Review of Aukey Quick Charge 2.0 wall charger (adaptive fast charging) w/pics!!!

This is a review of Aukey Quick Charge 2.0 (Qualcomm certified) wall charger. http://www.amazon.com/dp/B00QEX83LA/ ($16.99), product page: http://www.aukey.com/product/pau28-qualcomm-quick-charge-usb-adapter
This is going to be a quick review since we are talking about a wall charger, though it's not an ordinary one but rather featuring Qualcomm Quick Charge 2.0 technology implemented in our Galaxy Note 4 as part of an adaptive fast charging. I see more of these wall chargers starting to pop up, but want to be sure you guys/gals don't fall for ebay scams and rather go with a trusted brand names that has been around for awhile and offer a solid warranty and tech support. The idea of Quick Charger 2.0 tech is to implement a higher voltage adaptive charging (at 9V or 12V instead of typical 5V) to accelerate charging of your smartphone battery. A number of new phones and tablets can take advantage of this adaptive fast charging already, while this product is also backward compatible with older phones to charge at 5V. Furthermore, you have to keep in mind that max current rating doesn't mean that your older phone will be drawing more current, it shouldn't sink more than it's maximum current rating. Therefore this particular charger from Aukey is universal to work with newer phones and also backward compatible with older ones, even those that can't take advantage of 2A charging.
The product itself arrived in a small environmentally safe box with just a charger and user manual. It would have been good if they would include usb to micro-usb cable, but I guess Aukey assumed that we already have plenty of those laying around. Just please keep in mind, for a higher voltage/current fast charging make sure to use a higher quality thicker usb cables. Thinner "data" usb cable are not intended for high current, and as a matter of fact can current-limit charge resulting in overheating.
Overall, this Aukey Quick Charger 2.0 performed exactly the same as Samsung Galaxy Note 4 original fast charger, which makes it a great replacement or a second set to keep in your office or when traveling. The build quality is good, feels solid in my hand, didn't overheat - no complaints here!
Here are the pictures.

Thanks a lot for the review. I also bought two along with a pack of 4 usb cables from Aukey for 32 euros and its working great. I would never pay 35 euros for a single charger when all quickcharge 2.0 certified chargers work the same

Vectron, another great review. Thank You.
What glass screen protector are you currently using?

What a great review. even though there is no cable included

Priced dropped to $14.99.

The Samsung fast charger looks sleeker

It does but it costs 3 times more

Qualcomm quick charging 2, does that mean that it only works for the snapdragon version? Or would it work on the exynos version (N910C) too?

NICE!

it will "work" in the same way any charger for the exynos will, as a 5.3V 2A charger. It will not Quick charge. so you are probably looking at ~1:45-2hrs to charge vs ~1:15-1:30 for a full charge on the stock battery.
Quick charge doesn't really do anything for the extended batteries since there is a limitation (firmware maybe) of 3320 MAH after that the charger stops charging. So quick charging has to be disabled to charge the larger batteries. Quick charging worked perfectly with an anker 6400 battery that I now have. Apparently this is a zerolemon limitation
I have this charger as well. I do think it charges slightly faster that the stock charger although that could be wishful thinking on my part. There really is no way to compare them since they both charge so quickly (normally right around an hour from 20%-full) so a minute or two could be simply what the phone is doing in the background.
I also have the tenergy, anker, verizon quick chargers and with all of them the charge is very fast.

How hot does it get? I had a 2A charger that sometimes got too hot to touch... at some point it died.

Mine dosent. The phone does a little, especially during the first half of the battery

I just bought a 5-port version (with 4 Ai ports and 1 QuickCharge port) http://www.amazon.com/Qualcomm-Certified-Aukey-Charging-Included/dp/B00UV4HCL0
OP's review covered the QuickCharge port. How about the other 4 ports? Does the Ai really work?
Thanks!

