The smartphone shows charging but does not charge the reason. If the device shows charging but does not charge

Owners of mobile phones often face a problem when the Samsung phone is not charging. If you are also faced with a similar situation and stopped charging Samsung, take urgent action. Do not run this problem.

First, you can make a primary diagnosis yourself. Remember, after what actions the mobile stopped working. If liquid gets into the device, then we do not recommend to continue its further operation, as when trying to charge it, you can damage the board. It is better to ask for help in our service center, where they will make a diagnosis and determine the cause of the breakdown.

Why does Samsung not charge and what should I do? If the Samsung phone does not charge from the computer (computer) of the USB or charger, first you should check the cables themselves. In case they are serviceable, then the reasons can be as follows:

1. the connector itself is defective. In order for the device to work again, the part will have to be changed;
2. the Samsung battery is not charged even if the connector is partially pulled out of the PCB. In this case it is necessary to do a diagnosis in order to determine the degree of damage;
3. the power controller is defective. If it is really damaged, then only its replacement will help;
4. long and slowly Samsung charges if the power circuit is faulty. This detail includes many elements, in order to repair it, you need to make a diagnosis;
5. about 5% are occupied by other problems. Identify such a breakdown is possible only after diagnosis.

Why is the Samsung cell phone battery hot during charging?

If Samsung heats up, this is normal. While charging or talking, Samsung is warming itself because there is an increased consumption of energy.

Do not repair the cell phone yourself, as this can only be done worse.

• At us the guarantee on all device is given at any repair, and not only on the replaced detail.
• After repair, the device undergoes Free Quality Control.

The charging stopped working. Not charging. There is a suspicion that the charging connector is damaged. often charged.

Ragged   or frayed   wire is one of the most common reasons for not charging when you connect your phone to a memory or a computer.

how avoid damage   wires:

What if the cable is already corrupted   or broken:

• The simplest and most expensive way to repair a crash is to purchase of a new   wires.

Connector in phone is damaged

No less common problem is breakage of a connector   on mobile phones. To detect such a breakdown is not very simple, but possible. One of the typical signs of a connector failure is inclusion   charging only in certain positions of the cable connector.

How to fix the problem:

• The first step is to try clean   charging connector. The accumulated dirt often causes many breakdowns;

Defective battery

Problems in the operation of the battery can also lead to the inability to correctly charge a mobile phone, smartphone, tablet or other device. It can be blister, burning out   contacts or simply a loss   capacity due to aging.

To fix such a problem can only be one way - acquiring   and installation   new battery. It is necessary to buy a battery exclusively for your phone model, while it is recommended to choose original   products, because cheap Chinese analogs can be much inferior in quality and capacity.

Problems in the software

Errors   in the software often arise in smart phones, on ordinary mobile phones very rarely there are faults of this kind. Programmatic failures include faulty firmware   device, drivers   as well as installation malicious   applications that interfere with the correct charging of the device.

If the smartphone is not working because of lack of charge   or lack of reactions   to reset the settings will require a full flashing   device. The process of the firmware depends on the specific model of the mobile phone, on some it is enough to download special software and connect the smartphone to the PC. Others will require unblock   loader or enter the device in the firmware menu. Inexperienced users should not do this themselves, it is better to turn to professionals.

Battery not calibrated

This problem may occur when installing new battery   in the phone. It can be manifested the following ways: no response to the memory connection, charging the phone is not up to the end or quick discharge. To calibrate the battery it is necessary to carry out a couple of full cycles of charging and discharging the phone.

Mobile devices are not just called this way. Currently, of course, our devices with you have much more functionality, huge displays that consume a lot of energy, but you can not leave the roots. Smartphones should always remain as mobile as possible. Look at user surveys, the most important parameter for which was the device's operating time.

However, not only the work time determines the mobility of the gadget, but also the charging speed. Currently, there are many fast charging technologies that can charge your device up to 70 percent in just 30 minutes. However, with this some users can have a number of difficulties. Does the smartphone charge 3-4 hours? We will try to find and fix the problem.

Defective USB cable

Before you blame the faulty battery or the next update to a more recent version of Android, try first to check the cable for external damage. The USB cable is not given much attention when it comes to its long service, on the contrary, many manufacturers have begun to produce a protective coating of cables from organic substances, which leads to faster failure, by the way, Lightning is a good example.

Check that there are no places on your cable where the protective coating has torn, it is also likely that the cable was in places with very low temperature. In any case, first of all it is worth checking it on another device. If everything works properly, proceed to the next step, otherwise replace your USB cable with a new one.

