How to speed up Xiaomi Redmi 6A to maximum performance: proven methods

Why Redmi 6A is slowing down and how to fix it

Xiaomi Redmi 6A — One of the most popular budget smartphones released in the 2018 Despite the modest characteristics of the year (4-nuclear-powered A22, 2 GB of RAM and 16/32 GB of memory, still in use, but over time, even the simplest tasks — launching messengers, watching videos or surfing the Internet — start to freeze. MIUI and obsolete firmware.

In this article, we’ll look at 7 proven ways to speed up the Redmi 6A, from basic settings to radical measures like flashing. It’s important to understand that budget hardware won’t become a flagship, but smart optimization will return the device to work at the 2020-2021 level.

If your smartphone is not just slowing down, but overheating, spontaneously rebooting or discharged in 2-3 hours, the problem may lie in a worn battery or damaged motherboard, in which case software methods will not help - you will need a diagnosis in the service center.

1. Cleaning up memory and cache: the first step to overclocking

The most common cause of brakes is clogged memory. On the Redmi 6A, with 16GB of storage, there is often less than 1GB of storage left, leading to system failures. Start with manual cleaning:

• 📁 Delete unnecessary files: Go to Settings → Storage and analyze what's taking up space. Pay special attention to the Download folders, DCIM (photo/video and WhatsApp/Media (chat-media).
• 🧹 Clear the application cache: in Settings → Annexes → All apps select heavy programs (e.g. Facebook, Instagram, YouTube) and click Clear Cache.
• 🗑️ Use a built-in cleaner: in MIUI There's a Cleanup tool, which deletes temporary files, remnants of deleted programs, and duplicates.

For deep cleaning, we recommend SD Maid (available on Google Play) that finds junk files that standard MIUI tools skip. Important: back up important data before using it, the program can delete files that seem system-like.

⚠️ Note: Do not manually clear the cache of system applications (e.g. com.android.systemui or com.miui.home) through Settings → All applications. This can cause interface failures. MIUI.

2. Disconnect background processes and autoboot

MIUI is known for aggressively holding apps in memory even when they're not in use, eating away at RAM and slowing down the system, to limit background activity:

1. Go to Settings → Battery and Performance → Battery Management.
2. Select Applications and mark programs that should not work in the background (such as games or rarely used utilities).
3. Activate the option to limit background activity.

Also, disable the autoload of unnecessary applications:

1. In Settings → Applications → Autorun, deactivate autoboot for all applications except system applications (e.g. Phone, Messages).
2. B Settings → Disable notifications from unnecessary services – they also consume resources.

For advanced users, ADB can turn off background activity at the system level, connect your smartphone to your PC, and follow the command:

adb shell cmd appops set <package_name> RUN_IN_BACKGROUND deny

Where <package_name> — Application ID (e.g. com.facebook.katana for Facebook) can be found via App Inspector or adb shell pm list packages.

3. Optimization of animation and MIUI interface

The visuals of MIUI are beautiful, but they inhibit the weak devices, and turning off the animations will speed up the system's response by 20 to 30 percent.

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find the items: Scale of window animation → No animation Scale of transition animation → No animation Duration of animation → Off.

We also recommend:

• 🎨 Switch to a lightweight launcher: install Nova Launcher or Lawnchair from Google Play. They consume less memory than the standard one. MIUI Launcher.
• 🖼️ Turn off live wallpaper: in Settings → Wallpaper select a static image.
• 🔍 Reduce the number of widgets on the desktop – they are constantly updated and load the processor.

⚠️ Attention: Disabling animations can make the interface less intuitive. For example, when you open applications, the screen will switch dramatically without a smooth transition. 0.5x shutdown.

Update of firmware: official and custom options

Outdated firmware is one of the main reasons for the brakes. Redmi 6A was officially supported before MIUI 12 on Android 9, but even these versions contain optimizations for weak devices.

