Charging Protocols Owned By Various Mobile Phone Brands: What Impact Does It Have On Charging Speed - IETCHARGER

Apple, Samsung, Motorola, Sony, OnePlus, Huawei, Nokia,Google.These well-known mobile phone brands in our daily life all have their own patents or unique features. Charging is no exception, because when we use mobile phones, we must pay more professional attention to this aspect. At the same time, the comfort of mobile phone charging has a vital impact on our user experience. So, let’s talk about this aspect next.

Charging protocol

1、Apple

protocol:USB Power Delivery (USB-PD)、Qi wireless charging protocol、MagSafe wireless charging protocol、Apple 2.4A fast charging protocol

Note:Apple gradually began to use the PD fast charging protocol starting from iPhone 8. The iPhone 8 to iPhone 15 series all support the USB PD fast charging protocol. Among them, high-end models such as iPhone 14 Pro Max support charging power up to 29W.

2，Samsung

protocol:Samsung Adaptive Fast Charging (AFC), USB-PD, PPS（Programmable Power Supply）

Note:Samsung Adaptive Fast Charging (AFC) is their own customized charging protocol based on Qualcomm Quick Charge. The Galaxy S series and Note series should also have USB-PD and PPS protocols, so that the phone can support higher charging speeds.

3、Huawei

protocol:SuperCharge (SCP), USB-PD

Note:SuperCharge is Huawei’s proprietary fast charging protocol. Especially 40W, 66W and even 100W super fast charging. A small number of Huawei phones are also compatible with the USB-PD protocol.

4. Xiaomi

protocol:Mi Fast Charge, USB-PD, Qualcomm Quick Charge (QC)

Note：Xiaomi’s fast charging protocol is based on Qualcomm Quick Charge and uses a customized Mi Fast Charge protocol in high-end models. Xiaomi devices generally support 33W, 67W and 120W fast charging and are compatible with USB-PD.

5、OPPO

protocol:VOOC, SuperVOOC, USB-PD

Note：OPPO’s VOOC (Voltage Open Loop Multi-step Constant-Current Charging) is known and remembered for its high efficiency and low temperature. SuperVOOC is a faster version, and OPPO’s new phone models support 65W and 125W charging.

6、OnePlus

protocol:Warp Charge, USB-PD

Note：Warp Charge is an evolution of Dash Charge that OnePlus has made changes and optimizations to, which allows the phone to have extremely fast charging speeds, such as Warp Charge 65T. Of course, USB-PD is also supported on some devices

7、vivo

protocol:FlashCharge, USB-PD

Note：Vivo’s FlashCharge fast charging technology has functions such as intelligent device identification, automatic current matching, and automatic charging power adjustment, which can more effectively ensure the stability and safety of users during the charging process

What impact does the charging protocol have on charging?

The charging protocol has a significant impact on the charging speed. Different protocols define the way power is transferred from the charger to the device, affecting the efficiency, speed and even safety of charging. The following are the key points that affect the charging speed.

Slow charging speed: If you don’t use a matching charger, the charging efficiency and speed may be affected due to mismatches in voltage, current and other parameters, and may also cause irreparable damage to the device that needs to be charged.choose a charger that supports the corresponding fast charging protocol of the mobile phone, otherwise it will charge slowly or fail to charge.
Incompatibility:The main advantage of the private fast charging protocol is its high charging efficiency and high power, which can achieve ultra-fast charging. Of course, its disadvantages are also obvious. Its compatibility is relatively poor, and only devices that match it can achieve the maximum charging speed and safety.The main advantage of public fast charging protocols such as USB PD and QC is their wide compatibility, and they can be used by almost all devices that support USB interfaces.
Dynamic adjustment：Dynamically adjusted fast charging is basically based on connecting multiple cells (charge pumps) in series and handing over the voltage conversion operation to the charging head, and then making detailed voltage changes through the charging head rather than the mobile phone. Currently, many manufacturers’ fast charging has begun to be based on PPS programmable power supply, so as to achieve high-power (greater than 100W) charging.

Choose the charging protocol that suits your device

1、Check which protocols the device supports

When buying a charger, users should first check which charging protocols the device supports, and then choose the required charger and charging data cable.

2、Choose a trustworthy manufacturer

When choosing a charger, choose a trustworthy company. Because some companies claim that their products support a certain charging protocol, but in fact they cannot achieve the charging effect that the protocol should have, and some may even cause damage to the charging of the device.

3、Choose a charger with appropriate powerr

Different chargers have different powers, and the device also has certain requirements for power. Too high or too low is not good. You should choose a charger that suits your device.

Future Outlook of Fast Charging Technology

Current research on fast charging technology focuses on improving charging efficiency and safety, reducing heat generation of devices, and extending battery life. For example, some studies are exploring how to improve charging efficiency while reducing battery wear by optimizing battery management systems. Other studies are exploring new battery materials and designs to improve battery charging speed and safety. In addition, some manufacturers are also developing new fast charging protocols to further increase charging power.
In the future, with the further development of fast charging technology, we can foresee several possible trends.
First, the popularity of fast charging technology will be further improved. With the development of technology, fast charging is no longer the patent of high-end devices, and more mid- and low-end devices will also be equipped with fast charging technology. Secondly, the charging power will be further improved. At present, some mobile phones already support fast charging of more than 100W, and in the future, this number may increase further. However, high-power fast charging also brings challenges, such as heat management and battery life issues. Future fast charging technology research will need to solve these problems. Finally, fast charging technology may gradually shift to wireless fast charging. Although the power and efficiency of wireless fast charging are not as good as wired fast charging at present, with the development of technology, the performance of wireless fast charging will be improved and may become mainstream in the future.
