Why Redmi Note 8 may not turn on and what to do about it
Xiaomi Redmi Note 8 is a reliable device, but even it sometimes refuses to start. The reasons range from a trivial battery discharge to serious software failures. Before you panic and carry the phone to the service center, check the highlights: is the charger connected, is the cable damaged, is the device overheated. 80% of the time, the problem is solved by simple actions, which we will discuss below.
If your Redmi Note 8 doesn't respond to the power button, it's not a cause for frustration. It may have gone into a deep discharge (when the charge is below 3%) and requires recovery time, or it's got stuck due to an application conflict. In this article, we'll look at all possible scenarios, from standard on, to forced reboot and exit from Fastboot mode.
We'll focus on situations where the screen is black, but the phone vibrates or makes sounds, and this signals all kinds of malfunctions, from damage to the plume of the display to a firmware failure, and we'll teach you to distinguish between "soft" problems (solved on your own) and "hard" problems (requiring intervention from specialists).
Standard Incorporation: Step-by-step instructions
If youβve just bought a Redmi Note 8 or havenβt used it in a while, start with a basic power on. Make sure the battery is at least 5% charged β otherwise the smartphone wonβt respond to the push of a button.
Charge your phone for at least 15 minutes with the original charger
Check that the cable is not damaged and is tightly inserted into the connector.
Make sure the power button is not stuck (wiggle your finger)
Disable all peripheral devices (earphones, memory cards)-->
Now, do the following:
- Press the power button (located on the right side edge) for 3-5 seconds until the Redmi logo appears.
- If the screen is black, wait 10 seconds and try again, and sometimes the system needs more time to initialize.
- When successful, enter PIN-code or pattern lock (if installed).
If the MIUI logo says "Android recovery" or the smartphone goes into reboot, it's a sign of damage to system files, then go to the section about recovery through Recovery.

If the phone turns on but shuts off, check the battery status, it may have swelled or lost capacity, and you need to replace it.
Forced reboot: When the power button doesn't work
There are situations where the Redmi Note 8 is stuck on the logo, the screen goes out, or the device doesn't respond to the press, and in these cases, a hard reset that simulates battery extraction helps, and this is a method that is safe for data unless you switch to resetting.
Here's how to do it:
- Press the power button + volume button at the same time.
- Hold them for at least 10-15 seconds until the screen goes out and the Redmi logo lights up again.
- Release the buttons β the phone should start loading in normal mode.
If the combination does not work, try an alternative:
- π Power button + Reduce volume (hold 10 seconds).
- π Power button only (hold 20-30 seconds for full power outage).
What if the phone vibrates but the screen is black?
After a forced reboot, the phone can boot longer than usual (up to 2-3 minutes).
Recovery through Recovery Mode
If the Redmi Note 8 is turned on but not loaded beyond the logo, or is rebooted cyclically, itβs time to activate Recovery Mode, a tool that lets you reset settings, clear the cache, or reflash the device.
To enter Recovery:
- Turn off the phone (if it is on, hold the power button until it is turned off).
- Press the power button + increase the volume.
- When the Mi logo appears, release the power button, but keep holding the volume up until you see the Recovery menu.
The following options are available in the recovery menu (management is carried out by volume and power buttons):
- π± Reboot β Reboot your phone (try this first).
- π§Ή Wipe Data β Complete reset (deletes all data!).
- ποΈ Wipe Cache β Cache Clearance (Secure for Data).
- π§ Connect with MiAssistant β Connect to a PC for firmware.
π‘
Cache cleaning is the first step when you freeze, and it doesn't delete personal data, but it often solves download problems.
If you chose Wipe Data, the phone will return to factory settings after the reset, and you'll need to reconfigure it, just like you did after you bought it. Importantly, before you do that, try connecting your phone to your PC and backing it up with the Mi PC Suite.
Getting out of Fastboot mode
Fastboot mode (also known as Bootloader) is used to run your phone through your computer, and sometimes the Redmi Note 8 spontaneously enters this mode after a failed update or failure, and you can recognize it by labeling it "FASTBOOT" on a black screen and connecting it via a USB icon.
To get out of Fastboot:
- If this doesnβt work, press the power button + volume reduction for 10 seconds.
If the phone is constantly loading into Fastboot, this may indicate:
- π Damaged firmware (requires flashing through Mi Flash Tool).
- π Faulty battery (try charging your phone with another charger).
- π οΈ Hardware failure (requires diagnosis in the service).
Yeah, a few times.
Yeah, but once.
No, never.
I don't know what that is.-->
Battery problems: When the phone doesn't respond to charging
One of the most common reasons why the Redmi Note 8 doesn't turn on is because the battery is so low that if the charge drops below 3%, the power controller blocks the start to avoid damaging the battery, and in those cases, standard charging might not help, it might need a push.
Here's what to do:
- Connect the phone to the original charger (at least 18 watts).
- Leave it to charge for at least 30 to 60 minutes, even if the indicator is not on.
- Try turning on your phone by holding the power button for 10-15 seconds.
- If the charging indicator does not light up, try another cable and power supply.
If after an hour of charging the phone still does not show signs of life, the problem may be:
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The indicator is not burning, there is no vibration. | Faulty cable/charger or portable battery | Try a charger from another phone |
| The phone is warming up, but it won't turn on. | Short circuit in the battery | Disconnect from the network immediately, contact the service |
| The indicator flashes red. | The battery is swelling or has lost capacity | Battery replacement (cost ~1500-2500 rubles) |
| Charging is underway, but the phone turns off when the cable is turned off. | Battery wear (capacity < 50%) | Diagnosis through AccuBattery or replacement |
π‘
If the phone is not responding to charging, try connecting it to a powerful power source (such as a laptop charge or a power bank at 20,000 mAh).
If none of the methods worked and the phone still doesn't turn on, the power controller may have failed, in which case repairs at Xiaomi's authorized service center will help.
What to do if nothing helps
If youβve tried all of these and the Redmi Note 8 still doesnβt turn on, itβs time to consider more serious measures.
- π Check the phone for battery bloating (put it on a flat surface β if it swings, the battery swells up).
- π§ Make sure the device has not been exposed to moisture (check the moisture indicator in the tray for SIM-map).
- π Try connecting your phone to your PC β is it determined in Device Manager?
- π± If the screen is broken, but the phone vibrates when you press the buttons β the problem in the display module.
If you are sure that the problem is software (for example, after a failed update), you can try to reflash the phone via Fastboot.
- A computer with Xiaomi drivers installed and the Mi Flash Tool program.
- Original firmware for Redmi Note 8 (download from the official Xiaomi website).
- USB-cable (preferably original).
How to check if your phone is alive without a screen?
If you are not sure of your abilities, it is better to consult specialists. The average cost of diagnosis in service centers is 500-1000 rubles, and repair (for example, replacing the battery or display) will cost 2000-5000 rubles, depending on the malfunction.
