Another common cause of slow charging is reduced battery life. According to statistics, a standard battery works correctly for 500 charge-discharge cycles. 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 3-4-year-old gadgets. But do not rush to draw conclusions, because the battery on the phone or tablet may malfunction after 1-1.5 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.
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:
- A51 and others.
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.
You can solve the problem with battery calibration.
Discharge the device completely (you can speed up the process by turning on or playing).
This will calibrate the battery. We do not recommend performing this action more than once every 2-3 months, as otherwise it can lead to battery wear.
Dirty USB input or plug
The first thing to do is inspect your smartphone’s USB port for contamination. If there are particles of dust or other debris on the contacts, clean them:
- First, blow out the USB connector of your smartphone well (it is best to do this with a compressed air cylinder);
- Then use a soft-bristled brush to clean the connector and blow again.
Repeat the same procedure with the plug from the charger if it is also dirty.
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.
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.
Dust and debris in the charging port
Many people carry their gadgets in their jeans pockets, and they contain small fibers that can cause the phone to charge slowly. Masters very often come across just such an incident. What if fibers or dust gets caught in the connector? It can be brought back to normal by blowing compressed air from a can. You can use a powerful cold air dryer or a compressor. After cleaning, the phone starts charging normally.
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.
Replacing the cable
In the whole charger, the most fragile part is the cable. Due to constant bending, it quickly breaks down, as a result of which the phone charges very slowly. What to do? The easiest way to diagnose a damaged cable is to temporarily replace it with another one. In the event that the other cable with the device works as expected, then the original wire is faulty. If not, then the reason is not in him.
Safety is key
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.
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.
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 a few 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.
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.
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 can’t do without a 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.
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 can charge faster than a new one. A paradox, but a fact.
You can also calibrate the battery. How. 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 could put it at risk.
Remember: The increased temperature that accompanies the charging of the phone will reduce the life of the battery and other electronic components.
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
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. 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. Perhaps this is his norm
There may also be problems when connecting the phone via the charger. For example, a broken or clogged socket on a mobile device. It can be blown out or lightly cleaned and straightened by yourself. The main thing is not to overdo it.
Another possible problem is oxidation or contamination of the contacts on the battery. You can clean them with a toothpick. The main thing is also not to press too much, otherwise the result will be sad.
This can also include problems with the wire: bends, kinks, and also if a non-native wire of a smaller section is used. The fact is that the voltage of the incoming current depends on the diameter of the cable. Therefore, it is worth using only what is suitable for this particular model.
Which phones are prone to slow charging
By and large, all phones are affected by this problem. It doesn’t matter if they work under Android, IOS or Windows, nothing lasts forever and sooner or later any electronics will start to fail, glitch or break, especially under high load and frequent use.
It is worth noting that smartphones with large capacious batteries suffer most from this, that is, brands such as Huawei, Xiaomi, Meizu, Honor, Lenovo, Asus and LG will be the first at risk. At the same time, iPhones, Samsung, HTC, Sony Xperia and Nokia are less susceptible to this disease, but this does not mean that nothing will happen to them.
Now let’s deal with the “stuffing” of the smartphone. A modern mobile device is not just a phone, but also a means for watching movies, listening to music, playing games, communicating and accessing the Internet. You can download and install many programs and applications on your gadget, many of which are very resource-intensive.
Over, energy is spent not only by those applications that you use right now, but also those that are in the background. Always disable all programs and applications after using them. If, while charging, several of these work in the background, then you will have to wait much longer until the battery is “saturated”.
Failed software update
The smartphone may start to charge poorly due to poor quality firmware. If you recently updated the software of your smartphone, then it is quite possible that this is the problem.
In this case, you can either wait for new patched updates, or roll back to the previous working software version. As a last resort, you can reset all settings to factory settings.
The first thing to pay attention to is the health of the adapter. Its breakdowns (both full and partial) can be caused by shocks, falls, kinks and pinching of the cable. Maybe one wire goes off in it, but this already affects the charging speed.
Also, the process will take too long if the adapter contacts are oxidized or dirty. It is also possible that you are using a “non-native” charger, and its power is much lower than what is required. In this case, it is worth trying to charge the smartphone using another suitable adapter. If everything worked out, then this is the problem.
How to solve it? Oxidized or contaminated contacts can be cleaned by yourself or by contacting the salon, in other cases the charger will have to be changed.
Any battery will fail over time. As it ages, the phone will have a poorer charge and take longer to replenish. Battery life. 500 full discharge-charge cycles, usually in 2-3 years.
First, it’s worth checking the battery capacity and understanding what resource is left. If significantly less, then all that remains is to replace the battery with a new one of a similar model.
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:
By bumps and falls
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.
Phone takes too long to charge. 10 main reasons
There can be many reasons why the phone is charging slowly, from the appearance of a defect in the USB cable of the charger, to the deterioration of the battery. Let’s talk about these reasons in a little more detail and so the first reason is damage to the USB cable of the charger.
Why did the phone take a very long time to charge
Why does the phone take so long to charge? This problem is relevant for the owners of every, if not the third, then the fifth smartphone owner. The problem of slow charging affects almost any phone model, be it a fancy Iphone X or a budget Fly or Alcatel. In today’s article, I would like to tell you about 10 possible reasons for slow smartphone charging and give diagnostic recommendations that will help solve this problem.
Phone takes too long to charge. 10 main reasons
Factory defect or software failure
After purchase, the phone should be properly charged. To do this, turn off the device and charge it for 15 hours. Try not to completely discharge the battery, only in this case it will last you longer.
Complete wear of the battery
The deterioration of the battery is also a fairly common reason for the slow charging of the smartphone. This malfunction is manifested not in new phones, but in models that have served you for a little over a year, and this is quite normal.
[attention type = yellow] Perhaps you did not know that a standard phone battery with a volume of 2 to 4 thousand mAh is designed for a little over 1000 full charges, after which its natural wear and tear begins. [/ attention]
There are two simple ways to identify battery wear:
If any faults are found, it is recommended to replace the old battery with a new one. Otherwise, it can lead to disastrous consequences. There have even been cases of battery explosion inside a smartphone while charging.
2. Clean the charging port from dust and third-party fibers
Do you keep your phone in your jeans pocket? If so, then fibers may be the culprit: we have already lost count of how many times the fibers in our clothes were the cause of faulty charging.
You can also normalize the charging connector by blowing compressed air.
Why the device won’t charge
Problems arise to one degree or another. Either the phone doesn’t want to charge at all when it’s plugged in, or the process is too slow. Here are some solutions.
9. Try turning it off
Using heavy applications while charging will affect the duration of the charging process. For example, if you are chatting on Skype or playing games, the device will take longer to charge.
Therefore, put the device on charging in the off state or in airplane mode.
What to do if your phone won’t charge properly
If your phone‘s battery isn’t charging properly, don’t assume that the battery or charging may be the only problem. Based on personal experience, the problem and the solution can be much easier than you think. If your smartphone or tablet is charging poorly or not charging at all, then check out 10 ways to fix these problems.
6. Replace the battery
Battery life does not last forever and after several years of use it loses its capacity. The more often you charge and discharge it, the more likely it will deteriorate. Of course, if the battery stops working after six months of use, then you need to contact the seller for a warranty.
Some defective batteries can be easily identified by their appearance. If it is swollen, then it should be replaced immediately.
3. Try a different cable
The most fragile part of the charger is the cable. He constantly bends, which can damage him over time.
The easiest way to diagnose a damaged cable is to take another one and see if it works properly with your device. If so, you know the original charger wire is faulty. If not, then you need to look for a solution further.
