I tried using two approved chargers. The Anker Nano II and official samsung 25W charger. Getting capped at 15W. Am I doing something wrong?

Same here, I don't think it'll ever go to 25W. One of those Samsung unfulfilled wishes? Am using the original 25W charger and DevCheck Pro readout shows oscillating wattage between 18.8-17.3(battery level ~35%) Maybe they could fix it w/OTA software?

I use this charger and the screen-on charging value goes up to 4 Amps (as reported by Accubattery) so I guess this is the perfect charger for 25W charging. Also in the specifications, the rating is mentioned; some are very near to 25W.
If you want to figure out the wattage use the simple formula W=V*I where W=wattage in watts, V=voltage in volts and I=current in amps.

Been using the very same EP-TA800 adapter, "25W" as Samsung misinterprets it because it only goes to 18W max or so: (started at 26%, second pic 45min later)
You are right, I can confirm also that the 25 watt charging is just gimmick.
When your phone are low battery (under 30%) you only get 25 watt of power pulled from your charger for a minute or so.
Then the continue charging speed are about 18 watt.
With AccuBattery pro app, after several various charging time, I get average of charging speed = 90% per hour
Usually I charge my battery from 20% to 85% in 44 minutes. With phone screen off about 30mins.
You can also check what charging levels you are supporting by going to Settings -> Battery and device care -> Battery -> More battery settings
Just a heads up for anyone not coming from the Z Flip 3, though, that Samsung reset the evolution of USB-C on the series. The Z Flip 3 launched with 3.1 and 15W, while most other phones were 3.2 and 45W charging.
If you follow Samsung's upgrades, you may already know that the difference in capacity between the Z Flip 3 and Z Flip 4 is 400mAh. Ironically, the difference between the S9 (15W) and S10 5G (25W) when 25W released was also 400mAh.
Samsung's linear progress aside, the charging difference is only noticeable in the first hour. You can read more about it at https://www.sammobile.com/2019/05/02/how-fast-is-samsung-25w-super-fast-charging where they compared the standards in depth.

Next week getting a new Note 4 - and zerolemon 10,000mah battery!
I need to deep cycle battery 6-8 times to get phone to display the current vbbatt % correctly. The manufacturer for zerolemon says turn off fast charge and charge 12hrs each time.
That being said, with fast charge off, can I use a 5v 3.5 amp charger I see on amazon and possibly charge the phone faster than 12 hrs like normal is using a 2.1 amp charger?
Anyone tried this with let's say even the stock battery does the battery actually charge faster due to the increased amps or would it be a waste and still charges at the slower 2.1 amps?
I never deep cycled the battery and the longest discharge I got was 1 week with 16 hours on screen time...you just need to make sure you use an updated kernel with the zL fix.
The amperage rating is the max the charger can put out. The Note will draw the same amperage on either charger because they are both 5V.

But will the phone charge faster on 3.5 amps at 5v vs the 1.5 amp or 2.1 amp the stock charger puts out? I am getting ZeroLemon and need to deep cycle the battery a few times and am trying to have it fully charged in less than the standard 12 hrs - was hoping a charger with more amps would cut down on the 12 hrs lol
http://www.amazon.com/gp/product/B00WN86VYQ/ref=ox_sc_act_title_8?ie=UTF8&psc=1&smid=A3RPN0HBLXDN8Z
i just used the stock fast charger on my zerolemmon with fast charge on and i never let it go the full 1 hours. Ive had insane battery life with it so i dont think it matters

Your Note 4 will draw a maximum of 1.9A on a 5V standard charger and a maximum of 1.66A on a 9V Quickcharger. If you multiply these values, you will get your "charging speed" in Watts: The maximum is 9.5W on normal charger and 15W on a quick charger.
Using a higher rated normal charger (eg 5V/3A) will NOT INCREASE charging speed. The Note 4 will never draw more than 1.9A on 5V.
Using a lower rated normal charger (eg 5V/1A) WILL DECREASE the charging speed. The Note 4 will notice that it cannot get 1.9A from the charger and drop the current. Bad and/or long cables can also influence the charging speed negatively.
Also noteworthy: Quick charging will only work when screen is off. As soon as you turn your screen on, the charging speed when connected to a quick charger will drop from 15W to an extremely slow 5W. The only fix for this horrible Samsung joke is a custom ROM like CyanogenMod.
You can charge your Zerolemon battery nicely with the original Quickcharger that came with the phone. That will do 15W and is as fast as you can possibly charge.

