Xiaomi Redmi 9 does not turn on: what to do

Let’s just say the “case history” is a little different, but the methods of “treatment” are similar.

What can happen

  • A fully charged phone quickly loses charge. for example, from 91 to 20%. And then immediately turns off. And then you can’t turn it on. The case fits the theme only partially. Obviously, if the smartphone does not hold a charge, then there is a problem with the battery, you need to change it, and then figure it out further.
  • The loading screen freezes and nothing can be done about it. This case fits the theme perfectly.
  • Xiaomi smartphone does not turn on, but it is charging.
  • The case is similar but slightly different: the phone does not turn on, the LED is on, but there is no image on the screen.

Causes

There are several reasons why all these malfunctions occur:

  • The operating system was updated, some files were loaded incorrectly. It is possible that errors have occurred. In general, the problem appeared due to an incorrect update.
  • There was a deep discharge of the smartphone. Here it is already individual: either because the battery is already old and weak, or because the owner of the phone did something with it that required a lot of energy at once. It happens that the user does not fully charge the Xiaomi smartphone. Therefore, the charge indicator gives incorrect information. not true. The phone “seems” that everything is in order with the battery. And there the level is very low.
  • Work of viruses. It happens that they get into the phone. You need to install an antivirus and check everything, but first you need to turn on the device.
  • Moisture on the contacts that ruined them.

In all these situations, you need to try one effective method.

Solution

Why the phone does not turn on: usually batteries are made in such a way that they “go into protection” when the charge is low. That is, the battery “sees” that there is little energy, and does not allow itself to be discharged to the end. Therefore, the first thing to do is connect the phone to the charger. You can take a more powerful memory. For example, up to 5 V with current limiting up to 350 mA.

The next step is to leave the mobile alone so that it lies down for a while, recharges.

Next, you need to hold down the volume button and the phone’s power button. Two options: either the volume up button or the volume down button.

The screen should light up. You need to select the item Reboot to system. “Reboot the system”. The phone will turn off. And must turn on.

There is another option. this is a factory reset. This is a good way to “zero” the mobile, make it “clean”. The only negative: everything will be deleted from memory. Photo, video and the like.

What to do if the Xiaomi smartphone does not turn on after the update?

But it also happens like this: the smartphone began to update, turned off and no longer turns on. What needs to be done in such cases will be discussed in the article.

3 ways to solve the problem

If Xiaomi does not turn on after the update, then you can alternately try 3 options for starting a mobile phone.

Method one: reboot

It happens that the described problem is solved by simply rebooting the smartphone. To force it, you need to press and hold the on / off button of the mobile phone for 7-10 seconds. If everything is done correctly, the gadget will respond with a short vibration signal and the reboot process will begin.

This method should be tried first. Often it helps to cope with the problem. At the same time, the algorithm of actions is very simple.

Method two: reboot from Service Recovery

difficult option. To enter the service menu, you need to simultaneously hold down the volume up button and turn off / on the smartphone. A service menu will appear on the screen, from which you need to reboot. turn off the gadget. After that, the mobile can be turned on immediately, if, of course, it works out.

Method three: flashing

The most difficult option that exists, but if you act step by step, everything should work out.

It happens that, due to errors or a weak battery, the phone cannot update properly. In this case, rebooting does not help. You need to do the following:

  • Log in from PC to Xiaomi official website and find the latest firmware suitable for your phone.
  • Fully charge your mobile.
  • Connect your computer and smartphone, select File Transfer. The menu item may have a slightly different name.
  • Move the installer file to the system folder.
  • Install Firmware.

So that there are no problems

In many cases, it is possible to “revive” a Xiaomi smartphone that has stopped turning on. But it is better to try to prevent a problem from occurring than to fix it later. And for this it is recommended:

Force restart Xiaomi Mi 9 SE

First, let’s look at several methods related to recovery through Recovery mode. It will be possible to get into it if the gadget is charged by more than 15%. At the same time, by connecting the charger, you can verify the integrity of the screen and the operability of the USB connector.

