fast charge is generally a feature that needs to be built into a custom kernel
Don't know about you but my S5 chargers incredibly fast compared to my SIII and Nexus 7. Even with fast charge on.
Agree, my S5 charges at 1.2A given a charger capable of this, and that is fast.

correction S5 chargers are shipped with a 2.0A chargers and it charges at that rate.

Yes, the S5 charges at 2amp. (Kernel reports 1800mah)
If your phone is reporting that it charges any slower than that, it's an energy deficiency of the charger supply, bad cable, or bad micro usb connection.
I use an app which reports charging current. With a standard micro usb cable i never morw than 1200 mA (and about 450 mA from a PC/mac usb plug)

While it's true that the phone ships with a 2A charger, the charging current does not exceed 1.2A AFAIK.
Gotta love MicroUSB 3.0.
It already charges from under 10% to 100% in a mere 2 something hours (bundled charger and USB 3 cable). You want something much faster than that???

Yes I think in the end it is something around this current. What the apps report is more "charging in 1800mA mode" and not really charging with continous/real 1800mA. If you like to know more exactly what the current is you may write down time/percentage values for e.g. every 5% of battery power starting with an nearly empty battery. Then you can draw an line of the effective loading current.
With the original charger you should be able to get stable 1800mA but if the loading circuit of the S5 really goes this high I did not check.
I believe it peaks at 1800mah with the screen off. It is 1200 mah limited when screen is on.
Sorry to awaken this post.
As most of you, my S5 reported charging at stable 1200 mA with wall charger, probably 1800mA when turned off.
But, I can say a custom rom unleash battery charging in the same conditions as stock rom. I get stable 1800 mA with LineageOS, even screen on, with original charger and usb 2 or usb 3 cable.
I am on the second Snapdragon ATT device and wireless charging is the worst I had in years. I dont know if its a software issue that can be fixed or a hardware issue. Both devices exhibit the same issue slow wireless charging or no charging at all just gets hot. I dont get it brand new phone thinking about going to last years S21 ULTRA if they give me the trade in credit. I have a note 20 ultra and it charges wirelessly just fine on any Qi charger. So disappointed right now.

I got this one. 15 watt wireless it's a 25 watt super fast charger so if you need a quicker charge you can always connect the phone directly without the pad. Both work great! Don't need that 45 watt charger this is perfect for wireless and wired.

Well I guess so if you having problems. Mine is the U.S. 512 gb Black version.
15 watt wireless and 25 watt wired.
Kept mine overnight with a 9W wireless charger and went from 2% to 21% over 8 hours...
Are you charging with the case on or off? I have been using my old Pixel wall charger and the OG Pixel stand. Plugged in my S22U chares quickly. If I use the Pixel stand it only charges with the case removed.

It could be the phone case, but, its not constant, I mean a day or two will charge full battery in 4 hrs aprox, like it should be, some other days 20% in 8 hours or so.. and its the same phone case

Mine charges Wirelessly in an hour. Snap Dragon 512gb Unlocked. Case is OtterBox Defender Pro and Charger is this one. If you do buy this one make sure you buy this exact model and not the one listed for $39.99 because that one only comes with a cable. The $59.99 one comes with cable and a 25 watt super fast charger. Will charge wirelessly at 15 watts or wired at 25 watts.

Sigh. I just double checked my preorder and this is what I have coming. Just like the review complaints, when I placed my order it had a picture of an adapter next to the charger so I logically assumed it was included. Now I see that they have 'updated' the product description to state that it is not included and I believe that was retroactively added because of all the negative reviews about this omission.
If I use one of the older 25 watt adapters that came with my Note 20 ultra, will it still work? I don't need it to fast charge. If regular charging takes a little over 2 hours from 0-100 with the phone plugged into the 25 watt adapter to a wall outlet- how much more longer do you think it will take to charge my yet to be shipped t-mobile S22 Ultra with this wireless charger?
Hello guys.
I wonder, what is the best model number for every charger.
I know only the 45W that EP-4510 is the good model, so whats the good models for the others?
Also want to know, if I bought a wireless charger from aliexpress(Baseus) with 15W, it will be good for my s22 ultra?
this is the charger:
https://www.aliexpress.com/item/4000695865761.html?spm=a2g0o.order_list.0.0.21ef1802WUKTQz
It depends on what you want.
Do you want convenience and less wear and tear on your USB port? Then wireless is best. Preferably a quality 15W charger.
Do you want fast, reliable charging, and don't mind plugging and unplugging each time? Then go with the 25W wall charger.
Do you want to waste the most money possible on a charger and seen nothing in return for your investment? Then the 45W is absolutely the best.
I think this the best option if you buy a samsung charger. Charges wirelessly at 15 watts and if you connect it wired then it becomes a 25 watt super fast charger. I have 2 samsung 25 watt super fast chargers. One for the Phone and one for the Tablet.

The cheap ones are just the pad. Their another one like the one I showed you above that $39.99 but that one doesn't come with the wall charger. The $59.99 price gets you the 25 watt charger and the pad. So if you need the charger too and not just the pad look closely at what is included.

You need a cable with USB-C on each end. The Charging Pad has USB-C and the 25 watt Charger also has USB-C So the old USB to USB-C cables won't work.

25 watt will be fine and shouldn't heat up the phone as much as a 45 watt. I always turn phone off while charging. You don't wanna be doing intensive gaming or bench marks while you charging. That causes a lot of heat.

Your battery will last longer with the 25 watt charger. The 45 isn't that much faster and it will definitely wear down your battery life faster than the 25 watt. Not worth it.

You can do it any way you want. You can wirelessly charge at 15 watts which is less strain on battery like if you wanna leave it on there over night while you sleeping which is what I do. Then if you need it charged quicker you just plug cable in to your phone and then you get 25 watt and should charge in less than an hour if you are charging fron around 15%.

Well it your money. I love the Samsung because it works and no issues. Shrug.
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.
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!

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.

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"...?

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.
