Cache Clearing on Xiaomi Redmi Note 6 Pro: The Complete Guide

The Xiaomi Redmi Note 6 Pro is a popular smartphone with powerful hardware, but even it eventually starts to “brake” because of the filled cache of applications and systems. Unlike the new models with MIUI 14+, this model (released in 2018) requires a special approach: standard cleaning methods may not work due to the outdated version of MIUI 9/10.

In this article, 5 proven ways to clean up cache, including hidden features of Redmi Note 6 Pro that are not described in the official documentation, we will discuss how to remove cache for individual applications, system cache through Recovery, and even how to automate the process with ADB. Importantly, in this model, cleaning the cache through Settings → Storage only removes part of the temporary files – the system cache remains intact.

Why Redmi Note 6 Pro cache should be cleaned regularly

Cache is a temporary file that creates applications and a system to speed up work. On the Redmi Note 6 Pro (with a Snapdragon 636 and 3/4 GB of RAM), cache takes a critical place:

• 📱 Apps (Facebook, Instagram, instant messengers) accumulate up to 1-3 GB of cache per month.
• 🔄 Dalvik-cache takes up to 500 MB and is not cleaned by standard means.
• 🐢 Slowdown: when filling memory by 80%+ The smartphone is starting to “hang up».
• 🔋 Battery discharge: background cache overwriting increases consumption by 10-15%.

The Redmi Note 6 Pro is not featured in MIUI 9/10, which automatically cleans the cache in new versions, so users have to do it manually, but there is a caveat: clearing the cache through the settings does not affect the system files, which occupy the lion's share of memory.

Method 1: Clearing the cache of individual applications through settings

The safest method is to remove cache for specific programs, which is suitable if you slow down one or two applications (for example, WhatsApp or Google Chrome).

1. Open Settings → Applications → Application Management.
2. Select the appropriate app (such as Facebook).
3. Press Warehouse. → Clear the cache.
4. For complete cleanup (including login data), use Clear Data only if you are ready to reconfigure the application!

⚠️ Warning: Do not clear the cache for system applications (com.android.phone, com.miui.home) – this can cause malfunctions in the phone.

Make a backup copy of important data (photos, contacts)

Close all background applications

Connect your phone to charge (if charge < 30%)

Check the space in the memory (should be > 500MB)-->

Method 2: Clean the entire cache with Recovery Mode

If your smartphone is slowing down and standard methods don’t work, use Recovery Mode, which removes all cache, including system cache, but does not affect user data (photos, messages).

1. Turn off the phone.
2. Press the Power Button + Volume up for 5-10 seconds at the same time until the Mi logo appears.
3. In the Recovery menu, select Wipe & Reset → Wipe Cache (control – volume buttons, confirmation – power button).
4. After cleaning, restart your phone (Reboot → Reboot to System).

The process will take 2-5 minutes. After the restart, the smartphone will work faster, but the first 10-15 minutes can warm up - this is normal (the system restores temporary files).

⚠️ Note: Some Redmi Note 6 Pro firmware (especially custom ones) may not have Wipe Cache. → Cache.

Method 3: Automatically clean the cache with ADB

For power users, ADB (Android Debug Bridge) allows you to clear the cache without manual intervention, a method that is useful if you need to clean the cache regularly (for example, for testing applications).

What you need:

• 💻 Computer installed ADB Tools.
• 🔌 USB-cable (preferably original).
• ⚙️ Included Debugging by USB on the phone (Settings) → The phone. → Version. MIUI — Press 7 times, then return to Settings → Additionally. → For developers).

Instructions:

1. Connect your phone to your PC and open Command Prompt (Windows) or Terminal (Mac/Linux).
2. Enter the command to check the connection: Adb devices must appear serial number of your device.
3. Clear the cache of all applications: adb shell pm trim-caches -1
4. To clean the system cache (Dalvik-cache): adb shell rm -r /data/dalvik-cache/*

Once you have completed the commands, restart your phone.This method does not delete user data, but it requires caution - incorrect ADB commands can damage the system.

1. Reinstall Xiaomi USB Drivers drivers.

2. Use another USB-cable (not all support data transmission).

3. Enable the option Cancel authorization in the developer settings USB-debugging and reconnecting.-->

Method 4: Use third-party apps (with caution!)

Google Play has dozens of cache-cleaning apps (e.g. CCleaner, Files by Google, SD Maid), but the Redmi Note 6 Pro has limitations:

• ✅ Pros: automate the process, show “junk” files.
• ❌ Cons: Do not clean Dalvik-cache (custom cache only); can delete files (such as the cache of cards in Google Maps); Some applications (Clean Master) accumulate cache themselves.

If you decide to use such software, follow the rules:

1. Install only one application (not several at the same time).
2. Before cleaning, check the list of files for deletion.
3. Do not give the application the rights of the administrator of the device.

💡

On the Redmi Note 6 Pro, it is best to avoid “optimizers” as they often conflict with MIUI 9/10 and can cause the processor to overheat.

Method 5: Manually clean the cache through the file manager

For those who like to control the process, manual cleaning through a file manager (such as Mi File Manager or Solid Explorer) is a good way to choose which files to delete.

How to do this:

1. Open the file manager and go to /storage/emulated/0/Android/data/.
2. Find folders with app names (e.g. com.facebook.katana for Facebook).
3. Inside each folder, remove the cache subfolder.
4. For the system cache, go to /data/dalvik-cache/ (root rights required).

The advantage of this method is selective cleaning, for example, you can delete the cache only for games, leaving the data of messengers intact, but without root rights, you can not clear the system cache.

⚠️ Attention: Delete files in folders /system or /data root-free can cause applications to crash.Always check file extensions before deleting (cache usually has.tmp,.cache,.log extensions).

Frequent Cache Clearing Errors on Redmi Note 6 Pro

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

Another common problem is that cleaning the cache doesn't work.

• 🔋 Battery's dead (< 20% – the system limits background processes.
• 📱 Too many background apps – close them through recent apps before cleaning.
• 🔄 Failure to work MIUI — Resetting or resetting settings (Settings) → Additionally. → Resetting settings).
