So I found this article http://www.cio.com/article/3035071/...dge-support-15w-qi-wireless-charging-but.html
It seems like Samsung's new charger is not 15W standard?
I also found this product that shows a 15W standard wireless charger. I barely find any information about 15W Qi charger, such as the heat, charging efficiency etc. http://www.incipio.com/ces2016/ces-power/ghost-15w-qi-fast-wireless-charging-pad.html
3 times faster sounds very attempting.
Does anyone has any information related to the 15W wireless charger, does it heat up the device even more?
That incipio charger can't come out fast enough. By 2nd Qtr I'll be used to my Samsung wireless charging.
Just remember that the higher the wattage, the more heat is going to be generated. Wireless chargers already generate a lot of heat. I can't imagine how hot the phone is going to get with a 15 watt charger. There may be a very good reason Samsung is limiting the power of their charger.

If they were that concerned with what they wouldn't support the 15aw standard, but they do. Qi charging doesn't always make the phone that hot compared to quick charging. I have a Choetech fast qi charger (only 10W) I was sent to review and the phone is at about this same temperature as it is via QC 2.0 with a cable

Hello everybody and happy new year!
My original super fast charger which came with the phone won't magnetically charge my note 20 ultra
with the charging cable which I used with my Samsung note 8. I already ordered new pd 60w quality cables+new pd magnetic adapters.
Since I did not find any information -Do I have to buy new magnetic tips (which are stuck in the phone) or can I use the same tip which I used with my note 8? Are there any differences between tips?
Thanks for your help.
Eran
P.S - I am using my Samsung note 8 charger with the magnetic cable adapter in the mean time. The only problem is the slower charge....
If the previous setup didn't work for the new phone, you'll need the new tips too, most likely.
However, especially at the 25W fast charging speeds of the phone, I'd recommend you steer far, far away from magnetic chargers. Sure, it sounds like a nice idea, reducing the stress on the USB port, easy tear-away charging, and so on, but since most of these chargers are incredibly low quality, with bad contacts, you can expect a lot of loss, which manifests in the shape of heat. I remember with my Note8 I did the same, and the phone would get uncomfortably hot - and that was only 15W. Imagine what 25W would do.
The only magnetic chargers I trust are the ones specifically made and tested for the device - e.g. Apple's (old) MagSafe on MacBooks. And even those had heating issues.

The super faster charger doesnt play nice with alot devices iv come to find. I had an issue using a 2 in 1 charger/ aux adapter. The charger kept connecting and disconnecting. It seems to be some thing special to that brick specifically. Especially since its a 45w charger and I tried a ravpower 45w charger and it did not super fast charge my phone. Soo, yea. Super fast charging will only happen by way of samsungs official charger... which doesnt like alot other add-on devices (dongles, magnetic tips, ect).
Hi to all,
Can we charge S21U with 40W chargers? They are a lot chargers like Huawei, Xiaomi and etc... with 40W and more.
I believe the answer is yes - or at least probably. Most of those newer chargers are "Smart" in that they only provide the volts and amps that are needed by the device being charged. I may be wrong about that, but I don't think so - I don't think you have anything to worry about.

Pretty sure you can, I use a 45 watt "smart" charger on my NOTE 20 Ultra without any issue.
You can use any charger that supports PD (power delivery), AFC or QC2.0
Any 45 watt USBC charger out there is going to be PD standard so you'll be fine.
The downside is, it'll still only charge at 25 watts.
I am charging my s21U with an 40w charger, works without problem. not using 40 watts of course, but its working.
The phone, all phones in fact, will ONLY charge at it's highest speed the phone allows itself to receive, the charger doesn't matter, it can be lower or higher than what the device is recommended for. A lower power charger will just take longer to charge the phone, a higher power charger will just not charge at it's full power if the phone won't accept the full power from the charger.
I've been using the 90w charger from my HP Spectre X360 my S20 Ultra since I got it without a single issue, I still get about 2 days of use per charge on that thing, and now I've been using the same laptop charger on the S21 Ultra and it works just fine.
The phone fast charges normally, doesn't get super hot, works just fine, and I only need to keep laptop chargers around the house, it's great haha
I have a 45W USB-C PD port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or integrity/longevity of the battery by purchasing Samsung's 25W charger?

