Select a mains charger. Choosing a network charger with degrees of protection for microcircuits
It has long been noted by experts that containers batteries not enough for long work devices. Moreover, many of them have Lately increased appetite for electricity consumption. Therefore, Qualcomm decided to upgrade the already familiar Quick Charge technology according to the first and second versions. A new version accelerated charging Quick Charge 3.0 batteries cope with their assigned responsibilities much more efficiently than their predecessors.
Unlike Quick Charge 1.0, this technology charges the battery 2 times faster. Quick Charge 2.0 doesn't have such a big gap, but it still fully charges a smartphone or tablet 38% slower than Quick Charge 3.0. It should be said that standard way recharging the device is 4 times inferior to a new one. An updated version of Quick Charge technology charges a mobile device by 80% in 35 minutes and at the same time reduces energy consumption and overheating of the device.
This technology increases charging speed by optimizing the process itself, reducing energy consumption and reducing heat generation that is harmful to batteries. However, this technology has certain limitations. For example, if you connect a 2 Amp smartphone to a 0.7 Amp charger, then fast charging mobile phone will not happen.
Let's compare specifications current Quick Charge technology with previous solutions to understand what its advantage is:
The main innovation here is INOV technology, which allows you to significantly speed up the charging process. This smart voltage matching feature helps devices independently set the desired voltage level. So, if in the 2nd version you had to choose between 5, 9, 12 and 20 V, now the mobile device will be able to change the voltage in the range of 3.2-20 V in steps of 200 mV. Besides, new standard supports USB Type-C.
Different batteries require different voltages when charging. INOV allows you to calculate the output power and thereby improve the charging process. The previous version of Quick Charge provided 4 operating modes: 5V/2A, 9V/2A, 12V/1.67A and 20V. The new method is designed to connect to a gadget and find out the required voltage reading from it. As a result, a wide range of voltage levels are supported.
INOV makes it possible to dynamically adjust to the voltage level required by the battery. As INOV charges, it gradually reduces the required current. This is why it takes longer to charge the last 20% of the capacity.
The latest development optimizes the voltage supply and reduces wasted energy. Considering that excess energy always turns into heat, this option not only increases energy saving, but also increases the battery life, since the gadget stops heating up excessively. That is, the main innovation here is not the speed of charging, but the ability to save energy.
Quick Charge 3.0 is based on charging the battery with a higher voltage. Of course, mobile and Charger must support operation with existing voltage and current parameters. For example, if a smartphone is designed for 9B/2A, and you only have a 1 Amp power supply, then for full charge devices will take longer.
It is worth noting that the new product has not lost backward compatibility with previous versions of the standard. And yet, when charging the latest generation of devices with chargers of lower power, it is impossible to achieve the highest speeds.
Even though all of Qualcomm's latest chipsets have Quick Charge support, phone and tablet manufacturers have had to use specialized circuitry to make the fast charging option work properly.
Today, Qualcomm is primarily a chipset maker, but 20 years ago it produced Cell Phones. It is possible that the accelerated charging feature will be supported by inexpensive devices produced jointly with Microsoft. Qualcomm also created technology for wireless charging of metal devices, and its Snapdragon processors used in many popular phones and tablets.
Today, innovative Quick Charge 3.0 technology is supported by everyone flagship smartphones(for example,), released based on Snapdragon 820/821 chips, as well as some new products in the mid-price range. According to experts, this development has become one of the most attractive options in smartphones of the past year.
Many Xiaomi smartphones are initially equipped with Quick Charge technology, which is actively used by users mobile devices. The function replenishes the battery energy in the shortest possible time, so after an hour its performance increases to 100%. To study, we suggest disassembling fast charging version 3.0 to find out everything you need to know!
Quick Charge
Qualcomm Technologies distributes mobile phones the most current innovations, so the first modification of the technology showed that the speed of charging gadgets can be much faster compared to the standard procedure. After one year of development, the manufacturer demonstrated the second version of the option, which speeds up the process by 75%, while highlighting various attributes that can be used additionally.
As of 2015, the function continues to improve and only shows an increase in the speed of energy replenishment. Therefore, at the end of 2017 of the year Xiaomi presents more than 10 models that are equipped with Quick Charge 3.0.
By activating the fast charging option, more current is supplied to the battery, greatly increasing efficiency. To perform the procedure correctly, the smartphone and charger must correspond to the same voltage. For example, when the device is equipped with the necessary technology with a resistance of 9V/2A, however, using a 1A adapter, the procedure will require much more time.
Another scenario is that if a charger rated at 2A is used with a phone for which the maximum value is 0.7A, the speed of the procedure will not be accelerated. However, the device can replenish energy faster, provided that an identical adapter and power supply are used, but with a higher voltage. The project website notes that an uncertified product may not correspond to the declared properties.
How does Quick Charge technology work?
The fast charging function adjusts the current supply to the battery of the mobile device at the initial stage of the procedure. Therefore, some smartphones replenish up to 80% of energy in half an hour. Moreover, upon completion of the process, the voltage is not so high, regardless of what modification of the technology is used. Accordingly, the first half of the battery capacity can be filled in a short time, but it will take more than one hour to finish.
