charging tests - whats the best charger?

Hey guys, as we all saw, the new note 20 charging specs isn't as good as the old one coming up to 25W rather than 45W.
But as for my past experience those on-paper specs aren't exact accurate and sure never fully explained.
unfortunately I don't own note 20 (yet?), so I can't share my highly detailed tests that I usually do, but those of you who own it and can share any data of test please write it down here.
Try to measure any of the following details:
* what charger(s) are you using? (Name / output powers / Power delivery version / etc... picture of the specs on it will be sufficient)
* what voltage and ampere (or watt) are being used (hold it few seconds to let it settle, it also should vary on the current starting point battery level, and wether screen is on/ off) (the more details you bring, the better)
* if you got no power meter than charging times could also be usefull (0->30, 0->50, 10->20, etc..)
after we get some tests here I'll sum it all up in a google sheets (like these: example1, example2, example3)
and after that we can get some recommendation of what 3rd party chargers are best to buy
If you are like me and like plugging a charger in every corner you probably want something good, with high speeds, and original is always more expensive than 3rd party ones so why not knowing the specs first.
Also we might find out that some charger can charge even faster than the original 25W one (what about 30W,45W,65W PD 3.0 chargers? what about PD 2.0? 1.0? etc..)
Your contribute will be highly appreciated!

I have an N9860 from Hong Kong. Normally I am happy to slow charge and have my charge settings set that way. Today, as an experiment for this discussion I enabled fast charging and super fast charging and connected to a 60W PD/QC4+ charger via a USB-C monitor.. The charger is branded Klearlook and was bought from Amazon in the UK a couple of years ago.
The phone is receiving/demanding only 15W at 9.2V, 1.6A. That is from 13% to 44%.
I removed the monitor in case it was interfering with handshaking protocols and it has had no impact on remaining time to full charge (now 58 minutes remaining at 46%.
Using the same charger I disconnected the PD cord and switched to an 18W USB-A port without a monitor. No change to remaining time to full charge.
So I'm getting fast charging, but not super fast charging from my combination charger - a charger that will happily run my Dell XPS 13 laptop from the PD port.
So then I unboxed the supplied charger and cord, previously unused. With the monitor attached I'm seeing 18W - 9V at 2A - and the phone says super fast charging, briefly, with the screen off and only the charging information displayed.
I'll just carry on as normal with my slow charging to 80% (thanks Accubattery) since that suits my needs perfectly well and should hopefully minimise battery degradation over time.

Thank you very much for that highly detailed measurement and review!
Results are pretty disappointing, your charger should have be good scenario
Hopefully (but doubt it) maybe others would find better results

The fact that maybe your PD QC4+ does not support PPS (the only way to enable 25W charging on Note 20 ultra or 45W on Note 10 plus).
Confirm that your charger does support PD with PPS protocol.
Yes, it's a bit annoying (to say the least) that note 20 is slower (downgrade) compared to Note 10 in terms of charging speed.

I have no idea about PPS - never heard of it until now. The charger is no longer available from Amazon. I bought it in August 2018. Maybe it predates PPS. Anyway, a Google search found what appears to be the same product here....

Yeah, no mention of PPS anywhere, only AFC on the 3 non-USBC ports (limited to 18W).
And you are right Note 10 and S20 (the ones using PPS - 25/45W are 2019 phones), so the power supply being a 2018 product may lack the latest protocols.
I have a Note 9 (2018 product) and no ”Super fast charge“...
I had the same problem (bought a 45W car charger), just to find out it lacked PPS protocol, so no 25W or 45W charging speeds. I Had to return it, and carefully search for an updated version (more expensive) supporting it.

I have several chargers I use, but without any real testing, it feels like my 45w charger from Samsung is the best experience. I attached my charging log screen shots. 1%-100% in 1hr 13min. I get the super charging icon through the entire charge. I will try the same test with the 25w charger and see if there is any difference. It feels like it charges just as fast as my previous note 10+ 5g, which is why I got this charging block in the first place.

Question 45W Charging requirements have changed?

Alright so I've got my S22U in, and it appears that the charging requirements for 45W Fast charging have changed relative to the Note 10+ I did have. Neither of my two chargers that previously charged the Note 10 at full speed charge my S22U at full speed. There is no "Super Fast Charging 2.0" indication on my display when I connect the chargers. So something has changed. Kind of a disappointment on my end, since there was no good reason to change standards/requirements. Does anyone have a new 45W adapter, yet?

I have the Spigen ARC 45w charger and even though it doesn't say "Super Fast Charging 2.0" (only without the 2.0) it charges at exactly the same speed as the original new samsung 45w charger (where it says 2.0) used in this test:

Alright I found someone on Verizon's website saying that the output voltage on the EP-T4510 charger goes up to 20V whereas my chargers only hit about 11V, even under PPS. So the Ultra requires a higher 20V voltage to get up to 45W, where my Note 10+ only required 11V to hit 45W. Makes sense now.
Verizon Review of Samsung 45W New Charger

The new charger has PPS [email protected] 2.25A. The old charger had PPS [email protected] 4.1A. If you were using the old charger, you need a 5A cable. There hasn't been enough testing with real volt/power meters to see what's going on, because all these youtube trash reviewers are just plugging something random in and measuring the time it takes to charge.

Yeah with the old charger I was using a Thunderbolt 3 cable rated for the full 100W charge spec (20V/5A) so the cable itself is def good.
EDIT - I just tried another USB-C cable, and got the 2.0 notification. So check the cables for sure. THanks for the hint.

Hi guys
I'm using Samsung 45W charger; EP-TA845XBEGWW. It delivers 21VDC at 2.1A, this gives 21x2.1= 44.1W and It's works perfectly for changing my S22 Ultra. It also got a lot of other charging modes, it runs PDO or PPS. USB type C in both ends. Hope this helps.

Yeah in my case it was a cable issue. The same cable that worked perfectly on the N10+ no longer supports 45W speeds on the S22U. So I am going to seek out new cables I guess. Thanks.

I bought this charger from Amazon.ca and according to the specs it outputs 21 volts @ 2.25 amps so should be able meet the 45 watt max charging capability of the phone. It's very compact. I'll verify when I receive the phone.

If it doesn't check your cables.

Use this 100w/5a usb-c cable (https://amzn.to/351pBUQ) with the Samsung 45w charger (EP-TA845XWEGUS) and it shows "Super fast charging 2.0". If you don't use the write cable you won't get the "2.0" type of charging.
I also got this charger hub from Amazon (https://amzn.to/3hcjnnu) using the same 100w/5a cables and it shows "Super fast charging 2.0". Nearly the same prices as the Samsung charger, but can do more. Works perfect for families as a charging hub. This was verified on both a new Samsung S22 Ultra and my old Samsung S20 Ultra.

General Charging the device feels very slow - Exynos

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

I have Samsung (i think 25w charger) and from 10% to 100% Max 1h10 mins

45w charges quick enough

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.

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 Do the wall wart and cable matter?

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.
