How to accelerate Xiaomi Redmi 8 in 2026: a complete guide to optimization

Why Redmi 8 is slowing down and how to fix it

Even the budget Xiaomi Redmi 8 with a Snapdragon 439 processor and 3/4 GB of RAM can work quickly — if you set the system correctly. The main causes of brakes: overloaded memory, background processes and outdated firmware. In this article, we will discuss 10 proven ways to speed up a smartphone without root rights and complex manipulations.

It's important to understand that Redmi 8 won't be a flagship, but once optimized, you'll notice the difference in application launch speed, interface smoothness, and battery life. We tested all methods on the current MIUI 14 (Android 11) firmware, the results in the table below.

1. Hand-cleaning cache and debris

System cache and residual application files are the main memory eaters. On Redmi 8 with 64 GB of storage, free space is critical to performance. Start with manual cleaning:

• 📱 Go to Settings. → Memory. → Clean and press "Clean" (removes until) 1-3 GB of garbage)
• 🗑️ In the same menu, select "Deep Clean" - analyzes rarely used files.
• 🔍 For each application: Settings → Annexes → Select an application → Memory. → Clear the cache

Critical user error: Clearing the messenger cache (WhatsApp, Telegram) removes media files from chats!

2. Optimization of application autoloading

By default, MIUI allows most applications to run when the phone is turned on, which increases the boot time by 20-30%.

1. Open Settings → Applications → Permissions → Autorun
2. Sort the list by date of last use
3. Turn off auto-run for apps you use less than 1 time per week

Pay particular attention to:

• 🎮 Games (they consume up to 500 MB of RAM in the background)
• 📊 Analytics Services (Google Play Services, Mi Analytics)
• 🛒 Marketplaces (AliExpress, Wildberries, Ozon)

3. Customization of interface animation

MIUI uses smooth transition animations that are visually beautiful but slow down on weak devices.

1. Activate Developer Mode: Settings → About Phone → MIUI Version (click 7 times)
2. Back to Settings → Additionally. → For developers
3. Find the items: Window Animation Scale → Off. or 0.5x Transition Animation Scale → Off. or 0.5x Animator Duration → Off.

⚠️ Caution: Disabling animations will make the interface less smooth visually, but will speed up the system's response to the new system. 15-20%. This method is particularly effective for Redmi. 8 s 3 GB RAM.

4. Update of firmware and system core

Performance is directly dependent on the version of MIUI. Recent updates for Redmi 8 (2023-2026) include optimizations for weak processors.

For update:

1. Go to Settings → About the phone → System update
2. Click "Check Updates"
3. If a new version is available, download (preferably via Wi-Fi) and install it.

5. Transfer applications to a memory card

Redmi 8’s internal memory (eMMC 5.1) is faster than microSD, but when it is 90%+ full, the system starts to slow down. The optimal solution is to transfer heavy applications to an A2 memory card (minimum write speed of 4000 IOPS).

Instructions:

• 📱 Insert microSD (recommended volume) 64-128 GB)
• 🔧 Formatting as internal memory in Settings → Memory. → Memory map
• 🔄 Restart your phone (required!)
• 📦 For each application: Settings → Annexes → Choose. → Memory. → Change. → Memory map

⚠️ Note: Not all applications support portability SD. System programs (Google Play, Settings) and some games (PUBG, Genshin Impact cannot be moved, and the speed of the ported applications will be lower on the Internet. 10-15%.

💡

Before formatting the card as internal memory, back up the data – all files on it will be deleted!

6. Disabling unnecessary functions and services

MIUI is overloaded with background services that are constantly consuming resources.

Further, turn off:

• 📡 Search for devices in Settings → Connections → File transfer
• 🔊 Touch sounds in Settings → Sounds and vibrations
• 🌐 Mobile data for background processes in Settings → SIM-maps and mobile networks → Transfer of data

7. Reset to factory settings (last resort)

If all the previous methods didn't work, do hard reset, which is a radical way to get your phone back to factory speed, but delete all the data.

Resetting instructions:

1. Go to Settings → Additional → Recovery and Reset
2. Select "Settings Reset"
3. Confirm the action (you will need to enter a pattern lock)/PIN)
4. Wait for the reboot (it will take 5-10 minutes)

⚠️ Attention: After the Redmi reset 8 It will work faster, but: All applications will have to re-set network settings (Wi-Fi passwords) will be erased 2-3 The system may slow down due to background optimization

8. Alternative firmware (for advanced)

The official MIUI is not always optimal for weak devices. Alternative firmware like Pixel Experience or LineageOS can give performance gains of up to 30%, but require unlocking the bootloader and installing via fastboot.

The advantages of custom firmware for Redmi 8:

• 🚀 A lighter interface without unnecessary services Xiaomi
• 🔄 Up-to-date versions of Android (up to version 13)
• 🛡️ No built-in advertising and analytics

⚠️ Note: Custom firmware installation: Reset the warranty (if it is still valid) Requires unlocking the bootloader (the process takes up to a maximum of three hours). 72 Can lead to a "brick" in case of errors during firmware Detailed instructions for Redmi 8 (codename olivelite on [forum.xda-developers.com](https://forum.xda-developers.com).

💡

Custom firmware is the most productive, but it requires technical skills, and for most users, a formal MIUI with the right settings is enough.
