Samsung Galaxy S20+ and 45W charger - Samsung Galaxy S20 / S20+ / S20 Ultra Accessories

Hey, is it safe to use original 45W Samsung charger daily? Got it for nice price ($25) from friend's shop.
I read somewhere it's not recommend to use 45W. Also I read S20+ supports 25W only.
Thank you for answers.

It is safe to use the charger but I am not sure if it will be able to charge it at 25W also.

So if I will use 45W, charging will be the same as with original charger?
Tried it, remaining time to fully charged is showing the same with both chargers.

I have the 45w charger. Charging speed depends on the phone temperature. The phone slows down the charging when phone temperature gets high. It's marginally faster than the one that came with the phone. But it's super fast charging for the first 30 minutes or so compared to our of the box.
So i use the 45w charger at office when I need to charge the phone fast and seldom fully charge it as I would unplug it and go somewhere else.
At home I just plug in the charger that came with the phone for overnight charging. Perhaps not the best to leave it charging overnight but I need a full battery next day.

Even if the charger provides 45w, the phone will only pull what is needed from the charger itself. So if the phone limits itself to 25w, then thats all it will use from the charge available.
Equally, if the charge provided is lower than the maximum the phone can use (i.e. 25w phone but 15w charger), then it will use the maximum from the charge available.
Chargers these days offer a multitude of different voltages and amp ratings, but they are smart and will only send what is requested by the device that is plugged in so there's no chance of accidental over-voltage.

I too have the 45W samsung travel charger and did a comparison on power draw compared to the 25W charger that is included with the phone. I used both the USB C cable that came with the phone (Black) and the thicker cable that came with the 45W charger (White), while measuring the power draw using a power consumption meter that was plugged into the wall between the charger and the outlet. My phone was at 40% charge when I tested. The results are shocking.
Included 25W charger
Phone's Black cable - 27.9 W
Charger's White cable - 27.2 W
Samsung 45W travel charger
Phone's Black cable - 29.7 W
Charger's White cable - 31.3 W
The similar power draw explains the charging speed difference of 10 minutes which many reviewers on youtube have observed. Taking another step, I have read that the S20 Ultra requires the charger to support PPS to achieve (10V, 4.5A) in order to charge at 45W. So why does the 45W travel charger only support (15V, 3A), (20V, 2.25A), (3.3-11V, 4.05A), (3.3-16V, 2.8A) and (3.3-21V, 2.1A)? Even the best case scenario would be to use the (3.3-11V, 4.05A) PPS profile and set it to (10V, 4.05A) to give only 40.5W. I smell a rat.

Interesting. I have also measured power draw but my results are bit diferent.
45W charger was getting up to 41W for 4 mins.
On overall charging speed 0-100% the diference is 10mins, but after charging 20mins I'm getting 54% on 45W and 37% on stock.
17% in 20mins it's a lot of difference.
45W is slowing down up to 1A after that to cool down the phone. 25w have similar behaviour.
Baseus 65W PPS chargers triggers SFC 2.0 but it takes more than 2h to charge fully. Amperage is oscilating as hell.

my Huawei 65w laptop Charger charges my S20U much quicker than the 25w charger i find...

I have been continuously testing and found that if your phone has less than 30% battery and the battery temperature is under 33 ºC, it will charge at 40W. After that, it drops to 30W for the remainder of the charge and then drop again to 20W when the battery is above 80%.
Next step is to find a good battery data logging app which logs battery percentage, battery temperature, charging current and time. Surprising to find that not many apps can do this. Even the Battery Charging Monitor app doesn't log all that data.

Solar Charge ?

Does anyone know of a solar charger that will actually chearge the prime ? i have a freeloader solar charger with an internal 1200mAh battery that can ouput 5v 500mA and a Hymini Wind charger that has a 1200mAh internal storage that can output 5v 850mA
Both of these can alledgedly charge an Ipad but neither of mine seem to have the grunt to kick the charging circuit into life on either the tablet or the dock.
I just I want something that i can use to keep the unit topped off whilst i'm travelling around Greece
Before anyone says it, i understand the limitations of solar charge. from using it for my phone know they take many hours to charge their internal batteries and the loss associated with then dumping that charge into your device.
Not at 5v it won't
You'll need 15v to charge at normal rate, or 12v at a slower rate. 5v it will only charge completely off, and then only very slowly.
i take it that's just the tablet and not the dock ?

