Ok to start of i bought a car charger that has 2.4amp and a blue socket. I thought it may fast charge but nope regular charge, then i learn qualicom 2.0 is fast charge and i dont understand why fast charger doesnt equal 2.4amp. Then i realized to fast charge eith the mathews app you needed the supported kernal, now that the pshycial charger supports fast charge, kernal supports fast charger, is it 100% fast charge? Kernal, wire, socket. Also...is there a kernal tweak like from synapse to charge faster? And last question) i saw qulaicom 3.0 is out...does note work with it or is limited to 2.0?
Sorry but you just went in 3 different directions you lost me with all your questions a d talking
Yea, basically it all started when i was on the note 3 and i noticed this fast charge app said you needed a kernal that supported it. Then the fast charge feature came out by Samsung software itself, and the adaptive fast outlet it self. So fast charing was introduced by kernal, software, and now hardware. I know kernals can increase performance by increase voltage or decreasing, is there any kernal function like that, that can affect fast charging to be even faster? Then i said a 2.4amp does not fast charge note 5 because qualicom 2.0 is needed, so i adked why isnt a 2.4amp charger not doing the same thint as qualicom. And then i said....on amazon they got a qualicom 3.0 outlet, since note 5 fast chargers on 2.0...will it work on 3.0 speeds? Faster?

I use this one. It's cheap, but it works great. http://amzn.com/B00Y0BPF3C
No, it will not charge faster, although, it will charge at QC 2.0 speed. Any Qualcomm Quick Charge compatible charger should do. If you don't see the logo on the charger you are buying, chances are you will get a fast charge, but not near as fast as the Qualcomm Quick Charge 2.0. Look for this logo:
***The kernel has nothing to do with fast charge, it's worked for me with every sprint kernel out for this phone***
Synapse does not affect the rate of charge for our phone. Regardless of what the settings say the charging rate remains the same. I tested regular, fast, and wireless and they are not affected in any way.
Thanks for info, what about kernal? Why do some support fadt charge others dont. And using synapae can you control how fast or slow it charges?
This phone the n5 already supports fast charging! !! So what are you really looking to accomplish?

fast charge is generally a feature that needs to be built into a custom kernel
Don't know about you but my S5 chargers incredibly fast compared to my SIII and Nexus 7. Even with fast charge on.
Agree, my S5 charges at 1.2A given a charger capable of this, and that is fast.

Yes, the S5 charges at 2amp. (Kernel reports 1800mah)
If your phone is reporting that it charges any slower than that, it's an energy deficiency of the charger supply, bad cable, or bad micro usb connection.
I use an app which reports charging current. With a standard micro usb cable i never morw than 1200 mA (and about 450 mA from a PC/mac usb plug)
Sent from my SM-G900F using Tapatalk
While it's true that the phone ships with a 2A charger, the charging current does not exceed 1.2A AFAIK.
Gotta love MicroUSB 3.0.
It already charges from under 10% to 100% in a mere 2 something hours (bundled charger and USB 3 cable). You want something much faster than that???

Yes I think in the end it is something around this current. What the apps report is more "charging in 1800mA mode" and not really charging with continous/real 1800mA. If you like to know more exactly what the current is you may write down time/percentage values for e.g. every 5% of battery power starting with an nearly empty battery. Then you can draw an line of the effective loading current.
With the original charger you should be able to get stable 1800mA but if the loading circuit of the S5 really goes this high I did not check.
I believe it peaks at 1800mah with the screen off. It is 1200 mah limited when screen is on.
Sorry to awaken this post.
As most of you, my S5 reported charging at stable 1200 mA with wall charger, probably 1800mA when turned off.
But, I can say a custom rom unleash battery charging in the same conditions as stock rom. I get stable 1800 mA with LineageOS, even screen on, with original charger and usb 2 or usb 3 cable.
Hi,
Has anyone tried to charge the Note 3 with a Qualcomm Quick Charge 2.0 charger and does it charge significantly faster?
The reason I ask is that our phone's processor, Snapdragon 800, is listed as supporting Qualcomm Quick Charge 2.0:
https://www.qualcomm.com/products/snapdragon/processors/800
The technology works by ramping up the charging voltage when the battery is low, and slowly reducing voltage as the battery fills up.
This is exactly the same technology which the Note 4 uses and dubs "Adaptive Fast Charging".
The latest Qualcomm Quick Charge 2.0 chargers charge at:
12V * 1.5A = 18W
9V * 2A = 18W
5V * 2A = 10W
(voltage is reduced as battery charges up).
You can see the voltage/amperage of the charger written somewhere on the charger.
Chargers that are 5V/2A only (e.g. stock charger) are not quick charge 2.0.
This is not to be confused with USB 3.0 charging (which is only ~5V * 1A = 5W from PC), or 2A chargers (5V * 2A = 10W from 0 to 100%).
Our Note 3's chipset supports this, but it won't be very surprising if Samsung disables this on the firmware or kernel level.
If anyone has tried charging the Note 3 with a QC 2.0 charger, your input is much appreciated!
I haven't used that charger, but I've been charging at nothing but 2A for quite some time (via kernel settings). It seems like it charges up pretty damn fast, and I haven't noticed any ill-effects from it....
Note 4 charged with quick charge, discharges faster too, so I think it's useless if the battery life decreases.
Maybe it's a problem of the note 4, but I don't think so.

