If you are a xiaomi mi user, you may have heard the term QuickCharge, or HyperCharge công nghệ that comes with some new xiaomi devices. Alright, What are the differences in fast charging technologies?

Qualcomm QuickCharge

QuickCharge is Qualcomm’s fast charging protocol, most Qualcomm SoC devices supports this. QuickCharge công nghệ overcomes the standard 5V-1A limit, allowing the device lớn charge at higher voltages & higher currents. It was developed in 2013 và the first QuickCharge protocol (1.0) was released for users. Now, QuickCharge 5.0 is available today. Let’s take a look at other QuickCharge protocols.

QuickCharge 1.0 (QC 1.0 – 10W)

Qualcomm’s first fast charging technology. Introduced in 2013, it’s available in Snapdragon 215 and Snapdragon 600 series SoCs. Charging voltage max. 6.3V and current is max. 2A. Compared khổng lồ charging speed of older devices, QC 1.0 charges about 40% faster. For this protocol, it’s enough to integrate a PMIC with QC 1.0 support. A standard USB cable can give this speed, so there is no need lớn buy a new cable. Và Xiaomi’s first QC 1.0 supported device is Mi 2 (aries).

QuickCharge 5 (+100W)

Qualcomm’s latest fast charging protocol. It can go over +100W. It can charge a 4500mAh battery to 50% in 5 minutes. It came with Snapdragon 888 and 888+ processors.

World’s first QC 5 supported device is Xiaomi’s mi 10 Ultra (cas).

Qualcomm’s QuickCharge giải pháp công nghệ has formed the basis of other charging technologies. Let’s take a look at other charging protocols.

USB power Delivery (PD)

As you know, standard USB protocols have low charging speeds. Even USB 3.1 can reach max. 7.5W power. So fast charging requires a new technology. Here is where USB PD comes into play. Alright, what is USB PD?

USB PD (power delivery) technology, which is the most up-to-date protocol of the USB interface, can reach higher voltages with max. 5A. It has profiles for 10W for handheld devices, 18W for tablets and most peripherals, 36W for notebooks, 60W for larger laptops and docking stations, & 100W for workstations. Completely according to use.

USB PD 2.0 (100W)

This fast charging standart released 2014. PD interfaces only works with USB-C (USB-C lớn USB-C). Charging voltages and currents is 5V-3A9V-3A12V-3A15V-3A20V-5A, in addition khổng lồ its maximum charging power nguồn that reaches 100W. Apple MacBook 2015 is a good example for this.

USB PD 3.0 (100W)

The charging currents & voltages are exactly same as USB PD 2.0, but there is much improved. Added a more detailed description of the device’s built-in battery features. In addition, device software & hardware version identification & PD communication & software update functions included. Finally, and as a third improvement, the trick has been added lớn a certificate và digital signature functionality. In short, there is a device-specific PD charging protocol. This offers more efficient charging.

USB PD 3.0 PPS (+100W)

USB PD 3.0 PPS was introduced at 2017. PPS feature combines the two available charging modes of high voltage và low current and low voltage và high current, making them more sensitive & functional.

Also USB PD 3.0 PPS has USB Type-C interface, maximum charging power reaching 100W. Charging voltages & currents same as PD 3.0 is 5V-3A9V-3A12V-3A15V-3A20V-5A. But, with USB-IF Association‘s updates it now has specific PPS voltages of 3.3V-5.9V 3A, 3.3-11V 3A, 3.3-16V 3A, 3.3-21V 3A, 3.3-21V 5A.

USB PD 3.1 (240W)

USB 3.1 PD, the latest protocol published by the USB-IF Association. It’s an enhanced version of USB 3.0 PPS. USB PD 3.1, the latest version và with major improvements, divides nguồn into two ranges: standard nguồn range (SPR) and extended nguồn range (EPR). SPR is currently mainstream.

Its interface, of course, Type-C & includes all other PD protocol’s voltage-ampere ranges. Moreover this protocol has a 15V-28V 5A, 15V-36V 5A, và 15V-48V 5A current-voltage ranges.

In the phone market, they are actually the same, because PD supported phones generally use 18W or 27W. All táo bị cắn dở devices after iPhone 8 use USB PD interface, or Google pixel devices uses USB PD. So PD 3.0 standard is enough. Apple‘s phones use the USB PD 3.0 interface and consumes max. 20W (iPhone 13) power. Most flagship Xiaomi devices after 2019 tư vấn PD but don’t need it, because they uses QuickCharge technology.

Xiaomi HyperCharge (200W)

The huge technology that Xiaomi introduced last year. Xiaomi’s first 200W wired & 120W wireless charging powers were achieved. This technology, which first came with the Mi 11T Pro (vili), later came to lớn the Mi 11i Hypercharge (pisarropro) device as a name, well Redmi lưu ý 11 Pro+ 5G (pisarropro). Hypercharge can charge fully a 4000mAh battery in 8 minutes with 200W wired & 15 minutes with 120W wireless. Xiaomi mi breaks new ground in fast charging.
