Xiaomi Redmi 4 is one of the most popular budget smartphones of the brand, but even it is not immune to problems with switching on. The smartphone may not respond to the power button after a deep discharge, hang on the logo or not give signs of life at all. In this article, we will analyze all possible ways to turn on Redmi 4, from basic to emergency, as well as the diagnosis of typical malfunctions.
If your Xiaomi Redmi 4 doesn’t turn on, don’t rush to bring it to the service center. 80% of the time, the problem is solved by yourself – just know the right sequence of actions. We will look at both standard methods (charging, forced reboot) and advanced (Fastboot mode, reset via Recovery). MIUI.
1. Standard inclusion: what to do if the smartphone is discharged
The most common reason Xiaomi Redmi 4 doesn’t turn on is the battery drain. Even if you plug in the charger, the smartphone may not respond for 10 to 30 minutes. This is normal: the battery controller blocks the start until the minimum charge level is reached.
To properly charge the discharged Redmi 4:
- 🔌 Use the original cable and power adapter (5V/2A). Cheap analogues may not provide sufficient current.
- ⏳ Leave your smartphone on charge for at least 30 minutes.Do not try to turn it on earlier - this can cause the controller to crash.
- 🔋 If the charging indicator doesn't turn on after an hour, try another charger or cable.The problem may be the Micro-USB port.
- 🔄 After the charging indicator (red/orange LED) appears, hold the power button for 10-15 seconds to force it to turn on.
If the charging indicator doesn't burn even after a cable change, check the Micro-USB port for debris or oxidation. Carefully clean it with a toothpick (not metal objects!). In rare cases, the problem lies in a malfunction of the power controller - then repair will be required.
2. Forced reboot: if the smartphone freezes
If the Xiaomi Redmi 4 is stuck on the MIUI logo, black screen, or unresponsive to touch, a hard reset will help, which resets the current state of the system without losing data.
For forced reboot:
- Hold the power button and the volume button at the same time.
- Keep them clamped for at least 20 seconds – even if the screen is gone or a logo appears.
- Release the buttons when the smartphone vibrates and starts to boot again.
If the combination does not work, try an alternative method:
- 🔄 Hold the power button for 30 seconds (no volume buttons).
- 🔋 Connect the charger and try again.
- 📱 If the screen blinks but does not load, the problem may be in the damaged system partition (flashing required).
Check the battery charge (minimum 5%)
Turn off all cables (charging, headphones)
Make sure the buttons don't stick.
Wait 1 minute after the power outage-->
⚠️ Warning: If the smartphone is rebooted cyclically (hang) → restart → If you freeze again, it could indicate a firmware or hardware malfunction, and then a forced reboot won't help, you'll need to reset or flash it.
3. Running in Recovery Mode: Resetting settings
If Redmi 4 is turned on but not loaded beyond the MIUI logo, system files may be damaged, in which case resetting via Recovery mode will help, which removes all user data, but returns the smartphone to working condition.

5. Diagnosis of malfunctions: when the smartphone does not turn on at all
If the Xiaomi Redmi 4 is not showing signs of life (it does not vibrate, the indicator does not burn, does not warm up), the problem may be hardware.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| No reaction to charging, the indicator does not burn | Micro-USB port or power controller is malfunctioning | Replacement of port or fee in the service |
| Vibrates when connecting charging, but does not turn on | Short circuit on the battery | Battery replacement |
| It warms up when charging, but does not turn on | Failure of the processor or memory | Diagnostics in the service |
| The indicator blinks, but the screen is black. | Problems with the display or plume | Checking of illumination and contacts |
For self-diagnosis:
- Try connecting your smartphone to another power source (e.g., a power bank).
- Check if the case is warming in the area of the processor (center of the back panel) – if so, a failure in the chipset is possible.
- Connect to a PC – if the computer makes the device’s connection sound, the problem may be in the display.

6. Frequent User Errors and How to Avoid Them
Many of the problems with the inclusion of Xiaomi Redmi 4 arise from the wrong actions of users.
- 🔋 Use of non-original chargers. Cheap adapters can produce unstable voltages, causing the power controller to fail. Always use the power-out charger. 5V/2A.
- 🔄 Interrupt the upgrade process. If the smartphone is not fully updated and has frozen, do not force it to turn it off — wait for completion or reset via Recovery.
- 📱 Mechanical damage: impacts or falls may disrupt battery or display contacts. Avoid physical exertion on the body.
- 💦 Even if the smartphone doesn't turn off immediately, corrosion can occur in a few days.
Another common mistake is ignoring battery discharge signals, so if your smartphone is turned off at a charge level below 3%, the controller can block the start before recharging, and always monitor the battery level and avoid full discharge.
If you often experience hangings, check out:
- 📱 Is there enough free memory (less than 1 GB can cause crashes).
- 🔄 Are there no unofficial firmware or modified cores installed.
- 🛠️ Are there any corrupted system files (checking through Recovery will help).
7. Alternative ways to start: what to do if nothing helps
If the standard methods don’t work, try alternative approaches:
- 🔌 Charging from another source: Sometimes the smartphone does not respond to network charging, but turns on from a power bank or USB-PC port. Try different options.
- ❄️ Cool or heat: If your smartphone overheats, let it cool for 10 to 15 minutes; if it's too cold, warm it in your hands (but don't use a hair dryer or battery!).
- 🔋 Replacing the battery: If the battery is swelling or not holding the charge, replacing it can solve the problem.
- 📡 Connect to Mi Assistant. If your smartphone is detected by your PC in Fastboot mode but not flashed, try Mi Assistant to restore.
In extreme cases, if the smartphone is not turned on and not determined by the computer, only maintenance remains.The cost of diagnostics in official Xiaomi centers usually does not exceed 500-1000 rubles, and repairs cost 1500-3,000 rubles depending on the malfunction.
