[Q] How does the fast charge work?

So according to the advertising, these will give you 4 hours of movie watching time, with a ten min charge. How does that work?

It charges the battery faster.

Well that advertising is wrong i get 5-6 hours sot on %100 battery

I have tried higher amp chargers on other phones and it charges them faster but the charge also drops faster.

It doesn't happen on the s6 ofc, the s6 has special hardware and fast charging capable chargers for it, it isn't just a higher amp charger

I believe the ad is get 4 hrs of battery life time with 10mins fast charging and ultra power saving mode .

I don't know if it's 4 hours, probably is. All I know is it is very fast and 10 minutes gives it a great shot in the arm.

The fast charge spec can charge at 5v like normal USB, or 9, 12, or 20v
It'd be dc-dc converted in the phone to charge the 3.8v cell but at a higher current than if it were only converting 5v
The charger with it looks to only do 9v, my moto charger does 12 and I have a cheapo that claims 20v but I've not owned a phone that would negotiate that high yet.

This.

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% ?

Would like to know this too

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

Slow charging? Please help!!!

Hi guys i have a little question my S6 charging very slow yesterday it was good but today when plug in the USB cable to charge it say 30% 4 hours to charge usually it is 2 hours 30 min, if i unplug the cable en plug it back in than it is normal 2 hours 30 min again but after 1 min it jumps to 4 hours if i try another cable stays the same. but i was looking for a fix some say if..
if you go to dialer app and type *#9900# and you get an list on the bottom of the page it says “Low Battery Dump” you can turn it on or off does some buddy know what this is and what does it do
I am on the latest beta 6.0.1 marshmallow Galaxy s6 G920F

I already had to change 3 cables because of fast charging not working.
Maybe your spare cable is defective too?
BTW, even 2:30h hours is too long. Normally a S6 takes 1:20h to charge from 0 to 100...

I changed the cable to but still the same if i pull down the notification panel its says use original cable and charger but is the one out of the box its very frustrating me and it says 4 hour to charge if i pull out the cable and putt it back in its good for 1 min and i get the message again use original cable and charger and again 4 hours do you guys think it is the cable because if i put the phone in fast charging mode in battery settings its working very good no issues only with normal charging gives the message use original cable and charger

it took 4 ours to fully charge from 30 to 100 % fast charging off.the weird thing is if i putt fast charge on its doing very well 50 min from 30 to 100 %. but the thing is i dont want it ti fast charge because the battery life will be bad if i use it every time or am i wrong ????

I had the same issue. Does MTP work when you connect your phone to your computer? If not, your S6's USB port is probably dead.

Hi, I had same problem. My S6 needed about 6 hours to charge. When I tried search forums etc, I tried to to push usb cable into charger and I found out, it is possible (I think, I inserted as was possible)... So now I am charging in cca 1,40 hours...

I think you shouldn't worry about fast charge unless you plan to stick with this phone for more than three years.
Also, fast charge is faster than normal only in the beginning of the charge cycle. As you get closer to 100, it slows down to preserve battery life.
Fast charge is made to give that fast boost when you're almost without battery on the go.

i do not know for what time i want to use this phone mayba 1 year or 2 but i think if you fast charge the cells in the battery die faster is this true or am i wrong ??

i am charging my phone now fast charging disabled it is on 50 % and it says 1 hour and 27 min i just dont get it sometimes it says 4 hours to charge and the other time shorter i just dont know what the problem is can it be that i dont pushed the usb cable not far enough in the charger that its taking to long to charge ?? can this be the problem or what its very strange

you need a 2amp charger

Battery lasts longer after normal recharging than turbo charging

Hi,
I noticed that when I recharge it with a charger that is only 650ma the battery last much longer than with turbo charger that came with the phone.
Even in standby after recharged it takes one hour to consume only 1% but after turbo recharging it takes about 10 min to drop 1%.
Is there anyone experiencing something like that?

Funny it is.... The case is opposite for me... Although I use Transomart QC 2.0 charger. My battery lasts longer when I charge it with quick charger compared to standard 1 Amp chargers.

That´s so weird.
I am preparing a comparison to figure out what's happening.

It happens the same here. I've a Aukey turbo charger and the battery drains faster

I also got Aukey and it's the same

There's no way to actually know the charge (in mAh) of a battery without draining the battery. The way that phones estimate the charge is by measuring the voltage of the battery. Quick Charge 2.0 (supported by the Moto X 2014) uses a higher voltage to charge the battery faster. This can make the battery hit max voltage before it is actually fully charged. That is why Quick Charge always advertises how quickly it gets to 80%. To get to full charge (not just when it shows 100%, but when it is actually fully charged) will take about the same time as a standard charger.

Heat and Turbo charge destroys your battery.

if i turbo charge , my phone will suddenly die when it's between 10-20%. W/ regular charging I get sudden death at 6-8%

i use a moto razr 850mah charger and solved the 8% sud power off, took 2 charge cycles from death to 100% leaving it overnight. Now battery works as it should

.
As I've been reading around (can't recall specific scientific data), the faster you charge the battery, the less capacity it can hold. So it makes sense that it lasts longer if you charge it slowly. I don't know how much would be the difference tho.

It is normal in my opinion. Slower charging is also healthier for the battery and usually will last longer

Has anyone ever used a wireless charging pad with the phone. I bought a stick-on one from amazon and it charges fine,,,slower but fine. However, I noticed that it tends to get suck at certain levels and if I take off the wireless charger at say 89 percent,,,it takes less than a min to go to 100 percent charged?

Recomendeed is charge with Motorola original charger of this device, i mean 1150mAh dual port charger

Anyone here with experience of using Motorola's Turbopower 15 wall charger? I'm thinking to buy one, because waiting for 1 hr to charge to 100% is quite annoying.

Fast charging not working.

Pretty much as the title says. My device says its fast charging but it takes hours to increase only a few percent. Its charging faster through my battery bank with 10.5W charging then the super fast charging

Do you have selected fast charging in battery settings?
if yes and not fast charging, try to restore factory settings.
for last, its the charging port problem, i have the same at mine 3 months ago.
in warranty i changed de charging port and a new battery.
