Cache Clearing on Xiaomi Redmi 7: 5 Ways to Free Memory and Speed Up Your Smartphone

Xiaomi Redmi 7 will slow down, slow down, or suddenly reboot over time? 90% of the time, the problem is with crowded cache, which is temporary files that the system and programs accumulate as they work, and the cache is used to speed up repeat operations, but when it exceeds 1-2 GB, it turns into digital garbage, which eats up performance.

In this article, you will find 5 proven ways to clean up Redmi 7 cache, from standard MIUI tools to hidden features for power users, how to remove individual applications cache, system cache (including Dalvik), and even how to automate the process so you don’t have to go back to it every week. All methods are tested on current versions of MIUI (including MIUI 14) and do not require root rights.

Important: Cache cleaning is not a panacea for all problems. If the phone keeps lagging after the procedure, check the RAM load (in Settings → Phone → System Status) or consider resetting to factory settings. But in most cases, competent cache cleaning returns the Redmi 7 to factory speed.

1.What is cache and why should it be cleaned on Redmi 7

Cache is a temporary file that creates apps and a system to speed things up. For example, when you first open Instagram, it uploads profile photos to cache, and the next time it runs, it takes that data from the phone's memory, rather than downloading it again, saving traffic and time.

The problem is that over time, the cache grows to giant sizes. On Redmi 7 with 32 GB of memory, users often find that the cache takes up to 4-5 GB, which is almost 15% of the total volume, and some files become “bitten”: applications do not use them, but they are not deleted automatically.

• 📱 Cache of applications: temporary data of games, social networks, instant messengers (for example, thumbnails of photos in the video). VK or cache of cards in Google Maps).
• 🖥️ System cache: files MIUI, Android cores and Google services (takes hundreds of megabytes).
• 🔄 Dalvik-cache: Optimized versions of apps for fast download (you can only remove via Recovery).

When the cache is full, Redmi 7 starts:

• ⏳ Long to open applications (especially after updating) MIUI).
• 🔋 Discharge quickly – the system spends resources on processing unnecessary files.
• 📉 «Fly out of games or social networks with the error “Not enough memory».
• 🔄 Reboot spontaneously when filling the internal drive.

⚠️ Warning: Don't confuse cache with user data! Cache clearing won't delete your photos, messages, or saves in games. But after the procedure, some apps (like YouTube or Tinder) can take longer to load on the first run - that's okay.

2. Method 1: Clearing the cache of individual applications through settings

The easiest and safest method is to remove the cache for specific programs, which is useful if only one application (such as WhatsApp or the Play Store) is slowed down.

Instructions:

1. Open Settings → Applications → Application Management.
2. Slip on the right app (for example, Facebook).
3. Select Warehouse. → Clear the cache.
4. To clean up completely, click Space Management → delete unnecessary files (e.g. uploaded videos to Telegram).

How much space can I get? Depends on the app.

Tip: sort applications by cache size. To do this, click on the three dots in the upper right corner of Application Management → Sort → By size. So you quickly find the main memory eaters.

Close the application in multitasking

Connect your phone to charge (if the battery level is < 20%)

Backup important data (e.g. game saves)

Check the available space on the phone (needs at least 500 MB)

-->

⚠️ Note: Do not clear the cache of system applications (e.g. com.android.systemui or MiuiHome) unnecessarily. MIUI, including the disappearance of icons from the desktop or errors when unlocking.

Method 3: Automatically clean the cache through “Security”

• 🧹 Does not clean Dalvik-cache and some system files.
• 📉 Can delete the cache of useful applications (for example, offline maps in Yandex.Navigator).

After cleaning, restart the phone, which will help MIUI recalculate the free space and apply changes. If the storage space in the Storage section (in the settings) has not changed, repeat the procedure or use method 3.

Method 3: Clean the system cache through Recovery Mode

This method is suitable for advanced users. It deletes all temporary system files, including the MIUI update cache, Dalvik-cache and residual data of remote applications. Redmi 7 after this cleanup works noticeably faster, but the procedure requires you to enter Recovery mode.

• 📱 The phone is slowing down after the update. MIUI.
• 🔄 Applications are constantly crashing with the error “App is stopped».
• 📉 Free disk space decreases by itself (virus or system failure).

7.How often do you need to clean the cache on Redmi 7

The cleaning frequency depends on how you use your phone. Here are the general guidelines:

• 📱 Ordinary users (social networks, instant messengers, calls): every 1-2 months.
• 🎮 Gamers (games like this) PUBG, Genshin Impact: Every 2-3 weeks (games actively caching textures).
• 📸 Photographers/videographers: once a month (camera and galleries are growing fast).
• 🔧 After updating MIUI: You must clean the cache through Recovery!

Signs that it is time to clean the cache:

• 🐢 Phone "hangs" when opening applications.
• 📉 In storage settings less than 1 GB of free space.
• 🔄 Applications are closed spontaneously.
• 🔋 Battery goes down 20-30% faster than usual.

Automating the process will help:

• 🤖 Built-in planner in Security (set up weekly cleaning).
• 📅 Planned tasks in SD Maid (requires a premium version).

8. Frequent errors in cleaning the cache and how to avoid them

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

1. Cache removal for com.android.phone (calls), com.miui.home (launcher) or com.google.android.gms (Google services) can lead to: 📞 Disappearing call history. 🏠 Resetting wallpaper and widgets on the desktop. 🔍 Google account sync errors Solution: Don't touch system apps unnecessarily. If you need to clear them, use Recovery.
2. Frequent cache cleaning (once a day) Constantly removing the cache causes applications to reload data every time that: 📶 Increases traffic consumption (up to 500 MB per day). ⏳ Slows down the first start of programs. 🔋 Increases the load on the processor (and therefore battery consumption).

Solution: Clean the cache no more than 1 time every 2 weeks unless there is a critical need.

Using “cleaners” with aggressive algorithms

Applications like Clean Master or DU Speed Booster often remove not only cache, but also:

• 📂 Application configuration files (settings reset).
• 📥 Updates uploaded MIUI (I'll have to re-download).
• 🔑 Authorization data (you have to re-enter logins / passwords).

If you have problems after cleaning the cache, try:

• 🔄 Reboot your phone (solves 80% of the problems).
• 📥 Reinstall the "glutty" application.
• 🛠️ Reset the application settings (in Settings) → Annexes → [name] → Warehouse → Reset).