Hmm... I've received mine today with one USB port, but it's strange that micro usb don't go all the way to my Note 4 F version, and don't seem to charge fast as well? When Samsung charger is plug in there is a notification "Fast charger connected" but with Aukey there is no such information. Is it possible that I've bought fake/faulty one? When plugged my Note 4 to Aukey charger I didn't see any changes of battery percentage (when plug in was 8%) after about 5min was the same with Samsung went from 8% to about 11%. Any ideas?

I have the aukey one with three USB ports. When I plug on the fast charge, the screen does say fast charge.

So in my case I've got fake one or faulty one. I'll post pictures how my charger look like.

Hi Guys
Today we will show you the charging analysis for the popular OnePlus Two smartphone.

You should read a lot of OPT reviews from different site, but as a brand which offer chargers, we will only focus on the charging analysis for OPT2. We will test the original power adapter, suggest for how to quick charge your device, and help to pick up the correct alternative chargers. Here we go:
First, Let’s check the original power adapter and Usb to Type c cable:
The charger is regular 5V/2A power adapter, the specification on the charger is:
Model: AY0520
Input: 100-240V 50-60HZ 0.3A
Output: 5V/ 2A
The cable is interesting, Oneplus redesigned the usb port again,which make you never worry which side to insert, and the other port is USB type C, this cable can be used for charging and data transfer. The total length is about 3.5ft.
So this charger don’t support higher volt,(9V or 12V) and We can confirm that, even the OPT2 use the Qualcomm Snapdragon 810 processor, however, the OnePlus Two don’t support Quick Charge 2.0 Technology, We test with our chargers which support QC2.0, It just can get 5V volt, never get higher at 9V. You should read this news from different source, It’s a pity that they drop this amazing features, but We still want to give it a test for how the charging performance.
First we test the no-load voltage of their original power adapter:
I don’t connect any device to the charger, just use the ammeter to test the volt is 5.13V. It’s in the normal range ( the normal range for the charger should be 4.75V-5.25V, any chargers’ no-load voltage exceed this range will have problems), and then we make the oneplus two battery to 0% and begin our test: Here is our test result with original oneplus two 5v/2a power adapter, and usb type c cable:
Time Baterry Current
4:40pm-4:50pm 0％-17% From 1.89A to 1.85A
4:50pm-5:10pm 17%-33% Keep at 1.85A
5:10pm-5:40pm 33%-60% Still at 1.85A
5:40pm-6:40pm 60%-98%
6:40pm-6:50pm 98%-100%
From the above tablet, we can see, in the first 10 mins, the oneplus two get very fast charging, battery charged from 0%-17% in the first 10 mins, and we check the charging current, it is from 1.89A at first, then become smaller till to 1.85A. And then in the first 30 mins, it get about 33% battery. ( compare with the quick charge technology, about 60% battery in 30 mins, the oneplus two charging is slow). But the total charging performance is not that BAD, It take about 2 hours 10 mins to get the full charge (from 0%-100%). check the current tablet, before 60% battery, it get charged always @1.85A high current, and after 60%, the current will change smaller, from 1.85A to 1.83a and 1.79a, and smaller, because that change is fast, we don’t record every current.
Now we begin to test the charging performance with our chargers:
no-load voltage for tronsmart wall charger and car charger ( all of our tronsmart chargers are conform with the international standard)
Use the Tronsmart Wall charger and Tronsmart USB Type C cable to charge the Oneplus Two:
The charging current is the same as the original power adapter. The oneplus two don’t support QC2.0, so our chargers can’t give it faster charging speed, but at least,we offer the same good quality as the original power adapter.
In our testings, we found some interesting things:
1 If you make the screen on, the charging current will directly reduce to under 1amp, and with screen off, the charging current can reach 1.9a.
With screen off:
With Screen On:
2 If you use a low quality charger which can ‘t offer enough 5V volt, the OnePlus Two charging current won’t higher than 1amp, the charging speed will be super slow.
So how to make the charging speed faster on OnePlus Two, here are our suggestions:
1 Use the original or high quality power adapter and high quality USB type c cable;
2 Don’t use your phone all the time when you charge it, with screen on, we can see the charging current is really small.
Why Choose Tronsmart chargers:
All of Tronsmart Chargers are get certified by CE, ROHS, FCC and other certifications, all of our quick charges are certified by Qualcomm(you can find our name in the Qualcomm quick charge list), and we are also proud to be the featured quick charge brand in Qualcomm Official site. So You don’t need to worry the quality of Tronsmart chargers.
More and more flagship smartphone will support quick charge 2.0 technology, Samsung, Sony ,LG, Moto, all of these brand flag ship support quick charge, Tronsmart offer the world’s most abundant quick chargers. From 1 port usb wall charger to 5 port and from 1 port usb car charger to 4 port.
All of your families can get the fastest charging speed no matter what device they are using!
And more Tronsmart design a unique USB Typc C car charger for Oneplus two users, check it here:
Traditional, You need to prepare a high quality car charger, and high quality USB type C cable to charge your Oneplus Two in your car, but with Tronsmart USB Type C car charger, Never bother of this, plug our car charger , and charge your Oneplus anytime. also we offer another port which support quick charge 2.0 for your family’s Samsung, Sony, LG, Moto etc.
So above is our charging analysis for OnePlus Two, if you have any questions, feel free to leave comment below.

