We charge quickly: Quick Charge, mCharge, Super Charge fast charging technologies. Qualcomm Quick Charge, MediaTek Pump Express and other Qualcomm quick charge 2.0 supported devices

The operating time of a modern smartphone is a stumbling block for all manufacturers. You can endlessly increase the power of the chipset, display resolution, use the coolest camera, but all these advantages do not matter if the device will live from charging for only half a day. The obvious solution is to increase the capacity and quality of batteries, but the first is limited by the smartphone case, and the second - modern technologies.

As a result, companies came up with a third, no less elegant way out of this situation: if you can’t come up with a smartphone that will last a week on battery power, then you can make it charge so quickly that the battery life ceases to play a decisive role.

About technology

The main factor affecting the rate of battery charge is the current supplied by the power source. The higher the current, the faster your smartphone will charge. However, you cannot endlessly and thoughtlessly raise the current strength, as this will entail the need to adapt the rest of the smartphone components involved in charging. In addition, increasing the current will increase the heating of the case.

Therefore, Qualcomm decided to charge smartphones not with current, but with higher voltage. To do this, the power was increased to 10 W, the current to 2 A, and the voltage was 5 V. The charging speed with this approach increased by 40%. In the second generation of Quick Charge, they learned to use voltages of 9 and 12 V, which made it possible to increase the power to 36 W and slightly increase the charging speed.

The main difference between Quick Charge 3.0 is a significant reduction in the heating of the case and charger. This is achieved thanks to the Intelligent Negotiation for Optimum Voltage (INOV) technology, which allows you to adjust the voltage in 200 mV steps in the range from 3.6 to 20 V.

A point change in voltage depending on the current charge of the battery made it possible not to overheat the case, while charging time was further reduced. So, Qualcomm promises to charge the smartphone by 80% in 35 minutes. And it completely changes the habits when using a smartphone. Let's talk about this in more detail.

Use cases

Now most smartphones live one working day without charging with average use. As soon as you switch to a more intensive mode (games, for example, or active web surfing in LTE), this time is beautifully reduced to half a day. And then there are three possible options.

In the first case, you turn on the power saving mode and try not to touch your smartphone until the evening, which, you see, is not very convenient.

The second option is to use an external battery. In this case, you must either leave the smartphone alone for an hour or two, or put up with the fact that a long wire will stick out of it, leading to an external battery. A side disadvantage of this solution is the need to carry such a “power bank” with you, which also weighs like the smartphone itself.

Fast charging is a great alternative to the above two scenarios. Finding a free charge for half an hour is not difficult, especially if you are sitting in a cafe. We connect the smartphone, drink a cup of coffee and get an almost fully charged battery, and then use the phone in everyday mode.

Purchase

But why buy this? Charger, if it, in theory, should come with a smartphone? Unfortunately, even large manufacturers often save on this little thing and put a regular power supply in the box, although the Quick Charge 3.0 inscription flaunts on the package. But even if the smartphone is equipped with an appropriate charger, it usually lies at home, and you will need another one on the road.

And here the question arises: which power supply to choose? On the one hand, there are expensive solutions from large manufacturers for two thousand or more, and, on the contrary, there are cheap offers from various little-known companies. I don’t want to overpay for a brand, but it’s also scary to entrust charging a smartphone to a noname company.

A good alternative to both solutions is to choose a well-known Chinese company that has been operating in Russia for a long time, but has affordable prices. For example, power supplies with Quick Charge 3.0 are manufactured by Ainy, known to many users for their protective glasses based on Asahi Glass.

All Ainy accessories are inspected and rejected at our warehouse in Shenzhen. Therefore, at a relatively low price (only 800 rubles), their chargers have the quality of large manufacturers.

Conclusion

If your smartphone supports Quick Charge 3.0 fast charging, but did not come with a corresponding power supply, or if you want to have another travel charger, then it makes sense to take a closer look at chargers from Ainy. To get the opportunity to charge your smartphone by 80% in half an hour for only 800 rubles is a great offer.

One of the most pressing problems that every owner faces mobile devices, such as smartphones and tablets, along with an increase in their battery life, is to reduce the time we have to spend recharging their batteries.

Many owners of devices based on Qualcomm processors have heard about the support for their proprietary Quick Charge technology, which is designed specifically for these purposes. latest version Quick Charge 2.0, which will be discussed later, allows you to charge the battery of these tablets and smartphones 75% faster than conventional devices.

