Qualcomm Quick Charge - what it is and how fast charging technology works. Fast charging functions Qualcomm Quick Charge, MediaTek Pump Express and others Quick charge 3.0 backwards compatible

Home / Mobile devices

(Quick Charge), so users actively use this useful technology. QC allows you to quickly and efficiently charge your smartphone; in just an hour, the battery charge is 100% again. For our readers, we have prepared material that will help you learn everything about Quick Charge 3.0 and how it works.

Quick Charge

Qualcomm Technologies continues to introduce new innovations to the mobile device market. At one time, Quick Charge 1.0 technology clearly demonstrated that smartphones can charge 40% faster than with conventional charging.

A year later, QC 2.0 was introduced, allowing the device to be charged 75% faster. In addition, various accessories compatible with this technology were presented.

In 2015, Qualcomm Technologies continues to develop its industry. Quick Charge 3.0 charges even faster and more efficiently. By the end of 2017, Xiaomi has already released more than 10 smartphone models that support QC 3.0

With Quick Charge technology, a higher level of current is supplied to the battery, thus charging as quickly as possible.

For successful charging, the device and the charger itself must be compatible with the same voltage and current.

For example, if the phone supports a 9V/2A charger, but it charges with a 1A charger, the process will take much longer.

Another example if charger with the specified current strength of 2A will be used to charge a smartphone that supports a maximum of 0.7A, this will not make it charge faster.

The phone can also be charged faster if a similar charger is used, but with a higher current.

Note: products without a certificate are not guaranteed declared effectiveness.

How does Quick Charge technology work?

Quick Charge technology allows you to optimize the energy supply to your smartphone battery during the first stages of charging.

Thus, some phones can be charged up to 80% in just half an hour. However, in the final stages of charging, the energy transfer is not as high, regardless of which charging technology is used.

Consequently, the battery can be charged up to 50% in a short amount of time, but you will still have to wait more than an hour to fully charge the smartphone.

QC 3.0 charges mobile devices 4 times faster. Compared to QC 2, charging speed has increased by almost forty percent.

Qualcomm focuses consumers' attention not on increased charging speeds, but on increased efficiency. Thus, the main innovation in the technology is the INOV function, which is capable of intelligently selecting the required voltage, more accurately optimizing the power and charging time of a particular device.

Differences between QC 3.0 and previous versions

To understand the main differences between the latest version of quick charge technology and previous ones, just look at the table below:

After reviewing, we can conclude that due to the increased voltage, the charging time of devices decreased from version to version. The maximum power in the third version remained almost the same as in the second - 18 W. At the same time, low voltage batteries receive more high power. Thanks to this, they charge much faster.

Why doesn't my phone have support? fast charging? This is exactly the question most often asked by owners of smartphones that do not support Quick Charge. For example, owners of a new smartphone running stock Android would be very disappointed by the lack of Quick Charge in the device.

The problem is that Qualcomm's technology is proprietary. And its support depends on the model installed processor. These are the nuances that developers take into account when releasing a new smartphone.

According to the instructions from the Qualcomm website, they do not prohibit the use of certified adapters on phones without fast charging. Yes, your smartphone will charge properly, but you won't be able to experience all the benefits of Quick Charge when charging your device.

Conclusion

The Quick Change function is quite promising and in demand. The developers are not sitting idly by, but are improving it, complementing the 4th generation of fast charging technology with new functions.

Users will be pleasantly surprised by the new Xiaomi smartphones supporting Quick Change 4.0, the presentation of which is expected in the first quarter of 2018.

Fast charging (Quick Charge) is a technology that increases the standard USB specification voltage and current at the output of the power supply to speed up charging the battery of a phone or tablet. Fast charging modes vary depending on the technology. Fast charging support is implemented in smartphones and tablets Samsung Galaxy, ASUS ZenFone, Google NEXUS and a certain number of other devices.

As you know, a standard USB 2.0 port supports powering devices up to 2.5 W (5 V and 0.5 A). In turn, the USB 3.0 port can provide power to devices with a power of 4.5 W (5 V and 0.9 A). At one time, Apple set the trend for charging from more powerful power supplies - the first iPad generation required, that is, 5 V and 2 A. When connected to regular USB port iPad computer didn't even show that charging had started. Charging, of course, was going on, but so slowly that it was impossible to charge the tablet even in a whole day.

