[Q] Quick Charge 2.0 confusion

Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

I'm using the franco kernel at the moment and as far as I can tell it doesn't have any options related to charge speeds. I'll look into other kernels.
Thanks for the info!

Why would you need options relating to change charge speeds? Qualcomm quick charger works on any kernel, if you're talking about USB fast charging, it's already enabled in Franco kernel.
There isn't a need to switch to other kernels.

@zephiK You misunderstood my question. The problem I'm looking to solve is the slow charge rate from the chargers in the original post.
To add to that. My macbook also charged my old galaxy phone @ 2amps but with my n6 only does 500mA.
Nothing wrong with the turbo charger

Laptop USB ports at limited to 500mah output unless its a dedicated charging port with USB 3.0 then It can push 1.6A so I don't see how that's possible to charge at 2A from a laptop.

@Pilz this is irrelevant. My 2014 macbook pro charges my old phone much faster than the nexus 6.
Refer to the original post for the topic at hand

Quickcharge 2.0 devices uses the data pin on usb to determine if the charger connected is a quickcharge 2.0 charger. The devices you are using do not have this capability so they charge slower. I do not think this can be changed kernel or phone side.

Thanks! I guess I'll have to replace the chargers/battery

I could be wrong S5 I looked up uses usb3.0 right? Does your macbook have usb3.0? If so then the usb 3.0 port can supply more current when detected being a usb3.0 device by your computer and ever more so it is possible for the mac to output a little more current. Can you plug in the S5 then open system profiler to look at USB device tree to see current being delivered? The nexus 6 only using usb2.0 would not get the same treatment by the comp and only receive the max standard of .5 A.
There are many details about the actual max current that can be supplied by the computer's ubs port that I don't know when they are applicable I've just stated reading so I'm not sure why you can get 2.0 A on your S5 and not less, since there are standards that set the max current. Even more complicated is that under certain conditions macs have their own heirarchy of supplying more current to some devices if they "say they need" more current and even then there are limitations. So again I'm not sure what is at play exactly, that determines why the S5 gets more than usual. The .5A is normal for current output on USB 2.0 in the nexus6.

I actually got this in the mail yesterday, and the wall chargers works great...Havent have a chance to test out the car one though!

That doesn't make sense which is why I went into some detail about laptop or any computers USB ports. I unfortunately had a MB Pro and hated it, and it never charged any of my phone a at 2A including my wife's old S5. I don't have it anymore so I can't test it again to verify. The person I quoted below explained it a little better than I did.

Qualcomm doesn't post every certified charger on their website. In would email the manufacturer and ask for their certification or a picture of it which most will show you assuming on they're legit.

It is technically incorrect for the phone to accept more than 1 amp on a 5v charger. The quick charge *protocol* negotiates a non-standard charge voltage (up to 12 volts!!!). Quick charge is actually BAD FOR YOUR BATTERY! The higher the current, the greater the temperature. The greater the temperature, the lower the battery life.
Unless you *need* it to charge that fast in an emergency, don't.
I've never even plugged in the charger that came with mine, and I don't intend to.

I've used QC 2.0 since I bought my phone during long days and my battery life is just fine. My battery is cooler during QC than when using qi charging so I disagree. Generally speaking you're correct, however the battery would need to get hot and stay hot which is doesn't. QC 2.0 tapers off the voltage and current overtime to a more "normal" amount. Your argument is an old and doesn't always pertain unless your phone is constantly hot.
You're battery degrades overtime anyway and any heat could speed that up. I used to live in AZ where it gets to 120+[°F] in the summer which is hotter than my battery ever gets even using QC from 1% battery. Quick charging won't hurt your battery any more than normally charging it will. There is a cut off for the temperature it will let your battery get before it drops voltage or amperage which will work whether the what is from charging or the environment you are in. As I stated above qi charging will make your battery heat up more (in my case it does) I will post screenshots to back that up if you would like.
Lastly no one is expecting a battery to last 1-2 years without losing capacity so why worry about it? Your phone is warrantied for at least 1 year (I have moto care on top of the regular warranty) which will cover any battery issues. There's no need to panic or make an issue out of nothing.
Now can we please let this argument die? I keep seeing it and its getting rather old. Even if it does (which I'm not saying it does) degrade slightly faster its not a big deal for the aforementioned reasons. Let's get back on topic here people

Which FAST charger I should order for my new Huawei P9

Hi to all
Just ordered a new EVA-AL00 from eBay last night. I am living in Canada. May I know which charger I should order to take advantage of the quick charging capability of the P9 ?
Is P9 using QC 2.0 or 3.0 ?
Please kindly advise ASAP.

HI
wrong! fast charging is supported by huawei fast charger
but only with this charger i tryed with asus 5v2A/ 9v2A but dont working

anyone who can provide a link to where i can buy one with an eu plug?

I'm considering buying this phone over the S7 (although still undecided) and I still don't get the battery thing (charging or battery life, I get people telling me all sorts of contradictory things that I'm having a hard time to fact check). That 9V/2A charger doesn't come with the phone, right? How much faster is that Huawei charger compared with the 5V that comes with the phone and what is it called since I can't find it on their site or anywhere? Is that the Mate 8 charger?

Yes it's mate 8 charger

Well, no EU plug still available. But it will be later I think. It is not QC 2 or 3, it won't work. Search for "Huawei 9V 2A Charger".
The result should be like this: http://www.ebay.com/itm/Original-9V...hash=item280f7d97a4:m:mNQwKZr7I5KHReS9CA2RwkA
As I metioned, no EU plug yet, so via adapter only.

