Fast charging 2. Turbo charging for smartphones: how Quick Charge technology works

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 the Xiaomi brand, solved this problem when they added the function Quick Charge– ability to quickly charge your phone.

What it is

Xiaomi Quick Charge– the ability of Xiaomi smartphones to charge the battery many times faster than normal charging, reaching the 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, maximum power will be absorbed at the beginning of the power supply, 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 receives the necessary charge of energy faster.

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,” special controllers began to be added to the motherboard, which 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 based on 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 supply 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.

A similar technology to INOV is 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 the new firmware version supported Quick Charge 3.0, since when the phone was charging, a saying “Fast charging” appeared. 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 have this feature 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 the opposite direction - it absorbs battery power 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 the phone in this case is 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 an original Xiaomi power supply. Don't forget to also find the necessary data about power, current and voltage.
Not updated firmware. Some Xiaomi smartphone models, even those with the ability to charge the phone using Quick Charge, must be updated to the 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 while powered (especially excessively) 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.

Qualcomm Quick Charge is a technology from a well-known manufacturer of mobile processors that allows you to speed up charging your gadget’s battery. If you've recently purchased a new smartphone, there's a good chance 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 Qualcomm's first technologies, which the company describes as a "full suite of power management technologies" for charging 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 function properly. Since almost every new smartphone that offers Quick Charge 2.0 ships 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 the charging of 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 designed to regulate power and prevent high voltage and current from damaging your smartphone battery.

The biggest question surrounding this technology is the issue of 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 higher charging rates 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 computational algorithm that allows a device to determine the level of power it needs at a given 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 backward 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

First introduced with a flagship processor, QC 4.0 promises faster charging speeds 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 ditch non-standard USB-C chargers like Quick Charge and stick with 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.

(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 a charger with a specified current of 2A is 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 higher power. Thanks to this, they charge much faster.

Why doesn't my phone 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 of the 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.

In this article we will talk about a fairly new technology - “Fast charging of a smartphone”. All the advantages and disadvantages will be described, and we will also try to figure out whether this development is necessary for the convenience of consumers.

It is very difficult to imagine today without a smartphone and other modern gadgets. Every day the market is replenished with new models that are much more modern and more powerful than their predecessors. Smartphone screens are becoming larger and brighter, processors are becoming more productive and efficient, and RAM capacity is growing. All this consumes a large amount of energy, and the more intensively you use your smartphone, the faster the battery drains. Nowadays, only lithium batteries with a small capacity, but very reliable and durable, are mainly used. Manufacturers are fighting for their place in the market, so they are striving to reduce the charging time of the phone and make their devices more autonomous.

What is fast charging?

Let's take a closer look at how the fast charging process itself occurs. If we take a regular charger and look at the marking numbers on the case, we will see 5V/1A. The inscription means that this charger produces a maximum voltage of 5 volts and a current of 1 ampere. Fast charging is capable of delivering 5V/2A. This means that a smartphone with this feature can be charged about 40% faster.

The smart controller, which processes the incoming current, is not only built into the memory, but also into the smartphone processor itself. Fast charging often requires a cable that has better throughput.

Is fast charging safe for your phone?

But consumers are not particularly concerned about how this technology works; one question is important to them - “Is fast charging harmful for themselves and for the smartphone?” No one can give a definite answer, but many studies have been conducted, the results of which indicate 100% safety.

Lithium-ion and lithium polymer batteries, in principle, there is no difference with what current and voltage the process will take place. The most dangerous factor for integrity and service life is temperature. Conventional smartphone batteries are designed for 2000-3000 full discharge and charge cycles. If you allow the device to overheat, this has a detrimental effect on the battery and significantly reduces its capacity, which means it shortens its operating time. The main thing that experts do not recommend doing is purchasing low-quality, cheap memory devices.

Perhaps the most basic rules for the safe use of fast charging are:

Do not leave an infected smartphone unattended for a long time;
Do not cover your mobile device with pillows, blankets, or other fabrics;
Do not overload the processor and RAM while charging;
Do not use fast charging if the smartphone case or battery has cracks or other defects;
Use only original charger and high-quality cable.