Today, most smartphones can charge from 5-watt USB chargers, and tablets can use up to 2.1 A from a 5-volt charger. How many Amperes to take from the USB port of the charger is decided by the battery controller of the smartphone or tablet, so it is quite safe to connect the smartphone to a 5 V / 2 A charger - the controller uses as much current as is needed for charging.

So, in order to quickly charge modern gadgets, such as a smartphone or tablet, well-known manufacturers mobile platforms developed special technologies.
Qualcomm has already presented the fourth version of the technology Quick Charge 4, and MediaTek, in turn, presented two specifications Pump Express and Pump Express Plus.

The point of these technologies is to charge the battery of a smartphone or tablet as quickly, efficiently and safely as possible. To support each technology, mobile device, including the battery controller, must be compatible with it. Of course, you need a certified charger that can “speak the same language” with the battery controller of your smartphone or tablet.

Each of these technologies uses the same techniques - either increasing the current, or increasing the voltage, or both. Qualcomm became a pioneer in fast charging - the technology was presented in February 2013 Quick Charge 1.0. Devices supporting this technology can be charged at 5 Volts and use 2 Amperes. As you can imagine, tablets with Quick Charge support began to charge as quickly as iPads, and smartphones - almost twice as fast as others.

Next generation Quick Charge 2.0 made it possible to use increased voltage for charging up to 12 volts. More precisely, for QC 2.0 you can choose from three fixed voltages: 5 V, 9 V and 12 V (optional, 20 V chargers are also available). At the same time, the maximum power of the power supply can reach 18 W.

Quick Charge 3.0 appeared in devices based on Qualcomm Snapdragon 820, 620, 618, 617, 430 and newer processors. It is characterized by increased efficiency and intelligence. A compatible charger can dynamically change voltage from 3.2 V to 20 V in 200 millivolt increments. The current strength also changes dynamically. Moreover, changes in the power supply configuration continue during the charging process - the current decreases as the battery is charged in order to save its resource. In particular, because of this, the last 20-30% of charging occurs noticeably slower. The power of Quick Charge 3.0 power supplies remains the same - 18 W maximum, but charges gadgets a little faster, due to better optimization process.

As you can see, the advantages of the technology are obvious - according to the manufacturer, in 30 minutes you can charge your smartphone by more than half. More precise figures are as follows: a 3300 mAh battery was charged to 60% in 30 minutes. Impressive result, isn't it? In addition, the manufacturer claims that Quick Charge 3.0 works twice as fast as the first generation Quick Charge, which is generally logical. We also note that all three generations of technology are backward compatible, that is, a power supply of any generation will be able to quickly charge a device of any generation. Of course, the first generation power supply will not be able to charge as quickly as a power supply that supports QC 3.0.

With the announcement of the Qualcomm Snapdragon 835 processor, information also appeared about Quick Charge 4.0. 20% faster and 30% more efficient. Capable of giving 5 hours of work in 5 minutes of charging.

Note that the technology implemented in chargers is not at all demanding on the type of cable - you can use regular cables USB Type micro B, USB Type C or cables with a proprietary connector from the gadget manufacturer. It should also be noted that fast charging is only fast up to approximately 80% charge. And it will take a long time to charge the battery to 100%, to avoid damage to the battery.

Regarding fast charging technologies MediaTek Pump Express and Pump Express Plus- Little is known about her. More precisely, there are very few smartphones and tablets, as well as chargers themselves, that support this technology. The essence does not change from this. Pump Express allows you to charge devices using a voltage of 3.6 - 5 Volts and with a charging current of no more than 2 Amps. That is, this technology is designed to compete with Quick Charge 1.0. In turn, Pump Express Plus allows you to use various voltages of 5 - 7 Volts, 9 Volts and 12 Volts, and the output current can reach 3 Amperes. True, MediaTek says nothing about 5 Volts and 3 Amps. But there is a mention of 9 V and 1.67 A (15 W), as well as the most powerful block power supply 12 V and 2 A (24 W).

* - The list is for informational purposes only. Exact list compatible devices no, details may appear.

There are other USB fast charging technologies, for example. The technology allows you to charge devices under a voltage of 9 Volts with a current of 2 Amps. An 18-watt charger, in particular, is included in the delivery of some ASUS ZenFone 2 smartphones.
At Samsung, similar technology for TOP smartphones Galaxy Note 4, Galaxy Note Edge, Galaxy S6, Galaxy S7, Galaxy S6 active, Galaxy S6 edge, Galaxy S7 edge, Galaxy S6 edge+ and Galaxy Note 5 named and released a special charger. It can produce a voltage of 5 or 9 Volts and a current of 2 or 1.67 Amps, respectively.

