Samsung Phone Is Charging Slowly

Safe mode startup

By turning on the phone in safe mode, you can determine if there is a program on the device due to which the system writes notifications about slow charging.

  1. Disconnect your phone.
  2. Hold down the power key until the company logo appears.
  3. Release the power button and at the same time hold down the volume down key.
  4. Do not release this button while the smartphone is loading in Safe Mode.

While in safe mode, you need to find the problematic application and remove it from the device memory.

What to do if it doesn’t work

If the above methods did not help, and you did not find external defects on the battery or USB port, the cause of the problems may be system failures.

Battery Calibration

You can solve the problem with battery calibration.

  1. Discharge the device completely (you can speed up the process by turning on or playing).
  2. Connect your smartphone to the charger and leave it connected for several hours.
  3. Wait until the display shows a notification that 100% charge is available. After that, disconnect the gadget from the power supply, simultaneously turning on the system.
  4. If after switching on the phone does not show 100% charge, then restart it.
  5. Discharge the phone completely again and reconnect it to power.

This will calibrate the battery. We do not recommend performing this action more than once every 23 months, as otherwise it may lead to battery wear.

Main reasons and solutions

There are a number of reasons why a gadget doesn’t charge well. The problem can be either a physical breakdown of the USB input, or a malfunctioning battery or incorrect system settings. Let’s look at each of the reasons for very slow charging.

The recommendations from the article are relevant for all models of Samsung Galaxy smartphones, including:

  • J4;
  • A5;
  • A7;
  • A10;
  • A50;
  • A51 and others.

Battery malfunction

Another common cause of slow charging is reduced battery life. According to statistics, a standard battery works correctly for 500 charge-discharge cycles for about 2 years. If this indicator is exceeded, the battery may take longer to gain charge and lose it faster.

This problem is especially relevant for owners of 34-year-old gadgets. But do not rush to draw conclusions, because the battery on the phone or tablet may malfunction after 11.5 years in case of intensive use.

We also recommend removing the back cover and inspecting the physical condition of the battery. If it has slight swelling or any other defects, the battery must be replaced with another.

Samsung Phone Is Charging Slowly

Charger problem

There may be 2 problems at once:

  • Using a non-original charger. Most users, when the factory charger breaks down, in order to save money, buy non-original chargers. Their current strength is often below the recommended values, so the gadget may charge slowly. In turn, chargers with excessive amperage can damage the battery;
  • Physical damage to the cable or adapter. Take a good look at the charger for damage. If normal inspection does not reveal any problems, it is necessary to check the functionality of the charger elements. To do this, connect another cord to the power adapter and put the gadget on charge. If necessary, perform a similar procedure with the charging cord.

Bad contact

It is quite common for the metal coating to have poor contact inside the USB port or on the charger cable. This can be either a defect due to the fault of the manufacturer or cable wear.

What should you do if your phone is charging slowly due to poor contact? Switch off the device and remove, if possible, the battery. After that, all contacts should be cleaned with something like a thin needle. This must be done very carefully and carefully. After cleaning, the battery must be replaced and the charger reconnected. This will often help restore normal charging.

Turn off your phone

Applications often run in the background. Their use significantly affects the duration of the charging process. For example, if a browser is running, Skype and something else, then the smartphone will take much longer to fully charge.

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

Battery Replacement

The life of a battery pack cannot last forever. After 4-5 years of use, its capacity is lost, which is why the phone is slowly charging. The more frequently the charging and discharging processes occur, the sooner the battery will deteriorate. If the battery stops working after just six months of use, then this is not normal. In this case, you should contact the seller.

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

Charging from the correct source

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

The problem may also be that an adapter is used from a completely different device, for example, from a headset, which is not intended for a phone at all. One often hears a complaint that Samsung phone is charging slowly. At the same time, users charge it using an adapter from other models. But all adapters supply different output voltages.

Updating software or downgrading to a previous version

Updates to your phone can negatively impact your phone’s battery life. This is especially true when the old model is updated to the new version of “Android”. Fresh models are usually optimized for updates.

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

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

The main safety

Do not charge the device near water or in extremely humid conditions, as well as in extremely hot conditions. You do not need to keep the device connected to electricity for too long. If it takes just three hours to charge, why leave it on recharge overnight? Because of this, over time, the phone charges slowly and discharges quickly.

If it becomes necessary to replace the wire or the charger itself, then you need to be careful, since cheap copies from Chinese manufacturers can be sources of danger. Recently, there has been an increasing number of cases of mobile phone fires due to poor-quality adapters.

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 in 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.

Feel free to take a brush, a toothpick and so on and clean the contacts, they very often become the cause (or bend the bar inside the USB connector), but you cannot do without service with the controller.

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).

over, 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 began to charge for too long, but why it quickly discharges, see here, and we go further.

Why does an android phone or smartphone take a long time to charge

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.

