Qualcomm to debut faster Quick Charge 4.0 with Snapdragon 830?

by

qualcomm quick charge 3.0

Qualcomm is set to introduce a new Quick Charge standard on its upcoming Snapdragon 830 chip according to a new report that cites "an accessory manufacturer that wants to remain silent".

Quick Charge 4.0, as it's referred to in fudzilla's report, will allegedly increase 5V charging to 5.6A, providing 28W of power, while there's also said to be a 9V/4A option.

Qualcomm's current Quick Charge 3.0 supports 18W for phones, with voltages ranging from 3.2 to 20V in 200mV increments, and the company will likely retain this approach, as it allows for charging of larger devices when needed.

The company's Intelligent Negotiation for Optimum Voltage (INOV) technology allows for the fastest possible charging speed for specific devices, and is, as the company puts it:

"an algorithm which allows your portable device to determine what power level to request at any point in time, enabling optimum power transfer while maximizing efficiency."

It seems likely some form of optimised INOV technology will be used in Quick Charge 4.0, as the increase in charging capability will have undoubtedly forced Qualcomm to find a way of dealing with potential overheating issues.

There are, of course, other fast charging solutions on the market, with Oppo’s VOOC capable of passing up to 20W of power to the battery, and Huawei’s Super Charge providing up to 22.5W.

But if this latest report is correct, it looks like Qualcomm could be about to exceed the competition in that respect when it launches the new Quick Charge.

Quick Charge 3.0 is currently capable of charging some devices up to 80% in just 35 minutes, according to Qualcomm, so there is likely to be a significant decrease in that charge time on the rumoured new standard.

The report claims phones supporting this Quick Charge 4.0 are expected to launch in "Q1 2017", which is likely when we'll see the first Snapdragon 830 phones hitting the market.

Of course, none of this has been confirmed at this point, so there's no way to know for sure, but stay tuned for the latest as there will likely be more developments very soon.

There's a quick-charging standard built onto the USB3 standard and Google is 'strongly recommending' that OEMs use that instead, saying it may later become a requirement.

So this is likely to die a quick death.

I've turned off fast-charging anyway as it reduces the life of your battery, both day-to-day and lifespan.

yeah thats what i heard. i think fast charging is bad for the hardware causing alot of heat and life of the battery to die quicker...

Out of the hundreds of phones on the market, only two Nexus and two Pixel phones support the USB-PD standard. No company is paying any attention to the inferior standard that Google is pushing. (Heck, even earlier Nexus phones supported Quickcharge 1.0).

The only thing facing a quick death is USB-PD.

'Cept Google can force them to use it.

Inferior how? Less quick charging? To me that means slower fuse...

Let me count the ways:
1. It has much finer control of voltages, the result being it is cooler and more efficient.
2. It uses the data lines to send commands back and forth, so it works with any cable including microUSB.
3. It doesn't use all the special USB-C cable resistors so it is more likely to work without blowing up your device.
4. It is backward/forward compatible. That means a Quickcharge 4.0 charger will work with a Quickcharge 1.0 device (even the old Nexus devices), and a Quickcharge 1.0 charger will quick charge a Quickcharge 4.0 device (not as fast as a Quickcharge 4.0 charger, of course).
This is huge. It means all the chargers you've been buying continue to work with your new phones, and your old phones. The charger in my car works with my MicroUSB QuickCharge 2.0 LG G4, and my son's USB-C Quickcharge 3.0 HTC10. If I had a USB-PD phone, we would be out of luck. We'd need two different chargers, which I can't do in the car without a mess of cables and adaptors.
5. It is a growing standard--Quickcharge 3.0 is already better than USB-PD. Quickcharge 4.0 will likely be even better. Afterwards there will be Quickcharge 5.0, and they are compatible with previous standards so they work with literally 100s of phones. USB-PD is a 'design by commitee' standard, that is showing no signs of any changes, and works with only 4 Google phones.
6. This is for Google: look at the phone vendors. HTC, Samsung, LG, Sony, Asus, Xiaomi, Moto, ZTE,LeEco. If you do this "I dont' care about compatibility with your previous phones or chargers, if you don't go with USB-PD we'll kick you out of Android", Pixel would be the only phone on the market and that would basically shut Android down. Which is why they won't do this. Listen to your vendors and customers Google!!!"

Thanks, good info. You've obviously looked into this more deeply than I have.

My information came from reading this: http://arstechnica.co.uk/gadge...

You make some good points, but ultimately the compatibility you mention is still Qualcomm-specific and, while they're currently pretty dominant, that should hopefully change in the next generation. So for now QC gives you want you want but PD is the longer-term bet.
