Your Xiaomi Redmi 8 is no longer on and you donβt know what to do? This problem is familiar to many owners of budget Xiaomi smartphones, especially after 2-3 years of active use. The reasons can vary from a trivial battery discharge to serious hardware malfunctions. In this article, we will analyze all possible scenarios why the Redmi 8 does not respond to the power button, and give step-by-step instructions for diagnosis and recovery, from simple actions to complex technical manipulations.
It's important to understand that if the phone doesn't show signs of life (it doesn't vibrate, it doesn't light up, it doesn't warm up), it doesn't mean it's dead. In 60 percent of cases, you can solve the problem yourself without having to use a service center, but there are also critical symptoms that you should call a specialist right away, such as if the smartphone fell into the water or was subjected to heavy mechanical stress.
We structured the material so that you can move from the simplest to the more complex, starting with the first section and consistently checking each item, which will save you time and nerves.
1. Charging Check: Why Redmi 8 may not respond to network connection
The first thing to do is make sure that the problem is not a dead battery or a faulty charger, and even if you "know" that the charge is good, check it again with the following scheme:
- π Get Redmi on board. 8 to the original charger (18W) Leave it on 30-40 Sometimes a deeply discharged battery shows no signs of charging in the first few minutes. 10-15 minute.
- π Try a different cable and power supply.It is better to use a charge from Xiaomi or a proven brand (like Anker or Baseus).
- π‘ Connect your smartphone to your computer through USB. If the computer makes the deviceβs connection sound, the problem may be in the screen or plume.
- π Check the charging port for debris or oxidation. Clean it carefully with a toothpick (not a metal object!).
If you don't turn on after this manipulation, move on to the next step, but first, look at the charging indicator: if it flashes red or white when you connect to the network, this may indicate a specific problem (see the table below).
| Color of indicator | Frequency of flashing | Possible cause | Recommendations |
|---|---|---|---|
| Red (constantly) | No flashing. | Deep battery discharge | Leave on charging 1-2 hours, then try to turn on |
| Red. | Slow blinking (1 time in 2 seconds) | Insufficient charging current | Try another cable/power supply |
| White | Fast blinking (2-3 times per second) | Short circuit or battery damage | Battery replacement is required |
| No indication. | β | Failure of the motherboard or power controller | Diagnostics at the service center |
β οΈ Warning: If the phone is warming up while charging but not turning on, disconnect it immediately! this may indicate a short circuit in the battery - a risk of fire!
2.Forced reboot: how to 'wake up' the getting stuck Redmi 8
If the Xiaomi Redmi 8 doesnβt respond to the power button, but youβre sure the battery is charged, itβs possible that the system just βhangs.β This is a common problem after upgrades or when RAM is overloaded.
For Redmi 8, the procedure is as follows:
- Press and hold the Power + Volume button at the same time.
- Hold them for at least 15-20 seconds (even if the screen is unresponsive).
- If the Xiaomi logo appears, release the buttons and the phone will start to reboot.
If this method doesnβt work, try an alternative combination:
Power button + Volume button (hold 20-30 seconds)After a forced reboot, the phone can turn on in one of the modes:
- π± Normal mode β if the problem was temporary failure, the smartphone will boot as usual.
- π§ Fastboot (black screen with a rabbit and the words Fastboot) β additional actions will be required (see section 4).
- π€ Recovery mode (menu with items in English) - you can try resetting settings (section 5).
β οΈ Warning: If the phone turns on after a forced reboot but immediately turns off or overheats, this may indicate a malfunction of the battery or motherboard!

3.Diagnostics of hardware malfunctions: when the "iron" is to blame
If the Redmi 8 is showing absolutely no signs of life (it doesnβt vibrate, it doesnβt warm up, it doesnβt light up), the problem is probably hardware.
| Malfunction | Symptoms | Can I fix it myself? |
|---|---|---|
| Faulty battery | The phone does not turn on even after a long charge, sometimes bloated body | Yeah (battery replacement) |
| Damaged power plume | Charging indicator flashes, but the phone does not turn on | No (needs a soldering iron) |
| Short circuit on the motherboard | The phone is warming, the smell of burning may appear | No (diagnosis required) |
| Faulty power controller | The phone does not respond to charging, but sometimes switches on from connecting to a PC | No (complex repairs) |
| Damaged charging connector | Charging is only in a certain position of the cable. | Yeah (replacement plug) |
The most common hardware problem with Redmi 8 β This is due to the natural wear and tear of lithium polymer batteries after the battery is bloated. 300-500 Charging cycles:
- π The phone body began to βpullβ (especially noticeable from the screen).
- π The phone is running out quickly (less than a few minutes later). 2-3 hour) or switch off when 20-30% charge.
- β‘ When charging, the phone warms up strongly.
If you've confirmed that the battery is bloating, you can't keep using the phone -- it's dangerous! The swelling battery can damage the screen or even ignite, and in that case, you need to change it urgently.

Fastboot mode: what to do if Redmi 8 is stuck on the logo
If the phone is forced to reboot and is in Fastboot mode, it means that the system can't boot properly, and there are many reasons:
- π Failed firmware update.
- ποΈ Damage to system files.
- π οΈ Incorrect recovery from the backup.
In this mode, you can try to reflash your phone or reset your settings. Here's what to do:
- Connect Redmi 8 to your computer via USB.
- Download and install the Mi Flash Tool (the official utility from Xiaomi).
- Download stable firmware for Redmi 8 (codenamed olive) from the Xiaomi Firmware Updater website.
- In Mi Flash Tool, select Clean All mode and specify the path to the downloaded firmware.
- Press Flash and wait for the process to complete (5-10 minutes).
If the firmware is successful, the phone will restart normally, and if it is not, it may be memory damage (EMMC) or hardware problems.
β οΈ Attention: Fastboot firmware erases all data on your phone!If you had important files, try extracting them through the phone first ADB (If the phone is determined by a computer).
π‘
Before the firmware disable the antivirus β it can block the work of the Mi Flash Tool, taking it for malware.
5.Reset via Recovery: Last chance before firmware
If the phone turns on but doesnβt load beyond the Xiaomi logo, or reboots constantly, try resetting through Recovery Mode. This method saves the chance to restore performance without completely flashing.
To enter Recovery:
- Turn off the phone (if it is on, press Power + Volume Up for 10 seconds).
- Press Power + Volume Increase and hold until the menu appears.
- Use volume buttons for navigation and power button for selection.
From the Recovery menu, select:
- Wipe Data β Wipe All Data (complete reset).
- Reboot β Reboot to System (Reboot).
If the phone boots after reset, but some features are not working properly (for example, the camera or sensors are not working), this may indicate firmware damage.
π‘
Recovery resets don't always help if the problem is in corrupted system files, which requires a complete firmware reflash.
6.When to contact the service: signs of serious malfunctions
If none of these methods worked, it's probably hardware, and here are the red flags that make self-repairing useless or dangerous:
- π₯ The phone is warmed even when turned off (the risk of fire!).
- π§ There was contact with water or other liquid (even if everything was dry on the outside).
- β‘ After the fall, the phone stopped turning on (may damage to the motherboard).
- π The battery swelled or deformed the body.
- π΅ The phone is not detected by the computer even in Fastboot mode.
Average cost of repair Redmi 8 in service centers (2026):
| Type of repair | Cost (β½) | Date(days) |
