How to bring Xiaomi device out of deep sleep: from smartphone to smartwatch

You turned on a Xiaomi smartphone, but the screen is black, the indicators are not lit, and pressing buttons do not give any reaction? Perhaps the device has gone into a deep sleep — a power saving mode in which the system turns off all non-critical processes, including the interface. In 90% of cases, this is not a hardware failure, but a software failure that can be fixed by yourself.

Deep sleep is a regular MIUI and HyperOS mechanism designed to save battery power. However, sometimes the device falls asleep too deeply: does not respond to charging, does not vibrate when holding the power button, and connecting to the PC does not cause any sound signals. In this article, we will discuss 5 proven ways to bring Xiaomi out of deep sleep – from simple manipulation of buttons to forced flashing through Fastboot.

Importantly, the methods are different for smartphones, Mi TVs and wearables (bracelets, watches), and we will look at each type of equipment separately so that you do not waste time on inefficient actions.

Why Xiaomi is not waking up: Why Xiaomi is not waking up

Deep sleep isn’t always a mistake, for example, Xiaomi smartphones with Ultra Battery Saver can go into this mode at a discharge below 5% to save energy for emergency calls.

• 🔋 Critical battery discharge (even if the indicator showed 10-20%, the controller could turn off power due to a malfunction of the battery).
• 🤖 Firmware failure after update MIUI/HyperOS orthose.
• 🔌 Charger problems: A substandard cable or power supply does not provide enough current to "wake up».
• 🛠️ Hardware malfunctions: oxidation of battery contacts, damage to the power button plume.
• 📱 Application conflict: Some programs (such as Greenify or Battery Guru) aggressively optimize background processes.

Mi Band and Mi Watch devices often experience deep sleep due to a discharge of up to 0% or a sync failure with the Mi Fitness app. Mi TVs can "fall asleep" after a firmware update if it has been interrupted.

⚠️ Note: If you rotated your device or installed custom software before you “fall asleep”, forced awakening can lead to data loss or “brick” (complete inoperability). ADB.

Method 1: Forced Reset (Hard Reset)

The easiest and safest method is hardware reset, which works on 80% of Xiaomi devices unless the problem is a physical breakdown.

• 📱 Smartphones with removable battery (for example, Redmi) 4A, Redmi 5A): Remove the battery for 30 seconds, then insert back and turn it on.
• 📱 Smartphones with non-removable battery (Redmi Note 10, POCO X3, Mi 11: Press the power button + Volume up 10-15 seconds until the Mi logo appears.
• ⌚ Smart Watches/Bracelets (Mi Band 7, Mi Watch): Connect to charge and hold the physical button (if any) for 20 seconds.
• 📺 Mi TVs TV: Press and hold the Power button on the remote for 10 seconds, then disconnect from the network for 1 minute.

If the device is switched on after reset, but goes to sleep again, check the energy saving settings. In MIUI, go to Settings → Battery → Energy Saving Mode and turn off the Ultra-Economic Mode option.

Make sure the device is charged (minimum 5%)

Disconnect from PC/charging (if connected)

Use the original Xiaomi cable

Try another charger (with Quick Charge support)

-->

Method 2: Charging in “recovery mode”

If the smartphone does not respond to the buttons, but when you connect to the charge, the battery indicator appears (even for a fraction of a second), the problem may be insufficient voltage.

1. Connect the device to the original charger (or with Quick Charge 3.0+ support).
2. Leave on charging for at least 30 minutes, even if the indicator is not lit.
3. Try to turn on by holding Power + Volume down (this can download Fastboot).
4. If the screen is black but the device is getting warmer, try to turn on every 10 minutes.

For the Mi Band and Mi Watch, use the magnetic cable from the kit.

• 🔌 Connect to the other one. USB-port (better on the back of the PC).
• 🔋 Try charging from a power bank (sometimes helps).
• ⚡ Leave on charging 1-2 hours - sometimes the indicator appears only after a minimum charge is set.

