Not at all that long. It usually takes around 2:00-2:10h to charge from 5% to 100% with the standard OnePlus charger.

Charging current is highly dependent on the temperature of the battery.

Can you elaborate a little?

If the battery temperature is higher than 35 degrees, the charging current is 1 amp, if it is below the maximum possible, depending of type %% charge, from 1.9 amps to a minimum when the battery is fully charged

1.45 from 0-100 with anker powerport 10

CHarging is a lot faster when the phone is on as compared to when it is off *observations*

Anker power port link pls.. @albireox

2 Hours!
It takes no more than 2 hous to be fully charged from 0% to 100%

Just completed the test about an hour ago and coincidentally stumbled upon this thread.
From 0% to 100% it took 2 hour 10 minutes.

Even with my old Moto X 750mA charger, it still charges pretty fast...
With all other 2A charger, it's like 1% / minute (1700mA going in with screen on) , so it's around 100-120 Minutes....

mine take just 1 hr 35 min to full charge from 15 % when it hits power saving mode !!

Excellent charging speed.

2 hours from zero to 100
Not as bad as I feared knowing that is didnt have fast charging.. 2 hours.. and thats OK.

I haven't had more than 3 hours yet.

I have a Qualcomm quick charger that charges my OP2 in about one hour...the OP2 charger takes about 2 hours

As far as i know qc is not present in op2 so i dont know how this can be

What Qualcomm qc?

it takes about 2 hours in general

charging - amperage/current quickly drops to ~440mA regardless of battery %

in the last week my battery no longer "quick charges". i have 'Ampere' installed so i'm used too seeing it charge at around 2800mA. i vaguely understand that phones charge quicker up to around 80% and then at a slower rate for the remaining - it's not this.
when I plug in the, current starts at ~1300mA and climbs to just under 3000mA... and drops to ~440mA in a minute or so.
it doesn't appear to be the cable and/or charging block that came with the phone - using a 1A charger from my last phone gets similar results and i purchased a new cable that's compatible with high speed charging.
i really wanted to love this phone.

I have a Samsung quick Charger from a Note5, and it has never quick charged my PureXL (actually super slow charges it,) but after the last update, I noticed I got an overvoltage error using it....

The reason is that this phone is not quick charge enabled. That's actually something that needs to be built into the SoC + Kernel support. You have a solid 2A charger, it'll go fast, but it can't rapid draw like say, the premium motos or a OnePlus.

sorry, i don't think i explained myself that well. i'm pretty sure that i've noticed a change in performance. when the phone was new i remember the current being high when battery % was lower, and then decreasing as it charged.
in the last week or so it seems to be charging at a slower rate and with the original 2A charger and cable. if the battery is at 20% the current will increase quickly to something above 2800mA and then immediately decrease so that by the time it's at say 22% charged the current is at a steady 440mA.
oh! ****. i didn't realize that 'quick charge' was actually 'Quick Charge™ by Qualcomm®'.. nice and generic sounding.

my pure xl was doing a full charge in less than 3 hours. as of last week all of a sudden it takes 10 hours to fully charge. using original charger and cable. can anyone shed a light on fixing this problem?

My Nexus 6p is now facing the same problem as yours. It charges less than 3 hours before and all of a sudden two days ago, it has taken 10 hours to fully charge. With all cables and charges faults ruled out, my only guess is the fault lies in the phone. I don't think it is the USB port either. I believe it may be something to do with the software I cannot comprehend. But I currently don't have the time to reflash my ROM. This Resurrection remix ROM served well for the past year.
Currently, my amperage averages out to 350 mA. Sad. I wish someone with knowledge about this can reply to this thread. It seems this question has been lingering here for more than two years already. Are we the only ones who face this problem?

My battery is at 62%, and on the lockscreen it says 1 hour and 26 minutes until fully charged. I mentioned this in another thread about slow charging in the Q&A section. I don't know if I have a lemon or faulty charger possibly..... Anyone else have any stats to compare with me?

Is charging that bad?
Even I have seen users facing charging issues. This is what is confusing me. Hope someone clears completely if the new model has charging issues or not!

Here's my charging times according to Battery Widget Reborn.

it's quite a bit slower to charge with the included charger than my G4 with a QC2.0, but it's not terrible.

I do know that using the phone while it's charging will cause charging to take longer. I've installed Ampere to monitor the charging current, and it fluctuates wildly between 510 mA to 3350 mA it seems like. Hopefully someone else can install Ampere and compare stats, would be helpful.

