Why Xiaomi Redmi is slowing down: all the reasons and working ways to accelerate

Introduction: Why even the new Redmis are starting to "lay down"

You picked up your Xiaomi Redmi and again faced with annoying hangovers: apps open through the 5-10 And in the second, the animations twitch, and sometimes the screen freezes for a few moments, and even if you bought your smartphone less than a year ago, it doesn't guarantee smooth operation. It's not always about hardware, because software crutches that accumulate over time are often to blame.

Redmi performance (be it Note 12 Pro)+, Redmi 10C Or even a flagship model like this. K60 Ultra) depends on three key factors: RAM, storage and optimization. MIUI. At the same time, even 12 GB of RAM will not be saved if the system is clogged with garbage, and the background processes eat up 80% of resources. In this article, we will analyze the unique reasons for Xiaomi brakes - from hidden functions. MIUI Up to the hardware features of the Snapdragon and Mediatek processors.

Important: If your Redmi is only slowing down in games (like Genshin Impact or Call of Duty Mobile), the problem is more graphical settings or overheating.

1. Overloaded RAM: Why Redmi is "suffocating" from background processes

MIUI It aggressively caches applications so they open faster when they are re-started, but this mechanism often works against the user: instead of freeing up RAM, the system stores dozens of unnecessary processes in memory:

• 📱 Social networks (Facebook, TikTok, Instagram) – even after closing, they continue to sync data.
• 🎵 Music services (Spotify, Yandex Music) – take up to 300 MB of RAM each.
• 📊 System services MIUI (For example, com.miui.analytics or com.xiaomi.midrop – they can not be disabled without root rights.

To check the current load on RAM:

1. Open the settings → About the phone → Memory.
2. See the RAM usage schedule in the Memory Use section.
3. If less than 1 GB is free, it’s time to clean.

⚠️ Warning: Don't believe the myth that "free RAM is bad." 6-8 The GB RAM should be free at least 1.5-2 GB for comfort, and if it's smaller, it starts to drop things onto the disk, which causes the brakes.

2.Clogged storage: how 90% of the filled memory kills speed

MIUI It starts to slow down when the internal memory is 85% or more full. F2FS, This system is optimized for speed, but when space is scarce, it has to fragment data, which leads to a loss of space:

• 🐢 Slowing down the launch of applications (especially heavy ones – WhatsApp, Telegram, games).
• 🔄 Hanging up when recording videos or taking photos.
• 📉 The decline in productivity 30-40% (by the AnTuTu test).

Check the storage capacity:

1. Go to Settings. → Warehouse.
2. Please note the System Data section if it is more 15-20 GB, time to clean the cache.

Excessive photos and videos (especially in the DCIM/.thumbnails)

Application cache (Settings) → Annexes → Select an application → Warehouse → Clear the cache)

Unused. APK-files (download folder)

Duplicate files (use Files by Google or MIUI Cleaner)

-->

3. Hidden functions MIUI, plunderer

Xiaomi has dozens of features embedded in the firmware that run in the background and eat up performance, many of which cannot be disabled through standard settings, but can be blocked through the use of a computer. ADB Applications such as App Inspector.

Top.-5 most voracious services MIUI:

1. com.miui.analytics – collects data about phone usage (you can disable the Settings) → Confidentiality → Analytics).
2. com.xiaomi.midrop is a wireless file transfer service (works even when not in use).
3. com.miui.cloudservice – synchronize with Mi Cloud (constantly checks for updates).
4. com.miui.hybrid – responsible for “smart” tips and recommendations (slows down the interface).
5. com.android.updater – checks firmware updates every 2 hours.

To disable unnecessary services without root rights:

1. Activate Developer Mode (7 times click on the MIUI version in Settings → About Phone).
2. Enable USB Debugging in Developer Settings.
3. Connect your phone to your PC and execute the command: adb shell pm disable-user --user 0 com.miui.analytics (replace com.miui.analytics with the name of the service you don’t need).

⚠️ Warning: Disabling system services may cause some functions to fail MIUI (For example, dark theme or navigation gestures. Before making changes, back up through Settings. → Additionally. → Backup and reset.

4.CPU overheating: why Redmi 'strangles' performance when heated

All Xiaomi Redmi smartphones (especially on Snapdragon processors) 7xx And Mediatek Helio G, too, suffer from thermal throttling, which is a forced processor frequency reduction when it overheats, which protects the phone from damage, but causes it to drop dramatically. FPS interface-game.

Normal temperatures for Redmi:

• 🟢 40.°C is the optimal mode.
• 🟡 40-45°C – light throttling begins (productivity falls on the 10-15%).
• 🔴 45-50°C - severe throttling (falling to the 30-50%).
• 🚨 Above 50.°C - Emergency shutdown (the phone may be turned off).

To check the temperature:

1. Install the AIDA64 or CPU Monitor app.
2. Run a load test (for example, a game) PUBG Mobile at maximum settings).
3. Keep an eye on the processor temperature chart.

If the phone overheats:

• 🛠️ Remove the case – even a thin silicone case can raise the temperature on the 3-5°C.
• 🔄 Close the background apps (especially Google Maps, Camera, Games).
• 📉 Reduce the screen resolution to HD+ (In Settings → Display. → Screen resolution).
• 🔋 Do not charge your phone during games – it increases the heat.

💡

If the game starts to slow down through 10-15 For a minute, try to turn on the Game Turbo mode in Settings → Special facilities → It optimizes resource allocation, but it can slightly reduce the graphics for stability. FPS.

5. Brakes in games: why Redmi "doesn't pull even mid-range settings"

Many Redmi owners face a paradox: the phone has a powerful processor (for example, the Snapdragon 870 in Redmi). K40), But in games, it's low. FPS Or slowing down:

• 🎮 Graphics Drivers – Xiaomi often uses outdated versions of Adreno drivers (for Snapdragon) or Mali (for Mediatek).
• 🔧 Limitations MIUI — Firmware artificially lowers performance in games to reduce heat.
• 📡 Poor Internet connection – in online games (Free Fire, Call of Duty) lagas can be due to high ping, not hardware».

How to remove the brakes in games:

1. Update graphics drivers: For Snapdragon: install the latest version of Adreno Drivers from Qualcomm. For Mediatek: use Mali utility GPU Driver Updater.
2. Turn off the restrictions MIUI: Enable Developer Mode. Activate the option to Disable Background Restriction (PUBG, Genshin Impact: Choose High Performance over Balanced.

Check the ping.

• Run the speed test in Speedtest.
• If ping is above 100ms, connect to another Wi-Fi network or use mobile internet.

💡

Redmi with Mediatek Helio processors G95/G96 (For example, Redmi Note 11 Pro) brakes in games are often associated with poor memory VRAM. Try to reduce the textures to the average – it will give an increase FPS drawdownless.

6.Outdated firmware or beta version MIUI

Xiaomi regularly releases updates for its smartphones, but not all are stable.Beta MIUI They often contain bugs that cause:

• 🐌 Slowing down interface animation.
• 🔄 Self-involved reboots.
• 📱 Freezes when the screen is unlocked.

How to check the relevance of the firmware:

1. Open Settings → About the phone → System update.
2. Compare the version. MIUI The latest stable on the Xiaomi Firmware website.
