Slow charging samsung galaxy s4. Why does an android phone or smartphone take a long time to charge?

If the phone is charging slowly, you do not need to think that the battery has exhausted itself during the 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 rather 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 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 can 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 cease to function.

Broken cable

The most fragile part among the huge list is the charging cable. Due to constant bends, 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 often face this tricky question. People carry their smartphones in their jeans pockets, which causes fine 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 hairdryer 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 drops, various mechanical damages, the adapter breaks down from time to time. To test it for performance, it is enough to 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 begins 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, one 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 the ports of laptops, wireless chargers give very low power and because of this, smartphones begin 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 quickly sits down. All this is due solely to the fact that many background applications are open, due to which a quick discharge of the purchased device occurs. Turning off your phone helps clear RAM, thereby closing running tasks.

Updating the software

It has repeatedly happened that it was after updating the current version of the software that the smartphone began to quickly run out of battery. 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.

If I had a dollar, every time people complain that the battery in an android smartphone takes a long time to charge, then I wouldn't have much left for a millionaire.

This is of course a joke, but there is such a problem. People massively buy phones that allow you to watch movies, listen to music, play games, and everyone understands that such a device can be charged.

It should only be noted that today we charge our smartphone almost every day, but if you do not treat the battery correctly, then for several months, then you will have to connect your device to the charger every few hours.

In addition, there are a few rules to apply to a battery so that in a year the battery does not become only suitable for trash - especially if you have one of the new, chic types where the battery cannot be replaced without a specialist.

It was an introduction, and now I'll tell you in order: why the phone started charging for a very long time, quickly discharged and what to do then.

How long should an android phone or smartphone charge

You can find out the state of the battery of your android device. ...

There are a lot of phones, like smartphones, for example, samsung galaxy, lenovo, xiaomi, meizu, asus, htc, lumiya, etc., and their charging time is different.

A full charge of a push-button phone or a modern smartphone takes on average 0.5 - 5 hours. So with a capacity of 1500 mAh it will charge faster than with a 3000 mAh one.

Moreover. If the phone is turned off, it will also charge faster than when it is turned on, and you are also watching a movie, which is not recommended. Some smartphones support fast charging, then the charging time increases dramatically, but wears out faster.

Therefore, before you start to panic why the phone battery takes a long time to charge, look at the battery capacity - perhaps this is his norm

Reasons why the phone takes a long time to charge and quickly discharges

What is the reason that the phone takes a long time to charge and quickly discharges? The reason is not one, but the main one, of course, is the battery itself.

Perhaps you have the Internet, bluetooth, GPS, player working while charging, many applications, cool wallpapers are open, you are listening to music and so on.

All this undoubtedly affects the charging speed of the battery of an Android phone or smartphone.

Also, the reason may be in the usb connector or controller. The connector can be cleaned, the contacts can be bent.

Another reason is the charger itself. Try another one or from a computer. There are also precedents when the charging speed increased when the cable was replaced (I was convinced personally).

Moreover, you can safely try to change even the original cable, for another - there are examples that the problem is being solved.

Above, I gave only a few reasons why the phone took too long to charge, but here we go.

Summarizing the main reasons for a long phone charge

Bad contact of USB port and micro USB
Bad cable
Bad adapter (charger).
Bad phone or smartphone battery
Bad firmware (upgrade)
Along with charging, many unnecessary processes are running

What to do when the phone started to charge for a long time

If you are, for example, a smartphone samsung galaxy s3, s5, j3 and so on, try to determine what the problem is with the GalaxyChargingCurrent program. With its help, you will be able to determine in which direction to move.

NOTE: an old, worn-out battery can charge faster than a new one - a paradox, but a fact.

You can also calibrate the battery. How - Not always, but sometimes calibration solves the problem.

ATTENTION: wireless charging is available today in some smartphones, for example, Lumi 92, or Samsung Galaxy S4, but it is better not to use it - it significantly reduces the life allotted to it.

IMPORTANT: Do not completely drain the battery. A fully discharged battery and unused for a long time should not be suddenly charged to full - this can put it at risk.

REMEMBER: The increased temperature that accompanies the charging process of the phone reduces the life of the battery and other electronic components.

How to prevent your phone from charging too long

Do not allow full discharge. A partial charge is better than a full charge. Do not expose the battery to high or low temperatures for an extended period.

If you actively use the battery, after a while (a certain number of cycles), its performance will significantly decrease.

Then don't be afraid of replacement. Contrary to what people might think, even on devices without a removable back cover, you can replace the battery, except that this may require handing over the phone to a specialist.

The worst thing that can be is when the phone does not have the ability to replace the battery and the end of its life marks the end of the smartphone.