Seems a bit slow for Quick Charge 3.0 but perhaps it is due to the version they are using which is 1.0 or something like that

At 16% I have measured up to 3250, but haven't tested very much.

So the phone takes about 2 hours 10 minutes to charge from 1% - 100%, and that's without using the phone during charging. Is that about the charging time other people are getting with the bundled charger? Still seems very slow compared to other flagship phones out there (my last phone was the Axon 7 with Qualcomm QC 3.0).

The charger itself (the box plugged into the wall or into a car 12V socket), offering a USB socket. The job of this element is to offer a stable 5 volts at the USB socket.

Hmmm, if I put the phone down, and clear all apps, the phone charges an average 35% per hour. I do have a ton of [email protected] running in the background, but that's the rate I get with the included charger. good? Bad?

I found that if you use the phone while charging, the charging almost comes to a standstill. Even when not using it, i can't see how Google can advertise up to 7 hours of use on a 15 minute charge

OK, I am reading posts like that this phone charges fully in 2 hours! Is that right? I mean from 0 to 100, it takes 2 hours? Is this some sort of joke? Rapid Charging and 2 hours? What am I missing here?

Yeah, in the google commercial for the pixel it says different. The commercial says it will charge 7 hours of up time in 15 min. That's def not the case with me.

I have Google Pixel XL and when I charge it from 0% it doesn't even get anywhere close to 100% in 15 minutes

I kind of want to get a OnePlus 3t because I miss the Dash charging from when I had the 3. That being said, charging speed is one of the only complaints I have about this phone which is pretty good I'd say.

My phone charged from 8% to about 90% in 1h30m

These are not good charge times. My Note 5 from 0% to 100% using their adaptive quick charger is 1 hour 5 minutes.

Poor charging times. 15 percentage in 15 minutes. Phone went to 29% from 14%. Zero usage in between obviously, wanted to measure that only.

Is the included charger the best or would a 3rd party wall charger be faster?
I ask because my LG V20 came with a QuickCharge 1.0 or 2.0 charger even though it's a QC 3.0 device. I am wondering if Google did something similar here?

dash charge (now called fast charge) is crazy fast!!

Still, I would only recommend using that feature if there is a real benefit - i.e. time is of the essence. The battery will age quicker being dash charged all the time.

saw 60 percent at 35 minutes and 38 seconds, which is more or less in line with what OnePlus claims

Incredibly fast compared to my old Honor 8. One example I have is the first charge I did 5 days ago when I had bought it at a pop-up event here in Sweden. I had used it for about 1-2 hours with the screen on when I was setting it up and trying out the phone. Then when I plugged it in, it went from 36% to 75% in just 24 minutes. That's insanely fast
I've also noticed that just like OnePlus claims, the phone basically charges at the same speed with the screen on as if I would have had the screen off.

Can you provide any factual basis for this statement? Research or articles from established professionals in the field of battery charging?
Everything I've read from reliable sources state that the biggest impact on battery longevity is temperature. Repeated heating (or extreme cooling for that matter) will accelerate the "aging" process, as you put it. OnePlus has actually solved this problem by offloading the energy conversion that causes heat to the power brick, leaving the phone cool during charging (pretty ingenious). I've also read that not always charging the battery fully to 100% can prolong longevity, which is why you get charging strategies on laptops that will stop charging at 80% or 60% if you leave your laptop plugged in 24/7.
Point being, the ONLY way to slowly charge this device would be to use a third party charger and/or cable.
The reason I ask this, is that the manufacturer, OnePlus, clearly states in their documentation that comes with the phone or dash chargers to ONLY use the charger and cable that came with the phone.
Please charge the OnePlus Dash device only with the official Dash Power Adapter and Dash Type-C Cable. Using unauthorized adapter can be dangerous and may void your warranty.

I'm not completely opposed to the idea that this could just be a marketing ploy to get you to buy their own adapter and accessories, but again just want to know if there's any substantial proof that fast charging, by itself, degrades the battery faster, of if it's just a case of incorrect tribal knowledge.
Thanks.