So, if the phone responded to the charging connection, displayed the process of replenishing the battery, then after reaching a suitable level, you can proceed to the following manipulations:

  • Simultaneously hold down the power and volume up buttons. Hold them like this until the phone starts to vibrate. The boot screen will appear and it will be followed by vibration, then the power button can be released. Important: sometimes the combination with the volume down button works, not the volume up button.
  • In the menu that opens, select the item “Reboot to system” (in some versions – “Reboot system now”).

The device should immediately go to reboot, followed by a regular download of Android. By the way, if the gadget is not charging, it is recommended to try other USB cables and chargers. It is possible that the problem lies precisely in them, and the phone is simply dead.

Reset to factory settings

After the actions described above, several options for the development of events are possible. In addition to the usual reboot and power on, the phone may turn off again or hang on the splash screen. You should not be too upset because of this, because the manipulations done helped to make sure that a number of important functions and systems are working.

Rebooting through Recovery is an option suitable for situations in which the firmware received minor failures that resolved themselves. If the violation in the operating system is much more serious (for example, after a firmware with errors), then you will have to perform a factory reset. It is important to consider: during such actions, all files are deleted from the device’s memory, including photos, videos and music.

The device should go to reboot. It can last much longer than usual (up to 10-15 minutes), after which you will have to perform the initial setup.

There are many reasons for the disruption of the stable operation of the device. often problems arise against the background of everyday use. According to the masters and representatives of device manufacturers, power-on failures can be associated with the following events:

  • after updating the operating system, any system files were installed with errors;
  • the device stopped loading due to viruses that got in with applications not installed from the Play Market;
  • after falling on a hard surface, the display or battery cable is disconnected;
  • the USB connector is clogged or small but harmful rust spots have appeared on the contacts due to moisture.

Immediately it is worth noting: to cope with mechanical damage on your own is not easy. During home repairs, you can inadvertently break any connections, thereby making the smartphone unrepairable. If the methods proposed below do not give a positive result, then it is recommended to contact a trusted SC for diagnostics and repair.

Additional Methods

What to do if the methods described above did not help? The gadget suddenly turned off, stopped responding to pressing the power button or charging. with a high probability the problem lies in mechanical damage. If earlier it fell or fell into the water, then it makes sense to contact a service center for diagnostics. Another likely cause is a battery failure. The main symptom is a fast discharge from 100 to 0 percent until a malfunction is detected. For smartphones with removable batteries, you can try to buy a similar one and simply replace it. If the case is solid, then it will not be possible to do without the intervention of masters.

Xiaomi Mi 9 turns off by itself

During the recovery of mobile phones, many cases have been identified. When Xiaomi Redmi Mi 9 turns off by itself. Of course, there is a normal explanation for everything. A smartphone is a device equipped with a processor, memory and other elements. Which require a significant amount of electrical energy to operate. The batteries used in the package are quite capacious, but they are very critical to various adverse factors:

  • long stay in a discharged state;
  • overheating in the sun or battery;
  • water damage;
  • internal short circuit and corny wear.

If you don’t understand how to do it, then look here Xiaomi mi5 turns off periodically.

Every year the source loses its capacity, so you should not count on an infinite charge. And the number of programs, on the contrary, is increasing. Among them, there are often incorrectly written ones that lead to banal harm. Given the above, we can distinguish the following reasons for the spontaneous shutdown of smartphones:

  • a worn out battery that needs to be replaced;
  • charge control malfunction, wizard service required;
  • using software that causes critical errors and the system reboots on its own.

If you replaced the battery, and the smartphone still turns off spontaneously, then at a different charge level. It is recommended to perform a full reset of the settings and memory. It will delete all data from the device, including those that cause critical errors. Also, along with them, personal data and everything that was stored on the system disk will disappear. This is done through the engineering menu or from the user menu, after backing up or transferring data.

On average, the battery lasts 2-3 years. Then it has a sharp drop in capacity, and unauthorized power outages can occur. If a critical error occurs, then a reboot occurs.

