[Q] Charging Current on different cables? - Galaxy S III Q&A, Help & Troubleshooting

okay... i have the i9300 model.. and i've been charging my phone overnight using the stock cable and charger... recent days i noticed that my phone is taking 6 hrs to 8 hrs to charge a full hundred percent... so i coupled my charger with another good microusb cable and tried charging... and it got charged in 2hrs to a full... i tried different electricity ports in the house and still the same... to check the current.. i downloaded "galaxy charging current" from the playstore to check current drawn during charging and on the stock cable it shows 300 while with another usb cable it shows 1000... besides the stock samsung cable has 4 pins in the micro end,, while the normal one has 5 pins... why is it getting charged at 300? and why at 1000 on a normal cable?

what do you mean?

Multiple posts on the subject of usb charging better with some cables . jje

Short story: YES
I have a cheap no-name 1-m extension cable that makes my phone charge at ~500 mA with the original charger, according to Battery Monitor Widget (https://play.google.com/store/apps/details?id=ccc71.bmw). I later bought a longer (2 m) extension from "Cables to Go" (Amazon), same length, and I get up to ~1500 mA. So there's your answer. I haven't tested it with a DMM to tell whether it's the data or power wires, though.

Yes, the calbe do matters. I suggest you to purchase Micro USB calbes from trusted mobile accessories shop. Last month,I purchased (flat type) micro usb cable from a computer shop, no matter if I put to charge for the whole day, it heats up my phone but doesn't charge even 1%. Buying the wrong and low quality cable can cause damage to your phone and battery.

Faster Charging 2amp Touchpad Charger for $4.99

I noticed a lot of people want a fast charger for the Note. This charger is for the Touchpad. I have this and it works really well. It charges faster than the OEM charger that came with the Note.
Not to mention, it is on sale right now for less than $5. Go grab one. From past experience, I used this at 15% battery life and charged for an hour and I was back over to 80%.:victory:

Is the usb cable that comes with it the same as the note takes?they don't show a pic of the other end and is it a charge only cable?If yes and yes I'm a gonna get one.Thanks

Yes, it is a micro USB cable. One end is USB and other is micro USB. The cable length is longer than most phone cables. I haven't measured it, but from my plug to my desk, I still have excess cable compared to the original one from the phone.
Thank you, getting one!
This have been discussed hundreds time before....
That 1amp is the output of the charger which forwards the current to kernel of the device... NOTE can only intake 1 amp current... ( remove your battery and read the dam sticker :thumbup
Even though you will supply 2 3 4 5 amp... The maximum in would be 1 amp ONLY...
SECONDLY, micro usb cables have a restriction of carrying current... They cannot pass more than 1 amp current successfully... Therefore galaxy tab series does not come with micro usb slots....
Lastly my recommendation would be NOT to waste money on any other chargers...

It has been discussed, but it DOES charge faster than a conventional 1amp charger. If you don't have the charger and have nothing to compare with, then I don't think you can say it does not work.
Go check FCC about the charge. Also, the cables provided DOES carry a 2amp charge. Our note can handle fast charging but throttles down to a slower charging rate after 80%.
having a micro usb slot or not have a micro usb slot has nothing to do with the current it can handle.
Ipads and Iphones have the same connector but yet one has a 1amp charger and the other a 2amp charger.

You don't have to get your panties in a twist. Rather than just read forums and assume the worst of everything try it for yourself. I've tried both and it is faster. Just trying to help my fellow Note users to get the best out of their phones.
btw, what are you screaming about pull out the battery and read? you tell me what you want us to know. RATED: 3.7V; 1500mA... WOW ok that proves your point...sigh:silly:

As an HP TouchPad owner, I can confirm that the cable provided with the charger are 'special'. My TP will not charge with any other MicroUSB cable connected to the official charger, the same cables which won't charge the TP will charge the Note. (I also own the HP touchstone dock, which the TP spends most of it's life sitting on.)

I have four different wall chargers, including two of this HP barrel adapter (one that came with the TouchPad, one that came with the Touchstone). With the supplied cable, it does charge the TouchPad very quickly. From webOS, the net charge rate is about 1.6 A with the screen on, so probably close to 2 A coming out the USB port.
However, when you plug a Note into this charger, the Note will still only draw 1 A. I have other AC chargers that are also able to supply 1 A to the Note, so in that respect this HP charger isn't anything special. However, it is only $5, which is a good deal.

I've found that the microUSB cable that comes with the Note, when paired with the HP TouchPad's AC charger, will supply 2 A. At least, that's what the OS reports: /sys/devices/platform/usb_gadget/current-mA shows "2000". Plugging the TouchPad into the Note's AC charger shows a value of "900". Plugging it into my laptop's USB port drops that value down to "500", as expected.
I bought two a week ago off Amazon for $10 each. $5 each with free shipping is a steal. I picked up three more. Thanks for posting this deal. I get 1A charging with either the stock charger or TP charger. I like to have a few extra chargers to sprinkle around at home or work (for my Note and the other devices I own that charge off USB.... including a TP).

