Question about weird fast charge Galaxy S8+

I have 4 chargers on hand listed below...
1. Original Samsung Adaptive USB Charger
2. Anker PowerCore+ 10050+ QC 2.0 Charger
3. Anker PowerCore 10000
4. Pleson Fast Wireless Charger
Now my question is why is my S8+ charging similarly with all these chargers? Example @ 30%.... The Adaptive charger says 1 hr 9 min (reads fast charge), the Anker 10050+ says 1 hr 25 min (doesn't read fast charge), The Anker PowerCore 10000 says 1 hr 25 min (Not a fast charger), and the Pleson Fast Wireless Charger says 1 hr 44 min. I am confused.

Because only 1st one is actually fast charging your phone.
You should try 2 and 4 with original cable. If you have qualcomm version of s8 shold work

I'd echo the original cable and the wall plug that came with the device. Retry all 4 of these with the original cable and the wall plug.

Well I don't know if the Anker products are charging oddly because one is QC 2.0 and the other isn't, yet both have same 59 min charge time. So I question is the Samsung Adaptive charger is charging slow or fast? Here are some pics of the remaining charge with original black USB Cable.

From my experience, Samsung Devices don't really play nice with qc certified devices thanks to Sammy doing their own thing. What you are seeing is what made me buy Samsung's power kit.

I have no issues with my chargers, use stock charger blk, use sammy wireless charge pad with aftermarket cable and s7e wall plug charger and no issues. Still get fast charge. I even have a portable 10000mah sammy pack and use my gopro usb-c cable n gef fast charge.

Do you mean this one....

Had similar problem. All my Anker QC2.0 doesn't fast charge my S8 while 3.0 does. got them both refunded while they are investigating.

Strange
does that mean S8 has QC 3.0

Yes I am in talks with Anker as well, seeing what they find out about my QC 2.0 Anker charger.

They sent me another QC 2.0 car charger, and it did not fast charge. I am going to try Berkin USB-PD car charger and see how it goes.

Estimated time. Don't expect them to always show exactly the time.
I have QC 2.0 and 3.0 chargers and they all "fast charge" but I don't expect what the estimated time show to fully charge be accurate or else they wouldn't say estimate.

Compared to my s7edge this s8+ charges a lot slower. The s7e would fast charge and wirelessly fast charge from any third party wireless pads/adapters.
The s8+ is finicky about what activates fast charge (especially wireless) and even while in fast charge it does not charge as fast as s7.
My guess is samsung slowed the charging down to help with battery degradation.

I found a weird thing last night when I set my phone to charge at 2 AM with about 7% battery just to wake up around 6 AM and it being at 86% charged. That was a long time, I don't know what's going on. Either the phone isn't quick wireless charging or the Pleson Fast Wireless pad I have sucks.

So, I've seen this behavior too. If you see the charge stuck, unplug the cable and plug it back in. I'm not sure why, but that fixes the issue immediately.

Are you guys charging in a warm room? S8 will stop charging if the battery exceeds a certain temperature. Samsung really went overboard with battery safety after the Note 7.

Is Power Delivery Supported?

Does this model support power delivery like the Pro model? If so has anyone tested how many watts it pulls from a power delivery charger? Oneplus states the pro model supports 5V/3A power delivery which I believe is 15watts.

Pro 30W
Non Pro 20W

These specs are for Oneplus's proprietary warp charging which is separate from the power delivery standard.

Without that it's unreal slow, maybe 1A

you are uninformed. in addition to Warp, the 7p supports PD upto 3a with screen off. Android police confirmed this in their review.
OP is asking if 7 also supports this.

I have not measured charging speeds, etc. but I have a bunch of official Google PD bricks here for my 2XL and my OP7 charges just as fast, if not faster, than my Pixel. Just anecdotal but I was happy with charging performance.

I've charged my OnePlus 7 from 14% to 100% in about 1h and 15min. I call that really fast charging.

Like I sad, it will be 1A, maybe for the first 50% 1.5A, because with 3A a lot will not pay the extra bucks for Dash charger.
Pro: 5V/6A - 3A
Non-Pro: 5V/4A - 3A? No way... with luck maybe 2A
I will get my OP7 next week and I can test it but I'm sure you will get up to 1.5A

I've charged it with a power bank from Huawei, with fast charge and it charged pretty quick. I haven't look at the time it took, but next time I will.

