How to turn on Xiaomi smartphone if it is completely discharged: 5 working ways

Did you get your Xiaomi out of the drawer after a long downtime and it doesn't show signs of life? Or did your smartphone suddenly turn off because of a critically low charge and now doesn't respond to the power button? The situation is familiar to many owners of Redmi, POCO or Mi devices. Full battery drain is one of the most common reasons why the phone refuses to turn on, but in 90% of cases the problem is solved without visiting a service center.

In this article, we’ll look at all possible scenarios, from basic charging to forced launch via the recovery menu. You’ll learn why Xiaomi may not respond to charging even after connecting to the network, how to distinguish a discharged battery from a hardware breakdown, and what to do if the phone is stuck on the MIUI logo. The instructions are relevant for all models, including the Redmi Note 12, POCO X5, Mi 11 and older devices based on Qualcomm or Mediatek.

We warn you that not all methods are equally safe. For example, forced running through a combination of buttons can lead to a firmware failure if the battery is discharged to 0%. So we will start with the most gentle ways and gradually move to radical measures. If your Xiaomi does not turn on after a drop or moisture is another story, and such cases require diagnostics in the service.

Why Xiaomi doesn’t turn on after the discharge: 3 main reasons

Battery drainage is not always the user's fault, and sometimes hardware or software failures are the problem, and here are three common scenarios that could cause Xiaomi to die and stop responding to charging:

• 🔋 Deep battery discharge: Lithium-ion batteries in Xiaomi smartphones are sensitive to full discharge. 2-3%, The battery controller blocks the battery to avoid damage, and then standard charging might not work, like a push through a high-current charger or a special cable.
• 🔌 Problems with charging port or cable. Contact oxidation, damage USB-The use of a port or a non-original cable can cause the phone to fail to recognize the connection to the network. POCO M3 They often suffer from a broken-up jack. USB-C, who loses contact with time.
• 🤖 Failure of firmware or power controller if the phone is turned off on the update MIUI Or after installing custom firmware, it can "hang" in a low-charge state, in which case forced reset or flashing through the Fastboot is required.

Interesting fact: Xiaomi models on Qualcomm Snapdragon processors (such as the POCO F3 or Redmi K40) have built-in deep-discharge protection – Qualcomm Battery Saver. It automatically turns off the device at a critical charge level, but sometimes it works too aggressively, which makes the phone not turn on even after connecting to charging.

⚠️ If your Xiaomi doesn’t respond to charging for more than a day, and the battery indicator doesn’t light up even when connected to another cable, don’t try to disassemble the device yourself. In 30% of such cases, the bloated battery is to blame, which can damage the motherboard if improperly removed.

Method 1: Standard Charging – The Right Sequence of Actions

Start with the simplest: plug your phone into the original charger and leave it for 30-60 minutes. But even here, there are nuances that many miss out on: Not all power supplies are equally effective at reanimating a run-down Xiaomi, for example.

Here is a step-by-step algorithm that increases the chances of success:

1. Use the original cable and power supply. Xiaomi chargers (especially those with Quick Charge 3.0/4.0 support) deliver a more stable current than cheap ones. Redmi Note 10 and newer models will suit the 33W unit, for old ones (Redmi 8, Mi A2) - 18W.
2. Connect to the socket, not to the socket. USB-PC port: The ports of a computer or laptop often limit the current to 0.5A, What is not enough to start a deeply discharged battery.
3. Leave the phone on charge for at least 1 hour. Even if the screen is not responding, the charge indicator (if any) should light up in 10-15 minutes. In the POCO X3 and Redmi Note 9 Pro models, the indicator is located on the bottom panel.
4. Try another charger. If there's no reaction after an hour, test different power supplies. For example, charging from an iPad (12W) or MacBook (29W) sometimes wakes up stubborn Xiaomi.

Critical: If the phone doesn't show any signs of charging (no indicator, no body heat), but you're sure the cable and power supply are working, the problem could be the power controller on the motherboard, in which case only the service center will help.

Method 2: Forced launch through a button combination

If standard charging didn't work, try hardware reset. This method works even if the battery is discharged to 0%, but requires precise consistency. Wrong actions can lead to a reset or data corruption!

Instructions for most Xiaomi models (including Redmi, POCO, Mi):

1. Connect the phone to the charger.
2. Press and hold the Power + Volume button for 10-15 seconds.
3. If you see a MIUI logo or a Recovery menu, release the buttons. The phone should start downloading.
4. If the screen is black, try again, holding the buttons for 20-30 seconds.

For some models, the combinations are different:

If the phone turned on after a forced start, but immediately turned off, this is a sign of a malfunction of the battery, in which case a replacement of the battery is required, since it does not hold charge even after "resuscitation".

