Galaxy J7 Pro comes with a 1.55A charger.
But do you guys know if it's the input limit of this mobile or it supports more than that?
If anyone knows about this then please clear my confusion.
Thanks.
You can charge it with 2 amps but don't try with fake ones. I am using tab2 charger (2A) and it takes 1.5 hours to charge without any heat. I must warn you, it is not safe to do, it might enlarge your battery. If you don't have an emergency situation, stay with 1.55.

Hi. I'm new here but not new with Android and S5.
I am wondering if anyone else tried to measure the Bundled S5 charger performance. Anyone?
I got my S5 on the first day it was available locally. Then I tried to measure its charging and was surprised to see that the voltage was much higher than usb specs. I am wondering if it is still safe to use 5.6-5.7V charging mobile phones. I think 5.3v is still on the safe side, but I think 5.6v is stretching too much. I'm guessing Samsung used 5.3v to hasten charging a little bit (A x V = W), but was also surprised that S5 saps only 1.75A even though the bundled charger is rated as 2A @ 5.3v.
I know that the charger should output less than 5.3v when a device is attached because of the power load. But it seems that is not the case.
I haven't used my S5 charger frequently, I still often use my S3 charger and my powerbank which are only giving out 5v.
I am asking here first before I go to Samsung Store and try to have it replaced. I don't want to waste effort going there if all S5 chargers are the same anyway.
I am unable to directly post links, so please see the attached image and the youtube video with the video ID.

Hi, so.. I forgot my charger at work.. and everyone around me use iphones and I have to charge my phone
I found an old samsung galaxy 1 charger, and so far it's charging pretty good..
but I want to make sure that it's safe. do you guys know if using a samsung charger can do any damage to my battery?
I also have dorimanx kernel forcing fast charge mode.
thanks in advance.

Nope, it's fine. It might charge slower, but the voltage will be the same. A non-android compatible charger will only charge at 500mAh due to the way Android determines USB vs AC charging, that's really the only difference you'll ever see on such a charger beyond the capacity of the charger itself, which would just manifest itself as slower charging.
Hi guys! I just bought a Note 4 a couple weeks ago and I was wondering if the Adaptive Fast Charger would work on the Note 2014. Haven't tried it yet but I was curious as to whether anyone else has.
Thanks!

It will work, but it won't charge any faster than the original charger.

I own both devices (Note 4 + Note 10.1 2014) and can confirm, that the charger works but not in "fast charge" mode.
Unfortinately the 10.1 charges quite slowly to put it politely. I was hoping that it would at least be slightly faster, although it should be because even on the low power mode, the new base has a slightly higher output.
I also have the Note 4 and Note 10.1 (2014 edition). I can confirm that fast charging doesn't work. Maybe someone knows but I thought an earlier version of Android had the option to turn on fast changing. I assume that it's a function that needs to be implemented at the kernel level.

How could you tell if it in fast charge mode or not?

Well, first of all, it does not charge any faster then normal, at least not significantly enough for me to notice. I have to admit, I did not a test with a stop watch.
The second thing is that when you connect the fast charger to the Note 4, there is a fast charge notification shown in the status bar for a view seconds. This is not the case for the Note 10.1 (2014).
From what I remember with my Asus Transformer Infinity fast charge could be be turned on using Trickster Mod. The kernal has to support it of course.
The Asus units use 15v for charging. If you somehow can trigger this mode on the charger, which someone succeded to with his Iphone, the Note's voltage regulator just will transform 15 instead of 5 volts down to 3.7v, the excess energy will be transforned into heat, and the regulator may fail.
I have a Note 10.1. I just charged it in lightning fast time to full charge. I used it for about 20 minutes. Then the indicator dropped to half and now it indicates dead after a very short period of time. Not sure if the battery is fried or if the software is freaking out. Ive been having charging problems before. Attempting to charge enough to do a factory reset to see if that solves the charging problem. If not - battery replacement.
I never had to cope with a lithium battery, which lost much of its capacity. But with most battery types a huge loss of capacity means that the battery charges from empty to full in no time, and back to zero in no time during use. The voltage range stays normal, thus the battery level should also reach up to 100%, which equals 4,0 to 4,2v in this case.
A battery seemingly no longer reaching full charge is a problem with the Android Coulometer. There are apps which seem to be able to fix this bug.
A similar, more popular Coulometer bug are battery level fluctuations. These aren't that simple to fix, probably only factory reset or the unbricking procedure help. But this bug is self-healing over a LONG time. We're talking bout months.
Thought you might like to know, the original Samsung charger works well, but to achieve maximum results you need to use a 2.5 Amp USB charger. This used to be stated in the Samsung+ app. This almost doubled the speed of charging the tablet. I know that this isn't quick charging, but it's worth knowing.
hey guys i have tow questions and i really hope if some one can help me
1. we all know about the s pen feature that allow us to select text by pressing the s pen bottom then an option window comes out but we cant use it every where ..... so is there any way to make it work every where or at least in more apps like moon+ reader
2. we all knew about charging cover but in note 4 there's (fast charge) so does these cover support this or not and will it harm the battery or not
2. There is no way that wireless charging can support fast charge. Wireless charging usually outputs 0.6A curent, "regular mode" Samsung charger outputs up to 2.4A and goes even higher in adaptive charging mode: higher current and voltage up to 9V. It possible that fast charging will shorten lifespan of battery but they are easily replacable. If there were no effect on battery Samsung wouldn't leave us a choice to enable/disable it. (imo)

