Samsung a3 only charges when turned off. Why doesn't my laptop charge when it's plugged in? Checking the battery and installed software

Does your phone only charge when turned off? It is quite logical that this should not happen - the battery must be charged in any mode. Why is this happening? The reasons for this behavior are not always clear, but in some cases we can try to deal with the problem ourselves.

If the phone does not respond to any influence, you should take it to a service center. But first, let’s try to cope with the task ourselves. In our review we will look at several ways to repair and test mobile devices:

Let's check the functionality of the charger;
Let's try replacing the battery;
Let's look at the installed software.

We will leave a trip to the service center as a last resort.

Why does my phone only charge when it's turned off? The reason for this may be a malfunction of the charger. Therefore, you need to take another charger and test it on your phone. If charging still starts, we get dressed and go to the nearest communication store to buy a new one. Charger to replace the one that failed.

We recommend that you purchase a tablet charger with a high charging current– this will provide more fast charging battery. If you tried another charger, but it did not give any results, you can do the following - use further tests or visit a service center.

We choose the first option and continue testing - what if we can localize the breakdown ourselves? At least we'll save money on repairs.

Checking the battery

If the phone only charges when turned off, we may suspect a battery problem. You need to try to replace it - if possible, rent a battery from friends. If this is not possible, you will have to purchase it at a communication store. new battery.

We install the battery obtained in one way or another into the phone, connect the charger and check. Did the indicator show the presence of charge? Great - we wait until the end of the procedure and check the discharge rate (just in case). You can throw away the old battery - it cannot be restored.

If the charging process still does not start, then the problem was not with the battery. We just have to check installed applications and perform some other operations.

If you purchased a new battery, but it turned out not to be the problem, do not worry - you can use it as a spare. When you find yourself far from the nearest outlet, it will help you make an important call or access the Internet (keep it charged).

Software check

If you have already checked the battery and charger, everything turned out to be intact, but the charge still does not work, you need to check the software installed on the phone. Do you use trickle charging apps? Installed Battery Doctor to extend the deadline battery life? Demolish all this software, clean it using Clean Master or any other “cleaner”, reboot and try connecting the charger.

If the problem was in applications, try using their analogues. Applications often create conflicts in the system, interfering with normal charging. Sometimes the damage to the system is so serious that removing the software is not enough - you need to do a general reset to factory settings. If these steps do not help, all that remains is to contact a service center - it is quite possible that the problem lies in a faulty charge control system.

Before performing a master reset, be sure to create backup copy important data. Otherwise, you may lose valuable files.

There are various reasons why the phone only charges when it is turned off. And this is a problem, because modern gadget It requires a large battery supply, consumes a lot of energy, and sometimes you have to charge it while using it, watching a movie, playing a game, etc. It is extremely inconvenient to do this only when it is turned off, because in this way the device is simply inaccessible most of the time.

And in general, it’s unusual to charge the phone only when it’s turned off. But it is worth noting that for some models of tablets and smartphones this is the norm, which is provided by the developer. Although this is stupid, it is true. But most often, if it is charged only when it is turned off (this also applies to other brands, but on forums people often contact Meizu smartphones), then this is a software or hardware problem. Let's figure out why this happens.

The phone only charges when turned off due to the firmware

The very first and most common version is firmware. This is especially common in Chinese smartphones: ZTE, Meizu, Xiaomi, etc. These phones are sold based on the Chinese shell, and there is no native localization for it. Therefore, users often install third-party software- unofficial firmware.

It is logical that such firmware, developed by amateur programmers and user installed without such skills, it can slow down. Moreover, the problems can be very diverse: poor brightness adjustment range, high heat in passive operating mode, rapid battery discharge, conflict with the charger. It is worth noting that it is precisely because of poor firmware and software problems that something like this most often happens. This can also be related to the hardware, but it is extremely rare.

You can fix the firmware problem. To do this, you just need to return to the official version. The phones have the corresponding functionality. If not, the service center will help. But you can even try to install new unofficial firmware, which, judging by the reviews, works well and does not crash. It is quite possible that it is your current global firmware works poorly and causes a conflict between the charger and the gadget itself. In this case, you don’t have to wonder why the phone only charges when it’s turned off.

Defective power supply or battery

It is logical to look for the cause in the power supply - it can also be the cause. It's easy to check if the power supply is working properly. To do this, you need to try using it to charge another tablet or smartphone. If everything is successful, then the problem is not in the power supply. You can also try charging the problematic smartphone using a laptop or computer by connecting it via USB. If the charging process is activated when the phone is turned on, then you should look for a problem in the power supply.