It charges at double speed at <80% (or similar, varies depending on when it throttles to 5W/2A).
Essentially, you can charge up to 60-80% within half hour, as advertised by Qualcomm.
That's extremely useful if you simply want to add 30% to your battery life with 15 minutes of charging before leaving the house, etc.
The difference is more obvious with half hour: 50-60% charge versus 20-30%.
Hi, to which kernel are you referring to old ? Some chancethat it is vcompatible with stock Lollipop ? Thanks
Checked with a multimeter, maximum I can reach is 5V on a Note 4 charger even I am charging from 10% and screen off
Samsung disabled this. Didn't try on 5.0 anyway.

To my knowledge, the Note 4 charger is not a Qualcomm Quick Charge 2.0 charger.
It is a Samsung-proprietary variant for the Note 4 only, and unlike other QC 2.0 chargers only toggles between 5/9V instead of 5/9/12V.
Note 4 however does support the Quick Charge 2.0 standard as well.
Please do correct me if I'm mistaken.

Yep, but the Note 4 charger's adaptive charging is proprietary and restricted to Samsung's Note 4 - it's not a Quick Charge 2.0 charger AFAIK.
Anyone actually tried charging the Note 3 with a Quick Charge 2.0 charger?
e.g. http://www.amazon.com/Tenergy-Unive...d=1421031846&sr=8-1&keywords=quick+charge+2.0
No, but a friend in work has a note 4, I will test tomorrow an post back.
Any specifics you want testing, results with various apps etc?
I don't think so that is supported, but some1 got to try it...

Fast Adaptive charger comes with galaxy s6 i tried this charger on my note 3 but fast charging is not work on note 3 and this charger is intelligent itself to deliver required amount of current to mobile my phone charged simple on 1200mAh to 1800mAh regular current delivered to Note 3 by Fast Adaptive charger when i put it on s6 it automatically detect it and on fast adaptive chrging it gives 9V ,1.97A to maintain high speed charging but not on Note 3
boomWow!
Years later, I've tried my Nexus 6's FastCharge 2.0 AC adapter and it charges significantly faster.
Doesn't charge any faster on stock firmware, checked using ampere , charges at the normal 1200mah with screen on which I believe is the max with the screen on surely there is someway to unlock it
yes it supports you can buy Tech Sense Lab 3.4 Amp Dual USB Car Charger
The ampere app shows my Note 3 charge at a 1.8A from normal 1.2A steady flow, this is with Qualcomm 2.0 QCharge... It is probably the max rate for the device.. It is fast, especially within the lower band of the battery capacity.
With Qualcomm QuickCharge 2.0 the voltage does not ramp down, only the current does. The whole point of QC is to overcome the resistance inherent in many micro-USB cables, and that's done by boosting the voltage. My Note 4 charges at 5V/1.7(ish) amps on a non-QC charger, and 9.4V at the same current on a QC 2.0 charger, and that voltage is maintained throughout the charge with the current ramping down.
My girlfriend's Note 3 does not charge at increased voltage on my QC 2.0 charger. It just does 5V charging.
Measurements were made at the output of the charger with a USB digital multimeter.

I haven't had any problems with battery life on my Note 4, and I quick charge mine frequently. Must be a problem with YOUR Note 4.
My adapter is 9v 2a and i can say it charger significately faster. Alot faster.
Stock charger takes anywhere between 3-6 hours where as mine takes 2-3 hours max.
I have got a replacement battery(chinese one) but is equivalent to the stock samsung battery.
Also i am using a ported rom from the s7 edge so fast charging could possibly be enabled within the kernel especially if the cpu supports it

I know the gs6 doesn't have a Qualcomm chip in it, so doesn't support official quick charge 2.0, but do we have any info about the fast charging it does support?? I'm looking for a fast charger for the car, but only see quick charge 2.0 chargers. Are they cross compatible?? Any suggestions for fast car charging with the gs6??

