Well, first because when I use a USB extension the current is so low that it charges like 10% in 8 hours (once again, this does not happen in another HTC smartphone, with the same charger+extensions).

Second, because even when using the stock cable I don't like to wait 4 hours to be able pick the phone and go out (usually it takes only 2 and a half hours, but sometimes....).

Understand that each person has different habits and needs. Maybe for you it is nonsense that a person wants the phone charged fast, but for me it is nonsense that you want your phone to charge slowly. Right, if I'm spending a whole day at the desk I don't mind the phone taking the whole day to charge, but that is not always the case.

I've got an old Samsung wall charger (think from my Omnia HD days) with an output of 0.7A. That charges mine in about 2.5hrs from dead. Only use that coz I've noticed that charging from USB is majorly slow

Re: Check if your device is charging at the maximum current

Interesting thread.. Thanks for this. I've checked it out and my current_max is 1000.

<sent from my Nexus 4>
[Android Software Development] abmantis:
Your welcome. I just hope we could find the reason for this problem.

If you don't mind, please keep checking the current_max periodically to see if your device always charges at 1000.
[Android Software Development] Oomahey:
I always check your app as soon as I connect my phone to the charger. I ensure that the current_max is at 1000 before leaving the phone alone to charge in peace.

I usually wake up with just enough time to fully charge the phone before leaving for work. So, your app is a God-send. :good:
[Android Software Development] supreethms:
Does this apply for USB charging too??

The optimal USB charging value in my phone was 450..

I changed it to 700..

I see a little difference in the rate of charging..

has it something to do with it??

sorry.. noob here.. and i need info..

:(
[Android Software Development] delsus:
For me using the stock plug and cable I was jumping around between 460 and 900, using the stock charger and alternate cable I was contantly at 460 using the stock cable and alternate plug I was at 900, using alternate cable and plug I was at 1000.

If you aren't charging at 1000mA try changing the plug and cable that's where my problem was.
[Android Software Development] abmantis:
Does it always shows 1000? Or does it sometimes shows less than 1000?

By the way, sometimes it shows 1000 when I connect the charger but after some time, like 5 minutes, the value decreases.

Yes, you can check the charge current both in AC and USB. Connect the cable and check the current_max value (or use the widget), and see if it is set to something near 700.

How did you set it to 700 on USB? Using a custom ROM?

Interesting! So, the problem is the default charger?

I will try that when I get my hands on another charger :)
[Android Software Development] delsus:
From what I have seen it is, this was also on stock unrooted ELLA, so it's nothing with custom roms.
[Android Software Development] kryptk:
cool little app :P
[Android Software Development] Oomahey:
Install Siyah kernel, then STweaks and check "Ignore unstable power" under the Power tab (You can always go back to the stock CM kernel by reflashing the ROM without wipe). Check what the charging current is. But be aware that this might damage the phone, though. I have been using it like this for two days now...nothing has happened till now, thankfully...*fingers-crossed*
[Android Software Development] AndikaTedja:
I dont see power tab in my stweaks
[Android Software Development] Oomahey:
Look under Misc. If not there, check other tabs as well. I'm on Adam kernel and STweaks has a Power tab under which I find this option.

For the uninitiated, STweaks has different layout for different kernels.
[Android Software Development] abmantis:
I don't think that Siyah kernel has that option. At least not on the latest version.
[Android Software Development] sirdigitalpython:
Interesting... Just downloaded and tested... With rooted stock rom .. Stock charger and cable... Using official s3 charging cradle I can only charge at 600ma... Remove the dock and It gets to 1000ma is this by design of the dock...(I doubt it as the dock is rated 1A so should work right) Or a fault? I assume the stweaks and custom kernel fix will rectify this too... I find my phone runs hot with custom kernels and prefer to stick to stock if possible... Anyone else have dock with same?
[Android Software Development] Oomahey:
Oh. Thanks for letting me know, mate. It had been some time since I have used Siyah. Sorry for sending all on a wild goose chase! :(

At least, install Adam kernel, check "Ignore unstable power" in STweaks and check with the charging. (At your own risk, of course). :)

[Android Software Development] syamsoul:

Samsung Smartphones & Tablets will only FastCharge (Charging AC, see battery/settings) when using a "Samsung standard/style " charger, no matter how much mA it is. A "apple standard" charger, even a 2100mA, will slow charge (Charging USB) a Samsung device.

