How well does adaptive fast charging for you?

Any one actually time how fast their note 4 charges for them? Mine didnt seem to charge any faster than my GS4 the last few days so I finally set a timer, and it charged 50% in just over an hour and a half. Way off what samsung claimed, considering this was supposed to take only 30 minutes...and yes I have fast charging enabled and am using the fast charging adapter.

In 20 minutes charged about 33%. I am happy, cause fast charging working very well. From 25% to 95 % in 60 minutes.

I've done measurements this morning after getting my Note 4 last night.
I agree. I've found little difference between fast charging, and normal at the levels i was measuring.
Perhaps it works faster between 0 and 50%, which seems to be the stats Samsung always quoted. If there is any kind of intelligence circutry going on, it must be varying the amount of ampage being drawn from the charger.
I've found the amps drawn to be VERY low as compared with the S5. Obviously the voltage is the main thing changing with Samsung's "fast Charging" plug.
For example changing from 90% to 100% I found:
USB 2 lead supplied with phone + normal plug = 23mins 31 seconds
USB 2 lead supplied with phone + fast charging plug supplied by Samsung = 23 mins dead.
31 seconds difference is hardly stallar!
Yes you can say it depends on what apps were consuming resource in the background, but it was just standard apps synching etc.
Screen was off the entire time, and nothing processor intensive was actively running.
But I did notice something interesting:
If watts = amps x volts it might explain why the phone isn't charging that fast at the 90% level.
Note 4:
With anker 40w 5-port charge (capable of outpitting 2.4 amps per port, the typical draw was between 300 and 450 ma
With Samsung fast charger it was drawing between 250 and 350ma.
Obviously I'm not counting voltage, which will definitely play a part in the overall wattage. But there has to be some kind of intelligence here controlling it as it's not steady.
S5:
Anker 5-port: 1200ma steady
Fast charger (not compatable of course): 1200ma Steady
Which is also intereting seeing as the max output is 1800ma, so the phone still isnt drawing the max it could do.
Might try draining the Note 4 down even more, and seeing if it does up the draw when the battery is nearing empty

I was very impressed with the charging.
The ultimate test for me was when I was playing a fairly graphics hungry game whilst being connected to the fast charger. It continued to charge the phone up to 100% from 30% in around 40 minutes whilst playing.
I believe the best way to ensure the results are comparable is to make sure the phone is completely powered down and the battery has had a handful of recharge cycles first.
Anyhow, I am impressed with the charging and the battery consumption of my Note 4 to date
.

Impressive. Considering you were using a lot of screen and processing power. Sounds like a wait and see is in order, see how it pans out.
Battery life doesn't seem bad for what I have used, not but much better than I had on the S5. In time I expect things to improve though.

With me fast charging work very well
30 mins then 50% when playing some small game and surfing web
Sent from my SM-N910L using XDA Free mobile app

I went from 21% to 75% in about 40 minutes the other day (was monitoring), but my device was on and I had used it a few times in between that time... fast charging is really meant to be used when your device is OFF - that's where you'll get the most benefit.

Mine works fine. Remember it works while screen is off or phone powered down. Also from 0-50 only. Beyond that and it will use 5v to charge instead of the 9v. That's why Fast Charging will only work with the charger it came with.

Are you still having the same issue?
Im charging my phone for the first time and i dont find the fast charging works well with me. Its been an hour already and my battery is still at 30%. I also turn off my phone to make sure i get the 30mins 50% but no luck. Should fast charging kicks in after several recharge cycle?

Remember, it's called adaptive fast charging so it's charging rate varies depending on variables such as temperature, etc.
I went from 20% to 96% in about 60-90 minutes today. Not too bad.
I don't plan on using fast charging much to test, but it's my first few days with the phone and I've been stress testing it to see how battery life is.

90mins for me from 1% to 100%.

no problem at all. been charging from 0 to 100% at exactly 60mins

Impressed with mine used to have a spare battery but not anymore as the beast can really fast.

Must use included charger and CABLE
I found that for fast charging to work you must use the cable and charger that shipped with the Note 4.

hey and im sorry to dig this thread out again, but wondering if another tried fast charging with third party battery, I bought a ravpower note 4 battery off amazon and charged it with my note 4 adapter and I went from 10% to 50% in about 50 minutes, im sure its not fast enough.

note 4 adaptive fast charging
The phone has a chip and the charger has a chip it is this that allows the phone to charge at 9v only between 0 to 50. It's easy for people to be unimpressed because Samsung typically charge quickly. I tried a LG g3 for a few days and it charged ridiculously slow compared to a Samsung if it is taking an hr and a half to charge your phone halfway I would consider using your warranty for a new device or battery

is this correct?
It will only do fast charging below 50%?
What if it starts at 45% - will it stop when it gets to 50%?

