As you may be aware, quick charging technology has become increasingly vital in our daily lives. It's really handy in everyday life since instead of charging your gadget in 2 hours, you can now charge it in 30 minutes. Fast charging is currently supported by the majority of today's smartphones.
If you're a Xiaomi customer, you've probably heard about QuickCharge or HyperCharge technology, which is available on select new Xiaomi smartphones. So, what are the distinctions between fast charging technologies?
Qualcomm QuickCharge
QuickCharge is Qualcomm's quick charging standard, which is supported by the majority of Qualcomm SoC products. QuickCharge technology goes above the conventional 5V-1A restriction, allowing the device to charge at greater voltages and currents. It was created in 2013, and the initial QuickCharge protocol (1.0) was made available to consumers. QuickCharge 5.0 is now available. Let's look at some more QuickCharge protocols.
QuickCharge 1.0 (QC 1.0 – 10W)
Qualcomm developed the first quick charging technology. It was first released in 2013 and is available in Snapdragon 215 and Snapdragon 600 series SoCs. Charging voltage is limited to 6.3V and current is limited to 2A. When compared to prior smartphones, QC 1.0 charges around 40% quicker. It is sufficient to incorporate a PMIC with QC 1.0 support for this protocol. There is no need to purchase a separate cable because an ordinary USB cord can provide this speed. The Mi 2 is Xiaomi's first device to support QC 1.0. (aries).
QuickCharge 2.0 (QC 2.0 – 18W)
QC 2.0 is the next generation of quick charging technology. In 2014, it was introduced. Available on the majority of Snapdragon SoCs launched between 2014 and 2016. Many Android smartphones are supported. There are voltage and ampere ranges of 5V – 3A, 9V – 2A, and 12V – 1.67A available, and it can charge at a maximum power of 18W. Xiaomi's Mi Note Pro (leo), for example, supports QC 2.0.
QuickCharge 3.0 (36W)
The following protocol is QC 3.0. In 2016, it was introduced. This will be the case for some time, and a new protocol will not be implemented until 2020. In other words, from 2016 through 2020, most Snapdragon SoC devices support QC 3.0. It has a voltage range of 3.6-22V and a current range of 2.6A – 4.6A. With 12V – 3A voltage and current, it can produce up to 36W.
It is distinguished from other protocols by its support for next-generation technology. INOV (Intelligent Negotiation for Ideal Voltage), for example, can determine the optimal voltage between 0.2V – 3.6V and 22V based on the scenario. As a result, the battery's health improves significantly. It can charge 75 percent faster than QC 2.0 while consuming 8°C – 10°C less heat.
QuickCharge 3+ (same as 3.0)
In reality, most of its features are identical to those of QC 3.0. The only feature is scalable voltage in 20mV increments, which is borrowed from Quick Charge 4. Snapdragon 765 and 765G chipsets will be available in 2020. Xiaomi's Mi 10 Lite 5G is the world's first device to enable QC3+ (monet).
QuickCharge 4 & 4+ (100W)
The battery-friendliness of Quick Charge 4 technology stands out. Qualcomm announced this protocol in 2016 with the Snapdragon 835 with the tagline "5 minutes charging – 5 hours battery life." It has a charging time of 15 minutes from 0 to 50%. It also supports the USB PD (power delivery) protocol. The Dual Charge function, which was included in QC 2.0, is still accessible. Included are INOV 3 and battery conserving technologies. It supports USB-C charging at 3.6-20V and 2.6 – 4.6A, as well as PD 3.0 charging at 5V – 9V and 3A. Charging power is limited to 100W with USB-C and 27W with PD 3.0.
QuickCharge 4+ is the same as QuickCharge 4, which was introduced in 2017 and just adds "Intelligent Thermal Balancing" and "Advanced Safety Features" technology.
QuickCharge 5 (+100W)
The most recent fast charging standard from Qualcomm. It has a maximum power rating of +100W. In 5 minutes, it can charge a 4500mAh battery to 50% capacity. It was equipped with Qualcomm Snapdragon 888 and 888+ processors.
Qualcomm’s QuickCharge technology has formed the basis of other charging technologies. Let’s take a look at other charging protocols.
USB Power Delivery (PD)
Standard USB protocols, as you may be aware, have slow charging rates. Even USB 3.1 can deliver up to 7.5W of electricity. As a result, quick charging necessitates the development of new technology. This is where USB PD comes in. So, what exactly is USB PD?
USB PD (power delivery) technology, the most recent USB interface protocol, can reach higher voltages with a maximum current of 5A. Profiles are available for 10W portable devices, 18W tablets and most peripherals, 36W notebooks, 60W bigger laptops and docking stations, and 100W workstations. Completely in accordance with use.
USB PD 2.0 (100W)
This rapid charging standard was introduced in 2014. PD interfaces are only compatible with USB-C. (USB-C to USB-C). The charging voltages and currents include 5V-3A, 9V-3A, 12V-3A, 15V-3A, and 20V-5A, with a maximum charging power of 100W. The Apple MacBook 2015 is an excellent illustration of this.
USB PD 3.0 (100W)
The charging currents and voltages are the same as in USB PD 2.0, however there is a significant improvement. A more extensive description of the device's built-in battery features has been included. Furthermore, device software and hardware version identification, as well as PD communication and software update functionalities, are integrated. Finally, as a third enhancement, the trick has been added to the functioning of a certificate and digital signature. In a nutshell, there is a PD charging methodology that is device-specific. This results in more efficient charging.
USB PD 3.0 PPS (+100W)
In 2017, USB PD 3.0 PPS was launched. PPS combines the two charging modes offered, high voltage and low current and low voltage and high current, making them more sensitive and functional.
The USB PD 3.0 PPS also features a USB Type-C interface, with a maximum charging capacity of 100W. The charging voltages and currents are the same as in PD 3.0: 5V-3A, 9V-3A, 12V-3A, 15V-3A, and 20V-5A. However, with the latest USB-IF Association upgrades, it now offers specified PPS voltages of 3.3V-5.9V 3A, 3.3-11V 3A, 3.3-16V 3A, 3.3-21V 3A, and 3.3-21V 5A.
USB PD 3.1 (240W)
The USB-IF Association's newest protocol is USB 3.1 PD. It's an improved version of the USB 3.0 PPS. The current version, USB PD 3.1, distributes power into two ranges: standard power range (SPR) and extended power range (EPR) (EPR). SPR is now widely used.
It has a Type-C interface and supports all other PD protocol voltage-ampere ranges. Furthermore, this protocol provides current-voltage ranges of 15V-28V 5A, 15V-36V 5A, and 15V-48V 5A.
They are actually the same in the phone industry because PD-enabled phones often require 18W or 27W. All Apple products after the iPhone 8 use the USB PD interface, as do Google Pixel devices. As a result, the PD 3.0 standard is enough. Apple's phones employ the USB PD 3.0 interface and have a maximum power consumption of 20W (iPhone 13). Most Xiaomi flagship products released after 2019 enable PD but do not require it because they employ QuickCharge technology.
Xiaomi HyperCharge (200W)
Xiaomi released a massive technology last year. Xiaomi reached its first wired and wireless charging capabilities of 200W and 120W, respectively. This technology, which debuted with the Mi 11T Pro (vili), was later renamed the Mi 11i Hypercharge (pisarropro) device, as well as the Redmi Note 11 Pro+ 5G. (pisarropro). Hypercharge can fully charging a 4000mAh battery in 8 minutes with a 200W wired charger and 15 minutes with a 120W wireless charger. Xiaomi makes new ground in the field of quick charging.