⚠️ Attention, some models (POCO F1, Mi 8) Long-term button retention can cause a factory reset. If you see a menu with items in English (Wipe data, Reboot) - DO NOT choose Wipe, otherwise you will lose all data!

Method 3: Charging via another source (Power Bank, PC, wireless charging)

If the outlet and original charger don't help, try alternative power sources. Sometimes Xiaomi only wakes up after connecting to a power bank or via wireless charging (if the model supports Qi).

Here are the options worth testing:

• 🔋 Power Bank with Quick Charge support. some external batteries (e.g. Xiaomi Mi Power Bank) 3) They're going to give you a more stable current than the outlet. 2-3 hour.
• 💻 USB-laptop-port USB 3.0. Ports of blue (USB 3.0/3.1) They provide more current than standard USB 2.0. Try to connect Xiaomi to such a port on the Internet. 30-40 minute.
• 📶 Wireless charging (for supported models) If your Xiaomi is Qi compatible (Mi) 9, Mi 10, Mi 11 And newer, put it on the charging station and wait. 1-2 Sometimes wireless charging "bypasses" the problems with the USB-port.
• 🔌 Other cable (preferably) USB-C → USB-C). Cables. USB-A → USB-C They often have less bandwidth. Use a symmetrical cable. USB-C → USB-C maximum-current.

Advice from a Xiaomi engineer: if the phone gets a little warmer when you plug in to charge (but doesn't turn on), that's a good sign. So the power controller gets power and the battery is gradually charged, in which case leave the device on charge for 3-4 hours, even if the indicator is not on.

💡

If you have a second Xiaomi smartphone, try connecting the discharged device to it through the phone. OTG-cable (if Reverse Charging is supported (POCO F3, Redmi K40) They can give a charge to another device.

Method 4: Connect to PC and Diagnostics via Mi Flash Tool

If the phone doesn't respond to charging, but the PC can see it, you can try forced firmware through the Mi Flash Tool, which is suitable for devices that are defined by the computer in Fastboot or EDL mode, but do not turn on themselves.

You'll need:

• 💻 Windows computer 7/10/11.
• 🔌 Original. USB-cable (preferably from the set).
• 📥 Mi Flash Tool and firmware for your model (download only from the official Xiaomi website!).
• 🔧 Qualcomm or Mediatek drivers (depending on your phone’s processor).

Step-by-step:

1. Connect the switched off Xiaomi to the PC.
2. Press the Volume Down button + connect the cable to the phone. Hold the button for 5-10 seconds until the PC makes the device connect sound.
3. Open the Device Manager (Win + X → Device Manager) and check if the Qualcomm HS-USB QDLoader 9008 or Mediatek Preloader is available.
4. If the device is determined, run the Mi Flash Tool, select the downloaded firmware and press Flash.
5. Wait until the process is completed (10-15 minutes). The phone should automatically turn on after the firmware.

Important! This method erases all data from the phone. Use it only if other methods have not worked, and you do not have important information on the device. Also, do not flash the phone if you are not sure about the firmware model - this can lead to a blink (complete failure).

Method 5: “Hard” run through the test menu (for advanced users)

This method is only suitable for power users, as it requires working with Xiaomi’s engineering menu.It helps in cases where the phone is charging but does not turn on due to a failure in the firmware or power controller.

Instructions:

1. Connect the phone to the charger.
2. Type on the phone keyboard (if the screen is responsive) the code: ##4636## or ##3644633## (for new models).
3. In the menu that opens, select Battery Information.
4. Check the Battery Status setting, and if it shows Unknown or 0%, the battery controller doesn't recognize charge.
5. Select Reboot to Bootloader or Force Fastboot (if you have one).
6. After the restart, the phone should turn on in Fastboot mode. From there you can try reflashing the device or resetting the settings.

Warning: Not all Xiaomi models support these codes. On new devices (e.g. Redmi Note 12, POCO X5), the engineering menu may be blocked, and it is not recommended to change the settings in the Testing menu if you do not know their values - this can lead to irreversible crashes.

💡

If the phone only turns on in Fastboot or Recovery mode, but does not boot into the system, the problem is the firmware or damaged memory partitions, in which case only flashing through the Mi Flash Tool or accessing the service will help.

What to do if nothing helps: Diagnostics of malfunctions

If you’ve tried all the ways, but Xiaomi still doesn’t turn on, it’s likely that the problem lies in a hardware breakdown.

If you are not sure about the cause of the breakdown, contact an authorized service center Xiaomi. the cost of diagnosis is usually 500-1000 rubles, and repair (for example, replacing the battery) costs 1500-3000 rubles depending on the model.

Interesting fact: in 2023, Xiaomi launched the program "Safe battery", according to which owners of devices older than 2 years can replace the battery at a discount of up to 50%.
