In order to pursue a better cell phone life experience, in addition to increasing the battery capacity, the charging speed is also an aspect of the experience, which also allows the charging power of cell phones to increase, and now the commercial charging power of cell phones has reached 120W, the shortest 15 minutes will be able to fill the phone.
Undeniably, high power chargers do bring faster cell phone charging speed, but due to the different fast charging protocols used by different manufacturers, each fast charging protocol is also confusing, if you want to experience fast charging, you must use the original charger, charging cable, not only charging becomes a hassle, but also make the extra chargers at home become wasteful.
Fast charging protocols on the market today mainly include Huawei SCP/FCP fast charging protocol, Qualcomm QC protocol (on behalf of cell phones Xiaomi), PD protocol (on behalf of cell phones iPhone), OPPO's VOOC flash charging, VIVO's Flash Charge flash charging.
The full name of Huawei's SCP fast charging protocol is Super Charge Protocol, while the full name of FCP fast charging protocol is Fast Charge Protocol. early Huawei uses FCP fast charging protocol, with high voltage and low current characteristics, such as the early 9V2A 18W, which was used in the Huawei Mate8 cell phone. Subsequent upgrades to the SCP protocol to achieve fast charging in the form of high current, such as the 66W fast charging used by the recently released Huawei Mate40 Pro.
The full name of Qualcomm QC protocol is Quick Charge, currently on the market with Snapdragon processor phones, basically support the fast charging protocol, the initial QC1 protocol supports 10W fast charging, QC3 of 18W, QC4 through the USB-PD certification, the development of today's QC5 stage, the charging power can already reach 100W +. It is worth mentioning that the QC fast charging protocol has now supported the fast charging standard of USB-PD, and this also means that the charger using the USB-PD fast charging protocol can directly charge iOS and Android dual-platform devices directly.
OPPO can be said to be the earliest cell phone manufacturer to start cell phone fast charging, the early "charging 5 minutes, talk 2 hours" slogan, still familiar today. In 2020, OPPO proposed a 125W super flash charging technology. I have to say, OPPO's fast charging is still something, not like other manufacturers using Qualcomm QC protocol, but using its own VOOC flash charging protocol, using a low-voltage, high-current charging scheme.
So in the market, you also see some machines that support 125W fast charging, of which realme actually has a close relationship with OPPO itself, so it makes sense to support 125W fast charging.
VIVO's Flash Charge is also a dual-charge pump, dual-cell design, the current maximum charging power has been developed to 20V6A 120W, in 5 minutes to charge the 4000 mAh lithium battery 50%, 13 minutes will be completely full. And now its iQOO models have long been the first commercial use of 120W chargers. In this aspect of cell phone charging, OPPO and VIVO's technology is still relatively advanced.
As for the USB-PD fast charging protocol, the full name is USB Power Delivery, a fast charging specification developed by the USB-IF organization, is currently one of the mainstream fast charging protocols. And Apple is one of the initiators of the USB PD fast charging standard, so now there are also Apple phones support fast charging, they use the very USB-PD fast charging protocol.
USB-PD fast charging protocol and other fast charging protocols are more like an include and be included relationship, currently USB-PD 3.0 protocol has included Qualcomm QC 3.0 and QC4.0, Huawei's SCP and FCP, MTK's PE3.0 and PE2.0, and OPPO's VOOC. so from an overall perspective, USB-PD fast charging protocol has more The advantage of "unification of the jungle".
It is because most of the fast chargers of different cell phone manufacturers are based on their own fast charging protocols, which are more mixed theory and do not bring the convenience of fast charging to users. So not long ago, Huawei, OPPO, VIVO, Xiaomi and other manufacturers led the launch of a "mobile terminal convergence fast charging technology specifications", aimed at solving the problem of fast charging compatibility, and once the problem is solved, then users will only need to use a fast charging charger, it can be different brands of terminal equipment, both to achieve the fast charging experience.
For consumers, the phone is compatible with the consistency of the convenience of charging is the charging experience we want, and once the fast charging protocols of different cell phone manufacturers to play, will undoubtedly reduce the number of chargers used, but also an environmentally friendly initiative, compared to the iPhone does not deliver the charger practice, the charger to achieve fast charging compatible is a powerful and viable measure of environmental protection.
