Galaxy Charging Current app as for me shows only the maximum capability of the cable you use to charge your phone. I`ve got a couple of wall changers and car chargers as well (bought all for SG4). Stock Samsung charger is currently my only wall charger with true 2A output whereas some chinese chargers that says 2A output gives only about 1200mA as well as my Samsung counterfeit charger.

Luckily car chargers that i have are better cause they give 2A (1900mA showed in app) and in that case i could check it cause i powered them from regulated power supply that shows what amount of current that is flowing to the device (and there was a difference on "good" and "bad" cables). From the voltage (12V car charger) and current (0,35-0,75A at 12V) that my regulater power supply showed depending on the charger and cable i counted the power from 4W (for "bad" cables) to 9-9,5W ("good" cables). Testing different car chargers and micro USB cables shows that the cables are the main problem.

Concludes this app shows/can determine the "quality" of the cable of course if the charger is "strong" enough" cause when it`s not then it shows the max output of the charger if cable is good quality :D

What... the f***... We suddenly must be concerned about a freaking cable, that doesn't show any signs of defection?! WHAT THE F*** !!!!!!!!!!!!

The Samsung stock charger (2A) is in my wall, at home. Connected to it is a BlackBerry microUSB cable of 1.8 meters.

The stock cable sucks. It's too small. Besides, the connector si too easy to unplug from the phone. I'm not gonna use it.

Otherwise, I have another 1m cable...

-----

I never had to be concerned about cables in my life. Except for this one time I owned a Galaxy S2 which... as you may probably know... requires a specific charger (+ cable?) in order to deliver 750mA (OH WOW).

I am super confused. What the flying f***... :headbang:

---------- Post added at 11:57 AM ---------- Previous post was at 11:55 AM ----------

So. I am now on Phoenix ROM + Perseus kernel. I can alter charging currents to the extent where I have no idea what each thing does anymore (fml).

Tell me, how to test whether a charger / cable is working properly. Cut the charger part, I know it's good - it can't not be good, ffs. (Engrish)
[Android Software Development] flash608:
Personally i like the stock samsung cable ;) but yeah it could be longer. I had an SGS2 as well and the problem with chargers comes with it. This was the time that i bought different cables and most of them were ok (not all cause not every one worked with data transfer to PC) and chargers (most of them could produce current up to 1A so they were ok). In SGS2 max current was as i remeber around 750mA.

Things have changed and now we have SG4 with "fast charge" feature with 2A max (1900 to be precise). Most of my chargers can`t produce that amount current/power so i bought new one but then i was suprised that even if i was sure that charger could handle this amount of current it cant charge my phone phone fast ... it showed that cables matters.

I bought cables from dx.com, focalprice.com but none of them works with 1,9A. In my country there`s a auction site "allegro.pl" from where i get some counterfeit on popular brands like HTC, Sony Ericcson, Sony, Samsung and what`s funny only Sony counterfeit cable is well made (it`s thicker than the other cables) but it`s similiar lenght as stock Samsung cable. Also i got some old Sony Ericsson cable that is around 2time longer and it`s ok (1,9A) but can`t find it on net to buy some more :(

In time having SGS2 i did use a "dice meter" on one wire to measure the true current that flows from charger to phone but it means removal of insulation. If you have universal meter you could cut it and measure the current while charging... but you have to cut your wires.

As for me this app shows to be very usefull (i don`t have to cut wires to check "quality" of cables) cause as i wrote before it shows the max current that the cable is capable of if the charger is capable of producing 2A current.

So if you want to know if your cable is good then use stock Samsung 2A charger and test it with different cables (mark your cables which is good and bad) and if you want to test your other chargers (wall or car chargers) then use stock Samsung cable or any cable that you are sure can output 1900mA from the first test :)

And one more thing... there`s no one to blame on the cables quality. They worked well but the time have changed and they are insufficient. The same thing is with audio cables etc. Formerly we did use smaller diameter conductor and it was ok for that times now we use thicker cables if we want better quality.

P.S. sorry for my english.
[Android Software Development] Formhault:
Oh... you're absolutely right.

