Hi guys,
I just got my S20 and to my great disappointment, it doesn't charge off one of my USB-C PD power supply (Navilock 60W PD) and it also only "slow"-charges from my Apple 87W USB-C charger. At least, when it is on. When powered off, it charges with both chargers (although I cannot tell if it fast-charges). Does anyone have an idea why or perhaps how to fix this? Also let me know if you're experiencing a similar issue.
Edit: What else I tested:
Same PS, Samsung cable (still doesn't work)
Same PS with different phones (Mi 9, Mi 10, both work with fast charging)
Same PS with laptop (Dell XPS 15, works @60W)
Samsung PS with Samsung cable (works)
Hi,
You cannot fix this issue because samsung's fast charge only works with samsung PS.
they use the USB-PD standard but Galaxy smartphones detects whether it is samsung hardware or not (to avoid the risk of overloads, electrocution and fires with counterfeits and maybe for others reasons... )
in addition, it is indicated in the charging parameters that to ensure proper functioning of the device, you need to use officials Samsung accessories.
If you need an additional charger, you'll have to buy Samsung.

According to some owners of the Galaxy S20, S20+, and S20 Ultra, their phone either refuses to charge at times or the charging keeps getting interrupted every few minutes, requiring them to unplug the charging cable and then plug it in again. This happens with both official and third-party chargers – wireless charging is unaffected. A device restart apparently helps for a while before the issue crops up again. It doesn’t seem to be a hardware fault, as some users say the issue was introduced after a software update.
It also doesn’t seem to be very widespread, as there are very few reports on Samsung’s community forums over the last few months, and most of them are from Germany. Of course, even a few reports should be investigated, especially when they have to do with a device’s charging capabilities. None of our devices here at SamMobile are affected, but we have reached out to Samsung and will update you once we get a response.
In the meantime, do let us know if your Galaxy S20, S20+, or S20 Ultra is plagued with these charging issues by leaving a comment below.

Using a standard USB-PD charger, the S20 range will only charge at 10W. This is because the S20 charges at 9V (I measured it at 8.3V though) and not at 12 or 20V which the USB-PD charger can provide. As a result, the next available voltage is 5V Check if your charger supports 9V output.
Newer USB-PD chargers Rev 2 AND with PPS will be able to negotiate 9V charging, but even so will be limited to up to 3A output. So you only get 27W of charging at most even with a 100W rated USB-PD Rev2 charger..
Hi, my S20+ (g9860) fast charges with a MacBook Pro charger. Don't know if it's to do with the chipset? I.e. exynos Vs Snapdragon?
I have a Xiaomi Fast Charger that's capable of providing 27W @ 9v/3A. Initially when used on my S20 G9810 SD865 model, it showed slow charging. However, I found a setting under Settings - Device Care - Battery - Charging. There is an option for Fast Charging but that was toggled off. Super Fast Charging and Fast Wireless charging were toggled on. I turned on Fast Charging and now when I'm using the Xiaomi charger, it shows Fast Charging when plugged in.
i have a 65W pd charger that works perfectly with my 20+, fast charge works without a problem, even got a non samsung cable to go with it.
i got it on ebay: https://www.ebay.com/itm/Baseus-GaN...-0-for-iPhone-USB-Phone-Charger-/184010071627

Looks like you found a very good charger that can replace the included Samsung charger. What current does it charge at? Does Accubattery say it is charging at 5000-5500 mA?

Does it say Super Fast Charge 2.0 when you charge with it? Or just Fast Charge?
I have a number of chargers that I use with my S20 Ultra. Depending on the combination of charger and cable that I use, I can get the following charge modes:
1) Fast Charge - 9V/2A - QC2.0 / Samsung AFC
2) Super Fast Charge - 9V/3A - USB PD
3) Super Fast Charge 2.0 - 9V/4A - USB PD with PPS

i have no idea what current it uses, and my phone is already fully charged so i guess accubattery won't show the max current until i drain my battery a bit, i'll try it later.
it doesn't say super fast charge 2.0 since i have a s20+ (that doesn't have it, only the ultra has it) but it does say super fast charge, and the original charger does say the same thing.

