Hello I made this thread so people could post their charging mA with the fast charge, Im getting around 960-1010 mA charge while my phone is plugged... I think my result is kinda low for a fast charge charger, I used my Galaxy Tab S charger on my Nexus 5 and I could get up to 1400 mA! And thats with the "old" snapdragon 800 quick charge, also, it charges much faster than my S6 with only 300 or 400 mAh less capacity than the S6...
What is your current charge mA? You can use Ampere or type current charge in the play store to see how fast your phone charges! Compare with others and see if theres something wrong with your charger or battery.
Sorry about my english I learned it through MMOs.
Here is a picture of my current charge!

Hello
I also use Ampere and with the fast charger it shows about 2700mA charge, but I heard somewhere that the fast charging only works when the screen is off, so you might possibly be getting a lower charge because you are using the phone while charging it, when using the fast charge I don't use my phone at all. You might ask them how am I able to even see the charge if I don't even use my phone? I turne the notification settings on the pro version of ampere so it shows the charge on my lockscreen always

Whats your current charge with screen on? And why is my nexus getting up to 1400 mA when my screen is on when fast charge is supposed to be much faster than the snapdragon 800 quick charge.
Edit: my phone says itll take 31mins to charge from 82% to 100% with fast charge, is that normal?

Uhm I'll first have to test that, and about the lower charge from 82 to 100, it is normal because with the Adaptive Fast Charging you get a high charge initially and towards the end it lowers, that is how it's supposed to work in order to charge the battery properly

If you can charge from 0 to 50% in about 30 minutes. Then it is working fine. It charges much slower after that percentage to protect the battery and etc. It's normal for all fast charging capable phones.

Guys I stopped fast charging after reading that it possibly fries the accelerometer.. I haven't charged by phone with the adaptiv fast charger yet. Use a 5v/6amp charger which is quite slow. Please advise me if I can start using the fast charger without causing issues to accelerometer thanks
Moto g5 plus
I get around 900mah to 1200mah.
I have Moto g5 plus having Quick charge 2.0
Yeah, I can confirm that fast charge only works while the screen is off. The voltage the charger spits out reflects that.
Screen off: 9V
Screen on: 5V

why doesn't the battery charge while it is plugged in while I'm watching a movie or talking to somebody online it's ridiculous amber light never turned green only when it sitting idle
Sent from my ADR6425LVW using xda premium
Most likely because what you're doing, especially the movies is drawing more power than what's actually being pumped into the battery. Get battery monitor widget by "3c" in the market. Very very detailed info about your battery. Ish you never even thought about/existed. Haha. Its very helpful.
Sent from my Re-ZiZzLe Using Unreleased Ish =)
How is it being charged? USB or AC... The answer is important, as USB only charges half as fast as AC.
Regardless, the reason is that if you are using the phone heavily, you are using a lot of power. If you are using a lot of power, you may be using all or almost all of the power coming from the charger just to operate the phone.
I have seen power use rates when using the phone heavily that are around 700mA, that is more than the 500mA that you get when charging via USB, and almost as much as the 1000mA that AC provides.
Heck, I have seen power use rates that are up to 1100mA a few times. That is higher than even the AC input.
Here is a screen shot of my charging over the last 12 days. I have NEVER gotten 1k+ (results may vary. As to why, stated in the following) you can see on the bottom screen the max mA peeked at 972. USB doesn't charge at "half" the mA as wall chargers. I thought that too, but did some tests (while VERY bored at work. Haha) and have seen 600 to around 800 mA. It varies on a number of things.
Ie: the USB cord itself. As some are designed for data only or faster transfer rates rather that charging taking priority. (charging light may be on, but thats just because it knows somethings plugged in. Or you could just have a Bonk one. They're are MANY different USB cables today.
The phones kernel, because you'll notice when the phone is damn near dead, USB or wall, will charge at a higher mA and fluctuate at different battery percentages.
A good/stock kernel will charge super fast when battery is very low to get you somewhat charged quickly. Then in the upper percentages it should slow way down especially in the high 90%'s to effectively complete/finish out the charge rather than just throwing rediculous power into the battery across the whole process. Also what other stuff you may have turned on, on the phone like "enable always on mobile data" may be detrimental. Hope this helps man.

