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.
2) Does the "Car wireless charger" sold by samsung charge slowly compared to "wired charging"??

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.

The Galaxy S6 doesn't have a qualcomm processor so it shouldn't make a difference right??
Doesn't Samsung use a proprietary solution when it comes to fast charging???

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.

Hi,
Getting an EU version of the Note, so I need to buy a Uk charger, is the charger for the Note and Galaxy S2 compatible? Thinking buying a 3rd party Galaxy S2 charger on ebay.
Many thanks
I suspect any 5v microusb charger delivering over 0.5A will be fine.
Expansys sent me a standard HTC one (5v 1A) with my german note and I am in the UK.
Thanks, I have a couple of generic USB wall chargers at home, so might as will use them with the Note.
I can't answer the question directly, but that big screen, fast processor and larger battery are going to take a bit more juice than your average phone, including the S2. When it comes to mains chargers that may not be a big deal, unless you leave the phone active while charging, but might become an important consideration if trying to use the phone for satnav in the car, for example.
At the moment I'm using an Orange San Francisco. That has a 3.5" OLED screen and a 600MHz single core processor, so hardly an energy guzzler. The supplied charger is rated at .7A. In the car, when using satnav, my generic USB car charger cannot quite keep pace with the energy demands of that little phone and the battery level actually drops slowly while connected to power in the car. I'm definitely going to be looking for something more robust for the Note.
Note charger is 1 amp, Nexus S .7 amp, Note charges fine off the .7 amp charger.
I assume a standard Samsung GS charger would do, the output on it is 0.7A?

You not only need a charger that can deliver more oomph, but also a lead or charger, possibly modified, that will allow the phone to draw that current. I have 1A USB chargers for the car but a regular data/charging lead only permits the phone to charge at the standard USB maximum current of 0.5A. I had to open up one of my chargers and solder the two centre pins together. Shorting those two pins signals to the phone that it can draw the full "mains" current rather than the 0.5A USB maximum.
I haven't yet charged the Note in the car, but on my previous phone the charging status would show "Charging (USB)" prior to the mod and once modded it would show "charging (AC)", which is what you need to keep the phone charged and charging while in use rather than slowly depleting.

I can confirm that SGS2 charger works on note. However charging is slow ( its 0.7 A )
However the note charger ( 1.0 A) charges faster
dont have a 2 A charger to test but I would say that it would be the same speed as 1 A charger.
If we want faster charging, we will need the kernel to modified.
The downside would be shorter battery life.

Thing is would the USB cable that comes with the note (designed for computers) be suitable in carrying 1000mAh?
I heard that USB cables that come with phones are 0.5mAh so it won't make use of the 1000mAh...
Can anyone confirm this? If so then it's better to buy an out and out 1000mAh plus wall charger or a worldwide travel adapter.

yes it will work fine, because the charger accepts 100-220vac 50/60Hz
The Samsung power adaptor that comes with the Note is a Universal one (110 Volts - 240 Volts) and is rated at 5 Volts 1 Amp output.
If you need an alternative for some reason (or a spare).........
Personally, I am using a generic iPad mains adaptor with dual USB sockets. The device was made in China and has a total current output of up to 2 Amps. It is a also a worldwide model. I think it charges faster than the Samsung charger.
It also charges the Note when using the MHL>HDMI output. I have read some postings that the Note very slowly loses charge when the MHL>HDMI adaptor (which has to be externally powered) is in use. With this 2A adaptor, it continues to charge.
You could also try the Genuine iPad adaptor that also works worldwide and delivers a genuine 1 Amp rather than some of the cheapie models that struggle to supply that current.
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.

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.

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
WHat is a good wireless charger for the Edge phone? I prefer not to alway connect with the cable......
Choetech has a few fast wireless chargers listed on Amazon.
1: Single Coil - Pad-type
2: Single Coil - Circle-type with Smart Lighting
3: 3 Coils - Pad-type with Smart Lighting
I was researching this yesterday. What you have to remember about wireless pads is that typically a 2.0 pad will charge similar to a Non fast Charge 2 plugin-in charger. So like a standard charger. Once 3.0 ones are out I assume it will be a similar scenario. Hopefully some day down the line they will be just as fast as their plugin counterparts.
As far as those links above, 10w max isn't very strong considering a plugin 3.0 is about 18w and even a 2.0 is 15w. So 10 watt seems pretty dinky for a wireless still. Still I guess better than the old 5 watt ones.
Tronsmart is making a fast charging capable qi charger which should be nice. I used to have a TYLT VU (angled qi charger) for my Nexus 6 that as great. I would buy an angled one because it's easier to see your phone on and impossible to not have it charge.

After some more digging I found this: Nekteck Wireless Charging Pad (18w QC 2.0 Adaptive)
Looks very promising; 18w, slightly tilted instead of laying down flat, smart lighting.

It does look nice, but it is just the pad, correct, you still need to use your own samsung charger?

