Samsung galaxy s4 phone takes a long time to charge. Samsung galaxy battery charging slowly

Problems with chargers and batteries in mobile technology occur quite often. As a result, phones stop charging or hold a charge. One of the most common problems is that the phone takes a long time to charge. This occurs after prolonged 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 the handset, when the owner continues to use the old memory (it is quite natural, given that almost all phones now have the same connectors). Due to different charging currents, the charging speed may be slow. Therefore, for successful replenishment of the battery capacity, it is necessary to use only complete chargers.

If the complete charger is out of order, you should buy a new "charger" with a suitable current strength in the nearest communication store - compare the parameters on the original charger and on 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 is diagnosed using a multimeter. We disassemble the charger, switch the multimeter to ammeter mode, turn it on in the open circuit and look at the current strength.

How to find out the initial indicator of this parameter? It can be estimated only roughly - if a 2000 mAh battery was charged in 2 hours, then the current in the circuit was just over 1000 mA (taking into account 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, having previously used a known good charger.

2. We deal with the battery

Does your phone take a long time to charge and discharge 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 might argue that the rapid discharge may be associated with a voracious softwareinstalled on the phone. This is true, only the charge rate remains practically unchanged.

When addressing this problem to the employees of communication salons, you can hear the following recommendations - the phone must be completely discharged, then charged for 10-15 hours, repeating this cycle 3-4 times. 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 do harm.

3. Understanding the software

Is your phone charging slowly? It is possible that you have used programs to save battery and manage charge. A typical example of this is the Battery Care application - it provides for some interesting multi-stage charging scheme, supposedly providing a better filling of the battery with electricity.

If you actually used one of these apps, try uninstalling it, reboot and try charging the phone again. If you checked the charger, replaced the battery and removed all the profile software, but nothing helped your phone, try taking the device to a service center - here it will be diagnosed using measuring equipment.

Sometimes faulty electronics are the cause of the slowdown.

If the phone is charging slowly, you do not need to think that the battery has exhausted itself during continuous operation of the device, the reason may be much simpler. You can solve the problem that is associated with slow charging of the smartphone quite quickly by sorting out 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 it will turn out 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 himself.

Bad contact

At times, it is because of bad contacts that the smartphone takes an extremely long time to charge. This can be either a damaged USB charging cable, or a manufacturer's defect, because the contacts on the battery can be clogged. Dealing with this problem is easy enough. If your smartphone has a removable battery, you need to remove it and clean it with a thin needle - the metal cover 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 fails, and under such circumstances, the smartphone begins to charge for an extremely long time. With this problem, there can be no question - "What to do?" After all, the answer is quite simple, you need to go to the nearest store where accessories for mobile equipment are sold and buy a new cable there, provided that this is where the problem lies.

Garbage in the USB port

Another reason why the smartphone starts to charge slowly is, of course, garbage in the port where the USB charging cable is inserted. The reason for the trash is extremely simple, and the technicians who are involved in the repair of mobile equipment are often faced with this tricky question. People carry their smartphones in their jeans pockets, which causes small fibers to enter the port, clogging up the connector and charging the phone slowly. You can even cope with this problem 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.

Incorrectly working adapter

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

Battery problem

You need to understand that nothing is eternal. Almost everything can fail on any given day. The battery also has an expiration date. And it is about five years old. After this period, the phone can, in general, start discharging in almost an hour, it will take a long time to charge and there will be a lot of different problems (shutdown in the cold, and so on). The only viable option in such a situation would be to buy a new battery. If the battery starts to behave incorrectly after six months of use, this is an abnormal case and then you should contact the seller with claims.

Charge from the right source

Some users start charging their smartphone from different sources - it can be: laptops, computers, various wireless chargers, and so on. Referring to this category, you should not ask in service centers: - "Why does the phone take a long time to charge." The only reliable source for charging your smartphone will be the socket. The whole reason lies in the fact that laptop ports, wireless chargers give very low power and because of this, smartphones start to charge for a long time.

Turn off your smartphone

At times, it is the reboot of your own device that helps to solve the problem, because of which the smartphone sits down quickly. All this is due solely to the fact that many background applications, because of which there is a quick discharge of the purchased device. Turning off your phone helps to clear rAM, thereby closing the running tasks.

