How to Clean Xiaomi Redmi: From Cache to Speakers

Xiaomi Redmi smartphones are known for their price-performance ratio, but even the most powerful models eventually start to slow down, most often due to clogged memory, overloaded cache or physical contamination. In this article, we will examine all the cleaning methods, from software to mechanical, that will return your Redmi to its previous speed.

It's important to understand that cleaning isn't just about removing unnecessary files, it's about optimizing your system, freeing up RAM, removing digital debris, and even physically cleaning your body from dust. We'll look at all Redmi models (from Redmi 4X to Redmi Note 13 Pro+) with MIUI firmware in mind.

If your smartphone is slow to respond to touch, apps are slow to open, and your memory is full, so don't rush to bring it to the service. In 90% of cases, you can solve the problem yourself in 10 to 30 minutes. Let's start with the simplest one: software cleaning.

1.Cache and garbage cleanup via MIUI

Xiaomi’s MIUI firmware has built-in cleaning tools, but many users don’t use them, and regular cache cleaning can free up to 3 to 5 GB of storage and speed up a smartphone by 20 to 40 percent.

Open the Security app (the shield icon) and go to Cleanup, where the system automatically scans the device for:

• 🗑️ Unnecessary files (remains of remote applications, temporary data)
• 📁 Application cache (images, scripts, data for fast download)
• 🔍 Duplicate files (repeated photos, documents)
• 📥 Downloads (old) APK, archives, unused files)

Once scanned, you'll see a list of categories with the amount of time you're taking. Don't delete the messenger cache (like WhatsApp or Telegram) because it will cause you to re-upload your media files. Better manually clear the cache for underutilized applications.

For deep cleaning, go to Settings → Applications → Application Management, select the right one and click Clear Cache. Don’t use the “Clear Data” option – this will reset the application settings to factory.

2.Relieving Memory: What Can Be Deleted Without Risk

Even if you regularly clean the cache, memory on Xiaomi Redmi can run out due to the accumulated unnecessary files.

Do not delete folders with names MIUI, Android or system, this can cause a firmware failure, and avoid cleaning the DCIM/Camera folder if you have not backed up your photo.

💡

Use Google Photos or Mi Cloud to automatically upload photos. Set up deletion of local copies after you have redundant, which will free up up to 5-10 GB of space.

To analyze the occupied space, use the Memory Analysis app in Settings → Memory. It will show which applications occupy the most space and suggest optimizing storage.

3. Optimization of applications

Many Xiaomi Redmi users experience apps running spontaneously in the background, consuming battery power and RAM. This is a feature of MIUI that can be fixed:

Go to Settings → Applications → Application Management → Autorun. Here you will see a list of programs that are allowed to run automatically. Turn off autorun for underutilized applications, especially for:

• 🎮 Games (they are often updated in the background)
• 🛒 Store apps (e.g. AliExpress, Wildberries)
• 📰 News aggregators (Yandex.Zen, Google News)
• 📊 Social networks (except for the main messengers)

Also limit background activity in Settings → Battery and Performance → Battery Management. Select Power Saving mode for unnecessary applications – this will extend battery life by 10-15%.

If some apps aren’t being updated through Google Play, check for cache in Settings → Apps → Google Play Store → Memory → Clear cache. After that, restart your phone and try updating the apps again.

4.Speakers and connectors cleaning: physical cleaning

Over time, dust accumulates in the speakers, charging connector and under the mesh of the Xiaomi Redmi microphone, which worsens the sound and communication quality.

To clean the USB-C connector:

1. Blow the connector with compressed air.
2. If you see debris, carefully remove it with a toothpick.
3. Wash the contacts with an alcohol napkin (do not leave the villi!).

⚠️ Attention! Do not use wet wipes to clean the connector - fluid can corrosion the contacts. If the phone does not charge after cleaning, check the connector for damage.

5. Reset to factory settings: when necessary

If all previous methods have failed and Xiaomi Redmi is still slow, the last chance is a hard reset, which will remove all data from the phone, so make sure to back up:

• 📱 Contacts (export to Google Account)
• 📷 Photos and videos (copy to PC or cloud)
• 🔑 Passwords (use Google Smart Lock or Keeper)
