quick/fast charging - Sprint Samsung Galaxy Note 8 Questions & Answers

Can someone tell me what the charging specs are? I have seen all kinds of different info on the web. Will the note 8 benefit from a qualcom quick charge 2.0 or 3.0 charger or is the phone's quick charge completely proprietary?
Bob

Benefit, will fast charger at the device's specifications. I use Qualcomm fast charger 3.0 in the car and I get fast charging.
If I remember correctly, Samsung is equivalent to Qualcomm 2.0 speeds.

Does Note 4 quick charge 2.0 support Nexus 6?

Nexus 6 support Qualcomm quick charge 2.0.
Can i use the note 4 quick charge 2.0 to charge the nexus 6?
Is it 9V 1.67A, or 12V?
"Giving the Nexus 6 its juice is a non-removable 3,220 mAh battery. Similar to its predecessors, the battery has wireless charging capabilities, and can supposedly regain 6 hours of power after 15 minutes of charging with a specialized Turbo charger that features Qualcomm Quick Charge 2.0 technology. We'll detail how these stats actually pan out later on in the review."
Quick Charge is a feature of Qualcomm, the manufacturer of the CPU/SoC for the phone. It is a standard for their hardware so any phone supporting Quick Charge will work with any Quick Charge charger. You want to be sure the charger and the phone are using the same version of Quick Charge (v1 or v2). See https://www.qualcomm.com/products/snapdragon/quick-charge for compatible phones and chargers.
I lost my Motorola charger and picked up a Power Partners 30W charger that is listed as compatible and seems to be faster than the Motorola but I didn't do any specific measurements. Typically, I use a Qi (Tylt Vu) changer and don't plug in.
QC 2.0 as mentioned above is a Qualcomm feature. Any certified QC 2.0 charger will work and quick charge your nexus or Note. I don't see he Samsung stock Note 4 charger in Qualcomms site for approved devices but maybe they haven't updated it in a while. It should work just fine. I use a Incipio QC 2.0car charger for when I need s boost on my phone or for road trips. I normally lose battery while using a non QC2.0 car charger running GPS and all of the goodies. In the end any QC 2.0 charger will work on the Nexus 6 which supports QC and you will be fine. They will also work on the Note 4.

[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

Is the fast charger that comes with the Galaxy S7 and S7 edge as fast as IQ 3.0?

So I was wondering if the charger that comes with the phone is as fast as the charger that ANKER sells that is IQ 3.0? One thing I have noticed with my Samsung branded charger is that it says 5V and 9V but the ANKER is 5V, 9V, and 12V... also it says that it is IQ 3.0 and I do know that the charger that came with my S7 seems to be the same as the one that comes with the S6 and maybe even the S5... so are these IQ 2.0 chargers with IQ 3.0 capable phones or are the phones only capable of 2.0 or are we actually getting 3.0 charger?
I'm asking because I am wondering if I should buy the ANKER 3.0 car chager or 2.0 car charger... there is a price difference.
Fast Charge ≈ Qualcomm 2.0
It doesn't matter because the S7 can only takes a max of 15.03W; and since it doesn't support QC 3.0 it won't charger and the intervals between the main voltage steps. The S7 chargers at 9V 1.67A max not 12V, you can refer to the charging test I conducted in my signature for more information
QC 3.0 isn't really any faster than 2.0 anyway. It's just more efficient.

That's not true, if can be faster because it granualrily controls both the current and voltage unlike the large voltage steps in QC 2.0. Since QC 3.0 has more granular control it can charge at the max rate longer without generating as much heat. I would be surprised to see up to a 20% decrease Inc charging time.
In the real world, there's no practical difference in charging speeds. Find some actual tests to the contrary and I'll change my mind. Maybe in the future there will be phones that really take advantage of QC 3.0, but nothing out there now does.
Why are people so caught up on this qc 3.0 stuff? It's just so stupid.
First of all 3.0 isn't really a speed improvement over 2.0, it's not even significantly faster.
Second, fast charging or charging under high temperatures, or discharging your phone deeply before charging, all associated with the use of fast charging. They all kill your battery faster than usual, most of the people here are too scared to drop their s7 or dunk their s7 in water yet at the same time everyone is eagerly trying to kill their battery as early as possible with fast charging.
If you want your phone to last, use slow 1 amp chargers, wired, and charge often.

