Why doesn't my phone turn on and the charging indicator blinks?

Xiaomi's indicator blinks and does not turn on.

Xiaomi smartphones have several light indicators built into them. Some indicators indicate simple malfunctions, but some may indicate a serious breakdown of the smartphone. In a critical situation, you cannot do without the help of specialists, so to restore it you will need to contact a phone repair service. Today we will look at the main ways to solve a problem when the indicator blinks, but the phone refuses to turn on. We will repair xiaomi redmi 6s, spare parts are in stock, we have selected convenient operating modes.

For best results, use only the AC adapter and USB cable that came with your smartphone to charge the battery. If the battery is very low, be sure to use the AC adapter to charge rather than connecting to a computer via a USB cable. Note: Some phones do not have an LED indicator.

If there is no on-screen indicator, the charging indicator should appear on the screen when you press the POWER button. If your phone won't charge or turn on, follow these steps:

Press and hold the VOLUME UP, VOLUME DOWN, and POWER buttons for up to two minutes or until the phone vibrates.
Check for signs of your phone charging.
If the LED light is blinking, the phone is charging but will not turn on until the LED light turns solid. Wait until the LED indicator turns solid and then try turning on the phone.

In some cases, the charger may detect that the voltage is too low and stop charging the phone despite being plugged into the outlet.
System updates will help solve this problem. Update your phone regularly. Follow these steps:

Go to Settings > About phone > Software updates. The exact path may vary depending on the phone.
Standard path options.
Settings > System updates > HTC Software Update
Click Check Now to check for updates.
If the update is not found, confirm that you have the latest software on your phone. Go to Settings > About phone > Software version.

Damage to the charging port, cable, or AC adapter can also cause charging instability (for example, charging only in certain positions or only in the hand), or the device will not charge at all. To check if the problem is caused by a faulty cable or adapter, follow these steps:

Check the charging connector for damage or foreign particles; Bent plug contacts, dirt or fibers may block the connector.
Check the cable and adapter you are using for damage, such as kinks or frayed cables, or bent plug contacts.
Use a different charger with the appropriate voltage and current ratings for the device; Please note that some USB ports do not provide sufficient power for charging.

Turning your phone's power off and on again may resolve the issue. Follow these steps:

Press and hold the POWER button until the Phone settings menu appears.
Tap Power off and wait until your phone turns off completely.
Wait a few seconds and turn on the phone by pressing and holding the POWER button.

Check if the device can charge in safe mode.

Solving the problem

Let's consider the possible causes of the problem and directly effective solutions. If you are completely unfamiliar with smartphones, follow each instruction in order.

Full discharge

The first case is when the phone blinks red due to a completely dead battery. This happens in cases where owners throw a smartphone into a “shelter”, trying to bring it back to life in a few weeks/months.

The nature of the failure is simple - the battery has completely lost energy, which does not allow even the most basic startup of the system. This provokes “indifference” to the power key.

First, connect your phone and wait about an hour

The solution does not require complex manipulations from you - just leave your smartphone on charge for literally a few hours. After this, it is recommended to hold down the power button for 10-15 seconds, as the system may not respond to normal startup attempts.

In my case, a completely dead Samsung Grand Prime smartphone had to hang on the charger for about an hour, after which it would come to life and charge. Therefore, this option should not be excluded.

Software failure

Important – this method only works if the smartphone suddenly turns off while fully/partially charged. Let’s use the “Hard Reset” of the Android system, which is present in any modern smartphone:

We switch the phone to “Recovery Mode”. For some models, the transition method differs; by default, you need to hold down the volume, power and “Home” buttons (middle on the bottom in the front model). To clarify the exact translation mechanism, you can use a search engine.
We hold the combination for up to 20 seconds, after which the device’s software menu appears.
We stop at the item “Reset all software data” (Wipe data/Factory reset).
Select the “Confirm” column (Yes - delete all user data).
After that, find the item “Reboot right now” (reboot system now).

After rebooting, the problem should disappear. It should be noted that all data will be erased, and there may also be problems with logging in due to an unknown Google account error.

3. Power supply failure

It sounds funny, but sometimes it is a broken socket that likes to fray the nerves of smartphone owners - try connecting the charger to another, after checking the functionality with other household appliances.

Another common case is damage to the USB cable or charger unit. Try changing your diet. Tug the cable bends, blow out the plugs and sockets.

Separately, check the capabilities of the power supply itself - milliampere data should be written on it. Perhaps your unit is not fast enough to start a smartphone/tablet. By the way, this is a very common problem on cheap Chinese devices.

