Quick Charge 3.0: The Latest Generation of Android Device Charging Technology

Quick Charge technology which was developed by Qualcomm is not exclusive to Android devices however today most of the licenses of this technology appears to be skewed heavily on the Android side like the Samsung Galaxy, Sony Xperia, HTC, LG lines of the world. While Apple also has rapid charging technology, if you want to use Quick Charge 3.0 you need to have a Quick Charge 3.0 AC adapter or power bank which supports it.

If your phone currently doesn't support Quick Charge 3, if it's an Android devices most likely it supports QC 2.0, especially if it was purchased in the last 2 years. For more information on Quick Charge 2.0, check out my article here.

In an article by Robb Triggs called, "Quick Charge 3.0 explained: what you need to know (Update: video added)" he explains is a great way what Quick Charge 3.o is and then the fundamental difference between all 3 versions of Quick Charge currently:

Quick Charge 3.0

Qualcomm boasts a fourfold increase in charging times over conventional chargers with Quick Charge 3.0, up from the 40 percent speed increase offered by its first generation technology. However, one of the interesting things to note is that Qualcomm isn’t touting massive increases in charging times over version 2.0, instead the company is focusing on improved efficiency this time around.

The major new feature with 3.0 is INOV (Intelligent Negotiation for Optimum Voltage), which allows for a fined tuned power output and a more optimized charging cycle. Firstly, different batteries require different charging voltages. Version 2.0 supported four modes at varying power levels, 5 volts/2amps, 9V/2A, 12V/1.67A, and a 20 volt option. Quick Charge 3.0’s INOV communicates with the device to request any voltage between 3.2V and 20V at 200mV increments, allowing for a wider selection of voltages. Read Full Article...

As I mentioned earlier, QC technology is licensed and many people think that a device needs to have the Snapdragon processor in it in order to support QC. This however is not true. There are a number of Samsung devices which use their own processor and still support QC so don't be afraid to get the device you want, most likely it will have this technology in it which is becoming a standard on the Android side. Further, it is rumored that Apple's "fast charging" technology is licensed from Qualcomms so while they may not call it Quick Charge and they have different specs for the technology, it very possible that all devices have similar tech.

Since my site is based around USB charging and in particular portable charging technology like a Samsung power bank, keep a look out for power banks and 3rd party AC adapters which also incorporate the latest Quick Charge version. Especially if you own an Android based device, these would be the best choice for you if you are considering a travel charger or portable battery pack.

In a post by Ron Amadeo titled, "Qualcomm Quick Charge 3.0 goes from 0 to 80 percent in 35 minutes," you can see how quickly this technology can either top off your device or get a low powered device back on its feet...

Qualcomm's latest line of SoCs have a new charging feature, dubbed Quick Charge 3.0. The new standard, which will ship on the Snapdragon 820, 620, 618, 617, and 430 next year, promises to take a phone battery from 0 to 80 percent in about 35 minutes. Qualcomm says the new charging standard will "improve fast charging up to 27 percent or reduce power dissipation by up to 45 percent when compared to Quick Charge 2.0." provided vendors use Qualcomm's "advanced parallel charging configurations."

The new standard uses an algorithm called "Intelligent Negotiation for Optimum Voltage (INOV)" which lets the device continually request a power level from the charger, from 3.6V to 20V, in 200mV increments. Quick Charge 2.0 only offered four charging voltages, but 3.0 offers 82 different voltage "sizes," which Qualcomm says results in "minimized losses, increased efficiency, and improved thermal performance."

Quick Charge 3.0 is backward compatible with versions 1.0 and 2.0 and is connector-independent. You'll need a new phone and a new charger to take advantage of the higher speeds.

Since charging our devices is an inevitable part of our mobile life, and our expectations for charging has changed from multi-day to charging it multiple times a day, we should all be using the latest charging technologies.
