Smartphones have come a long way in recent times. Several manufacturers are continually improving the way a smartphone looks. And, in the same process, they have introduced several new technologies such as the edge-to-edge display, dual camera setup, etc.
But, one space where smartphones have seen a downside is regarding charging technology. We can give two instances for the same. One is that Android smartphones over the course of years are plagued with several battery life issues and manufacturers failed to deliver the best battery smartphone till date. The second scenario is instead of developing a smartphone with a good battery life, they are now stepping into a bandwagon to develop a technology which decreases the charge time of a smartphone.

In the same arena, OnePlus has come up with their charging tech called as 'Dash Charge,' whereas on the other hand, we have the world's best camera phone- the Google Pixel XL with Qualcomm QuickCharge 3.0.
Here's how both these technologies work. Do check out which one is the winner.
You might not be aware of the fact that OnePlus' Dash Charge is based on Oppo's VOOC (Voltage Open Loop Multi-step Constant Current Charging) tech. And, you might not be aware of another fact that, OnePlus before stepping into the smartphone market, was one of the subsidiaries of Oppo and now they have taken the same technology and rebranded it as Dash Charge.
On the flip side, the QuickCharge 3.0 found on Google Pixel phones and several other phones is being developed by Qualcomm solely. And, this QuickCharge technology can only be seen on smartphones that use Qualcomm chipsets.
How they Work?
Before we proceed to the technical terms, you should know about the batteries used in smartphones these days. Most phones launched in the past four years or so came out with Lithium-ion batteries (which of course explodes at times). The sole reason for the manufacturers to use Lithium-ion batteries is that they charge quickly from the zero state.
There is a saturation point in this battery recharge cycle. When these Lithium-ion batteries reach 70 percent of charge, this saturation point will come into play, and it slows the charging level to prevent the batteries from exploding.
So, both the Dash Charge and QuickCharge 3.0 work on the same principle. But, there is a slight difference between them. The Dash Charge uses the higher current range (5V/4A), whereas the QuickCharge goes with the higher voltage (5V/2A). But, powering them directly will result in the explosion of the smartphones.
As said earlier, QuickCharge 3.0 works only with the phones embedded with Qualcomm's chipset. That being said, the company is using a special chip inside the phone to control the voltage flow. However, that isn't the same case with Dash Charge.
You might be aware of any of your friend who owns a OnePlus 3 saying that I need to get my charger with me. Why? Here's the answer. OnePlus has embedded the entire circuit into their wall charger. OnePlus has taken this step especially to keep the phone cool even while charging.
Also, you can notice that phones with QuickCharge do heat a bit on charging. We experienced the same with our review unit of Google Pixel XL. Also, do make a note that you can use Dash Charge phones even while charging.
Yes, it matters a lot for modern day people. When OnePlus announced the Dash Charge tech with their OnePlus 3, everyone was skeptical on their take that it charges the phone in just 90 minutes. But, after trying out that feature, everyone was like 'WOW.'
And, OnePlus officially has released a video comparing the charging time of OnePlus 3T and Google Pixel XL. Have a look at the video below.
Points to Note
1) The Dash Charge on OnePlus devices only works with the proprietary charger bundled with the phone.
2) There are several QuickCharge certified chargers available in the market right now. So, a QuickCharge supported phone can be charged with any of them.
As seen in the video above, the Dash Charge on OnePlus phones is way better than the QuickCharge 3.0 on Google Pixel XL. Also, at the Qualcomm summit concluded recently in New York, the company introduced their next generation QuickCharge 4, which we expect to be much stronger than the Dash Charge.