Wow. Good info. Thx. Now a ton with a hack to draw more amps lol. Hmmmm lolol
So... Phone is supposed to charge at 45W but, from what I've read, this is not really true...
I do not have the original 45W Samsung charger but a 3rd party multiport 90W charger, with 2 PD usb C and one A port.
Till yesterday I was using a standard usb C to C cable and phone would display "fast charging" with an estimate of 1h from 15% to 100%. Not really a good performance I'd say. Today I bought a certified 100W cable with a display showing charging speed (usb C to C). With this cable two things change: phone displays "fast charging 2.0" and charging speed has slightly improved: less than 1h from 12% to 100%. Still not fast enough for a 45W charging... And as a metter of fact after 5 minutes the display on the cable stops at 28W...
This matches with lots of articles that complain for the same problem...
I also have a Xiaomi 12 Pro with dedicated 120W charger + dedicated usb C to A cable (charger has A). I'm saying dedicated, because with any other cable (standard usb C to A or even the above 100W usb C to C with adapter) the Xiaomi displays "turbo charging" while with original dedicated Xiaomi cable it displays "120W max" and is indeed blazing fast: 15 min for a full charge!!!
What is strange is that if I use the Xiaomi 120W charger with dedicated cable on the s22 ultra, phone displays only "fast charging" without the "2.0".
Now... I'm not trying to compare charging speed of s22 ultra to 12 Pro: Xiaomi can achieve such a speed because the phones have two separated batteries that charge simultaneously, thanks to a power splitter that takes the 120W input and splits it into two 60W, one for each battery.
What I'd like to know is what's going on with the s22 ultra. I understand that a basic cable is not enough to deliver 45W, reason why I bought a better cable, yet I was expecting a big improvement, while it improved charging speed of less than 10 minutes. And as a matter of fact I've never seen 45W on the cable display. Maybe I need an original Samsung 45W charger instead of a 3rd party one?
Search the forum, there is a few topics regarding 45w charging... I have a 65w charger and 5a cable and the charger has all the necessary properties/charging formats needed to fast charge 2.0 the samsung, but it doesn't. i don't even get the fast charge 2.0 notification....In the end the difference between the 25w and 45w is very slim....will be a waste of money to purchase the 45w samsung charger....check the other discussion.....my charger takes basically an hour from 10-100%...it's good enough for now
Well good enough if not compared to the blazing fast xiaomi's 120w charge
Most of the time, it's only several minutes charging time difference when I have a "Super fast charging" charger or a "Super fast charging 2.0" charger connected. 45W charging seems to be over hyped by Samsung and it's not using full power to charge all the time.
I have the original new 45W charger and the phone charges from ~ 0% to 50% in approximately 20 minutes as advertised. It is faster by around 22% in comparison to the 25W fast charger between 0-50% state of charge. Afterwards they both charge in almost same way with the 45W charger being max 10 minutes faster by reaching 100%. You need a PD & PPS charger. There are only some 3rd party ones that manage to do same as checked by androidpolice:

My charger is compatible with FC 2.0 but as I said it depends on the cable. Real problem is that 10 mins faster between 25W and 45W is a real joke. Given this phones is energy hungry then... With the Xiaomi 12 Pro I don't even care: 5 mins and I get 30% of charge, although you need proprietary charger and cable

It depends on what you want. For example I am perfectly happy with my 25W charger which comes rarely in use because of me charging wirelessly and without fast charging over the night but I bought the 45W one to have the possibility to get that extra speed between 0 and 50, and my girlfriend gets my old 25W one for her base S22. Samsung has a different approach to fast charging and for me 120W on Xiaomi or 150W on Oppo/OnePlus is something I do not need although I am curious why Samsung did not make the same move yet. Just split the cells in two or three, give each cell a maximum of 25W and boom, you're in the mix and nobody will complain.
On the other hand they lied to us about last gen 45W charger which was useless so it is fair to say that their battery & charging department is almost on the same bad level as the Exynos software team if not actually worse than them