There are, however, ways that you can charge your phone faster and keep it in good condition for longer.

Tips for Avoiding Long Charging of Your Phone or Smartphone

Best of all, do not charge your device at night - he himself cannot "wake up" to trigger an alarm.

At night, use a weaker charger. Batteries last longer when they are less charged. Charge the battery at room temperature - preferably below 25 ° C and above zero.

If possible, do not fully charge your phone. Up to 85-90 percent is quite enough for a longer maintenance of the condition.

If the temperature increases by more than 10 ° C during the process, then something is wrong. Replace charger.

If you are addicted to fast charging, use a short, thick cable. The current losses will be less. Be careful on hot days - do your work in a cool place. Beware of cheap chargers.

The cheap ones do not take into account the characteristics of the battery. I also recommend watching a video on how to increase battery life in your phone. Good luck.

Samsung Galaxy takes a long time to charge? This problem is very common for owners of used smartphones, since new Galaxy smartphones are 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, the declared capabilities for some reason 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

There are a lot of main reasons why Samsung Galaxy takes a long time to charge. Let's go over them:

The first reason is trivial and occurs quite often - poor quality charger. This can be verified by simply replacing the power supply and cable. If nothing has changed, chances are high that the problem is 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. You can pre-moisten them in ethyl alcohol.
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 a cable is becoming more and more 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.
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. To begin with, 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.
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 a power of only 2.5 W (5B / 0.5 A), and USB 3.0 gives a maximum of 4.5 W (5V / 0.9A).
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 run out of power. 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 Samsung Galaxy takes a long time to charge and quickly discharges, then the cause of this malfunction lies in two cases:

Malfunction in the smartphone software (installed applications and games consume a lot of energy)
Defective battery (swelling, strong heating of the battery will tell you about this)

If in the first case, you can use special utilities to check the power consumption of your mobile device and fix 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 reasons for the long-term charging of the new Samsung Galaxy are:

Problems with the charger.
Battery problems.
There is not enough current in the outlet.
Factory defect or software failure.
Mechanical damage, moisture ingress into the device.
Problems with the charger connector.
The battery has deteriorated as a result of incorrect 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 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:

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 unit-tester-cable-smartphone, and we look at the current consumption on the tester's screen.
Program. Less accurate, but simpler, no purchases required. 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 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 knowingly 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.

Bad contact

Broken cable

Garbage in the USB port

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 breaks down from time to time. 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

Charge from the right source

Turn off your smartphone

Updating the software

Conclusion

A huge number of cases were analyzed in which a smartphone on the Android, iOS platform could quickly sit down 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 of the citizens are used to thinking, sometimes you need to figure out the reason than start coming up with a list of actions. At times, even the most commonplace reason can affect the autonomy of the device. And having dealt with such a trifle, you can save yourself a lot of money without buying unnecessary (unnecessary) parts.

If the 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 cannot find the reason, then return the device under warranty. It often happens that a Xiaomi or Samsung Galaxy S4 phone takes a very long time to charge from a laptop. No need to be surprised. This is not about the phone, most likely the amperage of the laptop's USB port is lower than that of your charger.

Smartphone takes a long time to charge - what to do?

Often times, charging will slowly charge the iPhone due to the deterioration of the battery. You should also check the charger. To check, you can:

use a different charger;
try to charge another smartphone with your charger;
inspect the charge for integrity.

If you decide to use another charger, then we advise you to take the original device. Counterfeit charging may not provide the required amperage. Now you know what to do if your smartphone takes a long time to charge. All of the above reasons are more likely to be branded devices. For example, if your LG phone is charging slowly, then you can simply change the battery.

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

A new smartphone takes a long time to charge, or a few more reasons

Many users are wondering what to do if the phone does not charge well. At first glance, everything is simple. You need to see a specialist. But some would like to fix the problem on their own if possible. On the one hand, it is cheaper, but on the other, 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 has been in water, then look for oxidation.

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

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 is happening 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 only be estimated 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 take over 10 hours. There is only one conclusion - you need to buy a new charger, having previously used a known good charger.

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 fast discharge may be due to the gluttonous software installed 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 work. This approach will not help modern lithium-ion batteries.... But a very deep discharge can do harm.

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 Doctor Battery 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.

Mobile devices are called that way for a reason. Nowadays, 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 up 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 you blame 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 begun to produce protective coatings for 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 a very cold area. In any case, the first thing to do is test it on a different 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 included in the kit. Meanwhile, some modern devices support Quick Charge, and as a rule, there is no QC adapter included in the package, 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 quickly as modern devices of 2015 that support various fast charging technologies. Want to keep up with progress? - you should buy yourself a new modern smartphone.

The battery is out of order

Typically, the 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.