Of course, the best way to conserve battery life for longer is simply to turn off unnecessary services like Wi-Fi, Bluetooth and GPS when not in use.

In addition, there are several rules that need to be applied to the battery so that in a year the battery does not become suitable only for garbage, especially if you have one of the new, luxurious types, where the battery cannot be replaced without a specialist.

This was an introduction, and now I’ll tell you in order: why the phone began to charge for a very long time, quickly discharged and what to do then.

Summarizing the main reasons for a long phone charge

  • Bad contact of USB port and micro USB
  • Bad cable
  • Bad adapter (charger).
  • Bad battery of your phone or smartphone
  • Bad firmware (upgrade)
  • Many unnecessary processes are running along with charging

What to do when the phone started charging 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 which direction to move.

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

You can also calibrate the battery. As described here. Not always, but sometimes calibration solves the problem.

ATTENTION: wireless charging is available in some smartphones today, 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 discharge the battery. A fully discharged battery and unused for a long time should not be suddenly charged to full, this may endanger it.

REMEMBER: The increased temperature that accompanies the charging of the phone will reduce 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 has no way to replace the battery and the end of its life marks the end of the smartphone.

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

How long should an android phone or smartphone charge

There are a lot of phones, like smartphones, for example, samsung galaxy, Lenovo, xiaomi, meizu, asus, htc, lumiya and te-de., And their charging time is different.

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

Furthermore. 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 duration 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, maybe this is his norm

Blocked charging port on device

The phone constantly comes into contact with the fabric in your pockets or purse, so the port can become dusty over time and stop working normally. Pluggable charging can further clog the port, ruining a normal connection. Fortunately, the solution is simple: take a plastic toothpick or a new toothbrush and clean out the dirty port.

Defective or poor quality AC adapter of the charger

Another reason why your phone charges slowly is a faulty power adapter.

[attention type = yellow] Important information: the power adapter is the part of the charger that plugs into a power outlet. [/ attention]

The main reasons for the adapter malfunction are mechanical damage received:

  1. By bumps and falls
  2. Electricity surges and burnout of microcircuits and wires.

Another reason why the phone is charging slowly is the incompatibility of the AC adapter with the smartphone battery. In order to check compatibility, you need to check the parameters of the adapter and battery adapters as shown in the figure, if the parameters differ from each other, replace the adapter.

Insufficient power supply

If you are using a computer to charge your phone, expect to take longer to charge the device. This also applies to the USB 3.0 connector with an output power of up to 9A (USB 2.0 generally has 5mA).

If the cable is damaged, it will charge very, very weakly, as already mentioned above. The use of wireless chargers is no exception. On the one hand, it’s really cool when you can put the phone on the module and it will start charging, but on the other hand, you will lose in charging speed anyway.

Damaged USB charger cable

Charger damage is the most common cause of long charging times. The thing is that in the process of careless use, the USB cable receives mechanical damage to the connectors and wires, which naturally affects the charging properties of the device.

The solution to the problem is visual inspection USB cable or smartphone charger for damage. We recommend that you pay attention to the connector and to the fold, this is where the problem most likely lies.

Most modern processors in devices support fast charging. If you notice that your friends have similar phones charging faster, then try updating your Android version to the latest available.

1. Remove debris, dust and grains of sand

If you do not part with your smartphone for a minute, carry it in your jeans pocket and drag it to the sea, then sooner or later so much garbage will accumulate in the charging socket of the gadget that it will completely refuse to charge. Therefore, the first step is to visually inspect the USB port. Then blow it with a can of compressed air and gently brush with the bristles of a hard toothbrush.

3. Replace cable

The next weak link to check is the USB cable. Their lives are often full of trials and hardships, so it is not surprising that some of them may die without any warning. The easiest way to check this malfunction is to take a known working cable from another device and connect it to your gadget. If the problem persists, then go to the next step.

4. Test the power adapter

The charger is also a frequent source of problems. We are talking about the very small box that plugs into an outlet. First of all, touch it to check the temperature. An adapter that is too hot or too cold can be an indirect sign of failure. Make sure the cable connection socket is intact and clean it if necessary. Try to find a different power adapter that suits your specifications.

2. Clean the contacts of the USB port from oxidation

Sometimes the device does not charge due to oxidation of the contacts. This happens especially often if the smartphone has not been used for a long time or is operated in unfavorable climatic conditions. In this case, cleaning the contacts with a toothbrush soaked in alcohol, or even a fine needle, can help you out. Do not forget to first turn off the smartphone and remove the battery from it, and perform the operation itself as carefully as possible.

5. Buy a new battery

What to do if your smartphone won’t charge

So, at one not the happiest moment you put your smartphone on charge, but something went wrong. Instead of gratefully winking at you with the indicator and starting to absorb energy, your pet does not show any signs of life. What happened? In this article we will try to figure it out.