2 cells is exactly what Xiaomi does
Reg Samsung, that's my point: they indeed lie, it's not a 45W phone. Full stop.
I have two Super Fast Samsung 25 watt chargers. One for my S22U and One for my Tab S7+ and both can charge in under an hour. 45 watt chargeers just wasting your money, and extra wear on the battery for a tiny bit of improvement. Not worth it to me.
Hello, 4 days ago I bought this new s22 ultra with exynos processor, but it is generating many doubts that the loading of the device I feel that it is going very slow or more than it should be.
It always takes 2 1/2 hours or more to charge 100% with a 47w essenger charger or a Samsung charger that I have from the s10+ which I think is 20w and 3a
Measuring the charging speed in a plant or portable battery that I always have mark at most 20w but never stays at that speed, usually oscillates a lot between 10 and 16w, and stays much more at 10w which makes me weird and annoying because it is very low
I do not know if I should buy a Samsung charger of 25w since from what I have seen the 45w charge does not work, and that charger would be 5A unlike the one I have that is 3A but I do not know if it would make any difference.
I would like to know if it happens to someone else or if it is something normal, this makes me think a lot about changing phones since the charge seems to be very slow.
Please would appreciate any help, I will also leave attached the charging settings I have placed and the measurement I have made with my charger, I serve any advice you have please
Charges fine (inc. super fast) with Samsung charger ex Note 20

It's a QuickCharge 3. It's an old standard for Snapdragon phones and Samsung S-series before s20. To charge fast You need 45W PPS PD 3.0 charger. PPS is crucial.
If i remember correct samsung 45watt charging is 9v x 5A not 5v x 9A. If you have 3A the maximum you can charge is 27w (9v x 3A) but if your charger is 5v then only 15w (5v x 3A).
Exynos very fast charging battery and I tested 8 hours on TV Pingu

Turn off adaptive battery. It will change the charging speed for battery life savings. It's a new feature but has been making people think fast charging modes aren't working.
I have some Anker brand USB-A to USB-C charging cables and just the wall wart (is there a technical name for those things?) from something... probably one of my old Samsung phones... it says "Adaptive fast charging" and output says "9.0 V === 1.67A or 5.0 V === 2.0 A".
( know that stands for "volts" and "amps", but I don't understand what the rest of it means... 2 Amps is "faster" than 1.67 Amps... I think... but what makes it charge at one speed or the other?)
My real questions:
1) Will using the USB-A to USB-A cable that came WITH the Galaxy S22 Ultra make a difference in charging speed?
2) Do I need to get a different "wall wart"? If I want one that supports USB-C plugging into it, I do, but will it gain me anything?
Thanks.
Edit: I guess tehnically it's an "AC Adapter" or a "power supply brick"...?
See how what you have now performs. The best/fully compatible would be Samsung own charger. And any decent quality cables
I use my original charger from my Samsung Galaxy Note 4 on my S22 ultra. It charges it about 90 minutes. I suspect this is the same charger as yours.
1.67amps x 9v is 15.03watts.
5.00apms x 5v is 10.00watts.
15 Watts is a nice steady rate to be charging your battery at.
45w...is really too fast if you want your battery to last more than 2 years.

45W is nothing and won't really degrade your battery much. Also, keep in mind, that batteries degrade regardless if you use them or not, they have a shelf life. So, in 2-3 years you will mostly need to replace your battery anyway if you plan to keep your phone for that long (assuming that you want the battery to be at it's "full" capacity after 2-3 years).

Even still...I'll keep slow charging my phone...knowing that it will last 5 years.
My note 4 battery outlasted the actual phone. The touch screen packed up first. The battery still lasted 6 hours screen on.
I replaced it with a Note 9. Again...the battery was fine...and original. Same story...6 hours of screen on time.
Now I have a Note 22....or S22 Ultra.
I have used the Note 4's charger for all of these phones...with my 10watt Kosee wireless charger. Even on the Note 4...with a wireless adapter.

