The phone does not respond to charging
Over time, mobile devices become obsolete and begin to create problems for their owners. Often the owners of gadgets on Android and Samsung complain that their phone does not turn on and does not respond to charging. This happens for various reasons. From problems in the operation of the technical part of the device to sloppy operation by the owners.
In the article, we will analyze the most common reasons for the failure of a smartphone or tablet. We will not offer banal options for rebooting the device or pulling out and inserting the battery back, since these actions are primarily performed by the user in case of malfunctions of this kind.
Read carefully and draw conclusions for yourself.
Full battery discharge
There is a possibility that the battery is completely dead. On almost all devices, a certain voltage value is set at which the mobile phone will display an indication. If the voltage drops below a predetermined value, then in this case the device cannot be turned on immediately. Even when the charger is connected, the screen will not light up and there will be no indication.
To solve this problem, you need to leave the phone on charge for 35. 45 minutes. Time frames may vary and depend on the wear of the device’s battery. With a lot of wear this can take several times longer. But, on the contrary, if the battery is in good technical condition, then about 10. 15 minutes will be enough for it.
Faulty power supply or cable
This is also an equally common problem. It is always recommended to use the original charger. First of all, you need to connect another phone to the cable and see if charging will go.
If in this case there are no changes, then the malfunction lies in the charger. The power supply or a USB cable.
The most common cable failures are: clogged power connector, broken contacts, broken wires.
You need to check the power supply and the power supply. The easiest way is to connect your mobile device via a USB cable to your computer. If the computer or laptop detects the device and the charge goes, this indicates a malfunction of the power supply.
A common damage to the cable is when the latches bend on the plug from constant use. In this regard, the plug does not fit tightly in the connector and contact is lost. It will not be possible to fix such a breakdown and to fix the problem it is necessary to change the cable.
Dust or other particles entering the device connector
The constant use of the smartphone in various conditions leads to a clogged connector for charging and headphones. This cannot be avoided. Dust and various small debris are constantly around us, even in the pants pocket, where the phone is usually located.
It is not necessary that the connector becomes clogged. A small speck of dust can interfere with the contact. Getting rid of the problem is quite simple. You need to turn off your smartphone and use a needle or other thin object to clean visible particles and blow out the connector.
When cleaning, do not be zealous. An excessive load can adversely affect the state of the contacts, up to their breaking or damage to the loops.
Do not forget about the battery itself. A faulty battery does not always have visible signs. Bloating or external damage. The reasons why the battery is out of order can be varied.
The most common situation is as follows: the battery was charged, the phone showed a charge level, but suddenly turned off and stopped responding to attempts to turn on. To detect a battery breakdown with full confidence, you need to ring it with a multimeter. In the absence of a signal on the contacts, we can confidently talk about the death of the battery. If, when the battery is dialed, the voltage value is in the range from 2.8 to 3.6, then in this case the battery is working, but completely discharged.
In this case, you need to put the phone on charge. After 20 minutes, measure the voltage at the contacts again. If the value remains the same, then the problem lies in the charger of the phone.
Power Controller Failure
The problem may lie in the motherboard, namely in its separate node. The power controller. If the diagnosis showed a malfunction, then the master in the service center will need to solder it from the donor or buy a new one. Not every master will undertake such a job.
Power connector failure
There are cases when the source of the problem is hidden in the connector or in the device’s loops. This problem is serious, and not every ordinary user will be able to deal with it. For a better diagnosis and repair of the device, you must contact the service center.
Lack of response to charging due to flown firmware
The reason for this behavior of the smartphone may be a software failure. But in this case, the device will show some signs. A light indication, a blinking screen, the ability to enter the Boot menu. If it turns out to go into Recovery Mode, then the point is in the firmware and you will have to reinstall it.
What measures should be taken to avoid such problems?
Each device has a specific resource and expiration date. But, adhering to banal tips, you can extend the life of your device:
- From time to time, inspect the power connector for small particles of dust and debris. If you find them right away, this will help to protect the connector from dust penetrating deeper, from where it will be an order of magnitude more difficult to remove.
- Avoid exposing your device to frequent temperature fluctuations. Temperature differences contribute to the appearance of condensate, which accelerates the oxidation at the contacts.