There is also another rare reason - low voltage in the network. If it drops below 220 V, then some phones and tablets may not charge when turned on. Sometimes the power supply is so weak that it simply does not have time to recharge the phone when it is working. This applies to third parties universal chargers, so it’s best to charge your phone with “native” devices.

It is possible that the problem may be in the battery itself. To check it, you need to find the same one and try to charge the phone with it. If it works, then the problem is clearly in the battery, which means it needs to be changed.

Oxidation or contamination on contacts

Contacts may also be the reason why the phone only charges when turned off. We recommend rubbing alcohol-soaked cotton wool over the contacts on the phone and charger. This may be the problem with them. Unfortunately, this method helps very rarely, but there is always hope.

Which phones are at risk?

This problem is not uncommon. Many users experience such situations. Cheap Chinese smartphones work this way more often than others. However, on the forums you can find messages that Russian Explay phones are charged only when turned off, but this does not apply to the entire line of the manufacturer and not even all models. This just happens, and not only with cheap Chinese budget phones, but also with expensive flagships.

Problem with the charger, software failures and other reasons for improper charging of the smartphone.

The smartphone only charges when turned off - not the best common problem problem faced by mobile device owners. Let's look at the most common problems and methods for solving them.

Charger problem

One of the reasons why a smartphone only charges when it is turned off is a problem with the charger. In the power supply of the charger, the contacts may physically “move away” or oxidize. Because of this, the voltage supplied to the battery will decrease. When the phone is turned on, it consumes energy. A faulty charger cannot supply required quantity current and voltage, so the battery does not charge.

To resolve this issue, try using a different power supply and USB cable. If the smartphone charges when it is turned on, then you need to replace the charger with a new one (here are the main ones). By the way, sometimes it is enough to clean the contacts from dirt and dust.

Firmware failure

Chinese Android smartphones - Xiaomi, Huawei, Meizu - use their own shell. Users often have access to administrator rights - they can install third-party firmware on the gadget. Unofficial firmware, developed by an inexperienced programmer, may affect the operation of the device. For example, the phone will only charge when turned off. This problem occurs because the charger begins to conflict with the firmware.

There are several ways to solve the problem:

Roll back to the official firmware version, which was installed by default.
smartphone to factory settings (performed in the gadget settings).

Presence of viruses

When downloading programs, movies or music, we do not check sites for malware. Performing this action on a smartphone is more difficult than on a computer. For this reason, you can easily “catch” the virus.

Malicious programs block the ability to charge the battery - to do this, background a script is launched that is not displayed in processes. When the gadget is turned on, it does not charge, it simply does not see the charger. The problem is solved when we unplug the device. To get rid of viruses, download and install an antivirus on your smartphone or.

Running applications

Some applications consume a large amount of battery power. Their main problem is that they are poorly optimized for the operating system. Even if you disable these programs, they may continue. This reduces the charging speed of the battery. Sometimes the battery does not charge until you turn off the smartphone.

To solve the problem, open the task manager and disable all applications that are running in the background. You can also download useful utility Advanced Task Manager. The software “kills” unnecessary processes, frees up the mobile device’s memory and extends battery life.

Problem with the controller

A controller is a device that... It regulates the level of voltage and current supplied and ensures that the battery does not burn out while charging. When the controller fails, the smartphone may stop charging when turned on. To identify and solve the problem, you need to take your smartphone to a service center. It is difficult to determine the problem yourself, since this requires disassembling the device.

Battery fault

The problem may be a faulty smartphone battery. When the gadget is turned on, the battery discharges several times faster. Even connecting the charger does not solve the problem - the phone does not charge or charges very slowly. The only way to charge the battery is to turn off the gadget.

You can find out the level of battery wear using the AccuBattery application. Basic information about the battery is displayed in the main window of the utility. Also, using the software, you can determine which programs consume a large amount of battery power. If there is a problem with the battery, the only way to solve the problem is to replace it.

IN modern world A smartphone is an irreplaceable thing, so when your favorite gadget takes a long time to charge or does not turn on at all, this becomes a whole problem, especially if it is a new phone.

First of all, we think about how to charge our gadget, especially when we are in a hurry and are looking for the causes of problems in the phone, but before that we should carefully inspect the accompanying equipment:

Socket - if the wiring is old or there are some other problems with electricity, then this may well explain why the gadget is sometimes charging or not;
Charger - check its integrity, it may be damaged;
Incompatibility of the charger with the gadget - if the inputs are similar, this does not mean that the charging device is suitable for both models of smartphones.