It was only a few times I noticed the power use that high.
USB can vary, but general rule is 500mA can be counted on as that is the max that the standard provides.
All charge rates will vary. The main problem is the fact that we usually charge a device that is powered on. The varied power use will cause fluctuations in charge rate.
I need to research more into how Li-Ion charges when the device is still in use. I do know how they charge when not in use, and all the little details of it. The biggest problem is that powered on really messes with how a Li-Ion battery can charge.
I need to get out my stand alone computerized Li-Ion battery charger and do some testing. I have been wondering exactly how much these batteries hold if actually charged properly. Too bad that the Stock OEM batteries are 3.8v nominal, they charge to a higher overall voltage and my charger is not set up to handle the new voltage so I couldn't charge the stock to a real 100%.
if u charge by AC with a 1000 mA you should be fine
Are you watching the movie on your phone or do you have it connected to a TV? The screen being on will draw a lot of power I believe.
Always always wall charged; only used USB to adb stuff never let it charge via usb

My phone takes about 2 hours and 20 mins to charge from 5% to 100%. That's pretty decent, isn't it?
It does charge slowly if you keep the screen on and use its multimedia functions, as I suspect the drain is substantial, but if simply on standby, mine charges reasonably quickly.

Ya, mine no longer charges from PC USB when PC is sleeping. When PC is awake the charging is way too slow. My old HD2 could charge fine from PC and this saves me from having to plug in its dedicated charger to power socket.
Hmm, im reading that most of you get a full charge, from 0%, in just about 1 hour. Mine is taking 2 hours, why is that? I've had the phone for a week.
EP800 charger maybe?

I believe you can pull from 100 to 400 mA from the USB port on a computer.
And the wall charger should put out at least double that. So ofcourse a charge will be slower when you can't pump as much juice into the battery as you can with a dedicated wall charger.
You can on some mainboards let the USB ports stay alive while the rest of the system is a sleep. But sure it's only logical that when you put your computer to sleep, so will the USB ports.
HD2 is able to get charged through USB when PC is asleep, but not XS. For those who're interested.

find a good cable and a good 1.5A-2A charger, the junk HTC gave us is something out of their "just include something" bin. I haven't even taken the stock charger out of its packaging. its good in a pinch when you must have a charge, but not worth using on a higher power device like the N9.
also, give a kernel like elementalX a try, it should enable faster charging..
anker makes some good self regulated (based on needs) multi port chargers, give those a try with some anker 1' cables.

After you change the cable you might realize that this won't solve the problem. Most of the times it works better if you simply reboot the tablet, the charging time will significantly decrease (~3-4 h depending on your kernel). Share if something changes.

Yeah that's not normal... I would now try the stock charger... That's what I use and it works fine... If that doesn't help then I'll would call Google for a replacement
I'll wait for 5.1 to come out and will take a decision then. Thanks for your input
it's not normal for this to happen, but i've seen a few threads where this does happen and it doesn't matter the kernel, charger or cables. sometime the device gets stuck at charging at less than usb 2.0 speeds. it doesn't happen all the time, but it's pretty crappy when it does happen. one suggestion was to unplug and replug each time you charge it to hopefully not get stuck with the bug through that charge session. when i do catch it trickle charging i just replug it. i generally charge in just over 4hrs for a full charge using a samsung note charger and cable.
I have been using the stock charger with a third-party USB cable (I needed something longer) and it has never taken more than 3-4 hours for a full charge.
Try using Ampere app from the play store to test different chargers and cable combinations. It helped me to eventually go with a iPad charger and a 20awg 1m cable which charges at an average of 1700mha which means a full charge of about 3hrs or less (stock ROM + ElementalX fast charge enabled)

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 S7 Edge can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
In 30 minutes of charge (with the Fast Adaptive Charger in the box) I got from 8% to 37% (from there to 100% it would have taken me another hour and 9 minutes according to the phone).
Kind of slow, to be honest. I know it's a bigger battery, but still...
(I also tried a Motorola QuickCharger 2.0 and it recognized it as a fast charger, but the results were the same)
Yeah not that quick tbh
Nothing wrong with that. 37% can get you 3 hours of constant use..
My fast charger isn't quite right I suppose. Di I need to turn something on. This is with the charger right out of the box.

