How to accelerate Xiaomi Redmi 6A in 2026: from simple customization to deep optimization

The Xiaomi Redmi 6A, released in 2018, is still a popular budget smartphone due to its reliability and maintainability. However, every year owners face the same problem: the device begins to “brake”, applications open for a long time, and the MIUI interface works with delays. The reasons can be different from overloaded memory to outdated firmware, but the good news is that 90% of problems are solved without replacing iron.

In this article, we’ll look at 7 working ways to speed up the Redmi 6A, from basic settings to advanced tricks that even service engineers use. It’s important to understand that the budget MediaTek Helio A22 processor and 2GB of RAM impose restrictions, but the right optimization can restore the smartphone to its former briskness. We’ll also explain what actions can harm the device (for example, uncontrolled cache cleaning or installing questionable “accelerators”), and give a checklist for safe settings.

If your Redmi 6A is slower after the MIUI update, it freezes when the camera or games start, and the battery goes down in a few hours — this is the guide for you. Let's start with the simplest methods and gradually move on to more complex ones.

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

The most common cause of brakes is clogged memory. The Redmi 6A only has 16 or 32 GB of internal storage, and if it's less than 10% free, the system starts to "glut," and even if you haven't installed many applications, temporary files, cache and debris take up critical volumes over time.

Start with manual cleaning:

• 📁 Remove unnecessary photos and videos (especially in the DCIM/.thumbnails — It's a place where you can store miniatures that can weigh gigabytes).
• 🗑️ Clean the Recycle Bin in the Gallery and File Manager (it takes up space until manually cleaned!).
• 🧹 Use the built-in Cleanup tool (the broom icon in the Security menu) to find garbage, duplicates and large files.
• 🔄 Move heavy files (movies, music) to a microSD (if the card is installed). But remember: applications from the memory card are slower!

For deep cache cleaning:

1. Go to Settings → Applications → Application Management.
2. Sort the list by size (click on the three dots in the upper right corner).
3. Select apps with large cache (e.g. YouTube, Facebook, Google Play Services) and click Clear Cache.
4. Do not clear the data (Clear Data button) – this will delete accounts and settings!

⚠️ Warning: Do not use cleaners like Clean Master or CCleaner. They often delete important system files, causing crashes. MIUI enough.

2. Disable animation and visual effects

MIUI is known for its beautiful animations, but on the weak hardware of the Redmi 6A, they only slow down the interface. Turning off unnecessary effects can speed up work by 15-20%.

How to do this:

1. Activate Developer Mode: Go to Settings → About Phone. Click 7 times on the MIUI Version until the “You’re a Developer” notification appears.

Settings → Additional → For Developers

Window animation

Animation of transitions

Duration of animation

No animation.

0.5x

We also recommend that you disable:

• 🌈 Themes and wallpapers with animation (use static pictures).
• 🔄 Auto-update the weather widget (it consumes resources in the background).
• 🎨 Unlocking effects (in Settings) → Lock screen).

These changes don't require a reboot and will immediately work, and the interface will be less glamorous, but noticeably faster.

💡

If after disabling the animation, the screen started twitching when scrolling, try to return the value of 0.5x - this is a compromise between speed and smoothness.

3. Optimization of autoboot and background processes

Many apps run automatically when the phone is turned on and run in the background, consuming RAM and battery power. On the Redmi 6A with 2GB of storage, this is critical.

How to limit autoloading:

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Facebook or VK).
3. Press AutoRun and turn it off.
4. Repeat for all unnecessary programs (especially messengers and social networks).

To limit background activity:

• 🛑 In the same app management menu, find Background Limitation and turn it on for "gluttonous" programs.
• 🔋 B Settings → Battery → Battery mode select Charge Savings – this will automatically limit background activity.
• 📵 Turn off auto sync for unnecessary accounts (such as Google Photos or Weather) in Settings → Accounts.

⚠️ Note: Do not disable auto-start for system applications (e.g, MIUI Security or Google Services Framework.This can cause phone malfunctions.

4. Resetting to factory settings: a radical method

If previous methods didn’t help and the phone is still slowing down, a full reset could bring it back to speed.This will delete all data, so be sure to back up!

How to reset Redmi 6A:

1. Go to Settings → About the phone → Reset settings.
2. Select Reset All Settings (not to be confused with Network Resettings!).
3. Confirm the action and wait for the reboot (it will take 5-10 minutes).