Spontaneous shutdown of the smartphone Xiaomi Redmi Mi 9

A smartphone is a technologically complex device consisting of many modules. Therefore, there may be several situations when Xiaomi Mi 9 turned off and does not turn on. Consider the most common causes and methods for eliminating the defect.

Depleted battery

This is the most common reason for this behavior of the device, because it contains a chemical battery in which irreversible processes take place. No matter how manufacturers praise their batteries, which do not have a memory effect and do not have leakage, all this is present. Plus, each source has a limit on the number of charge cycles. It is incorrect to consider a cycle when the battery is completely discharged and then recharged. It is correct to count all cycles, including when it is not completely discharged, since the chemical process still proceeds. If you regularly follow the cycle, that is, discharge the battery to 10% and charge it at rest, then it will last for a longer period services. In practice, this is far from being the case, because it is impossible to build up to a single schedule and strictly observe it. There are always deviations, and therefore exhaustion occurs much earlier than the stated period. The battery charges quickly and discharges instantly. The solution to the problem is to replace the battery.

Hardware failures

When switched on, the phone consumes the most power. This is especially well observed when the display is activated, as power consumption increases. If there is a breakdown in the LCD, power controller or other devices, then this behavior may be observed due to a short circuit or overheating.

  • “Dead Pixel Treatment”: The platform not only tests a mobile phone for dead pixels. And then “heals” them, but at the same time reveals other defects in the display.

When using applications, it is recommended that the device not be disconnected from the chargers for the duration of the “treatment”. During pixel processing, the smartphone is constantly on, so the charge may not be enough.

Screen microcracks are fraught with a break in the power circuit. If this happens, then you will have to change the screen. Fortunately, in China they are several times cheaper.

A banal method is to simply log into your account on the device. Click on the item “Delete Mi account” below.

In this case, the account will be unlinked from the mobile phone. There will no longer be a message when the machine is booting up.

If Xiaomi has lost sound, you should first check the audio settings. If there is an active mode (with sound), then we continue to look for the problem.

Necessary. clean the headphone jack.

If the headset icon is on the screen of the Xiaomi smartphone, and the headphones are not connected, it means that the contacts are shorted. Therefore, the sound is transmitted to the headphones, even though they are not physically connected.

Reboot your phone after cleaning.

If during a call the interlocutor does not hear you well, then this function may be disabled. Go to the “sound and vibration” settings and move the “noise reduction” slider to the value “on”.

If it is activated, and there is crackling and noise during the conversation, then try turning off the function.

The built-in mobile assistant can also interfere with the normal operation of the microphone. Go to the settings menu. search Google. Next, turn off the voice finder feature. Restart your Xiaomi phone.

How to talk to Xiaomi technical support.

Go to your mail service type and log in.

Click create message. In the first line, we write this address: mishu@Xiaomi.com Or this one: service.us@Xiaomi.com You can write in the subject (Unlock mi account). You must write in English. Use an online translator.

Next, we write what is required. I want to reset my Mi account on Xiaomi Redmi 6a. This procedure is long and may take 2-3 weeks.

Choose English and any country;

We make an Internet connection using Wi-Fi or cellular data;

We go to ” Privacy Policy” (Security Policy) and select any piece of text. On the right, click on the three dots, “Web Search” and “Google App”. Next, we can go to the settings by clicking on the “Settings” entry. We are looking for the item “About Phone” and click on it.

After logging in, click on “Software version (Miui version)”, which you need to quickly click a few (about 5) times until a notification appears about granting “Developer rights”. We go back and go to “Second Space”, and then “Turn on second space”.

Here a second space is created and the device is already quite ready for work. Nevertheless, after the reboot, everything will be reset and you will have to do everything again, so we continue. We go into the settings, then “About Phone”, “Additional Settings” and “Developer Menu (Developer)”. Move switch USB Debugging to the enable position.

We connect to the computer using USB and start Switch. Download “Minimal Adb and Fastboot” and turn it on. We go to the first desktop, and on the computer we type “adb devices”. Here we enter the following command: adb (introductory command) shell pm uninstall (parameters).k.user 0 (values) com.Xiaomi.finddevice (server connection);

Delete “Find my phone (Find my phone)”.

