How to speed up Xiaomi Redmi 6A: From simple customization to deep optimization

Xiaomi Redmi 6A It is still one of the most popular budget smartphones due to its reliability and maintainability, but over the years, even this “unkillable” device begins to slow down: apps open long, animations twitch, and the system hangs when multitasking. This is due to the weak Helio processor. A22, It's only 2GB of RAM and memory, but don't be too quick to write it off!

In this article, we will discuss 10 Proven ways to speed up Redmi 6A — basic MIUI They're all up to little-known firmware tricks, all of which are tested on current versions. MIUI 12/14 You'll learn how to free up memory without losing data, disable unnecessary Xiaomi services, and even make your smartphone run faster with hardware features. 15-20% via hidden kernel settings (only working on Redmi) 6A!).

Important: before optimizing, check the battery power - all manipulations with the system are better done at a level of at least 40%. → Additionally. → Backup.

1. Diagnosis of the current state: what exactly is inhibiting?

Before you start optimizing, you need to identify the "bottlenecks." - Redmi 6A It can slow down for three main reasons:

• 📱 Lack of RAM — MIUI Actively uses background processes, and 2 GB of RAM is quickly clogged.
• 🗑️ Burdened internal memory – application cache, remnants of deleted programs and duplicate files take up precious space.
• 🔄 Outdated firmware - new versions MIUI Optimized better, but require more resources.

To understand what is slowing down your smartphone:

1. Open Settings → About Phone → MIUI version and check the relevance of the firmware.
2. Go to Settings. → Annexes → System status and see the RAM usage schedule.
3. Install the CPU Monitor app (from Google Play) and check to boot the processor to plain.

If free RAM is less than 300 MB, and the processor is loaded to 20 MB%+ No active tasks, your Redmi 6A If the brakes only appear in specific applications (such as games or Facebook), the problem may be optimizing them, read the app settings section.

⚠️ Note: If the smartphone brakes immediately after turning on (even before unlocking the screen), this may indicate damage to the file system, in which case only resetting to factory settings or flashing through Fastboot will help.

2. Cleaning up garbage: freeing up memory correctly

The first and most obvious step is to free up internal memory, but simply removing unnecessary files is not enough: clearing the system cache, application residues and duplicate media files.

Step 1. Cleaning the app cache

Go to Settings. → Annexes → All apps, select the hardest (like Facebook, Instagram or Google Chrome) and click Clear Cache:

Settings → Memory → Waste Cleanup → Deep Cleanup

It'll be deleted before 1-3 GB of unnecessary data without losing personal information.

Step 2: Remove duplicates and unnecessary files

Download the Files by Google app (it's lighter than the standard one) MIUI File Manager) and use the Cleanup function → Duplicate files. Pay special attention to folders:

• 📁 DCIM/.thumbnails — Photos that can weigh hundreds of megabytes.
• 📁 Downloads – unnecessary items are often accumulated here APK documents.
• 📁 Android/obb — game cache, PUBG Mobile or Call of Duty can take up to 2 GB).

Step 3: Transfer of data to SD-map

Redmi 6A Supports memory cards up to 256GB, but by default, applications are installed in internal memory:

Settings → Appendices → Select Appendix → Memory → Modify → SD-map

Note that not all apps support portability, and you can manually move media files (photos, videos, music) to the root. SD-Cards through any file manager.

⚠️ Note: Do not manually delete files from folders /system or /vendor — This can cause your smartphone to fail. For deep cleaning of system partitions, use only official tools. MIUI or ADB.

3. MIUI Optimization: Disabling Unnecessary Functions

MIUI — One of the heaviest shells for weak smartphones, with lots of background processes, animations and services that you can turn off without losing functionality. 6A:

Shutdown of animations

The transition animations and the opening of applications eat up the CPU resources to speed them up:

Settings → About Phone → MIUI Version (shoot 7 times to turn on Developer Mode)


Settings → Additional → For developers → Animation speed (set 0.5x or turn off)

Background activity shutdown

Many apps continue to work in the background even when you're not using them.

Settings → Battery and Performance → Battery Management → Select App → Limit background activity

Pay particular attention to:

• 📱 Messengers (WhatsApp, Telegram, Viber) – they constantly synchronize data.
• 🌍 Social networks (Facebook, Instagram, TikTok) – consume RAM even in a folded state.
• 📍 Geolocation services (Google Maps, Yandex.Maps) – constantly refer to the GPS.

Disconnection of Xiaomi services

Xiaomi is embedding in MIUI A lot of unnecessary services that can be safely turned off:

Settings → Applications → All applications → Three points (menu) → Show system

Find and disable (or stop) the following services:

• 🔍 com.miui.analytics – collection of statistics on the use of.
• 📊 com.xiaomi.midrop - file transfer service (analogue of AirDrop).
• 🎵 com.android.musicfx – equalizer (if not used).
• 📡 com.xiaomi.xmsf – sync service (you can turn off if you do not use the Mi Cloud).

After disabling these services, restart your smartphone. You will notice that it began to boot faster, and free RAM became available on the phone. 100-150 More MB.