Meanwhile, you should also check the USB port for external damage. In addition, it can be corroded if the machine has been exposed to water.

Weak energy source

Try not to charge the smartphone with a computer or laptop, because the transfer of energy in this way is very slow. USB 2.0 transmits up to 2.5W (0.5A / 5B), in turn, USB 3.0 - up to 4.5W (0.9A / 5B).

Defective adapter

Evaluate the power adapter for external damage, if there are no problems, check the adapter's parameters: if the current is only 1 A, the device will be charged more slowly than if it is a 1.5-2 A. It is worth remembering : not every smartphone supports such indicators. Try to always use the standard adapter that comes with the kit. Meanwhile, some modern devices support quick charging of Quick Charge, and as a rule, there is no QC adapter in the kit, it should be purchased separately.

Your smartphone is out of date

If you use a gadget for more than two years, do not think that it will be charged as quickly as the modern devices of 2015, supporting various fast charging technologies. Do you want to keep up with progress? - You should buy yourself a new modern smartphone.

The battery is out of order

As a rule, the battery life is very limited. After 1-2 years, the device will be charged more slowly, and by three years it might even start turning off, for example, after passing the threshold in 50% of the remaining charge. It says only one thing: you need to replace the battery. Owners of devices with a replaceable battery can replace it themselves, others advise to contact the service center.

The problem is you

Try not to use the device while charging. If you decide, set the screen brightness slider to a level below the average, because most of the energy goes to the backlight of the display. Close the running applications from the multitasking window, "kill" unnecessary processes, wakes, for this you can use Greenify or Wakelock Terminator, for example.

Why is the smartphone charging slowly? Search and problem solving    Vladimir Ukhov

You connect the charging cord to a smartphone or tablet, or a USB cable, but the phone or tablet does not charge. Do not rush to panic. Do everything in order, and you will find the problem without difficulty. All below listed is suitable not only for Android phone / smartphone but also for the tablet.

What should I do if the phone does not charge?

Check the charger

The simplest way to do this is by replacing it with a know-how, or doing the same with what it is.

• Remember the percentage of charge (if the phone is already on)
• Disconnect phone
• Connect the charger for 15 minutes
• Activate phone
• Check percentage of charge

If the percentage of charge has increased, then the charger is conditionally suitable.

If the phone is charging but does not charge or charges very slowly

Most often this is the result of using a non-native charger that is not suitable for charging this phone, especially when charging tablets.

How to understand that the charger is not suitable for your phone or tablet on Android?

1. The charger is not "out of the box" or "not native" or fake (carefully examine the appearance of the charger, the brand should be the same as on your phone / tablet is especially true for old samsung tablets)
2. Another charger charges without problems and on the native charge it goes but the phone does not charge
3. The charge rises only when the phone / tablet is turned off (an obvious sign of insufficient charger power)

If any of the above apply, you need to replace the charger, if only your battery is less than one year, if more than a year:

• Try charging any charger to 100% (unplug the phone while charging)
• Check how much charge is enough
• If the charge is enough for a day not to use the smartphone intensively or 2 days of a normal phone, change the charger
• If the phone is quickly discharged and the charge is not enough for a day, change the battery

If the phone / tablet quickly discharges or becomes warm when charging

A clear sign that the battery has worked its life and it's time to replace it, sometimes it happens even with new batteries (fake, not original battery, marriage), but first you need to calibrate the battery (read -)

If the battery does not discharge quickly, but it heats up noticeably during charging, try using other chargers, most often this is due to the use of a non-original charger or "raw / cheap / defective" quick charging technologies, then use the usual charging units for 5 -5,1 volts 1,5-2А.

If you decide to buy a new charger, pay attention to the current and voltage at the output, for modern smartphones and any tablets, with capacious batteries, the output current must be at least 2 amperes at a voltage of 5 volts

Answers to Frequently Asked Questions

Is it possible to discharge the battery completely?

It is not desirable, the batteries are built-in protection against excessive discharge, if it works, it can be charged only in the service center and it will not always be safe, therefore, it is better not to pull to the last percent.

What should I do if the charging slot is loose or broken?

If it's shattered - try other cables (from motorola for example), if broken, only to a service center.

The sensor responds poorly to touching while charging the battery, how to fix it?

The problem is in the charger, you need to use a higher-grade charger with a pulse filter at the output.

The phone is charged only by another charger, what should I do?

