Samsung galaxy s4 phone takes a long time to charge reasons. The phone is charging slowly: what to do? Why does a new Samsung phone take a long time to charge?

The name “mobile device” speaks for itself - it should work normally even in the absence of stationary power sources. However, modern processors and hardware in smartphones and tablets, as well as large displays, demonstrate a remarkable appetite for battery power. Despite this, in order to remain attractive to buyers, gadgets with increased power must still remain as autonomous as possible. Moreover, according to the results of many surveys conducted, the operating time of the device is one of the most significant when choosing a suitable model.

At the same time, mobility depends not only on the operating time without recharging, but you should also pay attention to the charging speed. Today, special accelerated charging technologies have already been developed that make it possible to replenish a device’s battery reserve by 70% in just half an hour. However, for some reason the stated capabilities do not always work, so now we will try to consider the difficulties that users may encounter.

USB cable quality

If there are problems, you should not immediately look for updates for your gadget or even buy a new battery - first of all, you should check the USB cable, which may be damaged. Manufacturers often do not pay enough attention to this detail in terms of trouble-free service life. Moreover, the use of organic, harmless substances as a protective coating for cables has recently become increasingly popular, which is an additional factor in its accelerated wear. As an example, we can recall the same Lightning.

So, it is worth checking the charging cable for breaks in the protective coating and testing its performance on other devices. If no problems are identified, you should look for the cause of slow charging elsewhere, otherwise simply replacing the USB cable with a new one will help.

The USB port itself may also be damaged or corroded if it has come into contact with water.

Insufficient power supply

Connectors on a desktop PC or laptop cannot always provide good current for charging a gadget. Indeed, according to the specification, USB 2.0 ports provide power of only 2.5 W (5B/0.5 A), and USB 3.0 provides a maximum of 4.5 W (5V/0.9A).

Adapter problems

It is necessary to check the power adapter for the presence/absence of external damage. If there are none, you can check its quality characteristics. If the adapter is designed to transmit a current of 1 A, charging the device will take longer than when using an adapter that provides 1.5-2 A. In this case, you should take into account the capabilities of the smartphone itself, since not every device can be charged with high currents. It is optimal to use the standard charger supplied in the kit. But modern gadgets often support it, and most often a special QC adapter designed to use this function must be purchased separately.

Outdated smartphone model

If your gadget entered the market more than two years ago, you should not expect from it the same charging speed that modern 2015 models are capable of demonstrating, which have built-in support for various accelerated charging technologies. In order to be at the peak of progress, you need to constantly update your smartphone.

Battery failure

It should be remembered that the battery's ability to provide normal power to the device deteriorates over time. Even after 1-2 years, the smartphone will need more time to fully charge, and after 3 years, the gadget may experience unpredictable shutdowns when the battery charge drops to 50 percent or less. In this case, replacing the battery should solve all the problems - independently in the case of a replaceable battery or with the help of service center specialists in the case of a built-in one.

If the phone is charging slowly, there is no need to think that the battery has exhausted itself during continuous operation of the device, the reason may be much simpler. You can deal with the problem associated with slow charging of a smartphone quite quickly by understanding the cases in which the phone takes a long time to charge. There are several reasons, the main thing is to follow the instructions, and then you will be able to make your own smartphone work perfectly. In some cases, the mobile device not only charges poorly, but also charges quickly. The reasons for these troubles are described in this article, and each user will be able to find out all this for themselves.

Poor contact

At times, it is precisely because of poor contacts that the smartphone takes an extremely long time to charge. This could be either a damaged USB charging cable or a manufacturer’s defect, because the contacts on the battery may be clogged. Dealing with this problem is quite easy. If your smartphone has a removable battery, you need to remove it and clean it with a thin needle - the metal coating of the battery. You should act carefully, because there is a possibility that after the actions taken, the battery will stop functioning.

Broken cable

The most fragile part among the huge list is the charging cable. Due to constant kinks, the cable quickly breaks down, and under such circumstances, the smartphone takes an extremely long time to charge. With this problem, there cannot be a question - “What to do?” After all, the answer is quite simple, you need to go to the nearest store that sells accessories for mobile equipment and buy a new cable there, provided that this is where the problem lies.

Debris in the USB port

Another reason why a smartphone begins to charge slowly is, naturally, debris in the port where the USB charging cable is inserted. The reason for the ingress of debris is extremely simple, and technicians involved in the repair of mobile equipment often face this tricky issue. People carry their smartphones in their jeans pockets, which causes small fibers to get into the port, causing the connector to become clogged and the phone to charge slowly. You can cope with this problem even at home. You need to take a powerful hair dryer and blow out this connector; in addition, you can use a compressor or compressed air from a special cylinder.

Adapter not working correctly

Another reason why a smartphone takes a long time to charge is the adapter. Due to falls and various mechanical damages, the adapter sometimes fails. To check its functionality, just try using it to charge another mobile phone. If a similar problem occurs on your next device, you will definitely have to buy a new charging adapter for your gadget.

