Cache Clearing on Xiaomi Redmi Note 7: A Complete Guide with Pictures and Warnings

Your Xiaomi Redmi Note 7 is slowing down, apps are loading for a long time, and free space on the disk is melting before your eyes? Most likely, cache is clogged - temporary files that the system and programs create to speed up work. Over time, they accumulate, taking up gigabytes of memory and slowing down the smartphone. In this article, you will find 5 proven ways to clean the cache - from basic to advanced, with explanations of when and what method to use.

We're not going to be limited to standard tips like "get into settings," but here you'll learn how to clear the cache of individual applications without deleting their data, why you shouldn't manually clean the cache of com.android.systemui, and what to do if the phone starts to overheat after cleaning, and a table of performance and risk comparisons so you can choose the best option for your situation.

Why Redmi Note 7 cache should be cleaned regularly

Cache is not garbage, it's buffer files that speed up the system and the applications. For example, when you open Instagram, the app stores thumbnails of photos in the cache so that the next run shows them instantly. The problem is that many programs don't know how to clean themselves.

• 📱 He's studying till 5-10 GB of memory – especially if you actively use social networks, instant messengers and games.
• 🐢 Brakes the interface: animations twitch, applications open for a long time.
• 🔥 Overheating processor – the system spends resources on processing unnecessary files.
• 🔄 Failures: Some programs may produce errors due to a damaged cache.

On the Redmi Note 7 with its Snapdragon 660 and 3/4 GB of RAM, cache cache is particularly acute. But the caveat is that not all cache can be deleted without consequences. For example, cleaning the cache of system applications like com.miui.home will lead to a reset of wallpaper and widgets, and deleting the cache of com.android.phone can disrupt the mobile network.

Method 1: Clearing the cache of individual applications through settings

The safest method is to remove the cache only of programs that actually slow down or take up too much space. On the Redmi Note 7 with MIUI 10-14, the path to the cleaning menu may be slightly different, but the overall scheme is the same:

1. Open Settings → Applications → Application Management.
2. Slip on the three dots in the upper right corner and select Sort by size.
3. In the list, find applications with a large amount of cache (usually YouTube, Facebook, Telegram, games).
4. Click on the app → Storage → Clear the cache.

Important observations:

• 🚫 Do not clear the cache of system applications (starting with com.android. or com.miui.) unless you know what they are responsible for.
• 🔄 After clearing the Google Play Store cache (com.android.vending) may need a reboot.
• 📊 V MIUI 12+ Deep Clean Up is a feature that removes not only the cache, but also unnecessary application files.

Remember the login and password from the account in the application (if authorization is required)

Close the application through the multitasking menu

Check if the application is used for background tasks (for example, downloading files)

Connect your phone to charge if the battery level is below 30%-->

If the app is slower after cleaning the cache, it takes time to recover the buffer files, and usually the performance is restored after 1-2 runs.

Method 2: Completely clean the cache of all applications (without root)

If you need to make room quickly and don’t want to mess with each application separately, use the built-in MIUI function:

1. Go to Settings. → Memory.
2. Click on Cleanup (in some versions – Optimization).
3. Select the Cash applications and confirm the cleanup.

This method removes the cache of all user applications, but does not touch the system files.

• ⚡ Fast, it takes less than a minute.
• 🛡️ Safe – does not affect personal data.
• 📉 Frees you from 500 MB to 3-4 GB (depends on the number of programs installed).

Cons:

• 🔄 The next time you run the app will load longer.
• 🎮 Games can “suppress” until they recover the cache textures.
• 📱 Some widgets (such as weather) will reset to standard.

💡

After the cache is completely cleaned, restart the phone, which will help the system to properly reassemble temporary files and avoid minor interface glitches.

Method 3: Cleaning the cache with Recovery Mode (for experienced)

If the phone is slow and does not respond to standard methods, you can use the recovery mode. This method deletes all temporary files of the system, including the update cache and Dalvik cache (optimized files for fast download of applications).

Instructions:

1. Turn off the Redmi Note 7.
2. Press the Power button + Volume up at the same time and hold for 10-15 seconds until the Mi logo appears.

4. Confirm the action and wait until the completion (usually 1-2 minutes).
5. Reboot your phone with Reboot → Reboot to System.

What's important to know:

• 🔧 This method resets the cache of all applications and systems, including Dalvik optimization.
• ⚠️ The first launch after cleaning will take 5-10 minutes - the system will reassemble the cache.
• 📵 If the phone doesn't turn on after the procedure for more than 15 minutes, you accidentally chose Wipe All Data, which means you will need to restore it through your Mi Account.

Method 4: Using ADB for deep cleaning (for advanced)

If you are familiar with ADB (Android Debug Bridge), you can clear your cache more selectively, including system files that are not available through the standard menu.

• 📱 Phone infected with adver viruses that hide in cache.
• 🔧 You need to delete the cache of a particular system application (e.g. com.miui.securitycenter).
• 🛠️ Standard methods don't help, and Recovery is not available.

Step-by-step:

1. Install. ADB-computer-driver.
2. Turn on the phone Developer Mode (7 taps on the MIUI version in Settings → About phone) and activate Debugging over USB.

adb devices

(device to appear)

adb shell pm list packages -f | grep cache

(Shows apps with large cache)

adb shell pm clear --user 0 com.example.app

(Replace com.example.app with the desired application package)

Warnings:

⚠️ Note: Do not clear the cache of com.qualcomm packets. - These are system files of the Snapdragon 660 processor. their deletion may lead to unstable operation of the communication module or camera.

⚠️ Warning: Adb shell pm clear command deletes all application data, not just cache! To clear only cache, use:

adb shell pm clear --user 0 com.example.app --cache-only

Method 5: Automatically clean the cache with a scheduler

MIUI has a built-in tool for automatic cache cleaning on schedule, which is handy if you don't want to think about manual cleaning.

1. Go to Settings → Memory → Cleanup.
2. Put it on the gear icon (⚙️) top-right.
3. Turn on the Auto Clean option and select the frequency (daily, weekly or with memory shortages).
4. Activate Deep Cleanup if you want to delete unnecessary APKs and temporary files.

Pros of the method:

• ⏰ It works in the background – does not require your participation.
• 📊 You can set the free memory threshold (for example, clear the cache when less than 1 GB remains).

Cons:

• 🔄 Can clean the cache too aggressively, which often used applications will slow down.
• 📵 Some system files (such as Google Services cache) are not automatically cleared.

💡

Autocleaning the cache in MIUI does not delete files of system applications related to security (for example, com.miui.guardprovider). ADB.

• 📱 Using Play Market cleaners: Software like Clean Master or CCleaner often deletes not only cache, but also useful files, and also displays false warnings about "critical errors." Solution: use only built-in tools MIUI.
• 🔧 Cleaning the cache with Engineering Mode: This can cause the communication module or camera to crash.Solution: Never touch the settings in ##4636## unless you know what they mean.

If your phone gets worse after cleaning the cache (such as getting warm or discharged quickly), you may have deleted critical files.

1. Phone reboot.
2. Cleaning the cache through Recovery (method 3).
3. In extreme cases, reset to factory settings (but it will delete all data!).