[Android Software Development] syntax1993:
I get 1000 using the stock cable (wall charger) and 460 using USB. With a 3m cable (non-branded), I get 100 using the wall charger and 260 using USB.

Could it be the length of the cable or is it just broken?
[Android Software Development] abmantis:
I think it is because of the length of the cable... a 3m cable is a long USB cable :P
[Android Software Development] syntax1993:
I know it's long. But could it take away 9/10th of the amps?
[Android Software Development] miwanr:
Almost every time I get this GCC value with stock cable and charger which has output 5.3V 1A.

But I have one question, is it save to use that charger regularly? As standard charger has output 5V 1A.

Thanks for the app it's just brilliant. I To hit that refresh button a million times. With regards to a much earlier post showing the *#0228# code what does the quick start red button exactly do?

Can anyone with an S4 report if the application works? Also, please post the model variant (or the country/carrier).

Thanks.

CurrentWidget does not work on most Galaxy S3 variants.
[Android Software Development] miwanr:
Working on S3 international.
[Android Software Development] abmantis:
But it always show 466 (or something like this) on USB and 999 on AC, right? The values never change.

That's the equivalent to Current Now in Galaxy Charging Current, and is mostly irrelevant.
[Android Software Development] KryptosXLayer2:
It works on my S4, ATT I337, but I don't see the three categories, just Now and Average - Maximum displays nothing. Also, when not connected, it still reads last value even after hitting refresh. Can't wait to see this thing with a really nice skin on it to "pretty" it up! I'd be glad to help with that, but I have no idea what I'm doing with apps and widgets, just themes on phones, haha....

Great app and thanks for being the first and ONLY (as far as I know) amp meter for Galaxy phones!
[Android Software Development] KryptosXLayer2:
Also...... the widget just does not work at all.... I see the Refresh button on it, and nothing else, no display, no numbers, nothing
[Android Software Development] quark_star:
Another S3 owner affected by this issue :(.

I've tried a few USB cables with the stock charger, all producing unstable results. Using a stock S2 one piece charger (0.7A) gives me a stable 900mA every time i plug the phone in, which is at least reliable.
[Android Software Development] abmantis:
Thanks for the report! I'm not sure what is happening on the S4, but I'm trying to figure out (I don't own one so it may take some time :silly:).

Also thanks for offering help on theming. I'll think I'll keep the app's theme for now, but I'll try to give the widget a little love :laugh:

I've also used a Sony camera cable and a Samsung cable (from another device, not and S3), with non stock chargers and they work very well. I have to try them with the stock charger to see what happens.

But yeah, the stock S3 cable sucks hard.

I just tested it on my s4 from Sprint. It doesn't seem to work. Even when the phone is unplugged and discharging the app shows +.455. When I plugged it into a wall outlet it showed +1.9, then a short time later it showed +1.5, I was using my old charger which has a 1ma output. It seems all the app does it detect USB/AC charge and shows the max for that

Woah almost 2 amps from a USB 2.0 port!!!!
[Android Software Development] reS28raM:
Abmantis, why don't use /sys/class/power_supply/max77693-charger/uevent for your tests? It is much more explicative.
[Android Software Development] abmantis:
Only because the other files I use have a simpler and direct value. And it is easier for the app to parse that instead of the uevent file.

By the way, latter I've been using a small (20 cm) Samsung camera cable with a 2 meters extension and the stock charger and I get stable 1000mA every time! And this is a cable longer than the stock one, but works much better.
[Android Software Development] reS28raM:
Yep! I made a test with a cable from an USB Passport hard-disk, a very short one unfortunately, and your app: the charging speed doubled!

Today I'll check the HDMI output to my tv-set, I expect to see a visible increment in the output's quality only by substituting this stock cable.

