No matter how good a smartphone is, it is powerless when the battery runs out.And as the smartphone gets older, the charging speed becomes slower.
Today, let's talk about charging smartphones.
After explaining how to charge the smartphone currently on the market, we will also introduce the reason why old smartphones are delayed and how to deal with them.
The smartphone always has a battery, and all batteries supply power to the smartphone in the same way.
Cell batteries (single batteries) have two electrodes, plus and minus, and contain electrolytic solution.When a cell battery is used, the ions are formed by electrodes, and the electrons flow toward the negative pole, so the charge is released.
In non -rechargeable batteries, these chemical reactions are limited to one time.
The rechargeable lithium -ion battery used for the smartphone causes a "reverse" chemical reaction, so charging can absorb power by charging.
There are two ways to charge smartphones: charging that can be broadly divided into charging cables and wireless charging that does not use charging cables, each with advantages and disadvantages.
Same as other home appliances, the smartphone always comes with a charging cable.Until recently, these cables were almost the same.
For the last 10 years, for devices other than Apple, USB 3.0 Comes with a USB cable that supports architecture.
However, since 2012, Apple devices have been charged using their own computer buses and power connectors called Lightning.
In recent years, the speed of charging using the cable has been greatly improved by the technology of "quick charging".
This charging requires a newly developed USB Type-C connection.The quick charging specification depends on the manufacturer and device.
In most cases, the battery is charged a certain amount in 30 minutes.For example, a quick charging cable can charge up to 50 % of the iPhone battery in 30 minutes.

At the moment, the best advantage of charging using a charging cable is efficient.
Also, it cannot be ignored that many smartphone users are used to using charging cables.
The most disadvantage of charging cables is the cable.
The cable may be worn over time, and it doesn't look good if the cable is messed up.
Wireless charging of smartphones is becoming more and more popular, but there are many advantages and weaknesses.
Needless to say, wireless charging is unnecessary, and can be charged simply by placing a smartphone on a charging pad.
Wireless charging makes the device difficult to exhaust, so the cost can be reduced in the long run.In that sense, it may be more expensive to charge using a charging cable.
Another reason for smartphone users wants to charge wirelessly is convenient.Many charging pads on the market can charge multiple devices at the same time.

As of 2018, wireless charging is still inferior in terms of efficiency because the charging speed is still slower than charging using the cable.
However, most of the smartphones will last a full -day battery once fully charged, so the slow charging speed is not very concerned.There is no problem if you put your smartphone on the charging pad every night before going to bed.
On the other hand, wireless chargers tend to be uselessly hot, and there is a risk that smartphones will be overheated.
To prevent accidents, be sure to purchase a certified wireless charger.
If you buy a wireless charger, it will cost more than when charging the cable.
With this, you can understand the battery charging mechanism.
Next, it will move to the cause of slow charging speed of old smartphones.In most cases, one of the five causes should be applicable.
The most simple cause of the smartphone charging speed is that there is a problem with the charging cable or charging adapter, not the smartphone itself.
At home, USB cables are shared with their families and used for charging multiple devices, so the use of USB cables is high.
Sometimes the cable is dropped on the floor, bent, or stored in a place where the room temperature changes significantly, or even step on it with your feet.
So, first replace the cable and check if the charging speed returns normally.
Replace the charging adapter to see if there is a difference in the charging speed.
If you buy a new smartphone and keep using the same adapter as before, you may want to new the adapter.
Many people want to charge smartphones using a PC port, but this is not always the optimal charging method, but it depends on whether the number of years of PC and other PCs are used at the same time.
We recommend that you charge your smartphone as much as possible using the wall outlet.
In other words, use a charger that is inserted into the wall outlet as much as possible.Also, check the safety of the charger before using it.
Even if there is a problem with the smartphone charging port, the charging speed will be slow.
Make sure that the charging port is damaged or corroded or if there is no garbage.
Even if you know that there is no problem with the charging port, it is worth examining it because it can be excluded from the reason why the charging speed is slow.
When checking if there is a foreign substance in the charging port, use a flashlight and a loupe to look into the charging port.
If there is a lint or dust, remove the port with great care so that it will not be damaged.I use plastic toothpicks.
It is also recommended to apply a small and soft brush inside the port.
A smartphone that takes a long time to charge will run out of battery as soon as you use it.This may be due to an unauthorized and background app.
Both Android and iOS have tools to check the apps running in the background.
For Android, go from "Settings" to "Battery" and check the menu that indicates the battery consumption.
With an iPhone, open the "Settings" app and select "Battery" to see which app is the most consumed.
If you think that the battery is unnecessarily exhausted, delete the app to see if the battery duration and charging speed will be improved.
If the battery charging speed is slow even if you try all 1 to 3 above, you may want to replace the battery.
At the end of 2017, Apple was criticized for how to handle old iPhone batteries.
But that was why Apple did that.
Although it is an open secret in the smartphone industry, a lithium -ion battery is not forever used and can only be charged a limited number of times.
Therefore, the battery itself may be due to slow charging speed.
If you want to know more about the battery replacement of your smartphone, bring your smartphone to the official store.
Are you using your smartphone while charging?If so, that's why the charging speed of the smartphone is slow.
It is famous that apps such as Facebook will shorten the life of the smartphone battery.It is other than posting to SNS while charging smartphones.
At least don't use your smartphone while charging.
Normally, charging of a smartphone does not take that long.
If you think that the charging speed has been significantly slower, you may be able to solve it easily by referring to this article.
However, if you can't do anything, bring your device to the nearest official service center and have an expert look.
If you can't charge your Android smartphone at all, try this before contacting a troubleshooting expert.