Good Job! Very professional! Look forward to more analysis such like this post.:good::good::good::good:

@GeekEric
What do you think of the below combination of components, will it achieve faster charging times for our oneplus 2 ?????
1.BlueRigger Rapid Charge Micro USB Cable - 6 Feet (does not support data transfer)
2.ImagineDesign USB Type-C Adapter : USB Type C To Micro USB
3.Amkette USB Wall Charger Duo for Mobiles & Tablets
I do not need your confirmation about any test results.
In theory, should the combination achieve faster charge times or not ??????

It charges from empty to full in 2 hours! why would anyone want faster than that? There's very little chance that a battery will be zeroed in normal use so charging times will be less anyway. Don't waste time and money trying to get a few seconds faster, just charge the thing overnight. Carry a power pack if you really need more than the battery can provide in a day.

My OPT needs 5h from 0 to 100%...

Are you using the original cable and powerbrick? Some third party cables don't support higher currents, which slows down the charging.

Yup. Everything original OnePlus.

[Official] ✘ This is how we ROCK ✘ ~ OnePlus Homescreen set-up's!!
Wow what a pro writeup... Thanks for going in-depth!

So this points out a major issue: it takes 4 times as long to charge if screen is on. That means +8 hours until full! What the ****, oneplus... Hopefully this is something we can fix with a custom kernel.

Nice and in details.. thanks

Amazingly detailed OP well done.
I have noticed that the Nexus 6p and Nexus 5x also have the same USB-C v2.0 so my question is, why do the Nexus phones charge faster? I believe the Nexus 6p used a 5v/3A charger versus the 5v/2A OnePlus2 charger.
With this in mind, would the OnePlus2 charge faster if we were to use a 5v/3A charger? Since it's using the same USB-C v2.0 standard?
Thanks