So you are saying:
OP7 Pro supports USB 3.1, USB PD protocol to 3A, and Warp-protocol to 6A
OP7 supports USB 3.1, Dash-protocol to 4A, but NOT USB-PD?
Please do test it- to confirm, you must have 1. screen off 2. a USB power meter that can measure the draw (or an app that can record the draw while the screen is off- viewing current while in app will not work since it only works with screen off.
There seems to be a lot of people who don't understand what USB-PD is. Of course, if you use a normal USB charger that is neither Dash/Warp nor USB PD, it will not draw more than 1.5A.

Dude, USB-PD means USB Power Delivery. How somebody can not understand what this mean?
Oppo slow it down to sell VOOC/Dash charger (and cable) in the kernel, like on the OnePlus devices before.
When the OP7 support 3A, with 5V, you will get 15W, which is almost QC 3.0, so you can get 5 charger and any cable you want for the same price as a Dash charger. There is no way!

So I've tried today charging with my power bank, a HUAWEI 10000mAh QuickCharge power bank, from 1% to 100% and it took about 2h and 30min. From 15% I think it would take about 2h to charge. Power bank fast charging is rated at 9V 2A 18W. With Ampere it was showing to chager at about 1.3-1.4A. I would say it's pretty ok, it's not as fast as with the original charger, but it's ok.

That is not a USB-PD bank. It'll charge at 1.5A tops with that. Our phones can't do QuickCharge.
Do the same test if you can, but use a USB-PD charger and screen off.
This thread is about getting a confirmation that it can regulate with USB-PD upto 3A when the screen is off. Our phones will not support QuickCharge or any other proprietary protocol.
We know It does Dash/Warp, regular USB upto 1.5A, and now we want to know if it does USB PD.
---------- Post added at 09:16 AM ---------- Previous post was at 09:04 AM ----------
So I caved and finally tested it myself.
Yes, the regular OnePlus 7 does support USB-PD 5v upto 3A with the screen off. With the screen on, I could get 1.94A
I used an Essential PH-1 included charger, which is a USB-PD charger that can do 5V and 9V upto 3A. I went from 60% to 70% in 8 minutes, and used the logkit to capture the current. While on, I was getting a consistent 1.94A, which is higher than a regular USB charger which usually peaks around 1.4-1.5A. With the screen off, I kept the logkit going, and you can see the average is well above 2A (again, this is average- I had the screen on for a while before an after, which is why the average isn't 3A). It's also worth noting this was only from 60-70%.
So yes, like the OP7 Pro, the OP7 also supports USB-PD up to 3A with the screen off, and upto 2A with the screen on, much faster than a regular USB Charge, and ALMOST on-par with Dash Charging with screen off.
So hopefully this puts this thread to rest, and you can feel confident buying a USB-PD brick, and those that doubted it have learned that OnePlus didn't skimp on the USB controller on the regular OP7.
From the graph, you can see the flat line at -3 when the screen was off, and how it bounces "up" to -1.7 when it's on.

Can confirm, used my USB PD charger while away last week. Charge from 5ish% to full was around 2 hours. Much quicker than the old standard Microsoft USB C charger I use at home.
Charge time with PD was similar to that with my old mate 20 pro which showed 'fast charging' to indicate PD being used.

MI 9T PRO 30W Charger experiment

Was searching about chargers that should work with the phone a little while back and there was allot of mixed and confusing talks about what charger to get ( most tests where done with Amper app, that does not show s*it), allot of people where recommending the sonic charger as the only/best option for 27W charging.
Not being available in my region, got myself a Baseus 30w charger ( the one with USB + type-C PD port ) + a USB-C power reader.
Phone is on latest MIUI EU version 11 ( android 10)
Those are the findings:
The phone will charge Turbo using the USB port and go up to 30 W
The phone will charge also up to 30W using the type-C port, but the Turbo is not displayed.
p.s. ignore the total mA charged reading. At first my usb power reader had a bug or something. it was reading 0.01A at 9V, Started working fine after a replug. reading 3 - 3.5A at 9v
The first photo is using type-C
The second photo is using the USB port. It only shows 12W because was just plugged in. But will go to 9V 3A in a few seconds.

Wait so does this mean the 30w charger works?

Is that the Baseus 30W PD Quick Charger you bought?
Are you getting the full turbo charge using the Baseus USB Type C cable?
Or
Do you need to use the USB Type C cable that came with the phone?
Or
Purchase another compatible cable?
I know, questions, questions, questions..
Was contemplating buying OnePlus 7T or Realme X2 Pro, but reluctant after hearing about the display issues [red tint, green tint, uniformity fault] that are affecting them.. Previously had the OnePlus 6T McLaren but didn't have great mobile reception..
Think OxygenOS and MUIU better forks of Android.
Think am set on the Mi 9T Pro UK/Global edition, just waiting to see what Blacl Friday bring from EGlobal.
Would buy direct from Xiaomi if had 256GB version. But they doing what OnePlus doing and preventing purchase. Stinks, because you get 2 year warranty as opposed to 1 year if buy direct. [OnePlus & Xiaomi do this].

