Late week i got my Samsung fast wireless charger pad
At first my device doesn't recognize fast wireless charging and not even show the toggle switch for turning on fast wireless charging..
It is simply says wirelessly charging but instead of charging..my note 8 drains battery...
I have the same issue. I wonder if our wireless chargers are to blame? I got mine from the Samsung/note 8 promotion.
Try a different USB cable. And what charger are you using?
what make and model is the pad? also if im not mistaken, fast wireless charging needs at least 10 watt/5v 2amp capable chargers.
also check for crappy usb cable, use an other one.
I in the past have found that most def the charge blocks and cables make all the difference in the world with the wireless charge.....
I will second these post
My Note 8 used to charge successfully on the Samsung Fast Charge Wireless station, but now it says it's fast-charging but it actually continues to drain. I have three chargers in the house, using the provided Samsung USB cable, and they continue to charge my Samsung S8 and S7, but the Note 8 does not charge successfully on any of them anymore.

Will plugging the Note into my PC via USB cable also charge Note like my iP did?
Yes it does also charge the NOTE
It will, but remember that charging USB had a slower charge rate, and also depending what your doing with your phone while charging, it might actually not recognize its charging, because the output is greater than the incoming charge and your battery level will drop.
you can't rain on my parade, I'm on the road to my fairytale!!!
It will charge fine but at the slower USB trickle rate, like most devices.

Since I got my note 3 I've been charging it with my old AC chargers I bought on ebay which is a generic micro-usb charger (I got a couple of them laying around the appartment). I use my old chargers often because the samsung USB cable which was provided with the phone is always pluged into my desktop computer, and I didn't want to go trough the hassle of moving the cable all around the house to charge my phone.
Well anyway, so far I've notice charging times were pretty long(6-8hours), but I shrugged it off because I simply thought a bigger battery require longer to charge. But this weekend I slept off at my in-laws and I brought my samsung cable and AC adapter. I looked up with better battery stats and notice the charge time was around 3times as fast. (2hours or so for a 100% charge). Dammmn!
So why am I getting long charges with my ebay chargers?
Is it because they are cheap china product?
Is it because they don't have the USB3.0 port?
I'm thinking the USB3.0 has nothing to do with charging times if it's pluged with an AC adapter right? So my long charge time must be because of cheap products? Ok then, but if I want to buy additional chargers, or even a cradle for my bedside table. How can I know if they will have the best charge time? Am I forced to buy samsung branded stuff just to make sure?
Cause I'd be interested in something like this :

but I'm not gonna buy it if it takes double/triple charging time..

The Note 3 should charge in just over two hours with either USB 2 or 3 cables. If you download https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free&hl=en that will tell you the charging current. It should be 1200mA with the screen on and 1800mA with it off (trick is turn the screen off for 10s then back on and refresh and you should see 1800mA).
As long as the charger can deliver 1800mA and you are using a decent quality cable that should be all you need. Plugged into a USB port you'll only see 450mA on either USB 2 or 3.
Usually the ones that charge this quickly have an output of 2 amps. That is the output of the charger that came with the phone.

wow thanks there lots of useful stuff
I've just upgraded my unrooted LG G Pro 2(D838) to lollipop. Charging through my car usb adapter is now very slow since I updated. I have tried two chargers, both of which were charging at the full rate before, one of which is a genuine samsung charger - they both have over 2A output. The phone does recognise the charger as an AC charging source, but currently isn't charging above about 200mA.
I am using a Samsung AC charger at home which works as normal. I've had a bit of a look online and people are experiencing the same issue with the LG and other lollipop devices. One of the suggestions was to short the data pins on the usb cable, which I have done but this doesn't seem to have fixed the issue. If the phone is off it charges at the faster rate.
What I can't work out is why the charging speed is different between the samsung AC adapter and the car charger, when it detects both as an AC source? Is there some communication between the two, or are there any car chargers that will provide high speed charging that will work?
any suggestions are appreciated!
I went cheap and tried to buy a charger off of wish.com and I believe it was total junk. Even at its best though, it quoted a wireless fast charge at 1 hour and 54 minutes vs 1:17 corded when (battery was near dead).
I got a refund for that junk charge charger but I'm not interested in a OEM Samsung charger if works the same. I thought the wireless fast charge worked at the same rate.
Here's a link to the specs of that charger...connected to the normal samsung charger at the wall outlet.

