I had a previous model of this unit which was at the old "slow" charge rate and was so pleased to get the new and improved version. They even fixed the few issues I had with the older version. This model has the charging cable in back instead of sticking out the side, the LED indication light is much dimmer, although larger, which makes it easy to see where to place the phone in a dark room and not act like a flashlight while trying to sleep.
The display angle is acceptable, it works well through a case, although I haven't tried a Defender case yet and the fit is more secure than even the Samsung charger..
The unit uses a microUSB connector and a 2.1A adapter, not included.

To anyone thinking of wireless charging for our device - I advise against it. Not only will it charge rally slowly compared to the standard charger - it'll generate a tonne of heat and kill your battery rather quick.
I use a cheap chinese QI pad and it doesn't get hot but I discovered you need to switch off fast charge (under battery) and it works fine. Granted it charges at a rate of 20% in 30 mins but for overnight it fine....mine doesn't seem to get hot or even warm.

I have used wireless charging since the Nexus 4 and never had any trouble with reduced battery life. Nexus 4, Galaxy S4, Note 3, Note 4, and Note 5. Except for the S4 which I returned to switch to a Note 3, the battery life is about 20 to 24 months with little or no reduction in usability. When I get a new phone I hand the old one down to my wife and other family members, and I have ordered the new batteries when needed.
This is definately a firmware bug that it only fast charges whilst the screen is off. Saw this in the early days with my note 5 and an update fixed it.
Funny though with the Samsung wireless fast charger i just received and my old Nokia DT900 wireless charger the only difference in time is 5 mins... so much for fast charging.
Hi,
I have a funny setup: solar charger/table decoration connected to a wireless charger (stuff from ebay with Samsung logo).
So I assume it will charge so slow if any at all. But still.. at least won't discharge during office hours.
Would this hurt battery in any way?
Well it should not hurt it. If most, like all wireless chargers they are actually good for your battery health. Wireless charging charges slow but does not strain the battery as much. If you fast charge your phone it does worse to the battery long term
However if you post the model of your charger we can look it up and be sure
will slow wireless charging hurt my batter if I'm using a Samsung wireless charger?
model: EP-PG950 - 2018 model that i received with my note 8
Same Question
I had the same questions. I also see there is an option for fast wireless charging in settings. If slow charging is better for battery health and you mostly leave your phone charging over night, would it be best to leave fast charging off so it takes most of the time you are sleeping to charge slowly until full?
At the moment I leave my phone at low charge while I sleep and wake up 2 or 3 hours earlier to plug it in so that I don't over charge the battery.
Wireless charging creates more heat so this question is hard to answer as I have not seen any good breakdowns of qi vs fast. I have been wirelessly charging from older chargers like the wireless charger that came out for note 4 and some 3 coil charger from Nokia that was on clearance for $15. They're not fast wireless charging and phone does get warm. I also charge off of 500ma and 1A chargers usually and only use the adaptive fast charging (QC2.0) when I need a quick top up. Heat doesn't help your battery.
Perhaps somebody can do a comparison with regular qi, fast qi, 1A or less charger and the adaptive fast charger and see what the min and Max of battery temp is through out charging cycle. I'm guessing 1A charger is the best and regular qi is ok. Fast wireless and Fast charging get your battery temp higher.
Hi guys, my Note 9 charges extremely slowly when it is on a the fast wireless charger. It does say "Fast wireless charging" but it takes over 4 hours to charge fully. My mum has a Note 9 as well and her phone charges significantly quicker than mine on the same charger. I have tried turning off and on the fast wireless charging option and factory resetting my phone. Has anyone of you experienced this same problem?
Both phones are the same model, Exynos 128GB
I have tried multiple wall adapters and wireless chargers as well. The official samsung wireless charger convertible and a remax fast wireless charger. Tried with Samsung adapter and QC3.0 adapter.
There was an instance where my wireless charger was fast charging it and the charger burned up. It got really really hot to the touch and that particular charger stopped working. I'm thinking that it might have damaged the charging coils?
It might be a hardware defect, is there a way to back up my phone fully? Like an iPhone? Or is smart switch the best option I have right now without rooting?

was it always this way?(even b4 the charger burn)
is cable fast charge also slow?
I think it was faster before that incident. But I am not so sure.
Is there a software thing that might have done this? If not I am almost certain it is my phone
Fast cable charging works flawlessly.

go to accessories and disable fast wireless charging and compare. then next time around reenable it and see if there is any difference.
Do you use any protective case? Maybe it contains metal that blocks the magnetic field of the charger.

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!
