Redmi Note 5 White Light Blinking only Problem Solution

note 5 white light blinking

Redmi note 5 white light blinking is a very often problem nowadays. It happens due to many types of faults.

In this article, I will guide you on how to repair the dead Redmi note 5 white light only blinking when the charger is connected.

Possible Faults why Redmi Note 5 white light blinks:

1. Faulty Battery

2. Faulty PMI IC

3. Processor / SoC Dryness

4. Programming error in EMCP

Let’s discuss it one by one.


If your Redmi Note 5 mobile’s white light is blinking while charging, first check the battery voltage.

The battery voltage should be more than 3.75V. If the battery voltage is less than 3V, try to boost the battery voltage up to 3.8V using DC Power Supply Or Battery Activator.

When the battery voltage goes below 2.8V, a normal charger cannot charge the Battery. This results in white light blinking in Redmi Note 5. You need to boost the battery using Battery Booster or DC Power Supply to 3.8V.

There is already a dedicated lesson about the topic.

Now try to switch it on.

Sometimes though the Battery voltage is Ok, it does not power on the mobile phone due to high internal resistance in the Battery Protection Circuit.  It does not supply the required current. So you must try another good Battery Or repair the old Battery.

If your mobile turns on normally with a new or repaired Battery, then your problem is solved. If not, follow the next step.


There are two Power Management Integrated Circuits (PMICs) in Redmi Note 5 Motherboard. 

  • Primary Power IC (PM660)
  • Secondary Power IC (PMI8952)

If this secondary power IC PMI8952 is faulty, the white light blinking problem arises. This is installed near the Processor.

First, try to reflow PMI8952 and check whether Redmi Note 5 is turning on or not.

If not turning on, replace it with new PMI8952. It should solve your problem.

Processor / SoC dryness

If the above methods don’t work, heat the Processor at 360°C for 3 minutes using Hot Air Machine. Sometimes the balls under SoC or processor get dry soldered. So when you heat the SoC, the balls will be connected with the bonding pads again.

The good part is there is no white glue or black glue pasted in the CPU. You can easily reflow it without removing it.

Programming Error in EMCP

EMCP is the memory IC which is the combination of RAM and ROM.

When any mobile runs for a long time about 2 to 3 years, there are some errors coming like ‘consumed 90% of the reversed blocks’, ‘MLC and SLC mismatched percentage’.

You need to have Emmc Programming Box like UFI Box, and Easy Jtag Box to detect and repair Redmi Note 5 white light blinking problem.


In this way, the white light blinking problem can be repaired in Redmi Note mobile phone.

Hi, My name is Rajesh Behera. I am the founder of RepairTheMobile. I am a Mechanical Engineer and currently working in an MNC. Mobile phone repair is my passion. There are a lot of mobile phone repair videos available on YouTube. But most of these videos are not properly explained due to the lack of proper knowledge of the technicians. Due to the demand for mobile phones, lots of new mobile technicians are opening their repair shops. They are only doing basic works like combo (display screen) replacement, charging port change, battery replacement, etc. They don’t know the proper way of finding faults like dead phone repair, backlight & graphics issues, network problems etc. They cannot close their shops to get offline training. So, I decided to make RepairTheMobile to help new mobile technicians. RepairTheMobile is absolutely free learning platform. It offers FREE mobile repair training from basic level to advanced level. Keep learning & keep earning.