In general, given that the “normal” voltage for USB devices is 5 Volts, it looks quite logical when some smartphones that support USB fast charging technology are equipped with chargers with characteristics of 5 Volts and 3 Amperes. For example, such chargers can be found bundled with and from LG.

Knowing that there are a huge number of and, some of which are capable of delivering up to 2.4 Amps per USB port, it is difficult to convince yourself of the need to purchase expensive certified chargers. After all, it is obvious that smartphones and tablets that support fast charging technologies will independently take all the necessary and available charging current from the USB port, and accordingly, they can charge faster than from a standard charger with more modest characteristics. The conclusion, of course, is theoretical, and therefore does not claim to be the absolute truth.
We add that the specification of the new connector and cable assumes the ability to use a maximum current of 5 Amps per connector and 3 Amps per standard cable. In theory, at 20 Volts you can reach 100 W - excessive for the vast majority of smartphones and tablets. In practice, we will see the implementation of all kinds of fast charging functions (including those described above) using a standard USB Type C cable, as well as an expansion of the range of USB chargers with increased output current.

Hello everyone! It's time to introduce you to a good, inexpensive charger that supports the Quick Charge 3.0 fast charging protocol. Who is too lazy to read: the device is suitable, no problems were identified during operation.

Specifications:
- Input: 100-240V 50/60Hz 0.5A Max.
- Output: 5 V=3 A, 9 V=2 A, 12 V=1.5 A.
- Fast charging support: Qualcomm QC 2.0, QC3.
- Protection: from overvoltage, short circuit, overcurrent and temperature.
- Weight: 45 gr.

Appearance

The charger is supplied in a regular spare parts package. It is immediately obvious that the device is “no-name”, because there are no characteristic inscriptions on the packaging, there is no security code or address of the manufacturer.

The charger is made of snow-white, matte plastic. There are grooves on the sides for fingers to make it easier to remove it from the socket. Made with high quality, nothing to complain about.

To connect to the power network, a Euro plug, type CEE 7/16, is used. For residents of America (and not only) the seller has an option with a type A plug.

Located on the side edge text information with technical specifications.

At the top end there is a USB port with a green plastic insert. Below it there is an inscription with the name of the fast charging protocol qc 3.0. The cable stays in the socket well and does not dangle. There is no light indication of operation. In general, a standard charger, which many manufacturers sell for 7-10 bucks, making their own nameplate.

Device dimensions. For comparison, I placed an 18650 battery next to it.

Disassembly

We warm the body with a hairdryer, and then carefully halve it. We take out the “internals”. The contact of the Europlug with the board is carried out thanks to metal brackets, arched type. The installation of the elements was done quite well, traces of flux are minimal. The only thing that catches your eye is the absence of radiators.

On one side of the board.
ABS 210 bridge rectifier. Used in almost all chargers that I have disassembled.

On the other side.
MOSFET transistor 4N60G.

Schottky diode MBR20100CT. Next to USB port There is a chip labeled PT4U2K, which most likely controls the operation of Quick Charge.

Transistor optocoupler PC817B.

Testing

To begin with, as always, I checked the presence of “mind” in the charge. There is a voltage of 2.7 V on the data contacts, that is, Apple devices will be charged without problems with a current of up to 2.4 A. When connecting another smartphone, be it Samsung or LG, the voltage on D+ and D- changes, adapting to the device, providing it with maximum charge current.

Voltage without load. Everything is fine.

The device passed the QC 3.0 test, the voltage gradually rises in steps of 200 mV to 12 V, and then also smoothly decreases down to 3.7 V.

The previous Quick Charge 2.0 is also available.

Then I checked the maximum current output in various modes.
In 5V mode.
The port was able to supply 4 A without much voltage drop. Unfortunately, this is the limit for my load, but I think this is quite enough to understand that charging is “not a bad idea.”

In 9 V mode.
The maximum current output was 2.73 A.

In 12 V mode.
The maximum current output was 2.02 A.

