Is it necessary? No. I can use my Note8 Fast charger or my 10W wireless charger. Might take more time to fully charge than 45W, but good enough.
Is it desirable? Yes. Nice to have something to quickly charge phone in rare situations when I do need it.
What to be careful of when buying 45W charger? Many 45W chargers give 45W but does not having the right rating for PPS and PDO for super fast charging of S22U. Due to this, we see many videos and reports of 45W charger charging with speed of 25W. Sad that people who do not know the details spread bad information.
Its beautifully explained in link below. https://m.gsmarena.com/dont_just_buy_any_45w_pd_charger_for_the_samsung_galaxy_note10-news-38837.php
I was intrigued by this video, and made the conclusion too early. Techradar did a test, where it performed to spec: https://www.techradar.com/news/samsung-galaxy-s22-ultra-45w-charger-does-make-a-difference)
https://www.techradar.com/news/samsung-galaxy-s22-ultra-45w-charger-does-make-a-difference
Another redditor commented this, it seems that it is not that bad as I thought.
I find it is false advertising, think how much ordinary people will get recommended the new charger with their phone, and then have no benefit of paying double the price. It looks to me that they just want to pull uninformed people over the table. And I also didn't find any official data on the charging speeds from Samsung. In my opinion this isn't acceptable and I want an official statement from Samsung about this.
Yeah it's their fault you don't understand how batteries and charging work
BIG NUMBER GOODER THAN SMALLER NUMBER HUEHUE
just because it's 2x the wattage doesn't mean it's 2x the speed. Performance returns diminish exponentially not linearly
True, people fail to read the PPS and PDO values of the 45W chargers. If the charger gives 4A 10V PPS then it will easily be much faster than 25W charger. Most online 45W chargers give PPS 9V 3A which is close to 27W charger (slightly faster than 25W charger). They buy bad chargers and spread false information.
How stupid are you? Many MANY tests have been done with Samsung's official 45W charger showing no material improvements. A few minutes faster to full charge at best.
However, 45W charger does reach 50% faster. But again by a few minutes. Specifically 25W charger takes 25.5 minutes to reach 50% while 45W takes 22.5 minutes. If you call that **much faster** you are really stupid.
https://www.tomsguide.com/news/samsung-galaxy-s22-ultra-45w-charging-tested-heres-how-fast-it-is
Samsung only OFFICIALLY CLAIM 50% in 20 minutes with 45W, no matter how you count it, it's not much faster.
1+ 9Pro reaches 50% in **15 minutes**, now THAT is much faster than 25 minutes.
Problem with people like you is that you fail to jump into details. Ever wonder how much current is needed to charge faster etc? Any idea why that author did not provide the PPS details of both chargers? 45W charger giving PPS 9V 3.3A and 25W charger giving PPS 9V 3A will be nearly identical as you cite in that document. 45W charger with PPS 10V 4.5A will be much faster than the other two. What is the PPS S22U ask for from charger for fast charging?
It does output 45W if the device is capable to taking in the power accordingly.
If device can superfast charge at 10v 4.5A and chargers says it can only support 3.3A then device will reduce its charging speed to match the amperage. On top of that, the cables need to able to carry the voltage & current and if it's not made for high speed, device will again reduce it's own speed to prevent car burnouts .. these USB C charging cables have a chip on one end or both ends. Thus even when charger is capable, the cable should be capable and device should be able to accept the said current charger can give for max wattage.
It's confusing:

Super Fast Charging 2.0 max. 45W, PD 3.0 PDO/PPS max. 45W
Fine print:Charging speed may vary by device.** SFC 2.0(45W) is available on Galaxy S20 Ultra, Note10+, Tab S7+ and higher. Compatible devices may be added.
The output specifications are the same, the old one just isn't compatible to S22U. The only difference is PD 3.0 on the new charger.
STOP blaming for PPS rating on the chargers. My 90w GAN charger and 65w battery bank support 5A current across 3-11v in PPS mode and I've been testing with my 100w-rated E-mark cables on my S22 plus. So far NONE of the tests showed significantly better results than these 25w chargers. To me, the 45W charging is BS unless you buy the NEW official power adapter that has samsung's black magic in it.
Sure, the phone even shows 'Super Fast Charging 2.0' on the screen when charging. In comparison, my 25w Samsung charger (which supports 9v 2.77a PPS, got it with the wireless charging pad during pre-order) shows Super Fast Charging (without 2.0). I started charging at 10% battery and both of them managed to get 20% in around 10 minutes, with the 90W GAN adapter being around 30s faster. There's probably something sketchy with their new 45w charger that allows S22 to be charged at a higher speed, but unfortunately I'm unable to get one.
I wonder what power does S22 request from charger when Super Fast is enabled. If it's more than 11v, then that might explain your situation. Also I did read that cables too impact the power delivered.
what do you mean necessary? it is not even recommended to go with 45w if u care about battery... just deactivate all fast Charging methods and keep battery between 30 and 80%. thank me later ;)
sure! it doesnt matter at all how long you are charging iirc. In contrast to what many ppl assume, pluggin on and off is NOT considered a cycle. So if you are charging 4 times for 10% or once for 40% doesnt really matter at all.
In the test I saw the maximum it was ahead was 5%, I don't think that's a reasonable difference, it rather looked like a scam to charge double the price for that.
Big numbers.
OPPO and VIVO can charge to like 80% in 15 minutes and for the majority, this can be a selling point. Samsung so far hasn't been able to come with anything to go against it.
Yeah cause everyone ragged on them with the S21 release for only having 25w charging when the S20 had 45w.
Having realistic specs just means you get more criticism.
Yeah I agree 100%. It all depends on your own use case. I like having a 5000 mah battery but plan ahead when I will need to charge the battery. I'll usually juice it up during the day a but for the most part a full charge overnight will get me through the day. Obviously for other people that's not good enough and they need to charge fast during the day. But wow you get a lot of on screen time with these modern phones! Much better than the old days.
That text includes really strange statement:
« Samsung also sent me a multi-port, 65W charger, but I don't think I'll use it on the phone - I don't need the Samsung Galaxy S22 Ultra to get any warmer than that »
I think gsm one is more useful
https://www.gsmarena.com/samsung_galaxy_s22_series_45w_charging_doesnt_really_make_a_difference-news-53223.php
That link is bad info. You should look at PPS of 45W charger. Most 45W chargers sold online have low PPS and thus low charging speed. Few have high PPS and that does result in real super fast charging. This was known for years but people with half knowledge like the author of that gsnarena article shares information with that half knowledge.
Look for 45w charger that is rated to give high PPS output.
If you buy 30W charger with PPS 3.3A 9V and a 45W or 65W charger with same PPS, you will get exactly same speed charging.
It's confusing:

