Phone does not turn on. The screen blinks when charging
Let it charge, if it doesn‘t start. complain already
Battery is broken. Gets a 4 when charging.2 volts, the controller turns off charging, but because the battery is dead, the voltage drops and the phone goes out. Then the charging process starts again. And so on in a circle. You can only see the tablet or Smart turning on and off alternately. So change the battery.
My Samsung also did not turn on, so I removed both sim cards from the phone and the memory card, then the phone turned on. Then I installed both sim cards one by one into the phone: the phone turned on both with one sim card and with two sim cards, but when I installed the memory card that I removed the phone again stopped turning on. After that, I installed another memory card, and the phone started to turn on. And what’s interesting: the memory card taken from the phone (which did not turn on the phone), I put the smartphone and it was fine, such miracles. I did not install this memory card back into the phone, I just changed the memory card files with the computer.
VadimF says it best. Same situation. my pretty old smartphone battery died (and I’ve been using it every day for several years, like 4). Every year the battery becomes weaker and weaker, degradation is visible to the naked eye. Today I put the Smart off (did not turn on) to charge, charging screen appears and immediately (2-3 seconds) turns off. In 3 seconds it appears again. and then shuts off again. Read the comment of the gentleman. took the battery from a completely different smartphone, put it to the contacts observing polarity (WARNING!). and oh well, the machine worked. (I copied the answers for better visibility, don’t be angry, just now I realized that this is the first time I’ve read the Комментарии и мнения владельцев in a few years)
On the Xiaomi phone, the red light flashes when charging
Xiaomi phones have an advantage that makes them pleasant to use in everyday life. the LED indicator light on the front side. Depending on the application used, or the situation, it flashes in different colors.
If there is a notification of the Telegram app. the color is blue, if Viber. purple.
But what does blinking red mean when the battery is charging or the device is disconnected?
The red light may indicate that the battery is deeply discharged
If Xiaomi has been disconnected for a long time, the battery could be deeply discharged and the remaining energy is not enough to turn on the smartphone, this is signaled by the red indicator.
Nothing happens when you try to turn on the smartphone, just a flashing red light.
In this case, connect your smartphone to the included charger for up to 6 hours.
After that, try to turn the phone on again, if the problem is a deep discharge of the battery, it will turn on.
Also red light is on during normal charging the battery when the charge is below 10% of maximum, even if the phone is on and working properly.
The charger has failed
The charger, like any other gadget, can break and malfunction. It begins to give current of the wrong voltage and not the strength for which the battery is designed. The chip that controls the transfer of power from the mains to the battery sees this and signals in red that if you continue to use the faulty charger, you could permanently damage the phone or the battery.
This indicator does not always indicate that the charger is broken, but it is easier to check this version.
To check, connect Xiaomi to another charger, if it was the charger, the light will not blink red.
You will only need to buy a new Xiaomi branded charger and continue to use your smartphone as usual.
Red color. possible battery breakage
This operation is done at your own risk, the author of the article takes no responsibility for the consequences. Recommendation. contact a service center.
You have replaced the charger and the red light is still on? Then let’s check the battery itself.
It is difficult to do, especially if the design of Xiaomi does not allow for easy disassembly at home. In this case there is only one thing left. to give the phone to the service center for diagnostics.
If your Xiaomi can be disassembled you need to do the following:
- Open the back cover
- Find the battery cable, connected to the board
- Carefully disconnect it
- Connect a known working charger to the phone and turn it on
- If the smartphone works, plug the battery cable back in
- In this case there is a chance that there was a malfunction of the battery controller and when reconnected it returned to normal
- If this operation did not help. take the phone to the service center
Contacts of the USB socket are damaged
Rough or careless handling of the phone when connecting the USB cable breaks the internal structure of the USB socket, leading to shorts, loss of the necessary contact or physical damage.
To check the working order of the USB socket at home you can connect a known working and faulty charger to it.
If the red light turns off, it is not the jack. If not, then there is a chance that it is out of order, especially if you have a suspicion of its integrity upon visual inspection.
To repair the pins or to replace the socket you must have the necessary tools and go to a repair shop. Do Not Do This at Home.
Loss of contact inside the USB cable will also cause the LED to blink red
Failure of the cable as well as of the USB plug is caused by rough handling.
Fortunately, it is very easy to check the cable. just replace it with another one.
If the indicator changes color, it means that the problem was in the cable, just buy a new one and replace the old one.
Breakage of the controller of the process of charging the phone
On a common board, where soldered a lot of chips and controllers, there is always one, which controls the process of charging the battery.