The charger works 22% to 96% in 52 minutes ( 22% to 77% in 30 minutes as seen in the picture above, had to leave so i did not let it reach 100%) it charged with 30W till 80%
It does not display turbo with usb-c to usb-c. but it charges with 30W, don't think the baseus cable has anything to do with it. was just the cheapest 3A rated cable i could find, the charged does not come with a cable
Also did not test other cable for USB to type-c. had the original xiaomi one in hand. but again. don't think it matters. any 3A cable should be good.
charger model is BS-EU905

UK 30W Charger for Mi 9T Pro
Am nearly all settled on decided to get the Mi 9t Pro but will hold fire till see what Black Friday discounts there are.
I can manage to get the 6GB/128GB with EU plug from CSMobiles for under £305 delivered. But would prefer the 8GB/256GB model.
If I do get, then will be purchasing the 'Baseus 30W PD Quick Charger UK Adapter' -

don't think the 256gb will ever be sold outside Asia. I'm fine with the 6/128 model

24hr dispatch <- recommended to buy from EGlobal only if this is displayed
**Read some threads that state its EU variant with Band 20-800MHZ - Am with Vodafone and is a required Band for 4G **
Will soon find out..

well . i stand corrected. it seems there is a global version with 8 ram and 256 storage when i got my phone there was none. It's a good phone. so enjoy

Is baseus company even safe to use?, Since it's always a little unsafe to use 3rd party chargers.

as long as they are using the standard charging protocols, should be fine. At the end of the day only difference is the branding. they are all made in china after all...

Hey can you tell me the exact timing.
I mean from 1% to 100% in how much time and also let me know how much does it charge in first 30mins and 1 hr mark. (please try to make it from 0 to 2% .
With my 27W sonic charger it takes
0-57% in 30mins and
0-93% in 60mins and
To full charge it takes 1Hr 18mins
All from 0 to 100

i usually don't let my phone go under 20%, ill post if ill try it from 0 to 100

I bought this one: Fast Charger 30W MacBook Pro Charger with Type-C Cable Power Supply Fire-Proof PD 4.0 for Samsung Phone, The New MacBook Air/iPad Pro/iPhone QC4.0 (30W +Cable) from amazon, and at that time I paid $9.99
Can't say the amount of Amps but it charged my phone from 50% to 90% in 30 minutes! The only problem I had was the provided usb-c cable charges my Mi9T only in one direction (weird)

here is more info using the USB normal port and the original xiaomi cable, phone display's turbo charging, the USB power meter shows 25W going in the phone ( a little slower than PD):
9% to 30% in 10 minutes
30 to 40% in 5 minutes ( charging rate is around 20W)
9% to 100% 1:19:32
will repeat the test again once my 5A cable comes, and also using type-c PD

A lot of things are made in China, doesn't mean they are all the same quality lol. Factories make stuff according to the specs given to them, if they were asked to make poor quality items, they will. If you give them the plans and contract them to make A grade stuff, they will too.

That's a bit slow as my 27W sonic charger charges from 1 to 100% in 1Hr 15mins.

Does it really make a large difference compared using a 27W charger?
I don't trust Ampere and the numbers all the time.

After MIUI 11 update my deice shows quick charging for the Apple Macbook Air 30W charger. It wasn't showing for MIUI 10.

Will any 65W charger work for Super VOOC charging or does it have to be the specific Oppo charger? Anyone have any experience? I rather leave the charger it comes with new in the box for selling purposes and would pick one up on Amazon if it works with a regular 65w charger

Yeah I found it is proprietary for Super VOOC. Although 65W, it needs to deliver it at 6 amps & 10 volts to get the super fast charging. No on the market charger has that option (even smart 65w chargers) to deliver the power at that rate... if I keep the phone long enough, I'll just get one from aliexpress.

You can buy oneplus chardger, i try with old (op5) oppo show vooc chardge. And with new (op 7t pro) chardger i have super vooc. Its the same.

Oneplus Warp charger 30T charges at VOOC, not super VOOC, for me

hello
have a nice day

Would the OnePlus Warp Charge 65 Power Adapter (https://www.oneplus.com/uk/product/oneplus-warp-charge-65-power-adapter) be apple to charge an Oppo Find X2 Pro with the same speed as the original charger?