💡

If errors appear after disabling system applications (for example, the camera does not work), return them to the original state through Settings. → Annexes → Three points. → Resetting application settings.

4. Application configuration: which can be “facilitated”?

Even after the memory is cleared, some applications continue to slow down, which is due to their optimization for weak devices.

Use of lightweight versions (Lite)

For Redmi. 6A It is better to install lightweight versions of popular applications:

• 📘 Facebook Lite instead of Facebook (saves up to 50% RAM).
• 📷 Instagram Lite – weighs only 2 MB against 50 MB in the regular version.
• 🎵 Spotify Lite or YouTube Go for listening to music and videos.
• 🗺️ Google Maps Go – a simplified version of maps.

Disabling Auto-Run Applications

Many programs are automatically triggered when you turn on your smartphone or connect to the Internet, to fix this:

Settings → Battery and Performance → Battery Management → Auto Start

Turn off auto-start for all applications except:

• 📞 Telephone and SMS.
• ⚡ System Services (Google Play Services, MIUI System).
• 🔔 Messengers (if you need notifications).

Limiting activity in multitasking

By default. MIUI It stores all newly opened applications in memory to limit their number:

Settings → Home screen → Recent → Limit of recent tasks (set 3-4)

This will reduce the load on RAM, but the most important applications will not be closed.

If you’re actively using Google Chrome, switch to Bromite or Firefox Focus – they block ads and heavy scripts, speeding up page loading on weak devices.

💡

Lightweight versions of applications (Lite) not only save memory, but also spend on the use of the 30-40% battery-less.

5 Hardware tricks: Accelerating iron without risk

Redmi 6A It is based on the MediaTek Helio processor. A22, It has hidden performance reserves, and you can activate them without rooting or flashing them using standard tools. MIUI.

Initiation of the performance mode

V MIUI There's a hidden mode that prioritizes the speed of energy saving:

Settings → Battery and Performance → Performance Mode → High-performance

adb shell su


echo "10000" > /proc/sys/vm/min_free_kbytes




echo "0" > /proc/sys/kernel/sched_boost

These teams:

• 🔧 Increase the minimum amount of free memory (min_free_kbytes).
• ⚡ Disable unnecessary acceleration of task scheduler (sched_boost).

Effect: The smartphone will become more responsive when opening apps, but may discharge a little faster.

⚠️ Attention: Teams ADB They're going to work until the first reboot, and to make the changes permanent, you're going to need a root or a custom core!

Use of external SD-maps as internal memory

If you have a fast one installed SD-map UHS-I U3 It can be used as an extension of internal memory:

Settings → Memory → SD- Card → Set up as internal memory

This will allow you to install applications directly on the map, but note:

• 🔄 The card will be encrypted and will not be read on other devices.
• 🐢 Speed of application with SD-cards are lower than internal memory.

6. Alternative firmware: should you switch?

If all of the above methods didn't work, you might want to consider a firmware reflash. 6A There are several alternatives:

For beginners, the best option — MIUI Europa.It retains all the features of standard firmware but removes ads and unnecessary Xiaomi services.Installation takes about 30 minutes and requires no in-depth knowledge.

If you’re willing to sacrifice stability for speed, try LineageOS. 6A It works faster than the standard. MIUI, But there may be a problem with:

• 📸 Camera (no GCam support without modifications).
• 🔋 Battery (the cost increases by the 20-30%).
• 📶 Mobile phone service (in some regions, there may be problems with mobile phone service) 4G).

Before the firmware must:

1. Unlock the bootloader through the official Xiaomi website (it will take 72 hours).
2. Install. TWRP Recovery for Redmi 6A (version 3.5.2 or later).
3. Make a full backup through TWRP (section EFS s IMEI).

⚠️ Warning: Firmware re-flashing voids the warranty and may result in a device blink (inoperability) if the wrong firmware version is selected. 6A Only firmware with the code name cactus is suitable!

Extreme measures: resetting and remarking of memory

If Redmi 6A Even after all the manipulations, there are two radical methods:

Hard Reset (Hard Reset)

This will delete all the data and return the smartphone to the factory settings.

• 📉 The smartphone brakes immediately after switching on.
• 🔄 Apps are constantly flying out with errors.
• 📱 Memory is clogged with unknown files (possible infection with viruses).

Instructions:

Settings → About phone → Reset settings → Delete all data

After reset, do not restore data from the backup – install only the necessary applications manually.

Remarking of internal memory

Over time, the file system f2fs (redmi 6A) It gets fragmented, which slows down the reading/write. TWRP:

1. Boot in. TWRP Recovery (holding power) + Vol+ switch-on).
2. Select Wipe → Advanced Wipe.
3. Select Repair or Change File System → Resize File System.
4. Confirm the action and restart.

This procedure does not delete data, but be sure to back up in case of a crash.

If that doesn’t work, the problem may be in the hardware:

• 🔋 Worn-out battery (at a discharge below 20%, the smartphone begins to brake).
• 🔌 Faulty flash memory (checked through the ADB Adb shell df -h).
• 🔥 Overheating of the processor (clean the charging connector and speaker from dust).

8. Additional tips for gamers
