that is a 9w, and will display fast charging on the s22u . it came free with my s22u

several of my old ufo samsung fast chargers display fast charging. they are like 9w or so.
my 3 non samsung branded wireless chargers do not display fast charging, and the speed is much slower. these display fast charging on older samsung phones.

the charge time eta is much much longer when fast charging is not displayed with the off branded chargers. so say 9w fast, vs a 9w charger not fast charging is most definitely not the same. it is what it is, I can only add an observation and a data point.

I guess, samsung is now recognizing original accesories.
 
When I was getting the message on my old 10W charger there was a checkbox to not see it again. I also turned off the fast charge setting and was not getting the alert.

I bought a Chinese 15W charger and turned it all on again. I have a screen saver running (display on) while charging with no problems.

I couldn't get the Battery Charger Monitor to chart thru a display off condition. It always restarted the chart when the screen came on. I'll check the history over time after charging a bit.

I'm not sure. But every 10W "Fast Charge" wireless charger I have will not show fast charging. And they are official Samsung.

But my 15W chargers, including both my generic Chinese wireless chargers in my car, all show Fast Wireless Charging.

Either way, it doesn't really matter. It's still 10W whether it says Fast or not.
I didn't say anything factually inaccurate, nor did I get upset. Things said in the imaginary world of the internet don't upset me. I had actually already forgot about it until you replied just now and I got a notification.

If you think what I said was being "upset," then you might be a little over sensitive. Sorry if it came across that way.

Again, it's your charger. Get a 15W wireless charger and it will fast charge. You don't have to believe me. But companies change specs on phones, yearly. Just because your precious phones fast charged wirelessly at 5 or 10W doesn't mean this one does.
His issue and my issue are exactly the same.
I've been using note 9 on OFFICIAL 10W samsung FAST wireless charger. On S22u, it's still saying" Fast Wireless Charging".
On my 3rd party device wireless charger 10W in my car, Note 9 DOES show 'fast wireless charging' but S22U says "It's not compatible with the device, it's slowing down the charging speed. -> wireless charging"
I also tested my gf's cell phone S20 or 21 on the 3rd party charger, it says like S22U.

It seems like Samsung did some **** update on those new devices.


Btw, it's proving that 10W is not a culprit here. it's something else

OK. My Chinese generic 15W chargers fast charge. My Samsung genuine 10W don't fast charge.

What we have is two sets of facts that are opposing, so really it's didn't prove anything. It did not prove that 10W is or isn't the culprit. Nor did it prove that Samsung did some sneaky update.

So welcome back to square after proving nothing.

You need at least a 25 watt brick to fast charge.
V×A=watts; 10 watts is less than half the power needed to fast charge. It's physically incapable of providing sufficient power to fast charge.

The charger also needs to electronically "hand shake" with the phone to enable fast charging. If the charger doesn't meet those protocols, the phone will not enable the fast charging option.

I know. but as you can see, it is fast charging on 10W, 5.0V 2.0A . the phone is S22U

Officially, Fast wireless Charing starts from 10W according to Samsung.
and Fast CABLE Charing starts from 15W -> super fast = 25W -> super fast 2.0 = 45W.

maybe you are confused between wireless and cable charging?

Yeah I don't use wireless charging ever.

An easy way to compare actual charging rates is with the screen off while charging. Between 30-65%, time how long it takes to charge 1 or 2% in seconds. For the N10+ on wired fast charging it's about 30 seconds for 1%. Slow charging 60 seconds or longer per 1%.
At 72-80% fast charging automatically ramps down then ramps down again at about 90% to protect the battery.
Screen on automatically ramps it down to a very low level as does under or over battery temperatures.
At about 103F charging stops completely.
Below 50-60F fast charging will not engage to protect the battery.

On my Note 20 Ultra, I was using a third party 15W wireless fast charger. Up until about around a year or so ago, I was getting Fast Wireless Charging until I updated my phone. Ever since that update, the phone would not recognize the fast charger that had been working. It now displays the same error message saying the fast wireless charger I was using is not compatible and now only slow charges. Nothing changed other than that update.

It's a known "issue" that Samsung does not acknowledge, probably to rope you into buying official accessories. See this thread https://us.community.samsung.com/t5...-not-working-after-recent-update/td-p/1732927

I bought a Huawei one two years ago, the problem you mentioned does not exist, and the S22ultra works normally.

