budget Xiaomi Redmi 5A (codenamed Riva) with 2GB of RAM and 16/32GB of internal storage could work quickly - but over time users face freezes, slow download of applications and the message "Not enough memory." The reason is not always a small amount of storage: more often to blame system debris, fragmented files and background processes that MIUI does not optimize automatically.
In this article, 7 ways to clean memory, from simple (cache removal) to radical (factory reset) all methods tested on Redmi 5A with MIUI 12-14 and relevant for 2026. Important: before any manipulation check the real state of memory in Settings β Phone β Memory. If it shows that 16 GB is free less than 1 GB, start cleaning immediately.
β οΈ Attention: On Redmi 5A With 16GB of memory, you can't install heavy games like Genshin Impact or Call of Duty Mobile -- the system just can't do it. Cleanup will help speed up work, but it won't turn a budget player into a flagship.
1.Cleaning App Cache: A Quick Way to Free 1β3 GB
Cache is a temporary file that applications create to speed up work. Over time, it takes up gigabytes, although it can be safely deleted. On Redmi 5A, the cache is cleaned in two ways: for individual applications or completely.
How to clear the cache for a specific application:
- Go to Settings β Applications β Application Management.
- Select an app (such as YouTube or Facebook).
- Click Clear Cache (not to be confused with Clear Data β it will delete logins!).
How to clean the entire cache at once:
- π± Open the Settings. β Memory. β Clear the cache.
- π Confirm the action β the system will delete unnecessary files in a few seconds.
- β οΈ After cleaning, the first launches of applications can be slower (cache will be created again).
π‘
If the app gets worse after cleaning the cache (for example, Google Maps loads cards for a long time), try restarting the phone.
2. manually removing unnecessary files: where to look for garbage
MIUI It hides many folders of garbage, but you can find them through the built-in file manager or third-party applications like Files by Google. 5A:
| Type of file | Where to find | How much does it take? | Can I remove it? |
|---|---|---|---|
| Screenshots | /storage/emulated/0/Pictures/Screenshots | 500MB - 2GB | Yes. |
| Downloads (APK, PDF, ZIP) | /storage/emulated/0/Download | 1-5 GB | Yes (except for important documents) |
| MIUI Logs and Dumps | /storage/emulated/0/MIUI/debug_log | 100-300 MB | Yeah (unless you debug your phone) |
| Residual application files | /storage/emulated/0/Android/data | up to 1GB | Remote application folders only |
How to safely remove:
- Open Files (standard MIUI application).
- Go to the Categories section β Large Files or Garbage.
- Mark unnecessary files and click βDeleteβ.
Outdated. APK-files from the Download folder
Screenshots over 3 months old
Logs. MIUI file debug_log
Cache of remote applications in /Android/data-->
β οΈ Note: Do not delete files in folders /system or /vendor β This will cause the system to collapse and require reflashing.
3. MIUI Optimization: Disabling Autoboot and Background Processes
Xiaomi Redmi 5A on MIUI is wrong because many apps run automatically and hang in the background, consuming memory. For example, Mi Video, Mi Music or Cleaner can work even if you don't use them. You can turn off autoboot without root rights.
How to turn off autoboot:
- Go to Settings β Applications β Application Management.
- Select an app (such as Facebook).
- Press Auto Start and turn off the slider.
- Do the same for "Background Activity" (if there is such a item).
List of applications that can be safely disabled:
- π΅ Mi Music (if you use Spotify or YouTube Music)
- π¬ Mi Video (replace by Mi Video) VLC or MX Player)
- π§Ή Cleaner (built-in cleaning utility often works idlely)
- π° Mi Browser (if you use Chrome or Firefox)
- π Security (antivirus) MIUI, It is not useful if you have Google Play Protect)

