Xiaomi Redmi 5 Plus does not turn on: what to do if the phone does not respond to the power button

Xiaomi Redmi 5 Plus is a popular smartphone with excellent value for money, but even it is not immune to sudden breakdowns. One of the most frightening situations for the owner is when the device stops turning on: the screen remains black, there is no reaction to charging or pressing buttons. The reasons can be both software (firmware failure, dead battery) and hardware (fab damage, contact oxidation).

It's important to understand that if the phone doesn't show signs of life, it doesn't always mean that it's a serious breakdown. In 60 percent of cases, the problem is solved by simple actions -- charging correctly, resetting the settings, or restarting in safe mode. But there are also critical scenarios where repairs are necessary. We structured instructions from the simplest to the most complex so that you can consistently rule out possible causes.

Before you start, prepare: a charger with cable (preferably original), a computer with Xiaomi drivers installed, and 10-15 minutes of time. If after all the manipulations the phone did not work, at the end of the article you will find a checklist for diagnosing hardware malfunctions.

1. Charging and battery check: first steps

Start with basic power supply diagnostics. Often the Redmi 5 Plus doesn't turn on because of a fully drained battery or charger issues. Connect your phone to the grid and notice:

• 🔌 Charging indicator: Does the light bulb (red/orange) burn when the cable is connected? If so, the battery takes charge, but the voltage may be too low to turn on.
• 🔋 Type of charger: Use the original power supply on 5V/2A. Cheap analogues may not provide sufficient current.
• ⚡ Cable problems: Try another one USB-cable (preferably fast charging) oxidation of contacts in the microUSB connector is a common cause of poor contact.

If the indicator is not on, try holding the Power button pressed 15-20 seconds — sometimes it helps to wake up the power controller. If there is no reaction, leave the phone charging for at least 30 minutes, even if it seems not to charge. Redmi 5 Plus batteries (with a capacity of 4000 mAh) can discharge to such a state that it takes time to start charging.

⚠️ Note: Do not use fast chargers from other brands (such as Samsung Adaptive Fast Charging or OnePlus Dash Charge). Xiaomi Power Controller may not correctly recognize voltage, which will lead to even more discharge.

If after an hour of charging the phone still does not respond, move on to the next step – checking the hardware components.

2. Hardware diagnostics: what can be checked independently

If the charging didn't work, there's a possibility that the problem is physical damage.

• 💧 Moisture traces: check the water intake indicator (white circle under the tray for SIM-If it turned red, there was contact with the liquid).
• 🔧 Battery Bloating: Put the phone on a flat surface and spin – if it is “walking” or the screen is raised, the battery could swell.
• 🔌 Damage to the microUSB connector: illuminate the port with a flashlight - are there any bent contacts or debris.

If you find a bloated battery, don't try to turn on the phone, it's dangerous! Take it to a battery replacement service. If you see any traces of moisture, you can try to dry the device in rice or silica gel for 24 to 48 hours, but the chances of recovery are slim.

If there is no external damage, but the phone still does not turn on, try a hard reboot:

1. Press the Power + Volume Up button for 10-15 seconds.
2. If the Mi logo appears, release the buttons and the phone will reboot.
3. If there is no reaction, repeat the combination by adding the Volume Down button.

⚠️ Attention: On Redmi 5 Plus with unlocked bootloader, long-term button retention can trigger Fastboot mode. If you see a hare in a hat-eared hat on the screen, it's normal, just release the buttons and wait 30 seconds.

3. Computer Connection: Diagnostics via Fastboot and EDL

If the phone doesn’t turn on but reacts to a PC connection (e.g., it makes a device connection sound), you can try to restore it through special modes. You’ll need a computer with Xiaomi drivers installed and MiFlash or Fastboot Tools programs.

First, check if the phone is detected in Device Manager:

1. Connect Redmi 5 Plus to your PC with a cable.
2. Open Device Manager (click Win + X → select option).
3. See if a device named Qualcomm HS-USB QDLoader 9008 (EDL mode) or Android Bootloader Interface (Fastboot mode) appears on the list.

If the device is identified as Qualcomm HS-USB QDLoader 9008, which means the phone is in emergency mode EDL. In this case, you can try to reflash it with MiFlash, but Redmi 5 Plus (codename vince) requires an authorized Xiaomi account to unlock the bootloader. EDL impossible.

If the phone is defined as Fastboot, you can try rebooting it in Recovery:

fastboot reboot recovery

Or reflash through Fastboot (without data loss):

fastboot flash boot boot.img


fastboot flash recovery recovery.img




fastboot reboot

⚠️ Note: Fastboot will reset all settings if you use the fastboot flash userdata command. Without it, the data remains intact, but the system files will be restored to factory.

