Xiaomi Mi5, released 2016 The year, still remains a cult smartphone among enthusiasts thanks to the top at that time “iron”: the Snapdragon processor. 820, 3/4 GB of RAM and AMOLED-But with the release of modern apps and Android updates, even the flagships of the past are beginning to slow down. Mi5 You're slow to react to touch, you open apps for a long time, or you overheat when you're under load -- that's not a sentence. 7 proven ways to return the device to its former speed, from basic software optimizations to radical hardware modifications.
It's important to understand that the speed of a smartphone depends on three key factors: software status (firmware, background processes), hardware constraints (battery wear, chipset overheating), and user habits (number of installed applications, cache cleaning frequency). We structured acceleration methods by complexity, from the simplest to the most demanding technical skills. Start with the first section and move consistently: maybe radical measures will not be necessary.
1. Cleaning up the system: removing digital garbage
The first step to speed up is to free up memory and delete unnecessary data. Mi5 App cache, residual files of deleted programs and duplicate media files accumulate. Even 32 GB of internal memory (in the basic version) can be clogged to failure if you do not monitor the order.
Start with the built-in MIUI tools:
- 🧹 Cache Clearing: Go to Settings → Warehouse → Clean up and click "Clean up." Pay special attention to the "App Cache" and "Download" sections, where gigabytes of unnecessary data often accumulate.
- 🗑️ Removing duplicates: Use Files (from Google) or Files by Xiaomi to find and delete repetitive photos, videos and documents. on average, this frees up 2–5 GB of space.
- 📦 Bloatware uninstallation: many system applications MIUI (For example, Mi Music, Mi Video) can be turned off without root permission. → Annexes → Manage applications, select the unnecessary and click "Disable».
If built-in tools are not enough, install third-party utilities:
- 🛠️ SD Maid – Deep System Garbage Cleanup (requires root for full functionality).
- 🔍 CCleaner - Delete cache and temporary files (free version limited).
- 📊 Storage Analyzer – visualization of occupied space by category.
⚠️ Please do not use “optimizers” like Clean Master or DU Speed Boosters – They often contain ads, collect data and can impair performance due to background activity.
2. Firmware optimization: from updates to custom ROM
Standard firmware MIUI Xiaomi Mi5 And it becomes the main source of lag over time:
- 🐢 Older version of Android: official support Mi5 ended on Android 8.0 Oreo, but custom firmware allows you to install Android 11 or even 12.
- 📱 Pile-up MIUI: Xiaomi shell is known for redundant animations and background processes.
- 🔄 Unstable Updates: Some Versions MIUI for Mi5 contain bugs that cause hanging.
Options for a solution:
Updating to the latest official firmware
Check the relevance of the software:
- Go to Settings → About the phone → System update.
- If a new version is available, download it and install it. Mi5 last-stable MIUI — V12.5.3.0 (Android 8.0).
- After the update, reset settings (Settings → Additional → Restore and Reset).
B. Installation of custom firmware
For experienced users, the best way to speed up Mi5 — slip-over:
- 🚀 LineageOS 18.1 (Android 11) is fast and stable.
- ⚡ Pixel Experience – pure Android with Google optimizations.
- 🔥 Havoc-OS – Customizable firmware with the core for improved performance.
The installation will require:
- Unlock the bootloader (fastboot oem unlock).
- Install TWRP Recovery (version 3.6.2 for the Mi5).
- Switch firmware and GApps (if you need Google services).
⚠️ Warning: Inept firmware can turn a smartphone into a brick.Before you start, check the firmware compatibility with the model Mi5 (codename gemini and make a backup through TWRP.
How to check the model Mi5 before-fixing?
4 Hardware modifications: when software does not help
If software methods have failed, the problem may lie in the physical wear and tear of components. Mi5 Two “diseases” affecting productivity:
- Thermopaste degradation – over time it dries up, leading to overheating and trottling (automatically reducing the processor frequency).
- Battery wear – Capacity drops below 70% and the smartphone starts to limit performance to save energy.
Solutions for hardware upgrade:
A. Replacement of thermopaste
The procedure requires disassembly of the device, but gives a noticeable increase in stability:
- Buy a high-quality thermal paste (such as Arctic) MX-6 Or the Thermal Grizzly Kryonaut).
- Take it apart. Mi5, following the iFixit guide (Difficulty level: average).
- Remove the old paste from the processor and memory chips with alcohol, apply the new thin layer.
The result: a 10-15 decrease in temperature°C under load and lack of trottling.