I am NOT responsible for destroyed devices, damaged batteries or Arctic Ozone Hole.
Please do some research if you have any concerns about using fast charging.
I managed to get my Nexus 5 charging at 1850mAh on Quick Charge 3.0 charger!
In theory, Nexus 5 can support Quick Charge 2.0, because it uses the Snapdragon 800 chipset,
but it uses a Texas Instruments BQ24192 chip for battery charging and power path management,
which does not work with Qualcomm Quick Charge. According to AnandTech ( Google Nexus 5 Reviewhttp://www.anandtech.com/show/7517/g...exus-5-review/3 ),
the Nexus 5 should automatically restrict charging rates to a maximum of 1500mA.
Quick Charge - fast charging technology
Qualcomm Quick Charge 1.0 is able to charge up to 40% faster than conventional charging (Max Power 10W)
Quick Charge 2.0, increasing the charge time advantage up to 75% (Max Power 18W)
Quick Charge 3.0 is designed to charge twice as fast as Quick Charge 1.0 and to be 38 percent more efficient than Quick Charge 2.0 (Max Power 18W)
Qualcomm Quick Charge 3.0 vs 2.0 vs 1.0
Qualcomm Quick vs Nexus 5 - the first 30 minutes of charge
Charging from your laptop or computer
SPECS
LG Nexus 5 D821 32GB ([email protected],65GHz)
Stock ROM 6.0.1 MMB29M + ElementalX 6.07 Kernel (Fast Charge Enable)
Anker PowerPort+ 1 with Quick Charge 3.0
RAVPower Portable Charger 20100mAh with Quick Charge 2.0
Anker Premium Micro USB Cables in Assorted Lengths (3ft, 6ft, 1ft)
PortaPow V2 USB Power Monitor + Ampere App
Original LG Nexus 5 charger and USB cable
Original OnePlus One charger and USB cable
Please note that I bought my Nexus 5 in November 2013 but I replaced the battery with a new one.
The maximum charging rates was 1850mAh - reading from PortaPow V2 (1530mAh - reading from Ampere app).
Tests
1. Nexus 5 Full Charge Time = 1h 20min 43sec
2. Nexus 5 Charge Time - 5% step (minutes)
3. Nexus 5 Charge Level - every 5 minutes (%)
4. Battery Charging Time Comparison (3A Charger)
I'm going to do some more tests soon.
5. Anker Quick Charge 3.0 charge + USB Cables (Nexus 5, OnePlus One, Anker, RAVPower ) vs Amps
6. Best cable from Test 4 + Chargers (Anker Quick Charge 3.0 charger, RAVPower Quick Charge 2.0/2.4A power bank, OnePlus One charger, Nexus 5 charger) vs Amps
7. RAVPower power bank USB Type-C (3A) output - I need to buy a USB-C to Micro-USB cable
Conclusion
The Nexus 5 was released more than 2 years ago (October 2013) and we can use it for everything!
We can overclock it, shot 4K videos, play H265 movies, create VR headset for PC gaming, run Window 7 or boot Windows 10.
Now you can fast-charge the battery. The Nexus 5 is a Quick Charge 1.0 device, but provides the same charging speed
as the Samsung Galaxy S6 that supports Adaptive fast charging or Quick Charge 2.0.
The Nexus 5 is a simply unblieveable phone!

Whoa, that's great news, mine tops 1500mAh with simple Asus 2A charger. It's not consistent though. Sometimes works, sometimes tops 1A. Couldn't figure out what stands behind that.
Says "fast charging" on home screen as well. Using Cataclysm + EX Kernel. Here's some more info on reddit.

The max. charging current was 1850mAh!

I know Uber kernel has a setting to choose max charge current, and it goes up to 1900mA. Tried it a few days ago but as i dirty flashed kernel, my phone was buggy as f*ck and i returned to ElementalX lol

I guess it is awesome.
But can it be harmful to the power controller chip...?

Must be the same current - 1850mA (EX) is almost 1900mA (Uber), I don't think you can get more.
Two years ago we charged the Nexus 5 for 2h 32min, now we can do it in 1h 20min - increasing the charge time 47% faster!

Yay, this will really ruin battery cycle life.

This is on stock 6.0.1 locked bootloader, no root. I plugged it into my Moto X turbo charger that has 3 different charge levels.

You just proved that it doesn't, with a qc 3.0 charger it only charged at 10 watts(volts*amps), that qc 1.0 spec.
If it would support qc 2.0 it would switch to 9v and even 12v during charging but it doesn't.
The reason anandtech showed 2.5 hours to charge is because they use oem chargers to charge the phones, think it was rated at around 1 amp. Switch to a high quality 2 amp one and it fixes the problem, my blackberry 1.8a charger does the job as quickly as your qc 3.0 charger.