A variety of fast charging technologies for smartphones

Quick Charge from Qualcomm;
Pump Express from Mediatek;
VOOC Flash Charge.

The most unfamiliar to us was VOOC Flash Charge. It is less common on the market, but, according to world experts, it provides the most gentle charging of a smartphone. It is also the fastest, but it can only be used with OPPO devices. It can fill a battery with a capacity of 2500-3000 amperes in twenty minutes. OPPO releases its own development called VOOK FLACH CHARGING, which is superior to many others. It has 5V/4.5v characteristics. But ordinary batteries are not able to withstand such current, so OPPO introduced a proprietary battery that has 8 contacts instead of three.

Qualcomm is the leader in the field

In general, the first fast charging was introduced by Qualcomm, called Quick Charge 1.0. It was first introduced in smartphones Samsung, Nexus, Nokia. Qualcomm's Quick Charge has captured most of the charger market. In just a few years it has been practically perfected. More than half of smartphone manufacturers cooperate with this company and actively use the technology in almost all of their gadgets. Even Samsung, which has long been the leader in the smartphone market, with its own developments, often uses technologies from Qualcomm.

The first fast charging appeared in 2013 and with each release of subsequent versions, it became smarter, faster and more reliable. This technology is introduced into a smartphone together with the chip, or through a separate chip. A year later, the company introduced a more powerful and improved Quick charge 2.0, which is capable of charging a battery with a current of 3 amperes. This implies a reduction in time to full charge by 70%.

And just recently, Qualcomm released a new charger with Quick charge 3.0. No, it does not charge a smartphone with a current of 3 amperes, it selects the optimal current for faster charging of absolutely any phone. The 3rd generation of technology from Qualcomm became phenomenal, as the developers did not try to speed up charging, but tried to reduce the amount of energy consumed, thereby preventing the generation of excess heat.

Then iKnow technology appeared. It flawlessly adjusted to any battery and any device. The smartphone “communicates” with the charger through it and finds the most optimal voltage. Now the company is preparing to release the smartest and fastest charging version 4.0. There are already several degrees of security here. There will even be a system implemented that will check the cable for damage.

The future of device charging

In conclusion, I would like to talk about the future of our gadgets and their power supply. Of course, time does not stand still and technology moves forward much faster than humans. In the near future, they are going to introduce graphene batteries, which will take a few minutes to fully charge. It is also quite possible that batteries containing radioactive elements will appear. They do not need to be recharged at all, just after a couple of years you will need to replace the old battery with a new one. We will figure out how safe and effective the technologies will be only after they enter the market.

A phone that goes off at the wrong time is the cause of nervous breakdown and subsequent protracted depression for more than one thousand people. Even if there is no important conversation, a dead mobile friend is still frustrating. And if you urgently need to talk, even throw yourself off the bridge. But not everything is so gloomy - there are many options on how to bring your electronic assistant back to life. This is a battery adapter, a power bank, and a “fast” adapter with Quick Charge support. It is the last option that I would like to discuss.

The fact is that for several years Qualcomm has been producing chips that are compatible with fast charging technology. The technology itself, which is now widespread, is called Quick Charge 2.0 - its support is provided either by using a separate chip in the system or a compatible Snapdragon chip. According to the developers, this technology speeds up charging the device's battery by up to 75%.

What is this, fast battery charging?

The advantages of this type of charging can be appreciated by watching this video (from Qualcomm, yes):

In the first few minutes, smartphones compatible with Quick Charge 2.0 are charged for several hours of work, so there is no problem for the user at all: he ran into a cafe or plugged into an outlet anywhere, waited a few minutes, ran away with a phone that is capable of working the remaining part of the day.