Stability test.
I tested it in the modes stated by the manufacturer to make sure that the charger works normally for a long time. Test time ≈ 45 minutes.
In 5 V/3 A mode, the device heated up to 61 degrees. The voltage dropped to 4.92 V during the test.

In 9 V/2 A mode, the device heated up to 60 degrees. The voltage rose to 9.27 V.

In 12 V/1.5 A mode, the device heated up to 60 degrees. The voltage rose to 12.49 V.

Result:

A decent charger that has good assembly, declared electrical characteristics and low cost.

Qualcomm Quick Charge- this is technology from a well-known manufacturer mobile processors, which allows you to speed up charging your gadget's battery. If you have recently purchased new smartphone, chances are good that the included power supply already comes with QC and is capable of charging your phone significantly faster than any other chargers you have in your arsenal. This little piece of magic is called Quick Charge by , and it's a two-step process that promises to charge your phone quickly and, most importantly, without sacrificing battery life.

Quick Charge 2.0

Quick Charge 2.0 is one of the first technologies from Qualcomm, which the company describes as " full set power management technologies" to charge your device using a regular micro USB cable. For such charging to work, the company puts forward two main requirements for Quick Charge 2.0:

smartphone or tablet with a Snapdragon processor on board
power supply with support for Quick Charge 2.0

Because this is a two-step process, both the power supply and the phone or tablet must be licensed and certified by Qualcomm to proper operation. Since almost every new smartphone that offers Quick Charge 2.0 comes with a compatible power supply, users almost always have what they need to take advantage of this technology out of the box.

Manufacturer pays for license to use QC

There are also some smartphones on sale with Snapdragon processors, where the manufacturer refused to pay for the license to use Quick Charge 2.0. A striking example of this is OnePlus and their OnePlus 3T smartphone, which uses its own fast charging Dash Charge. So be sure to check the specifications on your next device to be absolutely sure it supports QC.

The main part of the technology is hidden, of course, in the power supply; a smaller part falls on the processor, namely voltage and current control. Today, almost all chargers offer 10 watts of power, or 5V/2A, out of the box, which significantly speeds up charging for most smartphones and tablets. Qualcomm's Quick Charge technology allows for multiple charging options for your device, and they come in different shapes and sizes.

The technology works as follows: it recognizes the current battery status and intelligently regulates power to your device. As a result, your phone won't charge as quickly from 70 to 100 percent as it will from 0 to 60 percent. That's why every Quick Charge update boasts the ability to quickly go from 0% to 50% charge in just 30 minutes. This is done in order to regulate power and not allow high voltage and the current will ruin the battery of your smartphone.

The biggest question with this technology is a matter of time. battery life, in particular, Does Quick Charge affect battery life? in your device. Typically, slower charging allows your battery to function for a longer time than fast charging the battery. A side effect of the higher charge rate is that the case will heat up, and high temperatures almost always have a negative effect on electronics. However, there is no evidence yet to support battery degradation associated with continuous use of Qualcomm QC fast charging.

Considering that the average life of a smartphone is 1.5-2 years, during this time users will not have time to damage the smartphone’s battery with fast charging. At the very least, the wear on the battery will be the same as when using a regular “slow” charging block.

At the end of 2015, Qualcomm released updated Quick Charge 3.0 technology. It uses the same basic principles as Quick Charge 2.0, but now you'll be able to charge your phones even faster with QC 3.0.

In lab tests using a 2750 mAh battery, the Quick Charge 3.0 device charged the battery from 0% to 80% in 35 minutes, while the non-Quick Charge 3.0 device with a regular charger (5V/1A) reached only 12% charge in those same 35 minutes.

Charging speed from 0% to 80% in 35 minutes

This technology works on what Qualcomm calls Intelligent Negotiation for Optimum Voltage (INOV). This is a new computing algorithm that allows a device to determine the level of power it needs in at the moment time. This means that charging always operates at the most efficient and optimized rate of power transfer to the battery. Support for a wider voltage range (200mV from 3.6V to 20V) means your smartphone can dynamically adjust to one of dozens of charge levels.

Quick Charge 3.0 is implemented in the same way as previous versions, and all devices with QC 3.0 are fully backwards compatible with gadgets with Quick Charge 2.0 and Quick Charge 1.0 on board. QC 3.0 supports USB Type-A, USB Type-C and micro USB. Manufacturers can easily use QC 3.0 for a wide range of chargers, not only classic chargers, but also power banks and other equipment.