I'm finding that Adaptive Fast Charging (AFC) only works (phone reads "fast charging") when the charge cycle is started while the phone's battery is almost dead. Now, "almost dead" means different things to different people, but my GS6 won't use AFC unless it's really low - I know it won't kick on/in circa 35%, but I don't know the precise level.
Here's some an interesting comment made on the awesome article at the link below:
"You should note though, that CABLES DO MATTER. Every el-cheapo ebay cable isn't supported for quick charging. They usually allow about 700mA to pass through. You need high quality cables that probably came with your smartphone in order for quick charging to work. I have done several tests with my Note 4 with several cables and an adapter that meters the output Amperage."

Works great for me take about an hour and 40 mins from 4-fully charged.

I lost my charger so i cant help here
Been looking all over eBay & Amazon, but nothing...*sigh*

TurboCharger is back and is very quick with the USB Type C port. I can get to 100% in about an hour, sometimes a little less.

Same here I find it impressive that they are beating some of the flagships!

G6 play takes about 2 hours give or take to fill a 4000 mah battery. Wish there was a feature to slow charge at night though!

Standard PD 9v charger works perfectly, and it charges quickly even with standard 5v 3A external battery

Moto G6 takes about 60 min from 10% if not using/turned off. About 90-120 minutes if you use it while charging to get to 100%. I notice it takes a solid 5-10 min from 98-100% trickle charger to peak voltage.

My Moto G6 takes atleast 80 minutes to get to 90% then take a lot of time to get to 100% .. like it takes less than 2 hours to get full charge..
But battery drains too fast untill 90% then drains normally ..
Please help with Charging speed...

Moto g6 plus and Xiaomi power bank 10000 pro. Quick Charge not working, 5v 1.6 may max

No issue with the autonomy.

using my quickcharge 3 accessories I get to a full charge in just over an hour using the original cable.

if your rooted check out build.prop tweaks there are plenty of ways to do what your looking for

It charges so fast and consumes so little I was pleasantly surprised

A bit above average, gets through the day with regular use. Nothing impressive.

The fastest charging phone I've aver had. Love it.

Hi there Abby, would you mind explaining to a noob how you managed to charge it so quick, it took me 4 hours to get 90% today with the stock charger. How do I get it to make use of quick charge

Nothing . Whenever I buy a new mobile I deplete its battery to 0% so that it turns OFF itself and then plug it to charger till it is 100% and then switch it ON .
Repeat this cycle 2-3 times and hopefully you'll be good to go.

Nex has AI based Battery charging mathod.
When you charge this in day time it takes less time to charge compare to charging at night time.
My Nex Charged from 10 to 100 in 45 to 60 mins depends on interval in between charging.
At night it takes more then 60 mins ..

Check the where to buy thread around page 30...someone explained that the Nex got shipped with a charger that doesn't support fast charging(picks included). Also, as I understand, when it fast charges it makes some kind of an animation..like a thunder..on the screen. Good luck

I purchased mine in India. I have to use a type-B plug adapter. Vivo told me they don't manufacture a type-B charger. There is no after-market charger that will support fast charge.
When you plug into fast charge the charging icon turns yellow and spins faster. It also says "dual core fast charging"

I measured the charging time today on the turned off screen.
0-30% 15min
0-50% 25min
0-70% 35min
0-90% 60min
0-100% 1h 25min
I sorry for my English, I use Google Translate.

The simple answer is your cable. Assuming the charging brick you're using is fast charge or from Vivo, it's the CABLE that truly dictates the charging speed.
You need a 28/24 gauge bound cable. When you buy cables, they're not all created equally. I have tested this with another fast charge brick and a purchased 28/24 gauge wire cable and it activates the quick-charge function on the phone. Any other combination of cables that are non 28/24 gauge and you can't fast charge with the phone.
So to summarize:
-charging source needs to be the fast charge brick from Vivo or another fast charge capable brick charger
-You NEED a 28/24 gauge cable, no other type will work with fast charge

I asked Vivo in Facebook about how to charge my phone and they told me that its better to net let your phone be charged from 0-20% but higher than that . and you shouldnt play while the phone charging , also if its a brand new , when you unbox it its not reccomended to wait the battery to die and then to charge it to 100 % cause its allready been activated (the battery).

