Why Xiaomi Redmi Note 3 Pro stopped charging

How to turn on your Xiaomi phone

There are several ways to turn on your Xiaomi smartphone. Some of them work if the power button is not functioning for some reason. Let's look at the most useful options.

How to turn on a Xiaomi phone, including without a power button:

1. Power button. The first and most obvious method. Just hold down the power button for a few seconds. The device will vibrate and downloading will begin. Provided that everything is in order with the firmware and hardware of the phone. Sometimes it seems that the Xiaomi phone has stopped turning on, although the power button simply does not work. The device simply does not respond to the power button if, for example, the cable has come loose from it.
2. Connecting the charger. Another available method: you need to connect the charger and plug it into an outlet. The smartphone will come to life and start loading. This method will help if the smartphone does not boot due to a dead battery.
3. Reboot from recovery (if the phone's power button works). Press the Power and Volume Up buttons at the same time. In the stock recovery menu, select Reboot to System. Confirm the action with the Reboot button.
4. Removing the memory card. Sometimes a full external drive can prevent your smartphone from starting. Remove the microSD card and start your phone again. If the problem is a flash drive, this method will help.
5. Reverse the battery. This term in certain circles refers to the procedure of disconnecting the battery cable and then returning it to its place. When phones had removable batteries, everything was simpler. Now you have to disassemble the smartphone and remove the back cover. It's better to contact the service.

These are simple inclusion options, but sometimes even they don’t work and you have to resort to more serious measures. They will be discussed below.

If none of the activation options worked, it is obvious that the problem is much more serious and is related to the hardware of the smartphone. For example, if it fell on the floor or into water. You should not try to fix the phone yourself - this is fraught with even more serious problems. It's worth contacting the service.

First days of operation

Xiaomi smartphones sometimes do not charge in the first days of use. One of the reasons is that the device is very discharged. Wait a few minutes and the red indicator will light up; it also requires energy, which the battery simply does not have.

Charging hasn't started? Use simple tips:

• connect only to the original charger;
• when replacing the charger with an analogue one, check the parameters: 2 amperes and 5 volts;
• follow the sequence - first connect the cable to the power supply, only then plug it into the outlet;
• When charging from a PC, insert the cable into the USB on the rear panel. If there are version 3 ports (blue), use them.

What does the blinking color of the indicator mean?

Xiaomi models with LED indicators indicate a problem by the color of the diode. The frequency of flashing and the color of the signal (red, white, blue) can indicate the type of problem.

LED indicator signals when Xiaomi phone does not turn on:

• The red indicator is flashing , which indicates mechanical damage: the power button cable has come off, the battery has completely died, or the memory with the bootloader sector has been destroyed as a result of mechanical damage. In this case, it is possible that Xiaomi does not turn on and does not charge due to the condition of the battery.
• The white indicator flashes when the battery is deeply discharged. If the phone turns off, does not turn on and the white light blinks, then the battery charge is completely used up. You need to connect the charger and wait until it is fully charged. Only after this can the smartphone be turned on. A common situation after the battery is completely discharged.
• Blinking blue when you try to turn on the smartphone indicates a software problem: a crooked OTA update was installed, the bootloader crashed, or the MIUI system files were significantly damaged. Sometimes even after a regular phone update, it does not turn on.

If the problem is software in nature, you can fix it yourself. A hardware problem will require the intervention of a Xiaomi equipment repair specialist.

Only early Xiaomi phones (eg Redmi 4X) have LED indicators. The company does not install such indicators in newer smartphones. If you have a new smartphone, you will have to take Xiaomi to a service center for diagnostics. But first, you can try to solve the problem using the software methods described below.

Charger failure

Similar reasons can lead to failure of the charging connector itself. The consequence of this is the supply of current, the voltage and strength of which differ from the required values. As a result, the chip responsible for controlling energy transfer uses a red light to indicate the undesirability of using a faulty memory. Otherwise, there is a possibility of significant damage to the battery or even the smartphone.

This version is checked as follows: you need to find a similar memory and connect the device to it. If the red LED remains illuminated, then the cause should be looked for elsewhere. If the phone starts charging normally, just use a working charger.

The version with a cable fault is checked in the same way.

Reason #1: software glitch

Sometimes it happens that a smartphone’s firmware (stock or custom) fails. This may be due to viruses, incorrectly set superuser rights, and other reasons. The phone may turn off and not turn on. However, this problem can be solved.

Hard Reset will help - resetting the phone to factory settings: step-by-step instructions for hardsetting Xiaomi. In this case , all user data on the internal storage will be deleted . This applies to both photos, videos or music, and applications along with their settings. In fact, the phone will have to be configured again.

The link above contains several reset methods, but here is the easiest one for a switched off smartphone:

1. Hold down the Power and Volume Up buttons.
2. The phone will enter recovery mode, select Wipe Data.
3. Tap on Wipe All Data.
4. Confirm the action by clicking Confirm.

Once the process is complete, return to the main menu, select Reboot and Reboot to System to exit recovery mode and boot into MIUI.

The first boot after a factory reset may take up to 10 minutes. You cannot turn off your phone at this time.

There is a high probability that after the reset you will be able to start the phone and use it as normal. This method can help if the smartphone is functioning, but the screen does not turn on.

If Xiaomi does not turn on after resetting the settings, try the following methods to revive your smartphone.

Main reasons

The main reasons why a phone may stop charging could be some kind of mechanical failure or systematic mishandling of the device. But there is no need to panic - in many situations it is quite possible to fix the breakdown yourself. Among the main causes of the problem are the following:

1. Debris gets into the charging hole. Most users carry their smartphone with them even without a special protective case. As a result, debris, grains of sand and other small elements may get inside the charging hole. Therefore, if you encounter a problem with charging, it is recommended to use a can of compressed air to blow out the hole. It also doesn't hurt to clean it. The bristles of a toothbrush are suitable for this. When the procedure is completed, you can try to connect the charger to the appropriate port again.

