Smartphones manufactured by Xiaomi are rightfully considered the most trouble-free of Chinese-made devices. Still, even they sometimes - very rarely, but still demonstrate a stubborn desire not to turn on, hang up and upset their master. Be calm like a lotus flower even if Xiaomi does not turn on for an unknown reason! Most of the cases described below will solve the problem without contacting service center.
Charged all night and didn't charge
Yes, it happens - all night long your redmi (name specific model you can substitute yourself) lay "tied" to the charger. And in the morning he, not only was not charged - he was discharged so much that he did not want to at least somehow glow!
Most likely, the following happened:
- The charger does not work;
- Damaged USB cable;
- Phone connector damaged.
Any of these reasons can lead to a complete discharge of the battery, so deep that even if the cause is eliminated, you still cannot turn on the phone.
So, try plugging in a new charger adapter or replacing the USB cable. If the battery charge “went”, 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 need to wait until the end of the charge cycle.
If replacing the charger or cord did not solve the problem, you should contact the service center to replace the connector on the phone. Soldering a USB connector is a laborious operation, it requires special equipment (soldering station) and some production experience similar works. Therefore, it is better to entrust this work to specialists.
Flashing red indicator
On your Xiaomi, the red indicator flashes and the device does not turn on. The situation is sad, but solvable. True, in this case, you will also have to visit the service center.
A flashing red diode, and an absolutely unresponsive device is a possible sign of a faulty power button, a cable falling out on motherboard as a result of mechanical impact (fall or impact) or failure of the power controller itself.
In any case, the specialists of the service center should have experience in repairing such damage.
Please note: if you try to disassemble the device yourself, you can lose the warranty.
Software failure
If your mi smartphone managed to “freeze” when the screen is inactive and does not want to turn off at all, you can pull out the battery for a while. Everything would be fine, but most new phone models have a non-removable battery. In this case, a long one will help - more than 10 seconds. pressing the "Power" key (turn on).
If the firmware is in order, the smartphone will vibrate habitually, then the operating system will start.
Usually, a software failure occurs due to an inept self-flashing of the Android version, twrp installs, as well as other similar user actions.
Another option for a software failure after an unsuccessful update is to simultaneously hold down the volume down (“down”) key and the power button on the switched off phone.
If you have purchased a smartphone Xiaomi Redmi 4 then done absolutely right choice, since the given mobile device it is quite inexpensive and at the same time it has excellent performance characteristics. In terms of price and quality, the company's products xiaomi consistently occupies a leading position in the market.
Most importantly, there are no complaints about the quality of gadgets from this manufacturer. Although, of course, violations and failures cannot be avoided, because the technique cannot be perfect. Some users are facing the following issue: Xiaomi phone Redmi 4 won't turn on and it's not entirely clear why it can't boot.
What to do in such a situation? First of all, you should find out if the warranty on the device is still valid. If yes, then take it to the official service center so that the masters fix the problem. It is especially important to do this if Xiaomi Redmi turned off and does not boot almost immediately after purchase. It is possible that you got a defective model, and it should be replaced.
The situation becomes a little more complicated if you purchased the device on the "black" market in pursuit of a low price, or the purchase was made from an official representative of the manufacturer, but the warranty period has already expired. Then you will have to figure out on your own why the smartphone does not start, and fix the breakdown. Without being a specialist, you are unlikely to be able to do this with an absolute guarantee, but you can try to check the gadget for the most common problems.
In today's article, we will tell you what to do if Redmi 4 does not turn on, as well as consider the main possible reasons this phenomenon. Recommendations in this material, relevant for other smartphone models xiaomi due to the identity of their operating systems.
Why the phone may not turn on
Among the main reasons why the phone does not turn on are the following:
- Violations in the firmware.
- Moisture getting inside the mobile device with subsequent oxidation of the contacts or breakage of the service board.
- Problems with the power button or bottom cable.
- Damaged battery or charging socket.
- A software failure that can be fixed by rebooting the smartphone.
- Mechanical damage resulting from the fall of the gadget or other strong contact with something.
- Short-term problems associated with sudden changes in ambient temperature.
If the phone stops booting, first of all, pay attention to the circumstances under which this happened for the first time. If mechanical damage has occurred, you can not do without going to a specialist to replace the damaged part. The same applies to the situation with moisture getting inside the gadget or problems with the power button.
On your own, you can only eliminate a malfunction in the firmware or some situational problems with individual applications. Moreover, you do not even have to find out the specific reason why the smartphone turned off and does not work. It is quite possible that general measures aimed at normalizing the operation of the system will suffice.
For example, very often users, not knowing how to enable mobile phone are used in two popular ways.
Reset to factory settings
This procedure is also called hard reset. It is suitable if the smartphone does not turn off constantly, but periodically, or at least can be loaded in recovery mode.