Check my previous post. While it is maybe true, most new age lithium ion batteries are built with decent to sufficient resistance to memory half life.
The real key is exactly as I explained in my post, in that it really has to do with the charging block and more importantly be cable gauge size. Most places don't sell 28/24 gauge cables as their primary USB cable type, C, micro, etc.
So remember:
-Need fast-charge brick (original or other)
-NEED 28/24 gauge, type doesn't matter so long as it's that gauge
Meet those requirements and you'll have fast-charge on this or any other capable device.

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Mi Mix 3 can charge. A higher rating indicates that it charges extremely fast.

I have done some testing.
With QC 2.0 (my old Motorola Turbo charge 15) I charge phone from 20% to 90% with rate 65%/hour (1 hour and 10 minutes time)
With QC 3.0 (charger and cable from original Chinese packaging) I charge phone form 30% to 87% with rate 95%/hour (40 minutes)
I think this scenario is common for most users when they need to charge phone in hurry.
Later I will add also charging rate for quick wireless charger included in box and maybe also some QC 4.0+ if I get my hands on some.

In my case, I bought a PD3.0 charger from Aukey and my Mi Mix 3 is charging from 0% to 100% in 1h08 !
In fact after a few research I found that Power Delivery Technology is compatible with Qualcomm Quick Charge because Quick charge is working with Power Delivery and add a few security technology, but power delivery already have some.
Nevermind, I tested it and indeed My PD3.0 charger (max 15V and 3A) with a anker cable wich support up to 5A is working faster than the QC3 charger !
I suppose a QC4.0 should be better, but for now I think PD3.0 is the best solution !

I second @romain1672...I've converted all my chargers to USB-PD since I've divested from non-USB-C devices and my Mi Mix 3 flies with them.

I believe the wireless charging is relatively slow, think one review said three hours for full charge? But that's expected to be honest.
I've heard it said that slow charging is better for battery life, so in effect, wouldn't the wireless charger be better than cabled, if you're not pressed for time?

It took me exactly 1h45 to charge from 17% to 100% with the wireless charger. It's pretty fast for a wireless charger, but the only issue is that it heats lot of more than wired, and i read somewhere that heat isn't good for battery health.

Hi guys, I just bought the Razer Phone charger (it's the only one I could get quickly with Quick Charge 4.0+ in the UK). Not the most scientific of tests, but it went from 30% to 87% in 30 mins. I tested from 30% again today with a Quick Charge 3 charger and in 30 minutes it made it to 80%.
Sorry I didn't run from 0-100%, I can probably test that more easily this weekend if people are interested?

Fast enough that for the first time since owning a smart phone I never have to think about looking for a charge, even when travelling.

Does anyone know of any wireless chargers/charging stands that charge the mix 3 as fast as the included one? I've tried a couple I had with previous phones and they just charge so much slower

This charger is becoming annoying.
I place my phone on the puck by my bed. Sometimes, before falling asleep, I hear the sound indicating charge stopping.
Then, in the morning I find my phone has moved off the puck. And it is not me! The phone slips away if not perfectly aligned centrally on the puck. It is not surprising as the induction forces between the puck and phone will be opposing but the manufacturer should have spotted this and made the puck/phone with more friction between them.

Bro, I use my brothers Samsung Wireless Charger "EP-NG930" from his S8. Google it to see it. I can't post a pic of it since I leave it in the office but underneath it is rated at 9V 1.67A (15W)
I must say it charges pretty much the same, if not, faster than the included one since it has a built-in noiseless fan behind the coils

I let my phone get down to 1 percent before charging it. I was halfway trying to pay attention as it charged tonight. It was 40% when I looked 16 minutes in. I forgot about it and looked at the phone and it was at 100% after an hour. It was probably even less than an hour.

In terms of drinking red bull, i guess the phone charges about as fast as my drinking a can of red bull. Kinda quick but not fully charged.
0 to 20 in less than 10mins
0 to 50 in bout 25 mins
full charge takes an hour exact for mine

It charges very quickly. About two cups of coffee. Maybe three. (I don't do Red Bull. It tastes like transmission fluid.)

Since my last OTA update it takes 2 to 3 hours to get the phone fully charged

It just like the advertised 70% in 30 minutes +- 1 minute full charge around 45-50 mimutes.

My OP7T charges 50% in half hr but as OnePlus says it charges 65% in half that's not the case here. And it take around 1hr 20mins tho charge 100%. I don't know what's the issue here

Its too strange. Maybe something wrong with your adapter. Do you get a "Warp Charging" text in lock screen when you charge ur phone?

0 to 90% in 40mins... the last 10% takes longer time to charge...but it is best fast charging i have ever used..

My mobile take only 45 minutes for 100% charging

It's charge rapidly then other phones. I truly appreciate one plus battery drainage is very less and having fast charging.