Correct. You can also buy a "QC 2.0 Adaptive Fast Charger" like this.
please use the Samsung original or certified third-party 18W QC 2.0 adapter as its power source.
Already got one on order so maybe will get this too. Keep in mind that still this will NOT charge as fast as a 3.0 18w direct plug. Not sure why that ends up being the case, but that is what I have read.
BUT::: Lower down on the order page it say:
"Fast Charge Model(10W Output Max) ONLY "
So does that mean if you have an 18w source it still only delivers 10w to the phone? Seems hardly worth it. I sent them an inquiry about this. (it's not listed on their website)

I received that charger 3 days ago.
I can not test it on the S7 just yet of course, however I have tested it on other phones and it does charge faster than a standard Qi wireless charger does.
I will post up some information about this charger, and the Cheotech 10w circle fast charger that I have also, as soon as the phones arrive.

if you could do a compare with the plug-in 2.0 charger, that would be great.
Hi guys, I'm new to wireless charging, and I'm a bit confused as to which wireless fast charger I should buy for the S7...is there anything different about the wireless charging on the S7 than the S6, Note 5, etc.? Are there new chargers coming out soon that are somehow better than the ones currently on the market? I'm just wondering which charging pads would give me the fastest charge. If anyone could shed some light on this for me, that'd be helpful
Here is what i got for our Note 5's, my wife and I both have one. They have worked great so far. You need to use your Samsung fast charging adapter with it. For $19.99 I could not be happier.

These so called fast charge wireless models are all over the place with specs. I'd wait for the newer crop to be out and tested.
My Choetech fast wireless charging pad still works great so far. I will recommend Cho

My Choetech fast wireless charging pad still works great so far. I will recommend Choetech. Very stable and warm slightly. They have many kinds of wireless chargers, which has lots of good feedbacks on Amazon. :good:
Well now that there is a report that the s7 and s7e do not support quick charge 3.0 (sad) I'm not sure what's what.
I have this one: www.amazon.com/Wireless-Charging-Pad-CHOE-Qi-Enabled-Adaptive/dp/B016DAFUGY
Works REALLY well for me, charges a lot faster than the old Nokia DT-900 pads I have scattered around the house. Choetech is sending me their newest model to test, so I'll have a writeup for it here soon. Maybe a week or so?

That looks like a good one. I have a pad already, If I use one of the new power supplies will the charge fast, or need to upgrade the pad????
You'll need to use a Quickcharge 2.0 plug, to have it fast charge. It's not going to go any faster if you use a QC 3.0 unit though.
This is what I have now
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.
Hi guys,
I've noticed Samsung S21 ultra supports 15w wireless charging - I was just wondering if all 15w wireless chargers were compatible? Or whether they specifically have to support "Samsung fast charge 2.0" - like the official chargers?
Wondering what others have bought? Let me know! Thanks!
I've been doing some research, I know that Samsung devices are supported by QC 3.0... but just wondered if this is true for wireless charging? Will generic 15w wireless chargers work? Would be much cheaper!
While generic 15w chargers will work, there are other factors that needs to be considered. Such as what kind of brick you are using with the charger and things like how thick the case you are using.
Sammy only have one 15w charger and that is OG stand. The other sammy fast wireless charger is 9w (input still requires 15w though)
Can't comment whether which 15w is reliable or not as they are 3rd party and varies from company to company.
A fair point. I guess if you use a QC 3.0 brick with at least 15w output - with a 15w wireless charging pad it should theoretically work then?
Be interesting to see which ones people find works for them!

Probably works but wireless charging is inefficient and needlessly raises the battery temp which is detrimental to its longevity in the long run.

An 8 W Samsung wireless charger does not heat up the S21 ultra more than the 15 W charger I have (this cames with my Note 9). I would think a 25 Watt charger would heat it up more. The reason I bought the wireless charger was for my Note 9 and now the S21 ultra is that my Note 9, despite considerable babying, is showing some issues with the socket (it often will show cable charging instead of fast charging and despite changing cables, cleaning out the socket with compressed air and a toothbrush etc). So yes, in general you are correct but socket wear must not be discounted.

I hear what you're saying about the port. I do a lot of partial midrange charges so 3-4 times a day isn't uncommon.
The biggest thing is not to hit/drop it when a cable is connected.
Battery or port assembly the phone needs to come apart...
I have a couple of these wireless chargers. Mine are an older version that don't have a USB plug at the charging pad (mine has a non-removable wire from the pad). I can't seem to find specs on their site now, but when I bought mine they claimed they were 15w. I only bought them for how they look. I personally don't care how fast they charge, I prefer slow charging for better battey life, I'll use wired chaging when I need something faster. I have fast wireless charging disabled on my phone. But I just checked it, if I enable it, it does say "fast wieless charging" on the sceen when I place it on the pad, and the time to full charge is a little quicker than with fast wireless charging disabled. Still not as fast as wired though.

So the best way to check this is to download Ampere!
Grab it from Google play store, install it, and then open it while you are charging the phone on different wireless pads.
You work out the Watts by using;
Amps x Voltage
Let me know how it goes!
