How to increase the performance of Xiaomi Redmi 7: from basic settings to hidden chips MIUI

Xiaomi Redmi 7, released in 2019, still remains a popular budget smartphone due to the balanced “iron” stuffing: Snapdragon 632 processor, 2-4 GB of RAM and a battery of 4000 mAh. MIUI And even this reliable device starts to slow down, slowly open applications and overheat, unlike flagships, where the margin of performance is put in place, budget models require regular optimization.

In this article — 12 Proven ways to increase the speed of Redmi 7 without the risk of bricking or loss of warranty. MIUI 12/14, and little-known chips (including overclocking) GPU through the engineering menu and shutdown MIUI All methods tested on Global Stable firmware and EEA — no-custom-recovery and root-rights.

We will pay special attention to the problem of “hangs” after updating to the MIUI 14 on Redmi 7 — that's due to the unoptimized Linux 3.18 kernel for newer versions of the shell. If your phone is slower after the software upgrade, in the firmware section, you'll find a solution that rolls back to a stable version.

1.Diagnostics of current performance

Before you optimize the Redmi 7, you need to understand what's stopping it, and 80 percent of the time, it's just on the surface.

• 📱 RAM loading - background processes MIUI (For example, com.miui.analytics can take up to 1 GB of memory.
• 🗑️ Covered cache - system partition /cache Dalvik-cache applications are fragmented over time.
• 🔋 Energy saving regime — MIUI aggressively restricts clock frequency CPU charge level below 15%.
• 🔄 The old firmware is in MIUI 12.5+ Memory management bugs for Snapdragon 632.

For accurate diagnosis, use:

1. Built-in system monitor: go to Settings → The phone. → Version. MIUI and slip 7 Once on the core (the menu will open) CIT load-chart CPU/GPU).
2. Annex CPU Throttling Test (to show whether the system limits the clock frequency).

⚠️ Attention: If in CIT schedule GPU It sticks 100% constantly, which is a sign of overheating. First clean the phone of dust (especially the charging connector), and then optimize the software.

System cleanup: from cache to digital garbage

The first step to speed up is to free up space and delete unnecessary data. On Redmi 7 with 32 GB of memory, it is critical to keep at least 4-5 GB free, otherwise the system starts to “dump” the application cache into the swap (virtual memory), which slows down the work.

Clearing the cache and Dalvik-cache

The cache of the apps and the Dalvik-cache of the Android virtual machine become fragmented over time, and cleaning them up gives you an increase in speed of up to 15-20%:

• 🧹 Standard method: Settings → Warehouse → Clear the cache (but it doesn't affect Dalvik).
• 🔧 Using Recovery: Turn off the phone. Click the power. + Volume up before the Mi logo appears. Select Wipe & Reset → Wipe Cache (not to be confused with Wipe Data!).

Through ADB

adb shell


su




rm -r /data/dalvik-cache/*




reboot

System debris disposal

MIUI leaves behind temporary files, logs and duplicate media to delete them:

1. Use Files by Google (Cleanup tab) → Unnecessary files).
2. Delete the folders: /sdcard/DCIM/.thumbnails (photo-sketch) /sdcard/MIUI/debug_log (logistic) /sdcard/Android/data/com.xiaomi.midrop/* (Mi Drop cache)

miniature

Gallery settings → Additionally. → Miniatures

Optimization of the storage facility

If there's less than 10 percent of the space available, Android starts to swap data, which slows down the system.

⚠️ Warning: Don't use cleaners like Clean Master, they cause the brakes by triggering the background. Redmi 7 has enough built-in tools. MIUI Files by Google.

3. set up MIUI for maximum performance

MIUI It's optimized by default to balance performance and battery life, but for the Redmi 7, you can manually disable unnecessary resource-eating chips.

3.1. Disable animations and visual effects

Transition animations and effects MIUI They look beautiful, but they slow down the processors, to speed up the interface:

1. Activate Developer Mode: Settings → About Phone → MIUI version (tap 7 times).
2. Back to Settings → Additionally. → For developers and set: The scale of the animation window → Off. Scale of transition animation → Duration of animation → 0.5x (or off.)

blurring

Settings → Screen → Effects of animation

No animation.

