Resolved: SM-N986U max 15W charging - Samsung Galaxy Note 20 Ultra Questions & Answers

Using the charger that came with the phone, the maximum charging I get is 15W. I tried a different cable and bought a different PPS charger, but still my charging maxes out at 15W. I was expecting to see 25W.
Has anyone else seen this issue? I have confirmed that both fast and super fast charging options are enabled. It does say that it is super fast charging when plugged in.
Thanks.

measured how?

Using one of the USB Digital Testers that is in the shape of a cross and is sold on Amazon.
I believe I figured out the issue. My phone was at 80% or something high when I measured the charging rate. So I think it was being throttled. I tried it again when the battery was much lower, and it was just about 25W.

Battery charging, 500mah (slow) or 1000mah (fast) any difference in performance?

I've noticed that charging with 500mah charger, charges the battery MUCH slower than a 1000mah (1amp) charger, which charges really fast. I'll need to time it, but I'm thinking the 1000mah charger charges the stock battery in less than 2 hours, where as the 500mah charger takes many hours, I usually let it charge overnight.
My question is, is there any performance gain to slow charging vs fast charging? ie: slow charging giving a deeper charge, vs fast charging?
any opinions?
i use a 2amp charger i had already that fully charges the O3D in around half an hour/45 mins. get the same runtime whether i use that or the stock charger.

Any chance of a link to this charger, I'd really like that sort of charging speed.

My guess would be anything that would charge an iPad... those require like 2.1amp, so that would be a 2amp usb charger.... I've seen 2.1amp home chargers, car chargers, etc... all because of the ipad I'm guessing.
Its not that simple. Any device that uses USB for charging can only pull 500ma, that's a universal agreement. To get around this each manufacturer uses a method of "informing" their device that it is connected to a charger that can supply more current (HTC shorts the data leads in the supplied charger I don't know what LG does). I have a 1amp car charger but it still only gives 500ma but the genuine LG charger gives an amp because the phone "knows" it can supply more.
I'm going to stick a test meter into my LG chargers over the holidays to see how the data leads are connected.

The charger i have is a noname brand. I bought it from walmart for 6 quid. It also came with a 2amp car charger and a micro usb cable.
Micro usb cables are not standardised like that. Ive never heard of such a thing at all. As far as i know most phones will "fast charge" if they dont detect a data connection and dump as much current as they can into the battery so you can pretty much present them with whatever current you like and the charge time will just get faster. There is probably a hardware limit to that somewhere in the charge circuit but i dont know what the limit is. 2amps is the highest power usb charger ive seen but its not exactly aomething i regularly keep an eye out for.

Slow charging is always better as this will allow the optimal number of battery cycles before the battery's capacity will start to degrade.
So if you only ever slow charge then your battery will have a longer life cycle.

[Q] Need someone with hp touchpad charger to confirm

So, the charger for my old touchpad has the longest cord, and twist to lock is great..
But I've noticed that my phones all charge ridiculously fast on that charger (40 minutes from dead to 100% in most cases) and I'm wondering if maybe it's being detected as a quick charge plug? On stock, I didn't get the slow charging notification, and I don't get it on Viper or Bad Boyz either.
Does anyone know what it takes to NOT trigger the notification? Is it a certain pin out? I'd assume not, since you can use any cable with the Qualcomm wall wart.. Is it a specific voltage? Amperage? I know this charger is 2A, 3.5V and from what I can find on the Qualcomm specs is that a charger needs to be capable of 1.5A, 5V for quick charge certification, which puts my charger still 1.5V shy.
So why does my m9 charge to full in about 55 minutes, vs a few hours on stock, and NOT trigger slow charge notification when it's (afaik) not quick charge?
Can someone else with a stock touchpad charger that gets the slow charge notification test this out for me? If it turns out this is basically an uncertified quick charger purely by virtue of coming out before QC, that would give us an option for QC on the cheap!
So far the best I can find is that the reason this charger does so well is because the touchpad is a power hungry beast and needs a beefy charger, more so than regular tablets. I guess that explains it. It's putting out more than a phone charger usually would, which is why it isn't triggering the slow charging prompt
My daughter "inherited" my touchpad, but I believe its charger was 2 amps
Sent from Tapatalk on either my HTC One M9 or Tab4 10.1, it kinda depends
My touchpads wall wart puts out 5.1 volts and 2.1 amps, with it's quality cable. It is the fastest charger I have out of the dozens I have tried. Most put out less current/amps and that is why it can charge so fast my comparison. But know that one bad USB cable can make the fastest charger slow. I used the galaxy charging app to test my cables on it, and found some of my USB cables would only do 400ma no matter which charger they were in, so I threw out or marked all those so I wouldn't use them for fast charges.

