How fast is fast charging ?

I plugged my Samsung fast charger into my S6 when the battery level was at 65% and then plugged my older non fast charger in and the time remaining gave me similar times on both chargers.
I thought fast charger was meant to be a lot faster ?
I've never charged from completely flat yet.

Fast charge is only for the first 40-50 % then it gets the charging rate of a normal charger...
Marketing magic
Although it does help for a quick boost.. if you're in a hurry to get some juice in the phone.

Samsung's adaptive fast charger varies from 1 - 2A. So the maximum rate is 2A, which is not any faster than other 2A charger.

How long would it take to charge from 0-50% and 0-100% ?

For me it takes 75 minutes from about 15% to 100%.

0-100 % is 125 minutes. That is the fastest on the market IIRC

First and foremost, our fast chargers "charge" our phones at 9.0V ~1,67A

Fast Charging?!?

Hello.
Can someone explain me how on earth does fart charging works on this device?
I've tried the included cable and charger, third party chargers and i don't see any fast charging going on?!? or any indication on screen that it's happening.
I've read somewhere that you need a special cable to use with the included charger (?!?!) is this true? where do you get this cable?
Phone is amazing but the charging part is really is really weird if you ask me.
Thanks.

do you get any message saying fast charging?

it doesnt show any fast charging message, so i wouldnt rely on such a message to make sure its working. just use the included cable and charger and ull be fine it takes about 2.5 hours to charge from 0-100% via fastcharge

Yeah ...That's why I asked. I plugged a meter to the charger and never saw it go more than 5v 2a.
I think it needs a special cable for the 9v but I can't find any info.
2.5h is not fast charge. My old s6 edge plus used to take around 70-80 m from 5-100% if if you put the remaining 1000mah shouldn't take that long lol

Mean in 30 min 40% recharge . My phone 0 -100% charged in 2:00

trust me, it is fast charge
calculate for yourself: original huawei charger is rated at 9V 2A, thats 18W total. 2A is 2000 mA. mate 8 battery is 4000 mAh.
best case scenario: 4000 mAh / 2000 mA = 2h
now add to that the extra time it needs to charge from 85-100%, because at 85% it automatically slows down charging to prolong the health of the battery and youre at the 2.5h FAST CHARGING time
also, i dont believe for a SECOND that the S6 edge+ charged that fast in your case. check this review: http://www.trustedreviews.com/samsung-galaxy-s6-edge-plus-review-battery-life-and-verdict-page-6
"Fast charging comes as standard with the S6 Edge+ and it works. It charged from 0 to 100% in just 1 hour 45 minutes. Samsung claims wireless charging has also been improved – it’s 27% faster on the Edge+ compared to the normal S6 and S6 Edge."
so thats 105 minutes for 3000 mAh. add to that 33.3% to get to 4000 mAh and u get a total charging time of..... 140 minutes. which is 2 hours and 20 minutes

I will make a full test from 0 to 100. I only charged from 40 to 100 and it took way more than 2 hours... that's why i asked if any special cable was needed. And as i told i mesured the charging rate coming out of the charger and never passed the 5V.
As for non Believing. It's REALLY pisses me off when people write that crap. Why would I lie? what would i gain from it? I sold the phone because i wasn't happy with it.... On the contrary and in case you don't know most sites like the ones you post are PAID to give positive reviews.

I checked with including charger and cable and the app Ampére and it charged with 2800mah. So, in ideaal situation it means a charging time of a proximity 1h and 26min. That means "fast charging". At least in my opinion. ?

that doesnt make sense what ure saying because in this case the site actually stated a HIGHER amount of minutes that it would take the s6 edge plus to fully charge from 0-100% so what now, theyre getting paid to write negative reviews as well?
also, no, ure not "gaining" anything from that, but people tend to exaggerate a lot, do a quick "drive by" in a thread and post random statements based on non-correctly remembered experiences and this is exactly how false statements are converted into "truths / facts". read my post and tell me where exactly i listed anything wrong. check various reviews on the mate 8, they all stare the same thing: about 2.5h for a full charge, give or take 10-20 min. it also compares perfectly with the charging time of the s6 edge+ in terms of mAh/min, and in fact these two phones are indeed VERY close, mate 8 being at 49mAh/min and the s6 series at around 50-52, so just marginally faster... which, again, is also represented by the numbers i listed in my post before
and again: there is NO extra message or notification stating ure in fast charge mode on the mate 8, it just does its job, thats it!
if ure getting slower charging rates / voltages, make sure to use the original charger and original cable and both with a proper high voltage power outlet.

I noticed the fast charging only really kicks in if you leave your phone alone. But if you keep using it while it's charging, it just charges at regular speed. But the moment I put the phone down and screen of for 5 minutes, it quick charges like crazy

I hadn't tested this. After i turn off my phone, a few minutes later it jumps to 9V 2A on my meter. If you turn it back on it goes down to 5V 1A. Must be a phone security thing, which is kinda cool in a way if you ask me.
Btw Apparently quick charge works with non original chargers too. I have a Cheotech 60W 6 port usb with 2 Quick charge ports (which supports 9V 2A/ 12V 1.5A) and it works Using the original cable though.