That's the charger I've been using w/ S21Ultra (25W from N10+) and I figured out I won't be needing anything bigger then that. Thanks to Samsung 'super fast charging' the 5Ah battery on s21U charges faster then 3.8mA Pixel 4a5G battery(with the same charger). +/- 1 hour and done!
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!
I'm looking for recommendations for a charging station (or multi port charger) that will activate super fast charging on my S21 Ultra. I'm looking for at least 3 or 4 ports. I see a lot of stuff that say up to 100 watt charging but none really say if they activate super fast charging on samsung phones. If it can 45 watt super fast charge my tab s7 plus also would be a big bonus.

25 watts is as much as I go with for this generation of Li cells.
45 watts doesn't charge that much faster and creates even more heat, stressing the battery especially on the deeper charge cycles.
Just replaced a swollen Li on my Note 10+.
I'm lucky it didn't damage the display... that's what you're risking. The bag pack Li's aren't very robust... I torn one apart recently.
If you go with none OEM cables and chargers they may or may not work. Troubleshooting fast charging issues is a real pain as it is.
I just got done learning that
Adding more potential variables will only add to the trouble when troubleshooting.

The original one that came with my 10+ after a year and a half is still functional.
It's gotten heavy use.
It outlived the battery
The 25 w brick/cable can be had for $20 now... I know because I pick up a pair when troubleshooting fast charging... now I have two. Yes, well... I'm more conservative now with charging limiting the time/% as well temperature and rarely going under 40% or over 80%.
Most times I use a damp microfiber cloth to cool the charge cycle as even a 20% midrange charge can top out at over 100°F. New batteries soak up more current faster and the waste heat comes with that when fast charging.
Li charging itself is a weak endothermic reaction but the resistive heat produced greatly outweighs that lesser factor.
My thoughts on the charging situation with the S21 Ultra
In the newer S21 series (as with the Note 20 Ultra), 45W super fast charging 2.0 support has been dropped (I suspect it has something to do with the findings stemming out of the Note 7 battery fiasco investigation). From the reports I've read, they seem to have invested a lot of money and resources in studying battery safety after that embarassment, and have a new lab dedicated to studying battery and charging safety.
Max supported input wattage on the S21 series is 25W (so called superfast charging) and then there is the regular 15W "fast" charging. There's also 9W and 15W wireless charging (latter only available vis proprietary Samsung wireless charger)
There isn't a very big difference in the charging times between the OEM 15W and 25W Samsung adapters - there's a differnce yes, but its not a huge margin - definitely not what a 66% higher wattage charger should provide (25W over 15W).
Heating during cable charging is present on the S21U both with the 15W and the 25W charger, way more than what I have experienced with Warp charge on my OnePlus phone. This is despite the much higher wattage used by OnePlus, thanks to the VOOC implementation from Oppo, with lower voltages and higher amperages, and letting the charging brick do most of the thermal dissipation rather than the phone. Samsung on the other hand uses USB PD 3.0 + PPS standards.
If you're using a wireless charger without a built in fan, you get an even hotter phone than with the 25W cable charging, despite a lesser charge throughput. It's objectively worse for battery longevity because the battery is kept at the higher temperatures much longer due to the slower charging speed. Heat and Li batteries don't mix well.
From my limited experience with various charging standards and different phone brands, my conclusions about the S21 ultra are as follows:
1. Regular cable charging works just fine on the S21U. I use regular QC 2.0 chargers lying around at home and they work fine for charging up the phone without wearing out the battery. I plug in the phone whenever i am not using the phone, like for 15 to 20 mins at a time and most battery experts say that multiple small top up charges are better than a high stress pedal-to-the-metal full charge.
2. 15W is the fast charger of choice that I would charge the S21 Ultra with, if I needed a quicker boost on a nearly flat battery. 25W performance doesn't justify the extra cost of the brick. If you already have a 25W charger, then use that - what I'm saying is, there's no point buying one thinking it will charge 66% faster than the 15W charger.
3. I avoid Wireless charging on the S21U with third party Qi chargers (these only charge at 10W or lower). The phone really heats up depending on the charger - and then safety protocols slow down the charging speed even further on an already inefficient power delivery system. I would either use the OEM Samsung fast wireless charger (15W) with built in cooling, or none at all. This ensures minimum charge time to full and active fan cooling - least thermal stress is what I'd look for here.
4. My phone's battery charge level usually ranges from 20% to 90% - i try not to let it run down to flat or charge up all the way to 100%. If it does so occasionally, it's fine - the phone can handle it. I just try not to let it happen all the time. Have you noticed how fast the battery falls from 100 to 99? and then to 95... but it takes way longer for it to drop after that? 100% charge is a very unstable state for the battery 85-90% is the sweet spot. And around 50% is the most stable state. This is why Li Ion batteries are shipped at near 50% charge by most smartphone manufacturers to provide longest shelf life (the company has no way of knowing how long the phone is going to sit on the shelves before being sold)
5. I don't charge my phone overnight. I know that good chargers stop supplying power once battery reports 100% charge, but it starts charging up again when battery drops to 99%, charges it back to 100 in a few mins, then it cuts out and battery drops again and the cycle continues many times during the night till you take your phone off the charger. We know 0% and 100% battery level are the highest stress states for a battery - yet we leave the charger connected overnight, maintaining the battery at 100% for 6 to 8 hours at high electrochemical stress level.
All this is inconsequential if you change phones every year. You can do anything with your phone if you aren't planning to keep it for very long. I personally use my phones for 2-3 years and like to keep the battery is as good shape as possible. The above charging discipline has helped me maintain good battery health on all my devices for an average of 2.5 years each.
Some readers may not agree with my assessment and recommendations. Please feel free to disregard them and follow whatever has been working for you over the years. My use case and lifestyle may be very different from yours and consequently your charging habits will vary. That is fine.
This is not a directive from me to anyone, nor am i a battery expert. These are just my observations and advice for people that may be looking for it. If you've already figured out your best cahrging protocol, I'm happy it works for you.