For example, with the Rapid Charge 2.0 charger, you can charge your device's battery to 60 percent in just 30 minutes.

How does it work? First of all, in order to understand how it is possible to achieve an acceleration in the process of charging the batteries of our tablets and smartphones, you need to know that they are charged using the current supplied to them from an external power source.

It is current, not voltage, that is the main factor that ensures the charge of the battery. Therefore, the higher the current supplied to the battery by the power source, the faster it will charge.

Increasing the charging current requires the use of more powerful power sources, as well as increased requirements for other components involved in this process.

This means that we cannot increase the power of the power supply indefinitely: not only are there current limits that a smartphone or tablet battery can withstand without overheating, but there is also a limit that is determined by the amount of current that the same Micro USB connector can pass through.

If the first problem is solved due to the fact that all our smartphones and tablets have a built-in current regulator, which is designed to limit it to a level that is safe for the battery, then the second can be solved by replacing conventional Micro USB 2.0 ports with more powerful ones, the Micro USB 3.0 standard.

Now back to Qualcomm's Quick Charge technology. The first version of Quick Charge 1.0 allowed to increase the charge current to the maximum value for the Micro USB connector, which is 2 amps, which allowed using up to 10 watts of power (with a 5 volt power supply: 5x2=10).

Quick Charge 2.0 technology allows you to increase the power delivered by the charger to the battery up to a maximum of 36 watts. Those who are familiar with electrics will say that this is not possible with a standard 5-volt charger, since this requires 7.2 amps of current to flow through the Micro USB connector. How can you get around this limitation?

The fact is that in this case, Qualcomm technology involves the use of power supplies with an output voltage of not only the standard 5 volts, but also 9, and even 12:

Thus, in addition to supporting Quick Charge 2.0 technology with your tablet and smartphone, in order to speed up the charging time of their batteries, you will also need a special power source (AC adapter) that comes with it.

At the same time, all chargers that support Quick Charge 2.0 are universal. For example, you can use Motorola Turbo Charger to charge HTC devices and HTC Rapid Charger 2.0 to charge Motorola smartphones.

Even if you are often near the outlet, a smartphone that has sat down at the wrong time can create many uncomfortable moments. What to do if it's time to go out, but the battery has not had time to charge? Or when you forgot to put your gadgets on charge in the evening, and in the morning they greet us with alarming discharge signs? Of course, you can always use an external battery, but you also need to have time to charge it. And it usually takes so long to charge...

Manufacturers of batteries and gadgets are well aware of this problem - and successfully solve it with the help of "fast" charging technologies. Let's take a quick look at modern fast-charging technologies, especially since they continue to develop rapidly in 2017. At MWC 2017, Meizu introduced the fourth generation of its fast charging technology, Super mCharge.

Super mCharge

Super mCharge technology allows you to fully charge a smartphone with a 3000 mAh battery in just 20 minutes. How fast is it? Equipped with this technology, the Meizu prototype surpassed the iPhone 7 Plus in charging speed by 11 times and was 3.6 times faster. samsung galaxy S7 edge. Still, in 5 minutes you can charge the gadget by 30%!

To achieve this result, a high-voltage direct charge (HVDC) method is used. The Super mCharge power adapter delivers 11V at 5A. This means that the maximum transmitted power reaches an impressive 55 watts. An ordinary charging cable cannot transmit such power - so to use Super mCharge, you will need not only a smartphone and an adapter that supports this technology, but also a separate high-power cable.

A separate plus is that the heating temperature of the battery case with such a "turbo charge" according to Meizu's promises will not exceed 39 °, which will allow you to comfortably work with your smartphone, even while charging from the mains.

Quick charge

For several years now, Qualcomm has been releasing chips that are compatible with its proprietary Quick Charge technology. Its support is provided either by using a separate chip in the system, or by a compatible Snapdragon chip. For this reason, Quick Charge technology is supported not only Android smartphones with a Snapdragon chip, but also separate external batteries - in particular models from Xiaomi.

In 2018, the fourth generation of Quick Charge 4.0 appeared, compatible with the USB Power Delivery (USB-PD) protocol via USB port Type-C. But previous versions of Quick Charge do not lose their relevance - they can reduce battery charge time by up to 75%. Due to the popularity of Snapdragon chips, support for this technology can be found in many flagships from various brands. Quick Charge 3.0 technology is backwards compatible with the previous ones - so if your gadget supports Quick Charge 2.0, a charger with the third version will work for it.

