Question S23 Ultra Slow To Charge?

[DUTCH Van Atlanta]

I don't yet have a 45 watt charger, so I connected the 25 watt charger from my S20. It says it will take 2 hrs to charge from 15% to Full.

My S20 would charge a lot faster than that. Is this normal?

I guess.
pixel 18W charger is 2h20.
iphone 5w is 5h15
LG 10w near 3h

I might get a faster one, I have the 20W oneplus one, but it wont work on the samsung... dash charging tech not compatible

Not sure if the S20 charger uses PPS charging protocol that S23U "requires" but 2 hours for 85% sound fine if it's not charging at 25 watts.

Thanks. My S20 with that charger would charge 85% a whole lot faster than 2 hrs.

45 watt charger should arrive tomorrow. Hopefully, it will go faster.

Yes, but as I mentioned, S23U requires PPS protocol to charge at the "advertised" speed. Just because the charger is 25W, it doesn't mean it will charge at 25W if it's missing the required protocol. Hence why I wrote I'm not sure if S20 supports the same PPS as S23U uses. In order to get 45W charging speed on S23U the charger needs to be PPS and the cable needs to be rated at least at 5 Amps.

That's what should be coming tomorrow from Amazon: Anker 313 charger and 543 cable.

Why Samsung doesn't include these with the S23 is a shame!

Well, some OEMs don't include a charger with their Flagships nowadays. Samsung isn't the only one.

That seems a little slow.

Make sure fast charging is on in settings. As you plug your charger in, it should say that it's Super Fast Charging

If it doesn't, try a different cable

If that doesn't work, go for a different charger

My phone keeps saying moisture detected, when there isn't, it's fked up, some chargers work, most dont

when you want to start charging your phone,make sure phone battery temperature is normal.
if you use continuously then charge it,charging speed is lower.
don't depend on status SFC or SFC 2.0.

you need watt meter cable or watt meter to know actually the real time charging speed.

if very hot,from 45 watt down to 15 watt charging (SFC 2.0)

if you want to charge from 10 to 100 in 1 hours use 45 watt charger,you need a cooler room temperature.
or you need a cooler at the back of the phone in 33 degree celcius room temperature.

if you wat to charge wireless 15 watt,it is the same.
battery temperature can make it slower charging.
status fast wireless charging is not the benchmark for charging speed.
SFC 2.0 is the same ,not the benchmark for charging speed.
you need a watt meter cable to know the real charging situation.

My S20 charger initially shows SFC as active when I plug it in but then it drops down to normal charging. Looks like I am not the only one with this issue so guess I will be buying a new brick.

Anyone got a good suggestion on which ones to get? In addition any good 12v car chargers that support it too?

The Anker 313 charger and the Anker 543 cable work for me.

I've had old HTC and Motorola phones from years gone by that took ages to charge. When I got the opportunity and the cash to buy my Samsung, I made sure I got a charger and cable that could super fast charge. From less than 10% to 85% capacity in just a few minutes. Wow.