Either. The maximum input voltage for either is 15v.
ok cheers,
I thought it wasn't charging at all but i've read elsewhere that the charging light will not come on and that it will take up to 16 hours to fully charge on 5v
if that's true then if the solar charger is 1200mAh and is pushing out 500mA then it's only going to be able to charge the pad for just over 2 of the required 16 hours (i think ?) before it's depleted
I'll run some experiments and see exactly how much charge it will put into it overnight but it doesn't seem like it will be a practical thing to use.

Is it possible to see how many Amps of power are being provided?

Just curious if there is an app or something similar that would show how many amps are being provided when charging through a wall charger/USB powered hub? The reason I ask is that I'm thinking of buying a powered USB 3.0 Hub. The adapter that came with our phone says it's 2 Amp, so I am assuming our phone can pull 2 amps for charging. Just wanted to verify in some way that a 2 Amp dedicated port would really work for this phone.

When I get home, I'll download the kernel source and see if I can find out how much power it draws during charging. I doubt however, that it will draw 2A during charging as most chargers are rated to supply more power than the phone will accept.
Yeah, 2A seems like that could melt a battery charging that fast. Someone sent me a private message and told me to try CurrentWidget. I threw that on the phone and it registers as 1A while charging. But it appears like the widget doesn't break it down with decimals. For instance it could be charging with 1.8A and wouldn't know it. I put it in a standard USB port and it reported as charging with 0 Amps but the battery was indeed charging.
I took a quick look at the N7100 (International Note 2) source posted on Github by CM and it looks like AC charger is 650mA, USB is 450mA. It's a little hard to tell what exactly it's using for charging, so I'll try to verify that when I get home and have a chance to take a better look.

A 3100mAh Lithium Ion battery can easily handle a full 2A charge rate. The ideal charge profile for Lithium Ion is a CC/CV profile, starts at constant current between like 3V and 4V, which most LI batters can take a rate of 1C, meaning it can handle a charge rate of 3.1A, recommended charge rate to achieve the most possible charge/discharge cycles is usually 0.2C so for a 3100mAh battery that would be 620mA. Once the charge gets to the correct voltage it gets to constant voltage and charges until termination current usually in the 100mA range. So yes, it can handle a 2A charge no problem.
Hey there. I very much appreciate that breakdown. Makes me wonder why they dropped the amps so much during charge.

If this is true (first time I've seen this anywhere), that would line up great with the 650mA max charge rate I found. Also, I downloaded the VZW source, and it doesn't look to significantly different from the N7100 source, at least as far as the charger stuff is concerned, so I would say they both probably have a max charge rate of 650mA.
I appreciate the info and time you both put into this. I guess it means a 2A usb port will be slight overkill. Even changing the charge rate to a higher value seems to indicate a lower battery life. Makes you wonder how apple did it's math for the ipads charge rate. The battery must be huge to accommodate a 1.1A charge rate. Or they are sacrificing battery life for fast charging.
Wont the kernel dictate the charge rate no matter what the charger is rated at?
If the kernel is set for a charge rate of 650mA (0.650A), then why does the Note 2 have a more powerful 2A wall charger, while the GS3 has a 1A wall charger.

The original nook color 7" came with a 2A wall charger and that was 2 years ago... both my note 2 and nook color charge about the same rate (quick to 99% and slow to 100). The charger is probably cheaper to make at 2A rather than anything and plus it could be used to charge future devices. Also if you used a 1A charger to charge the note it might possibly get warm/hot from running at near full capacity.
Im using my OLD blackberry 700mA wall charger to charge the phone at night while im sleeping. No problems with heat.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Essential Phone can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
They claim that a 5 mins charge gets you 5 hours of battery. 1 hour and 30 minutes for a complete charge.

