How to Clean Up Xiaomi Phone Cache: All the Techniques of 2026

Why should Xiaomi’s cache be cleaned regularly?

Cache memory on Xiaomi smartphones (including Redmi, POCO and Black Shark models) are temporary files that create applications for fast work. Over time, they accumulate and take up up to 5-10 GB of internal memory, slowing down the system. But not everyone knows that improperly cleaning the cache can lead to app malfunctions or even data loss.

In this article, we will discuss unique methods of cleaning the cache for MIUI 14/15, which are not found in standard instructions, you will learn how to delete unnecessary files without harming performance, which applications can be cleaned without consequences, and which are better not to touch.

1. Standard cache cleaning through MIUI settings

The safest way is to use the built-in MIUI tools. This method is suitable for all Xiaomi models, including the Redmi Note 12, POCO X5 and Black Shark 5.

  1. Open the Settings β†’ Memory
  2. Click on Clean in the section "Junk files"
  3. Select the App Cash and confirm the removal

The system will automatically scan the device and show how much space can be freed up, typically 1-3 GB on a regularly used smartphone, but the caveat is that this method does not clear the cache of system applications, which often take up the most space.

Close all working applications

Connect your phone to charge (if charge < 20%)

Backup of important data

Disconnecting the mobile Internet (to speed up the process)-->

2. Deep cache cleaning for individual applications

If you want to free up as much space as possible, you'll have to manually clean the cache of each app, especially for Telegram, YouTube and TikTok, which can accumulate up to 500MB of cache each.

  1. Go to Settings β†’ Applications β†’ Application Management
  2. Select an app (such as Google Chrome)
  3. Click Warehouse β†’ Clear the cache

⚠️ Note: Do not clear the cache for MIUI System Launcher and Google Play Services – This Could Lead to Screen Failures.

AnnexAverage cache sizeCan I clean without consequences?
Telegram300-800MBYes (does not delete media files)
YouTube200-500MBYeah (the video will be uploaded longer)
Google Maps100-300MBYes (maps will be reloaded)
MIUI System Launcher50-150MBNo (interface failure risk)

Once a week.

Once a month

Only when the phone is slowing down.

3. Hidden MIUI function: Cache clearing through developer mode

Few people know, but MIUI has a hidden tool for deep cleaning, which is available through developer mode and allows you to remove cache that you can't see in standard settings.

  1. Go to Settings. β†’ The phone.
  2. Click 7 times on the MIUI version until the notification appears
  3. Back to Settings β†’ Additionally. β†’ For developers
  4. Find the item Do not store actions and turn it on

Once activated, the system will automatically clear the background cache every 4 hours, which is especially useful for devices with 4GB of RAM and less, where every megabyte counts.

What happens if you turn on "Do not store actions"?
This feature forcibly closes all background processes when the screen is locked and clears their cache. On the one hand, this frees up memory, but on the other hand, some applications (for example, messengers) will be opened longer and may not show notifications in a timely manner.

4.Cache cleanup via Recovery Mode (for power users)

If the phone is slowing down a lot and standard methods are not working, you can use the recovery menu, which deletes all temporary system files, including the update cache and Dalvik cache, but it requires caution:

  1. Turn off the phone.
  2. Press the Power button + Volume up before the Mi logo appears
  3. Select Wipe & Reset β†’ Wipe Cache (Change of Volume)
  4. Confirm the action and restart the device

⚠️ Warning: Never select Wipe Data from this menu, it will cause a complete reset of your phone, and don't interrupt the cleaning process, otherwise you risk getting a brick".

If after cleaning the cache through Recovery, the phone boots for a long time (5-10 minutes), it is normal.

5. Automatic Cache Cleanup with Security App

Every Xiaomi smartphone has a Security app that has powerful tools to optimize the system, and it can not only clean the cache, but also:

  • πŸ” Finding duplicate files
  • πŸ—‘οΈ Delete residual files after uninstallation of applications
  • πŸ“± Optimize autoloading
  • πŸ”‹ Extend battery life

To take advantage of automatic cleaning:

  1. Open the Security app
  2. Click on the Cleanup (Broom) icon
  3. Select Deep Cleanup and wait for the scan to be completed.
  4. Click Clean and confirm the action.

The advantage of this method is that the application analyzes not only the cache, but also other temporary files that standard tools do not see, for example, it finds cache from old versions of applications that have been deleted long ago.

6.Alternative methods: ADB and third-party applications

For advanced users, there are two more ways to clean the cache:

Method 1: Through ADB (without root)

If you have a computer, you can use Android Debug Bridge to clear the cache of all applications with one command:

adb shell pm trim-caches 1000000000

This command clears the cache of all applications except system ones, and the number at the end is the maximum cache size in bytes (here is 1 GB).

Method 2: Third-party applications

There are utilities on Google Play like CCleaner or Files by Google that can clean cache.

  • 🚫 Don’t give them root rights – it’s not safe.
  • πŸ” Check reviews before installation
  • πŸ“± Prefer the official tools MIUI

The cleaning side often collects data about your applications, and in most cases, built-in MIUI tools are enough.

Frequent errors in cleaning cache on Xiaomi

Many users make critical mistakes that, instead of speeding up the phone, have the opposite effect.

  1. Cleaning the cache of system applications – this can break the MIUI (for example, widgets disappear or notifications stop coming).
  2. Root-access cleaners – 90% of these applications contain malicious code or spyware.
  3. Frequent cache cleaning – if you do this daily, applications will take longer to load, as they will have to recreate temporary files.
  4. Deleting the messenger cache – in WhatsApp or Viber, this will lead to the loss of media files from chats.

⚠️ Warning: If the phone is slower after cleaning the cache, it means you have deleted critical temporary files, in which case only rebooting the device (sometimes several times in a row) will help).

Can I clear the cache without losing data?
Yes, cache cleaning doesn’t affect your photos, videos, contacts, or messages; it only deletes temporary files that apps create to speed up work; however, in some instant messengers (like Telegram), the cache includes downloaded media files, which you will have to download again.
How much space will be freed up after cleaning the cache?
It depends on how long you last cleaned your phone. On average, users free up: 1-2 GB – with regular cleaning (every 1-2 months) 3-5 GB – if not cleaned for six months or more Up to 10 GB – on devices with a lot of games (for example, Genshin Impact or Call of Duty Mobile).
Do I need to clean the cache on the new Xiaomi phone?
No, on the new device, the cache is minimal and does not affect performance. The first cleaning makes sense to do after 2-3 months of active use, when temporary files do accumulate. The exception is if you install a lot of heavy games immediately or work with graphics editors.
Why do applications load longer after cleaning the cache?
This is normal. Cache exists precisely to speed up the start of programs. Once it is cleaned, applications have to recreate temporary files, so the first run can take 20-50% longer. After 1-2 use, the speed will return to normal.
Can we turn off the caching altogether?
Technically, yes, but it's not recommended. Cache speeds up applications and reduces the workload on the processor. If you turn it off: Applications will open longer, battery consumption will increase (the processor will have to recalculate data every time) Some functions may not work correctly (for example, offline maps in Google Maps) It is better to clean the cache regularly than to refuse it completely.