Until now, I haven't faced such problems because the current flowing through the cable could never be more than 1000mA as I never had a charger capable of giving 2A and a phone that was capable of receiving >1A.

2A is twice the current of 1A... obviously. In order to be able to conduct such current, the conductor needs to be thicker (or better).

In this case, the Samsung stock cable is good because... it's both thin & capable of conducting high currents.

The other 1.8m cable is not as thick as the HAMA cable I owned a long time ago. Perhaps the HAMA one would be better...

Anyway. I get what the problem is now. It's not a problem actually. As you said, manufacturers can't be held responsible for not providing cables that can conduct very high currents. But some indications such as max. current should be printed on the cables... :(

Will try the cables at home.
[Android Software Development] flash608:
I had marked my cables like that:
[Android Software Development] Formhault:
Well... It won't be too hard for me to remember which is which. One is 1.8m long, one is 1m long, the other is the Samsung one which is white (yellowish, actually)...

Well. I'm just hoping the 1m long cable is capable of delivering 2A. It's a bit thicker than the 1.8m one. If this proves to be right... well, f***. I just bought that 1.8m long cable just for that reason : plug it in wall charger, leave it by my bed, forget about it. :(

[Android Software Development] Formhault:
I used the 1.8m Blackberry cable (with the stock Samsung 2A charger) overnight and... here are the results.

Charged from 10% to 100% in ~3 hours and a half... (saw logs in Battery Monitor Widget).

At the moment I plugged in the phone, Galaxy Charging Current showed Max & Avg : 1800, Now : 1698.

What the hell... It's supposed to be fully charged in less than 3 hours :eek: :crying:
[Android Software Development] reS28raM:
Please don't use Perseus' overcharging feature until you are really sure that the cable is good. ;)

After attaching the wall charger and pressing refresh the two main values must both show 1000 assuming you are on S3.

If that is not, try to unplug and plug again the cable and press refresh again. If both the above values changed, you have a false contact on that connector, and this seems to be the problem...

Try this on both connectors, you'll find that the defective one is almost always the microusb one.

Now you must change the cable finding a good one, and exactly at this point the nightmare begins. :eek:
[Android Software Development] Formhault:
I have a Note 2. With a 2A charger (stock)...

Max / Avg values show 1800. Now shows 1698. What does this mean? That the cable is good?

I did not change anything charging related in STweaks. See the attached image.

[Android Software Development] reS28raM:
It seems perfect to me. :)

Now value seems to be a binary value which changes on different devices, you can safely ignore it.
[Android Software Development] Formhault:
Now showed 1698, which is 2 less from the DCP AND MAINS CHARGE CURRENT (1700).

Max and Avg showed 1800, which is exactly DCP AND MAINS AC INPUT CURRENT...

So... charging at 1.7~1.8A from 10% to 100% took 3 hours and a half?! That doesn't look perfect to me. It shouldn't take longer than 2 hours in my opinion :eek:

Yes, I used previous version widget. I use Nova launcher, before and after the update, I use this app launcher. Nothing changed.
[Android Software Development] flash608:
SGN2 has got a 3100mAh battery. You are charging your phone while it`s ON that means it is using energy to work so forget about charging times like 3100mAh / 1800mA = 1,72h = 2h 12m

Also you should know how does battery charge cycle work --> http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries so as you see charging isn`t a simple thing. It`s even not so simple when charging AA/AAA cells.

Least but not last when some device says on it`s description plate that it has 2A current input then it means it`s the max. input current but it`s not constant, it changes during charging/using. At our houses (daily life) we don`t have many if even any devices that are working with constant current. 99% of home use devices are voltage constant and the constant current devices you will find in industry (e.g. constant current engines).

Don`t know what`s like with SGN2 but on SG4 during some latest update Samsung has changed values of charging current in kernel from 1900mA to 1200mA while screen is ON, when it`s off it`s 1900mA.
[Android Software Development] Formhault:
I know. I know. I know!

A 3100mAh battery will not charge in 2 hours because it will not charge at 1550mA per hour in every second throughout the duration of charging. It starts with small current, reaches high current, and as the battery gets filled up, the current input drops.

