Hi,
Selecting a charger for mobile devices seems to be confusing nowadays, atleast for me[emoji16].
Can help me how much power does the S7 edge needed for Fast Charging and non Fast charging? I understand that the original charger included in the box has 5V 2A or 9V 1.6A output. Am I right to say that when fast charging is off, it will use the 5V 2A and if it is on it will use the 9V 1.6A?
Reason for asking is, I am using the original charger at home and my old htc charger from M9+ in the office. But when I use the htc charger with 5V 1.5A output, charging suddenly stops at 50-60%. I observed that the htc charger gets hot than its normal but my phone doesn't get hot. I turned off fast charging when doing this. It seems that the htc charger cannot handle the s7 edge and stops at certain point when it gets hot.
Now, i'm checking which wall charger should i buy to use in the office as it seems i cannot use an ordinary charger on newer s7 edge device. Am I right to say that the minimum requirement for power output for s7 edge is 5V 2A? It doesn't matter to me if it is just non-fast charge as I normally on my desk all day so non fast charging is okay.
Please help. I need an advise for this.
I want to buy samsung fast wireless charger but it will work on my note 4 with qi receiver?
All samsung fast wireless chargers are backward compatible with standard qi receivers, so yes!
but will the fast wireless charging work too?
Thank
I don't think the Note 4 supports quick wireless charging. I know it does support wireless charging with the right wireless charging kit installed and Samsung's own wireless charging back cover.
I found that not support fast charge in qi enebled dervices (maybe with right kits too) so any way to get fast wireless charge?
Fast wireless charging won't work with the note 4.
Your question has already been answered. If you want fast charging, plug it in.
Nope. Since the Note 4 wasn't design with fast wireless charging capabilities. You will have to plug it into the mains via the included adaptive fast charger in order to charge it fast.
There have been some initial reports of a "wireless charging paused" problem when attempting to "fast" wireless charge with certain chargers. I have experienced this myself, researched it, did some testing, and have some thoughts I think would be helpful to share. The YT link illustrates the problem: youtu.be/IkR3H1Tnlp0
tl;dr The S8/+ only "fast" wireless charges with an OEM Samsung charger. Third-party and knockoff "fast" wireless chargers will experience the "paused" issue. They can work as standard wireless chargers but must be paired with a power adapter that forces it (non Samsung Adaptive Fast Charger and no QC 2.0+ power adapters, etc.) Previous generation Samsungs​, such as the S7/Edge and Note7 (R.I.P.), do not have this limitation.
The person in the YT video must have had a knockoff (one good indicator is the hard plastic "lip" on the stand should instead be a rubberized material). I have two knockoffs myself and my results are the same. I also have a third-party Choetech and both of the previous OEM versions; pad and stand. I do not have the new convertible stand.
The long version:
Before I start, please note that I make a clear distinction between a wireless charger and a power adapter. I refer to a wireless charger as the device which contains the inductive coils on which a smartphone rests upon for wireless charging. A power adapter is the device that plugs into a wall outlet and has a USB Type A port to supply the wireless charger with power via a USB cable (typically a USB Type A to micro USB cable). Basic stuff, I realize.
Initial reports from around the web, in particular the above YT video, pointed me in the right direction. According to my own testing and conclusions, the problem isn't the wireless charger or the power adapter but rather a seemingly intentional block placed by Samsung when attempting to use Samsung's "fast" wireless charging method on the new S8/+ with third-party or knockoff "fast" wireless chargers.
As you may know, the "fast" wireless charging method is a non-standard, proprietary Samsung technology, which is said to be compatible with standard Qi wireless charging. I have concluded that, apparently, the new S8/+ can now detect if a "fast" wireless charger is OEM or not. If it is not, you will experience the "paused" behavior when attempting to "fast" wireless charge an S8/+. However, standard wireless charging works fine on the few non-OEM "fast" wireless chargers I tested.
While you cannot select between the "fast" or standard wireless charging method by way of the wireless chargers themselves (or any that I've seen at least), you can force the wireless charging method based on the power adapter you pair the "fast" wireless charger with. Aha!
If you're like most who purchased a third-party "fast" wireless charger to use with a previous generation Samsung Galaxy, you may remember the fun of having to pair it up with the right kind of power adapter that would enable "fast" wireless charging, such as a QC 2.0+ power adapter. Using the "wrong" kind of power adapter should force a "fast" wireless charger to use standard wireless charging and then the S8/+ will no longer experience the "paused" problem. Obviously, this means the S8/+ will wirelessly charge at the standard rate.
I tested and was able to successfully "fast" wirelessly charge my S8+ with an OEM Samsung Fast Wireless Charging Pad (flat, lay down style) model EP-PN920, which is the first iteration of a "fast" wireless charger from Samsung. I was also able to successfully "fast" wirelessly charge with the next iteration wireless charger, the Samsung Fast Wireless Charging Stand (stand up style) model EP-PN930. Both were paired with a basic OEM Samsung Adaptive Fast Charger USB power adapter. I also tested the above wireless chargers paired with an AUKEY Quick Charge 2.0 Wall Charger power adapter model PA-U28 (5V/2.4A) and was able to successfully "fast" wireless charge my S8+ on the OEM Samsung wireless chargers.
I also tested a Choetech Fast Wireless Charger model T518. When paired with a power adapter that enables "fast" wireless charging, I experienced the "paused" behavior on my S8+. When paired with a power adapter that forced standard wireless charging, my S8+ was able to wirelessly charge at the standard rate without issue. This was the same result with two China knockoffs of the OEM stands (one good indicator is the hard plastic "lip" on the stand should instead be a rubberized material).
My reasoning behind this block being seemingly intentionally placed by Samsung seems pretty clear based on the above results. I think the "paused" behavior may not be intentional, however. It could also simply be a mishap with just a certain batch and Samsung may address the issue in the future. Here's to hoping, but don't hold your breath.
Suffice it to say, this is only my experience and yours might be different. Please do feel free to comment on your own experiences. I think it can be helpful to get additional perspective on the topic. Thank you.
My two chargers have the exact same Serialnumber like yours.
I have the prbolem with one of them. But this one had the problem also sometimes with the S7.
I bought them online for about 13 Euro each.
I am betting samsung is so paranoid about battery splosions they have decided to not allow fast wireless on chargers with no fans built in. Since they are the only ones with fans, they block everyone else.

