Fast Wireless Charging Backwards Compatibility - Galaxy Note5 Q&A, Help & Troubleshooting

Everything I've read about fast Wireless Charging compatibility was that it was backwards compatible with the plates we have now. But now Samsung is saying we need to buy their $70 option for that. I'm wondering if this is just a money grab of if I could plug a fast charger into my nexus wireless charging pad and get it to fast charge. Has anyone else even wondered this as they've read about this new standard with "backwards compatibility?"

I don't think it works that way. The regular Samsung wireless charger comes with one of there adaptive fast charging bricks and it does not have fast wireless charging.

Fast Charging will only work with the Wireless Fast Charger. I have the note 5 now and have tested it with 10 different chargers and it works but not rapid charging.

Yea, fast wireless charging is new. It's unfortunate the charger is so expensive, but this is new. They'll be some aftermarket fast chargers soon

USB Fast Charger

Seeing as the M8 supports fast charging, but the charger in the box is the standard 5v/1amp charger, would anyone know if the new Google charger would work for fast charge?
https://play.google.com/store/devices/details/Nexus_Charging_Accessory?id=nexus_charging_accessory
It's 9w/1.8amp output. I have one and was thinking of getting an M8 so it's something I could keep to use if I do get one
(If this should be in Q&A please move it, but thought it might be handy for anyone looking for a fast charger from a reputable brand should it work)

My M8 was getting very warm using this charger, is yours?
Not that I have noticed but I'll keep an eye out when I get mine back. It does charge everything I own quick as hell though.
They're supposed to be releasing a quick charge 2.0 compatible charger for our device soon that's supposedly is pretty good. I find my phone charges much faster than my DNA as that thing had a slow charge mode that was brutal.
I have a few red band charge only cables that charge the phone fairly quickly.
The charger that came with my htc M8 says 1.5A on the back of it. It charges the phone pretty fast compared to others I have used. I did try to use my samsung charger that is 2.0A but I noticed the phone got warm. Definitely not hot to the touch but enough for me to not really want to ust again and stick to the stock charger.
The charger that came in my box was 1.5A.

The stock HTC charger is 1.5 amps, or at least the ones in the UK are.
While the phone can take 2 amp charge, by doing so you will heat the battery up much more on each charge, and this extra heat will reduce the charge cycles of the battery(life of the battery), not really the best thing to do on a phone that can't have it's battery replaced.
I've got a 2 amp charger for the car, as when I use that I tend to need power fast, but I have my phone mount on my aircon vent so the phone is kept very cool even if using google maps while fast charging at 2 amps.
How do you tell if a charger has Quick Charge or not?
Apparently the one that comes in the box with the HTC One M8 has Quick Charger 1.0 but I'm looking at the charger now and there is nothing on there to say that it has this feature
I would like to buy another one as a spare to put in a different location to charge without having to take my charger with it but I don't know how to tell if it has it or not before buying it without getting it and actually plugging it in and using it
M8 has quickcharge 2.0 but no 2.0 compliant chargers have been released, the stock charger uses quickcharge 1 technology, HTC is panning to release a qc 2.0 compiant charger later this year.

What do you mean by Samsung 3.0 :S
You're not talking about USB 3.0 are you?
Then yes the Samsung Galaxy S5 does have USB 3.0
USB 3.0 is just a faster way to transfer data and as far as I'm aware the charging speeds are still the same standard speed
You do need to have a USB 3.0 cable and a supporting device (USB 3.0 port) to utilise it the faster transfer speed
BUT in saying that the Galaxy S5 does have the same chip as the HTC One M8 as far as I'm aware so I would imagine it would have the Quick Charge 2.0 function as well but whether or not the phone has it enabled or comes with a Quick Charger I'm not sure
-EDIT
Just did some research
Turns out USB 3.0 standard port has a current of 900mA while USB 2.0 is 500mA so the power current on a USB 3.0 has also increased

The Galaxy S5 also has a different charging cable, but can still be used with standard micro usb as well. I was amazed at how fast my gf's phone charged with the stock S5 cable and wall charger.

Not the one with the s5 but any of their earlier cables would fit our M8's.
Hey guys, for the ones that asked I have got the Google nexus fast charger and it is not fantastic. Takes 1,5 hour to charge from 5 to 100%.
I was quite desapointed. This is incredible I can't find any quick charge 2.0 charger anywhere, did someone do ?
The compatible charger must have a qualcomm quick charge logo, they said.

[Q] Fastest Car charger.

Hi i am currently using the basic motorola charger and it feels like tis really slow. I know that the note 2 can handle 2amp chargers or more. Can anyone reccomend a fast car charger and if neccesary a fast charge cable to use in the car. I have a toyota which only charges while the car is on so the faster it charges the better. Thanks for your help

Sent from my GT-N7100 using XDA Premium 4 mobile app
If only "pretty quick" and "pretty good speed" were reliable metrics to go by.
I've yet to find a car charger that will get more than 1.1amps on the meter. Max is 1.8.
1.1amps is enough to charge the phone "pretty quick" normally, but not if it is loaded down. Once I get GPS, bluetooth audio and Torque Pro going at the same time, I find that 1.1amps will actually result in a slow drain. I use an inverter and a stock wall charger which keeps the phone charging even at full use. I've yet to find a aftermarket car charger that will do the job.

question about new wireless charger

i got the new (circular) wireless charging station from samsung as well with s6e. i was wondering if i can use the advance fast charging that comes with the phone on the wireless charger to have it charge my phone wireless faster.
or will it damage the charger?