Anyway. My samsung 2A charger + a Samsung original cable (it's kinda short, though) equals... well... see for yourself :) http://pastebin.com/1z5Vf5EB

Problem solved. F*** cables. :(

[Android Software Development] jproy12:
Just got my S4, and I've used the Galaxy Charging Current app pro (that I also bought) to find out how much some of my chargers at home can charge the S4, and I see that with the stock charger and stock USB cable that came with the phone, even though it says it can charge up to 2.0A, I only see 1200mA with the Galaxy Charging Current app, yet it fluctuates between 1900 and 1200, depending if I turn the screen on, is that what it's supposed to do?

I've also tested a blackberry playbook charger, which is 2A and it also does the same thing as the stock charger+USB, fluctuates between 1200mA and 1900mA. Is it supposed to fluctuate between the 2? I'm assuming it is for when the screen is on or off.

Just looking for inputs!
[Android Software Development] Formhault:
Yes, it's nornal.

The current that reaches the battery will be 1200mA when you're using the phone because the rest (~700mA) will reach the actual phone for usage.

When you're not using it, all the power is going to be directed to the battery, as the phone does not need power since you're not using it to play games or do anything intensive.

[Android Software Development] jproy12:
That's what I thought, thanks for confirming this, so I can now say that the blackberry playbook charger is good for the S4, putting 1200-1900mA to the phone no problem, just need to find myself a good car charger that will charger more than 1000mA.

Griffin chargers are good.

Sent from hyperspace
[Android Software Development] RDI:
Are they Apple standard or Samsung standard? What I mean is when you go into Setup /Battery does it say "Charging USB" (std/slow charging) or does it say "Charging AC" (fast charging /only from Samsung standard charger)
[Android Software Development] Formhault:
The Griffin chargers? I have no idea what standard they are (by the way, Samsung complies to the standard, Apple... made its own, sort of), but I do know this : they charge as AC, not USB. My girlfriend has one (5V~1A output) and it charges an iPhone 4 and a HTC Desire S just as good as a wall charger :) .
[Android Software Development] RDI:
Samsung has its own standard to activate fast charging. Apple does not use the modification that Samsung does for fast charging.

There are several ebook readers that use the same type of charging system as Samsung and will not fast charge from even a iPad charger.

There does exist a Dual Standard /Dual Port Fast Charger. There is a AC version and a cigarette lighter version. They are at least 2100mA.
[Android Software Development] Formhault:
Well, the Note 2 has a chip which knows if a cable is good or bad. If it is bad (99% good), it will reduce input current (boo!).

The charger... outputs 2A and that's that. Same as for Apple chargers. But of course, if a phone is programmed as such to detect wether the charger it's connected to is good (has quality controllers & parts) or bad (lacks a specific controller that is otherwise required and included by quality OEMs)...

Erm... Griffin chargers?
[Android Software Development] RDI:
The "Samsung" Standard to activate fast charging looks for the data pins being shorted with a certain value resistor. Apple does not do that. The only factory making Dual Standard chargers is Avantree. Here is a link : http://pages.ebay.com/link/?nav=item.view&id=251320687965
[Android Software Development] Formhault:
The standard we're talking about... applies to the chargers, not the cables, right?

-----

I thought Griffin chargers are excellent, based on a number of reviews and my personal experience (although... not with a device that draws more than one amp).

So, chances are that if I plug my Note 2 to a Griffin charger that outputs 2.1 amps... it won't charge at full speed?
[Android Software Development] RDI:
Correct, it applies to chargers. Although, I have heard of people making a "Fast charge" cable.
[Android Software Development] jproy12:
I just saw this charger:

http://www.amazon.com/ACC-48181-301-Blackberry-Premium-In-Vehicle-MicroUSB/dp/B0089QK4NK

http://www.ebay.com/itm/NEW-ACC-481...S_Cell_Phone_PDA_Chargers&hash=item19e0085123

It seems like it's made for the blackberry playbook, and according to reviews, it has an true output of 1800mA, which is just short 100mA from our OEM S4 charger. Given the fact that I tested a "Playbook wall charger" and it worked fine on my S4, outputting 1900mA to my phone, I may give this a shot, since the Playbook calls for 2A, so it's basically asking for a similar charging as the S4.