These changes will remove delays when opening apps and switching between them, such as YouTube launching 0.5-1 second faster.

Optimization of background activity

MIUI aggressively caches apps, even those you don't use, to limit background activity:

• 🚫 Autostart Limitation: Settings → Annexes → Application management → Autorun. Turn off autorun for all applications except instant messengers and system services.
• ⚡ Battery optimization (indirectly impacts performance): Settings → Battery → Select Battery Mode. Select Performance (instead of Balanced).

Hand-cleaning RAM

Cleaning up memory

Widgets → Cleaning up memory

💡

If after the auto-start restriction, notifications from the VK or Telegram, add these apps to exceptions: Settings → Annexes → Permits → Auto-start → Exceptions.

3.3 Disconnecting unnecessary system services

MIUI It runs analytics, advertising, and cloud sync services by default, and can be safely disabled:

After disabling these services, up to 200-300 MB of RAM will be free, and the background activity of the processor will decrease by 5-10%.

💡

Disabling com.miui.analytics not only speeds up the system, but also reduces traffic consumption in the background (up to 50 MB per month).

4. Overclocking and optimizing iron (without root)

Even without root rights on Redmi 7 can increase the clock frequency GPU Optimize the processor through hidden settings MIUI.

4.1 Acceleration GPU through the engineering menu

The Adreno 506 processor in the Snapdragon 632 defaults to 650 MHz, but it can be increased to 710 MHz:

1. Open the engineering menu: ##4636### Select Phone Information.
2. Scroll down to Set. GPU default frequency.
3. Set the value of 710,000 (710 MHz).
4. Save and restart the phone.

That would add to the 3D-games (e.g. in the PUBG Mobile FPS But you'll get a lot more heat -- watch the temperature through the window. AIDA64.

⚠️ Note: If after acceleration GPU The phone starts to overheat above 50.°C (check in) AIDA64), Return the standard frequency (650,000) and prolonged overheating reduces battery life.

Optimization of the scheduler CPU

By default. MIUI The CFQ (Completely Fair Queuing) scheduler is not always optimal for the Snapdragon 632, and you can switch to BFQ (Budget Fair Queuing) for better responsiveness:

1. Install Kernel Adiutor (no root required)
2. Open the CPU → I/O scheduler.
3. Select bfq and apply.
4. Reboot the phone.

This will reduce delays when opening heavy apps (e.g. Chrome from 10)+ tabs) by 10-15%.

4.3. Shutdown MIUI Optimizations

MIUI Optimizations are a set of background processes that supposedly "improve" the system, but in practice often slow it down:

1. Activate. ADB (Turn on Debugging. USB developer-setting).
2. Connect your phone to your PC and execute the command: adb shell pm disable-user --user 0 com.miui.powerkeeper pm disable-user --user 0 com.miui.securitycenter pm disable-user --user 0 com.miui.analytics
3. Reset the device.

And then the scroll lags disappear and multitasking speeds up. MIUI, for example:

• 🔋 Automatic battery optimization.
• 🛡️ Built-in antivirus.
• 📊 Application usage statistics.

5. Update and roll back firmware

One of the main reasons for the Redmi brakes 7 — flat-fib MIUI 13/14 for Snapdragon 632. Xiaomi officially stopped supporting the device, but you can manually install a stable version.

5.1 How to check the current version MIUI

Go to Settings. → The phone. → Version. MIUI. If you:

• 🟢 MIUI 12.5 - The best option (stable and fast).
• 🟡 MIUI 13 - possible lags with animations.
• 🔴 MIUI 14 – High probability of brakes (especially in games).

5.2. Recoil to MIUI 12.5

If you have a Redmi. 7 renewed MIUI 13/14 And you start to slow down, come back on. 12.5:

1. Download the official firmware for Redmi 7 (select Global region or EEA, version 12.5.7.0).
2. Rename the file to update.zip and place it in the root of the phone’s memory.
3. Press Power + Volume Up to Enter Recovery.
4. Select Install update.zip and wait until it is completed.

