Quick Charge: What It Is, Types And How To Know If My Smartphone Supports It (Part I)

There are a thousand myths and counter-myths about what is good and what is bad when it comes to taking care of your phone’s battery.

But there is one thing on which there is more or less consensus: it is not advisable to leave your mobile phone charging at night for many hours.

The problem? A full charge takes several hours, and during the day you may not have time to charge it completely.

Luckily, that’s what Quick Charge is for, a technology that with the advent of more and more capacity batteries has become little less than essential.

The idea is simple: to charge the battery of your phone much faster, so that your mobile is the shortest possible time connected to the power.

1. What is Quick Charge?

The name is enormously descriptive, but in case someone is clueless, the quick charge is the generic name given to several similar technologies whose goal is to charge a battery (for example, your mobile) at a higher speed than usual.

The exact method by which the charge is faster may vary according to the different systems, but in a simplified way it is something as simple as increasing the “power” so that the battery is charged faster by increasing the voltage, the amperage, or both.

If the battery were a bottle of water, instead of refilling it with small glasses of water, you would use a hose to refill it quickly.

“Oh, so it’s simple, all I have to do to charge my phone fast is plug in the most powerful charger I can find. Yes and no.

As a general rule, you should always use the original charger or at least recommended as the manufacturer and, in addition, electronic devices have a regulator to limit how much power they can receive from their charger. In the example of the bottle above, it would be the neck.

It’s no use plugging a pressure hose into your bottle if most of the water can’t get into it, and it’s also no use using a tablet charger if your phone refuses to let in more power than normal.

It’s not that the manufacturer is stubborn and opposes progress, it’s for the safety of the device, its battery and yours.

2. Hardware and software

In this article we are going to focus on Quick Charge technologies popularized by manufacturers such as Qualcomm, MediaTek or OnePlus, but the truth is that charging the phone all helps, and hardware and software go hand in hand.

The charging speed of any device is a simple mathematical operation between how much power the device is gaining via its charger minus the power it is consuming during use.

If at that moment the device is completely turned off (its consumption is zero), the charge is therefore as fast as possible.

In our case, these measurements are made in mAh, a unit that you will surely recognize because it is the one used to describe the capacity of the batteries.

Specifically, mAh means milliamperes per hour and is a figure that by itself does not tell you how long your phone will last on: it will depend on how much you use it.

Going back to math, with a 3000 mAh battery you could keep one device spending 100 mA for 30 hours or another spending 150 mA for 20 hours.

This is where the software comes in, because reducing the energy use of the device makes the charge faster, and is the premise on which a thousand and one Google Play applications are based that promise to “Boost” your charge.

To achieve this, there are many resources available to manufacturers to achieve the fastest load.

From limiting processor power to lowering brightness, closing applications or directly entering a super energy-saving mode that resembles more a feature phone than a smartphone.

Although a phone in power-saving mode – or turned off – charges faster than one that is in use, with the screen on and a game with 3D graphics, this is not considered a quick charge.

Quick Charge is charging at higher speed, on equal terms. Some manufacturers mix both concepts for greater efficiency.

3. Types of Quick Charge

There are several types of Quick Charge on Android, although the most popular system due to its extension is probably Qualcomm’s: Quick Charge. These are, to this day, the main types of Quick Charge.

Qualcomm Quick Charge

It is the most extended technology given the extension of the Snapdragon chipsets in which it is included. Since its first version, revisions 2.0, 3.0 and the recent 4.0, integrated in the new Snapdragon 835, have been released.

Explaining the benefits of Quick Charge is relative and complex, so it’s normal to use simpler simplifications to understand such as Quick Charge 4.0 5 by 5: with five minutes of charging, you gain five hours of autonomy. At least in theory. In plain words, it is approximately four times faster than conventional charging.

To achieve this, Qualcomm uses an INOV (Intelligent Negotiation for Optimum Voltage) algorithm by which the device can determine how much power it needs at any given moment and allow it to optimise the maximum voltage it receives so that the charge is as fast as possible.

Different versions of Quick Charge change the number of voltage and amperage combinations supported by the system and incorporate different technologies for greater efficiency and safety.

For example, Quick Charge 1.0 supports 5V and 2A. Quick Charge 2.0 added 5V, 9V and 12V and 3A. Quick Charge 3.0 reduced heating during charging and Quick Charge 4.0 among many other new features includes support for USB Power Delivery, as recommended by Google.

The technology behind Quick Charge 2.0, the most extended version, is the same behind other quick charge systems such as Motorola TurboPower or Samsung Adaptative Fast Charge, with some possible slight change via software.
