"Quick Charge 4+" which further strengthened Quick Charge 4 which can be used for 5 hours with 5 minutes charging, explanation on what it is all about

Qualcomm announced the quick charge standard "Quick Charge 4", which means "you will be able to use the terminal for 5 hours with 5 minutes of charging" in November 2016, but by further refining the battery charging speed It also improved by 15%Quick Charge 4+It was officially clarified that the appearance of "

For fast charging, look for Qualcomm Quick Charge 4+ in your next mobile device | Qualcomm

After investigation following Qualcomm's survey, Qualcomm has found that the functions that most users demand for smartphones, tablets, etc. are "extended battery life" and "fast charging", so Qualcomm is a mobile platform " Snapdragon "and fast charge standard"Quick Charge"We have been working on technology development to meet the two needs of" extending battery life "and" speeding up charging "of mobile terminals.

As a premise, Snapdragon is a processor designed with power emphasis on emphasis so that the terminal can be used all day on a single charge, and each generation Snapdragon uses the terminal many times a day We are considering power users considerably. Especially the latest Snapdragon 835 has succeeded in reducing power consumption by 25% compared with Snapdragon 821. The battery life is much longer, and if you are using a Snapdragon 835 terminal you can enjoy VR or stream play 4K movies Even so, you can use the terminal sufficiently with charging once a day.


And, with Quick charge standard "Quick Charge 4" adopted by Qualcomm, it was possible to charge the battery of smartphone from zero to 50% in only 15 minutes, but furthermore, this time, "improvement of battery life" "safety "Quick Charge 4+" was added, which added elements such as "improvement of sex" and "expansion of information on charging".

The main features of Quick Charge 4+ are three, the first of which is "dual charge" of parallel charge technology. Although it was also provided in Quick Charge 4 which becomes the previous version, it becomes more powerful in Quick Charge 4+, and the second IC for power management is installed in the device. Moreover, it is announced that by charging the device using dual charge technology, the current at the time of charging is divided, which leads to the reduction of heat dissipation and the charging time can be further shortened.

The second feature of Quick Charge 4+ is "intelligent thermal balance" which is a technology related to temperature management. Dual charge can be operated more efficiently by passing electric current while avoiding the part with the heat of the terminal when supplying electricity.

And the third is "advanced safety function" for improving safety. Quick Charge 4 also included a protocol for safety, but Quick Charge 4+ is designed to manage the temperature of the case and connector part further by going one step further, preventing excessive heating of the terminal, It is also possible to prevent damage to connectors.

As a result, the charging speed becomes faster by 15% compared with Quick Charge 4, the terminal temperature drops by 3 degrees, and it seems that the power efficiency will improve by 30%. Also, Quick Charge 4+ also has backward compatibility with past standards such as Quick Charge 3.0 and Quick Charge 2.0, and even with chargers compatible with Quick Charge 4+, it is possible to use Quick Charge 3.0 and Quick Charge 2.0 compatible terminals Charging is possible.


More quickly, the world's first smartphone "ZTE Nubia Z17" compatible with Quick Charge 4+ has appeared, and it is expected that compatible devices will be released one after another.
