Why Xiaomi Cache Should Be Cleaned Regularly
Cache is a temporary file that creates apps and a system to speed up work. On Xiaomi, Redmi and POCO smartphones, the cache can take up gigabytes of memory even if you donโt actively install new programs. For example, social networks like Facebook or TikTok accumulate up to 500 MB of cache per month of active use, and MIUI system processes accumulate even more.
If you do not clean the cache in time, you will encounter:
- ๐ข Slowing down the phone (lags when opening applications, hanging animations)
- ๐ Lack of memory (notification "Memory is filled" when 10-15 GB of free space)
- ๐ Spontaneous reboots (especially on models with 3-4 GB RAM)
- ๐ฑ Overheating of the device (cache makes the processor work harder)
Unlike factory resets, cache cleaning does not delete personal data (photos, contacts, messages) and is a safe procedure, but it must be done correctly โ not all files in /cache can be manually deleted.
How to clean the cache through the settings Xiaomi
Xiaomi smartphones have three official ways to clean the cache without third-party programs, all of which are available through the standard Settings menu, but differ in depth of cleaning and consequences for the system.
1. Clearing the cache of individual applications
The most targeted method is to remove cache for specific programs, which is useful if you slow down only one application (for example, Instagram or Google Chrome).
Instructions:
- Open Settings โ Applications โ Application Management.
- Select the appropriate app (e.g. YouTube).
- Press Warehouse. โ Clear the cache.
- Confirm the action (some models will require a password).
Close the application through the "Last" menu
Make sure you have enough battery power (minimum 20%)
Save important data from the application (for example, drafts in messengers)
Turn off the auto-update app in Google Play while cleaned
-->
โ ๏ธ Note: Do not clear the cache for system applications like com.android.systemui or com.miui.home โ this can cause shell malfunctions. MIUI. If you are not sure what the app does, it is best to skip it.
2. Mass cleaning of cache of all applications
If the phone is slowing down a lot and manually cleaning each app takes a long time, use the built-in Cleanup feature in MIUI. It removes the cache of all user programs at a time.
How to do this:
- Go to Settings. โ Memory.
- Click Clean in the section "Junk files".

| Redmi 9A/9C | Settings โ Additional โ Cleaning | The function is hidden in the submenu |
๐ก Useful tip: After a mass cleaning, restart your phone to help the system reassemble the cache of critical processes and avoid lag in the first hours of operation.
3. Cleaning the system cache (for power users)
This method removes temporary MIUI files, including update cache, bug data, and logs, and is useful if the phone starts spontaneously restarting after a firmware update or artifacts appear in the interface.
How to do this:
- Open the Settings. โ The phone.
- Click 7 times on the MIUI version to activate the developer mode.

โ ๏ธ Note: Do not use this method more often 1 time-in 2-3 Excessive cleaning of the system cache can lead to slowdown of the work MIUI, The system will have to reassemble temporary files from scratch every time.
What happens if you clear the cache: consequences and myths
Many users are afraid to clean the cache for fear of losing data or breaking their phone, and we'll take a look at the real consequences and debunk popular myths.
The Real Effects of Cache Cleaning
- โ Speed up work โ applications will start faster first 1-2 The day (until the cache is re-accumulated).
- โ Freeing of memory โ on average, freed 1-3 GB (depends on the number of installed applications).
- โ ๏ธ Temporary inconveniences: Applications will take time to re-upload data (for example, Google Maps will re-download maps). Some settings in games will reset (for example, graphic presets in the game). PUBG Websites in the browser will be loaded longer (cache of images and scripts removed).
- โ What NOT will happen: No accounts, messages, or media files will be deleted, Wi-Fi or Bluetooth settings will not reset, firmware will not fly or bootloader will not be blocked.
Common myths about cache
Myth 1: โThe more cache, the faster the phone worksโ
Reality: Cash only speeds up when itโs up to date; outdated temporary files (like Instagramโs six-month cache) only take up space and slow down the search for the data.
Myth 2: โCache cleaning is bad for the batteryโ
Reality: The cleaning procedure itself doesnโt affect the battery, but after that, some applications can consume more power in the first hours (due to re-loading data).
Myth 3: โCache can only be cleaned through Recoveryโ
Reality: Cleaning through Recovery (the wipe cache partition command) only removes the system cache, but does not affect the application cache.

Now you can clear the cache in one tap without going into the settings.
What to do if the cache is not cleared
Sometimes users find that the Clear cache button is inactive or that the space is not vacated after cleaning, and we'll look at the main reasons and solutions.
1. The "Clear Cache" button is not pressed.
This happens in three cases:
- ๐ The app is system-based (e.g. com.android.phone) Solution: Don't touch it unless you're sure of the consequences.
- ๐ก๏ธ Change protection is enabled (on some firmware). Solution: disable it in Settings โ Special facilities โ Protection from change.
- ๐ฑ The app is currently running. Solution: Close it through the Last Menu or restart your phone.
2. after cleaning the place is not vacated
If you cleared the cache but the free space has not increased, check:

- ๐ธ folder DCIM/.thumbnails โ Here are the photos that can weigh up to 1 GB.
- ๐ฆ Temporary update files (/cache or /data/ota_package).

If you are trying to clear the system cache through Recovery, but the wipe cache partition command does not work:
- Make sure you have official Recovery (the path may be different on custom firmware).
- Check if the boot loader is locked (fastboot oem device-info in ADB).
- On some models (Redmi Note 8 Pro, POCO X2), the system cache is cleared only through Fastboot: fastboot erase cache.
โ ๏ธ Warning: If after cleaning the system cache, the phone is stuck on the logo MI, Don't panic. 10-15 If you're stuck for more than an hour, you'll have to reflash the device through the Mi Flash Tool.
Additional tips on memory optimization on Xiaomi