When you charge your phone using this HP microUSB cable, do you have issue with NO DEEP SLEEP when unplugging the Note from the charger?
There has been issues reported in XDA where, depending on the USB cables used to charge the Note (connected to computer OR power charger), if you unplug the Note, it will not go DEEP SLEEP, causing significant power drain.
This does NOT happen when the Note is charged using the cable that came with the Note.
Download Current Widget from the play store. Add widget to home screen and you will realize that your phone is not charging any more than 1 amp as designed.
Try the usb out from your pc and you will see about half an amp.

I have the galaxy tab brick charger the HP touch pad charger and my note charging brick....the touchpad charger works faster...but I feel like it doesn't get fully charged..seems to die faster?. I used the galaxy tab brick...slow to charge warms my phone up nicely...I'd stick with the original note charger.

I charge my Note overnight using my Touchpad's MicroUSB cable plugged into the Samsung charger, and I don't experience any difference in power drain.
Where is that post from the guy who put all these petty arguments to rest with scientific tests of all the various options and results??
Good lord people it's a charger for a phone .. no need to get so heated!
(unlike my stock charger.. which gets very heated!)
great price!!!
ordered 3 of them
the price is way cheaper than just a single micro usb cable shipped from other stores
i have 3 already
1 at work, 2 for home.
definitely faster than OEM. I charge overnight, no issues. had for around 5-6 months now. and i can use the phone while charging.
fact is that it DOES charge faster.
i recommend it
WOW***
Great price I bought 2!

Charging problems, SGS3 micro usb cable different pinout?

Hi everybody!
I'm having some problems when charging my device. I've noticed that when I use the stock charger with the stock micro USB data cable, the phone stops charging and it just charges the battery in 1% to 5% after I plugged it on the wall, and the charging led remains on. So I've left the phone plugged into the charger for 2 hours and nothing happens, the device remains cool and the charger remains cool either.
I tested the following scenaries and the results are pretty weird:
a) I tried using the stock SGS3's charger with my Nokia CA-101 data cable, and the phone charges successfully in about 2.5 hours from 0-100%.
b) I used the stock SGS3's charger and the stock data cable, and charged my old Xperia X10 mini pro and successfully charged 0-100% in about 1 hour.
c) I tried charging my SGS3 with it's stock data cable from USB port and It seems to charge very slowly: 20% per hour.
I don't like using different accesories to charge my phone, because I read somewhere that Samsung uses diferent usb pin arrangement because of the Device ID pin.
So my questions are:
What is happening with the phone/battery/charger/usb cable? They seem working well separately but not together.
Does the samsung micro usb data cable uses different pin arrangement than standad micro usb data cable? or Can I keep using my Nokia CA-101 micro usb data cable?
Any ideas?
Thanks in advance.

Hi.
I have the Samsung Galaxy S3 it is a remarkably simple phone to disassemble and I'm thankful for that since...
I also had 6 different chargers and cables that would not charge the phone reliably, I took it to Sprint and of course they plugged it in and it charged ok when left alone not moved in any way. Well the charging for me was very intermittent and some cables not at all. It was as if the plug was inserted and removed and inserted over and over again, typical problem if the solder of some connection on the PCB is broken or high resistance for some reason.
I removed the PCB from the phone and examined it to find a micro USB mounted to the PCB with 6 + 5 additional conductors, the 6 that were in the middle of the connector I believe connect directly to the conductors of the USB cable. The other 5, 2 on one side and 3 on the other of the main 6 were broken solder joints on 2 of them. I have a really fine tip solder iron and a microscope which helps but is not totally necessary to re-wet the solder on each pin of the connector. Now my phone works like brand new!!!
I have at least 33 years experience with soldering, so this operation may not be for everyone.
Good luck,
Dude I wish I had the confidence to attempt something like that, well done you

Have you ever done simple mathematic & calcs based on the current output?
You have 2100mAh battery in SGS3, right? And you have STOCK charger. Output = 1A=1000mA => full charge (assuming 100% charging efficacy) would be 2.1hrs. Therefore, 2.5 hrs result from not 100% charging efficacy - simple.
Now, you have USB port in your laptop/computer. From USB 2.0 spec, its output is rated at 500mA => full charge would be more than 4hours.
The difference is result of not 100% efficacy of charging, but this, I assume, you can calculate by yourself (to give you a direction: how much data is spent from a phone to power the screen and to supplot media connection with computer, while charging via USB?)
Sorry that I had to give you some basic calcs from primary school, but... this is what you asked for.