Updating software

It has repeatedly happened that it was after the update of the current version of the software that the smartphone began to discharge quickly. It turns out that an incorrect firmware update can affect the autonomy of a smartphone. The solution to this problem is to rollback to the previous version of the software.

Mobile devices are called that way for a reason. At the present time, of course, our devices have much more functionality, huge displays that consume a lot of energy, but you can't get away from the roots. Smartphones should always remain as mobile as possible. Take a look at the user polls, the most important parameter for which was device uptime.

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

Before blaming a faulty one or the next update to a more recent version of Android, try to first check the cable for external damage. Not much attention is paid to the USB cable when it comes to its long service life, on the contrary, many manufacturers have started to produce protective sheathing of cables from organic substances, which leads to faster failure, by the way, Lightning is a good example of this.

Check to see if the protective cover has torn on your cable, and it is likely that the cable was in very cold places. In any case, the first thing to do is test it on another device. If everything works fine, go to the next step, otherwise replace your USB cable with a new one.

In the meantime, the USB port should also be checked for external damage. In addition, it may corrode if the unit is submerged in water.

Weak source of energy

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

Defective adapter

Evaluate the power adapter for external damage, if no problems were identified, check the adapter parameters: if the current is only 1 A, the device will charge slower than in the case of 1.5-2 A. However, it is worth remembering : not every smartphone supports such indicators. Always try to use the standard adapter provided. Meanwhile, some modern devices support Quick Charge, and as a rule, there is no QC adapter included, it should be bought separately.

Your smartphone is outdated

If you have been using a gadget for more than two years, do not think that it will charge as fast as modern devices of 2015 that support 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

Typically, battery life is very limited. Already after 1-2 years, the device will begin to charge more slowly, and by the age of three it may even start to turn off, for example, after passing the threshold of 50% of the remaining charge. This only says one thing: the battery should be replaced. Owners of devices with a replaceable battery can replace it themselves, others are advised 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 average, because most of the energy is spent on the display backlight. Close running applications from the multitasking window, "kill" unnecessary processes, wakelocks, for this you can use Greenify or Wakelock Terminator, for example.

Samsung Galaxy takes a long time to charge? This problem very often happens with the owners of used smartphones, since new galaxy smartphones very rarely subject to factory defects.

To date, new models of Samsung Galaxy phones have introduced special accelerated charging technologies, which make it possible to replenish the device's battery by 70% in just half an hour. However, for some reason, the declared capabilities do not always work, so now we will try to consider the difficulties that users may have.

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

The main reasons why Samsung Galaxy takes a long time to charge can be quite a lot. Let's go over them:

1. The first reason is trivial and occurs quite often - poor quality charger. To verify this, simply replace the power supply and cable. If nothing has changed, chances are high that the problem lies with the hardware of the device - battery, USB connector, or power controller. The first step is to gently clean the connector using a regular toothbrush or toothpick. They can be pre-moistened with ethyl alcohol.
2. Mechanical damageUSB cable. In case of 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 part in terms of the length of uptime. Moreover, in recent years, the use of organic harmless substances as a protective coating for the cable is becoming increasingly popular, which is an additional factor in its accelerated wear. As an example, you can remember the same Lightning. So, it is worth checking the charging cable for breaks in the protective coating and testing the performance on other devices. If no problems are identified, you should look for the cause of the slow charging in another, otherwise a simple replacement of the USB cable with a new one will help. Also, the USB port itself may be damaged, or corroded if it came into contact with water.
   
3. Battery failure. Any battery will fail over time. As it ages, the phone will have a poorer charge and take longer to replenish. The battery life is 500 full discharge-charge cycles, usually in 2-3 years. First, it is worth checking the capacity of the battery and understanding what 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 fail too quickly. Therefore, you should only buy a replacement battery from a specialized store.
   
4. Weak power supply. Connectors on a stationary PC or laptop cannot always provide a good current for charging a gadget. Indeed, according to the specification, USB 2.0 ports provide power of only 2.5 W (5V / 0.5 A), and USB 3.0 gives a maximum of 4.5 W (5V / 0.9A).
   
