noreply@blogger.com (Muhammad Asif Azeemi) — Sat, 26 Apr 2025 17:02:00 +0000

When the customer comes to you with a Redmi phone and says that the phone is switched off by itself automatically. That is a common issue with Redmi 9 Prime, the phone automatically turns off during use or while booting up. This frustrating issue is also a common problem in Poco M2 smartphone models. This problem is fixed by mobile phone technication using an intelligent trick.

Redmi 9 Prime Poco M2 Auto Switch Off

🚨 Redmi 9 and Poco M2 Common symptoms of auto switch off:

The phone automatically switches off during use. When immediately put on charge, it gets hot.
When we check phone charging on a USB ampere tester charger, the phone shows charging stats as normal.

Automatically switches off

This problem often goes unnoticed until tested on a DC power supply, where the Redmi 9 Prime begins to draw high amperage, indicating a hardware-level short circuit.

Redmi 9 and Poco M2 Dead Condition Cause

The dead condition in the Redmi 9 Prime is caused by a faulty resistor near the 4G Power Amplifier IC on the phone's motherboard signal section. When the resistor is shorted or damaged, the phone starts consuming high amperage during charging, leading to unexpected shutdowns. Below is a comprehensive guide to understanding and resolving this dead condition with a professional repair method.

Fixing Samsung A12 Charging Slowed Due to Low Temperature

noreply@blogger.com (Muhammad Asif Azeemi) — Sun, 13 Apr 2025 10:40:00 +0000

If you've plugged your customer's Samsung phone and met with a strange thermometer icon or a warning that the phone is "too cold to charge," that is a common error. This frustrating issue is known as a thermal error, and it's particularly common in models like the Samsung A12 (sm A125f). Many mobile technicians take the same model for repair in Samsung a12 charging slowed due to low temperature problem. This error is repairable with a bit of intelligence and the right tools.

Samsung A12 Charging Slow Problem Symptoms

🚨 Common Symptoms of the Thermal Error:

When pressing the phone's power button, the Phone displays a thermometer symbol inside a triangle.
Warning message: "Temperature is too low. Charging will resume when temperature returns to normal."
Samsung A12 Charging error
The phone doesn't turn on, or when put on charge, it gets stuck on the battery symbol.
Most mobile technication perform shortcut technique to fix this error. They remove components from the phone circuit, but the error turns into fake charging.
When checking charging on a 6 port usb charger, Charging starts briefly (around 1.4A) and then drops.

Samsung A12 charger error

Why is My Samsung A12 Charging Slowly

Customers usually ask this question. To answer it, you can tell the customer that it seems that there is a problem with the sub-board circuit of your phone. This problem can also be caused by components. Give me permission to open the phone so that I can check it and tell you if any component is damaged or if there is a problem with the thermal circuit of the phone.

🧵 Root Cause: Faulty Thermal Circuit:

Samsung Galaxy phones monitor temperature using an NTC thermistor (Negative Temperature Coefficient resistor) that works with a fixed resistor to create a voltage divider circuit. If the NTC thermistor is damaged or reads incorrectly, the phone may think the battery is too cold (or hot) and halt charging as a safety precaution.

Components Involved:

R1: Fixed resistor (typically 100kΩ)
R2: NTC thermistor (also around 100kΩ at room temp)

why is my samsung a12 not charging

Both components send signals to the CPU IC in the phone via a thermal input line. Any irregularity triggers the error.

Here's a comprehensive step-by-step guide to understanding and resolving the thermal error issue.

Samsung A12 Charging Slow Problem Step-by-Step Repair Process

🔍 Step 1: Observe Charging Behavior

Use a 6 port USB charging or DC power supply charging meter:
Note the initial amp draw.
See if the current drops quickly or stays steady.

Samsung A12 charging error problem solution manual

🌐 Step 2: Visual Inspection

Open the device carefully.
Locate the resistors near the mic section or charging port.
Inspecting for damage, corrosion, or discoloration.