If the current on the non-normal charge is greater, there are two possible causes

1. Some process / application on the phone actively uses the processor, consuming a lot of energy, it can be tracked according to the schedule of energy consumption by applications ( settings > battery).
2. The battery has fulfilled its life, it needs a replacement for a new one.

If the phone is slowly charging, then do not think that the problem is only in the charger or battery. In fact, the problem, as well as its solution, can be much simpler. What if the phone is slowly charging or not charging at all? What are the reasons for this problem?

Bad contact

Quite often, inside the USB port or the charger cable, the metal coating has a bad contact. This can be both a defect due to the fault of the manufacturer, and the wear of the cable.

What should I do if the phone is slowly charging due to poor contact? Turn off the device and remove, if possible, the battery. After that, all contacts should be cleaned with something like a thin needle. You need to do this very carefully and carefully. After cleaning, the battery needs to be put in place and the charger connected again. Often this method helps to restore the normal charging process.

Dust and debris in the charging port

Many wear their gadgets in the pockets of jeans, and they have small fibers, which can be the reason that the phone is slowly charging. Masters very often encounter this kind of incident. What to do if the fibers or dust hammered into the connector? It can be brought back to normal by blowing compressed air from the can. You can use a powerful dryer with cold air or a compressor. After cleaning, the phone starts charging normally.

Cable replacement

In all the charger, the most fragile part is the cable. Due to constant bends, it quickly fails, causing the phone to charge very slowly. What to do? The simplest way to diagnose a damaged cable is to temporarily replace it with another one. In the event that another cable with the device works as expected, then the original wire is defective. If not, then the reason is not in it.

Adapter replacement

So, the problem with the cable is excluded, but the phone is still charging slowly? In this case, you need to check for proper operation of the charger itself. If the design allows you to pull out the cable from the adapter, the test will be simple. Often you can run into chargers whose ports have been badly worn due to the large number of connections and outages of the cord.

Also need to check the adapter and cable on other phones. This will help to ensure that the malfunction is not connected to the mobile device itself. And it will also be superfluous to check the outlet.

The main thing is security

Do not charge the device near water or in very wet conditions, as in too hot. Do not hold the device connected to electricity for too long. If it's only charged in three hours, then why leave it on for a full night's charge? Because of this, after a while the phone slowly charges and quickly discharges.

If there is a need to replace the wire or the charger itself, you need to be careful, since cheap copies from Chinese manufacturers can be sources of danger. Recently, there has been an increasing number of cases of fire of mobile phones due to poor-quality adapters.

Battery Replacement

The battery life can not last forever. After 4-5 years of use, its capacity is lost, which is why the phone is slowly charging. The more frequent the processes of charging and discharging, the sooner the battery will deteriorate. If the battery stopped working in just six months of use, then it's not normal. In this case, you should contact the seller.

Sometimes a battery that has a defect can be easily identified after inspection. If it is swollen, it should be replaced immediately.

Charge from the correct source

Many people charge their gadgets from computers and laptops. They have a question: why is the phone charging slowly? The computer ports are too small. The phone will always charge much faster from the socket.

The problem may also be that the adapter is used entirely from another device, for example, from a headset that is not intended for the phone at all. Often you can hear a complaint that Samsung's phone is slowly charging. Thus users charge it by means of the adapter from other models. But all adapters supply a different output voltage.

Software update or rollback to a previous version

Updates on the phone can adversely affect the battery life of the phone. This is especially true when the old model is updated to the new version of "Android." Fresh models are usually optimized for updates.

If the reason lies precisely in this, then you can try to roll back to the previous version of the software. For starters, it makes sense to try to reset the settings to factory settings, as device manufacturers often recommend. This will help to avoid losing data due to a different version of the operating system.

In the same way, the charging problem can be solved by installing a newer version of the software.

Switching the phone off

Often applications run in the background. Their use significantly affects the duration of the charging process. For example, if the browser is running, "Skype" and something else, the smartphone will need a lot more time to fully charge.

You can turn off the device and put it on charge. So the process will go faster.

Calibrating the battery indicator

In conclusion, you need to remember about another type of problem: the indicator on the screen indicates that the charge is full, and the device is very quickly disconnected and requires recharging. Most people think that the battery has become unusable. But often the reason lies in another. This happens after flashing the phone. After its completion, you need to calibrate the battery, which many people forget. The bottom line is that after replacing the firmware, the phone does not know how much charge remains. Therefore, you need to calibrate the display to indicate the correct battery charge.