💡

If the charging indicator flashes red and goes out, this is a sign of a battery failure. Try connecting the device to your PC and check if it is detected in the Device Manager (Portable Devices section).

Method 3: Connect to PC and ADB commands

If a device is identified by a computer (even as “unidentified”) but does not turn on, you can try “waking” it through ADB (Android Debug Bridge), a method suitable for Xiaomi smartphones and tablets with an unlocked bootloader.

Step-by-step:

1. Download and install Platform Tools (includes adb and fastboot).
2. Connect the device to the PC via USB.
3. Press Power + Volume down for 10 seconds to go to Fastboot.
4. Open the command line in the folder with Platform Tools and type:

fastboot devices

If the device is determined (the serial number appears), do:

fastboot oem edl

This command will put the smartphone in EDL (Emergency Download Mode) mode, after which it can be flashed through the Mi Flash Tool.

⚠️ Note: The fastboot oem edl team doesn't work on all Xiaomi models. on new devices (e.g. Redmi Note 12, POCO F5) You may need an authorized account to unlock.

Method 4: Firmware via Mi Flash Tool (for smartphones)

If the device is still in deep sleep, even after ADB, you have to manually reflash it, which is a last resort, but it works 95% of the time.

• 🖥️ Windows PC 7/10/11.
• 🔌 Original. USB-cable.
• 📥 Firmware for your model (download from the official Xiaomi website).
• 🛠️ Mi Flash Tool Programming.

Instructions:

1. Unpack the firmware (file with.tgz extension) in a folder without Cyrillic characters.
2. Install the Mi Flash Tool and drivers (if the PC doesn’t see the device in Fastboot).
3. Put your smartphone in EDL mode (see method 3) or use testpoint (for new models).
4. In the Mi Flash Tool, select the firmware folder, press Refresh, then Flash.
5. Wait until it's finished (10-15 minutes) and the device will automatically restart.

Once you have the firmware, the device will be in factory condition, all data will be deleted, and if you have Mi Account enabled, you will need to enter your username and password to unlock it.

Method 5: Specific methods for Mi TVs and wearables

Mi TVs and Xiaomi smartwatches/bracelets have their own wake-up nuances. Let's take a look at them separately.

For Mi TVs (all models)

• 🔌 Turn off the TV for 5 minutes, then turn it on.
• 🎮 On the remote, pinch the Menu. + Volume down for 10 seconds (reset settings).
• 📡 If the TV does not respond to the remote, connect the keyboard or mouse on the USB — Sometimes it wakes up the system.
• 🔄 To reset the firmware, download the update file to the flash drive, paste it into the port. USB Hold the power button for 15 seconds.

For smart watches and bracelets (Mi Band, Mi Watch)

• ⌚ Connect to charging and hold the button for 30 seconds (for the Mi Watch – touch area).
• 📱 In the Mi Fitness app, remove the device and re-sync.
• 🔄 For the Mi Band. 5/6/7: Connect to charging, then quickly tap the sensor 10 successively.
• 🔋 If the bracelet is not charged, check the contacts for oxidation (wipe with alcohol).

💡

Xiaomi smartwatches often fall asleep after updating the firmware. If the bracelet does not respond to charging, try connecting it to another power source (for example, to a power bank) - sometimes the problem is insufficient current from the battery. USB-port.

What do you do if nothing helps?

If all methods have been tried, but the device remains in deep sleep, hardware malfunctions are possible:

• 🔋 Failure of the battery (blown, loss of capacity).
• 🛠️ Damage to the motherboard (often after falling or getting moisture).
• 🔌 Oxidation of contacts (especially relevant for Mi Band after sweating).
• 📱 Failure of the power controller (requires soldering or replacement of the chip).

In these cases, self-repair is not recommended - contact the Xiaomi service center or workshop with diagnostic equipment.

⚠️ Note: If the device was purchased less than a year ago, repairs may be free of charge under warranty.