After the rollback:

• 🔄 Turn off auto-update: Settings → The phone. → Updating the system → Three points. → Settings → Auto-update.
• 📵 Delete the folder. /cache via Recovery (p. 2.1).

⚠️ Note: When you roll back the firmware, all data (photos, apps, settings) will be reset. → Additionally. → Backup.

5.3. Alternative firmware (for advanced)

If you are willing to take risks, you can install custom firmware based on Android 10/11:

The installation will require:

1. Unlock bootloader (via Mi Unlock Tool)
2. Install TWRP Recovery (Redmi version) 7 — twrp-3.7.0_9-0-onclite).
3. Switch firmware and GApps (if you need Google services).

💡

Custom firmware can increase performance by up to 40%, but it is not warranty and can cause problems with the camera or mobile network.

6. Battery and cooling optimization

Overheating and battery settings are common causes of trottling (automatically lowering the CPU frequency). On Redmi 7, this manifests as sudden "suspends" in games or when charging.

Calibration of the battery

If the phone suddenly turns off at 20-30% charge, you need to calibrate:

1. Discharge the phone to 0% (until it shuts down).
2. Charge to 100% without interruptions (use the original power supply).
3. Turn off the charger and wait for 0% again.
4. Repeat the charging-discharge cycle 2-3 times.

It'll dump the data. BMS (battery control system) and return accurate charge readings.

Calibration of cooling

To prevent trolling:

• 🧊 Limit charging to 80% (extends battery life): adb shell dumpsys battery set ac 1 dumpsys battery set usb 1 dumpsys battery set limit 80 (reset after restarting).
• 🌡️ Use a cooling stand when playing games (e.g. Black Shark Cooler).
• 🔄 Turn off fast charging (if the phone is warming): Settings → Battery → Fast charging.

Replacement of thermopaste (for extreme cases)

If Redmi 7 warms up even in simple (above 45)°C, maybe the heat paste has dried up:

1. Disassemble the phone (you need a plastic transmitter and a screwdriver). T3).
2. Remove the metal plate from the processor.
3. Remove the old paste with alcohol, apply a new one (e.g. Arctic) MX-4).
4. Get your phone together, check the temperature in AIDA64.

⚠️ Warning: Disassembly of the phone is not warranty. If you are not confident in your abilities, contact the service center. The average cost of replacing the thermopaste is 800-1200 rubles.

7.Alternative launchers and lightweight applications

Standard launcher MIUI It consumes up to 300-400 MB of RAM, even when you're not using it, and replacing it with a lightweight one will speed up the interface.

7.1 Best launchers for Redmi 7

For maximum performance, choose Poco Launcher – it consumes the least resources and has no unnecessary animations.

7.2 Lightweight versions of applications

Replacing the “heavy” applications on the Lite version will free up to 500 MB of RAM:

• 📱 Facebook → Facebook Lite (saves 100MB of RAM).
• 💬 Messenger → Messenger Lite.
• 🌐 Chrome → Chrome Lite (Bromite) or Firefox Focus.
• 📷 Instagram → Web version via Hermit Lite Apps.

Disconnecting widgets and live wallpaper

Widgets and animated wallpaper are constantly consumed CPU/GPU. To turn them off:

• Keep your finger on the main screen. → Wallpaper settings → Choose Static.
• Remove all widgets (such as weather or calendar).
• Turn off the effects of paralax: Settings → Screen. → Wallpaper effects.

💡

If you use Nova Launcher, disable the Smooth Scrolling option in its settings – this will reduce the load on the platform. GPU.

8. Radical methods (if nothing has worked)

If all of the above methods have not yielded results, extreme measures remain:

8.1 Reset to factory settings

A complete reset will delete all data, but it will return the phone to its "clean" state.

1. Save important data (photos, contacts, SMS).
2. Go to Settings → Additional → Resetting settings.
3. Choose to erase all data and confirm.

After discharge:

• Do not restore backup via Mi Cloud – it may contain old settings that slow down the system.
• U
