Cache Clearing on Xiaomi Redmi Note 7: A Complete Guide to Accelerating Your Smartphone

Xiaomi Redmi Note 7 remains a popular smartphone even years after its release, but over time, many users face its “brakes”. The main reason is a crowded cache that takes up precious space in memory and slows down the system. Unlike new models with 128+ GB of storage, the Note 7 often comes with 32/64 GB of memory, where every megabyte counts.

In this article, you will find three working methods for cleaning cache, from manual deletion through settings to using an engineering menu for power users, and we will also discuss which cache can be removed without risk and which should not be touched so as not to disrupt the operation of applications. All instructions are adapted for MIUI 10-14 and do not require root rights.

Why clean up the cache on Xiaomi Redmi Note 7?

Cache is a temporary file that creates applications and a system to speed up re-accessing data, for example, when you open Instagram, the app stores thumbnails of photos in the cache so that it can show them faster the next time it runs, but over time, these files accumulate and do more harm than good:

• 📉 Slowdown: Cache overflow causes the system to waste resources on processing unnecessary data.
• 📱 Lack of memory: on the Redmi Note 7 with 32 GB cache can take up to 5-10 GB.
• 🔄 Application crashes: A corrupted cache leads to program crashes (e.g. YouTube or Google Maps).
• 🔋 Increased battery consumption: the system spends energy scanning unnecessary files.

In our experience, cleaning the cache every 2-3 months increases the speed of the Redmi Note 7 by 20-30%, especially if the smartphone is actively used (social networks, games, multimedia).

⚠️ Warning: Don't confuse cache with user data! Clearing WhatsApp's cache won't delete your chats, but it will reset downloaded stickers and media previews.

Method 1: Clearing the cache of individual applications

The safest method is to remove cache for specific programs, which is useful if only one application (such as Facebook or Tinkoff-Bank) is slowed down.

1. Open Settings → Applications → Application Management.
2. Select the app you want (such as Chrome).
3. Press Warehouse.
4. Tap Clear Cache (not to be confused with Clear Data!).

For convenience, sort the applications by cache size:

1. In Application Management, click on three dots (⋮) top-right.
2. Select Sort. → By size.
3. Clear the cache from applications that are larger than 100-200 MB.

Top.-5 The apps that most often “clog” Redmi Note 7:

• 🎵 Spotify/Yandex Music (cache of songs and covers)
• 📷 Instagram/TikTok (preview of videos and stories)
• 🗺️ Google Maps/2GIS (maps and routes)
• 🎮 PUBG Mobile/Free Fire (textures and updates)
• 🌐 Chrome/Opera (webcache and cookies)

Clear the browser cache (Chrome/Opera)|Delete the cache of social networks (Instagram, VK)|Clear the cache of messengers (Telegram, WhatsApp)|Check the cache of games (if you play)|Clean the cache of cards (Google Maps, 2GIS)

⚠️ Note: After clearing the Google Play cache, the Store or Google Services may temporarily run slower – this is normal.

Method 2: Clean the system cache through Recovery

If the smartphone is slowing down or produces errors such as "UI system stopped", it will help to clean the system cache (also called Dalvik-cache), which does not delete user data, but requires a reboot to Recovery mode.

Instructions for Xiaomi Redmi Note 7:

1. Turn off the phone.
2. Press the Power + Volume buttons up at the same time and hold for 10-15 seconds until the Mi logo appears.
3. Release the buttons and you will be taken to MIUI Recovery (Mandarin/English menu).
4. Use volume buttons for navigation and power button for selection.
5. Choose Wipe & Reset → Wipe Cache.
6. Confirm action (Yes).
7. After cleaning, select Reboot → Reboot to System.

This method removes:

• 🗑️ Cache system (Dalvik-cache)
• 📦 Temporary update files
• 🔄 Logs of error

Does not delete:

• 📱 User data (photos, contacts, messages)
• 🔐 Application settings
• 📁 Files on the memory card

💡

If after cleaning the cache through Recovery, the phone boots for a long time (more than 5 minutes), do not panic - this is normal.

Method 3: Use of an engineering menu (for power users)

For advanced users, there is a method of clearing the cache through the engineering menu (#4636###), which allows you to remove the Dalvik and ART cache without rebooting it in Recovery, but you need to be careful.

Instructions:

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. In the menu that opens, select Usage statistics.
4. Press three points (⋮) In the upper right corner, select Clear Dalvik Cache.
5. Confirm the action.

Advantages of the method:

• ⚡ Faster than rebooting in Recovery.
• 🛠️ Allows you to clean the cache selectively (for example, only for the purpose of ART).
• 🔍 Detailed statistics of memory usage.

Risks:

• 🚨 Incorrect actions can lead to application failure.
• 🔧 Not all versions. MIUI support this function.

💡

The engineering menu is a powerful tool, but only use it if you're confident in what you're doing. For most users, the first two are enough.

What if cleaning the cache doesn’t help?

If the Redmi Note 7 cache is still slowing down after cleaning, the problem may be deeper.

1. Check the space: the system partition should have at least 1-1.5 GB of free space, delete unnecessary applications or transfer files to the memory card.
2. Update your firmware: go to Settings → About Phone → System Update and install the latest patches.
3. Turn off animation: Activate Developer Mode (7 times click on Version) MIUI In About Phone, then in Settings → Additionally. → For developers, set: The scale of the window animation → Off. Scale of transition animation → Duration of the animator → Off.

Reset the settings.

Also check the battery status: if the battery capacity has dropped below 70%, the phone will brake even after cleaning the cache, and you can check the battery status through the AccuBattery app or in the engineering menu (#4636## → Battery information).

⚠️ Note: If after reset to the factory settings brakes remained, the problem may be in the hardware (wear flash memory, overheating of the processor.

How to prevent fast filling of cache?

To clear the cache on Redmi Note 7 less often, follow these tips:

• 📵 Limit background activity: in Settings → Battery → Battery Consumption Management Turn Off Autostart for Unnecessary Applications.
• 🚫 Use lightweight versions of apps: Facebook Lite, Messenger Lite, Twitter Lite take up less space.
• 🗃️ Set up automatic cleaning: in Settings → Warehouse → Clean up turn on the autoclean option.
• 🎮 Clean the cache of games manually: games type PUBG Call of Duty Mobile can take up to 1-2 GB of cache.
• 🌐 Use a browser with compression: Opera Mini or Chrome in traffic saving mode reduce the size of the cache.

You should also turn off auto-update apps in Google Play:

1. Open Play Store → Click on the profile avatar → Settings.
2. Select Network → Auto-Update Applications.
3. Set Do Not Update Automatically.

This will not only save space, but also reduce the load on the Snapdragon 660 processor, which is installed in the Redmi Note 7.
