Why Xiaomi Redmi 6A is not included: a full analysis of the causes and solutions

What to do if the Redmi 6A is not showing signs of life

You pressed the power button, but the Xiaomi Redmi 6A screen is still black, the light doesn't blink, and the phone doesn't vibrate? This is a situation that many owners of a budget smartphone released in 2018 are familiar with. The causes can range from a trivial battery discharge to serious hardware malfunctions. It's important to understand that not always "not on" means a breakage. In 60% of cases, the problem can be solved independently without resorting to the services of the service center.

In this article, we will look at all possible scenarios, from the simplest (e.g., system freeze) to the most critical (motherboard damage), how to diagnose a malfunction, what manipulations are safe to perform at home, and when to consult a specialist. Special attention will be paid to the characteristic “symptoms” of the Redmi 6A, which help to determine the root of the problem, for example, a flashing red indicator when charging is connected often signals a battery malfunction, and the lack of a charging response to a power controller problem.

Before you start the diagnosis, prepare:

✔ Charger with cable (original or certified).

✔ Computer with Qualcomm drivers installed (for firmware).

✔ Multimeter (if you plan to check the battery voltage).

✔ Torx screwdriver. T3 and plastic blade.

1. discharged battery: how to distinguish from a breakdown

The most common reason is deep battery drain. The Redmi 6A has a 3,000 mAh battery that loses capacity over time. If the phone has run out to 0% and has been in this state for several days, the power controller can block charging, in which case a standard network connection will not help.

How to check: Step 1. Connect the original charger (or with output) 5V/2A) Leave it on 30–60 Don't press the power button, wait for the charging indicator (red or orange LED) to appear. 2. If the light doesn't turn on, try another charger or cable. Sometimes the problem is the damaged one. USB-port or oxidized contacts. 3. Connect your phone to your computer through USB. If the computer makes the device connect sound, but the screen remains black, the problem is the display or plume.

• 🔋 Charging indicator flashes red, phone warms slightly when connected to the network.
• ⚡ Signs of battery failure: indicator does not burn, phone does not warm, no reaction to charging.
• 🔌 Signs of a port/cable problem: Charging indicator only lights up in a certain position of the cable.

⚠️ Warning: If the phone does not respond to charging for more than a day, do not try to light it from another battery or apply increased voltage - this can disable the power controller.

System freeze: how to perform a forced reboot

If the Redmi 6A is stuck on the Mi logo, the screen flickers or the phone reboots in cycles — a problem most likely software — this can happen after a system update, installing an incompatible application, or a malfunction of the Qualcomm Snapdragon 430 processor.

How to Reboot Forced: Method 1. Press the power button for 10-15 seconds. If the phone vibrates but the screen doesn't turn on, there's a problem in the display or backlight. Method 2. If the standard reboot doesn't help, try the combination: Power button + Volume up (hold 20-30 seconds). Method 3. To reset to factory settings via Recovery:

If the phone doesn't turn on after the reset, the firmware may be damaged, in which case you'll need to reflash the device via Fastboot or EDL-mode (emergency loading mode).

💡

If the phone has been frozen after the MIUI update, try to roll back to the previous version via Fastboot. To do this, download the official firmware from the Xiaomi website and use the MiFlash utility.

Battery problems: how to check and replace

The average life of a Redmi 6A battery is 2-3 years, and then the capacity drops by 30-50%, and the power controller can block charging.

How to check the battery without disassembling: Method 1. Connect the phone to charge and touch the back cover. If it is hot, you can overheat the battery or short circuit. Method 2. Use the AccuBattery app (if the phone is even occasionally turned on). If the battery is below 60% healthy, it's time to change it. Method 3. Check the voltage with a multimeter:

1. Unscrew the phone (unscrew 8 Torx T3 screws and slap the back cover with a plastic spatula).
2. Connect the multimeter to the contacts of the battery (black probe to minus, red to plus).
3. Normal voltage - 3.7-4.2V. If below 3.3V - the battery is discharged to zero and requires "swinging" with a special device.

⚠️ Warning: If the battery is swelling, don't try to puncture or heat it - it can cause a fire.

The cost of a new battery for the Redmi 6A is from 500 to 1200 rubles. You can replace it yourself, but you need to be careful: do not damage the display plumes and buttons.

4 Damage to the charging port or power controller

If the Redmi 6A does not respond to charging, but the battery is working properly, the problem may lie in:

• 🔌 Charging port Micro-USB: oxidation of contacts, mechanical damage or dumping of soldered tracks.
• 🔧 Power controller PMIC: chip responsible for voltage distribution (located on the motherboard next to the port).
• 🔋 Battery plume: oxidation or break of contacts.

How to diagnose: Test 1. Connect the charging and slightly move the cable in the port. If the charging indicator lights up in a certain position, there is a problem in the port. Test 2. Check the voltage on the port contacts with a multimeter (should be 5V when connecting the charging). Test 3. If the port is visually damaged (bent contacts, traces of oxidation), it can be replaced yourself. The cost of a new port is 200-400 rubles.

If the problem is in the power controller (PMIC), You will need a soldering station and experience with BGA-In most cases, it is cheaper and safer to contact the service. The average cost of repairing the controller is 1500-3,000 rubles.

💡

If the phone is not charging but is powered by the Power Bank (external battery), the problem is precisely in the charging port or cable.

5. Damage to the motherboard: when repair is impractical

The worst case scenario is a motherboard failure, and it could be because of:

• 💦 Moisture intrusion (even if the phone is not sinking, condensation inside the case can cause corrosion).
• ⚡ Voltage drops (for example, when using uncertified chargers).
• 🔥 Overheating (often when playing or charging in a hot room).
• 🛠️ Mechanical damage (fall, impact, strong vibration).

Signs of fee breakdown:

• The phone does not turn on, does not warm, does not respond to charging.
• When connected to a computer, it is not defined as a device.
• There are traces of oxidation or burnt elements on the board.

Diagnostics of the board requires disassembling the phone and visual inspection. Note: 1. Capacitors - if they swell or leak electrolyte fluid, they need to be replaced. 2. Tracks - check the integrity of soldered joints (often the contacts of the battery or display depart). 3. Microcircuits - if they have black dots or melts, this is a sign of short circuit.

⚠️ Attention: repair of the Redmi motherboard 6A The cost of work can exceed 5000 rubles, which is comparable to the price of a new budget smartphone, in which case it is more logical to consider the option of buying a replacement.
