Qualcomm Quick Charge 3.0 Technology

As the need of performance and speed grows along with the evolution of smartphone, so does the need of energy, and that can be fulfilled by two means: By increasing the capacity of the battery or by increasing the rate of charging. Increasing the capacity of the battery results in the increase of the weight and dimension of the phones which can add up quite a cost to the phone. Also the heavier and bulky look due to battery capacity increment can also disgust the user into not buying the phone. This is the reason Qualcomm Quick Charge 3.0 was developed for all the phones running on the later series of Qualcomm Snapdragon processors.

Charging the battery is just like filling a bucket of water with water being the charges. The traditional method used in charging the battery is by filling the battery sending trickles of charge in order to overcome the risk of spilling of the charges due to overcharging. This is a very tedious process as it can take a hectic time to charge the current phones having high capacity batteries. What Quick Charge 3.0 does to improve charging rate is that it starts off slow and gradually increases the rate of flow of charge. When the battery is about to get full, it turns into trickle mode so as to prevent spilling of the charges. Thus we can see that the Quick Charge 3.0 technology can play a big role in the success of the present smartphones.

The only way to charge your battery faster is by, well, letting more charges in, in a shorter amount of time but simply increasing the output current or the input voltage won’t solve the problem. Charger with higher output current will obviously charge the devices faster but in order for the charger to function at maximum efficiency, the device they are charging also must support similar voltage and current.

Intelligent Negotiation for Optimum Voltage (INOV) developed by Qualcomm allows the Quick Charge 3.0 to coordinate with the device and adjust the voltage from 3.2V to 20V at 200mV increment resulting in 82 different voltage settings (Quick Charge 2.0 only had 4) which according to Qualcomm results in “Minimized Losses, Increased Efficiency, And Improved Thermal Performance.”

Quick Charge 3.0 is supported by devices running on the Qualcomm Snapdragon 820, 620, 618, 617 and 430 which means that the latest phones with a Snapdragon processors are already trying to show off their new charging efficiency against older phones running on Quick Charge 2.0.

Though the LeEco Le Max Pro became the first device to feature Quick Charge 3.0, some of flagships like LG G5, Xiaomi Mi 5 also sport Quick Charge 3.0 but Samsung Galaxy S7 and Sony Xperia X misses the part and supports Quick Charge 2.0.

    1. nothing remains forever, QC4.0, QC5.0 and so on will keep coming! how could QC3.0 remain standard?

      1. ultra mega hyper super charge 7.0 is on the way!

        for now, I’m feeding my mi5 with QC 3.0

  1. This is definitely something the smartphone market can’t do without.
    As phones are more and more used as the default Personal Computer, the battery drain is bound to increase for individual users.

    To keep the phones as lightweight as possible the option for increasing the battery size isn’t a welcoming option.
    Therefore the Quick charge 3.0 is very welcome for most users.
    Thumbs up for this technology

  2. Quick Charge 3.0 technology can play a big role in the success of upcoming smartphones..also going for a bigger battery size is surely not the right option.

    Quick Charge 3.0 will not only help smartphones to enhance their looks thereby attracting more users but will also help save time