Battery problem

You need to understand that nothing lasts forever. Almost everything can fail on any given day. The battery also has an expiration date. And it is about five years. After this period, the phone may generally begin to discharge in almost an hour, it will take a long time to charge and there will be a bunch of other problems (shutdown in the cold, and so on). The only viable option in such a situation would be to purchase a new battery. If the battery begins to behave incorrectly after six months of use, this is an abnormal case and then you should contact the seller with complaints.

Charging from the right source

Some users start charging their smartphone from different sources - these could be: laptops, computers, various wireless chargers, and so on. If you belong to this category, you should not ask service centers: “Why does the phone take a long time to charge?” The only reliable source for charging your smartphone will be a power outlet. The whole reason lies in the fact that laptop ports and wireless charging provide very little power and because of this, smartphones take a long time to charge.

Turning off your smartphone

At times, rebooting your own device helps solve the problem that causes your smartphone to quickly dry up. All this is due solely to the fact that many background applications are open, which is why the purchased device quickly drains. Turning off the phone helps clear the RAM, thereby closing running tasks.

Software update

It happened more than once that after updating the current software version, the smartphone began to quickly discharge. It turns out that an incorrect firmware update can affect the battery life of a smartphone. The solution to this problem is to roll back to the previous version of the software.

Has your Samsung Galaxy taken a long time to charge? This problem very often occurs among owners of used smartphones, since new Galaxy smartphones are very rarely subject to manufacturing defects.

Today, new models of Samsung Galaxy phones have been equipped with special accelerated charging technologies that allow you to replenish the device’s battery by 70% in just half an hour. However, for some reason the stated capabilities do not always work, so now we will try to consider the difficulties that users may encounter.

Samsung Galaxy takes a very long time to charge - the main reasons

There can be quite a few main reasons why Samsung Galaxy takes a long time to charge. Let's go through them:

1. The first reason is trivial and occurs quite often - poor quality charger. To check this, simply replace the power supply and cable. If nothing has changed, there is a high probability that the problem lies in the hardware of the device - the battery, USB connector or power controller. First of all, it is recommended to carefully clean the connector using a regular toothbrush or toothpick. You can first moisten them in ethyl alcohol.
2. Mechanical damageUSB cable If there are problems, you should not immediately look for updates for your gadget or even buy a new battery - first of all, you should check the USB cable, which may be damaged. Manufacturers often do not pay enough attention to this detail in terms of trouble-free service life. Moreover, the use of organic, harmless substances as a protective coating for cables has recently become increasingly popular, which is an additional factor in its accelerated wear. As an example, we can recall the same Lightning. So, it is worth checking the charging cable for breaks in the protective coating and testing its performance on other devices. If no problems are identified, you should look for the cause of slow charging elsewhere, otherwise simply replacing the USB cable with a new one will help. The USB port itself may also be damaged or corroded if it has come into contact with water.
   
3. Battery failure. Any battery will eventually fail. As it ages, the phone will hold its charge worse and will take longer to replenish it. The battery life is 500 full discharge-charge cycles, usually this happens in 2-3 years. First, you should check the battery capacity and understand how much resource is left. If it is significantly less, then all that remains is to replace the battery with a new one of a similar model. In addition, it is possible that the new battery will be of poor quality and will fail too quickly. Therefore, you should only buy a replacement battery in a specialized store.
   
4. Weak power supply. Connectors on a desktop PC or laptop cannot always provide good current for charging a gadget. Indeed, according to the specification, USB 2.0 ports provide power of only 2.5 W (5B/0.5 A), and USB 3.0 provides a maximum of 4.5 W (5V/0.9A).
   
5. Incorrectly installed update. It happened more than once that after updating the current software version, the Samsung Galaxy began to quickly discharge. It turns out that an incorrect firmware update can affect the battery life of a smartphone. The solution to this problem is to roll back to the previous version of the software.

Why Samsung Galaxy Discharges quickly and takes a long time to charge

If the Samsung Galaxy takes a long time to charge and discharges quickly, then the cause of this malfunction lies in two cases:

1. Fault in the smartphone software (installed applications and games consume a lot of energy)
2. The battery is faulty (swelling and excessive heating of the battery will tell you this)

If in the first case, you can use special utilities to check the power consumption of your mobile device and correct errors. Then in the second it is necessary to replace the old battery with a similar new one.

It is important to remember that components for mobile phones should be purchased from trusted stores to avoid counterfeiting.

Why a new phone Samsung takes a long time to charge

In most cases, the reason for the new Samsung Galaxy taking a long time to charge is:

1. Problems with the charger.
2. Battery problems.
3. Insufficient current in the outlet.
4. Factory defect or software failure.
5. Mechanical damage, moisture ingress into the device.
6. Problems with the charger connector.
7. The battery deteriorated due to improper charging the first time.

I already told you how to check and fix these problems above at the beginning of this article.