Using a 2A charger

Anyome using a 2A charger instead of a turbo charger?
Like a samsung 2A charger
Or a 2A power bank?
Any issues?
Because 1150 mah is too slow
I was also wondering this.I tried it with my 2,4a ipad charger once and it was charging twice as fast, but i dont know if this is good for the phone. Using the normal charger again to be sure.
With normal 1.2A charger, it takes almost 3+ hours for my phone to fully charge. I used my Galaxy Note 10 charger which is 2A and it got charged in 2 hours. I read it in the forums that even with 2A charger, we cant take the advantage of turbo charging as it will need a charger of 2.4A.
I dont know how 0.4A will make a difference but still, my knowledge is limited in this case and wouldnt want to comment on it.
The charger has to be Qualcomm QC 2.0 certified (that's a specification) to take advantage of the turbo charge mode. The amps put out by the charger is kind of secondary in this situation as the charger and phone both need to be "talking on the same page" i.e. QC 2.0
At that point (charger is QC 2.0) the special circuitry kicks in and goes into turbo mode. So its a little more involved than just throwing more amps at the phone. If you google Qualcomm QC 2.0 specification then it will give you a better idea of what it is all about.

Turbo charging steps up to 9v and 12v depending on what wattage the phone can handle.
I think our phones are 15w and the Style is 20w or so.
I can't get my phone to charge faster with a 2amp charger though, only my turbo charger.
I used digitech 2.4amp charge ans works like a charm superb....
It isn't causing any issues? Like battery degradation?
Sent from my XT1562 using Tapatalk
I've been using my Moto turbo charger every night for a couple weeks now and haven't noticed any issues. The phone doesn't seem to let the battery get over 35'C when its charging, so I don't imagine it'll damage the battery.
Think I may get a car charger soon, sometimes I forget to charge at night so it'd be cool to get a full charge on the drive in.
Battery will very likely not last as long when doing fast charging always compared to "normal" charges
Any fact to back that claim?
Im using a Belkin 2.1A charger, no problems whatsoever.
So what's conclusion is it safe to use 2a charger without doing damage to battery

I'm using a 3a charger and it's fine
You can't harm a battery with a higher amperage output charger. The phone will only consume what it is able to. If the voltage was higher (excluding quick charge adapters) then yes that will do damage, but that's a strange situation as no charger should do that unless it's quick charge.
That being said, on hand I do have a feeling that quick charge can actually do long term damage if used a lot but on the other hand, it seems to limit the maximum temperature to around 38'C. Above 40'C can cause irreversible damage to the cell. I'm using a car charger now and when the phone is in use, it gets up to around 38 or 39 and it cuts back on the charging current.
Interesting article explaining Qualcomm, fast charge, turbo charge using all the same technique under different names. They all use the same Qualcomm technique.

How fast is OP6 charging without dash rapid charger?

I have the Samsung Note 4. Like the OP6, it has a proprietary "quick charge" mode, but I find it will also charge quite fast when provided with a non-Quick Charge source such as a battery that can source several amps of current.
How fast does the OP6 charge without the Dash charger and cable? (in terms of amps drawn from source?)
Like it would take years like why would you want to know this, if you broke your charger buy another and look after it like. It's one of the main features of the phone and they don't talk about how fast it charges like
At work i use a QC3.0 charger for my OP6. Didn't notice a great difference to the DASH charger at home. Maybe DASH is a few minutes faster.
40% to 70% charge with QC3.0 is still insanely fast.
Stay on topic guys. OP asked a question, which could be answered with facts, rather than opinions and scenarios. In my regular car charger, I go from 22 to about 70 in 40 minutes, if I can recall correctly.

I'm not sure if you're serious or sarcastic, but In case of the former, here are a few reasons why someone might be interested in charging with other than the Dash Charger:
1) AFAIK, Dash is available in AC mains or 12V Car charger versions. I often use a 20K mAH Anker powerbank battery for charging. That is usually in situations where other power is not available, but a quick charge is needed. Huge current is available, but would the OP6 use it?
2) I use a compact travel charger that has 5 USB charging ports. Using a Dash charger would require carrying another charger (big, bulky, without retractable prongs), and occupying one (or more due to the shape) additional AC outlets.
3) I have a phone charger in my bedroom, at my desk, in my travel bag (both AC and Car style), and in my car. A quick check on Amazon seems to indicate that the Oneplus6 charger is several times more expensive than other "quick charge" chargers. Over multiple charger locations, the extra costs add up.
Using the word "like" so many times makes it difficult to understand the post.

