HOW FAST CHARGING WORKS
Hello dear readers of Tecnogalaxy, today we are going to explain how fast charging technology works.
So, 3 years ago, we pretty much all had the same charger that outputs 1mA at 5V. Life was pretty simple back then because smartphones didn’t have powerful SOCs or high-resolution, high-refresh rate displays.
So here it is, we people don’t want our smartphones to download at the wrong time, when we need them most. And Murphy’s law affects us all the time we needed the smartphone.
Murphy’s Law: “Anything that can go wrong will go wrong”
We spend at least a second a day thinking about charging our smartphones. We end up charging it for about 2-3 hours a day to meet our needs using it.
A normal 4000 mAh smartphone needs to be charged for about 2.5-3 hours for the smartphone to reach 0 to 100% battery.
Typical chargers charge the phone at a controlled and steady rate. If the current flows too fast, the battery could fry, and if things go really bad it could fry the phone. So, immediately, our phone’s charging speed is limited by what its internal regulators allow.
So we think charging our phones for 5 minutes before we leave will make all the difference. Hell yes, it makes a difference with fast charging technology.
How fast charging works
Fast charging is an increasingly popular feature that lets you turn on your device in a fraction of the time it takes to do it the old-fashioned way. But not all products use the same type of fast charging, and not all chargers support the various standards.
Fast charging technology functionality supported by some smartphones and tablets that can be charged up to a whole day in 30 minutes.
With phones equipped with octa-core CPUs, high refresh rate OLED displays, there’s only so much a smartphone battery can handle. So one way to improve battery life would be to fill the phone with a bigger battery. But that may not be the exact solution.
Then comes fast charging or fast charging technology.
This technology is one such method that the designers of smartphone companies have come up with to charge the mobile phone quickly by feeding it with more power (voltage x current).
The output of a charge is measured in amperage and voltage. Amperage (or current) is the amount of electricity flowing from the battery to the connected device, while the voltage is the intensity of the electric current. Multiplying the volts by the amperes gives the wattage, the measure of total power.
It’s a technology originally developed by Qualcomm that involves pumping into a phone’s battery with a high-powered tool that reaches around 60 percent and then flush charging the rest of the way.
Now, this technology is also licensed by other OEMs (Original Equipment Manufacturers) such as Samsung, Moto, One plus, Asus, Oppo to name a few, who then go on to name their own marketing names such as Moto’s Turbo Power or the Samsung’s fast charging adapter and One plus’s Dash charger.
When using a Quick Charge 4 device, all you do is open the door a little more to let in more energy. So the basic concept is to allow more power to your smartphone, the faster the device charges.
So Samsung and Oneplus use signaling tricks that would allow their chargers to communicate with their devices.
