Why Xiaomi is taking a long time to reboot and how to fix it?

You've turned on a Xiaomi smartphone, and instead of a desktop, you see an endless download with the Mi logo? The device "thinks" 5, 10, or even 30 minutes before finally booting up - or even hangs in the middle of the process? This problem is familiar to many owners of Redmi, POCO and Mi phones, especially after system updates or failed experiments with settings.

A long reboot isn't always a critical failure, and 80 percent of the time it's caused by software failures that can be fixed without going to the service center, but it's important to understand that if a smartphone has been stuck on the logo for more than 20 minutes and doesn't respond to buttons, the next steps depend on the cause, and in this article, we'll look at all the possible scenarios, from basic methods like clearing the cache to radical measures like flashing through Fastboot.

Before you start repairing, answer two questions: 1. When did the problem first appear? After updating, installing an app, or physical damage (hitting, getting moisture)? 2. Does the smartphone at least occasionally boot to the desktop, or hangs on the Xiaomi logo all the time?

The choice of the recovery method depends on the answers.

1.The reasons for Xiaomi's long reboot

Xiaomi smartphones based on MIUI (or HyperOS in new models) can slow down when booting for several reasons.

• 🔄 Failure after software updates: Incorrectly installed updates (especially over the air) often lead to conflicts of system files. MIUI 13 on MIUI 14 or HyperOS can "break" the bootloader.
• 🗑️ Cache overflow, system partition /cache It is clogged with temporary files, and the smartphone spends minutes processing them every time it is turned on.
• 📱 Application conflict. Viruses, pirates. APK or programs with root rights can block critical boot processes (e.g., zygote or surfaceflinger).
• 🔋 Battery problems: If the battery swells or the charge controller fails, the smartphone may “think” it was turned off during the upgrade and try to recover.
• 🛠️ Hardware malfunctions. Damaged flash memory (eMMC or UFS), A broken plume or burnt-out power chip leads to a cyclical reboot.

EMMC models (such as Redmi 4X, Redmi Note 5 or POCO F1) are particularly vulnerable, and these chips wear out after 3-5 years of active use, and the smartphone starts to “glut” when reading system files, in which case software methods help temporarily, and the final solution is to replace memory.

⚠️ Warning: If a Xiaomi smartphone reboots after falling or getting moisture, DO NOT try to sew it yourself! this can aggravate the damage to the board.

2. Quick ways to speed up loading (without resetting)

If your smartphone still loads but takes too long (5-15 minutes), try these methods without losing data.

2.1 Clearing the cache through Recovery

The safest way is to reset /cache and /dalvik-cache partition cache, which will not delete your files, but will remove temporary data that can slow down loading.

1. Turn off your smartphone (clip Power + Volume up for 10 seconds).
2. Press Power + Volume Up to Enter Recovery Mode.
3. Select a language (if required), then go to Wipe & Reset → Wipe Cache.
4. Confirm and restart (Reboot → Reboot to System)

If the smartphone booted faster after this procedure, the problem was clogged. Repeat cleaning every 2-3 months for prevention.

Disable autoloading of applications

Some programs (especially Chinese launchers or optimizers) start when the system is booted and slow down the process.

1. Go to Settings → Applications → Autoboot.
2. Sort the list by the date of the last launch.
3. Turn off autoboot for unnecessary apps (e.g. Mi Video, Mi Browser, Clean Master).

💡

If you can’t find the “Outload” option, turn on “Show System Processes” in the application settings.

Checking of the battery

If the smartphone is thinking on the logo for a long time, but then it loads, the problem may be in the battery.

• 🔌 Connect the charger and observe the behavior. If the loading speeds up, it's the power controller's fault.
• 📉 Install the AccuBattery app and check for Battery Health. If it's below 80%, it's time to change the battery.

3. Radical methods: resetting and flashing

If the smartphone is stuck on the logo all the time and doesn’t load even after cleaning the cache, you’ll have to use more serious measures. Importantly, these methods will delete all data (photos, contacts, messages), so try to extract information through ADB (if the smartphone reacts to the connection to the PC in any way).