Not EVERY charger without a fan is blocked...
I just bought an Anker fast charging plate and am pleased to say it works fine with fast charging. I already had two Samsung Fast Charge units which worked with my S7 but refused to go into fast charge mode with the S8. I also tried an Aukey model (with fan) which worked for 30 seconds then stopped. The Anker plate is low-profile, has no fan and LED lights which turn off after a few seconds once fast charging has started. The Anker was from Amazon and can be found here.
Which Aukey Charger with fan was that do you have a link?
This one. and it doesn't work. The Anker is fine.
I am having just hte opposite problem. My Samsung branded fast wireless charger with the Samsung Adaptive Fast charger that came with a previous phone (S7 Edge) has this issue, but no-name fast chargers with other brand QC2 power supplies work correctly. I can get normal speed charging on the Samsung with a generic 2amp power supply. I don't think mine is a counterfeit charger. If it is, it is very very good copy.

Now that I think about it..... It also surprisingly didn't work on my S7 Edge if I had it in a case except for one very slim case, where my old Nokia charging pad and a no-name fast charger did work. I bet I did get snookered. It was from one of those daily flash sale sites (Yugster) and the price was surprisingly low....
What have you paid? Which charger model and what are the last digits of your serial number?

How long have you had it? I have that exact same charger and it no longer fast-charges (or charges at all). It now charges for about 10-15 seconds, then the light starts blinking white and it stops charging altogether! It's infuriating.
Edit: but it DID fast-charge properly for the first 4 days or so.
The Aukey one just blinked white after successfully charging for 20 seconds or so. It was useless. I now have a couple of Anker fast charging mats and they both work fine.
I returned the Choetech since I was getting the charging paused problem. Went with the Pleson and it seems to work great with my S8+.

Wish it were USB C though.
There seems to be only (1) USB C fast wireless charger on Amazon and it is $10 more expensive than the Pleson. Not worth it for me.

Why? Does it matter how a wireless charging plate connects to its charger? Once connected that's it - and they come with a cable.

Maybe if he wants to charge his phone faster he can unplug the cable from the wireless charger and plug it directly into the phone - but that would need a USB-C connector on the wireless charger...

I know it doesn't matter.. but USB C is more convenient for the times I will move my charging plate. Also, if need be, I can quickly unplug the USB C cable from the plate and plug it directly into the phone if I want quicker charging.

It's like you read my mind.. LOL... (it's actually just common sense I guess).

Ah, OK, that makes sense!
I have the same issue. I had 6 Fast Wireless Chargers from various brands that I used with my S7 Edge and all worked great. Now that I have the S8+ only one of them works. Why that one - I have no idea. But the other 5 do not work regardless of charging adapter or cord I use.
The standard (non-fast) wireless chargers seem to work fine as mentioned as well as using these fast wireless chargers in "non-fast" mode by using a non-QC adapter. It's very frustrating to invest in tech and expect to be able to continue to use it. I had a fast wireless charger in the cup holder in my car so I could just drop my phone in there and it would fall against it and start fast wireless charging, but it is one of the 5 that do not work with my new phone.
Posted this in the S7 forum too but posting here as it relates to the S8 charger. The answer here probably isn't complicated, but the question is, hopefully I'll explain it right:
I've just bought an S7 Edge. My current wireless charger is the OEM samsung pad type for the S6 so pretty slow. Therefore I'm going to upgrade to either the OEM S7 fast wireless charger stand, or the OEM S8 fast wireless charger stand. The S7 one is cheaper and charges just as fast, however the S8 one has a USB-C connection, which could swing it for me depending on the answer to the following question:
Can I use the USB-C charger from my Acer R13 Chromebook and just plug it into the S8 pad/stand? Assuming I can will it fast charge (well, as fast as wireless can) or will only the adaptive OEM plug do that?
Thanks in advance
No

Thanks. What's the reason? And will the R13 charger work regardless of capability to fast charge?
Using 'Ampere' to measure charging current, worked well on my old S4 and showed the huge difference in cables and chargers.
Now with my S7 Edge I'm seeing lower charge currents (max 1000ma compared to 1400ma with the S4). The Samsung 'fast' adaptive charger makes no difference !?.
Loving my new Samsung inductive 'fast' charging pad (around 75% of the cable current as expected) yet if connected to a samsung 'fast' charger the lights on the base just flash ?.
Anyone had experience ?. The model numbers from the supplied charger and cable (new S7 Edge's) would be VERY interesting.
Thanks in advance...
Fast charging only works with the screen OFF