You should start in recovery mode by holding down the power and volume down buttons at the same time. In this position, we hold them exactly until the Mi logo appears on the screen. After that, we can release the power button, although we continue to keep our finger on the volume control. Once in the recovery menu in this way, select English language interface, after which we look for the item hard reset. By clicking on it, we confirm the intention to reset all data to factory settings.
At this method there is one significant disadvantage: during the procedure, absolutely all data is deleted from the smartphone, including the user's personal files and even his contact list. Therefore, we recommend that you first make a backup so as not to lose personal information, and remove the memory card.
Smartphone flashing
Problems with software, which culminated in the shutdown of the mobile device, can also be solved by changing the current firmware version. The procedure is similar to the previous one, but it involves an additional step in the form of a preliminary download from the Internet of the firmware version you need. We recommend downloading firmware only from trusted sites or thematic forums, after making sure that they are suitable for your smartphone model.
By downloading the update operating system, we load the smartphone in recovery mode in the same way as described above. We connect the gadget to the computer via a USB cable. Next, you need a program designed to install firmware and other program files on the company's smartphones xiaomi. We launch it and wait until the connected device is detected. It remains to specify the path to the firmware file and click on Flash, which corresponds to the beginning of the installation procedure.
When you have to go to the masters
If the methods described above did not help and Xiaomi Redmi did not turn on, be sure to plan a trip to the service center to the specialists. You will also have to go to them in situations where:
- The device does not show any signs of life at all and does not even boot in recovery mode;
- The smartphone does not boot, and at the same time the light starts flashing red;
- The system freezes at the stage of loading the Mi logo;
- There is a serious mechanical damage to the phone, requiring the replacement of any parts.
We strongly advise you not to even try to fix a serious problem in the operation of your smartphone yourself. Chances are you will only make the situation worse. In fact, you can only try to restart your mobile device, as well as reset it to factory settings or change the firmware. If all these measures did not help, you should immediately go to the masters. Believe me, it is better to immediately contact a specialist than to exacerbate the problem on your own and end up paying even more money for repairs.

Xiaomi electric scooters are different high quality assembly and excellent technical specifications. Most models, provided they are properly used, function without any problems for 5 years or more. However, in some cases, riders may encounter a problem when the Xiaomi electric scooter does not turn on or does not charge.
The article contains the most common problems, due to which it becomes impossible to turn on the device and recharge the battery.
Device Diagnostics
First of all, you need to reboot the controller, in 50% of cases this fixes the problem. If a this decision did not help, then for further self-diagnosis, you will need to use a voltmeter.
Conventionally, the internal filling of the unit can be divided into 4 parts:
- Control block;
- Controller;
- Battery protection board (BMS - Battery Monitoring System);
- Accumulator battery.
Initially, the voltage at point "A" is measured. If it is normal, then the problem must be sought in the controller or control unit. Identification of indicators below the norm means a malfunction in the battery or BMS board.
Loose battery contacts
A clear sign of a poor-quality connection of contacts is the behavior of the LEDs when the product is turned on. If they all light up at once, then they start to go out one at a time, and then the cycle repeats, it is necessary to check the correct connection of the contacts.
To carry out self-repair, the following operations are required:
You can understand the success of the operation by the color of the LED, which should change from red to blue.
System reboot
To fix the problem you need:
- Turn off the "charger", and also disconnect the power cable connecting the battery and the controller;
- Connect the charger back, after which the battery should start flashing red, and when the “charging” is disconnected, the color will change to blue;
- Reconnect the power cable;
- Turn on the product. It is necessary to wait until all the LEDs “blink off”, the battery starts flashing at a shorter interval, and the red signal lights up on the controller;
- Connect the charger, after which the LED on it should turn red, and the LED on the batteries will start flashing red.
Carrying out this procedure allows you to reset the errors in the system and return it to its original working state.
Battery wire damage
They should be checked only after diagnosing contacts and rebooting the system. To assess the level of damage to the wires, you need to completely get battery and compartment, and in turn carefully check all bundles of cables for damage.
If they are found, it is necessary to replace the set of wires.
Blown temperature sensor or fuse
Before changing the element, it is necessary to make sure that the battery and the controller are in good condition, for which the output voltage is measured. If everything is in order, then the BMS board must be removed to gain access to the fuse.
It is checked with a multimeter. The normal value is 0 or close to zero. If the device gives a unit, then the sensor is faulty.
To solve the problem, it is enough to install a new element. When removing it, the main thing is not to damage the connecting contacts.
In general, users of electric scooter models in 2017-2018 extremely rarely encounter malfunctions of their vehicles, as high-quality components and innovative technologies are used for their manufacture. And if, nevertheless, the Xiaomi scooter does not charge, then you can solve the problem with the appropriate tools and devices at home.