I test many cables due to slow of chrging in my sgn2, Some new cables give me 500ma and other even new give 600ma, the best one is showing 1300ma.

Today finaly I got the best cable at low price ~$4.5 even made in china, 1 meter tall but thicker than usual,1800ma become standard for every test.
[Android Software Development] djcmn:
I tested a few USB charging / link cables. Interesting thing is I bought a cheap dual USB AC charger ( Just Wireless at Walmart) that is rated at .6 amp per port or 1 amp rapid. This app reads it as 1900 mA with its own supplied USB cord. I tried the GS4 cord AND the GS3 cord also and they all read 1900 mA off this charger. The same holds true when I tried all 3 cords on the genuine Samsung S4 Charger. The GS3 cord says 360 off of a PC USB port and the other 2 cords say 460. I don't think this is really telling the actual draw but rather just sensing the resistance across the data port and identifying that way. It isn't just this app that does this. Current Widget does also.

Is this an issue with the phone or the app?
[Android Software Development] abmantis:
It is normal that it is not reporting anything in Maximum. The system does not have the info. Are you willing to help me in trying to improve the support on the S4?

What is the rated current of your charger? Also, do the values change when you move the cable and the phone?

Do you have a small microUSB cable that you could test with? Like the ones that sometimes come with digital cameras.

Are you willing to help me in trying to improve the support on the S4? - I'll do what I can.

What is the rated current of your charger - Factory Samsung charger output: 5.0V - 2.0A

Do you have a small microUSB cable that you could test with? - I do have a shorter cable then the factory S4 cable that I just tried. It's about half the length and checked the app again and still shows 1200 (with no max).

I've also noticed that if I turn the screen on, enter my pin and then quickly go to the app it may or may not show 1900, but as soon as I press refresh it shows 1200.

Does anybody know if its safe or not to "ignore unstable power detection" in STweaks? I tested it and it fixes the problem, I get constant 1000 charging current all the time with the ignore option but I am afraid of leaving it on so not to damage the phone. Without this option, the current always changes between 100-600 on average. Im on i9300 paid version of current app.

I just woke up today and noticed that it's taking more than 5 hours to charge! I can't believe that this nightmare has returned on Note 3 also!

[Android Software Development] abmantis:
What Note 3 model/variant?
[Android Software Development] Benoob:
Thought I'd update with my recent findings. I have the same issue as many users here with unstable charging current. I have changed Chargers and cables but still the problem continues. I recently tried connecting the USB cable to the phone, but this time I kept pressure on the cable towards the phone while app is working and interestingly enough, as long as I keep pressure, the charging current stays at 1000 as it should. If I just let go of the cable, the charge goes back down to anywhere between 300-800. If I let go of the cable very gently, sometimes the charge will stay on 1000. I can now get decent current almost everytime if I apply pressure and release gently as to not rattle the connection between the phone and cable. This might not work for everyone but for me it works. Btw I'm using i9300 with Temasek cm 4.4.2 with Temasek kernel. Maybe someone can try and see if it's the same for them. Hope this helps someone, Happy New year.

After I've read many posts and threads about current max, average and now

I'm still confused how it actually works

I have Note 2 N7100 international, this app works, but I still don't understand

I got two chargers and a power bank

Note 2 stock 5.0v 2.0A

Xperia x10 stock 5.0v 0.85A

XiaoMi (output spec 5.1v 2.1A)

I plugged my note 2 on Xperia charger it shows

max = 1698

now = 800

average = 800

Note 2 stock charger

max = 1698

now = 1500-1800

average = 1500-1800

Xiaomi power bank

max= 1698

now= most of time 900, sometime 100-600, sometime 1000-1200, sometime jump up to 1800

average = same as now

I don't understand this, does that mean even if "now" and "average" current is higher than max, ur phone is still charging at 1698?

mind to explain how it works? like how the current changes in different situation? during screen off, in use, blah blah? :confused:

just saying that I can confirmed charging with note 2 stock charger is fastest at 1500-1800 "current_now", still testing the charging time for xperia charger and power bank though