I'm Irish, apology
I have a stockpile of fast chargers that used the weird Nexus standard (5V, 3A, non QC) and they're okay, and for overnight or at my desk at work that's plenty fast to get the job done. The phone shows them as "charging" and not "charging slowly."
I purchased a "Tinduqin oneplus5T charger" from Amazon that works and looks exactly the same as the original dash charger for about $20, but it seems to already be sold out.
If you don't use dash charger,you only can charge at 5v 1.5a,I have tested it with apple 45w pd charger,xiaomi qc3.0 and nexus 5v3a charger

It won't charge very fast because it doesn't use any on board quick charge it's all in the dash charging brick
I have a bunch quick chargers 3.0 at home. It takes a life time. I end up buying the dash charger. I still use the quick charger for over night charging
there must be some sort of software restrictions on oneplus6 since measures show that oneplus6 cannot be charged with more than 5V-1.5A.

Do you own the OP6? Do you have a USB power meter that could measure the charging current with and without the Dash charger and reply with the values?
On my Note 4, it charges at about 1.17A / 5 V when the screen is on, and the current goes up to 1.6A with the screen off. That is with either a QC2 Quick Charger or a battery power pack. The phone reports "quick charger connected" in both cases.
oneplus6 has 85% battery left, measured with usb voltmeter and original oneplus dash charger 5V-4A, it shows that oneplus6 is dawning 5V-1.3A and same thing is happening with other usb chargers capable to deliver over 5V-2A.
I guess oneplus6 should be discharged less than 50% or something in order to start receiving over 5V-3A

Is it possible to use a the original DASH-adapter but with another USB-C cable? I need a longer cable so I can use the phone whilwe charging.
OnePlus has a original cable for sale which is only 150cm Long.
My question is if I can buy any other manufacturers cable whish also support some sort of fast charging. I've heard for example that DASH-charging is the same charging model that Huawei P20 Pro uses, they just have different name. .
So, is there anyone here that has switched the OP original cable and charge it up with a cable from another manufacturer?
There has to be a solution to this. Me myself can't. be the only one that needs s longer cable.

That's normal. Phones pull the most amps when on low battery, then progressively less as they are charged.
Check how much it pulls on <40% and <80% respectively.
Well, I charged my Op6 with a no-name USB 3.0 charger yesterday (forgot my dash charger at home, I was by a friend) and from 3% to 100% it took about ~1 hour and 55 minutes.
Not that bad I guess. But I still prefer my dash charger
I'm using a huawei p20 pro charger atm. Phone states from 75 - 100 it will take 33 minutes. (prob a bit faster if I don't use the phone.
Here is a charging session with a Oneplus 2 charger without quick charge
Charging from 27% to 100% in 2 hrs, 40 min - avg. Charging speed: about 1000 mA/h
Hello,
I'm using this old thread since we're talking about the same thing.
Is there a kernel or rom for the OP6 that enables to draw as much current as possible form third party chargers? It's sad that it's stuck at 1.5A no matter the charger unless you use dash charger. 2A is already something, 3A would be awesome.
Of course only if this a software limit.

Question Difference in charging speed

Is there a difference in charging speed between an Anker Nano 3 and the official Pixel 30W charger? I bought the Nano but accubattery tells me it only charges at 17 watts while the P7P should go up to 23 watts. Should I return it and get an official Pixel charger? Or is it normal that it doesn't reach 23 watts? Adapative charging was off while charging.
Since Anker is a well known brand, I would test it another charger. It very well could just the device only pulling 17 watts at that moment. I have multiple Anker chargers, cables and hubs at work and home. I have never had a charger fail or come up short on the rapid charging.
I have Anker cables and I noticed they charge much slower than the cables that came with and are designated for these devices. Still faster than my cordless charger.
Thanks for the replies. I'm using the official Pixel cable. I think I will order a Pixel charger and see if there's a difference.
I am using an Anker Nano Pro (20w) with Anker cables and my P7P charges in just under 2 hours which is only a few minutes slower than the official 30W brick.
This is a good read https://www.androidauthority.com/google-pixel-7-charging-30w-3226058/
Thanks, that's interesting. I will let my battery deplete further and see if the wattage is higher when charging from a lower percentage like that article says.
I am sure i have read in the past the Pixel 6 Pro over the whole charge averages only 13W, if your reading is for the average and not peak wattage then maybe 17W is right
Keep in mind that maximum charge wattage will drop off if the phone is doing things at the same time. Just turning my screen on and looking at the AccuBattery charging screen takes between 1-2W and there are spikes beyond that as apps do things.
It's not worth buying expensive chargers to get the highest wattage possible as it's a negligible benefit since the average is going to be way lower than the peak anyway. Both my OnePlus 9 charger and my Anker charger seem to peak around 19.9 watts with the screen on and they both support USB PD PPS.
