Faster charging?

i recently bought the P900 (wifi version).
full charge will take around 5 hours, which in practice translates to 4 hours (i never get to 0% and charging from 90%\95% and on will be slowed down by the device anyway).
is there any way to speed up the charging?
like buying a 5.3V 3A charger. will the OEM cable be able to transfer the additional current?
could the device even take advantage from a 3A charger?
if so, can you recommend on any?
its important to me because i always use 100% brightness.

No. In the past mobile devices (mostly phones) shipped with cheap 500ma chargers and bumping up to higher amperage chargers would have an affect on charge time. Those days are gone as charging efficiency of chargers and cost to produce have lead to included chargers being optimized for charging times. Charging circuitry in the devices is going to take what it's rated to take and no more, so once a charger is plugged into it that's rated the same as the device is designed to take there's little else that can be done to speed up charging.
Bottom line - the charger that came with the tablet if it's the official one (i.e. if you bought new, not used and someone included the wrong one) is optimized to charge the tablet at the fastest rate. Based upon the numbers you noted your charge times are not excessive, the tablet is designed to take around 2A and it won't take 3A even if the charger is rated for it.
If you want faster charging you need to sell your tablet and get a Snapdragon variant instead (LTE tablets from various carriers) or start practicing better battery management to reduce how depleted your tablet gets. For me that means not running at highest brightness unless I really need it and topping off the battery whenever I can. When I get really low and I have a reasonably long period that I can charge I'll sometimes shut the tablet completely down rather than put it to sleep so that charging is accomplished with near zero load on the battery.

oh, bummer.
well, i guess i would have to learn how to live with that.
TY for your reply.

im planning on buying a 2 port charger so i wont have to carry so many stuff with me,
how much slower the device will charge with a 5.0V charger?
should i look for a 2 port 5.3v charger? a normal device wont have troubles with that?

It's not the voltage it's the amps. If you want to charge two devices simultaneously as quickly as possible the power supply needs to be rated to output the wattage necessary to provide the amperage the devices will draw for maximum charge rate.
My recommendation is to find something capable of over 20 watts (2A x 5V = 20watts). I'd buy this for future Qualcomm quick charge use.

my question was how much slower the note pro will charge with a 5.0v 2A charger as opposed to the OEM one which is 5.3v 2A.
and if there is any problem to use a 5.3v charger with a normal smartphone.
charging the note pro is more important to me than my other devices.

Yes but you also noted that you want to buy a 2 port version and I'm saying that the voltage is only part of the equation. Unless you are already aware that you need one rated at 2A simultaneously (you didn't specify). I honestly never measured between the two, I do not worry about 5V vs 5.3V since the charging voltage of the lithium ion cells is under 5V anyway. AFAIK the current is more critical. Maybe someone else more knowledgeable in electrical engineering can chime in since I'm unsure how the charging circuit within the phone will step down the voltage from the charger to the battery. All I know is if one tops off regularly or charges overnight there's no night and day difference between the stock 5.3V charger and a 5V one so long as the aftermarket one is rated 2A or more.

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 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

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.

Question How do you get 25W charging?

I tried using two approved chargers. The Anker Nano II and official samsung 25W charger. Getting capped at 15W. Am I doing something wrong?

Same here, I don't think it'll ever go to 25W. One of those Samsung unfulfilled wishes? Am using the original 25W charger and DevCheck Pro readout shows oscillating wattage between 18.8-17.3(battery level ~35%) Maybe they could fix it w/OTA software?

I use this charger and the screen-on charging value goes up to 4 Amps (as reported by Accubattery) so I guess this is the perfect charger for 25W charging. Also in the specifications, the rating is mentioned; some are very near to 25W.
If you want to figure out the wattage use the simple formula W=V*I where W=wattage in watts, V=voltage in volts and I=current in amps.

Been using the very same EP-TA800 adapter, "25W" as Samsung misinterprets it because it only goes to 18W max or so: (started at 26%, second pic 45min later)

You are right, I can confirm also that the 25 watt charging is just gimmick.
When your phone are low battery (under 30%) you only get 25 watt of power pulled from your charger for a minute or so.
Then the continue charging speed are about 18 watt.
With AccuBattery pro app, after several various charging time, I get average of charging speed = 90% per hour
Usually I charge my battery from 20% to 85% in 44 minutes. With phone screen off about 30mins.

You can also check what charging levels you are supporting by going to Settings -> Battery and device care -> Battery -> More battery settings
Just a heads up for anyone not coming from the Z Flip 3, though, that Samsung reset the evolution of USB-C on the series. The Z Flip 3 launched with 3.1 and 15W, while most other phones were 3.2 and 45W charging.
If you follow Samsung's upgrades, you may already know that the difference in capacity between the Z Flip 3 and Z Flip 4 is 400mAh. Ironically, the difference between the S9 (15W) and S10 5G (25W) when 25W released was also 400mAh.
Samsung's linear progress aside, the charging difference is only noticeable in the first hour. You can read more about it at https://www.sammobile.com/2019/05/02/how-fast-is-samsung-25w-super-fast-charging where they compared the standards in depth.

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.