Don't use fast charging unless you really need it.
Always fast charging overnite (when you're not actually using the phone for many hours) can only shorten your battery longevity more quickly then with normal charging.

When I'm going to recharge for many hours overnite I use a 1A travel charger.

i guess thats the best way to restrict charging amperage although it shouldnt hurt the battery so much, considering that the amperage drops off sharply once level reaches 85% and above...
Sent from my Huawei Mate 8 NXT-AL10 using Tapatalk

Charging a phone with a lower rated current, will cause the charger to "try and match" the current requested.
Amps work in that manner, the device determines the draw. For example, using a 5v 5a (theoretical device) on a 5v 1a device will likely melt your adapter / screw up your phone from improper voltages.
In that case, an adapter may heat up, or if its smart enough (unlikely), it will turn off periodically. Most of the time, it will have an unstable voltage (undervolting) which is how some phones are able to detect an improper charger is used. This is bad for your battery.
I do not recommend charging with a charger that isn't rated for it. This is widely documented.

XZ's battery charge time is 2.5 hour from 25%, is it normal?

I turned on battery care mode.

Battery care is turned on?

Mine also came with a slow charger. When I plug it to my portable battery, it can still be pretty fast (and hot...)

With stock UCH 12 charger it takes my phone about 1,5h to get fully charge. 30min to 60% and 1h for the rest. It seems like Sony disabled any type of QuickCharge above 60% to prevent battery damage and it doesnt matter what type of charger you would use alter that - it will stick to 1000mA all the time.
Two things:
1) are you using QuickCharge charger?
2) do you or any of your apps use phone while charging?
Any of those would prolong charging time.

Try to keep it turned on then. I guess Sony could set offline charging to minimal settings and control QuickCharge with software. Try "Ampere" app to check how many ampers are you getting while charging (download from play store, no root required). It should oscillate from 700mA to 2500mA. If not (e.g. stuck at 1000mA) it means your charger could be defective and should be exchange for new one.

man. I got 75% in an hour while the phone was off :/ using the same charger as yours so there must be a problem, try to change the cable

Guys does anyone know if the USB type-C cable which comes with the non-fast charger is 3.0 Quick Charge compatible?? I've ordered a Anker 3.0 Quick Charge charger just wanted to make sure the cable is.

My case is even worse, tales 3 hours to charge from 13% to 97%
I am even using the newest Sony 3A usb c to c quick charger!
What the hell..

XZ support QC 3.0 so it should be able to charge from 0%(theoretically) up to 100% 1h40-1h50 using a QC 3.0.
During my few weeks i've had this phone (recived with UCH20 charger) i tried to test phone's ability to charge quickly and failed it took usually 2-2h20 min with original charger. I've ordered chinese charger (sony's UCH12W is 4 times more expensive, even samsungs and htc chargers are much more cheaper).
During tests (using ampre) i tried to start charging when battery dropped to 10%. I used 2 charges original UCH20,Tronsmart WC1T and 3 USB-C cables 1x original, 1x unknown chinese, 1x tronsmart(original included with a charger).
Conclusion:
UCH20 is slower, Ampere won't show more than 1560mA 10-60/70% then something around 1100mA and 780 or less 90-100%
WC1T is faster, 10-60% 2220mA (or less depends on throttling/temperature) then about 1500mA to 90% and less than 1000mA (usually 500-800mA) 90-100%
Tested with onvo adaptive charging on, stamina off, wifi on, brightness auto (0-40%), there was no difference betwen cables only unknown chinese cable was slightly slower but that is only my opinion. Battery temperature oscylated between 26-37/38°C(Ampere)
This phone will only fast charge up to 60/70% then it slows down a bit and last 10% is slow, it should preserve battery health yet still allow you to charge it quickly when in a hurry so u can use it for another few hours until you'll get back home and plug it for a night.

Good post, thanks for sharing,
I ve recently brought Anker PowerPort+1 charger QC3.0 compatible and used stock Sony cable and max output I got was 2180mA max using Ampere too.. What my question is now what should the XZ be drawing max? near 3000mA?? Battery care Off.
Ive ordered PortaPow 20AWG cable it states its also QC3.0 compatible so lets see how much it get and if it makes any difference to the charge times.
I will post my results in the next 2 days.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the OnePlus 5 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

It's about not only charging speeds... But also the heat while charging
And in both situations, dash charge is superior to any quickcharge solution i've tested.

I can confirm. Alot faster and still cool battery. It charges with 3 amperes through than with an anker charger that fills your battery with 1.2 amperes through.

Dash charging is the bomb. Even without the Dash charger, the phone charges awfully fast.

lighting fast

Easily gets through a day with heavy usage with plenty of power left in the battery.