Quick Charge 4.0

QC 4.0 first appeared with a flagship processor, this technology promises even more high speed charging than ever before. Quick Charge 4.0 has three key improvements:

20% faster than QC 3.0
30% more efficient than Quick Charge 3
operates at approximately 5 degrees Celsius

Additional "battery saving" features will extend the life of the phone's battery, and QC 4.0 is fully compatible with USB-PD USB (USB-PD) (Power Delivery). But the last interesting feature on our list is perhaps the most important. In its latest Android compatibility document, Google strongly recommended that manufacturers eliminate non-standard chargers. USB-C devices, such as Quick Charge, and adhere to the USB-PD specification. With QC 4.0, not only can you extend your phone's battery life to up to five hours with just five minutes of charging, but you won't have to worry about compatibility between the charging brick and your smartphone.

QC 4.0 hardly heats up the case

QC 4.0 also includes the latest iteration of Qualcomm's power management algorithm, Intelligent Negotiation for Optimum Voltage (INOV). This add-on is responsible for real-time temperature management, it will adjust the temperature while power is applied to ensure safe and efficient operation. The first devices with Quick Charge 4.0 on board are Xiaomi Mi6 and Samsung Galaxy S8 (version with SD 835 chip). More smartphones with QC 4.0 support will appear in the third quarter of 2017.

Taking a long time to charge your phone is a very common problem among users of modern gadgets. There is often not enough time to recharge, and the battery burns out at the most inopportune moment.

Fortunately, smartphone manufacturers, including Xiaomi brand, solved this problem when they added the function to the new features of their phones Quick Charge– ability to quickly charge your phone.

What is it

Xiaomi Quick Charge- opportunity Xiaomi smartphones Charge the battery many times faster than normal charging, reaching a full battery in almost 30 minutes.

Its main task is to fill the battery with the volume that will not damage it as quickly as possible.

How does Quick Charge work?

The operation of this option is based on the large consumption of current power during the power supply process itself (limit – 20W). If the battery is completely discharged, at the beginning of the power supply the maximum power will be absorbed, and less and less as the power supply progresses.

Current power according to the formula– product of current (I) and voltage (U). That is, by increasing the current power, either the voltage or the current increases, and in this situation the battery quickly receives the necessary charge of energy.

A visual explanation of this principle:

How did the creation of Quick Charge begin?

When the Quick Charge function was in its infancy, developers tried different methods to reduce the time it takes to recharge the battery. Originally, Quick Charge was based on increasing the current. The first power supplies had the ability to receive a current of 2A at a voltage of 5V. As a result, the required power was 10 watts.

But this method was unpromising, since subsequent work with the current required a change in the cross-section of the wire, and it was decided to increase the voltage instead of the current.

Since it was impossible to produce the maximum voltage “out of the blue,” motherboard They began to add special controllers that are capable of receiving voltage greater than the usual 5 Volts, converting it into the required battery charge.

Quick Charge technology versions and maximum power absorption

By transforming Xiaomi fast charging, the developers also increased its capabilities, that is, the consumed current power.

Characteristics and differences between Quick Charge versions

Today there are 4 lines of this technology, but for the most part the manufacturer Xiaomi uses only three:

Quick Charge 1.0– version presented in 2013. Literally immediately won consumer sympathy and was used in many phones. It allowed the device to be charged 40% faster than usual, which means that the phone could be half charged after 40-50 minutes. It was in almost every phone with a Snapdragon processor.
Quick Charge 2.0– an improved version of fast charging helped charge the gadget even faster. The charge was at half capacity after 30 minutes.
Quick Charge 3.0- very similar to the previous one, with the exception of a new significant function “INOV” - Intelligent Negotiation for Optimum Voltage - the most accurate selection of the voltage required for charging and monitoring the “well-being” of the gadget. After 20 minutes, the phone can be charged by 50%, and after half an hour - by 70%!
Quick Charge 4.0– version powered by the new Snapdragon 835 processor. Fills the battery halfway after 15 minutes.

In mid-2017, the manufacturer presented a new version from Qualcomm – Quick Charge 4+, which can charge 2750 mAh batteries by half in less than 15 minutes, and with a 5-minute charge the phone can last up to 5 hours.

INOV technology – Intelligent Negotiation for Optimum Voltage

INOV technology- this is the new ability of Quick Charge to establish a relationship with the phone during the power process - the unit receives the necessary data on the state of the battery, with the help of which it monitors the received power, current, voltage, and temperature of the smartphone.