B. Battery replacement
Original battery Mi5 (3000 mAh) after 3-4 years of operation loses up to 30-40% of capacity. ZMI) It will restore autonomy and remove productivity constraints.
- ⚠️ Buy a battery only with the original controller – cheap analogues can swell.
- 🔧 Replacement will require a hair dryer (to peel off the back cover) and plastic shoulder blades.
Installation of the cooling radiator
For gamers, a thin copper or graphite radiator (such as the Cooler Master Mobile Cooling Pad) is glued to the back cover in the processor area. Reduces the temperature by 5-8°C for long periods of load.
| Modifications | Difficulty | The effect | Cost (rupe) |
|---|---|---|---|
| Replacement of thermopaste | Medium | −10–15°C, no trottling. | 300–800 |
| Battery replacement | Tall. | +30-50% autonomy, no CPU limitations | 1 200–2 000 |
| Installation of radiator | Low. | −5–8°C in games | 200–500 |
| Dust cleansing | Low. | −3–5°C, better heat dissipation | 0 (independently) |
💡
Before the disassembly Mi5 warm the back cover with a hair dryer at 60-70°C for 2-3 minutes - the glue will become softer, and the risk of damage to the plumes will decrease.
5. Overclocking and undervolting: playing with frequencies
For users with root rights and custom core, advanced processor settings are available. Snapdragon 820 in Mi5 It has hidden potential: with the right setup, you can get +15-20% performance without critical temperature rise.
Tools for dispersal:
- 🔧 Kernel Adiutor – Frequency Control CPU/GPU, governor and voltage.
- ⚡ FrancoKernel Manager – Optimizing the kernel for balance of performance and autonomy.
- 📊 CPU Tuner – Automatic profile management depending on the load.
Safe settings for the Snapdragon 820:
- Undervoltage: Reduce voltage by 25-50 mV for each frequency (test for stability!).
⚠️ Warning: Overclocking shortens the life of the chipset and can lead to overheating.Always test stability in the chipset Prime95 or 3DMark When you see artifacts or reboots, return the standard settings.
💡
Undervoltage reduction often gives you a greater performance boost than overclocking, because it reduces trottling from overheating. Start with that!
6.Alternative launchers and lightweight applications
MIUI Launcher – one of the main “brakes” in Xiaomi Mi5. Its animations, widgets and background processes eat up to 15-20% of RAM. Replacing it with a lightweight launcher can speed navigation by 30-40%.
Top.-3 launcher Mi5:
- 🚀 Nova Launcher is customizable, process-free. Turn off animations in the settings for maximum speed.
- ⚡ Lawnchair 2 – Pixel-style launcher with minimalist design.
- 🛡️ Smart Launcher 5 – Automatic Application Sorting and Low RAM Consumption.
Also replace the “heavy” applications with lightweight analogues:
| Annex | The alternative | Savings in RAM (MB) |
|---|---|---|
| Chrome | Bromite or Firefox Lite | 100–150 |
| Hermit Lite or web version | 80–120 | |
| Barinstagram (unofficial client) | 60–90 | |
| Google Maps | OsmAnd~ (offline) | 70–100 |
In addition:
- 🎨 Use dark themes — AMOLED-screen Mi5 Spending less energy on displaying black.
- 🔕 Turn off live wallpaper and screen lock animations.
- 📵 Install Greenify for Forced Hibernation of Background Apps.
7 Extreme measures: what to do if nothing helps
If all of these methods fail, there are radical solutions that take time, skills or financial investment, but can bring back the benefits. Mi5 life.
Option 1: Complete reset and flashing
Sometimes the system is so cluttered that the only way out is a clean firmware installation:
- Make a data backup through TWRP Mi Mover.
- Download the latest version MIUI or custom firmware for gemini.
- In TWRP, run Wipe → Advanced Wipe (mark Dalvik, Cache, System, Data).
- Sweep through the firmware and GApps (if necessary).
Option 2: Hardware upgrade
- 🔧 Motherboard replacement: AliExpress sells boards with Snapdragon 821 (from Mi5s), corpus Mi5. Productivity gains: ~25%.
- 💾 Installing eMMC 5.1: Replacing the internal memory with a faster one (such as from Samsung) will speed up reading / writing data.
Option 3: Use as a secondary device
If Mi5 They can’t handle everyday tasks, repurpose them:
- 🎮 Game console: install emulators (RetroArch, Dolphin) and connect the gamepad via Bluetooth.
- 📷 Camera: camera Mi5 (16 MPP, f/2.0) It is still competitive for macro photography.
- 🏠 Smart home: make it a control panel for Xiaomi Home or media server (Kodi).