It's true - the Nexus 5 is a QC 1.0 device, but it provides the same charging speed as the Galaxy S6 that supports Adaptive fast charging or Quick Charge 2.0 (see Test 4).
Ok, the battery capacity is lower 2550mAh vs 2300mAh, but the charging time is still really impressive for a 2 years old smartophone.
BTW, OnePlus One supports QC 2.0 (can switch over 5V - tested!)

Using a $3 blackberry folding blade charger I get 1800mah charge rates. No quick charge charger needed.

Just something to consider, a regular Nexus 5 is charged at about 900mA up to 1A current ( measured from my DIY power supply ). If you double the current, you also increase the power dissipation of the charging circuit by 4x. Sooner or later the whole device will fail.

No one here is forcing 2 amps into the phone with some hack, its pulling it by itself, meaning its capable of pulling that much current.

I managed to get my Nexus 5 charging at 1850mAh on Quick Charge 3.0 charger!
In theory, Nexus 5 can support Quick Charge 2.0, because it uses the Snapdragon 800 chipset,
but it uses a Texas Instruments BQ24192 chip for battery charging and power path management,
which does not work with Qualcomm Quick Charge. According to AnandTech ( Google Nexus 5 Reviewhttp://www.anandtech.com/show/7517/g...exus-5-review/3 ),
the Nexus 5 should automatically restrict charging rates to a maximum of 1500mA.
Quick Charge - fast charging technology
Qualcomm Quick Charge 1.0 is able to charge up to 40% faster than conventional charging (Max Power 10W)
Quick Charge 2.0, increasing the charge time advantage up to 75% (Max Power 18W)
Quick Charge 3.0 is designed to charge twice as fast as Quick Charge 1.0 and to be 38 percent more efficient than Quick Charge 2.0 (Max Power 18W)

Conclusion
The Nexus 5 was released more than 2 years ago (October 2013) and we can use it for everything!
We can overclock it, shot 4K videos, play H265 movies, create VR headset for PC gaming, run Window 7 or boot Windows 10.
Now you can fast-charge the battery. The Nexus 5 is a Quick Charge 1.0 device, but provides the same charging speed
as the Samsung Galaxy S6 that supports Adaptive fast charging or Quick Charge 2.0.
The Nexus 5 is a simply unblieveable phone!

You can use QuickCharge 3.0 charger but the Snapdragon 810 supports up to QuickCharge 2.0.
https://www.qualcomm.com/products/snapdragon/processors/810
So, you will be limited to 2.0 "speed".

i used SONY CP-AD2 charger rated at 2.1A. it charged at 1.31A according to ampere app. but it fully charged from 4% to 100% in 58 minutes. the best charging time i have ever got.

Note7 Supports 25W USB-C Fast Charging - 50% in 30 minutes

The wall charger that comes with the Note7 is different than Samsung's previous adaptive chargers.
Here's mine from my Note5 which is the same used with the S7-series

Here's the one from the Note7
And this is from Samsung's website. The terminology under fast charging is a bit muddled. I take it to mean that the charging tech Samsung's using in the Note7 is proprietary and if you use the charger with other USB-C or legacy Samsung devices it drops down to standard 2A charging like the previous adaptive charger.
Fast Charging
With new 25W USB-C Fast Charge technology, your battery can go from zero to up to 50% in about 30 minutes, so you can spend less time connected to an outlet. The 25W USB-C Fast Charge wall charger will charge the Galaxy Note7 and other USB-C devices without the Fast Charging feature as well, with up to a 2 Amp charging rate.
Rapid Charging
The Samsung Fast Charge Wall Charger plugs into any standard wall outlet via the included AC adapter. This Samsung charger has a standard output of 2 Amp to give your phone power at a much faster rate than your typical 1 Amp or 700mAh charger.
Flexibility
The Samsung Wall Charger also comes with a detachable USB to USB-C cable, which allows you to charge your phone from the USB port on your computer or other USB power source if you aren’t near a wall outlet. You can sync and transfer files with your Galaxy or any other smartphone using the USB-C cable.