What's new in Quick Charge 3.0?
The third modification of the technology increases the speed by 4 times, so compared to the previous version, the results have increased by almost 40%. Manufacturer Qualcomm focuses more on discussing practicality instead of improving performance.
Therefore, the main innovation is the INOV option, which provides an intelligent selection of properties that sets the correct power and energy replenishment time for a specific phone.
Differences between QC 3.0 and previous versions
To determine the main difference between the most current version of fast charging from its predecessors, it is necessary to study their features, after which it can be decided that by increasing the voltage, the process time has been reduced with each new modification. The highest power rating in Quick Charge 3.0 is almost the same as the second generation – 18 W. At the same time, for batteries with a smaller capacity, the rate of energy replenishment increases, due to which less time is required.
Xiaomi without Quick Charge support
Why does your smartphone not support fast charging? Such questions most often arise from users whose phones do not have the appropriate technology. For example, owners of the popular Xiaomi Mi A1 on pure Android were disappointed by the inability to use Quick Charge. The reason is that it belongs to Qualcomm, so its availability depends on the chipset used in the device. As a result, all the nuances must be taken into account by the developer in the process of designing a new gadget model.
Based on the manufacturer's statements, a certified charger can be used with devices without technology support. There are no problems with this, but you will not be able to take advantage of the corresponding features during charging.
Conclusion
The Quick Charge option has great potential and popularity, since developers are constantly introducing improvements, providing various innovations in version 4. Smartphone owners will be impressed Xiaomi models using QC 4.0, which is expected to be released in early 2018.
(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, more than high level current, 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 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 latest version quick charge technologies from 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. Maximum power in the third version it 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 technology 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 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.
The technological process does not stand still, and modern phone manufacturers are releasing more and more sophisticated models with many latest features. Active improvement of software and hardware functionality leads to the fact that time battery life devices is reduced. Big RAM, powerful processes, multi-inch touch screens and strong cameras - all this contributes to the fact that the batteries are discharged quite quickly. This is why it is important to have a reliable memory. Great if original charger preserved, but what to do if it is lost or broken? Then buying a new one raises the question of not only preserving the functionality of the phone, but also your own comfort.
Everyone has experienced their smartphone running out of power at the most inopportune moment. This is especially scary when there is sorely not enough time to recharge. At such moments, the first charger that comes to hand is grabbed, connected and the countdown begins. Sometimes the process happens quickly, and often it takes a treacherously long time. The result is sad - after some time there is no connection again. Today we’ll figure out how memory devices differ and how to make the right choice.
Charger type
Before purchasing, many people wonder which memory is better to choose: original, analog or universal? Many people buy the original, which means they do not worry about the compatibility of the device with gadgets, the speed and features of charging, as well as various risks (cheap chargers that are sold in tents in markets may well lead to strong heating of the battery). But it is not always possible to buy original device, Then the best option will become a high-quality analogue. It contains a list of compatible device models, as well as technical characteristics that are identical to those of the original.
Power connector
The memory can have different connectors:
The weakest link in the charger is the cable. If it is non-removable, then if it breaks, it is almost impossible to restore the functionality of the device. If it is removable, then the adapter itself, which is plugged into the network, can be used further by simply purchasing an additional wire.
When choosing a charger, it is better to give preference to proven brands. For questionable devices, the cable can reduce charging efficiency by up to 75%. And this is not only a loss of electricity, but also of your time. In addition, such cables can break or come off the connector, which ultimately remains in the device. This leads to a short circuit and failure of the device.
Fast charging
Some charger models have fast charging. She may be:
According to the developers of Quick Charge technology, battery charging can be accelerated by up to 75%. In the first few minutes, smartphones that are compatible with Quick Charge are charged for several hours of use. This is really convenient in the modern rhythm of life - you run into a cafe, plug in your gadget, drink a cup of coffee and leave with a phone with a decent battery charge.
The key difference between Quick Charge 3.0 technology and 2.0 is the presence of the INOV function or intelligent determination of the optimal voltage. Depending on the progress of the battery charge, the required current strength gradually decreases. This allows you to minimize wasted energy during recharging.
Using a special adapter with the Pump Express+ 2.0 function, you can fully charge your smartphone battery 1.5 times faster compared to a standard charger.
Price issue
Today, chargers are available in a wide price range. So, having spent:
from 65 to 300 rubles you can buy branded chargers for devices of various brands ( Sony Ericsson, Samsung, LG, Apple or Nokia). They can be without a wire, as well as with a removable or non-removable wire.
From 300 to 1000 rubles you can purchase universal chargers in a durable case with two USB connectors. They will become an indispensable companion when traveling and in everyday life.
for more than 1000 rubles you will receive reliable and practical chargers from leading brands. A number of models have the Quick Charge 2.0 or Quick Charge 3.0 fast charging function, in which the charging power is increased by voltage rather than current. Which is absolutely safe for the gadget, because... it does not overheat.