Not only charging is affected for sure... but all services relying on it also. Thanks for spotting the problem in a measurable way.
[Android Software Development] kevlarman:
The phone is probably detecting a slight voltage drop with cheap (or longer cables) and adjusting the current accordingly.
[Android Software Development] reS28raM:
Yep, but the cheap cable is the one supplied by Samsung with SG3... By using this app as a reference actually we can try different cables and check to see if they works well or not, which is great.
[Android Software Development] zard:
Thanks for coming up with this great app. I was able to get 1800mA using my stock Note 2 LTE charger and a short usb cable from my Sony NFC speaker charger. I tried on my Nexus 7 3G but I believe this app won't work on that. I found this link http://xdaforums.com/showthread.php?p=39253120 on Nexus 7 with the path indicated. Can you look into supporting Nexus 7 & 7 3G please? I can help you to test, just PM me.
[Android Software Development] KryptosXLayer2:
I'd just like to say THANKS again for this app, I received (3) pairs of OEM Samsung 2.0A chargers and cables in the mail today from China, reputable seller on Amazon listed them as OEM, but when they arrived, the chargers output 2.0A but the cables limit it to 960mA max, some as low as 860mA. When using the cable that came with my S4 on these chargers, I see the full 1900mA, so the cables are obviously the problem.... without this app, I would have just accepted the fact that they were OEM and took it on faith that they were outputting 2.0A, not knowing that I just bought the same effective output as the plenty of 1.0A cables I already have!

SO...... Thanks again!
[Android Software Development] Parafly:
Thanks for this app. I'm on a verizon S4 and Max is always blank as well. I do see max as 1900 though in sys/class/power_supply/sec-charger/current_max

That said, I have wierd results with my OEM charger. I am only getting 460 reporteda s Current Now. That'sw ith the 2A charger. With an 850mA charger I have in the office it shows as 860mA current now. So I am getting twice the charging rate with a half the power app. WTF.
[Android Software Development] Damijan81:
Hi All

Just thought i would give my experiance.

Started off with a stock I9300 from Australia with 4.1.2 and had no problems with charging or the battery, I installed Delta Rom 4.2.2 exactly to the instructions and everything went fine. Almost straight away i had a Issue with the battery and charging times. I am at my desk most times and when my battery gets low i plug it into a wall charger and it fills it up quick enough that i dont even think about it. Once I updated to Delta 4.2.2 I plugged in the phone and it wouldn't charge past 49% and that took about 5 or 6 hours to get there. I installed Galaxy Charging Current app and that charger charges at around 440 to 450 on average. I tried different Charges and got different results including the speed it would charge and voltages. In the end i got sick of swapping charges around and re-flashed a fresh full wipe Delta 4.1.2 with Siyah Kernal option ticked, since then i have no problems with charging or battery issues everything is back to how it was. Also to note that the voltages from all the different charges are still the same and that original charger i used at my desk now works fine like it did before.

Leads me to think that it is a Rom issue not the cable as every time i flashed a 4.2.2 i had some issue or the other and when i went back to a 4.1.2 based rom all the Issues left.

Is it possible also that those that are on completely Stock and non rooted phones have automatic software enabled and an update has come in over night which then brings with it this issue on stock untouched phones. Just a thought?

This is very interesting, I have SGS 3 International i9300 and did some research. What I discovered is that the problem is with the stock cable (with 4 pins) not the stock USB charger (tested both Samsung stock USB charger and Apple USB charger). I have 2 other cables, - one LG and other generic one (both 5 pins) and they both produce 1000 whereas the stock cable only 800...

The strange thing is that 4-pin connectors are used also on stock wall chargers for SGS-2 and SGS-3 Mini... so the question is really WHY Samsung would use those supposedly inferior cables to ship with their devices? Obviously there's a reason, I just don't know what it is... some have said slower charging leads to longer batter life, cannot verify that yet, but I'd noticed this to be true about earlier phones I had, the ones that fully charged in 2 hours had lousy battery life...

Hey Op its works on the galaxy s4
[Android Software Development] flash608:
It`s as you wrote about the pins but you have to know that S4 stock cable got 4 pins as well as older brother but max current is 1900mA. So it looks like the fifth pin doesn`t make any difference.