Apperently its like 30 something Watts. Unbox Therapy found this on the charger.
27W to be exact. And on another video review, it showed 5v @ 3A and 9v @ 3A on the charger. So this thing should charge pretty quick and I assume is just using the native USB-C Fast Charge capability which is just fine.
I got confirmation from support that it is using USB-C PD for charging. No QuickCharge.
So this is all false then...

Yup, that would be a lie. Just because you have a 835, they would have to still implement QC themselves in order to leverage it.
And I believe Qualcomm loves to charge a pretty penny to flip that bit on for your device.
The device may still charge pretty quickly, but we will need some reports from those who have it in hand.
Anyone with it already have AccuBattery installed and see what the charging speed is plugged into its charger?

From a review I watched, they said that the charger is capable of Charing 5 hours of usage time in 5 minutes.
I tried my s8 charger on it, the charger quickly heated up and stopped charging the device
When using the S8 charger, it show slow charging... Sucks
Soooo... What's wrong with using the included charger?
And Samsung uses some other form of Fast Charging that's proprietary to their own devices. It isn't Qualcomm quick charge at least at the generic level. Essential just uses the USB-C 3A fast charge ability which you will have to get separate from both Samsung or QC2/3.0 stuff which is a bit of a pain, but really not surprising. Same as the Nexus/Pixel devices.
It shows Charging Slowly with my Anker PowerPort 10 charger for some reason - even though it is 60W capable and nothing else was plugged into it. I'm really hoping I don't actually have to use the bundled charger just to get it to charge quickly. That would actually be really annoying. I rarely use included chargers since I have Anker PowerPorts everywhere that I need to charge.
I plugged in an Ailey quick charge charger. It first said charging slowly then changed to charging rapidly.

That's because it will never fast charge a USB-C Fast Charge device. You need something like this since this device does not have Qualcomm quick charge.
That 60W charger doesn't really support any modern Quick Charge, it just supports the max 2.4A charging for things like Tablets and whatnot.
For those using Quick Charge to the PH-1, it is only compatible with QC 4.0 and not QC 3.0 or below. QC 4.0 is compatible with Power Delivery (PD) that PH-1 uses.

Quick charge or no quick charge, I'm pretty sure it's supposed to charge faster than 3% overnight. It still said charging slowly when I got up this morning and said 5 days until full. It had actually only gone up 3% in the past 9 hours.
My battery is at 96% so it may not be the most accurate test, and it was over 1000mah on initial plug in and then slowly went down to what's on the screen shot after about a minute.

Question Xiaomi Slow Charger will give any problem to Mi 11x?

Hi Guys,
I know we always have to use the default charger but this is also a fact that the fast charger is not always good for the phone's battery life. We can use it sometimes when we are really required fast charging.
I have a Xiaomi original charger 5V, 2A. I use to charge my device 20-80% with this charger. My phone will not get heat up like it compared to the situation when I charge with a fast charger.
Please tell me, is there any problem if I'm not using the default charger that comes in the box with the phone? I'm using that cable but with the Xiaomi slow standard charger. Will it be safe for both the phone and charger?
Thanks,

I AM USING XIAOMI 18 WATT POWER BANK WITH ORIGINAL XIAOMI CABLE AND I ALSO BOUGHT 50 WATT POWER BANK SO I CAN CHARGE MY DEVICE AT 33 WATT WITH 50 WATT Xiaomi POWERBANK COZ IT SUPPORTMax 33 watt charging and whenever i play games i use 18 watt powerbank to charge so it reduces heat.. . I didn’t face any issue …but never use fast charging while playing high graphics demanding games.sometimes while playing games if battery low then i use 18 watt powerbank to charge while play…
yeah thanks for the reply.
sometimes, in the case of need, I will use the fast charger otherwise I will always go with standard 5v 2A charger.

Question S23 Ultra Slow To Charge?

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.

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.

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.
