Qualcomm Quick Charge technology.

Qualcomm Quick Charge technology.

In the previous article, we have discussed the Dash Charge technology introduced by One Plus. But the main drawback of that technology was that this is exclusive to only those who have the One Plus devices otherwise there is no chance to enjoy this technology. Right…….? But hold on there exist another similar kind of technology which is not limited for any specific devices such as One Plus or more. So don’t waste any time further, let’s get started. In today’s post, I’ll discuss, Qualcomm Quick Charge technology.

But this technology is for Qualcomm integrated processors or SoCs. With this technology, you can charge your device at lightning fast speed. Qualcomm claims that their latest technology-enabled device can charge up to 85 % in just 30 minutes or even faster depending on various circumstances, which is way faster than Dash Charge technology.

About Quick Charge technology

Quick Charge is a proprietary technology which allows for charging the battery beyond the typical 5 volts and 2-ampere duo. To take the advantage of Qualcomm Quick Charge, both the charger and the device must support it. In 2012, the USB Implementers Forum (USB IF) announced that their USB Power Delivery (USB PD) standard had been finalized which allows for devices to transfer up to 100 watts of power over capable USB ports.

Beginning with version 3, the driving technology behind Quick Charge was named INOV (Intelligent Negotiation for Optimal Voltage), with ensuing versions successively improving upon allowed charging voltage levels.

Quick Charge version 4 was announced in December 2016 alongside the Snapdragon 835. Version 4 implements additional safety measures to protect against overcharging and overheating and it is compatible with both USB⁠ type C and USB PD.

Versions of Qualcomm Quick Charge

Quick Charge 1.0: This version uses 5 V voltage and 2 A of current combination i.e. powered by 10 W Power. It was released in the year 2013 and use in devices powered by Snapdragon 600 SoCs.

Quick Charge 2.0: This version uses the various value of voltages i.e. 5 V, 9 V, 12 V and a current of 3 A, 2 A, or 1.67 A with up to 18 W power. It was released in the year 2015 and use in the devices powered by Snapdragon 200, 208, 210, 212, 400, 410, 412, 415, 425, 610, 615, 616, 800, 801, 805, 808, 810 SoCs.

Quick Charge 3.0: This version uses the range of voltages i.e. 3.6 V to 20 V, dynamic with 200 mV increments 2.5 A or 4.6 A of current and powered up to 18 W power. It was released in the year 2016 and use in the devices powered by Snapdragon 427, 430, 435, 617, 620, 625, 626, 650, 652, 653, 820, 821 SoCs.

Quick Charge 4: This version delivers the power up to 18 W or 28 W. It was released in the year 2017 and powered the Snapdragon 630, 636, 660, 835, 845 SoCs.

Quick Charge 4+: This is the latest type of this technology and has various charging categories like 5 V, 9 V via USB-PD, 3 V to 5.9 V or 3 V to 11 V, 20mV increments via USB-PD 3.0 PPS (Programmable Power Supply) and 3.6 V to 20 V, 200 mV increments via QC charger and the current of 3 A via USB-PD, 2.5 A or 4.6 A via QC. It delivers the power up to 27 W via USB-PD. It was released in the year 2017 used in Snapdragon 845 SoC devices.

The basic difference with Dash Charging technology

In the previous post, I have discussed the basic principle of Dash Charging. So here I will discuss the basic principle of Qualcomm Quick Charging. Qualcomm Quick Charging technology doesn’t increase the charging current as Dash Charging does, but It increases the voltage to increase the power output.

Pros and Cons of this charging protocols

Pros:

  • It is the fastest charging protocols available widely among various charging technology so far.
  • It can charge your device up to 85% in about half an hour.
  • Compatible with many  Android devices.

Cons:

  • The devices heat up a lot during charging because of the high voltage.
