[Q] Is Quick Charge 3.0 supported? - T-Mobile Note 7 Questions & Answers

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 doesn't matter what Samsung calls it they're still using Qualcomm quick charge

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.

Samsung Galaxy S6 Edge Charger

I just pre-ordered my galaxy s6 edge on amazon and i have a couple of questions:
1) Will the "Nexus Wireless Charger" sold by google work with my new S6 or i'll have to buy a new wireless charger???
2) Does the "Car wireless charger" sold by samsung charge slowly compared to "wired charging"??
3) I just checked my local samsung online store and only this car wireless charger (Model number: EP-HN910I) is listed. It also states it's for the galaxy note 4.
What is the difference with the one sold on the us online store (Model number: EP-HN910IBUSTA)??????
4) As for "wired car charger" i found this one by samsung (Model number: ECA-U21CBE).... will this charger charge the galaxy s6 as fast as possible in my car or there's something better??
Thanks in advance

Yes, the Nexus charger uses Qi so that should work with the S6.

Yes, Qi charging is slower than wired. Qi is currently limited to 5W (1A) for phones and as far as I know Samsung arn't doing anything to go higher than this. Samsung's car charger should be similar to your nexus charger. By wire it supports fast charging (~15W), but any decent 10W (2A) charger will be twice as fast as wireless.
Edit: I obviously havent tried this with the S6 and Samsung's charger, but my experience in the past is a good Qi charger will slowly charge a phone while you are using GPS with screen brightness turned up. It is slow though, the charger is barely providing more power than the phone is using.

That is a 2A charger. (10W).
The phone supports faster but I am not sure if there is a suitable car charger yet. There may never be because Samsung's support page says fast charging only works when the screen is off so it is probably pointless in a car.
wireless charging is much slower.. but not only is it slower, it heats up the battery more and puts more wear on the battery as well due to heat and wasted energy involved with wireless charging.
for car charger i would recommend the RavPower, it puts out 2.4A per jack and you can charge 3 deices at the same time and use your own USB cables.
http://www.amazon.com/gp/product/B00OT7PJ60/
or the Anker, includes 1 cable, but 1 less port
http://www.amazon.com/gp/product/B00D82O68Y/
they also sell it for 2 bucks cheaper without the cable... both chargers have great reviews, and both will charge the phone as fast as possible.
Thank you very much for both of your help!!!
You cleared all my doubts!!
I just ordered the anker car charger from amazon!!!
Thanks again.

it will charge, but unless you have a Qualcomm 2.0 phone any other phone you plug in will just "adapt" to the fastest charge rate in this case will be 5V @ 2.1-2.4A.

did you measure the Amps and Volts? anything above 2A is "fast charge"
in order for it to be the "fast charge" it has to be @ 9 Volts not the typical 5V.
not saying the S6 won't work with Qualcomm, because i don' t have a phone to test the amps, but mostly only phones with Qualcomm chips are the ones that support Qualcomms own "fast charge" mode, and samsung S6 has no Qualcomm. one would think it would be a license patent thing that wouldn't be compataible with just any device..

Does it actually output 2A to the phone? The sticker on the back says "Input: 2A", but it is normal for the transmitters to have a higher input than output current. I think they will have just put 2A to match the output rating of the wired charger it goes with. The S5 charger pad also says "Input: 2A" and that was a normal 5W pad.
The Samsung S6 Pad is listed on the WPC page as a "Lower Power Transmitter", which means 5W max. They did recently increase the Qi standard to 15W, but that is only a draft specification (called Medium Power) and they are not listing any products available with it at the moment. (And of course, it would be at least 3A in).
I am not saying it definitely doesnt support fast charging - TI have a transmitter/receiver solution which is 10W but also supports Qi 5W (though that needs 12v in so isn't used here). If they supported something like this though I am sure they would have mentioned it. Plus the need to support PMA on the receiver would have limited their choices of receiver chip. I wouldn't be surprised if they are using TI's solution, which is 5W.

I wondered that as well, though I wasn't able to actually find any hard evidence one way or another. Even the listing for the item on Best Buy doesn't mention it (or at least it didn't last night). Might just have to take the wait-and-see approach with this one. Taken at face value though, the possibility is there. My gut says you're probably right though.
i have a spare motorola turbo charger (qualcomm 2.0 quick charger) that came with my droid turbo. I preordered the s6 edge and was wondering if the turbo charger will work with fast charging of the s6 edge? just want to clarify. thanks

Yeah if fast charging is what you're looking for that's definitely the way to go.
The alternative wireless solution is to simply get a wireless power bank, but of course that still won't charge quickly; though they are less cumbersome.

[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!

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.

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

quick/fast charging

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.

How do we choose a USB C cable that takes advantage of Mi 8's Quick Charge?

Since we have QC 4.0, how do we make sure that the USB Type-C cables we buy will maximize the fast charging feature?
I'm looking to pair it with a right wall charger inspired by this other thread (i.e. a wall charger that truly supports QC 4.0 since the one in the box supposedly is just QC 3.0 certified).
I'm finding it difficult to find QC-certified cables, let alone ones that say they specifically support QC 4.0.
Any tips on what specs to look out for?
Look out for type c cables that support power delivery, those an handle the high wattage for qc 4.0. If you want fast charging speeds, looking out for chargers capable of outputting 30 watts. i.e 3amps x9v= 27w
Nah I think you should wait for xiaomi to release a QC 4 charger & cable. Because USBPD is still a mess.
Some interesting charts you can see in here https://www.androidauthority.com/state-of-usb-type-c-870996/
As you can see same phone charged different speed when they use different chargers & different cables. (or same charger with different cables)
Mi 8 won't be different, so want for xiaomi to release a QC 4 charger & a cable to take advantage of the QC 4 / 4+ technology.
I went ahead and got a Tronsmart W3PTA. Really pleased so far!
It supports QC 3.0 (nothing faster than the stock charger I know)... But the main value for me is having a total of 3 USB ports and the right socket without needing an adapter ?
Not sure how much I'd gain out of QC 4.0... but considering price, availability, and potential heat issues; I reckon this is the right choice for now.

AndroidAuthority articles are bull****. Don't trust those bias reviewers.

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.

Nope - Quick Charge 2.0 maybe, but not 3.0.

That's a QC 3.0 only powerbank according to it's specs.
Take your own conclusions from that...
It charges as fast as the original wall adapter

S10 devices only support 2.0. your previous post said it supports 3.0. it does not.
Any charger will charge the phone, but not faster than the specs allow. I can have a 25w charger but my S10 will not take the 25w capacity

Connect a QC 3.0 charger, see the charging speed, come to this thread again.
go check out the 2000$ Fold, it listed "compatible with qc 2.0".
2000$ phone supports qc 2.0
s10 support qc 3.0 HAHAHAHA
hope you get what i saying ..

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+

Lmao. I'm really hoping they release the 25w in next update. That would make the device perfect for me.

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.

Thank you!
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).
purchio said:
It also supports Qualcomm Quick Charge 3.0 as fast charging, just like the S8 and S9s.

I've even quoted my first comment.
Just read what I said: that QC 3.0 charges also give S10 the fastest charging speeds it can handle, NOT QC 3.0 WATTS/SPEED/WHATEVER.
Pretty simple to understand..
Lol retraction at its finest.

What did we learn here? Anyone?

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.