As a result of a defect in the manufacture, water entering the smartphone or mechanical impact, this chip can break.
To be sure that it is because of the red light burning at home is impossible, because you need to disassemble the phone and use special equipment to test the chip. Only after testing it is possible to unequivocally assert the cause of the failure.
Short circuit on the common board of the phone
Short circuit. the most insidious cause of the red light on Xiaomi.
At home it is impossible to determine the cause of a short circuit at all, moreover, it is impossible to determine where exactly it happened and what to do now.
The only advice in this case is to apply to a repair shop.
After a short circuit, as a rule, you need a serious repair with the replacement of the failed element, and this requires a new element, knowledge of how to remove the old and install the new and how to start the phone after the procedure.
Algorithm of searching of the reason of blinking of red light indicator on Xiaomi phones
Steps to take to determine the true cause of the red color:
- Leave the phone connected to the charger for up to 6 hours (assuming that the charger and USB cable are known to be working)
- Change the USB cable for another one
- Connect the phone to another charger
- Visually inspect the USB socket, assess its condition. If there is any foreign object inside try to get it out carefully. If the appearance is not suspicious, go to the next step
- Take your phone to the service center for diagnostics
Find out the reason
Before you take your cell phone to be repaired, find out the reason why your phone stops charging. First of all check if the socket and the charger are working properly. Just plug the charger into a different socket. If everything is okay, examine the charger. Often the cord gets bent and the contact is broken. This can be noticed if, by rubbing the cable, charging resumes, and when returning to the previous state, it disconnects. In this case you need to replace USB cable.
To determine the state of the power adapter, you need to connect the phone to your computer or use a different charger. If the process has begun, it is time to buy a new charger. A faulty adapter often has a cold or too hot case, so the phone doesn‘t charge well. Buy a new adapter if you can be sure that the phone is recharged by a different charger.
Examine the charging plug
Sometimes the charging slot on your phone gets dirty. Check for dirt by looking into the socket with a magnifying glass in a good light. Accumulated dust causes poor contact of conductors, interfering with current flow. We recommend using special anti-static tools (anti-static brush, tweezers, etc.) to clean the connector.п.). Operation should be performed with phone turned off, if battery is removable it is recommended to remove it. The use of improvised tools is not recommended, because.к. It can cause damage to the socket, if you do not have the necessary tools, please contact the service center to perform the works.
Checking the battery
If you have switched your smartphone on to charge and the phone shows charging, but does not charge, it indicates a battery failure. In this case the repair of the phone can help. Each power source has its own lifetime, and once it is exceeded, it becomes worthless, when the owner of the smartphone has already forgotten about it. Usually the old battery swells, the thickness increases. If it is tested, the result will show that it is time to replace the battery. It is necessary to choose the battery responsibly, because the phone may be incompatible with the non-original battery.
Clean the contacts
It happens that if you replace the battery with a new one your phone still won’t charge. This happens with old phones in which the contacts at the junction with the battery oxidize. It is necessary to clean the contacts with alcohol.
Your cell phone doesn‘t turn on
It is possible that the phone charges but does not turn on. After connecting your smartphone to the charger you suddenly find that the indicator light is blinking and the device does not respond to turn on. This may be due to the following reasons:
- not enough time has passed to recharge. the battery has run out of power and requires a longer time to recharge;
- If the phone is used in deep freezing temperatures, it becomes significantly overcooled, which causes its disconnection (similar situation with overheating). Keep the device at room temperature for a while before turning it on to charge;
- the battery is worn out and needs to be replaced;
- Charger or cable not original/faulty. Charge light is working, but battery is not actually charging. The reason is a weak charger capacity that is not enough for a full charge or a defective cable. Use of original or certified chargers and cables is recommended.
- running applications interfere with recharging. Wi-Fi is on, causing strain on the device. You need to disable wireless connection, GPS, mobile Internet, running programs. It is recommended to scan your smartphone for viruses using antivirus software downloaded from the official site, since unlicensed software may be perceived as a virus. The virus program can consume the resources of the phone so that when you turn on the charger the LED will be working, but the charger won’t be charging.
Sometimes users recharge their smartphone while listening to music or watching video. In such cases, the charge capacity may not be sufficient to recharge the device and the battery level may not increase, but remain at the same level or even decrease.
Update the phone firmware or rollback to the old operating system
If the phone does not turn on, you need to download the firmware from the Internet on your computer. Then proceed as in previous point. You can download the iPhone firmware directly from iTunes. At the beginning of the work you need to select the “update” item and specify the path to the downloaded firmware. The firmware for the phone must be downloaded in advance. Connect the device to your PC by cable and follow the instructions.