Super fast charging speed.

from 5% to 100% at 68 minutes. No limits ROM, bluspark kernel

I don't think my phones ever overheated.
Dash charge works phenomenally well, I've never known a charger this fast.
Problem for me is I have a tonne of other USB-C chargers which even though they have similar voltage and amp output they sometimes charge slowly or normally, so you would need to buy another dash charge to get the same speeds.
I have another charger (Dash) but no second cable, lost it. Using another USB-C cable doesn't allow Dash, so the cable matters too.

I saw a video on youtube with charge speed comparison between flagship phones, one+5 was fastest there (1 hour 13 mins). pixel 2xl there was around 2 hours 40 mins)

The time connected to the charger isn't exactly a factor here. You could leave it on the charger for days and it likely won't get very hot, because it will only be trickle charging it to keep it at 100%.
Now, there are other things that cause battery life issues, but I was specifically referencing excessive heat, which is the number 1 battery killer.

My girlfriend oneplus 3 after 1.5 year still got 6 h + sot, dash charge is great

If my phone is on, it usually takes an hour or less. Since the last update it has been faster.

DASH charging is super fast, while charging with QC 2.0/3.0 charger or any other charger its reaaaaally slow.

No heating on charging even if i use this beast.
Gets me full charge in around 100 minutes.
Sometimes it charges really quick around one hourin my office (i think power supply in my office is better than my home) but takes 100 minutes at home mostly.

Warp charge slower than advertised

Hi,
for me, the charging speed varies between 50 and 75 minutes for a full charge. It says warp charge 65 on the lockscreen. Any idea, what might cause it being slower than it should be? I am on OOS 11.0.4.5.
Thanks

Mine actually charges faster than advertised. It charges from totally discharged to fully charged in 35 minutes with the phone turned off.

Check to see if you have optimised charging enabled. If you do then that slows down charging.

Thanks, it is switched off. Do you know how much current is used when charging at about 60%? According to 3C, it is between 1,800 and 2,800 mA. Only once, I have seen about 6,000 mA in a similar situation. Somehow this looks rather random to me.

Warp charge is as advertised for me. Any other charger is extremely slow. Gsam shows I'm at about 3400 while charging from 60-70.

I stop paying attention to the current because in the end it doesn't matter what instantaneous current I am seeing. I always see it starts with 5500+ mA for just a few seconds and drop to 3000+. I ignored it and just let it charge (phone on, screen off).
I usually charge from 2x % to 90%, and it takes no longer than 25 minutes most of the time. Averaging 2.5~3% per minute.

Usb cable or usb port of your phone might be at fault.
My 8t takes less than 40 mins even with optimized charging turned on.

Because my phone says Warp charge 65, I do not think charger or cable are broken. I try to avoid uncharging my phone to a low level, so I cannot tell how long it would take from empty to full.
The other observations are like what @zellleonhart is describing. I had just wanted to rule out hardware issues for a new device.

That used to happen to me. 65w would only happen for some charges and other times it would be slower taking over an hour to fully charge. Now it charges fast every single time in 40 mins or less. Not sure what fixed it but I have a t mobile variant converted to the latest eu 11.0.5.6 and optimized charging off. I don't always charge full but the first 15-20 mins being fast seems important imo since that can be done after waking up and getting ready

I think we are all forgetting that we aren't charging one 4500 battery but actually two 2250 batteries at the same time. It legitimately charges from 0-100 in under 40 minutes, I've tested it. The problem is it's not compatible with any other charger I've tried. Quick charge 1,2,3,4 or PD or even the warp 30 from my OnePlus 7 pro. Any other charger I try is like plugging it into a computer and would take 24 hours to charge. OnePlus definitely messed something up and really needs to fix it soon.

My original observation (and this was confirmed by multiple people now) was that using the original charger and cable, charging speed varies a lot and only sometimes had cuurents for a few mins, which could charge in 40 mins if it would be constantly at that rate.
Your comment about slow charges using other chargers unfortunately is very true. I have tries lots of combinations (chargers for Macbook Pro, Xiaomi phones, older Oneplus chargers and cables from 3T) and the fastest of these would need about 3-4h and the slowest about 10-12h (estimates based on current).

My phone has charged at the advertised speeds every single time I've ever plugged in the warp charger. It charges my phone everyday from 20%-80% in 18 minutes. I've charged it from 0-100 in 38 minutes.

Since I did that, the charging speed was always as fast as Oneplus states.

No. Haven't used a custom kernel on this phone yet.

Just tried the 30W Warp charger of my OP3T again after installing xXx_NoLimits and now this is also charging relatively fast. Estimated full charge time is 1:35.
And yes, I understand that for some folks the full speed has always worked

This is the absolute best warp charge magnetic cable I and my friends have ever used. Been using it for years now. Both warp and dash changes and better yet. None of my phones have charging port issues ^_^.