I've owned two of the RAVPower Turbo 10W Max Wireless Charger with Universal Compatibility (lol) for a little over two years now, and both have operated with my Note 9 flawlessly the entire time. I received my S22 Ultra yesterday, and whenever I place it on one of the wireless chargers, the phone display a message in the notification drawer that says "This fast wireless charger isn't compatible with your phone, so you're charging at standard speed."

I did a little bit of digging on Google and various reddit subs, and it appears that several Samsung phones with One UI 3 and above simply will not allow fast charging with 3rd party wireless chargers. However, in some of my digging, I've seen some people report that they've had success fast charging or super fast charging their Samsung phones with 3rd party wireless chargers.

Is there any way around this with my current charger? It only maxes out at 10W, but I'm fine with that for now, if I can get it working. I'll eventually upgrade to a couple of 15W super fast wireless chargers, but I don't want to do it immediately if I don't have to.

Has anyone had success wirelessly charging their S22 Ultra with 10W or 15W 3rd party wireless chargers?
So sometime in early 2021, Samsung released an update to existing devices, which limited the compatibility of third party wireless chargers (even those with perfect certification). The rationale was, 3rd party wireless chargers were a safety concern as some users reported mishaps. Of course we know, the real reason is always, you guessed it, Money!

So Samsung grabbed the opportunity and pulled an Apple with the customers. Beginning then, only the Wireless Chargers certified under the SMAPP (Samsung Mobile Accessory Partnership Program) are able to charge Galaxy devices at their supported speeds, rest all other chargers are limited to just 5W charging speeds.

To confirm this, put your phone on the third party wireless charger that supports Fast Wireless charging (above 10W) and see the notification at the bottom of the notification panel. Just as you put your device on the charger, it will read Fast Wireless Charging, and then within few seconds, will revert back to Wireless Charging (5W) in the notification bar. Telling us that all this is software restriction.

Samsung calls 10W and 15W wireless charging as "Fast Wireless Charging". Galaxy S21 lineup supports upto 10W Fast Wireless charging and Galaxy S22 lineup supports upto 15W fast wireless charging.

Currently, products that support these numbers and which are also certified under SMAPP (Designed for Samsung logo) are hard to find. Even Samsung's own Wireless chargers from last year, only supported upto 9W wireless charging. They refreshed that lineup this year, with newer wireless chargers that support upto 15W wireless charging. But they are very overpriced.

Most frustrating thing is, even with reputed 3rd party accessories manufacturers like Spigen, which have been under the SMAPP for very long time, not all their products are Samsung certified. So you really have to carefully read the fine print while buying. "Designed for Samsung" is the logo present on the accessories which are Samsung certified, but whether or not that means they will support peak charging speeds, is another story. Currently in my country, Spigen only has a SMAPP certified wirless charger that supports 10W max charging speeds with Samsungs. It supports 15W charging with non-Samsung (Xiaomi/OnePlus) devices just fine, but for Samsung it is 10W and iPhones it is 7.5W

Based on my expeiences I'm going to have disagree with you. I'm using the following:
-UGREEN 30 watt PD fast charger
-INIU15 watt wireless fast charger
-Chargie charge limiter
-100 watt magnetic quick connector (cable to wireless charger)
12.27 watts continous @ 9 volts.

    I'm specifically inquiring about wireless charging.
    Fast wireless charging needs 15W to fast charge. 10W is standard speed. It's your charger.

    As a followup, I dug out my old Samaung brand wireless charger, which came out with the Note 8 or 9. It's labeled as a "Fast Charger," but only charges at 10W. When I place my S22U on it, it just does standard wireless charging. When I place it on the newer Samsung wireless charger which charges at 15W, it says fast wireless charging.

    So again, the standards have changed, and now 15W is considered fast charging. Kinda like when the old Moto Turbo Chargers were considered fast chargers, but only charged at 5W. Standards change over the years.

    Your 10W charger is still charging at 10W. It just doesn't say Fast Charging anymore.

    Also, make sure these settings are all toggled on. Straight out of the box, my Super Fast Charging and Fast Wireless Charging were on, but Fast Charging was off.

    Get a Samsung 25w brick/cable for around $20.
    They last years.