- Charge the device only with the original charge. The easiest way to protect the wire from quick wear is to put the spring from the handle on the place of potential cable wear.
- Sometimes it is necessary to perform full charge-discharge cycles of the battery. A full cycle is to discharge the device before turning it off and charge it to 100%.
- You should not use cheap Chinese portable charging. They are not able to provide the necessary current to charge the device and have a negative effect on the state of the battery.
- No need to leave your phone connected to charging all night. Many say that this has no negative consequences, but there is another opinion. The device is constantly “recharged”, which has a negative effect and accelerated wear of the power controller.
So, these are all currently known solutions for Android on Samsung and other brands, when the phone does not turn on and does not respond to charging. Share in the comments, did you manage to fix the problem?
Modern smartphones are complex and quite delicate. On one “beautiful” morning, you may find that the gadget that has been charged does not work. Today we will figure out what to do if the phone does not turn on and does not boot, and how to fix this problem at home.
There are not so many answers to the question why the phone does not turn on, what could be the reason for its quick discharge and what to do in such a situation. Consider the most common options and solutions.
Adapter malfunction or lack of contact
The most common reason why the phone does not load or is quickly discharged is a charger malfunction. To verify this, you need to connect the gadget to another power supply. If it started to charge, then you found the reason and the problem was precisely in the charger. You can do the opposite, connect a known-good phone to a suspicious power supply. Thus, you are guaranteed to verify its malfunction.
If the smartphone does not charge with a working power supply, check the connector of the contacts. A clot of dust may clog into it or pet hair. Gently, with a wooden or plastic toothpick, clean the connection jack on the phone and try again.
If a removable battery is installed on the phone, check the contact tightness and condition. It is likely that they oxidized from moisture or bent when the battery was inserted after a fall.
Another opportunity to “revive” the battery or to verify its serviceability is to use a universal charger. In common parlance, it is called a “frog” and is capable of charging any removable battery from a household electrical network.
One of the reasons why the Android phone does not turn on is the use of an SD card with a larger volume than stated by the manufacturer. Craving for user experiments in the blood. If the specification says that you can use only 32 GB, they will definitely try 64. With a high degree of probability, the device will recognize the card. It will work normally until the recorded amount of information exceeds the declared support.
If after a software failure the phone stops turning on or does not boot, just remove the problem memory card from it. Forced reboot will bring the smartphone to working condition.
System errors and failed updates
System errors, or a resource-intensive application that is not completely unloaded from RAM, can lead to the battery starting to run out quickly, as a result of which the phone disconnected and does not start again. A malicious program may behave similarly. The virus, if its task is not to extort, works in the background. At the same time, he tries to use all available resources as quickly as possible. If the Android phone, in the standby state, is discharged faster than usual, you should check it for infection and force a reboot. Further actions depend on the results of the antivirus scan.
If the smartphone is clean and charged in normal mode, there is no reason for concern. Otherwise, if the device does not start or the phone is quickly discharged again, a full reset and reconfiguration will be required.
An unsuccessful software update may lead to the phone not responding to user actions or simply disconnected. Typically, this behavior is easily “cured” by a reboot.
In the event of a failure when flashing to the new OS version, the situation is a little more complicated. When the phone starts up, but the download does not go beyond the splash screen, the recovery mode can save the situation. What to do and how to enable Recovery Mode for a particular phone is best found on the manufacturer’s website or in the documentation for the device. When this is not possible, try universal methods. The vast majority of Android smartphones support its inclusion by pressing the power keys and volume control. Will it be an Up or Down button, depending on the device manufacturer. You can try both options in sequence.
Some users believe that physical damage is when the phone fell on a hard surface and shattered. Until that moment, he also fell twice, but only “slightly” scratched and crumpled. Meanwhile, it is impossible to exclude the appearance of hidden defects from impact on the gadget’s case. Damage to internal contacts will lead to the fact that the Android phone does not turn on and does not charge, and sometimes it worked and suddenly turned off. So if your phone crashes, it is impossible to fix the malfunction of the system board yourself and you will have to contact specialists for a complete diagnosis and possible replacement of components.
If the phone does not turn on even after you have tried all the probable reasons, you should contact the service center. Without showing undue initiative in trying to resuscitate him, you will save time for yourself and the nerves of specialists.