If you are convinced that you do not have any of the above problems, you can move on to studying the phone itself. We will look at the most common reasons why the phone does not accept charge.

The gadget is charged only from the computer

When the phone is charged only from the computer, but the smartphone is turned on and working normally, it is worth checking the charger. But if charging is in order, but the smartphone does not see it or writes that charging is in progress, but in fact it is not, there is a malfunction in the phone.

In some cases, flashing the gadget's firmware or replacing the input helps, but only a professional can do this after examining the device and identifying the problem.

What to do if the phone does not charge, but the charger is connected

It happens that the phone shows charging, but does not charge, and even after several hours of recharging, the battery remains at zero. Or, if you do not charge the phone for a long time, the battery does not accept a charge. In both cases there may be several reasons:

The charger does not charge;
The phone battery is faulty;
There are many applications and other services open.

If the problem is with the charger, the gadget detects the charger, but due to technical faults it does not charge. This situation is probably familiar to iPhone owners, since the cable becomes damaged due to frequent use. Try replacing the wire, maybe that's the problem.

In the case when the problem lies in the battery, you will have to buy a new one or even contact a specialist, see in such smartphone models as Samsung Galaxy S6, LG Optimus Vu, HTC One X has a built-in battery, which means you can’t replace it yourself.

The last option is very rare, but still occurs, especially if you are the owner of a DNS or Fly brand smartphone. In this case, you just need to close all programs, in particular Wi-Fi, the Internet and your favorite games, and then leave your Android alone while it is charging. If the indicator shows that the charge is coming, you can congratulate yourself, you have just fixed the problem.

Poor contact contact

You are familiar with the situation when the phone is working and charging is in order, but for some reason the smartphone does not respond to the device when connected to the network. You don’t even know what to do anymore, since the phone doesn’t charge for a very long time, but the reason for this may be trivial.

From time to time, dust gets into a cell phone with a removable battery, especially for older Samsung models. If you don't clean the inner surface, dirt accumulates, creating a layer that prevents the contacts from connecting normally, which is why the phone won't charge. Try removing the battery, then clean it and the inside of the case with a cotton swab. Also pay attention to the “teeth”; if they are slightly bent, correct this using a match, but act carefully so as not to damage the contacts.

The phone does not charge from the charger

When the phone does not charge from the charger, the reason should be sought in the charger or in the gadget connector. In this case, it’s very easy to find out what’s really not working, just connect your mobile phone to your PC or use a universal frog charger, but using it every day will be problematic, since you’ll have to turn off the phone every time and take out the battery. Another way to charge your phone from an external battery, but this is also not an everyday option.

The smartphone is charging in the opposite direction

Not everyone knows why charging goes in the opposite direction, and the phone does not take charge, but seems to give it away. Faced with such a situation, many are simply perplexed. The reason for this unusual phenomenon is simple - a failure in battery calibration, this happens from time to time with Lenovo phones, but do not panic, because the problem can be solved very quickly.

To eliminate the anomaly, you first need to discharge the battery to such an extent that the smartphone turns off on its own. After that, remove the battery for a couple of minutes and put it back into the phone. Connect the gadget to the charger, but do not turn it on while the charge is running.

The phone takes a very long time to charge

If your smartphone was charged all night, but was not fully charged or the readings were no more than 1 percent, then the problem lies in the battery. Of course, for the first time you can even charge the phone to 100 percent, but not only will the process take a lot of time, but the gadget will also be discharged in literally a couple of hours, if not earlier.

In this case, you have only one option - buy a new battery and continue to safely use your irreplaceable gadget.

You can figure out the problem yourself, but if you are unable to find out why the phone is not charging and you have tried almost all of the above methods, it is best to take your smartphone to a technician, because only a specialist will be able to determine the true cause of the malfunction.

It often happens that the phone does not charge, and this problem occurs on both old and new phones. There are also situations when charging occurs, but very poorly, slowly, up to a day.

Why such problems arise and what to do to solve them will be discussed further.

Problem #1. Broken cable

Often, USB cables burn out, break at bends, or simply stop transmitting a signal. Therefore, the first thing to do if the battery does not charge is simply check the charger cable.

If, for example, a defect is found on it, which is shown in Figure No. 1, you can try to manually press one end to the other or wrap the break with electrical tape.