15-18w charger from samsung charges fast too without melting the battery like 65w.

Question Charging speed

So... Phone is supposed to charge at 45W but, from what I've read, this is not really true...
I do not have the original 45W Samsung charger but a 3rd party multiport 90W charger, with 2 PD usb C and one A port.
Till yesterday I was using a standard usb C to C cable and phone would display "fast charging" with an estimate of 1h from 15% to 100%. Not really a good performance I'd say. Today I bought a certified 100W cable with a display showing charging speed (usb C to C). With this cable two things change: phone displays "fast charging 2.0" and charging speed has slightly improved: less than 1h from 12% to 100%. Still not fast enough for a 45W charging... And as a metter of fact after 5 minutes the display on the cable stops at 28W...
This matches with lots of articles that complain for the same problem...
I also have a Xiaomi 12 Pro with dedicated 120W charger + dedicated usb C to A cable (charger has A). I'm saying dedicated, because with any other cable (standard usb C to A or even the above 100W usb C to C with adapter) the Xiaomi displays "turbo charging" while with original dedicated Xiaomi cable it displays "120W max" and is indeed blazing fast: 15 min for a full charge!!!
What is strange is that if I use the Xiaomi 120W charger with dedicated cable on the s22 ultra, phone displays only "fast charging" without the "2.0".
Now... I'm not trying to compare charging speed of s22 ultra to 12 Pro: Xiaomi can achieve such a speed because the phones have two separated batteries that charge simultaneously, thanks to a power splitter that takes the 120W input and splits it into two 60W, one for each battery.
What I'd like to know is what's going on with the s22 ultra. I understand that a basic cable is not enough to deliver 45W, reason why I bought a better cable, yet I was expecting a big improvement, while it improved charging speed of less than 10 minutes. And as a matter of fact I've never seen 45W on the cable display. Maybe I need an original Samsung 45W charger instead of a 3rd party one?

Search the forum, there is a few topics regarding 45w charging... I have a 65w charger and 5a cable and the charger has all the necessary properties/charging formats needed to fast charge 2.0 the samsung, but it doesn't. i don't even get the fast charge 2.0 notification....In the end the difference between the 25w and 45w is very slim....will be a waste of money to purchase the 45w samsung charger....check the other discussion.....my charger takes basically an hour from 10-100%...it's good enough for now

Well good enough if not compared to the blazing fast xiaomi's 120w charge

Most of the time, it's only several minutes charging time difference when I have a "Super fast charging" charger or a "Super fast charging 2.0" charger connected. 45W charging seems to be over hyped by Samsung and it's not using full power to charge all the time.

I have the original new 45W charger and the phone charges from ~ 0% to 50% in approximately 20 minutes as advertised. It is faster by around 22% in comparison to the 25W fast charger between 0-50% state of charge. Afterwards they both charge in almost same way with the 45W charger being max 10 minutes faster by reaching 100%. You need a PD & PPS charger. There are only some 3rd party ones that manage to do same as checked by androidpolice:

My charger is compatible with FC 2.0 but as I said it depends on the cable. Real problem is that 10 mins faster between 25W and 45W is a real joke. Given this phones is energy hungry then... With the Xiaomi 12 Pro I don't even care: 5 mins and I get 30% of charge, although you need proprietary charger and cable

It depends on what you want. For example I am perfectly happy with my 25W charger which comes rarely in use because of me charging wirelessly and without fast charging over the night but I bought the 45W one to have the possibility to get that extra speed between 0 and 50, and my girlfriend gets my old 25W one for her base S22. Samsung has a different approach to fast charging and for me 120W on Xiaomi or 150W on Oppo/OnePlus is something I do not need although I am curious why Samsung did not make the same move yet. Just split the cells in two or three, give each cell a maximum of 25W and boom, you're in the mix and nobody will complain.
On the other hand they lied to us about last gen 45W charger which was useless so it is fair to say that their battery & charging department is almost on the same bad level as the Exynos software team if not actually worse than them

It depends on what you want. For example I am perfectly happy with my 25W charger which comes rarely in use because of me charging wirelessly and without fast charging over the night but I bought the 45W one to have the possibility to get that extra speed between 0 and 50, and my girlfriend gets my old 25W one for her base S22.

2 cells is exactly what Xiaomi does
Reg Samsung, that's my point: they indeed lie, it's not a 45W phone. Full stop.

I have two Super Fast Samsung 25 watt chargers. One for my S22U and One for my Tab S7+ and both can charge in under an hour. 45 watt chargeers just wasting your money, and extra wear on the battery for a tiny bit of improvement. Not worth it to me.