Nuances after such a decoupling.

After that, the gadget is ready for full operation: you can go online, use various programs, etc.

However, it is worth noting that it will not be possible to use Xiaomi services. Which is explained by the absence of the account itself. There are a lot of complaints about the Xiaomi account from users due to poorly executed software, and it is quite logical that it is deleted.

If the smartphone was in a humid room, or moisture got on it. This is especially true of the USB input, and leakage into the smartphone. Oxides can lead to current leakage, and this contributes to the heating of the device. To fix, you need to clean the USB. Take a thin stick and wrap cotton wool around it. Dip it in white spirit or alcohol, and wipe the contacts at the entrance.

If water got inside, then you need to disassemble Meizu. And, carry out the same operation with contacts that are attached to the board. But, before doing this, disconnect the battery cable to avoid a short circuit.

If Meizu M8 does not have a microphone, for this you need to do the following.

Open the security settings, look for root access and click accept, reboot the device. Open the “phone” and enter this combination ##54298## or ##3646633##. Scroll to the right and find ” Hardware Testing “. audio. Audio Playback set the value of Heaset PGA to 160. Exit the menu and reboot the phone.

Also, software methods can be used. But, they can only help if there are no malfunctions in the device itself. This method is one of the simplest, we open the settings on the mobile phone. And, select the command “reset settings”. Keep in mind that this means deleting all data from the smartphone.

So that the stripes on the Meizu M8 screen do not bother you, you need to:

  • Make sure the integrity and reconnect the display module cable;
  • Replace the screen completely if there is real damage;
  • Update firmware and Flyme shell.

In the first situation, contact could simply be broken. The connection came off due to impact, the contacts are clogged or the display was not fully connected at the factory.

  • Select “About phone”
  • In the submenu, you will need to select check for updates. when you turn on Wi-Fi, everything will start downloading;
  • The device will reboot.

The appearance of stripes during use can be eliminated immediately after purchase by updating. This will not void the warranty. Unlike a complete flashing or self-repair in the same period.

A banal method is to simply log into your account on the device. Click on the item “Delete Mi account” below.

In this case, the account will be unlinked from the mobile phone. There will no longer be a message when the machine is booting up.

If Xiaomi has lost sound, you should first check the audio settings. If there is an active mode (with sound), then we continue to look for the problem.

Necessary. clean the headphone jack.

If the headset icon is on the screen of the Xiaomi smartphone, and the headphones are not connected, it means that the contacts are shorted. Therefore, the sound is transmitted to the headphones, even though they are not physically connected.

Reboot your phone after cleaning.

If during a call the interlocutor does not hear you well, then this function may be disabled. Go to the “sound and vibration” settings and move the “noise reduction” slider to the value “on”.

If it is activated, and there is crackling and noise during the conversation, then try turning off the function.

The built-in mobile assistant can also interfere with the normal operation of the microphone. Go to the settings menu. search Google. Next, turn off the voice finder feature. Restart your Xiaomi phone.

You can reset your account using Xiaomi support.

To do this, you must have documents on the phone. to confirm that it is not stolen.

Click create message. In the first line, we write this address: mishu@Xiaomi.com Or this one: service.us@Xiaomi.com You can write in the subject (Unlock mi account). You must write in English. Use an online translator.

Next, we write what is required. I want to reset my Mi account on Xiaomi Redmi 6a. This procedure is long and may take 2-3 weeks.

Choose English and any country;

We make an Internet connection using Wi-Fi or cellular data;

We go to ” Privacy Policy” (Security Policy) and select any piece of text. On the right, click on the three dots, “Web Search” and “Google App”. Next, we can go to the settings by clicking on the “Settings” entry. We are looking for the item “About Phone” and click on it.

After logging in, click on “Software version (Miui version)”, which you need to quickly click a few (about 5) times until a notification appears about granting “Developer rights”. We go back and go to “Second Space”, and then “Turn on second space”.