think you but i meant the recharge cover the one that comes with battery inside th cover
when you use this cover your phone will be charged by the cover so my question was will this covers support fast charge
Hey all, haven't been able to find an answer for this. So I'll open a new thread. Now the question. The phone seems to take a long time to charge. Is it possible for me to use my Note 4's quick charger or can anyone recomend a faster charger for this phone? Charging it with Note 4's 2a charger wont damage the battery? Thank you.
I use a 2.1 out and it charges in about an hour and a half
Charging isn't fast and it seems that if the phone gets warm, it draws less power then too - so on a warm day, it can feel like it's taking years.
Would have been nice to have had wireless charging support and/or turbo charging, but alas not.

Doesn't the phone support quick charging? But Huawei haven't bundled the appropriate charger?
Doesn't appear to. I've got a Qualcomm Quick Charge 2.0 adapter and it doesn't seem any faster, nor say fast charging.
There's a quirk, when the battery shows 100% it actually still keep charging for another 30 minutes. All tests showed that it took 3hours+ to fully charge it. So quick charge my ass.
So just to update, I have tried charging it with note 4's fast charger and it charges the phone from 20 to 100% in about an hour and a half. Which imo isn't that bad. With the included charger, it took me around 2 and a half hours... Huawei really should have included a charger with higher amp, 1 is way to low.

It's sadly very common for phones to ship with poor chargers (1A and even lower), but then again - some phones these days come with NO charging adapter, assuming you'll have a ton of them anyway.
I use a 2.1A 5V charger, but I've tried the faster ones (that can output 9V) and it doesn't speed things up, so while it can charge faster with a better PSU, it won't ever charge as quick as many other flagships. Mind you, has the G4 been given full support yet? Likewise, the Z3 is down as supporting Quick Charge 2.0 on Qualcomm's website, but then turns out to be only some variants. Makes me wonder if the Z3+ supports it in every guise.
Not sure what the reasoning is for devices that could support faster charging not actually allowing it, especially if the manufacturer could profit from selling faster chargers separately.

I read an article about Huawei declining fast-charge for "battery-purposes" so it can have a longer life cycle. But i think Huawei made an exception about the Huawei Honor 7.
I had an Samsung before and never had problems with fast-charging whatsoever.
My P8 was full in about 2 hours with an 2.1 A charger, while my Samsung Galaxy Mega 6.3 took 1,5 hours.
the screenshoot took from Huawei P8 & P8 Max Launching Event 2015 said that p8 has quick charge at min 21.30 but they didnt talk about that in the event

Here's a quick charger for the Huawei P8 : http://www.amazon.com/Adaptive-Charger-Charging-voltages-charging/dp/9713256832
I did not buy it, but it says it charges at 9V 2.1A

I think this adaptor isn't safe to p8max.. I will try another charger but only 5v with higher amp that will be safe for sure
Now i charge with stock from 3%to100% in about 2.5 h and the phone didn't tell me to remove charger for more half ahour!!

I dont know, its 9V 2.1A, so it is quick charge. But i dont know if it is for MAX. I can charge fast. maybe 1.5h/2h?