I don't think wireless charging will be any faster no matter what 5v USB adaptor you use as the wireless pad will only put out a set current, but I used the adaptive fast charger that came with the phone and to give you a rough idea of it's speed it topped my Edge up from 24% to 97% in about 2 hours. Quick enough for me and way faster than my old Nexus 4 on wireless charging.
While we are on this subject, would it be harmful for the phone to be wirelessly charging and plugged charging simultaneously? Would it do nothing, charge even faster, or overheat and damage the phone? I dont plan on trying it, just curious.

I would imagine that once something is plugged into the USB port (charger, OTG or whatever) wireless charging would be disabled as a safety precaution. This has been the case on other devices and I assume the same would apply in this instance.
The new wireless charger from Samsung supports AFC (adaptive fast charging) and it works with the cable and power brick that came with it. Been confirmed online a few times and I can also confirm because it charged my phone from about 5% to 100% in under 2.5 hours. That being said it's still not as fast as just plugging into the wall.

Just so everyone knows how it works you can use either the charger that comes with the phone or in the box with the wireless charger. As far as it charging faster the way it works is 50% in 30 mins when connected physically to the wall. On the wireless charging pad it goes up 20% in 30 mins. Now the good thing about it is when the devices charging port goes out you can still charge your phone and it's faster then the old pad they used to use.

This makes little sense. If it supports fast charging, it supports fast charging. If it's "not as fast as just plugging into the wall," then it doesn't support fast charging.
Fast charging will get you from 5% to full in around an hour, not 2.5; which correlates with where wireless tech is right now. Because regardless of whether or not it can support the power input from a fast charging adapter, wireless chargers currently cannot utilize "fast charge" tech. The fastest wireless Qi chargers currently are 5V/1A chargers. That's as good as it gets right now and they're nowhere near fast charge spec.
So regardless of what you may have seen "confirmed" online, the Samsung charger isn't a fast charge device.

The charging pad for me is a convenience factor. The fact that the fast charging gets ours phones up to 100% in 1-2hours depending on who you listen too is already fantastic. I like the idea of just walking in my door at home and placing it on the pad. Who cares if it takes a little longer that plugged in fast charging. Enjoy the ability of just placing the phone on the pad when you get home and have things to get done right away. Can't believe so much negativity for a phone just released with no development yet such as custom ROMs and kernels to make a beast of a phone, a KILLER beast. Sorry, just too much negativity for me. I have owned every Samsung Galaxy all the way up to this Edge 128GB. Yeah, you can't remove the battery. Yeah, no SD card slot. But the Internal memory is so damn fast, I am no longer in that complaint department camp. As for people moaning that their rear glass magically broke all by itself...I have a hard time believing that. I bought a Spigen NeoHybrid case that covers the back with a nice rubberized well fitting cover. The edges of the case ar metal, so you still have that wonderful tactile feeling of a solid metal phone. Best Samsung phone to date, IMHO and once ROMs and custom recoveries come along, it can only get sweeter. In the meantime, I will get off my soapbox and enjoy a phone that far exceeds my S5 and happily wait for developers to do their magic. Patience is a virtue. Sorry for my rant if it offends those that expect perfection out of the box. Yes, it's a damn expensive phone. So are IPhones. And they had issues right out of the box and their OTA fixes caused worse problems. I rest my case.
EDIT: The help so far from users here in general have been fantastic and my hat off to thos that helped me deal with softbricking my phone from either initially using a root file that didn't work for our 925 models, to showing the way to use Kies to actually restore the full stock image, and to ZiDroid to actually give us the ability to at least have a working stock recovery screen instead of the dreaded black only screen after rooting. And I enjoy using apps that require rooting so as far as warranty issues goes, I don't really care. If I can Odin, Kies, smartswitch or whatever new stuff comes along, then I'm a happy camper. Other here just need to do a little reading and search before posting rants that have fixes already out there posted. Off soapbox again
S6 wireless chargin box doesn't include cable and plug in it. I will buy a new data cable and plug for it. Should I buy adaptive fast charging cable and plug which comes with S6 or can I use S5/Note 3 charger for it? I am asking cos S6's adaptive fast charging cable and plug is more expensive than S5 charger

In Turkey, they give it free with S6 edge as a promotion without cable and plug. What kind of cable and plug does it have? Same as S6 fast charger or classic S5/Note 3 charger?

That's probably why you just got the pad since it was a promotion. I bought both of mine through samsung mobile website and they came with white ones but not adaptive fast charging. The pad cannot charge fast with it anyways.

Sent from my HTC One M9 using XDA Free mobile app
HTC device do not have a quick charge notification like a few others. You just have to make sure that the charger you got is Quick Charge 2.0 certified and you should be good to go. There are quite a few quick charge 2.0 charging accessories out there now. My favorite is the Aukey car charger which charges my phone about 5 times faster than the old car charger that I've owned for five years. Makes a huge difference, especially when you have only 15-20 minutes in the car.

Wireless Chargers

I'm going to be picking up the s7e in the next week and was wondering if anyone can recommend wireless chargers they currently use or have used in the past. All other Qi chargers are so much cheaper than the Samsung branded counterparts.
Also is there a big enough difference between the wireless fast charger from Samsung and any other Qi wireless charger that makes it worth buying?

Well th normal Samsung charger is free in the Samsung Pay promo (I don't think it applies to the UK), but it will charge slowly compared to a fast wireless one. I will have mine soon to test out I reviewed the Choetech 10W fast wireless charger below and graphed the charging speed compared to the stock quick charger. Samsungs fast wireless charger is only 10W from all accounts not 15W the phone supports. 10W wireless charging is still fast (see my link below), but any qi charger will work. I wouldn't bother with 1st party ones unless you get a good deal on one since wireless chargers from 3rd parties are just as good or sometimes better.
