Removing cache on Xiaomi Redmi: safe or not?

The cache in Xiaomi Redmi smartphones is temporary files that are created by apps and the system to speed up the device, but over time, they accumulate, taking up precious space and sometimes even slowing down the phone. Many users wonder: what happens if you delete the cache completely? Will it damage the system, will it disappear important data?

In this article, we’ll look at how cache cleaning affects Redmi’s work, what types of cache exist, and when it’s really worth removing it. You’ll also find step-by-step instructions for different versions of MIUI and learn how to avoid typical cleaning errors.

What is Cash and Why is It Needed?

Cache is a buffer memory that stores temporary data for quick access, and Xiaomi smartphones have three main types:

• 📱 System cache – files created by the operating system MIUI to speed up interface loading and command processing.
• 📦 Application cache – temporary data that saves programs (for example, downloaded pictures in messengers or cached pages in the browser).
• 🔄 Dalvik cache – optimized files to speed up the launch of applications (especially relevant for older versions of Android).

The main function of cache is to reduce the load on the processor and memory. For example, when you open Instagram, the app does not upload all the photos again, but takes them from the cache. This saves traffic and speeds up the work. However, over time, the cache grows to several gigabytes, which can lead to:

• ⚠️ Slowing down the phone (especially on models with 32/64 GB memory).
• 📉 Increased loading time of applications.
• 🔋 Faster battery discharge due to background cleaning.

Consequences of deleting the cache: pros and cons

Cache cleanup is not a panacea, nor is it a dangerous operation if done correctly. Let's see what happens to your Redmi after you delete temporary files.

✅ Positive effects

• 🚀 Increased free space – on some devices, the cache takes up to 5-10 GB.
• ⚡ Speeding up work – especially noticeable on budget models (Redmi) 9A, 10A, Note 8).
• 🔄 Error Correction – Sometimes a damaged cache causes crashes in applications.
• 📱 More stable work MIUI — The system stops "hanging" when switching between tasks.

❌ Possible challenges

Despite the obvious advantages, there is also a downside:

• ⏳ The first application launch will take longer – they will recreate the cache.
• 🔄 Loss of temporary data – for example, a history in a browser or unsaved drafts in messengers.
• 📱 Possible interface glitches - some elements MIUI can be loaded more slowly.

⚠️ Warning: Don't confuse cache cleaning with factory resetting. When you delete the cache, your photos, contacts and messages remain intact!

How to Clean Cache on Xiaomi Redmi

The cleaning process depends on the MIUI version and the phone model. We'll look at universal methods for all Redmi devices, including the Note 10 Pro, 9T, 8A and others.

📱 Method 1: Clearing the cache of a separate application

If a particular app (such as Facebook or Telegram) is slowing down, just clear the cache:

1. Open Settings → Applications → Application Management.
2. Select the app you want (such as Chrome).
3. Press Warehouse. → Clear the cache.

Close all apps in the background |Plug your phone to charge (if the battery level is below 20%)|Put a backup of important data |Check the free space on your device-->

🗑️ Method 2: Mass cleaning the cache of all applications

For complete cleaning:

1. Go to Settings. → Memory.
2. Click Clear in the "App Cache" section.
3. Confirm the action.

On some firmware, the path may differ: Settings → Additional → Cleaning.

🔧 Method 3: Cleaning Dalvik cache (for advanced ones)

This method requires superuser (root) or custom recaveri (TWRP) rights. Not recommended for beginners!

1. Turn off the phone.


2.Put Volume up + Food to enter the recaveri.




3. Select Advanced → Wipe Dalvik Cache.




4. Reset the device.

⚠️ Attention: Incorrect actions in TWRP They can cause a phone to break down. If you're not sure, don't experiment!

💡

After the cache is cleaned, restart the phone, which will help the system recover critical temporary files without errors.

What to do if after cleaning the cache, the phone began to work worse

In rare cases, users experience problems after deleting the cache, and here are the typical symptoms and solutions:

If problems persist:

1. Check the free space on the device (should be at least 1 GB).
2. Update the firmware to the latest version of MIUI.
3. Perform a reset of the launcher settings: press on the home screen → Screen settings → Reset.

When you should NOT clean the cache

Despite the obvious benefits, there are situations where cleaning the cache can harm:

• 📶 Weak Internet – applications will have to re-download data, which will take a lot of traffic.
• 🔋 Low battery power – Cache recovery consumes extra energy.
• 📱 Before an important event – for example, if you urgently need to open a document from Google Drive cache.
• 🔄 When using custom firmware - some modifications MIUI They may work unsteadily after cleaning.

It is also not recommended to clean the cache:

• 🎮 Gaming applications – this will lead to textures reloading and increase startup time.
• 📺 Streaming services (YouTube, Netflix) – cache stores data for smooth playback.

💡

Clean the cache only when you really need it — when the phone is slowing down or running out of memory — and cleaning it regularly “just in case” can only impair performance.

How to Automate Cache Cleanup

If you are lazy to manually clean the cache, you can set up automatic cleaning:

🤖 Method 1: Integrated tools MIUI

The new MIUI 12/13/14 features Auto Cleanup:

1. Open the Settings → Memory.
2. Activate the automatic cleaning option.
3. Choose the frequency (daily/weekly).

📱 Method 2: Third-party applications

Popular Utilities for Automation:

• 🧹 CCleaner – clears the cache on schedule.
• 🔍 SD Maid – deletes unnecessary files, including residual cache.
• 📊 Files by Google – has a built-in cache cleaner.

⚠️ Note: Some cache cleaners may delete important system files. Check the reviews and reputation of the app before using it!

For Redmi models with MIUI 14 and later, it is better to use built-in tools – they are optimized for firmware and do not cause conflicts.