What to do if the phone Samsung Galaxy takes a long time to charge

Before taking any action, you need to find out the cause of the Samsung Galaxy slow charging problem. You should find out whether it is related to the device itself or to the charging infrastructure (cords, connectors, power supplies). To do this, you need to measure the current consumed by the phone during charging. You can do this in two ways:

1. Hardware. Given the tiny size of the contacts and their internal arrangement, using conventional testers is very inconvenient. It is best to purchase a USB tester and take a known powerful power supply (say, 2000 mA) with a USB port. We connect the block tester-cable-smartphone in series, and look at the current consumption on the tester screen.
2. Program. Less accurate, but easier method that does not require any purchases. Install the Ampere application from Google Play. In this case, you will see the charge current directly on the smartphone screen.

Next, we compare the measured current with the rating current for your mobile device. If the parameters match, then the problem was in the old power supply or cable/connector. Or the smartphone discharges too quickly due to “gluttonous” applications and the charging simply does not have time to “serve” it.

If the charging current is too low even when using a obviously high-quality cable and a powerful source, you need to change the battery and/or contact specialists who service and repair phones.

Conclusion

A huge number of cases were analyzed in which a smartphone on the Android or iOS platform could quickly drain and take a long time to charge. Informed users can now draw certain conclusions for themselves. Not always buying a new battery can solve the problem, as many citizens are used to thinking; sometimes you need to figure out the reason before starting to come up with a list of actions. At times, even the most trivial reason can affect the autonomy of the device. And having dealt with such trifles, you can save yourself a lot of money without buying extra (unnecessary) parts.

If your smartphone takes a long time to charge, then perhaps the reason lies in the battery. If your new phone takes a long time to charge, then you should check the charging, battery and settings. If you do not find the reason, then return the device under warranty. It often happens that a Xiaomi phone or Samsung Galaxy S4 takes a very long time to charge from a laptop. No need to be surprised. The problem here is not the phone; most likely the current strength of the laptop's USB port is lower than that of your charger.

The smartphone takes a long time to charge – what should I do?

Often the charger is slow to charge the iPhone due to wear and tear on the battery. You should also check your charger. To check you can:

• use a different charger;
• try charging another smartphone with your charger;
• inspect the charger for integrity.

If you decide to use another charger, we recommend taking the original device. A counterfeit charger may not provide the required level of current. Now you know what to do if your smartphone takes a long time to charge. All of the reasons listed above most likely apply to branded devices. For example, if your LG phone is charging slowly, you can simply change the battery.

However, the picture with cheap devices is somewhat different. For example, if a Lenovo phone takes a long time to charge, then the problem may be a defective controller. Alas, when assembling affordable gadgets, low-quality, of course, short-lived parts are often used. This is where many problems arise related to charging, software and other issues.

A new smartphone takes a long time to charge, or several other reasons

Many users are interested in what to do if the phone is not charging well. At first glance, everything is simple. You need to contact a specialist. But some would like to solve the problem themselves if possible. On the one hand, it’s cheaper, and on the other, there’s less fuss. Then a few tips will help you. So, if your phone takes a long time to charge and discharges quickly, then:

• change the battery;
• unload the device - remove unnecessary applications;
• check the charger;
• If you can, check the controller;
• if your smartphone was in water, then look for oxidation.

There is a separate post regarding liquid getting into a smartphone. Here we described the simplest reasons why a smartphone takes a long time to charge. If you have any questions, write in the comments!

Problems with chargers and batteries in mobile equipment arise 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.

If the included charger fails, you should buy a new “charger” with a suitable current strength at the nearest communication store - compare the parameters on the original charger and the purchased one.

If the phone takes a long time to charge, then the problem may lie in a decrease in the charging current provided by the charger. Such a breakdown can be diagnosed using a multimeter. We disassemble the charger, switch the multimeter to ammeter mode, connect it to the open circuit and look at the current strength. How can I find out the initial value of this parameter?

It can only be roughly estimated - if a 2000 mAh battery was charged in 2 hours, then the current in the circuit was slightly more than 1000 mA (including losses). If the phone takes too long to charge, and the multimeter shows a current of 200 mA, then the charging process will last over 10 hours. There is only one conclusion - you need to buy a new charger, after using a known good charger.

Does your phone take a long time to charge and drain quickly? All this indicates that the battery in your gadget has exhausted its resource - you need to change it. By replacing the original battery, you will be able to use the device as before. If you choose a non-original battery, the battery life of the gadget may decrease slightly– this is quite natural.

Some may argue that the fast battery drain may be due to power-hungry software installed on the phone. This is true, but the charging speed remains virtually unchanged.

When addressing this problem to the employees of communication stores, you can hear the following recommendations - the phone needs to be completely discharged, and then charged for 10-15 hours, repeating this cycle 3-4 times. About 10-15 years ago, when nickel-metal hydride batteries were in use, such a scheme could have worked. This approach will not help modern lithium-ion batteries.. But a very deep discharge can cause harm.

Is your phone charging slowly? It is quite possible that you have used programs to save battery and manage charge. A typical example of this is the Doctor Battery application - it provides some kind of interesting multi-stage charging scheme, supposedly ensuring better filling of the battery with electricity. If you do use one of these apps, try uninstalling it, reboot and try to charge the phone again.

If you checked the charger, replaced the battery and removed all the relevant software, but nothing helped your phone, try taking the device to a service center - here it will be diagnosed using measuring equipment. Sometimes the cause of slow charging is faulty electronics.