If you understand how this charging process works then you can see it's advatanges. I haven't seen anyone do a real world test yet, and if I knew someone with a QC 3.0 enabled phone I would test it. I don't see how it won't be faster given the higher efficiency it will have while charging. Heat from charging creates resistance, so if you lower the what you can increase the efficiency which is more or less what it does by granularly controlling the voltage in 200mV steps instead if the normal 5V/9V/12V large steps.

[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...
Sent from my SM-G920P using Tapatalk
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

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.

USB-C PD vs Adaptive Fast Charge?

Does anyone happen to know which one charges these phones faster? If I'm not mistaken, Adaptive Fast Charge is basically QC 2.0 right? So wouldn't USB-C PD be faster?
My phone hasn't been shipped yet, otherwise I would test it out myself.
The phone only supports Samsung's Adaptive fast charging, so using a USB-C PD charger won't make a difference.
It also supports Qualcomm Quick Charge 3.0 as fast charging, just like the S8 and S9s.

Why would I go through all that just to prove what we both already know. You even said it yourself that it charges as fast as wall adapter. Wall adapter that ships with the phone is NOT 3.0, so what are you trying to prove exactly? Wall adapter charges at 2.0 amps.
Please stop misinforming people, it's nothing personal, just trying to state the facts. See attachment

You need to contact Samsung and let them know this, I'm not sure they're even aware of this feature.
chill guys, its cause QC is backward compatible.. so using QC3.0 you will get fast charging up to QC2.0.. not too sure about USB-C PD but i can confirm when using USB-C PD charger, you will get fast charging as well.. not too sure which is faster.. probably the same if the charger can charge up to 15W which is the official max charging speed for S10 btw.
edit: i use the same USB-C PD charger for nintendo switch and S10+

I called chief, he said that we were chill, and that the phones charging capabilities was already stated in this thread. Thanks tho
Obviously Quick Charge 3.0 would be backwards compatible with Quick Charge 2.0. There's no such thing as "Quick Charge 3.0 only." If there was, boy would we have a lot of fried/exploded devices as they received more current than they were rated for.
Haha did you guys even look up what QC 2 and QC 3 were? They aren't that much different, just the step size. Both have a max of 18 W. You would need a volt meter to prove the phone was QC 3 compatible, showing it charging at a voltage that was not near 5, 9, or 12 volts. As far as I'm aware, the S10 either charges at 5V with Fast Charging disabled, or at 9 V if fast charging is enabled. That would adhear to the QC 2 spec, not the QC 3 spec, since it can't do voltages between 5 and 9. If the S10 gets an update for 25W charging, I believe it would charge at 12 V. Still, only QC 2 compliant, but not QC 3.
USB-C PD can go up to 100 W. I think 45 W and 90 W for laptops is pretty common. The Huawei P30 Pro can supposedly charge at 40 W.

Guess they were having a hard time understanding that QC 3.0/2.0/whatever give the fastest charging speeds that S10 can handle.
On my S9 with Nintendo Switch USB-C PD charger I couldn't get 15w, just 10w (aprox. 5v and 2a).

Thats likely because you have fast charging disabled. USB-C PD chargers should be capable of charging at 9V 1.67 amps (15W) the same as any QC 2.0 or QC 3.0 or Adaptive Fast Charging capable device. They are just different standards.
Haven't tried using the original charger yet, but my s10 charges on my usb pd capable charger for about 1hr and 20 from 15% to 100%
I'm able to charge up my S10 with a QC. 3.0 power bank and car charger in about the same time as the stock wall charger.