Currently compatible with this technology are Motorola DROID Turbo, Nexus 6, Samsung Galaxy Note Edge, Samsung Galaxy Note 4, HTC Desire EYE, HTC One remix, HTC One (M8), Motorola Moto X (2014), Sony Xperia Z3 Tablet Compact, Sony Xperia Z3 Compact, Sony Xperia Z3, Sony Xperia Z2 Tablet and some other devices.

And yes, the charger must be appropriate.

Qualcomm is currently developing Quick Charge 3.0. Charge 3.0 is backward compatible with previous standards, plus added support for USB Type-C. Previous standards supported a certain operating voltage range - 5V, 9V, 12V and 20V, but now an option is being implemented where the voltage can be anything, from 3.6V to 20V, with an interval of 0.2V.

How it works?

Each phone or tablet is designed for a certain current and voltage. This is both good and bad. The good thing is that the phone is its own protection, the bad thing is that you won’t be able to charge a regular phone using more current.

Fast charging is a little different.

Such adapters, as it were, widen the “doorway” and provide faster charging of the device, allowing the device to accept more voltage and current. For example, if old devices supported 5V and 1A, then new gadgets work with 9V and 2A (this is an example, the values may be higher).

If you connect Quick Charge to an old device, nothing bad will happen, the device will not burn out, but will charge at the same rate. So here you need both a smartphone (or tablet) and a charger that supports the Qick Charge standard.

Does fast charging harm the battery?

Many users believe that the faster you charge the battery, the more it reduces battery life. Slow charging, on the contrary, has a beneficial effect on the health of the battery without damaging it.

However, this is not entirely true. Back in 2014, Californian scientists conducted a study according to which fast charging does not harm the battery at all.

During the study, scientists found that with both fast and slow charging, the batteries were charged evenly and all charged particles were used. Over time, both groups' batteries performed as well as at the very beginning of the experiment.

What are the fast charging options?

There are quite a lot of them, there is no point in listing them all, we will try to mention only the most successful, in our opinion, chargers and powerbanks.

The chargers listed below have another advantage - AIPower technology, which automatically determines the input characteristics of a mobile gadget. For “smart” charging of devices via AIPower, a built-in TI (Texas Instrument) microchip is used. This is done so that a device that does not support Quick Charge is charged as efficiently as possible, with the optimal voltage and current that the smartphone or tablet supports.

An ideal option for fast charging is a Powerbank, which supports both Qualcomm Quick Charge and AIPower technology.

Aukey PB-T1

The device capacity is 10400 mAh, which is enough for several full charges of modern smartphones. There is only one USB port, with support for Qualcomm fast charging technology.

If the device does not support fast charging, no problem - it can be charged using Aukey PB-T1 in normal mode, but with maximum efficiency (maximum output current - 2.1 A in this case).

The device body is made of anodized aluminum, so it is not so easy to damage the external battery.

Characteristics

Model: PB-T1
Technologies: Qualcomm Quick Charge 2.0
Capacity: 10400mAh
Number of USB ports: 1
Input current: DC 5V/2.1A, 9V/1.8A

You can buy this universal charger at.

There are other options, both just chargers and powerbanks.

Aukey PA-T1: Charger with five USB ports at once, allowing you to charge five mobile devices. One of the ports supports Qualcomm Quick Charge 2.0. protects devices from power surges, short circuits and other possible problems.

If you don’t need to charge five devices at once, you can choose a simpler option - with three USB ports, one of which is smart. Well, with just one USB port, supporting Quick Charge.

For the motorist it is suitable with two ports, one of which is “fast”.

TechMatte: This is another manufacturer of Powerbanks with Qick Charge function. The capacity is 5600 mAh, plus there are two ports that allow you to charge two mobile devices at once.
TechMatte CHOE: will allow you to charge an entire plane, the capacity here is 15600 mAh, there are two outputs. Tablet, phone, smartphone - you can charge everything.

Let me remind you that if your phone is not on the list, then it can also be charged with “high-speed” charging, nothing will burn or explode. It’s just that the charging time for a phone without Quick Charge support using high-speed charging will be normal, the same as when charging the phone with its own adapter.