It just says Fast Charge.
With Fast Charge toggled on, Accubattery shows 3000 mA
With Fast Charge toggled off, Accubattery shows 1800 mA.
I have the S20 with the 4000 mV battery.
To fast charge the S20+/S20 Ultra, you need a newer fast charger that not only support PD, but also the new PPS specification where the power supply can output 3.3V-11V (continuous programmable) and at least a 3A at those voltage. For 45W charging, you further need a PPS power supply which can output 5A at 3.3V-11V.
Most of the existing USB-PD power adapters do not support PPS and thus will not be able to super fast charge the Note 10+/S20 range of phones. The newer PPS adapters are slowly appearing now.
My Xiaomi charger is a 27W charger that does 9V/3A. Once I toggled the Fast Charge option on, I can charge my S20 using the full 27W.

On my S20U, Accubattery reports
Super Fast Charging 2.0 shows 6000 mA (with 45W Samsung travel charger)
Super Fast Charging shows 5400 mA (with included 25W Samsung charger)
Fast Charging shows 3000 mA (QC3.0/AFC)
Cable Charging shows 1800 mA (Fast charge turned off but using QC3.0/AFC charger)

I have the Samsung 45W travel charger which is supposed to support everything that is required to get the quickest charging from the S20U, but it still only charges at 30-32W.
Hi,
I have similar issue with my S20 (Snapdragon 865)。I have tested 2 different brand PPS chargers and 1 PD chargers and official 25W charger, the results are very weird.
1. Baseus 45w pps charger: S20 shows super charging but only get 9.3V*1.4A while Xiaomi Mi9 get 9V*3A.
2. Xiaomi 65w pps charger: S20 shows super charging but only get 9.2v*1.5A while S5e tablet get 9.3v*1.9A.
3. RAVPower 45w PD charger: S20 shows fast charging and get 9.2v*1.4A while S5e tablet get 9v*1.9A..
4. Official 25w pps charger: S20 shows super charging and get 9.2v*1.7A.
All results are tested when the phone battery below 50%。
What I found is my S20 's charging speed is never above 16 Walts when boot into system with whatever chargers and cables. It only charges at 25 Walts when the phone is turn off.
And another weird thing is after a firmware update (I forgot which one.), my S20 won't show fast charge when I use a PD charger and only charges at 5V/2A. It can only get fast charging when I do the following steps (turn off fast charge option before charging and plug the cable and wait for the 'You can turn on fast charge' popup shows and click OK), it now get the fast charge feature till next reboot.
I hope someone can reach Samsung and report to them. Thx!
Sorry for my bad English.

Have you checked what your CPU and battery temperatures are when you charge the phone while it is on? The S20 will slow down charging if it is too hot.

The battery temperature is around 36C. The room temperature is around 26C. Since my Note10 and S5e tablet can charge normally with these chargers, I still think it's a firmware bug that cause the problem.

