What Is Qualcomm Quick Charge 3.0 And How to Choose it?

As smartphone batteries are getting bigger and more reliable in performance, their charging times are gradually getting shorter. Modern smartphones use fast chargers that equip a smart circuit responsible for fast charging. This circuit is controlled by a charging protocol that manages the voltage and power while charging your phone. Such a charging protocol is Qualcomm quick charge 3.0 which is used by many smartphones, USB wall chargers, and power banks. If you don’t know about this charging protocol, then sit back, relax, and keep reading this article for the related info.

What Does Qualcomm Quick Charge Mean?




So, what is Qualcomm quick charge? Quick charge is a charging standard developed by Qualcomm for smartphones, power banks, and wall chargers. With this technology, a battery charging device can work at varied voltage ranges to charge batteries much faster than conventional charging. Today, smartphones have large batteries for which normal USB charging isn’t enough. Let's say you have a 5000mAh smartphone. To charge a battery this big, a 5W USB charger may take more than 6 hours.

Keeping your smartphone plugged in for that long doesn’t make any sense. In such a situation, Qualcomm’s quick charge comes to save you precious time. Qualcomm’s fast charging standard cuts the conventional charging time short by many folds. You can expect to get a 3000mAh battery fully charged in less than an hour. Also, 15 to 20 minutes of quick charging provides enough fuel to your smartphone to keep it up for an entire day.

How Fast Is Qualcomm Quick Charge 3.0?

When it comes to charging your smartphone battery, Qualcomm quick charge 3.0 is designed to charge most smartphones' batteries to 50% in about half an hour. Now, it shows that Qualcomm's quick charge 3.0 version is 38 percent more efficient than quick charge 2.0 and twice as fast as quick charge 1.0. It is also four times faster than a 5W (5V and 1A) USB charger. To charge 50 percent of a 2750mAh lithium-ion battery, quick charge 3.0 only takes 30 minutes with a max power of 36W.

How Does Qualcomm Quick Charge 3.0 Work?

The quick charge 3.0 enabled wall charger to communicate with the smartphone (when connected over USB) with Qualcomm quick charge 3.0 charging protocol. The smartphone decides how much power it requires to charge the battery at any instant, then sends this information as a digital signal to the wall charger. On receiving this signal, the wall charger regulates the voltage and current.

When the battery is at zero level, the smartphone operates at a high voltage (less than or equal to 20V). As the battery gets charged, the voltage slowly drops. This communication remains active between the two devices until the battery gets fully charged. The gain and drop in voltage level don’t overheat the battery while charging. The battery temperature is actively monitored by the power delivery circuit which prevents overcharging and the risk of explosion.

Qualcomm 3.0 vs 2.0 - Where Is The Difference?

The main difference between Qualcomm quick charge 3.0 and 2.0 is the power and voltage management. Qualcomm quick charge 3.0-certified smartphones use Intelligent Negotiation for Optimum Voltage (INOV), a charging protocol that lets your smartphone select any voltage between 3.2V to 20V. So, your smartphone can target a wide range of charging voltages with 0.2V increments without overheating the battery. While quick charge 2.0 operates at three variable voltages of 5V, 9V, and 12V only.



Why You Should Consider Qualcomm Quick Charge 3.0?

There are just a few of the benefits that come with having Qualcomm Quick Charge 3.0 technology in your device as follows,

1. Fast and Efficient Charging: Quick Charge 3.0 is a fast, efficient, and reliable way to charge your device – up to four times faster than a standard charger. The technology intelligently adjusts power output for devices that support it, allowing them to charge significantly faster than other methods.

2. Power Savings: With the Qualcomm Quick Charge 3.0 technology, you can save energy while charging your device since it only uses the amount of power needed at any given time. This allows you to save battery life and conserve energy when your device needs extra juice.

3. Compatibility: The beauty of this technology is that it’s compatible with any USB-C or USB-A cable, so you don’t need to worry about having the right one for your device. This makes it possible to use Quick Charge 3.0 with almost any device you own, regardless of whether or not it has an official Quick Charge charger.

4. Temperature Control: Extreme temperatures can be harmful to your device and its components – especially when charging at high speeds. With Qualcomm Quick Charge 3.0, the technology has safeguards in place that will detect the temperature of the device and adjust power output accordingly, allowing your device to charge safely without overheating.

5. Universal Support: Quick Charge 3.0 is supported by a variety of devices including Android, Windows 10 Mobile, iOS, macOS, and more – so no matter what type of device you own, you’ll be able to take advantage of this technology. Besides, wall chargers and power banks also equip Qualcomm quick charge 3.0 – see Anker 337 power bank. Plus, the technology is constantly being improved and updated, so it’s always up-to-date with the most advanced features.



From faster charging times to better temperature control, if you’re looking for an efficient way to power up your device without sacrificing safety or performance, then Quick Charge 3.0 may be just what you need. If you bought your smartphone somewhere near the end of 2017 then it is certain that it supports Qualcomm quick charge 3.0 even a Qualcomm quick charge 4.0 or 5.0. Anyway, we hope this article will help you better understand and select Qualcomm Quick Charge 3.0 to enjoy safe and fast charging in life.

FAQ about Qualcomm Quick Charge 3.0

What If Your Smartphone Doesn’t Support Qualcomm Quick Charge 3.0?

Most modern smartphones equip some fast charging technologies. For example, OnePlus uses dash and warp charge, Oppo uses SuperVooC, Samsung uses its adaptive fast charging, Huawei uses supercharge, and Motorola uses turbo charge. So, you may still enjoy fast charging even if your device does not support Quick Charge 3.0, which may vary not that much in speed. Besides, you can also depend on your official charger or any other certified Quick Charge 3.0 power bank like Anker 337 to charge your device.

Do Smartphones With Other Fast Charging Standards Support Qualcomm Quick Charge 3.0?

Maybe not! Those smartphones featuring Qualcomm Snapdragon chipset may support Qualcomm quick charge 3.0. While other smartphones may have their own fast charging standard and don’t support a Qualcomm-certified charger. For example, OnePlus uses dash charge as a proprietary fast charging standard for their smartphones. Charging a OnePlus phone with a Qualcomm quick charger may cause it to shut down or stop charging.

Does Fast Charging Affect Battery Life?

Fast charging does not affect the performance of the battery. While the heat generated when charging may damage the battery and smartphone. So it's better to use certified fast chargers, especially those official fast chargers or Qualcomm-certified quick chargers designed to work with your smartphone. These chargers are the best way to keep the battery safe and performing till its stated lifespan.