Here a second space is created and the device is already quite ready for work. Nevertheless, after the reboot, everything will be reset and you will have to do everything again, so we continue. We go into the settings, then “About Phone”, “Additional Settings” and “Developer Menu (Developer)”. Move switch USB Debugging to the enable position.

We connect to the computer using USB and start Switch. Download “Minimal Adb and Fastboot” and turn it on. We go to the first desktop, and on the computer we type “adb devices”. Here we enter the following command: adb (introductory command) shell pm uninstall (parameters).k.user 0 (values) com.Xiaomi.finddevice (server connection);

Delete “Find my phone (Find my phone)”.

Nuances after such a decoupling.

After that, the gadget is ready for full operation: you can go online, use various programs, etc.

However, it is worth noting that it will not be possible to use Xiaomi services. Which is explained by the absence of the account itself. There are a lot of complaints about the Xiaomi account from users due to poorly executed software, and it is quite logical that it is deleted.

Reset to factory settings

After the actions described above, several options for the development of events are possible. In addition to the usual reboot and power on, the phone may turn off again or hang on the splash screen. You should not be too upset because of this, because the manipulations done helped to make sure that a number of important functions and systems are working.

Rebooting through Recovery is an option suitable for situations in which the firmware received minor failures that resolved themselves. If the violation in the operating system is much more serious (for example, after a firmware with errors), then you will have to perform a factory reset. It is important to consider: during such actions, all files are deleted from the device’s memory, including photos, videos and music.

The device should go to reboot. It can last much longer than usual (up to 10-15 minutes), after which you will have to perform the initial setup.

Force restart Xiaomi Redmi 9

First, let’s look at several methods related to recovery through Recovery mode. It will be possible to get into it if the gadget is charged by more than 15%. At the same time, by connecting the charger, you can verify the integrity of the screen and the operability of the USB connector.

So, if the phone responded to the charging connection, displayed the process of replenishing the battery, then after reaching a suitable level, you can proceed to the following manipulations:

  • Simultaneously hold down the power and volume up buttons. Hold them like this until the phone starts to vibrate. The boot screen will appear and it will be followed by vibration, then the power button can be released. Important: sometimes the combination with the volume down button works, not the volume up button.
  • In the menu that opens, select the item “Reboot to system” (in some versions – “Reboot system now”).

The device should immediately go to reboot, followed by a regular download of Android. By the way, if the gadget is not charging, it is recommended to try other USB cables and chargers. It is possible that the problem lies precisely in them, and the phone is simply dead.

There are many reasons for the disruption of the stable operation of the device. often problems arise against the background of everyday use. According to the masters and representatives of device manufacturers, power-on failures can be associated with the following events:

  • after updating the operating system, any system files were installed with errors;
  • the device stopped loading due to viruses that got in with applications not installed from the Play Market;
  • after falling on a hard surface, the display or battery cable is disconnected;
  • the USB connector is clogged or small but harmful rust spots have appeared on the contacts due to moisture.

Immediately it is worth noting: to cope with mechanical damage on your own is not easy. During home repairs, you can inadvertently break any connections, thereby making the smartphone unrepairable. If the methods proposed below do not give a positive result, then it is recommended to contact a trusted SC for diagnostics and repair.

Additional Methods

What to do if the methods described above did not help? The gadget suddenly turned off, stopped responding to pressing the power button or charging. with a high probability the problem lies in mechanical damage. If earlier it fell or fell into the water, then it makes sense to contact a service center for diagnostics. Another likely cause is a battery failure. The main symptom is a fast discharge from 100 to 0 percent until a malfunction is detected. For smartphones with removable batteries, you can try to buy a similar one and simply replace it. If the case is solid, then it will not be possible to do without the intervention of masters.

All problems with Xiaomi Redmi 9 and their solutions

Redmi 9 is one of the cheapest Xiaomi phones that we can find on portals like Amazon, around 140 euros. But because it’s cheaper, that doesn’t mean it has to have more or less problems than more expensive smartphones. On our site, we constantly see how no mobile phone on the market can avoid problems of various types. For this reason, we are going to take a look at the most common problems faced by Redmi 9 and their possible solutions.

