Quick Charging Technology (Quick Charge)

What do you need to know about Quick Charge 3.0?

Fast Charging Technology is a very helpful feature for heavy mobile users. Qualcomm recently announced a new "Quick Charge 3.0" technology, promising a number of improvements over circuit charging in previous generations. So let's solve what's new.

What is Quick Charge?

If you just heard about the concept of fast charging, the result is that your smartphone can be charged faster than without using Quick Charge technology.

At the simplest level, Quick Charge allows the current to flow to the battery to a high level, in an effort to maximize charging efficiency. The latest Quick Charge products also tend to charge their batteries at higher voltages, allowing for a higher level of power transfer over a commonly-discovered cable.

However, the phone and charger must be compatible with the charging voltage and current. Your phone can support charging at 9V / 2A, but if you only have 1A charger then the process will take longer. Likewise, plugging a 2A charger into a phone that can only accept 0.7A will not make it cost much faster.

It is also possible to charge compatible devices quickly using only the same high charger, but a non-certified product clearly does not guarantee its working efficiency.

If your battery runs low, Quick Charge can help to push your smartphone faster than the lower current charger.

Quick Charge, like similar technology from other companies, is designed to optimize power transfer at an early stage of charging, allowing users to unplug their devices with suitable battery capacity after a short time.

Qualcomm is proud to charge multiple devices up to 80 percent in just 35 minutes, but it's very rare for a company to talk about the total cost time, because it's just less impressive. power transfer in the last stage of the battery charging is much lower regardless of the charging technology used, then why Quick Charge can boost the battery to 50 percent or more rather quickly, but it will still take more than an hour to fully charge your smartphone.

Quick Charge 3.0

Qualcomm boasts a fourfold increase in charging conventional chargers with Quick Charge 3.0, up from the 40 percent speed increase offered by first generation technology. However, one of the interesting things to note is that Qualcomm did not tout its big increase in charging times over version 2.0, rather the company focused on improving efficiency this time around.

The Quick Charger 3.0 feature is INOV (Intelligent Negotiation for Optimum Voltage), which allows the output power to be adjusted and the charging cycle can be optimized. First, different batteries require different charging voltages. Version 2.0 supported four modes at different power levels, 5 volts / 2amps, 9V / 2A, 12V / 1.67A, and 20 volt options. This Quick Charge 3.0 INOV communicates with the device to request any voltage between 3.2V and 20V at a 200mV increase, allowing for a wider selection of voltages.

INOV has the added benefit of being able to dynamically adjust the charging voltage during the battery charging cycle. As the battery charges, it slowly decreases slightly, partly the reason why it takes longer to fill the last 20 percent of the first. Qualcomm stated that the new technology allows the phone to request only enough voltage to achieve the desired cost, thus maximizing efficiency.

This is useful because it reduces the amount of energy wasted while charging. Previously, the extra power not used to charge the battery will be lost as heat, warming your phone and reducing the longevity of the battery. By exerting more control over the charging efficiency, less power is wasted, resulting in less heat. Qualcomm states that versions 3.0 up to 38 percent more efficiency than 2.0, which is a considerable energy savings.

Energy efficiency is a major new feature in Quick Charge 3.0, but this is still very important because the cold battery will last longer than hot.

3.0 vs 2.0 vs 1.0

Perhaps the best way to look at this is to compare the charging values between each of Qualcomm's Quick Charge revisions.

Here we can see that the amount of current offered by Quick Charge remains relatively consistent, but increasing the charging voltage has helped refuel faster. With 3.0, the voltage range will allow for faster charging and better efficiency.

For smartphones, the maximum amount of power that is actually available has not really changed from the maximum Quick Charge 2.0 18W. The new 9V model will still take the same 18W peak power as before, although low voltage batteries can receive a power boost, allowing them to charge a little faster than before. But this all depends on the right hardware.

Most importantly, Qualcomm has maintained its previous compatibility with its 2.0 and 1.0 standards. You will receive the maximum amount of secure power for your device by using one of the certified chargers. However, you will not reach full charging speed if you try charging a new phone with a longer, lower charger.