[Q] Charge cable

Hey guys. I have many micro USB cables and 1 of them charges S3 like the original samsung cable, but the others don't charge fast enough or dont charge at all via USB.
I would like to buy other cables able to charge like the original. Is there any kind of cable specification that I should look? Can't find any info about this.
Or any cable recomendation that ships to brazil (deal extreme for example)?
Thank you!
I'm wondering the same thing; ordered 2 different micro usb cables off ebay (pretty cheap ones). One actually doesn't charge the phone at all - while connected, the phone actually discharged by 1% after 10mins. The other took 1 hour to charge 5%.
This is while connected to the original Samsung wall charger.

Aftermarket chargers question

Since I got my note 3 I've been charging it with my old AC chargers I bought on ebay which is a generic micro-usb charger (I got a couple of them laying around the appartment). I use my old chargers often because the samsung USB cable which was provided with the phone is always pluged into my desktop computer, and I didn't want to go trough the hassle of moving the cable all around the house to charge my phone.
Well anyway, so far I've notice charging times were pretty long(6-8hours), but I shrugged it off because I simply thought a bigger battery require longer to charge. But this weekend I slept off at my in-laws and I brought my samsung cable and AC adapter. I looked up with better battery stats and notice the charge time was around 3times as fast. (2hours or so for a 100% charge). Dammmn!
So why am I getting long charges with my ebay chargers?
Is it because they are cheap china product?
Is it because they don't have the USB3.0 port?
I'm thinking the USB3.0 has nothing to do with charging times if it's pluged with an AC adapter right? So my long charge time must be because of cheap products? Ok then, but if I want to buy additional chargers, or even a cradle for my bedside table. How can I know if they will have the best charge time? Am I forced to buy samsung branded stuff just to make sure?
Cause I'd be interested in something like this :

but I'm not gonna buy it if it takes double/triple charging time..

The Note 3 should charge in just over two hours with either USB 2 or 3 cables. If you download https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free&hl=en that will tell you the charging current. It should be 1200mA with the screen on and 1800mA with it off (trick is turn the screen off for 10s then back on and refresh and you should see 1800mA).
As long as the charger can deliver 1800mA and you are using a decent quality cable that should be all you need. Plugged into a USB port you'll only see 450mA on either USB 2 or 3.
Usually the ones that charge this quickly have an output of 2 amps. That is the output of the charger that came with the phone.

[Q] Samsung Galaxy S3 - charging too long with original cable

The thing is.. When I use original charger and original cable I had with phone in the box, it charges so slowly it can actually discharge while for example using skype.
Also funny thing is in settings/more/battery (android 4.3) it shows Charging (USB) when I am connected to the wall socket. The app "Galaxy charging current *lite*" shows it is receiving 460mA right now at average. It takes like whole night to charge. (at the time of posting it was 460mA, but I have to notice ,that using this original cable and charger from wall socket, phone itself somehow changes how much mA it takes as it varies from 100 up to 500 from long time observation)
When I use small micro usb – usb cable from my old Nokia 5800 Xpress music, it is charging at 1000mA and can charge even when using skype or anything else. With this cable I can charge from 0% to 100% in about 1-or 1,5h. (Here it is always constant - 1000 mA on average using that app)
I was googling and reading some posts from people with some S3 charging problems, and found that cables are the reason. I have noticed by visual comparison of S3 original cable and nokia cable that on the micro usb side, S3 cable has visible only 4 pins but nokia has visibl 5 pins.
1. Is the pin amount on usb micro side the reason for slower charging rate ?
2. But why the hell my phone thinks I am charging from USB when it is connected to wall socket when using original cable and charger ?
3. Is it safe to use that nokia cable to charge my phone ?
Thank you for replies !
Throw away the faulty charger, rating of the replacement is irrelevant as the phone controls the current used.

Hi, thank you for your reply. I apologize, may be because english is not my mother tongue, I do not undesrtand clearly what you are saying. Especially this part "rating of the replacement is irrelevant as "
May be I described my problem not accurately. I attached the photo of things I am writing about. I use still the same charger (number 1) I just either use original samsung cable I had with my S3 (number 2) or original nokia 5530 micro usb cable (number 3)
With S3 cable and original charger (1 + 2) it charges slowly and app in phone shows it gets at maximum 500 mA. Full charging (from 0% to 100%) takes about 8 hours at least. Also, sometimes the phone shows its connected to USB, although I am connected to wall socket. The thing is, that even when it shows AC, the app in the phone still shows it is getting somewhere between 100-500 mA. So charging is still slow. I have also noted, that current changes during the cycle of charging. Or even when I unplug and plug the charger, it sometimes changes the current (mA shown in the app)
When I use Nokia cable (1+3), current is always 1000 mA. Charging time is something more than hour (from 0% to 100%). Using the same charger, just changing the cable.
So I am unsure if it is safe to use that nokia cable. Can it somehow damage my battery or phone ?
Is the behavior of the original charger and cable (1+2) ok ?
Throw part 2 away.
Part 3 will not damage your phone.