4.Recovery through Recovery Mode: Reset and Update

If the phone vibrates or briefly lights up when you press the buttons, but does not load fully, try to enter Recovery mode.

1. Turn off the phone (if it is in a “hang” state, press the Power for 20 seconds).
2. Press Power + Volume Up and hold until the Mi logo appears.
3. Release the buttons when the Recovery menu appears (English or Chinese).

The following options are available in the Recovery menu:

If the phone is stuck on the Mi logo or is cyclically restarted (bootloop), it will help to clear the cache (Wipe Cache). If this does not work, you will have to reset (Wipe Data), but all data will be lost.

3. In the Recovery menu, select Install update.zip → confirm installation.
4. After completion, select Reboot.

5 Problems with iron: when without repairs can not do

If none of the software methods worked, it's probably hardware, and here are the most common Redmi 5 Plus malfunctions that require specialist intervention:

• 🔋 Faulty battery: even if the phone shows charging, the battery may not hold voltage.Symptoms - the phone only turns on from charging, but immediately turns off when disconnected.
• 🔌 Damaged microUSB connector: oxidation or break of contacts leads to unstable charging.
• 🔧 Burnt Power Controller: If the phone doesn’t respond to charging or buttons, there may be a chip problem PMIC (boardside battery).
• 💻 Damaged motherboard: Falls or moisture can cause a short circuit.

You can only replace the battery yourself (if you have experience disassembling phones).

1. Plug off the back cover (use a plastic shoulder blade to avoid damaging the plumes).
2. Disconnect the battery plume (it is glued to the motherboard).
3. Carefully tuck the battery and replace it with a new one (we recommend the original BM47 or ZMI analogue).

⚠️ Warning: When replacing the battery, do not use metal tools - risk short circuit! If the battery is swelling, do not puncture it - this can lead to fire.

Other malfunctions (power controller, board) require special equipment (multimeter, soldering station) if you are not sure of your skills, you should contact the service.

• Battery replacement: 1500–2500 ₽
• MicroUSB connector repair: 1000–2000 ₽
• Replacement of the power controller: 3000–5000 ₽
• Diagnosis of the fee: 500-1500 ₽

💡

Before visiting the service, take a picture of the IMEI phone (printed on the box or under the battery) to help avoid replacing components.

6 Prevention: How to avoid recurring problems

To make the Redmi 5 Plus last longer without crashes, follow these guidelines:

• 🔋 Charging: Use only original or certified chargers. Don't leave your phone charging overnight - this shortens battery life.
• 🌡️ Temperature: Avoid overheating (do not play heavy games when charging) and hypothermia (do not leave your phone in the cold).
• 💧 Moisture: Even if your phone isn't afraid of splashing, don't use it in the rain or in the bathroom.
• 🔄 Updates: Install updates regularly MIUI — They correct errors that can lead to hanging.

It is also useful to clean the cache every 2-3 months through Recovery (without resetting data), which prevents the accumulation of debris that can cause download failures.

If the phone starts to slow down or reboot spontaneously, these are the first signs of future problems.

1. Check the space in the memory (should be at least 10% of the total).
2. Remove unused apps (especially those that work in the background).
3. Turn off animation in the developer settings (path: Settings → About Phone → MIUI version (click 7 times) → Developer settings → Animation scale).

💡

Regularly cleaning the cache and updating the firmware reduce the risk of software failures by 40%.

7. Alternative methods: non-standard solutions

If the standard methods don’t work, you can try the less obvious options:

• 🔌 "Lighting from another battery: If you have a second Redmi 5 Plus (or similar model), you can temporarily connect its battery to a broken phone.
• ❄️ Cooling/heating: If your phone overheats and shuts down, put it in a cool place for 10-15 minutes. If it doesn’t turn on in the cold, warm it up for 5 minutes (don’t use a hair dryer or battery!).
• 🔊 Sound signal: When connected to charging, some Redmi 5 Plus will squeak quietly (if you insert headphones) This is a sign that the phone is getting power, but the screen is not working.

Another way is through Test Point, which is an extreme measure that requires disassembling the phone and closing the contacts on the board to force you to enter EDL mode.

1. Remove the back cover and disconnect the battery.
2. Find Test Point (two metal dots next to the microUSB connector, signed EDL).
3. Close them with tweezers and connect the phone to a PC – it should be defined as a Qualcomm HS-USB QDLoader 9008.
4. Sweat your device through MiFlash (requires an authorized account).

⚠️ Note: Close Test Point without experience can damage the board.This method is recommended only if you are confident in your actions or under the guidance of a specialist.