1. Go to Settings → About the phone → System update.
2. If you have an update, install it. Importantly, charge your phone to 50 percent before you upgrade and connect to Wi-Fi.

If the official updates are no longer coming out, consider custom firmware.Popular options for Redmi 6A:

• 📱 LineageOS 16/17 (Android 9/10) — stable and lightweight firmware without excess software.
• ⚡ Havoc-OS – Optimized for weak devices, supports gestures.
• 🛠️ Pixel Experience – pure Android with features from Google Pixel.

Installing custom firmware requires unlocking the bootloader and having TWRP. This is a risky procedure - if you make a mistake, the phone can turn into a "brick." If you're a beginner, you'd better stop at the official firmware.

Hardware methods: replacement of thermopastes and batteries

If software methods have not worked, the problem may be overheating or a worn-out battery.The Redmi 6A is prone to overheating due to its compact body and weak cooling system.

• 🔥 The phone is heated even with light load (for example, in messengers).
• 🐢 Performance drops after 10-15 minutes of video or video.
• 🔋 Battery goes down in 2-3 hours with minimal use.

Decisions:

1. Thermopaste replacement: Over time, the factory thermopaste dries up and the processor begins to overheat. A new paste (for example, Arctic MX-4) will reduce the temperature by 5-10 ° C. The cost of the service is about 500-800 rubles.
2. Battery replacement: The capacity of the original 3000 mAh battery drops to 60-70% in 3-4 years. The new battery (original or high-quality analogue) will restore autonomy and reduce the slags from voltage drawdowns.

⚠️ Note: In the self-disassembly of Redmi 6A It is easy to damage the screen plumes or the power button. If you have never repaired your phones, you should contact the service. The average cost of replacing a battery is 1000-1500 rubles.

💡

Before replacing your battery, check the wear and tear of the battery through the AccuBattery app (available on Google Play). If the capacity has dropped below 70%, it's time to change the battery.

6 Radical measures: rollback to Android Go and root rights

If Redmi 6A is slowing down even after all the optimizations, there are two extreme options:

Option 1: Install Android Go

Android Go is a lightweight version of Android designed for weak devices, it consumes 30-40% less resources than standard MIUI. Redmi 6A has unofficial builds based on Android 10 Go or 11 Go.

Pros:

• ✅ Fast work even with 2 GB of RAM.
• ✅ Built-in lightweight versions of YouTube Go, Google Maps Go and other apps.

Cons:

• ❌ There are no functions MIUI (for example, the themes of design).
• ❌ Banking applications may not work (due to lack of certification).

Option 2: Getting root rights and deep optimization

Root access allows:

• 🚀 Remove system applications MIUI (Mi Video, Mi Music, Browser).
• 🔧 Configure the processor core for overclocking or energy saving.
• 🗑️ Completely clean the Dalvik cache and ART, speeding up the launch of applications.

To obtain root rights:

1. Unlock the bootloader through the official Xiaomi tool.
2. Install TWRP and run Magisk.
3. Use Titanium Backup or SD Maid to remove system debris.

⚠️ Note: Root rights take away your warranty (if it is still valid) and increase your risk of infection with viruses. Some applications (such as Sberbank Online or Google Pay) may stop working.

💡

Android Go is the best choice for the Redmi 6A if you want maximum performance without the risks of “bricking” the phone.

7.Alternative methods: cloud services and lightweight applications

If you can’t optimize your phone, transfer some tasks to the cloud or use lightweight analogues of popular programs:

Also consider cloud solutions:

• 🖥️ Microsoft Remote Desktop or TeamViewer – Managing a more powerful PC from your phone.
• 🎮 GeForce NOW Xbox Cloud Gaming – Games on Servers NVIDIA cellphone-free.
• 📁 Google Photos in the “Optimized Storage” mode – automatic photo / video compression.

These methods won’t speed up the phone itself, but will reduce the load on it by transferring the calculations to the servers.