Using a charger from my S5 way only a little more than an hour.
Sent from my SM-G935V using Tapatalk
I'm having charging issues with my S7 Edge. I received it last night and did a micro USB data transfer from my Galaxy Note 5. It took a couple of hours but the GN5 went from 75% battery to 71%. My S7E went from 57% to 27% and it was charging wirelessly. I've got it plugged into my laptop to charge right now and the device is draining while I'm using it. Any advice on what might be going wrong? I don't think it's the cable. I've got a fast charger but the outlet at my desk at work is behind me so I can't check my phone while it's plugged in.
So I just tried the Fast Charging again -> 1 hour (60 minutes) = +67% (from 4% to 71%)
Samsung Galaxy S7 Edge with it's original Adaptive Fast Charger from the box.
Yeah it charges pretty slow, I wonder if samsung can enable quick charge 3.0
Are you guys for real.
IPhone 6plus has a 2950mah and takes about 4 hours to charge. S7 edge has 3600mah and takes around 1 hour and 57 mind to fully charge.
Charger is pretty fast for the size of the battery, but my issue is that my battery is draining fast while in use. Thought Android "M" had this Doze Mode,
well even when not in use, it still sucks down battery like a long distance runner in a heat wave. basically to make your battery last you can make a call or 2. someone invent a SMART BATTERY. or a phone that runs on gravity
I have the samsung fast wireless charger and it doesn't charge fast. If I plug in the cable it says fast charging. If I put on the fast charger is just says charging. I did some research and they said in the battery settings there was a way to enable fast charging for cable and wireless charging... I only found it for the cable... Thoughts or ideas?
About 100 mins from 0 to 100 with included charger. Disappointed because it doesn't have QC3.0 when even a $400 midrange phone (the A9) will have it soon. I'll be even more disappointed if other sd820 phones have qc3.0.
So i tried charging today with my Motorola Turbo Charger (Quick Charge 2.0) and in 30 minutes it went from 9% to 43%, that means +34%.
Curiously, with the Samsung Fast Adaptive Charger from the box in 30 minutes of charge I got a 29% (from 8% to 37%).
I have the S7 Edge Exynos version.
can anyone try using iClever BoostCube 24W Quick Charge 3.0 to charge, its a 24w beast
http://www.amazon.com/iClever-BoostCube-Compatible-Charger-Foldable/dp/B019GQ6S2C
for me, 130 min from 5% to 100% with wireless fast charger (10W)....
On my 10w wireless charger I'm taking about 2H: 30m.. thats with the Samsung fast charger.. I have a 18w qc 2.0 that I should get today and will see if I can get a little better
I just did a side by side charge between my S5 and new S7 Edge on their stock chargers.
S5 started at 23%
S7E started at 26%
1hr 15min later...
S5 ended at 97%
S7E ended at 100%
So these two phones have identical charge times. Both phones had all apps closed.

The power supply would not be anywhere near 100% efficient, so what it is taking AC is going to be close to double what it is giving to the phone.

Yes, it actually is near 100% efficient. You're saying it's only about 50% efficient which is an absurd unsupported statement. My Pixel XL reads 18W~ just like this when it charges from 0% - does that mean it's not charging at 9V/2A? No, it's definitely charging at 9V/2A.

Except they don't hardly work worth a damn. Almost none of them work with QuickCharge, and none of them work with type C or power delivery.
Absurd? I did some quick googling to try to find the efficiency of a switch mode supply, it definitely isn't 100% so I decided to make it easy for the o.p. and give a 50% example.

not sure what device you speak of, but I'm talking about wattage energy monitors and all my watt meters work with me note 7 as they should... qc just means higher voltage and current, nothing fancy, and so it does show 9v @1.8A or so which is what its meant to do anyways.
Cmon people use some common sense.
The battery has a nominal voltage of around 4.4v fully charged. It has a capacity of 3500mAh.
These means a charge current of 3.5A is a charge rate of 1C which is fine. Even a charge rate of 7A would only be 2C.
As for the 9v, I GURANTEE there are some losses. It would have to convert 9v to 3-4.4ishV depending on charge current.
Let's say the battery is low and it's charging @ 3.5v or so as first part of the typical CC / CV charge cycle.
This means a constant current of X with a variable voltage which early on might only be let's say 3.5v on the voltage curve early on.
Watts = Voltage(Current)
18 = 3.5X
X= 18/3.5
X=5.14
So 5.14 Amps @ 3.5v would be going into the battery during this early on fast charge.
With a capacity of a whopping 3.5Ah, a charge current of 5.14Ah means a charge rating of 1.47C
Now remember, there are some losses from the conversion too.
So under 1.47 (probably under 1.3-1.4 with energy losses) C rating seems normal.
Personally, I wouldn't exceed 1C which is why I disable fast charge.

Yes, it actually is near 100% efficient. You're saying it's only about 50% efficient which is an absurd unsupported statement. My Pixel XL reads 18W~ just like this when it charges from 0% - does that mean it's not charging at 9V/2A? No, it's definitely charging at 9V/2A.
Except they don't hardly work worth a damn. Almost none of them work with QuickCharge, and none of them work with type C or power delivery.

Please read my post above. It is NOT charging at 9V. Feeding 9V into a lithium battery would make it explode.
It is being converted using some DC-DC converter so the battery gets fed around 3.something to 4.4v during the CC/CV charge curve.

Absurd? I did some quick googling to try to find the efficiency of a switch mode supply, it definitely isn't 100% so I decided to make it easy for the o.p. and give a 50% example.

It's probably about 95% efficient actually, which is pretty close to 100% in my book.
There's inefficiency in the battery however, since the phone gets warm when charging, right? And warm = energy being dissipated as heat. i.e. you have to put more than 3500 mAh in, in order to fully charge a 3500 mAh battery.