You are correct that the rate of charge and discharge alone are not the only deciding factors on lipo life and certainly not the most decisive ones.
Excessive heat, especially on high charge levels, is the biggest factor for increased aging.
As you mentioned extreme charging levels (completely empty or full) will also contribute to faster aging, albeit the impact is not that extreme for these low current-draw Lipos used in our phones (as opposed to high-drain Lipos for instance).
Discharge and Charge at high rates will also contribute to the speed of aging, but not as much as heat.
When a lipo spends most of its time one medium charging levels at moderate temperatures and is only charged and discharged with low rates on it will have the longest service life.
This is common for all Lipos, just how much a low or high rate is for that particular battery differs (low drain, high capacity VS high drain, low capacity cell)
With Lipos everything is a compromise. Max and min voltages, max temperatures, max draw are values the manufacturer has chosen as the best compromise to reach the intended MTBF. All these numbers are not physical absolute barriers.

Second place after SuperCharge (even first gen) from Huawei. Much better than QC 3.0

First of all, how many device support Super VOOC? How many device you can buy outside China with VOOC?
Super VOOC is 50W, the same like Huaweis SuperCharge 2.
Did you test SuperCharge 2 or VOOC?

My OP6T charges up to 100% in 1hr 22mins, so I don't charge overnight anymore. Go to sleep on 40% and charge in the morning

The combo of battery life and crazy fast charging is for the first time breaking me of the "plug it in overnight" habit that I have had since my first cell phone over a decade ago. I can keep my charger at my desk, plug it in for half an hour, and be at 100% with almost no chance of running out before the next morning. That means fewer vampire chargers around the house wasting power, and fewer charge cycles lost leaving the phone plugged in long after it's full. I wish I had swapped to OnePlus sooner - I think I have finally found a phone maker to call my favorite.

The charging Speed with "Dash charge" is amazing.
Within few minutes the battery is from 0% to over 50%!
Generelly I can only say: Amazing battery life. The best I ever had with a phone (except Nokia 3310).

I started to charge when the battery was 5%. It took around 1 hour 20 mins. I can say this to be quite faster when compared to the devices I have used previously, that too when the size of the battery is much bigger than the previous phones.

The incredibly fast charging, coupled with the insane battery life (especially in dark mode) has made me totally OK with no wireless charging. I used to leave my phone on the charging pad at my desk most of the day, and on my nightstand charging pad overnight. I never had to worry about charging at all and plugged in maybe 20 times max over the last two years with my Note5. I said I'd never buy a phone without wireless charging, but the $350 or so I got for my Note5 exchange for this phone was just too tempting to overlook, particularly if it set up my family for the next two to three years (our current phones didn't have band 71 and Samsung said no more security updates). The only thing I was really worried about was wireless charging and whether or not the battery life and dash charging would be enough for me to overcome range anxiety.
It has.

So I'm thinking of keeping my dash charger at home ,and my 30w aukey charger at work ,I take it this will be ok to use ?

It should be. If you are starting from full in the morning I doubt you will even need the charger are work except for very rare instances. I have gotten 7 hours SOT that was mostly gaming on this thing, moderate use you can easily get 24 hours, light use around 48.

How slow are we talking; how long does it take for it to go from 0% to a 100%?
Sent from my Mi A1 using XDA Labs

About 2hrs and 15 mins. And this is when you don't use your phone while charging at all.

Sent from my Mi A1 using XDA Labs

it took me 1 hr 35min to charge from 10-100%.
getting battery backup of 1 day & 2,4 hours above
no gaming(not a mobile gamer)

Charging are so slow it tooks atleast 2 hours to get full charge, and is not acceptable. What year is it? 2016? My other phone with lower price than this can perform 35% faster.

Pretty fast, especially when using QC3.0 charger.
0-80% is fast, but 80-100% is pretty slow in my opinion. It's a good thing tho, makes the battery last longer.

Fast charging should refer to the initial phase. If you plug in for 20 minutes it should give you enough power for atleast 5-6 hours. Sadly, that is not happening over here.

Some people here say that their device takes longer to charge and all. I say there a some important factors to consider -
1. Heat of the Device - How hot it was when you put it on charge. If it is hot, then definitely your phones regulator will reduce the amount of charge let into the phone.
2. Ambient Temperature - If the climate is hot, then automatically fast charging will increase device temperature. And as Black color absorbs more heat energy phones temperature will naturally be more than in a chilled room. (All phones are susceptible to this phenomenon, I've Experienced this first hand) and more heat = low speed charging
3. Power Outlet - The power outlet at which the charger is connected also plays a very important role. Pretty Self explanatory.
My Phone takes around 1:40 - 1:50Hrs at normal temps(ambient and device), while 2:30Hrs in a very hot condition.

too slow , it takes me over 2 hours to 25% to fully charge
