The different generations of fast charging created by Qualcomm

For the standard battery, the charge is generally done in more than 3 hours. As for the external fast charge battery , the process is completed a little less than 1 hour 30 minutes. Over the years, the manufacturer of mobile processors Qualcomm has been one of the first firms to innovate in the field. She has created several increasingly efficient versions of Quick Charge (QC):

Quick Charge 1.0

Offering equipment for most high-end smartphones, Qualcomm took the opportunity to establish its technology: the Quick Charge. Version 1.0 of this technology is coming to the fore in 2013. In view of the results obtained, we can say that a real revolution was underway.

The principle of operation of the Quick Charge 1.0 is rather simple. The technology uses the basic parameters of classic fast charging, namely voltage and intensity. However, it offers a peculiarity. First of all, the Quick Charge 1.0 varies the speeds. When the battery is completely dead, the cadence is at maximum for fast charging. When the battery has received a sufficient amount of power, the rate is reduced so as not to damage it.

In addition, the Quick Charge 1.0 is only compatible with Qualcomm’s Snapdragon 600 processors. It offers 10 watts charging, or 5 volts on 2 amps. It should be noted that at this time, most manufacturers offered a lower loading speed. The standard was 5 watts, or 5 volts on 1 ampere.

Quick charge 2.0

The second generation of Quick Charge made its appearance in 2014. At that time, Qualcomm then offered a maximum power of 18 watts distributed as follows:

Most smartphones equipped with the Snapdragon 200, 400, 600, and 800 series are compatible with Quick Charge 2.0. However, many phone manufacturers are still hesitant to make their devices compatible.

Quick Charge 3.0

Released in 2015, the third installment of Quick Charge technology offers great compatibility with many Snapdragon processors. In terms of its characteristics, it has the same maximum power as its predecessor, 18 watts. However the voltage and the intensity vary according to the processors.

The real innovation of this technology is the central functionality INOV (Intelligent Negotiation for Optimum voltage). It consists in regulating, with a precision of goldsmith, the power of charge sent. In this way, the charge cycles are optimized. Here, the charging device and the charger exchange information to define the required power. In addition, the two peripherals agree to limit energy losses. The best fast USB chargers from manufacturers such as Samsung or Huawei already integrate this system.

Quick Charge 4.0

This is the last version of this technology which appeared in 2016. Quick Charge 4.0 does not offer a wide range of innovations. This is just an improvement from the previous version. For this generation, the designers of Qualcomm have concocted a more efficient INOV algorithm.

The Quick Charge 4.0 offers poor compatibility compared to its predecessors. At its launch, the technology was only available on the Snapdragon 835 processor.

The advantages of Quick charge

When you want to use your external fast charging battery , it is obviously to benefit from the acceleration of the recharging. Indeed, throughout its development, this technology has reduced as much as possible the time required to top up the batteries. We went from a charging time of 3 hours to 60 minutes.

The other advantage is the preservation of the integrity of the material used. Today, the price of a fast charging external battery is quite affordable despite their quality. Contrary to appearances, Quick Charge technology does not overheat most smartphones. This is because despite the fact that the power is higher than the normal charge, the li-ion battery will not be compromised.

In addition to these two advantages, it reduces the risk of energy loss. Since this process promotes powerful and fast charging, there is less energy loss.

Some limitations of fast charging

Charging technology remains a dazzling advance in the world of smartphones. However, it has some limitations. Already, the Quick Charge is not available for all smartphones.

In addition to the compatibility of certain processors, the technology of a fast phone charger requires more power than a normal charge. This can overheat some phone batteries and thus shorten its lifespan. The question is, do you use a phone for 5 years? Because it is after this time that the internal battery of the phone can be really affected by the fast charge.

Is my smartphone compatible with fast charging?

Fast charging technology is not yet democratized on all smartphones, especially entry-level and mid-range ones. Only certain phones and tablets equipped with Qualcomm’s Snapdragon processors are compatible. Rest assured if your smartphone has at least one USB Type-C port with fast charging.

In addition, Android is the only operating system compatible with fast charging. To benefit from it, you must buy a fast charge external battery in order to quickly recharge your phone even outside.