1. The USB ports have become oxidized. If you use your phone in humid conditions, then there is likely a risk of oxidation of the charging port. This risk sometimes exists even with smartphones used in normal humidity. Therefore, it is recommended for anyone whose Xiaomi smartphone has stopped charging normally to check for such a problem. To do this, first turn off the mobile device so that it does not short-circuit, and then clean the socket with a needle dipped in alcohol. We do not recommend overdoing it with alcohol so as not to harm your mobile device.
2. The USB cord is broken. There is a possibility that the problem is not with the connector through which charging is performed, but with the USB cord. You can check the correctness of its operation using special technical equipment or experimentally by connecting it to another device. If charging proceeds normally, then the problem is not in the cord at all, but in the device. And on the contrary, if another mobile gadget will not charge via the same cable, then the problem is precisely the latter.
3. Software glitch. In some cases, charging may not occur correctly due to irregularities in the phone's software settings. They can arise simply due to prolonged use of the smartphone. A full reset to factory settings should help solve the problem.

1. Battery problems. It is known that Xiaomi batteries are among the most capacious among all gadgets known today. But even they can fail over time. Any battery has a certain number of charge cycles during which it functions. When they run out, it's time to change the battery.
2. Surely you know that the Android system collects information about smartphone charging. If the battery is systematically depleted to minimum levels, the charge controller may fail. Reset your settings to factory defaults and you will no longer have to deal with this problem. Just be careful: resetting will automatically delete all data from the phone, including photos, videos, contacts and other important information. Therefore, make a backup of your data first, transferring it to an alternative medium - a computer or flash drive. You can also save them to a cloud service and immediately download them back to your phone after resetting the data.

If you notice that charging is no longer happening as before, and the red indicator is blinking every now and then, then first we recommend removing the battery and soon inserting it back to check if any contact has come loose. It may come off for no apparent reason or due to accidental mechanical impact. If, after you inserted the battery back, the charging problem persists, then most likely the problem is something else.

You can also visually check if everything is okay with the battery itself. Thickening, smudges and other signs of aging may appear on the surface. If you notice them, immediately take the gadget to a service center.

Reason #2: Damage to firmware files

If the operating system files are damaged, then there is only one way out - to flash the smartphone again. If we are talking about stock MIUI, you will need the MiFlash Pro program and a set of ADB drivers.

If you have custom firmware installed, then it has its own instructions: the firmware is installed using TWRP recovery and firmware previously downloaded to the memory card in ZIP format. After the firmware is installed, you will need to set up your account and everything else again. You can download the firmware for your Xiaomi phone from the official updates catalog.

If you flash MIUI via MiFlash Pro, then it is possible to save user data. To do this, at a certain stage you need to check not the clear all and flash item, but save user data. Otherwise, all photos and music will be deleted without the possibility of recovery.

By the way, it happens that after flashing the firmware the phone freezes on the splash screen.

Rare causes of malfunction

• The memory card is full, and therefore the download is blocked quite quickly.
• The software installation occurred when the battery level was low. This led to a software error, as a result of which the phone simply does not start.
• Examine the SIM card carefully; sometimes a thin oxide film forms on it, which subsequently shorts the contacts. This phenomenon leads to incorrect operation of the device.
• The USB port cable broke off from the socket.
• You decided to get root rights, as a result of which a system battle occurred.

Finally, it is worth noting that work should not be carried out without training and experience. Every year phones improve, and therefore their design becomes much more complicated. If you start disassembling the device, then most likely you will only break the device.

Reason #3: Xiaomi bootloader corruption

Bootloader in Xiaomi is designed to boot your device securely. If it is damaged, the phone will not turn on. There can be many reasons for damage: a crooked OTA, an incorrectly performed root, or a failure.

You can return the bootloader to its place in several ways: flash stock MIUI using MiFlash Pro or restore the bootloader using a computer, USB cable and ADB/Fastboot.

You can also use the Xiaomi ADB/Fastboot Tools app.

Attention! Before restoring the bootloader using ADB/Fastboot, you need to make sure that all the necessary drivers for the smartphone are installed on your PC. Also check the cable connection. If the connection is accidentally interrupted during the process, you will receive a brick that can only be restored at a service center.

When should you go to a service center?

If replacing the cable and charger did not give anything and the Xiaomi Redmi smartphone does not turn on either in normal mode or in Recovery mode, you will still have to drag it to a service center. There they will conduct a full diagnosis of the device and render their verdict. Among the common hardware problems, I can name such a common occurrence as damage to the cable with the power connector. It burns out itself or the power connector and the smartphone does not charge. The cost of the train itself is several hundred rubles. Replacing it is not so difficult, but if you have no experience, it is better to contact professionals.

Reason #4: hardware problems

All of the above methods are only suitable if it is possible to enter recovery or at least Fastboot mode. But if the phone shows no signs of life at all, all the methods discussed are useless.

There is a problem with the hardware components; it is not recommended to try to open the phone yourself. This matter requires experience and you will have to take your smartphone to a service center. It is better to choose official intermediaries. Their price is a little higher, but the repairs are of better quality.

If your Xiaomi smartphone is still under warranty, then all the more you need to contact the official service center. To do this, you will need a smartphone box, a receipt confirming the purchase of the product, a warranty card and a passport.

If your Xiaomi smartphone does not turn on, in most cases you can solve the problem yourself. But not when the phone's hardware components are damaged. In this case, repairing your smartphone at a service center will fix the problem.