This has been my confusing question. I assumed they would give it the more QC3 type rapid charge of some sort but wasn't sure. Glad its able to. I never use cabled charge but when I do, its because I need it stat. The more "stat" the better in that example.

This might be a thread hijack (if so, I can make a new thread), but anyone know if I'll get rapid charging if I were to plug the phone into my computer's USB 3.1 Type C port? (desktop PC)

Unless your computer can pump out 12v2.1a ( hint: it likely can't) then no.

Hard to say. I know the computer supports USB Power Delivery 2.0 through that port (using an onboard Intel USB 3.1 controller), but apparently the phone would need to support that as well (and I don't know what profiles of USB Power Delivery the controller supports).

I'm guessing neither because Samsung didn't use Qualcomm's Quick Charge feature on the S7-series. Samsung's Adaptive Fast Charging seems to be proprietary and is used on both Exynos and Snapdragon phones. Hence the terminology in the product description for the adapter that says "The 25W USB-C Fast Charge wall charger will charge the Galaxy Note7 and other USB-C devices without the Fast Charging feature as well, with up to a 2 Amp charging rate." I take that to mean that Samsung's charger and cable aren't USB-C spec compliant and won't work beyond the standard 2A output with other devices including those using USB-C. Once the phone's out I'm sure there will be lots of threads/posts discussing what Samsung's interpretation of USB-C really is.

Wait a minute...25W charging rate, even with a middling 75% transfer efficiency, should charge the battery by 50% in 20 minutes. And at 75% eff (a good charger would be in the 80s), it would make the phone pretty hot, as it would be dissipating 6W in waste heat. That's twice the power of the Snapdragon running full tilt. I'll be interested to see what th real rate is.

The phone is NOT going to charge at 12V/2.1A/25W. Samsung is likely just "future-proofing" chargers for a little while or making them compatible with larger devices that need more power. Nothing new in regards to the Note7's charging capability.

Nor did mine.

I'd like to know if anyone has tested a Samsung 25W charger with the Note 7. The fact that they included a 15W charger speaks to the contrary, but it's currently an unknown.

The Note7 is listed as a supported device if you pull up the 25watt charger on Samsung's website

Well for sure it doesn't support USB PD @ 29 W from the Macbook USB-C charger. Seems to only get 5-10 W out of it, and same from the Macbook itself.

Where did the 12V/2.1A/25.2W charger come from?
Mine came with a 5V/2A and 9V/1.67A charger.
Edit - so I did some research online. That charger was meant for the Galaxy Tab Pro S? Which functions more like a Windows 10 laptop than a tablet.
Are you sure the EP-TA300 is compatible with the Exynos Note 7?

A Chinese Website Chongdiantou has proven that both the Snapdragon 820 and the Exynos 8890 variants of Note 7 support USB Type-C Power Delivery and can handle up to 25W of power input.
I am not allowed to post outside links. You can google "实测：这几款USB PD充电器支持三星Note7快充-充电头网" and see the readings on the power monitor.

Hmmm... Dont know if I'd plug my Not 7 into that new Super fast charger as of now. It may charge it much faster but with a 50/50 chance of it exploding every charge is too risky for me.

I have these two. One is much larger then the stock Note 7 charger. Note 7 stock on the left and the fat boy on the right. Both came with USB-C cables.
Is the fat one on the right safe to use with the Note 7?

S20 doesn't charge from USB-PD power supply

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.
https://www.sammobile.com/news/samsung-galaxy-s20-charging-issues-troubling-some-owners/

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.

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.

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.
