Today we are in the quest of getting most out of our smartphones.OEM'S have achieved most of the things that a daily user wants; but battery life still remains a major area of concern.Many solutions are being tried to overcome this major con; from squeezing in bigger battery to making power efficient SOC'S, everything is being tried out.One such solution,was introduced by QUALCOMM,known as the QUICK CHARGE technology,which is now being used by most of the phones.In last lesson we learnt about 'CHARGING ADAPTERS', today we shall learn about Qualcomm Quick Charge.Hey fellow MIUIers, this is Soumya from the MIUI DEVICE TEAM, lets get started!
BACKGROUND-
With the increasing smartness of our phones, a bigger battery was needed to overcome the challenges of a daily user.Putting in bigger battery meant, more time being required to charge the device.At this point of time the traditional 1A charge or the 0.5A output from the USB port of computers, was not enough to charge the bigger battery that the smartphone had. It took 6-7 hours to charge the phone via them, or maybe even more than that, so to overcome this, Qualcomm came up with a solution, which was widely welcomed.
WHAT IS QUICK CHARGE? HOW DOES IT WORKS ?
Batteries are charged by the current delivered to them by the power source.Applying additional current at a set battery voltage results in more power, which can result in more power, which can result in faster charging but also requires sturdier charging components that can withstand such high power levels.
Quick Charge fouces on inputing larger voltage to your phone. There are chargers,which are Quick Charge certified,which provide more power then the traditional 2A chager, which is commonly used by most of the devices. Though providing more power was not the challenge. The challenge was to publish SoC'S which could withstand such a great power. So, that is why we see only Snapdragon chipsets support Quick Charge.So, Quick Charge can be defined as A technology introduced by Qualcomm, implemented on Snapdragon chipsets, which focuses on pushing in more power, to charge the device battery faster.It can be categorized into three types, namely-
Class A devices allow for a max charging current of 3A, depending on the power source.The typical smartphone charger will run at 5 volts, drawing 3A of power, boosts Quick Charge 2.0 upto 15 watts of power; which is greater than the conventional charger used before. Class A devices also work with 5, 9,or,12 volt supplies and can tolerate more power.SoCs supported were Snapdragon 200,400,410,615,800,801,805,808,and 810.
The new feature with Quick Charge 3.0 is Intelligent Negotiation for Optimum Voltage (INOV) which supplied power according to the demand of the phone, because different batteries require different charging voltages.Quick Charge 2.0 supported four modes of charging battery-5V/2A, 9V/2A, 12A/1.67, and a 20 volts option. With the intoduction of INOV, the device can ask for anything between 3.2V AND 20V at 200 mV increments. The SoCs which were supported this time were- Snapdragon 820, 620, 618 (or Snapdragon 650), 617, and 430.
With this Qualcomm seeks to give users bigger battery life, reducing the battery temperature while charging and loss of power.

COMPARISON BETWEEN CHARGING TIMES OF STOCK CHRAGER, QUICK CHARGE 2.0 AND QUICK CHARGE 3.0
DID YOU KNOW ?
If ever noticed, every OEM states that how fast it could charge the device to 60% or 80%. Why is it so?
There are three stages of battery charging- Speed, Continuous, Trickle. It is easier to push in the power, when the potential difference between the battery and the charger output is high, i.e., when the battery is low. As this difference starts to reduce, pushing in the power becomes difficult, and charging the battery above 80% takes a lot of time; sometimes even more than the time taken to charge the device upto 80%, it is uncertain. This is why, charging time upto 80% is stated.