β οΈ Warning: Do not disable autoboot for Google Play Services, Miui System or Telephony β this will disrupt your phone (no more will come) SMS notice).
4. Data transfer to SD-Map: How to properly expand memory
Redmi 5A supports microSD up to 256 GB, but MIUI does not always allow you to transfer applications to a memory card. However, photos, videos and documents can be moved without problems. Important: use a class 10 card (UHS-I), otherwise read / write speed will slow down the system.
How to transfer files to SD-map:
- Insert the memory card (if not already inserted).
- Open the files. β Internal memory.
- Select folders (such as DCIM or Download).
- Click "Transfer" and select SD-map.
How do you do it? SD-The internal memory card (Adoptable Storage):
- β οΈ This method formats the card and makes it tethered to the phone (will not read on PC!).
- π± Go to Settings. β Memory. β Memory map.
- π Press "SettingsΒ» β Β«Formatting as an internalΒ».
- π After formatting, transfer the data through Settings β Memory. β Data portability.
What happens if you take it out? SD-map after formatting as an internal?
5.Reset to factory settings: Last chance for 'junk' phone
If previous methods didn't work, and the Redmi 5A still slows down, it's a hard reset, which will delete all the data, including photos, messages and apps, but return the phone to its original speed.
- π€ Make a backup copy through Settings β Additionally. β Backup.
- π Remember the username and password from the Mi Account (required after resetting).
- π± Charge your phone at least 50% (reset takes 5-10 minutes).
How to reset:
- Go to Settings β About the phone β Reset settings.
- Select βErase all dataβ.
- Enter a pattern lock or PIN-code.
- Confirm the action and wait for the reboot.
Once reset, the phone will turn on as new. Don't restore all the data at once -- check the speed first, then selectively transfer only the files you need.

Resetting to factory settings is the only way to remove MIUI system debris that accumulates over the years and is not cleaned by standard methods.
6. Alternative methods: for advanced users
If youβre willing to go beyond standard settings, these methods will help you make the most of the Redmi 5A:
(a) Disabling animations (interface speed)
MIUI uses animations that slow down the work on weak devices to turn them off:
- Activate Developer Mode (7 times click on Version) MIUIΒ» In Settings β The phone).
- Go to Settings β Additional β For developers.
- Find the items: Window animation scale β Turn off animation scale transition β Turn off animation duration β 0.5x
(b) Installation of lightweight firmware
The official MIUI firmware for Redmi 5A is often overloaded with unnecessary features, with custom firmware like:
- π LineageOS (Pure Android without a free Android) MIUI)
- β‘ Pixel Experience (like the Google Pixel interface)
- π MIUI Lite (Lightweight version of the standard shell)
β οΈ Attention: Installation of custom firmware requires unlocking the bootloader and may result in loss of warranty.
(c) Use of ADB for deep cleaning
With Android Debug Bridge (ADB), you can uninstall system applications that are not normally deleted, such as the command to delete Mi Video:
adb shell pm uninstall --user 0 com.miui.videoplayerπ List of safe packet removal:
- com.miui.analytics (MIUI statistics collection)
- com.miui.cleanmaster (built-in cleaning)
- com.miui.miservice (advertising services)
7.How to prevent future memory clogging
To prevent the Redmi 5A from brake again in a month, follow these rules:
- π΅ Remove the cache once every 2 weeks (via Settings) β Memory).
- π« Do not install βoptimizersβ from the Play Market (such as Clean Master or the Game). DU Speed Booster β They only make the problem worse.
- π₯ Use Lite versions of apps (e.g. Facebook Lite, Messenger Lite).
- π Regularly transfer photos and videos to your PC or cloud (Google Photos with High Quality compression does not take place).
- π Turn off background sync for unnecessary accounts (e.g. Mi Cloud if you are not using it).
If you install/remove apps frequently, turn on autocleaning:
- Go to Settings β Memory β Autoclean.
- Turn on the option and set a schedule (e.g. every Saturday at 3:00 a.m.).

On the Redmi 5A with 16 GB of memory, leave at least 1.5-2 GB free. This will prevent lags and allow the system to work normally.
