Qualcomm announces Quick Charge 4.0+ featuring three new enhancements
by Cosmin Vasile / Jun 01, 2017, 3:24 PM
It's been six months since Qualcomm introduced its new Quick Charge 4.0 technology, which faster charging than its predecessor, allowing a smartphone to go from empty to 50% in just 15 minutes.
Well, it appears that Qualcomm has managed to stuff in new enhancements to its quick charge technology, but not so many or so important to call the new product Quick Charge 5.0. As such, Qualcomm unveiled the new Quick Charge 4.0+, which mainly offers three significant improvements over the last year technology.
The first one is called Dual Charge, which is present in previous versions of the technology but is now stronger than even. With Dual Charge, the charge current will be divided allowing for lower thermal dissipation and reduced charge time (up to 15%).
Then, there's Intelligent Thermal Balancing, which conducts current via the coolest path autonomously, thus eliminating hot sport for optimized power delivery.
Lastly, some advanced features have been implemented as well, which are meant to enhance safety during charging. For example, Quick Charge 4.0+ can monitor both the case and connector temperature levels at the same time, which should prevent overheating and short-circuit, or even damage to the Type-C connector.
Thanks to these three new improvements, Quick Charge 4.0+ can charge a device up to 15% faster, and it's 30% more efficient when compared to Quick Charge 4.0.
According to Qualcomm, the first smartphone to include the new Quick Charge 4.0+ technology is the Nubia Z17, which was unveiled earlier this week. The handset comes with a 3,200 mAh battery, a Snapdragon 835 processor, as well as 8GB RAM and 128GB storage.

Quick charge is nice but double or triple battery capacity to begin with would be nicer. I wouldn't mind charging overnight if my device had a 10-15k mAh battery.

I guess PA miss the memo from Google. They said to not use QC 4.0 and USB-PD is the future of Android. "To try aiming for quick charging unity, Google is telling Android OEMs to ditch Qualcomm's quick charge implementation and switch to USB-PD. Google seems really serious about this, as it has started to write quick charging language into the Android Compatibility Definition Document (CDD) that every OEM licensing Google's Android apps must follow. The new clause in the Android 7.0 CDD reads:""Type-C devices are STRONGLY RECOMMENDED to not support proprietary charging methods that modify Vbus voltage beyond default levels, or alter sink/source roles as such may result in interoperability issues with the chargers or devices that support the standard USB Power Delivery methods. While this is called out as "STRONGLY RECOMMENDED", in future Android versions we might REQUIRE all type-C devices to support full interoperability with standard type-C chargers.' Source ars technica

From 8 Nov 2016http://www.androidpolice.com/2
Qualcomm then announced QC 4.0 a week laterhttp://www.anandtech.com/show/ 10846/qualcomm-announces-quick-charge-4
Finally adding USB PD compatibility

Your 4K battery doesn't last all day? My 6S+ lasts 1.5 days on average without a charge. Overnight charging (when I am asleep and not using my phone) works perfect. If I have 45% left at the end of the day to use for the next day, I wake up with 44% battery if I don't charge. Same went for my Note 4, minus the great standby time the iPhone has.

I was under the impression that when said user above said: "Quick charge is nice but double or triple battery capacity to begin with would be nicer. I wouldn't mind charging overnight if my device had a 10-15k mAh battery.", ..that he wouldn't care about quick charge if phones shipped with better batteries. Contextual relevance when reading is hard I guess?

Except no phones that have the 835 processor has supported it so far. So this is pretty much a loss for this year.
