You must have acquired a phone that supports fast charging technology, or heard about this term from one of your friends, so what is this new technology?
The battery is one of the most important features of smartphones It controls the number of working hours, and if the battery is small or slow in charging, this will bother you a lot, and in my personal view the battery is the backbone of the phone, so no matter how important the processor, random access memory and operating system are in the performance of the phone, they will not be so important For the same importance as the battery that originally controls the number of hours the phone works, because a weak battery will be a much greater obstacle when using the phone, if your phone comes with a weak battery, you will not be able to work on it for a long time, and therefore you will not enjoy its features, and it may run out of energy in Important times, and the difficulty is increasing here in the event that your phone does not support the fast charging feature, and this is what the smart phone makers discovered several years ago, so fast charging technologies began to spread recently in many phones in their different price categories, and given this importance and the rapid spread of this technology, Today we're going to talk about how fast charging works and what other technologies areThat interferes with its production and competes with Qualcomm Quick Charg technologies in a short and simple way, so stay tuned.
What is express charging and how does it work?
In short, fast charging is based mainly on the idea of increasing the amount of energy that is charged to the battery. The standard rate for any battery charging that takes place through the USB is through charging 0.5 amperes (A) of current using 5 volts (V) to produce 2.5 watts in the end. (W).
In the case of using fast charging technology, these numbers change somewhat, for example in the case of
Samsung 's fast charging through Adaptive Fast Charging technology, it charges 1.7 amperes (A) of current using 9 volts (V) to produce 15 watts ( W), and in the case of
Huawei's fast charging technology called SuperCharge, it charges 5 amps (A) of current with 5 volts (V) to produce 25 watts (W).
Fast charging technologies and standards available in the market
Qualcomm Quick Charge
It is considered one of the most famous and most popular fast charging technologies in the market, due to the spread and intervention of Qualcomm in the manufacture of various internal parts of smartphones, the most important of which is Snapdragon processors that interfere significantly with this technology as it comes with it optionally, so support for fast charging technology is not always required. In all phones with processors from Qualcomm, in addition to that, Qualcomm was one of the first companies to introduce this technology early before even USB Power Delivery technology.
Below is a table showing the versions and capabilities of express charging offered by this company:
USB Power Delivery
USB Power Delivery (USB-PD) is the official and basic technology announced by USB-IF in 2012, as it can be used with any electronic device that carries a USB port, provided that the manufacturer supports it with the appropriate electronic circuits.
This technology is characterized by its many options, which allows producing power up to 100 watts so far, and it also features support for bi-directional power technology, which means bi-directional power, which allows your phone to charge other electronic devices.

Various other charging technologies
In fact, these technologies are considered very few by the smart phone manufacturers, as we find that most of them are mostly not exclusively owned by them. Rather, it is a development or re-assembly of Power Delivery and Quick Charge technologies in a different way with another brand, for example. Tguenita Adaptive Charging from Samsung, and Turbo Charging technologies of Free
Motorola .
As for the exclusive technologies for smartphone manufacturers, we can find them in VOOC for
Oppo , and for Huawei's SuperCharge, both of which work with completely different and exclusive technologies.