I'm a little late to this thread but had the same question. Here's what I found (http://www.gsmarena.com/charge_test-review-1239p2.php). I haven't had a chance to test this out yet, I got my mother-in-law and wife both new GS6's and I have a Nexus 6. I have a Puregear Quick Charge 2.0 car charger (http://www.shopandroid.com/puregear-24a-extreme-usb-car-charger/5A255A20438.htm) that I'm going to test on one of their phones (hopefully tomorrow sometime). I can update my post after I do, but if the article I first linked is correct (and it seems like it should be, makes perfect sense) then the chargers should be cross compatible.
I've seen reviews from android central, and its compatible with quick charge 2.0. I actually have one on the way now.
Honestly I do not see any difference between quick charge and fast charge. My n6 used to heat up real quick and high, the s6 doesnt heat up that much. Other than that, the time it takes is almost the same.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Samsung Galaxy S8 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
I got problems with it...
Sometimes it charges really quick, like Quick Charge does. But then sometimes it says it needs about 8 hours to charge fully.
Thats why i voted Average 3* and charging speeds sometimes even differs if i plug it out and in again.
EDIT:
With the original charger which came in the box it works fine and needs about 1h and 40m to fully charge.
1 hour 45 mins normal charge with original cable and adapter S8 rocking stock AQF7 not rooted

OK, the original charger, what is the Voltage & Amperage Output?
Also.....
From 25% to full charge using a QI Wireless Charger and the Original Charger that came with it, how long to full charge?
From 25% to full charge using the USB out on a laptop (.5Amp), how long to full charge?

Hi are you Iranian?
If you doesn't use official Charger of S8 that it's available in Phone Box it's probably correct that your device will not be charged very fast and you have to use the Official and trusted charger of Galaxy s8 that Samsung electronics have confirmed it.
Been using the s8+ for two weeks
Not sure what to say. When i check with Ampere app, it only shows it charges for 1000 maH
I have Xiaomi mi5 which charges for 2000-3000 maH with the same charger
How could samsung lose to Xiaomi?
After the August security patch the fast wireless charging is broken. I have the European version S8 and a choetech wireless fast charger. Does anyone has this problem after the last OTA update?
Just to point out, the fast wireless charging option is activated in the settings but the wireless fast charging is not working, only normal wireless charging.

I was wondering if it was my wireless charger faulty... did you have any source on this bug or it's just your (and mine) experience?
you cant check charging current with ampere app, because Samsung changed charging method a lot after explosive s7.
basically if screen is on charging current drop to ~ 1000mah. and phone use 9v or 12v only if screen is off.
also if you phone charge longer than 2h something is wrong with your charger\wire or phone can't go to sleep properly due to "cancer" apps who prevent full sleep.
But iam here to ask owners of 25watt chargers, is it worth it? how long it takes to charge it with it?
i not sure if link are allowed here but here it is https://www.samsung.com/us/mobile/m...apter-for-galaxy-tabpro-s-25w-ep-ta300cweguj/

1 and half hour and 1 t0 11
Mine charged from 0-100 in around 1:45
Here, Im using Alexis ROM and I hace adaptive fast charge original. Chargimg time: 1-100 in 1.51 hr Its Okay?
I have a note 20u 5g SM-N9860. While tinkering with charging options, I turned on Fast charging and disabled other options. However, when I connect stock charger and cable, it stays on CABLE CHARGING. When I turn on Super Fast Charging, it charges in Super Fast Charging mode.
Is anyone having this problem of not getting Fast Charging mode to work?
I think it depends on the charger. I don't think a super fast charger will just do fast charging. Super fast or just regular. At least that's been my experience.
Using my pixel chargers on the note it does just do fast charging, because that's all the charger is capable of.
There is an option to enable fast charging. There are two different options for fast charging and Super fast charging. Most probably that option is turned off. It is off by default.
I've experienced the same thing. You need to understand electrical currents and how the plug you putting your adaptor inside. To make it simple, use a charger that has usb a to usb c (old ones) for fast charging (samsung branded in my experience). This phone was designed to handle super fast charging anyway, why not use it?
None of the charge options make any sense to me on the N20U. Example , using an old samsung 18W brick charger. On slow charging it peaks to over 2000mA or over , on fast charging it peaks to around 2800mA. Using Accubattery to see value whilst charging. Using a 10W apple brick charger it charges are around 1000mA however.
This behavior was present across three different N20U devices.
Easiest way is to look at the charge indicator.
Around 1% a minute is snail charging.
Around 2% a minute is fast charging.
