Xiaomi Redmi 7, released in 2019, still remains a popular budget smartphone thanks to its reliable hardware: processor Snapdragon 632, 2–4 GB of RAM and a battery 4000 mAh. However, over the years, even such a device begins to “slow down” - applications take a long time to open, animations twitch, and the system freezes. The reason for this is not only the aging of components, but also background processes and outdated settings. clogged MIUI firmware, background processes and outdated settings.

In this article - 7 proven ways to speed up Redmi 7 without buying a new phone. We will analyze both software methods (clearing the cache, disabling animation) and radical ones (resetting to factory settings and flashing). All instructions are adapted for MIUI 10–14 and relevant for models with Android 9 Pie or Android 10 Q.

⚠️ Important: some methods (for example, overclocking the processor or manually removing system applications) can lead to unstable operation of the phone. If you are not sure of your actions, limit yourself to the safe methods from the first three sections.

1. Clearing garbage and cache: the first step to speed

The most common cause of slowdowns is full storage a clogged cache. On Redmi 7 with 32 or 64 GB of memory this is especially critical: the system begins to “choke” when less than 10% of the space is free. Let's start with basic cleaning:

📌 How to check free space?

Go to Settings → About phone → Storage. If there is less than 3–5 GB in the “Available” section, it’s time to clean it.

  • 🧹 Clearing the application cache: go to Settings → Applications → Manage applications, select any application (for example, Chrome or Facebook) and click "Clear cache". Repeat for 10–15 of the heaviest apps.
  • 🗑️ Removing unnecessary files: use the built-in application Cleaning (broom icon) or third-party utilities like CCleaner. Pay attention to folders Download, DCIM (photo/video) and WhatsApp/Media.
  • 📂 Transfer data to the memory card: if you have a microSD installed, move photos, music and documents to it via Files → Categories → Select → Move.

⚠️ Attention: do not clear the cache of system applications (for example com.android.systemui) - this may lead to interface failures. Also avoid “optimizers” from Google Playthat promise to “speed up your phone by 300%” - most of them can be trusted no more than casino advertising.

2. Disabling animation and visual effects

MIUI is known for its “beauty”: smooth transitions, animations when opening applications, blur effects. But Redmi 7 with its modest 2–3 GB of RAM, these “beauties” only slow down the system. Let's disable them:

🔧 How to remove animation in MIUI:

  1. Activate Developer mode: go to Settings → About phone and tap on “MIUI Version” 7 times. A notification “You have become a developer” will appear.
  2. Return to Settings → Advanced → For developers.
  3. Find three items:
    • Window animation scale → select Without animation;
    • Transition animation scale → Without animation;
    • Animation duration → Off.

🎨 Disable unnecessary visual effects:

In the same settings for developers, find:

  • 🖼️ Disable hardware acceleration — do not touch (this will worsen performance);
  • 🌈 Turn off background blur → enable;
  • 📱 Disable microapplications → enable (this will remove unnecessary widgets on the desktop).

💡

If, after turning off the animation, the phone begins to appear "sharp", return the animation scale to 0.5x - this is a compromise between speed and smoothness.

3. Optimizing startup and background processes

One ​​of the main reasons for slowdowns is applications that launch when the phone is turned on hanging in the background, consuming RAM. On Redmi 7 with its 2–3 GB of memory this is critical. Let's take a look at how to limit startup:

🚀 How to disable startup:

  1. Go to Settings → Applications → Manage applications → Autoload.
  2. Sort the list by date of last use (tap on the three dots in the upper right corner).
  3. Disable autoload for all applications except:
    • 📱 System (Google Play Services, MIUI Daemon);
    • 🔒 Messengers (WhatsApp, Telegram - if you need them immediately after turning it on);
    • 🔔 Applications with notifications (for example, Mail or Calendar).

🔄 Limit background activity:

In the same application settings, find the item Battery → Battery optimization. Here you can manually limit background work for “gluttonous” apps:

  • 🎮 Games (PUBG, Call of Duty —they do not need to work in the background);
  • 🛒 Social networks (Facebook, Instagram —they constantly synchronize data);
  • 📊 Analytics (Google Analytics, Firebase — often built into applications and slow down the system).

4. Reset to factory settings: radical. method

If the phone slows down even after cleaning and optimization, the problem may be accumulated errors. system. In this case, resetting to factory settings will help. This will delete all data, but return the phone to its “original speed.” Hard Reset - reset to factory settings. This will erase all data but return the phone to its "original speed".

⚠️ Attention: Before resetting, be sure to:

  • 🔐 Make a backup copy of your contacts (Contacts → Settings → Import/Export);
  • ☁️ Synchronize photos with Google Photos or Mi Cloud;
  • 📝 Write down logins/passwords for important accounts (they will be erased!).

🔧 How to do a Hard Reset on Redmi 7:

  1. Go to Settings → About phone → Reset settings.
  2. Select Erase all data (factory reset).
  3. Enter the password (if set) and confirm the action.
  4. Wait for the reboot (it will take 5-10 minutes).

💡 What to do after the reset?

  • ❌ Do not restore data from the backup copy MIUI —it may contain the same errors;
  • ✅ Install applications selectively (only the most necessary);
  • 🔄 Immediately disable autoloading and animation (see sections 2 and 3).

What happens if you interrupt the reset?

If you turn off the phone during Hard Reset (for example, by removing the battery), there is a risk of damaging system files. In the best case, the phone will freeze on the logo Redmi, in the worst case, it will require flashing via Fastboot. If the reset takes longer than 15 minutes, wait until the battery is low or contact service.

5. and Android

Outdated firmware is one of the reasons for the brakes. Xiaomi regularly releases updates for Redmi 7that correct errors and optimize performance: Check the relevance of your version:

📲 How to update MIUI:
