Unable to see "5V3A USB-PD" charging speed at all

I've had my 7 Pro 8/256 for a week now and was really hoping to see USB-PD 5V3A charging. In fact, I ordered a USB-PD USB-C power bank specifically for this.
I've also tried my Aukey PA-Y10 46W Wall Charger as well. USB-PD (PDO) 5V 3A | 9V 3A | 12V 3A | 15V 3A | 20V 2.3A.
USB-C to C Cables, U Green 3ft and Aukey 3ft.
When I connect the power, it doesn't indicate "charging rapidly" as it does on Pixel 2/3. Tested using Ampere. 1.7-1.9A even when the battery is only at 20-40% Far cry from 3A max.
When connected to the Dash Charger from my OP5 with OP5 cable, I get the standard 5V4A (3.3A in Ampere) of Dash with a Charging Rapidly logo and a blue lightning bolt.
Were we lied to? The article says it is supported but there is nothing indicated during my real world testing to show it actually is any faster than using a 5V2A charger. I livechatted with OP Support yesterday and they did confirm that OP7 Pro supports 5V3A USB-PD spec but the rep didn't understand what I was asking when there was no notification for rapid charging.

yeah on my PD charger it takes 1 hour 50 to charge from 20 to 100

If you want to see the actual rate of charging, I recommend using an app called 3C Battery Monitor. I use it to keep track of my phone's rate of battery drain when using certain apps or how fast something is actually charging. In order to save battery, I only have it logging the battery usage every 10 minutes but you can set the rate to be faster.
I'm my first picture below, I was purposely draining the battery down to 1% to test out the speed of the warp charger, but it was only sampling every 10 minutes.
My second picture is set to every minute.
Give it a try to test out the PD charging as you will have actual mA/hour figures to compare.

Thanks. Confirmed today that it does do 5V3A but doesn't show as "charging rapidly" using 3C Battery Monitor.
It is about 2.9-3.0A from about 25% until 70%. From 0-25% is about 1.5-1.9A and from 70% onwards it slowly decreased until it reaches 100%.
In total from 17% to 100% took 1h 47 mins. Not exactly fast but acceptable.
With the Warp Charger, it's 0 to 100% in about 1 hour flat. With a Dash Charger, it would be about 1 hour 30.
iPhone XS Max charges 0-100% in 2 hours 20 minutes with a 2.4A adapter

Mi 11 ultra charinging slowing even with 67w charger

Hai hello...bought mi 11 ultra ...1 week ago ....it comes with 55w charger ...and i purchased 67w charger separately ...
i dont know whats the issue ...its facing ...its charging very slowly ..with 55w charger ...it charges from 1 to 100 in 45 mins.
with 67w charger it takes nearly 45 mins to 50 mins to complete from 2 to 100 percent ...i dont know whats the issue..bought the charger on mi offical site only and they dont have return or replacement option. How these youtubers able to charger there device from 0 to 100 in 36 to 38 mins. i think they just bought money from the mi company and faking us.
Did anyone facing this slow charging issue thought check the ouput voltage and current ..but most of the detector available in market can calculate upto ...30v and 5.1A but ...mi 67w producing power is 11v and 6.1A ..so the value produce by the detector will not be accurate ...anyone have idea whether its software issue ..or company faking us and ...i charged my device from 1 to 100 without clearing ram and then always on display on ...

As one can read here the charging power isn’t as aggressive as the 120w of last year’s Mi 10 Ultra. But 67w of wired charging plus 67w of wireless charging is top-notch, especially wireless charging. In testing, wired charging charges the phone to 22% in 5 minutes, 90% in 30 minutes, and it takes only 36 minutes to fully charge to 100%. Wireless charging charged up the phone to 14% in 5 minutes, 78% in half an hour, and it took 43 minutes to fill up to 100%. For supporting such a powerful wireless charging phone, Xiaomi has also launched an 80w wireless charging dock.

Question Charging speed

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.

Question How do you get 25W charging?

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.

Question Battery

First off I run accubattery pro. I'm trying to guestimate if my phone is actually charging at 25 or 45 watts.
It shows around 25 if I have it set in settings to single cell battery mode. If I have it set to dual battery mode it says around 45 watts..
Anyone know the specs of our battery? Is it a single cell or 2?

It's a single cell lol... Try battery guru, it's better imo.

Exactly, it is a single cell. Using a USB tester during charging with a PD compatible charger 65 max (no PPS), can run only Super Fast Charge but no 2.0 type. Up to 60% it runs at 27 watt 9V*3A, above 60% it reduce to 15 watt and 10 watt above 85%. Super Fats charge 2.0 with peak 45 W requires a charger that supports PD and PPS protocols with 45W min power or above.