It's still 10 Amperes into the battery.
I'm often running ~10 Amperes into my dual 224 Ampere-hour 6 Volt "golf cart" batteries.
They also weigh about 130 pounds more than your battery!

It doesn't push 10 Amperes into the battery.
PPS charging is pushing from 3.3V to 20 Volts at 2.25Amps, it's dynamic charging and it depends on the device's state (temperature of the battery, the charger, the capacity of the battery).
I'm not sure where you get this information, and not trying to be rude now but maybe you should check up on both PD and PPS charging protocols that Samsung uses before assuming it's charging at 10 amps.

1. With Galaxy S22 there is an USB-C to USB-C cable not USB-A (maybe a typo on your side). That cable is rated for the full power charge the device supports, that is 45w. It can make a difference if you are using it with a proper charger (that's the actual naming for the "wall wart"...it is called "charger" or "wall charger" btw).
2. Yes, you should get a different one if you wanna charge faster. Your actual charger is a (so called) "fast" charger with the charging power varying from 15W to 10W. Your phone supports from 25W up to 45W, that are the "ultra fast" chargers.
I'd suggest to get at least a 25W charger, also there are some extremely good Anker alternatives (even better that original Samsung chargers), look for Nano II 635 or 615 Anker chargers.
If you wanna keep your phone for an extended period (like 4-5 years or more), you might wanna activate that battery protection charge that only charges it till 85% and will preserve it for a longer period. If you switch phones after 2, even 3 years, don't bother, charge it as you like fast or slow till 100%

If the charger is rated at 45 Watts and sometimes actually delivers that:
45 Watts / (maximum) 4.3 Volt battery > 10 Amperes
Maybe they are PWM-ing it or whatever, but the peak current is > 10 Amperes.
Ok, we can subtract the efficiency of the buck converter, but it's still in that neighborhood.
What would happen if I bought and used a 65-watt charger? Would it automatically drop down to 45 watts to charge my S22 Ultra? Could it damage it, etc.?

1.Q. Yes.
2.Q. It not gonna damage it if not pushed to full 100% or discharged completely before connecting.
Sorry to hijack this thread, but is there a decent wireless charger, that will give me fast wireless charging with a Spigen powerarc arcstation pro 65w charger? I have tried about 3-4 cheap crap ones, and they all give reg wireless charging of about 22% for an hour's charge.
The S22U‘s maximum wireless charging rate is only 15 watts. I use the Spigen PowerArc ArcField 15 watt wireless charger, which is powered by a conventional charger via USB C cable and works very well charging my S22U.
Is there a difference in charging speed between an Anker Nano 3 and the official Pixel 30W charger? I bought the Nano but accubattery tells me it only charges at 17 watts while the P7P should go up to 23 watts. Should I return it and get an official Pixel charger? Or is it normal that it doesn't reach 23 watts? Adapative charging was off while charging.
Since Anker is a well known brand, I would test it another charger. It very well could just the device only pulling 17 watts at that moment. I have multiple Anker chargers, cables and hubs at work and home. I have never had a charger fail or come up short on the rapid charging.
I have Anker cables and I noticed they charge much slower than the cables that came with and are designated for these devices. Still faster than my cordless charger.
Thanks for the replies. I'm using the official Pixel cable. I think I will order a Pixel charger and see if there's a difference.
I am using an Anker Nano Pro (20w) with Anker cables and my P7P charges in just under 2 hours which is only a few minutes slower than the official 30W brick.
This is a good read https://www.androidauthority.com/google-pixel-7-charging-30w-3226058/
Thanks, that's interesting. I will let my battery deplete further and see if the wattage is higher when charging from a lower percentage like that article says.
I am sure i have read in the past the Pixel 6 Pro over the whole charge averages only 13W, if your reading is for the average and not peak wattage then maybe 17W is right
Keep in mind that maximum charge wattage will drop off if the phone is doing things at the same time. Just turning my screen on and looking at the AccuBattery charging screen takes between 1-2W and there are spikes beyond that as apps do things.
It's not worth buying expensive chargers to get the highest wattage possible as it's a negligible benefit since the average is going to be way lower than the peak anyway. Both my OnePlus 9 charger and my Anker charger seem to peak around 19.9 watts with the screen on and they both support USB PD PPS.