No. 1. Break location in the charger cable

You can also try taking a toothpick or a regular match and literally picking at the inside of the USB tip in those places shown in Figure 2 with arrows. Can be taken for...

In this article we will try to consider all possible options for why the phone discharges when charging, and how you can deal with it.

Faulty charging socket

The most common reason why a phone dies while charging is a faulty charging socket. This situation occurs quite often, especially when the voltage is unstable or there is a manufacturing defect. "Symptoms" are standard:

The charger is connected. The phone displays an indicator that charging is in progress or there are no indications at all. After some time, the phone does not gain charge, but, on the contrary, spends the remaining charge.

Why is my phone not charging well?

Why does my phone take a long time to charge?

Problems with chargers and batteries in mobile technology occur quite often. As a result, phones stop charging or holding a charge. One of the most common problems is that the phone takes a long time to charge. This occurs after long-term use of the device or as a result of some kind of breakdown. Let's try to figure out why this happens and what to do about it.

Is your phone charging slowly? It is possible that you are using the wrong charger. This often happens when changing handsets, when the owner continues to use the old charger (quite natural, considering that almost all phones now have the same connectors). Due to different charging currents, the charging speed may be slow. Therefore, to successfully replenish the battery capacity, it is necessary to use only complete chargers.

The phone can be used while charging if the charger is of high quality - be it a proven universal one external battery or mains charger. Of course, this will increase the charging time of the smartphone itself slightly, because... You will immediately use up some of the charge.

Myth 2: “Chargers should only be original”

It is completely safe for the battery to use any, preferably branded, chargers - for example, a Samsung can be safely charged with an HTC network charger. Nothing wrong with that. But, again, we are not talking about cheap market chargers, without certification and proper tests.

Hello. I regularly hear from gadget owners the question, why isn’t the phone charging? Has this ever happened to you? If the answer is yes, then you have come to the right place. Today we will look at the main causes of such failures and options for eliminating them.

The cable doesn't work

I put this problem first because USB cables tend to burn out, break at bends, or simply interrupt signal transmission. So you should test the charger first when the phone is not charging. If a defect is found on the cable, you can try to bend it or cover the break with electrical tape.

You can use a standard match or toothpick and try to clean the USB tip from the inside. A simple painting brush is also suitable for such cases, which should be used to go over the inside of the cable. There is a possibility that dust particles or some particles have accumulated there.

Why your phone won't charge: popular reasons and tips for fixing them.

When you urgently need to leave the house, and your mobile device has been on charge for several hours without any visible progress, anyone can get nervous. At such moments, it doesn’t really matter why the phone isn’t charging; the very fact of the malfunction is infuriating. Especially if there were no problems before, but then at the most crucial moment your trusty device let you down.

Why won't my phone charge from the charger?

Before blaming the device itself for the malfunction, it’s worth checking a few things:

The socket is working properly. Charging performance. Its compliance with the working device. The cable and plug are in good working order. Connector status.

In modern homes, wiring problems are extremely rare, unless due to errors during design. But if the wiring has not been changed for 20-30 years, then the sockets may come out of order from time to time...

Why does my phone only charge when it's turned off?

In almost all modern smartphones and tablets, the power connector is combined with a communication interface at the design and software level. For devices on Android and latest models iOS uses USB 2.0 or 3.0.

As for older iPhones (up to and including 6S) and iPads, the Lightning connector was used. This combination improves ergonomics and reduces the number of wires. For example, you can use your phone as a webcam by connecting it with just one cable.

On the other hand, such a technical solution led to the complication of the software and hardware. And this, in turn, caused many problems related to charging or connecting to a computer. Let's try to highlight one of these difficulties, which occurs quite often, judging by the number of topics on specialized forums.

Today we will look at a rather unpleasant problem when the phone runs out of charge while charging. Many users, one way or another, have encountered this phenomenon, especially those who have been using the same smartphone for several years.

And although this situation causes a lot of discomfort, it can be solved, and, as a rule, at home - especially when it comes to system errors.

Why is the device not charging?

Modern gadgets are quite fragile. Manufacturers introduce new functions year after year, improve the performance of their devices, but cannot provide one hundred percent protection for them.

Therefore, users regularly encounter various types of breakdowns: from problems with operating system before equipment wear and mechanical damage.

Often users, faced with such a problem, are perplexed as to how the phone discharges while charging. It's especially annoying when it was left near the outlet overnight, and in the morning...