On my Note 10+ it fast charges at about 2%@minute until about 80%. Much faster than a 15 watt brick can at 1%@minute in snail mode.
On the N10+ it has to have a 25 watt brick for fast charging to engage. I believe this is true with all Samsung models that support fast charging.
For brief midrange charging which Li's prefer, it's perfect. A damp microfiber cloth and/or a fan to keep it cool.
The temperature rise is due to resistance mostly in the battery it's self rather than the method of charge. More VA per minute, more heat*.
Samsung ditch the 45 watt brick because it was only a small increase in speed mostly in the 5-20% charge range I believe it was. This had nothing to do with the N7 fireballs. However a full charge with a 45 watt brick is the most battery stressful charging routine.
Honestly I'm not worried about longevity of the battery on my phone. I usually only keep a phone from 6 to 8 months. I just want something that works.

I'm not either anymore. I now know that changing out my N10+ battery is well within my skillset comfort zone. I could switch to slow charge midrange partial charges vs fast midrange partial if I wanted maximum life.
I just don't want to get too stupid about it*.
A swollen battery is an immediate threat.
That should be a consideration as an "event" can be painful and de$tructive.
"My pants, My Pants are on fire!" Bah-ha-ha-ha
I've had things blow up on me and onto me... better think and move real fast, and be lucky.
It's always better not to test your limits as eventually you'll discover them.
*sleeping with a charging Li is a bad idea. In the very rare instance were an event to occur it could easily be the last one for you. Anyone who's been sleeping when a fire broke out knows this.
Some of us already know people who died sleeping during a fire as well. As you get older you will too