The photo shows it is 5V 2A charger, so it is a standart, not a Huawei Quick Charge (9V 2A).

hi i never look before
i just charge now at 21h59 and 46% i will post the result at 100%
Edit: 100% at 23h02 ( 54% in 1h00 approximatly) but when i have the time i will try a full charge because the fast charge is more active at the start and midle of charging

With this Aukey charger I got from 5 to 95% in about 90 minutes

It's fine, it will charge as a standard charger at 5V. I would have to brush up my Ohm's law but I don't even get why Huawei's standard charger on the P9 has 2 Amp electric current value. What matters is the voltage going into the battery and you don't need a 2 Amp charger to give you 5 volts, a regular 1amp will be able to do that. The only difference I know is that 5V at 1 amp are 5 watts and 5V at 2 amps are 10 W. But that has only to do with resistance, I think, a battery isn't fed on watts?
I'm really on the fence about this fast charging thing now. I never got it. Qualcomm's has its QC 2.0 tech but a Motorola charger is faster than any other. An S7 Edge with amuch bigger battery charges as fast as an HTC 10 and the Edge has a 2.0 QC and the HTC is 3.0. The G5 is also 3.0 and charges way faster than the HTC, even compensating for the different battery capacity. And I own a G2 which has no fast charging at all and will charge from 0 to 100% in less than 2 hours on a 5V generic charger, which isn't very far off the times I see with 3000mah batteries and Quick Charge 2.0 or 3.0... Why these differences?? No idea... Somehow I think battery chemistry has a lot to do with it (it does in the RC and electronic cigarette world) but I never see anyone addressing that.
^^^^sorry for the rambling, just thinking/writing out loud

Nearly right! A little analogy may help... Think of Voltage (V) as the diameter of the water tap, Ampage (A) as the speed of the water through the tap and Wattage (W) as how quick you want the bath the taps are filling!
So you can see, a small diameter tap but high water speed will still not fill bath very quickly, neither will a big diameter tap and slow water speed...you need both together. So 9V2A should charge quicker than 5V2A (18W compared to 10W).
As I understand it the P9 will accept charging at 9V and 2A (their Fast Charging) giving max 18W input so a 9V2A charger should give the best results (which is what the P8's fast charger is)...and what the qualcomm quick charge 2.0 (and 3.0) spec can provide. Now i'm not saying the P9 is a qualcomm quick charge phone, it's not, but my QC2.0 and 3.0 car chargers certainly charge my phone quicker than the included mains charger! So i suspect that the car chargers are providing 9V2A to the phone.
Whether this means any 9V2A charger would do......I don't know

[Q] Is Quick Charge 3.0 supported?

I have read that QC 3.0 will be supported since the Qualcomm 820 supports it. But, the S7/edge has the same processor and only supported QC 2.0. Any ideas?

Don't think so...

It's confusing. The Note7 has a different Adaptive Fast Charger than earlier Samsung phones. The Note7's charger is 12V, 2.1A while the Note5 and S7-series chargers output 9V, 1.67A . QC 2.0 supports a maximum of 2A and works with 5, 9, and 12 volt chargers. Qualcomm's website lists the Note7 as a Quick Charge 2.0 device. So why did Samsung upgrade the charger output? With QC 2.0 maxing out at 2A they could have introduced 12V with the S7-series as there's no USB-C requirement or benefit on 2.0. Maybe Samsung moved from USB 2.0 to USB 3.0 on the Note7 which may have an impact.
So like I said it's confusing. But with a higher output charging adapter and the Note7's assumed ability to accept that higher output you'd have to assume it'll charge faster than the S7-series. Even on QC 2.0 if Qualcomm's website is right. I guess we'll find out more when a more tech focused site like Anandtech and GSMArena do their full testing.

I plan to test it out using my inline USB multimeter that records data and sends it to my PC. Once my Note 7 gets here I'll run some tests assuming I'm not too busy at work

I doubt it. Samsung likes to use their own.

It does if you plug in a "qualcomm" charger and the phone doesn't identify it and use the fast charge or vice versa.

It doesn't because Samsung's adaptive fast charging is just QC 2.0 like it was on the S7/S7 Edge. I thoroughly tested mine with a variety of QC 2.0/3.0 chargers a while back.

What is the voltage you receiving ? 9v,12v or 5v and amp as well ?

I checked it too. During charging, the charger regulates between 12 and 9 V voltage and 1.5A at 12V, 2A at 9V and 2.2A at 5V. When charging with the QuickCharge charger the biggest differences can be seen at the time of charging the first 40%, while in the later phases also large differences are visible, but not on such a large scale.

Original Charger vs Quick Charger 3.0

Original charger hits 1700mA while Quick Charger 3.0 hits 2300mA. Screenshots below. I'd like to know if anyone else has done a similar test so we can compare results. I bought a (supposedly) Quick Charger 3.0. The results are obviously better but I'm not sure if its supposed to be higher or not.

SD660 can even do Quick Charge 4, but for Mi A2 officially only in india.

Global version might need a patch.

This this means that we can use Quick Charger 3.0 or 4.0 without harming phone's battery?

Exactly! i really don't know how that works.. Does that mean that the original charger is somehow a quick charger?

Empirical evidence suggests that Oreo seems to show "charging rapidly" anytime amperage is above 1 amp or so, it has nothing to do with using a quick charger or the original brick supporting quick charge.

No guys. I found:
0 - 999 mA = charging slowly
1000 - 1499 mA = charging
>> 1500 = Charging rapidly
Not sure if MiA2 use the same parameter.

Nice, I was gonna say 1500 cause that was kind of what I remembered but wasn't totally sure. 1.5A is typically rapid enough to charge with relative speed even while the device is in use which is probably why that was picked. I agree that they should probably provide a reading above 2A to signify quick charging as "charging rapidly" is definitely confusing.
