Will older OnePlus chargers still Dash Charge (20W) on the OP7P? - OnePlus 7 Pro Questions & Answers

The OP7P will have the Warp Charge (30W), but...
...will my older OnePlus chargers still Dash Charge (20W) on the OP7P?

Great question! I wonder the same thing, I have 4 chargers already! And I really hope they will be compatible.

Wondering the same thing

No guarantee: I've heard you can charge the OnePlus 7 Pro with Dash and older OnePlus Devices with Warp. Of course the charging speed doesn't change.

While I was doing some reverse engineering of the Pie OxygenOS during GravityBox development I came across
some hints leading to believing that older dash chargers should be supported on the newer devices having warp charge.
In particular:
Code:
.method public onFastChargeChanged(I)V
.locals 9
.param p1, "fastChargeType" # I
fastChargeType is later tested for 3 values.
0 - no fast charging
1 - fast charging (which I believe is when old dash charger is used)
2 - warp fast charging
Of course, it is still possible such logic is there to cover different types of devices with different charging designs
but in that case, as a developer, I would rather use different approach - device specific config overlay (framework config) instead of
testing for all possible charging types.

I can confirm: I just plugged my T-Mobile OP7 into my dash charger from my old OP6T and it displayed "Charging rapidly" on the lockscreen.

I used my Dash Charge car charger and it charged up my OPO7 Pro extremely fast.

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.

Can i charge my OP7 pro with a "regular" charger?

Hi,
I just got my new OP7 pro that is replacing my samsung S8.
As i have S8 chargers and even older chargers (like for S6) I wonder if I can use "regular" charger / samsung S8 car charger / xiaomi power bank charger on my OP7 pro?
The warp charger is great but I have only one... and basically the most 2 issues I can think of is charging my OP 7 pro while driving (I have car charger for my old S8)
or while away, I have a xiaomi power bank charger.
So, I would like to know if:
1. is it possible? (probably if so it will charge slower... but it is ok)
2. will it damage my OP 7 pro battery in the long term?
3. Can i Use other USB-C cables?
Thanks for your help.

Charge with any cable. Only warp bank and cable will charge at full speed as you're aware.
So, 1 yes, 2 no 3 yes

And you can charge with DASH chargers too. I do this with my old Oneplus 3T charger and there is no problem. This is not fast as WARP but faster than regular chargers.
Great, thank you all for the answers.

Question on which car charger to get

Will the 45w fast charger for samsung note 10 plus be compatible with warp charge for my 7 Pro? Or, will a oneplus car charger with warp charge still fast charge the note 10 plus??
Or which charger should i get for the fastest charging possible for both phones in mind?

Warp charging is OnePlus specific. It requires heat management on the charger side, and only a Warp-specific charger will do that. I remember from the OnePlus 3T (which had "Dash" charging, of which Warp is just an updated version) folks found that Oppo "VOOC" chargers were compatible with the 3T's Dash charging. One person said that Dash was simply a rebranding of the VOOC fast charging technology (and in fact just same charger but different color and band name on it). Oppo owns a part of OnePlus, and I think OnePlus even uses Oppo's manufacturing facilities, if I remember correctly. So it might be the same with Warp (an Oppo charger may work).
Otherwise, no other charger is going to work unless it says OnePlus and Warp on it.
I don't follow Samsung very closely. I remember their fast charging being proprietary, but not as "picky" as OnePlus. It's not a choice on the OnePlus/Warp side. So you should probably start with the Warp car charger, and see if it fast charges on the Note 10. That's probably the best you can do.
It has definitely become a problem that phone fast-charging technology is not standardized. Too many companies want to use their own proprietary fast charging system, to differentiate themselves from the competition (and to credit OnePlus, Warp is pretty darned impressive!). Qualcomm tried to standardize this, for at least phones with Snapdragon chipsets, with their Quick Charge (QC) technology. But there are even some companies (I think Samsung is one) that disabled QC on Snapdragon phones. And of course, not all phones use Snapdragon chipsets.

Oneplus 6 charges faster with WARP charger

This surprised me but I guess it shouldn't have. Although the original DASH charger is rated at 5V/4A, in my experience (on several devices) it never reaches that maximum rated output (which makes sense as you would overspec the charger for safety) - fastest I've seen the OP6 charge on DASH is 3.3A (though actually I have 2 cables that don't go above 2.7A for some reason).
Obviously, the OP6 can't do proper WARP charging, because it doesn't have 2 separate cells like the OP7. However, when charging with the WARP charger, my OP6 reliably charges at 4A! I guess because it is rated for 5V/6A it has more wiggle room (cooling?) to work with.
So if you happen to need a replacement charger, it does appear to be worth getting a WARP charger.

Question regarding the 8T and warp charge

So I have my 30 watt warp charger from my OnePlus 7T but with my 8T, it charges slower than hell. I get about double the charging speeds when I plug in my 18 Watt PD charger from my pixel 4 XL. I have troubleshooted in every way I can. I've even entered engineer mode and went to the warp charging test, ran the test with the 30 watt warp charger plugged in and the phone recognized it, and it passed the test, showing it was a warp charge 30w. The phone just won't accept anywhere near 30 Watts from it. I want to buy the 65 watt charger that this phone can handle but I'm extremely nervous and don't want to spend that money on the 65 w just to see it do the same thing as the 30 watt. So everyone knows, the 30 watt warp charger is official and my 7T has zero issues with it. Is it possible the OnePlus 8T doesn't support warp charge 30? Anyone experience anything like this?
Is Optimized charging enabled or disabled?
what are the result for each?
I have the same charger leftover from my old 7T, plugged in at another room in my house. Yes, it's slow. It is not nearly as fast as 30W when charging the 7T.
My thinking is that the 8T does not support Warp Charge 30.