It is not necessary to reach too high a price level to find balanced and complete options such as Redmi 9. The hardware requirements of each mobile phone can be very different, and therefore problems can manifest themselves in different ways, despite the fact that the count is made by the same topic. same. operating system or even processor. In the case of Redmi 9 just updated to MIUI 12 and Android 10, no matter how modest it is, Xiaomi chose it to update to Android 11.

Faults and problems on Redmi 9

Many of the users reporting problems with Redmi 9 go to Xiaomi’s official forums to try and get support from other owners of the device. So let’s take a look at all these problems and the solutions that worked best.

Screen does not rotate

One of the issues with the Redmi 9 is the ability to rotate the screen when opening apps. This issue requires the mobile phone to be restarted periodically so that it can be used horizontally.

Solution: Solution in this case. delete System Launcher cache. which can be found in Settings / Applications. In addition, we will also have to clear the cache of the affected games or applications and restart the mobile. Finally, if all else fails, we can use the screen rotation tool.

Performance Issues

Redmi 9. a modest terminal in terms of hardware. A more modest option, that is, with 3GB of RAM and 32GB of internal memory, may experience performance problems. A user experiencing these issues notices general sluggishness throughout the system, such as when opening applications or playing certain games. The problem is that the terminal can quickly run out of internal memory or RAM resources to run applications in the background.

Solution: In this case, the solution is to keep the terminal as up to date as possible. That is, we will have to free memory, remove unnecessary applications, close background tasks to free up RAM, and reboot the device at least once a day to free up the cache. Thus, we will notice an improvement in performance, while not neglecting the available internal memory and applications open in the background.

Problem with non-activated SIM card

Some Redmi 9 users have reported that the SIM card activation is not working properly. However, the solution is applied in a simple way and is typical for many other terminals.

Solutions: Click the notification that appears in the top bar. A confirmation message will be sent to register the SIM card. If it doesn’t work, restart your mobile and repeat the process.

Touch screen problem

While it shouldn’t be a common occurrence, some users experience touchscreen issues right after the device’s release. In some cases, when you turn on the terminal for the first time, Redmi 9 does not respond and it is not possible to go to the first configuration screen. In this case, we find two possible solutions:

  • remove the plastic from the screen and the original protector. In addition, we will remove any third-party cases or protective devices that we may have put on prior to the release of the mobile phone.
  • save the power button hold for at least 10 seconds until the mobile phone reboots. When you turn on the mobile touch, it will work correctly.

Problems with whatsapp

This issue is related to photos taken on WhatsApp. When viewed in the gallery, they sometimes look crooked and have an odd color.

Solution: Go to Settings / Applications / WhatsApp and clear the application cache. Make sure that no filter is activated in WhatsApp. We then restarted mobile and the problem should have gone away.

Problem with “Raise to Wake”

Many users have reported that the mobile screen turns on by itself when moved. This makes the battery drain faster and there are users looking for a solution. Actually this is not a problem, but sometimes this function does not work correctly.

Solution: We will have to enter the lock screen settings and disable the “Raise to Activate” feature. The problem is that many users have it disabled and the same thing keeps happening. Therefore, we must activate the function again, confirm and deactivate it again. Then we restart the mobile and check if the problem has disappeared.

Xiaomi Mi 9T Pro won’t charge or turn on

There are many reasons why Xiaomi won’t turn on or charge. Most often, a malfunction of a actively used device is the result of a broken charging connector due to heavy use. As a rule, the part cannot be repaired, but immediately requires replacement with a new component.

Xiaomi does not charge most often for the following reasons:

a large amount of moisture got into the device, which negatively affected the operation of the connectors; periodic mechanical damage leads to deformation of the nest. As a result, the plug enters the connector with an offset, or it cannot be inserted at all; bent contact pads; dirt or dust has entered; when foreign objects get in, damage occurs to fragile parts that cannot be restored; assembly defect.