Similar technology to INOV - Battery Saver Technologies.

Smartphones that support Xiaomi Quick Charge

Unfortunately, not all Xiaomi phones support the fast charging option.

Quick Charge Version 1.0:

Xiaomi Redmi Note Prime;

Quick Charge 2.0 version:

Xiaomi Redmi 5;
Xiaomi Redmi 4x;
Xiaomi Mi Note;
Almost the entire Mi line.

Quick Charge 3.0 version:

Mi Note 3;
Xiaomi Mi Mix 2;
Xiaomi Mi Mix;
Xiaomi Mi Max;
Xiaomi Mi Max 2;
Xiaomi Mi 6.

Quick Charge 4.0 version:

Already installed on: Xiaomi Mi 8;
Probably will be installed on: Xiaomi Mi 7, Mi Note 3 Plus, Mi 6 Plus.

Full list of models:

Some users of the Xiaomi a1 smartphone after updating the firmware to Android Oreo thought that in new version The firmware supports Quick Charge 3.0, since when the phone is charging, the saying “Fast charging” appears. However, this is a misconception. Testing attempts have proven the opposite, which indicates the absence of a fast charging function on the Xiaomi a1 phone.

If your phone model is not in the list, you will not be able to add/purchase Xiaomi Redmi fast charger.

How to enable fast charging on Xiaomi

In order to activate the fast charging function on a Xiaomi smartphone, you do not need to go into the settings or use the help of a PC.

Xiaomi phones either they have this opportunity right away or they don’t. Quick Charge is located in the power pack itself.

To make sure that your smartphone is equipped with this option, inspect the unit. It should contain data on current (A) and voltage (V). If these parameters, when multiplied, give a power above 10 Watts (while conventional chargers absorb only about 4.5 Watts), and the fast charging icon is visible, this is indeed a Xiaomi fast charging cable, and you are the happy owner of a smartphone with this function.

Is it worth using a power supply that has a fast charging function with regular phones?

If your smartphone is not in the above lists, it means it is not equipped to charge the battery in a short time. And an attempt to do this using a much earlier released phone with a special block Quick Charge can lead to overvoltage, fire, or damage to the gadget - it will simply stop turning on.

Does using this function affect the smartphone itself or the battery?

There are a lot of scary opinions about Quick Charge:

The fast charging option also works in reverse side– absorbs battery charge faster;
Damages the battery and causes it to wear out faster;
It is impossible or dangerous to charge your phone using Quick Charge if it is turned off.

All of the above does not have any substantiated arguments and are myths. Moreover, a huge number of people are working on the development of fast charging functions, and many tests and experiments have been carried out to prove that the phone and its battery are completely safe when using Quick Charge or using other innovations in this industry.

The only thing you should avoid when recharging your phone in in this case– thick, dense cases and any objects located on the phone itself (pillows, clothes, blankets), as this can also lead to excessive heating or overvoltage.

Fast charging function does not work

There are several reasons why Quick Charge refuses to work:

First of all, the phone will not charge when relying on this function due to the initial lack of such an option. If this option is important to you, when purchasing a phone, check with your consultant in advance about its availability in the selected model. As mentioned earlier, simply purchasing a charger with this function and putting it into use does not bring anything good.
If your phone is included in the list of models with Quick Charge, but fast charging still does not occur, make sure that you are using original block Xiaomi power supply. Don't forget to also find the necessary data about power, current and voltage.
Not updated firmware. On some Xiaomi smartphone models, even those endowed with the ability to charge the phone using Quick Charge, the software must be updated to latest version.
The fast charging option may be disabled if the phone is fully used while powered, or if there are foreign objects on it;
Problems with the firmware or with the phone itself.

What not to do while charging

Many of the myths mentioned above are born from the incorrect use of the fast charging function.

To avoid experiencing similar battery failures in the future, you need to be able to properly handle Quick Charge technology.

When using this function, pay attention to the following:

Using the phone during power supply (especially excessive use) can lead to overheating, as mentioned earlier, and disrupt the joint operation of the phone with the power supply;
Charging the phone only at maximum power - if you constantly charge the phone only at the expense of this very maximum power, which arrives in a fairly short time, and by half, the operation of the fast charging function may also be disrupted and will soon wear out, so resort to using this function only if necessary.