5. Incorrectly installed update. It has repeatedly happened that it was after updating the current version of the software that the Samsung Galaxy began to quickly discharge. It turns out that an incorrect firmware update can affect the autonomy of a smartphone. The solution to this problem is to rollback 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 quickly discharges, then the cause of this malfunction lies in two cases:

1. Malfunction in the smartphone software ( installed applications and games consume a lot of energy)
2. Defective battery (swelling, strong 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 fix the errors. Then in the second it is necessary to replace the old battery with a similar new one.

It is important to remember that accessories for mobile phone should be bought in trusted stores to avoid counterfeiting.

Why new phone Samsung takes a long time to charge

In most cases, the reason for long charging new Samsung Galaxy are:

1. Problems with the charger.
2. Battery problems.
3. There is not enough current in the outlet.
4. Factory defect or software failure.
5. Mechanical damage, ingress of moisture into the device.
6. Problems with the charger connector.
7. The battery has deteriorated as a result of incorrect charging the first time.

I already told you how to check and fix these problems 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 know the cause of the Samsung Galaxy Slow Charging issue. You should find out if 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 the charging process. This can be done in two ways:

1. Hardware. Considering the tiny size of the contacts and their internal arrangement, it is very inconvenient to use conventional testers. It is best to purchase a USB tester and take a notoriously powerful power supply (say, 2000 mA) with a USB port. We connect in series the block-tester-cable-smartphone, and we look at the current consumption on the tester screen.
2. Program. Less accurate, but easier, no purchases required. Install from Google play Ampere app. In this case, you will see the charge current directly on the smartphone screen.

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

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

Video: Why Samsung Galaxy takes a long time to charge

Why is my Android charging so slowly? Why does the battery drain too quickly? These are very frequently asked questions on the Internet. Good smartphones come with powerful hardware and high-resolution displays that consume a lot of battery resources. In addition, there are a number of other reasons.

Broken cables and adapters

The first culprit for slow charging is often the USB cable. They bend, curl, curl: none of this is great for maintaining a strong connection and flowing power.

If the cable that came with your device is no longer reliable or you just lost it, beware of buying cheap options. Higher quality cables have copper wire (some manufacturers use aluminum and other substitutes that cannot withstand stress) and a thicker rubber sheath around the wire, making them more resistant to damage.

The USB connector itself also wears out. For example, when you connect a cable to an adapter or phone, it dangles, falls out, clogs up with dust. If it is the problem, then you can try cleaning the dust with a toothpick.

You may have a damaged charger. If your phone won't charge from a wall outlet, try checking the power adapter (a small box that plugs into a wall outlet). If it is too hot or, conversely, cold, this may be an indirect sign of breakdown. Connect your phone to your computer via a USB cable. If it starts charging, the problem is with the adapter. Go to any hardware store and buy a new one for your device model.

Weak power supply

This is the simplest possible reason for slow phone charging. You can easily check if this is the case by simply plugging the USB into a different adapter. If the charge is still not flowing, chances are that the outlet itself is not working. You can try charging your phone from a wall outlet in another room.

Absolutely all modern smartphones have the ability to charge not only from a power outlet, but also from other devices, such as a computer or an external power bank via a USB port. But alas, if you are using a computer then your phone will charge very slowly. The point is that the output voltage will be too low. And this, under ideal circumstances, any damage to the USB cable or ports could disrupt the meager power flow and take even longer to charge.

Likewise, if you're using wireless charging, you'll get a pretty slow charge. Nobody says wireless charging isn't cool, but speed will have to be sacrificed.

Old software

Slow charging is not only a hardware issue, but also a possible software issue. If the software crashes or is out of date, the phone also cannot consume power, and, accordingly, charge.

Also, if your phone has a problem with an old charger after you have updated your gadget to a newer version of Android, your phone is probably not capable of working with it. Then you should consider downgrading to an earlier version of Android or purchasing a new charger.

Simultaneous use

Even though the screen is the first furious consumer of charge, you may have some apps running in the background and consuming energy all the time. As a result, your phone charges much more slowly.

The simplest solution here is to clean the task manager and check it more often for possible applications running in the background. When you find an app that is consuming a lot of power, try uninstalling it and analyzing battery life and charging speed to see if those numbers will improve over the next few days.