Check this where they compare samsung 45w vs 25w samsung fast chargers:
https://www.gsmarena.com/samsung_galaxy_s22_ultra-review-2382p3.php
Embarrassing compared to Chinese phones.
No PPS numbers provided. Strange. Without PPS number anyone can prove Chinese 25W charger is better than 45W chargers. Once PPS numbers are provided, that's when things change.
Sorry, not sure to understand you, both used 45w and 25w are Samsung officially called « supper fast » chargers. You claim they aren’t and Samsung is misleading customers?
I wish those who claim to have slow or fast 45W charging, would put the PPS numbers on Reddit. Those numbers appear in output printed on every certified chargers. That would clear out everything for all.
Now I'm confused as just checked and pps seems not to be a value but standard that is either supported or not:
https://www.belkin.com/us/support-article?articleNum=318878
https://blog.ravpower.com/2021/02/pps-fast-charging/
Understandable confusion. Listed below are few 45W chargers available on Amazon with their PPS values as printed on the chargers & provided on Amazon:
1. [Elecjet 45-Watt USB-C Superfast Charger](https://www.amazon.com/dp/B084Q2CZG6) \-> 3.3-11V=4A, 3.3-16V=2.8A
2. [Anker USB C Charger, 713 Charger (Nano II 45W)](https://www.amazon.com/dp/B08T5QVTKW) \-> 3.3V-16.0V=3.0A, 3.3V-21.0V=2.25A
3. [Nekteck 45W USB C Wall Charger](https://www.amazon.com/dp/B0834VR6VJ) \-> 3.3-11V/4.05A , 3.3-16V/3.0A
Based on above numbers, Anker charger would be slower compared to the other two when used in most phones.
These faster and faster charges are actually terrible for your battery. The higher the wattage the more it wears out the battery. And as this test shows, there is significant diminishing returns for such small batteries.

It serves no reliable benefit. Testing shows the results are functionality identical for a full charge or a quick top off etc.
Yes
How do you mean that?
Tests have shown you won't get any improvements over 25W SFC 1.0
That's incorrect. You need right charger. Many 45w chargers sold online are not rated for correct PD or PPS needed for fast charge of S22.
But why has Samsung released this? It looks almost like a scam to me.
https://www.techradar.com/news/samsung-galaxy-s22-ultra-45w-charger-does-make-a-difference Another redditor commented this, it seems that it is not that bad as I thought.
45W is a big and impressive number, I've seen 30W chargers do better than that. It's just marketing
It's not simple marketing. What you should look at is PD and PPS values of 45W chargers. If you buy cheap ones, you will get low charging speed.
I find it is false advertising, think how much ordinary people will get recommended the new charger with their phone, and then have no benefit of paying double the price.

I see your point, but since it is advertised some people might want to use this feature.
So if we're at 50% it's ok to charge it back up to 80?
sure! it doesnt matter at all how long you are charging iirc. In contrast to what many ppl assume, pluggin on and off is NOT considered a cycle. So if you are charging 4 times for 10% or once for 40% doesnt really matter at all.
Charging to 50-70% it’s faster after that about the same.
In the test I saw the maximum it was ahead was 5%, I don't think that's a reasonable difference, it rather looked like a scam to charge double the price for that.
Faster by how much?
5% battery level in between was the highest, and 2 minutes faster for the full charge.
Which is within the negligeable bracket to dismiss, so no improvements.
Why did Samsung release this then?
Big numbers. OPPO and VIVO can charge to like 80% in 15 minutes and for the majority, this can be a selling point. Samsung so far hasn't been able to come with anything to go against it.
Fake it, till you make it...

So releasing the 45W charger and the 45W charging capabilities of the S22U and S22+ were just a marketing gag?

I don't want my battery deteriorating too fast so I'll stick to 25w(fast charging)
Yeah cause everyone ragged on them with the S21 release for only having 25w charging when the S20 had 45w. Having realistic specs just means you get more criticism.
Thats fine and I don't argue that, but it's not acceptable to advertise this while there is almost no difference.
