Question Super fast charging 2.0 on Baseus charger

[hand-filer]

Just get the Samsung 2.0 Chargers.
I wasted a lot of money on Belkin, Baseus and Anker testing out things.

Pretty much my story too. I received my Samsung 45 watt charger (On sale $20 off) this morning. Plugged it in and finally have it displaying super fast charging 2.0.

I have 4 Anker chargers that I bought. 2 are 45 watt charger, both with one USB-C port, a 47 watt with 2 ports, both usb-c, and 1 65 watt charger with 2 usb-c and 1 usb-a. I also have a Green 45 watt charger with 2 ports. All chargers charge SFC 2.0 if only my S23 Ultra is plugged in and using a 100satt 5 Amp cable. The requirements to have SFC 2.0 are you must have ag least a 45 watt charger and a 100 watt/5a cable and it must be the only thing plugged into that charger.

If you plug 2 or more things into the same charger, you will not get SFC 2.0 because the power is redistributed to accommodate both devices. It happens whether it is a GAN charger or a non+Gan charger.

So the answer to the OP is that you must meet the requirements listed in paragraph 1 to get SFC 2.0. And if plugging more the just your S23 into the same charger you will not get SFC 2.0 as power is split between devices. This is how it works.

I understand that and as you see I meet all the requirements. What I don't understand is why sfc 2.0 doesn't work when more than one device is plugged in. My baseus charger is 65w + 30w. So in terms of charging capacity, there is no issue there. The problem is that the sfc 2.0 protocol gets disabled when multiple devices are charged.

Hence 2 Samsung 45W SFC > 1 Baseus 65W + 35W

That is by design. Once you plug a second device into that charger, it lowers the wattage to your phone which in turn disables SFC 2.0.The charger is reallocating power to accommodate both device. A charger supplies a certain advertised amount of watts, for example my Anker 47 watt charger supplies up to 47 watts of power to one device if it needs that much, in my case 45 watts to my S23 Ultra. If I plug 2 devices into it, it will only Supply a maximum of 45 watts. That is not 45 watts per device, it is 45 watts total which means it is splitting that power between both devices. It is sending 25 watts to one device and 20 to the other device.

I did a lot of research on this prior to buying my chargers and the 2 cables I bought. I watched a lot of videos on it also.

Again, I understand what you're saying. My BaseUS charger is 100W. When I plug more than one device, the design is to split the wattage to 65W one one usb-c port and 30W on the other. Your Anker is 47watts so of course it won't supply 45W to one of the ports when plugging in more than one device to it, that is given. In my case, why won't it choose to supply the whole 45W sfc 2.0 to my phone when it technically can?

There are multiple layers to threads like this. Unfortunately, over the last 3 or so years the charging standards have been greatly complicated, kind of like RAM speeds with DDR5 in certain motherboards or brands not reaching full speed without everything exactly perfect.

I have a Baseus 65w charger with two USB c ports and one USB A port.(https://www.amazon.com/gp/product/B083J229RJ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1) I do get 45w charging from it on the s22 and s23, but it's only for a short period of time. During the bulk of the charge, and you can get a meter to measure this like I did between the cable and the phone, you will see anything between 24 and 35w max. After 80% it drops even lower.

You need the correct cable, the one that comes with the phone is good, otherwise, DO YOUR RESEARCH on aftermarket ones. You need a charger than will support it, and one that actually advertises the correct splits if you use more than one device. A lot of them just say a bunch of BS that isn't true, or is only true in certain cases.

This is an area where Oneplus blows everyone else out of the water and I really miss that charging system. The Pixel is way worse than Samsung so at least that's a plus.

I know people who have had good luck with this brand too, this is a link to the smaller one. They have a 100W as well. https://www.amazon.com/𝐒𝐥𝐢𝐦𝐐-65W-La...id=1684518955&sprefix=slim,aps,90&sr=8-1&th=1

Hope you figure this out. I went through this whole process when I first got my s22, it was very frustrating.

For the benefit of everyone, I tried out the newer 3 usb-c/1 usb-a 100W version of the SlimQ charger that @xgerryx recommended (https://www.amazon.com/dp/B0BQLZQNMM?psc=1&ref=ppx_yo2ov_dt_b_product_details) and my problems went away! Their support is top notch too. What's nice about this charger is that renegotiation will not happen as long as the total power draw from the charger is less than 100W. They call this "Reset-free Power Allocation". So I can charge my S23+, my Lenovo laptop, and my Galaxy Watch 5 at the same time without them affecting one another.

I don't understand why this is not a standard though. Why can't other bigger companies like BaseUS do it this way?

Thank you for your feedback, I will purchase one, how long does it take to charge your s23+. My s23 ultra charges inconsistently from time to time. I know heat can be issue but I make sure the room is cool for optimum charging and it's still inconsistent. One day it would charge really fast then another day slightly slower.

This is with the original 45w charger and cable.

turn off adaptive battery at settings.

I don't really measure how long but it's quite fast. Maybe less than an hour or so.

if the phone battery get hotter,then charging time increase than usual.
room temperature is important to charge the battery in normal timeframe.
usually 8 percents to 100 in 1 hours.
15 to 100 in 57 mins.

Yeah, that's what I experience. It doesn't really get super hot.

 

[kevindd992002]

Not sure what's happening with my S23+ this time but it starts to charge with SFC 2.0 at ~40W and gets down to a stable ~16W even if the battery charge is less than 50%. I base this on the reading of my Baseus 100W cable with LED display. It's not a charger issue because I've tried both my SlimQ and Baseus SFC 2.0 chargers and it has the same behavior. It's also not a cable issue because my laptop charges at 60W consistently with the same chargers.

This never happened before so I'm not sure what changed. In the past, it starts at ~40W and gets down to around ~33W while charging and that's fine. But 15W is too low, really. The weird thing is that it still charges from 15% to 100% in about 57 minutes or so, which is the expected time for SFC 2.0.

Any thoughts?

put a cooler at back of the phone before charging.
below 23 percent is 44 watt charging
after that 35 watt.

if very hot when charging ,only 14 watt.
need 1,5 hours from 7 to 100 percent.
if heat under control only 62 mins.

or you can charge the phone in air conditioned room.

if you see at screen SFC 2.0.
but at wattmeter only 14 watt.
and at screen full in 57 min.
reallity full in 80 mins to 90 mins.
depending on temperature.

I see. That makes sense. I will try charging it during the night time while the AC is on and see if it stays at 35 watts.

 

[kevindd992002]

@seriyah I'm charging it in an air conditioned room now and it looks like it still got a bit hot and went down to 14W again. If that happens and then I immediately place it very near the ac vents to cool down, will it charge back to higher wattages? Or will it never increase again when it already goes down to 14w?

 

[kevindd992002]

Ok, so it did increase back to 30+ watts when I cooled it down. It's not even hot to the touch so I'm wondering why it throttles down the charging time. SFC 2.0 is pretty much useless then if this keeps on happening.

may be protect the battery health.
you must ask samsung,why SFC 2.0 status at screen,but only 14 watt charging.