Just one interesting observation. I`ve used my Nokia stock charger (700mA output), i have cutted the end of the cable near the plug. Then i`ve made a dual charger using microUSB plug and nokia bolt plug (that little circle charging plug), i crossed them togheter using only Power lines (data wires aren`t connected) and what`s interesting that on that charger using microUSB plug this app shows 1900mA when the charger can only output 700mA :)

In my fidings the 5 pin doesn`t make any difference but in case you are using car charger without data transfer you can cross two cable with gives you faster charging. Video on YT http://www.youtube.com/watch?v=9LZt4pW97P8 tested myself on older S2 and many different cables and it works.

---------- Post added at 09:25 AM ---------- Previous post was at 09:23 AM ----------

The charging current isn`t constant it changes during the charging. It`s normal.
[Android Software Development] GR0S:
Bought new cable for 10$. It charges 800 mA.

Stock cable charged 200 mA.

Now I want to return new cable to get GOOD cable which will charge without dirty hacks.

I believe there is reason for kernel dropping current, so those hacks will REDUCE charging voltage, decreasing capacity.

UPD: new cable charges 700 mA with 100 mA safety margin disabled. My charger and cable are faulty. Best way to fix charging problems is new charger. My friend had similar problem, he bought new note2 charger and used nokia N8 stock cable.

UPD2: current falls randomly, probably due to unstable charger voltage output. Will try apple's charger with new cable. My previous cable was faulty anyway, because it was working unstable even with PC.
[Android Software Development] RDI:
What you need is a 2100mA AC Charger that fast charges in the Samsung standard not Apple standard. The best charger, that does both Standards, is here: http://pages.ebay.com/link/?nav=item.view&id=251289572606

I use it and the author of this software uses one.
[Android Software Development] GR0S:
There is no two "standarts". There is USB specification. Power goes via wire 1 and wire 4. Nothing else.
[Android Software Development] RDI:
If that is true then why does a Samsung smartphone when plugged into a "Apple standard" 2100mA, AC charger say "Charging USB" instead of "Charging AC"?
[Android Software Development] GR0S:
Because Apple uses their own "standart". Apple never followed standarts
[Android Software Development] reS28raM:
So there are two standards.

It sounds like the results I get if I use a non-Samsung standard charger to charge my Note 2. Go into settings/battery and see if it says "Charging USB"

non-Samsung standard or "Charging AC" Samsung standard. If it comes up "Charging AC" then you have a weak charger. But I believe that you will find it says "Charging USB"

[Android Software Development] Formhault:
I don't think this app displays current input accurately.

I have a Note 2, a 2A charger, a good cable... a kernel + a customization app through which I can alter the input currents however I want.

Say I modify the DCP AC Input Current and DCP AC Charge Current to 2000mA. Then, this app will show "Max" : 2000. If I set it to 1925... it will show 1925...

When I modify that in the app, it just writes to a file the AC_MAX_INPUT value or something like that, which Galaxy Current app simply reads, I guess.

----

For the "Now" value... it will show whatever the maximum is, minus 1.

Battery Monitor Widget, on the other hand, shows more oscillating values (+817, +754 etc.) and I am inclined to believe THAT is showing accurate values.

My 3100mAh battery charged from a 2A charger in ~3 hours. That doesn't mean it charged at 2A per hour... but rather at +1.5A some times, +800mA some times (as shown in Battery Monitor Widget).

:eek: :confused:
[Android Software Development] reS28raM:
The app is quite precise, it takes values from the /sys filesystem which is updated by the kernel itself which uses the charger's driver which is quite a good one.

If you want see that yourself at the beginning of the thread (in the first posts) you can find the full path to the /sys/* files involved and check their values yourself.

The truth is... Most of usb cables around are defective, the problem seems to be in the microusb connector.

USB cable's manufacturer never imagined that one day it would be possible to use our Galaxy devices to precisely tests the quality of their products... ;)

THIS THREAD IS NOT ENOUGH VISIBLE!

25 pages? I opened a similar one on my forum and in a month we filled 20 pages solving tens of slow-charging problems on Galaxy S3. Someone here on xda can do anything about this?

I will donate today, thanks again to the developer for the brilliant idea! :)
