What is quick charging or fast charging technology?

You’ve probably heard of quick charging or fast charging or turbo charging. Many may have already bought a quick charger from the market. In today’s post I will discuss quick charging technology.

First of all, I want to say one thing. There is no difference between companies that make and sell quick chargers, fast chargers, or turbo chargers. This means that whether the quick charger is from Samsung or any other company, the same technology is used in all chargers. Suppose you are using a Samsung phone. If for some reason your charger is damaged, then you don’t have to buy Samsung’s e-charger. You can buy any charger that matches your phone and battery power. This will not be a problem for your phone or phone battery.

What is quick charging technology and its evolution

Looking back 5 or 6 years from today, it can be seen that the battery capacity used in mobile phones at that time was much less. Since the capacity of the battery was very low, it was not a headache to charge the battery. Besides, we didn’t use the phone so much then. So we were happy with the normal charging technology.

But as the days went by, so did the use of the phone. Many powerful devices are now used in mobile phones, and the use of mobile phones has increased many times over. Now many powerful batteries are used in the phone. But the problem is that the charging time is still the same as before.

To solve this problem, Qualcomm invented the “Quick Charge 1.0” technology. The charging IC in this technology receives more power and also helps to charge the battery faster. A 3,000 mAh battery could be charged up to 30% in 30 minutes with Quick Charge 1.0. Then came Qualcomm’s “Quick Charge 2.0” technology. This technology came with Qualcomm’s new processor. This technology made it possible to charge a 3,000 mAh battery from 50% to 60% in 30 minutes.

Now let’s talk about the latest Qualcomm “Quick Charge 3.0” technology. Look at a normal charger, that is, a charger that we have used a long time ago, the output power was 5 volts x 1 ampere, that is, 5 watts. Then when Quick Charge 1.0 technology came, the output power was 5 volts x 2 amperes i.e. 10-watt charger. But Quick Charge 2.0 technology did not have a specific output power. In Quick Charge 2.0 technology, the output power depends on the current battery level. In 2.0 technology the output power is 5 volts x 2 amperes = 10 watts or 9 volts x 2 amperes = 18 watts or 12 volts x 1.6 amperes = 16 watts. That means the maximum output is 18 watts and the minimum is 10 watts. And these output powers tend to vary based on the battery level. The battery of any smartphone is not charged in the same way from 0% to 100%. You may notice that your phone charges very quickly in the beginning, but after charging 50% or more, the charging speed decreases.

When your phone starts to charge for the first time, the battery charges very fast as it is completely empty. But when it starts to charge slowly, the battery starts to receive less power. After 90% the battery charge is further reduced. Quick Charging Technology “Quick Charge 2.0” charges the battery as needed. Suppose it provides 16 watts of charge from 0% to 50%, because then the battery receives more power. It then delivers 10 watts of power after 50%, as the battery slowly consumes less power. So depending on the power of this battery, “Quick Charge 2.0” has to increase or decrease its output power.

Now Qualcomm can charge its latest technology “Quick Charge 3.0” by increasing the voltage from 3.8 volts to 12 volts by 200 millivolts. “Quick Charge 2.0” had an increase of 5 to 9 then 12 volts. That is, the charging power would come down directly from 12 volts to 9 volts and from 9 volts directly to 5 volts. There was no provision for middle volts such as 6, 7 or 8 volts. But in Quick Charge 3.0, the output power will increase from 3.6 volts to 12 volts by 200 millivolts. It will not come down from 12 volts to 9 volts like 2.0. Rather the voltage will increase or decrease much more slowly depending on the need of the battery.

Quick Charging Technology “Quick Charge 3.0” charges the battery according to the demand so you see a nice sequence of battery charging, and the battery charges quickly. “Quick Charge 3.0” will be seen with Qualcomm’s new processors such as 430, 617, 618, 620, and 720. Moreover, Qualcomm also licenses this technology to different companies.

Now if we talk about quick chargers, know that there are many quick chargers available in the market today. Many 3rd party companies make quick chargers. And Qualcomm certifies that “yes these quick chargers are standard and they are compatible with” Quick Charge 3.0 “technology. So if you want to buy a quick charger for your phone, it is not necessary to buy a charger that matches the brand of the phone. You can take advantage of quick charging technology by using any quick charger. However, I would say before buying a quick charger, see if it is Qualcomm certified on the packet. If Qualcomm is certified, it doesn’t matter which company you buy the charger from.

Some misconceptions about quick charging technology

Some misconceptions about quick charging technology

There are some misconceptions about quick charging technology, so let’s try to dispel the misconceptions.

  • Many people think that using a quick charger will waste the battery. No This is a completely wrong idea. A quick charger will never force your phone. It will charge according to the level of the battery. Not that the battery will blast because the charge is fast.
  • Many people think that buying a quick charger will start quick charging on your phone. In fact, if you only have quick charging technology in your phone, you can do fast charging through quick charger. Otherwise you will not get any benefit of Quick Charger.
  • Many people think that my phone supports quick charging so using slow charging will cause battery problems. In fact, it is not right. You can use any normal charger. Or you can charge with your laptop. This will not be a problem with your battery.