Quick Charge adapters charge your device faster by allowing your device to accept more voltage and current. If you connect Quick Charge charging to an old device, nothing bad will happen, but the gadget will charge at the same pace. As with Super mCharge, fast charging requires not only the support of the technology on your gadget, but also the appropriate charger. You can use a regular cable - and you can quickly charge not only a smartphone, but also an external battery!

Super Charge, Turbo Charge, Pump Express, RapidCharge, FastCharge, VOOC Flash Charging

Each manufacturer strives to implement its own version of fast charging for their devices. Alas, in anticipation of the "nano" or "graphene" batteries technologies promised to us by scientists (which, in theory, can be charged instantly), all current solutions are made according to a single technical solution - an increase in throughput power and current strength.

As an example of an alternative solution, we can mention OPPO with its proprietary VOOC Flash Charging technology. Thanks to the eight-pin battery, each of the internal cells is charged in parallel, with a current of 4.5 amperes and a voltage of 5 volts.

Pump Express works similarly to Quick Charge, but only with MTK processors, and Huawei's Super Charge boasts high-speed charging records (but only in its flagship devices).

Instead of conclusions

When choosing fast charging technologies, ask which ones your gadget supports. And if you have an iPhone or your smartphone does not support any of them, it doesn’t matter, just choose the right external battery with fast charge support, add it with the right network adapter and you will definitely not be left without communication at the most inopportune moment. And if you already have an external battery, pick up a charger that supports a charge current of 2.1A, so your iPhone will charge faster.

With the release of each new generation of smartphones, processors are getting faster, screen resolutions are getting higher, applications are getting more voracious, and batteries ... Batteries are still the same. To somehow compensate for this shortcoming, manufacturers use fast charging technologies. But, in addition to the benefits, they can bring a lot of problems to the smartphone owner - from banal incompatibility and reduced battery life to burnt smartphones and power supplies.

Today, a wide range of charging protocols are available to us, developed and promoted by various companies and organizations. We'll try to stick to chronology as much as possible.

Regular USB

USB allows a current of no more than 500 mA at a voltage of 5 V. Only much later, with the release of the USB 3.0 specification, the maximum current was raised to 900 mA. Ordinary push-button phones, which began to come out not with their own charging connectors, but with mini-plugs, and then microUSB, had quite a bit of power.

Everything changed with the release of smartphones, the battery capacity of which was several times higher than the relatively small battery capacity. push-button phones. Even small by modern standards batteries with a capacity of 1500 mA ∙ h already wanted to be charged faster than in 4–4.5 hours (time, taking into account losses during charging and a natural slowdown in the charge rate after 80%). There was a need to somehow transfer a larger charge current through a standard cable, without accidentally burning the USB controller if the device is connected to a computer.

USB Battery Charging Revision 1.2 (BC1.2)

This standard was adopted back in 2011 and allowed early devices to be charged from USB connectors with a current of up to 1.5 A at a voltage of 5 V. The standard is adopted by USB-IF, so its use is free for manufacturers. By modern standards, it is very primitive: the type of charger is determined by the voltage on the D + and D- contacts.

(Quick Charge), so users are actively using this useful technology. QC allows you to quickly and efficiently charge your smartphone, literally in an hour the battery charge is again 100%. 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 bring new innovations to the mobile device market. At one time, Quick Charge 1.0 technology clearly demonstrated that smartphones can charge up to 40% faster than with conventional charging.

A year later, QC 2.0 was introduced, allowing you to charge the device already 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 becomes as fast 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 has support for a 9V/2A charger, but it is charging with a 1A charger, the process will take much longer.

As 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.

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

Note: products without a certificate do not guarantee declared efficiency.

How does Quick Charge technology work?

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

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

Therefore, up to 50% of the battery can be charged in a short amount of time, but it will still take more than an hour to fully charge the smartphone.

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

Qualcomm is focusing consumers' attention not on increased charging speed, but on increased efficiency. So, the main innovation in the technology is the INOV function, which is able to intelligently select the required voltage, more precisely optimizing the power and charging time of a particular device.

Differences QC 3.0 from previous versions

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

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

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

The problem is that Qualcomm technology is developed by the manufacturer. 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 the full benefits of Quick Charge while charging your device.

Conclusion

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

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