Remove any debris, dust and dirt from the connectors

Battery fault

It is possible to check the battery condition only on devices with a removable cover - carefully remove it and take out the battery. We inspect it for the presence of swelling, obvious scratches, melted/burnt elements.

Be sure to check the battery health

If everything is fine, wipe it with a damp cloth, and also do not bypass the terminals (protruding contacts). They must be even, otherwise we do not recommend correcting anything yourself.

In the case of a non-removable battery, you need to use special applications - AccuBattery (checks the battery charge controller) and Battery. But they will be relevant after any activation.

Mechanical damage

There are several options:

The power button is broken/displaced, which makes it impossible to simply give a signal. Such a repair will cost you no more than $4, provided that the “original” button is preserved.
The socket for the USB cable is damaged - this may be the result of careless handling or sudden pulling out of the cable. Repairs also won’t cost a penny; you’ll spend around $6-12 (depending on the model).
“Battery death” is one of the most unpleasant options. Repairing the battery is obviously useless, and if you buy a new one, you sometimes have to wait up to a month for delivery.
The contacts inside the back cover are damaged - they are responsible for transmitting power to the elements of the mobile phone. In this case, it is difficult to estimate the cost of repairs; it all depends on the deplorable situation, model, and service center.

Reasons for blinking

The following types of screen flashing are possible:

fading and quickly turning on the screen;
flashing without turning off;
uneven illumination.

If such a problem occurs in the operation of the phone, an urgent solution is needed. To do this, you need to find the possible cause of the problem.

Screen damage. When flickering, this is the first thing that comes to mind. Dropping your phone can have more serious consequences than just cracks or scratches. Screen damage caused by a fall can be easily dealt with by a technician. Often the cause of display malfunction can be contact with moisture. This problem is solved by replacing the touch panel or the entire display.

Damage to the cable. The phone screen is connected by a thin cable to the motherboard. In modern compact phones, their cables are very thin. They are not damaged when dropped, but their malfunction is affected by the following reasons: manufacturing defects, water ingress, exposure to temperatures, and component disconnection. The exact cause can be determined by disassembling the smartphone. Whatever the reason is identified, the cable will have to be replaced.

Software malfunction. If there is constant flickering, there is a high probability of a software failure. Many users do not even realize that this may be causing the problem. To eliminate it, the device is checked for viruses, the settings are reset, or the operating system is reinstalled.

Battery damage. It affects the display of information on the display. With prolonged use, it becomes depleted, loses capacity and because of this, current does not flow to the motherboard for information processing. Replacing the battery will eliminate the cause of the flickering. When choosing, preference should be given to original batteries: cheap analogues will not last long.

Problems with video control. Information on the screen is displayed due to the operation of the graphics accelerator. It consists of a matrix, memory and binding, and if at least one of its elements fails, this will affect the operation of the display. The video accelerator is subject to overheating. If the cooling system does not cope with its task, the video chip will fail. The cause of flashing can even be a partial breakdown. The problem is solved by replacing the video chip.

Flashing while charging. Flashing may occur when the phone is connected to a charger. The reason may be that the smartphone is overheating. And because of this, the cable may fail. This often happens when using non-original devices. If there is such a problem, it is recommended to use a high-quality power supply.

Charged all night and didn't charge

Yes, this happens - all night your redmi (you can enter the name of the specific model yourself) lay “tied” to the charger. And the next morning, not only was it not charged, it was so discharged that it didn’t want to glow at all!

Most likely, the following happened:

The charger does not work;
The USB cord is damaged;
The phone connector is damaged.

Any of these reasons can lead to a complete discharge of the battery, so deep that even after eliminating the cause, you still will not be able to turn on the phone.

So, try connecting a new charger adapter or replacing the USB cable. If the battery charge is low, you need to keep the device on charge for about fifteen to thirty minutes, and only after that try to turn on the smartphone. Most likely, the device will boot successfully, but the battery level is unlikely to exceed 2-3 percent, and you will need to wait for the charging cycle to complete.

If replacing the charger or cord does not solve the problem, you should contact a service center to replace the connector on the phone. Resoldering a USB connector is a labor-intensive operation; it requires special equipment (a soldering station) and some experience in performing such work. Therefore, it is better to entrust this work to specialists.

Battery

Another possible problem is a weak and failing battery. This is usually true for smartphones whose battery has not been changed for more than 3-4 years. You can check this by putting your phone on charge.

If the display starts working correctly, it means that the cause of the problem has been found.

In this case, you need to purchase another battery and replace it. If the back cover of the phone does not open or the battery is built-in, it is recommended to contact a specialist. Be careful when choosing a battery, as counterfeits not only quickly fail, but can also harm your smartphone.