After discharge:

• 🔄 Don’t restore all data from the backup at once – it will boot the system again.
• 📥 Install applications selectively (only those that are really needed).
• 🔧 Set up your phone according to the instructions in the first three sections of this article.

Resetting helps in 80% of cases when the brakes are caused by software errors, not hardware. If after this procedure the problem remains - the reason is in the hardware (for example, worn flash memory).

💡

Factory reset is the most effective way to eliminate software brakes, but it takes time to reset the phone. Use it if other methods have not worked.

5. Firmware Update: Relevance = Stability

Xiaomi regularly releases updates for MIUI that optimize the experience on older devices. However, many users turn off auto-updates for fear of “breaking” the phone. On Redmi 6A, this is a mistake: fresh firmware versions often contain fixes for lags and bugs.

How to update the firmware safely:

1. Go to Settings → About the phone → System update.
2. Click Check for updates.
3. If you have a new version, download it (preferably via Wi-Fi).
4. Before installing, make sure that the battery is >50%.

If the update doesn't come in:

• 🌍 Check the firmware region. 6A Global (for international devices) and Russia (for official Russian models) are suitable).
• 🔧 Use Mi Community or en.miui.com to manually download firmware (for power users only!).
• 🚫 Do not install custom firmware (such as LineageOS) – this can lead to loss IMEI or camera problems.

⚠️ Warning: If the phone brakes even more after the upgrade, reset to factory settings (section 4). MIUI require a “clean” installation.

6. Advanced methods: for experienced users

If the standard methods didn't work, you can try more radical measures. They require technical knowledge, but can significantly speed up the Redmi 6A.

Method 1: Disable MIUI Optimization (Android 9+ only)

Some versions of MIUI have a hidden feature that artificially limits performance to turn it off:

1. Activate the developer mode (see section 2).


2. Go to For Developers.




3. Find the MIUI Optimization option and turn it off.




4. Reboot the phone.

⚠️ This can cause some functions (such as themes or gestures) to fail. If you have problems, return the settings back.

Method 2: Installation of lightweight firmware

Redmi 6A has modified firmware without any software (e.g. MIUI Lite) and can be found on forums like 4PDA or XDA Developers.

• 🔧 Requires unlocking the bootloader (bootloader).
• 🛠️ You need to have skills with Fastboot and ADB.
• 🚨 The risk of “bricking” the phone (turning into a “brick»).

Method 3: Replace the heat paste (if the phone overheats)

Over time, the heat paste between the processor and the radiator dries up, leading to trottling (automatic performance loss due to overheating). If the phone heats up a lot even under low load, you can:

• 🔩 Carefully disassemble the device and apply a new thermal paste (e.g. Arctic) MX-4).
• 🌡️ Use a cooling cover or stand.
• 📉 Disable turbo mode in games (in Settings) → Special facilities → Game mode).

1. Download the official firmware from the Xiaomi website (only for your model!)

2. Install ADB/Fastboot drivers on PC

3. Unlock the bootloader via Mi Unlock Tool (requires Mi Account binding)

4. back up the data (firmware will delete everything!)

5. charge the phone at least 70%-->

7. Hardware causes of brakes: when it's time to go to service

If none of the software methods worked, the problem could be the hardware. Here are the typical hardware faults of the Redmi 6A that cause the brakes:

• 💾 Flash memory wear (especially if the phone often reboots or “forgets” settings). Solution: Replacing the memory chip (expensive, often impractical).
• 🔋 Bloated battery (presses on motherboard causing crashes). Solution: battery replacement (costs) ~1000-1500 rubles.).
• 📶 Problems with the antenna (phone "brakes" at a weak signal of the network) Solution: replacement of the antenna module or checking the SIM card.
• 🔌 Oxidation of contacts (for example, after moisture) Solution: cleaning with alcohol or ultrasonic bath in the service.

How to check for hardware problems:

1. Run the iron test through the engineering menu: ##4636## → Equipment Testing (not working on all versions of MIUI).
2. Check the battery status in Settings → Battery → Battery status. If the capacity has dropped below 70%, it's time to change.
3. Connect your phone to your PC and check your read/write speed with CrystalDiskMark (norm for Redmi 6A: ~100-150MB/s).

⚠️ Warning: If the phone falls or gets wet, don't try to repair it yourself.Corrode on the board can short circuit and completely fail.