No it doesn't, 2 hours is the best you'll get with a wireless charger.

Then what's the difference between the original wireless charger that samsung sold and the available "fast" wireless charger?

Ther is nearly no difference.. I have the same charger you had. But I have 2! of them with same serial number as yours
Wireless Fast Charging works with about 10 Watt from wireless charger to the phone.
while wired charging (Quick Charge 2.0) works with about 15 Watts.
Bevore Fast Wireless charging - wireless charging was only 5 Watts (Charger to phone)
Was planning on using the fast charger that came with my S6 Active to keep at work. It still fast charges my S6 but when I use it with my S9 it only slow charges. I've checked the markings on the charger and they are exactly the same as on the charger that came with my S9 even down to the model number except for 1 thing. One says made in China and the other says made in Vietnam.
The fact that the old one still fast charges my S6 to me rules out the charger being faulty. Has anyone else experienced anything like this?
Ive been experiencing the same problem with my Mi power bank 2i.
When i connect it to S9 plus ots gives Fast charging message and then turns to cable charging.
I hope they rectify it in a patch.
This is ridiculously bad as i travel a lot and only depend on power babk 2i as it fast charges all samsung phones.
Any1 else having same problem ?
The charger that came with my S7 fast charges the S9+ without any issue, as does the 3rd party car charger I'm using. Does the one that came with you S9 fast charge properly? Are you using the cable that came with your S9 with the old charger?
I have a ton of chargers. The one that came with my nexus 6, my ATT prime time tablet, and my LG v20 and LG v495 tablet all fast charge my 9+. They are all Qualcomm fast charge 2/3. My Anker qc3 does fast charging as well. Variety of cables, some generic, some LG.
If I think of it when I get home I'll check my power bank. It's a qc 3.0 and is a 10k mah I think. Was 20ish dollars on Amazon.

Yep, the charger that came with my S9+ works perfectly, and yes I am using the cable that came with my S9+
I have the same issue with an ANKER charger and CHOETECH cable that was working perfectly with my S8+...
i charged the my s9+ after draining it completely without powering it ON.
Charged in 100mins.
The progress was like 15 mins -24%,45 mins - 60%, 80 mins - 90%, this is the first time i was able to charge it quickly.
I was very disappointed with charging time but this is third cycle, so i am sure its learning the way we use.
I charged it with QC3.0 charger
I will be posting more about this.
I think I have a Fast Charge problem with my AT&T branded S9+. Fast charging displays when I use the included cable and wall adapter and even if I use the included wall adapter and any of These Aukey Cables. But if I use those cables or even the cable included with the phone with This Aukey QC 3.0 Car Charger or This Anker QC 3.0 Power Bank I cannot get Fast Charging to display. Yes Fast Charging is enabled in Battery --> advanced. It worked for the first couple days with all combinations but now its as described. Even did a factory reset last night and restored from my previous phone's Google Backup which I did not do the first time (used Smart Switch the initial startup on launch day and only moved a few things over) Should I swap the phone out for another?
Im getting the same issue when using Aukey power bank. It does not fast charge my S9+. Works perfectly on S7 and S8. Do you guys have any luck?
Any resolutions for this? Same is happening to me. Is there a particular brand of cable that might help?

Most of my cables are Choetech brand from Amazon. Every single QC 2.0 charger fast charges my s9+
Just throwing this out there to rule it out, you can enable/disable wireless charging in the Advanced Features, Accessories section, check it's on.
Same here? Is this a bug introduced by a firmware update? Why aren't enough ppl talking about it