Wondering if anyone else is having a similar issue..
I have an Anker PowerPort Atom III Slim 63W with a 100w USB-C to C cable
When plugged into the 18w or 45w port on the Anker charger, the ZF3 activates Super Fast Charging for a few seconds, then turns off, then a few seconds later starts charging again, then turns off etc
The only way to stop this is to disable Super Fast Charging on the ZF3 - but then its just standard, slower charging
Charger works fine with Note 10+5G (Super Fast Charging) and other devices
Cable works fine with other chargers
Using a different cable with the Anker charger doesn't fix the problem
Is the Anker charger just simply not compatible with the ZF3?
Does the Samsung 25w brick charge it normally?
Erratic fast charging is one of the signs of a battery failure.
It sounds though likes it's incompatible with the Fold.
If fast charging parameters aren't fully met, it will disengage.
If charge start battery temperature is below 50-70F
Above 101F
If battery charge state is above 75-90%
If display/phone is active*.
*screen off listening to bt with Poweramp doesn't skew the charge curve.
ZF3 Super Fast Charges perfectly fine with other chargers, including a third party WJOY USB C Charger 65W that I use.
The problem is only with this Anker charger.
I think the Anker charger is simply incompatible with the ZF3...
The issue is 2 fold. 1 - that charger doesn't support PPS or the new version of PD, so you can't get super fast charging. And 2- It supports PD, however it's an older protocol that only Google and Apple phones use for "rapid charging", so you can only use standard fast charging.
So it sounds like the phone is trying to handshake the PD signature from the charger for super fast charging, but fails once it realizes it doesn't actually meet the proper PD specs. Charging is very rudimentary, so it's going to keep trying because it keeps seeing "PD capable charger"
Simply disconnecting the charger from the mains, waiting 5mins, and then reconnecting everything seemed to do the trick - The ZF3 now Super Fast Charges. Seems like it was just a glitch with the Anker charger and it just needed a reset. Thanks for all your help
I would like to know if the OnePlus 5T's charger will be able to charge the S22 or is it better to get the Samsung 45W charger or some other make with the future in mind?
There is also the Samsung Note 8's charger lying around but that seems to be a 15W compared to OnePlu's 20W and not sure the Note 8's charger will work.
All chargers will work. OnePlus' super fast charging won't work since that goes against your typical quick charging spec, but if it'll charge. The Note 8 charger will also work, but will charge at your typical 15w speeds.
Skip Samsung's 45w charger and just get a third party 25w or 30w charger since not even the 45w capable phones charge at 45w consistently and generally throttle down to roughly 30w.
25W charger is all you need. I have the Anker Power Port for my S22 Ultra and it charges from 20% to 100% in 80 minutes. A 45W charger is only slightly faster. Not worth the extra cost.
Im using the charger that came with my A20 to charge my s22 using fast charge. works well when not using the phone.
normally I charge my phone while sleeping. but today I didnt. when I went to bed it was at 95%, when I woke up it was 18%....
Thank you for responding.
I also have a OnePlus 5T 20W charger, wondering if I can use that.

But 20% to 100% in 80 mins is bad, when I'm in a hurry to go out I should have enough charge on my phone but with this 25W charger, it is not possible. So I'm going with a 45W charger because I used Redmi K20 pro with a 33W sonic charger, it charges 0-100% in just 40-45 mins!!!
I have the HyperGear wall charger works great.
Isnt the Samsung S22 (Base one) capped at 25W max capacity. Only 22+ and 22U support 45W charging.
I too upgraded from OnePlus5T, the S22 doesnt charge with it and shows 5 hrs to charge fully and for some reason, the battery was discharging while connected to the 20W OnePlus charger. I dont think its compatible, ideal and safe choice would be to go with 25W charger from samsung for 1299 if you do not have any previously owned ones.
I'm getting so sick of Samsung. All I want is a watch that can make/take calls away from the phone and has ECG and oximeter. I got a Galaxy Watch 4 LTE but couldn't find a carrier that would activate it. Now I bought the same watch with the required S21 FE. Neither watch nor phone included a charger. I know from previous experience how difficult it is to find the proper fast charger for a Samsung device. What wall charger should I get for these? What about a desktop wireless charger?
I'm also seeing lots of conflicting info about which CPU the S21 FE has. So which is it?
Download CPU Z and you know which CPU you got.
Buy a 25Watt charger.
I have the original Samsung ep-ta800n 25W fast charger (amazon) without problems.
When I leave something to recharge all the night I use an old charger 5V 500 mA that protect more batteries with his slow charge.
So is the S21 using Power Delivery instead of Adaptive Fast Charging?
S21 fe and other recent Samsung use the super fast charging.
A correct 25 watt charger is samsung ep-ta800X where X is various letters (I suppose for different colors, different plug…).
Well I bought a 25W Snug wall charger and get Super fast charging but weird thing is my phone now says it doesnt charge fast charging nor super fast charging... even thou it takes roughly 1h20min to fully charge