If the Xiaomi phone does not charge, do not rush and immediately proceed to disassembly. It is recommended to carry out self-diagnosis beforehand. It is important to note that a connector malfunction is rarely agreed to be fixed under warranty. In practice, most often, specialists establish mechanical damage and other causes associated with improper operation of the device.

The charging socket can break for many reasons. First of all, it is worth remembering whether the phone fell or received serious blows that could cause damage. Malfunctions can also occur if the cord is pulled abruptly from the device. If Xiaomi Mi 9T Pro does not turn on and does not charge, it is first recommended to carry out a number of diagnostic measures:

inspect the phone for integrity, try to connect using a USB cable to a computer or other power supply. If charging has started, then the problem is a malfunction of the adapter; if possible, disassemble the phone, remove the battery, wipe all contacts and outputs. Inspect for faulty contacts. Next, you need to assemble the phone back and check the charging operation again; conduct an external inspection of the connector for broken or bent contacts, possible ingress of third-party objects or a large amount of moisture.

If a malfunction was detected during the verification process, in this case, you can proceed to the preparatory measures for repair.

Any replacement or repair or technique is not possible without the use of special tools, so it is recommended to prepare the following:

a set with screwdrivers or one Phillips; scalpel for stripping the remaining glue from the wires; tweezers for fixing wires; soldering iron with solder; plastic spatula; glasses for magnification.

To make it more convenient to work, you can use an additional holder for a fragile motherboard.

Xiaomi Charging Connector Replacement

If Xiaomi does not turn on and does not charge, you can proceed to the following replacement instructions:

How to Fix Xiaomi Mi 9 Won’t Turn On #Shorts

remove the SIM card tray. Using a screwdriver, unscrew the screws located on the sides of the power connector; move on to removing the back cover of the case. In order not to cause serious mechanical damage to the cable and buttons, perform this action with the utmost care and use a plastic spatula as a tool. Since the fingerprint sensor is on the surface of the screen, the back cover can be removed easily; disconnect the cable from the battery; in the lower part of the case there is an additional board for the system connector, microphone and antenna, covered with a special overlay for the speaker; the additional board is removed by unscrewing the screws that fix the speaker module. Use a Phillips screwdriver as a tool; disconnect the board-to-board cable and antenna cable. Take tweezers and pull out the board; put a new connector and fix it with plastic latches. It is important to ensure that the connector is installed without changing the angle or inclination; reconnect the battery cable; check the operation of the connector. To do this, just connect the phone to the charger and check if the indicator appears; since the adhesive around the entire perimeter of the smartphone is not reusable, you need to take a scalpel or other metal object to clean it, and then apply a new composition. This will create a tight structure; reassemble in reverse order.

Once the device is fully assembled, it is recommended to re-work by plugging in the USB power cord. Also, after reassembly, it is worth checking the normal operation of the speaker and microphone.

What to do if urgent repair of Xiaomi Mi 9T Pro is not possible

Sometimes there are situations when a person does not have enough time to immediately carry out repairs. In this case, there is a temporary solution to the current situation. The process is to find the optimal position of the USB wire, in which the failed contacts will start charging the battery.

The procedure is performed in the following sequence: the plug is inserted into the broken socket, and the adapter must be connected to the power supply; press the smartphone with a heavy book or other objects to fix its position; gradually and smoothly move the plug until the charging indicator appears. It is important to perform all actions gradually so as not to cause even more damage or short circuit contacts; as soon as the position is found, it remains to fix the wire in this position with a heavy object.

However, such a solution is only a temporary way out. In order not to harm the further operation of the device, it is recommended to replace it as soon as possible.

If the device has a removable battery, then you can use a universal charger, but its cost is an order of magnitude higher and it is not suitable for cast phones. Therefore, an alternative option can not be used in every case. The failure of the charging connector is a fairly common problem of modern smartphones and not only from the manufacturer Xiaomi. This is due to the fragile design of this element, therefore, with careless handling, it becomes unusable. You can replace it yourself, just follow the instructions above.
