The samsung galaxy s4 phone takes a long time to charge. The phone is charging slowly: what to do? Summarizing the main reasons for a long phone charge

If the phone is charging slowly, there is no 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 the slow charging of the 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 can make your own smartphone work perfectly. In some cases, the mobile device not only does not charge well, 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 precisely 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 may be clogged. Dealing with this problem is easy enough. If the 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 fails, and under such circumstances, the smartphone takes an extremely long time to charge. 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 that sells accessories for mobile equipment and purchase a new cable there, provided that it is in it that the problem lies.

Garbage in the USB port

Another reason why the smartphone starts charging slowly is, of course, garbage in the port where the USB charging cable is inserted. The reason for getting garbage is extremely simple, and craftsmen who deal with the repair of mobile equipment often face this tricky issue. People carry their smartphones in their jeans pockets, because of this, small fibers get into the port, because of which the connector becomes clogged and the phone starts to charge slowly. You can deal with this problem even at home. It is necessary to take a powerful hair dryer and blow through this connector, in addition, you can use a compressor or compressed air from a special cylinder.

Adapter not working properly

Another reason why the smartphone starts charging for a long time is the adapter. Due to falls, various mechanical damage, the adapter sometimes fails. To check its 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. Pretty much anything 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 to discharge in almost an hour, it will take a long time to charge and there will be a bunch of various problems (shutdown in the cold, and so on). The only viable option in such a situation would be to just buy a new battery. If the battery began to behave incorrectly after six months of use, this is an abnormal case and then it is worth contacting the seller with claims.

Charging from the right source

Some users start charging their smartphone from different sources - these 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 provide very little power, and because of this, smartphones start charging for a long time.

Turn off your smartphone

At times, it is the reboot of your own device that helps to solve the problem, due to which the smartphone quickly sits down. All this is due solely to the fact that many background applications are open, because of which the purchased device is quickly discharged. Turning off the phone helps clear the RAM, thus closing the running tasks.

Software update

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

Why is my Android charging so slowly? Why is the battery draining too fast? 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 power. 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, twist, curl: all of these are not very good 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 won't hold up) and a thicker rubber braid 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, and gets clogged with dust. If the problem is in it, then you can try to clean the dust with a toothpick.

Your charger may be damaged. 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 a breakdown. Connect your phone to your computer via a USB cable. If it starts to charge, the problem is in the adapter. Go to any hardware store and get 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 another adapter. If the charge is still not going, there is a chance that the outlet itself is not working. You can try charging your phone from an outlet in another room.

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

Similarly, if you use wireless charging, you will get a rather slow charge. No one is saying that wireless charging is not cool, but speed will have to be sacrificed.

Old software

Slow charging is not only a hardware problem, but also a possible software problem. If the software crashes or is out of date, the phone also cannot consume power and, therefore, be charged.

Also, if your phone has a problem with the old charger after you have updated your gadget to a new 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 raging drain on battery, you might have some apps running in the background that are constantly eating up power. As a result, your phone charges much more slowly.

The easiest solution here is to clean up 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 see if your battery life and charging speed improve over the next few days.

If I had a dollar, every time people complain that the battery takes a long time to charge in an android smartphone, then I would not have much left to become a millionaire.

This is of course a joke, but such a problem exists. 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 that need to be applied to the battery so that in a year the battery does not become just garbage - especially if you have one of the new, plush 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 long should an Android phone or smartphone charge?

You can find out what is 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, lumia, etc., and they have different charging times.

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

Moreover. If the phone is turned off, it will also charge faster than 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’s battery takes a long time to charge, look at the battery capacity - maybe this is the norm for him

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 is of course in the battery itself.

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

All this undoubtedly affects the speed of charging 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 bent.

Another reason is the charger itself. Try something else 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 to another one - 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 here, and we go further.

Summarizing the main reasons for a long phone charge

• Poor contact between the USB port and micro USB
• Bad cable
• Bad adapter (charger).
• Bad phone or smartphone battery
• Bad firmware (upgrade)
• Along with charging, a lot of unnecessary processes are running

What to do when the phone starts charging for a long time

If you, for example, have 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 can determine which direction to move.

NOTE: An old used 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.

WARNING: wireless charging is available in some smartphones today, such as the Lumi 92, or the Samsung Galaxy S4, but it's better not to use it - it significantly reduces the life allotted to it.

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

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

How to prevent your phone from overcharging

Avoid full discharge. A partial charge is better than a full charge all the time. Do not expose the battery to high or low temperatures for extended periods.

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

Then don't be afraid to change. Contrary to what people may think, even on devices without a removable back cover, you can replace the battery, except that this may require you to take 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 allow you to charge your phone faster and keep it in good condition for longer.

Tips for avoiding long-term charging of your phone or smartphone

It's best not to charge your device at night - it can't "wake up" on its own to trigger an alarm.

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

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

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

If you depend on fast charging, use a short cable with thick strands. Current losses will be less. Be careful on hot days - do the work in a cool place. Beware of cheap chargers.

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

Mobile devices are not just called in this way. At present, 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 surveys where the most important metric was device uptime.

However, not only the operating time determines the mobility of the gadget, but also the charging speed. There are now many fast charging technologies that can charge your device up to 70 percent in just 30 minutes. However, some users may experience some difficulties with this. Smartphone charges 3-4 hours? We will try to find and fix the problem.

Before blaming everything on a faulty or another update to a more recent version of Android, try to first check the cable for external damage. The USB cable is not given much attention when it comes to its longevity, on the contrary, many manufacturers have begun to produce a protective coating of cables from organic substances, which leads to faster failure, by the way, Lightning is a good example of this.

Check to see if your cable has a broken protective coating, and it is likely that the cable has been in places with a very low temperature. In any case, the first step is to test it on another device. If everything works properly, go to the next step, otherwise, replace your USB cable with a new one.

Meanwhile, you should also check the USB port for external damage. In addition, it may corrode if the unit has been immersed in water.

Weak power source

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 transmits up to 2.5W (0.5A/5B), while USB 3.0 transmits up to 4.5W (0.9A/5B).

Faulty adapter

Evaluate the power adapter for external damage, but if no problems have been identified, check the adapter parameters: if the current is only 1 A, the device will charge more slowly than if it is about 1.5-2 A. However, it is worth remembering : Not every smartphone supports such indicators. Try to always use the standard adapter that comes with the kit. Meanwhile, some modern devices support Quick Charge, and as a rule, there is no QC adapter in the kit, you need to buy it separately.

Your smartphone is outdated

If you use the gadget for more than two years, you should not think that it will charge as quickly as modern devices in 2015 that support various fast charging technologies. Want to keep up with progress? You should buy yourself a new modern smartphone.

The battery has failed

Generally, battery life is very limited. 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 a 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 backlight of the display. Close running applications from the multitasking window, “kill” unnecessary processes, wakelocks, for this you can use Greenify or Wakelock Terminator, for example.