3.1 Hard Reset (Hard Reset)

This is a complete cleanup of user data and a return to factory settings, suitable if the problem is caused by viruses or application conflicts.

1. Enter Recovery Mode (Power + Volume Up buttons).
2. Select Wipe Data → Wipe All Data (or Factory Reset)
3. Confirm the action and wait until it is completed (may take 5-10 minutes).
4. Reboot to System (Reboot to System)

If after resetting the smartphone still loads for a long time, the problem lies deeper - perhaps damaged firmware or hardware.

3.2 Flashing through Fastboot

This is the last method used if:

• 📱 The smartphone does not load even in Recovery.
• 🔄 After the reset, there is an error No. OS installed or Bootloop.
• 🛠️ You suspect system files being damaged (for example, after a failed rooting).

You'll need firmware.

• A computer with Xiaomi drivers installed and the Mi Flash Tool program.
• Original firmware for your model (download from the official website en.miui.com).
• USB Type-C cable (preferably original)

Instructions:

1. Unpack the firmware in a folder without Cyrillic characters (for example, C:\MIUI\).
2. Turn off your smartphone and press Power + Volume down to log into Fastboot.
3. Connect your phone to your PC and start the Mi Flash Tool.
4. Select the firmware folder, press Refresh, then Flash.
5. Wait for the finish (10-15 minutes) and restart the device.

⚠️ Note: Fastboot erases all data, including the contents of internal storage. If your smartphone had important files, try extracting them first. ADB pull (if the device is determined by PC).

4. Hardware malfunctions: when to carry in the service

If none of the software methods worked, the problem is probably hardware, and here are the signs that the smartphone should be shown to the wizard:

It's especially dangerous to ignore memory problems (eMMCs), because if a smartphone writes errors like EMMCDL Mode or Boot Certification Verify, it means that the memory chip is starting to crumble, and in such cases, even flashing it back will help temporarily, in a week or two, the only solution is to replace the memory, but in most Xiaomi models it is soldered into a fee, so it will cost 50-70% of the cost of the new phone.

💡

If Xiaomi is older than 4 years and has started to “glutch” when booting, it is likely to blame worn-out memory (eMMC).

5. How to prevent long loads in the future

To Xiaomi smartphone does not slow down when turning on, follow these rules:

• 🔄 Update on time, but not through OTA, It's manual (download the full firmware package from the official website) and it reduces the risk of failure.
• 🗑️ Clean the cache every 2-3 months through Recovery or apps like this. SD Maid.
• 📱 Don't install pirates. APK Don’t give root to dubious programs.
• 🔋 Keep an eye on the battery: do not discharge below 10% and do not leave on overnight charging (use a charge limit of up to 80% in the settings).
• 🛡️ Turn off automatic optimization in Settings → Special facilities → Optimization MIUI (It often conflicts with the background processes).

If you like firmware experiments, install only proven custom ROMs (like Pixel Experience or LineageOS) and always back up TWRP before you change. Remember, 90% of bricks (default phones) are due to incorrect firmware or interrupted upgrades.

6.Frequent errors in Xiaomi recovery

Many users make the problem worse with the wrong actions, and here's what you can't do if your smartphone is rebooted for a long time:

• ❌ Interrupting the firmware (pulling the cable or turning off the PC) can kill the bootloader).
• ❌ Install firmware from another model (for example, flash Redmi Note 10 files from Redmi Note 10 Pro) This is guaranteed to turn the phone into a “brick».
• ❌ Use informal tools like SP Flash Tool for MediaTek devices without backup. IMEI.
• ❌ Charge your smartphone with left-handed charges during recovery.Potency surges could damage the board.

If you are not sure of your actions, you should contact the service. For example, restoring IMEI after a failed firmware will cost 1–2 thousand rubles, and independent attempts can make the phone unfit for repair.