⚖️ Step 3: Voltage Check Using a Digital Multimeter:

R1 (Fixed Resistor) should show ~1.8V.
R2 (Thermistor) should show reduced voltage (~0.9V).
If either side shows abnormal values, one of the components may be faulty.

How to measure resistors

🔢 Step 4: Resistance Measurement Switch Multimeter to Ohm Mode:

R1: ~100kΩ
R2 (NTC): ~100kΩ at 25°C; lower if it's been heated.
If the thermistor reads <30kΩ at room temperature, it's defective.

Samsung A12 Slow Charging Jumper❌ What NOT to Do: Bypassing the Circuit

Some YouTubers' mobile phone technication suggests removing R1 and R2 completely to bypass the error. This may eliminate the thermal warning, but it causes a fake charging battery symbol to appear, but no real charge flows. It’s not a real fix and can harm the phone further.

samsung a12 slow charging jumper solution

Why is My Samsung A12 Charging Slowly Fix ✅ Proper Fix: Replace Faulty Components

Replace R1 with a new 100kΩ resistor.
Replace R2 with a proper NTC thermistor.

Can't you find the exact NTC? Use a fixed resistor between 47kΩ and 68kΩ as a temporary simulation to complete the voltage divider and remove the error.

Find resistance by searching TH in schematic PDF

You can find this resistance from the schematic diagram of any Samsung mobile phone, J series, S series, or A series. You can take it from the scrap circuit you have and put it in your customer's circuit and fix his mobile.

Reading Schematic Tool Hardware Solution diagrams To Trace Faults

First of all, To address the issue with the malfunctioning phone, access the folder for the specific phone model in the tool. Once you have accessed the folder, you can proceed with the necessary steps to diagnose and solve the problem.

Hardware solution folder in Borneo

For example, in the Borneo Schematic Tool. open the hardware solution folder, then the phone brand folder after that click on the phone model.

Phone brand and phone model folder

In this, when we click on the model, some PDF appears in front of us which is made fault-wise,

Fault Finding Diagrams

But the first PDF we use in this is the one of diode. When we click it, it shows a multimeter list. you should have a four-digit multimeter.

Diode mode PDF file in Borneo

If there is a charging fault in the phone, then we have to see the V bus line GR reading in the tool.

Charging jack V bus line GR reading

Now open the PDF file in the folder and zoom the charging jack to read the V bus line in the file.

Use Four digit Digital Multimeter in Taking GR Reading

Now set the multimeter on diode mode, then put the red probe on the PCB ground and touch the black probe in the charging jack Vbus line. Now read the GR reading on the multimeter.

Testing charging jack with multimeter

Note: Compare the GR reading with the PDF file.

Fault Wise Multimeter Readings in Fault Tracing

Compare multimeter GR reading

On the multimeter screen reading scale, three types of readings can appear if the GR reading is not normal.

No Reading.
Reading is coming less.
Reading is coming too much.

No Reading: it appears when the V bus line is open.

Reading is coming less: We will check the leakage inside the V bus line. From the charging jack to Charging IC some electronic components are leaking current. Because of this, when you connect the charger to the mobile, it will not show anything, it will show you as if the charger is not connected.

Reading is coming too much: We will check the short circuit in the V bus line. It can happen that the charging jack, or the V bus line components diode, capacitors, and charging IC positive have connected with the PCB ground. In this situation, when you plug the charger into the mobile, it is possible that the charging IC may be hot or any component connected in the line may be hot. For a thorough understanding, watch the YouTube video below that covers different types of GR reading.

So these are the Readings that can appear when we start taking GR reading in the PCB line on the mobile phone. First of all, we have to see in the line whether our GR reading is normal or not. If the GR reading is not normal then we have to start testing. If the GRreading is normal then it is a software issue in the mobile. Generally, the GR reading is not good, hence the mobile comes to us for repair. First, we open the diode diagram and check the GR value. After that, as if we were giving the example of a charging fault in the mobile phone, then next we open the charging data PDF file in the diagram tool.
