How does charging cable affects your charging? - Galaxy S III Q&A, Help & Troubleshooting

Hello I have a few questions in mind and hope that we can discuss this together.
How come some micro USB cable are unable to charge my phone? charging icon does not appear immediatly after plugged in, takes about a minute for the icon to appear and charging is none. Current widget does appear to display current going into my phone, but it is not charging at all
what factor plays a part in charging other than current + voltage?
does 4/5pin plays a part?
Thanks!

Bad cables can do this. You must try with a new branded one.

thank you for your reply. basically i bought a dozen of cables from some online stores. they are giving me the same current through currentwidget, but they are not charging at all. so it sort of confused me.

Are these cables that include the plug, or that have a male USB that plugs into a female on the wall adapter ? Have you tried a different wall adapter ? I find these vary loads, as to the cables. Some are for data sync, some are for charging and sync and some just for charging. All depends on the resistance presented to the phone and this then effects how much current it draws.
Have a google about - theres lots on this.

[Q] thunderbolt not charging well with other usb cables

i bought two extra usb cables from amazon, i can't link to them since i don't have enough posts yet, but they're the "EMPIRE USB Data Cable for Verizon HTC ThunderBolt" from amazon
i intentionally looked for some that said for use with thunderbolt in case there was something different than just a micro-usb cable; however, it does not seem that these cables charge as well as the cable that ships. it takes several hours even when trying to charge with the original AC adapter using one of these cables vs the ~1.5-2 hours with the cable that comes with. When trying to use a computer or a car adapter it just holds the charge steady, if using navigation it actually drops battery while plugged in!
is there something i'm missing here? they should all be the same right? can anyone point me to some that actually work? (preferably from amazon since i have gift cards there)
I've had the same problem.
Make sure you are getting the correct voltage. I think my issues are that USB is a slower charge than outlets and the "extra" charger I had was for my bluetooth which had a lower voltage.

yeah, i understand that usb from the computer will be a lower voltage, which is what i thought the issue was at first. but then i tried using the original AC adapter with the replacement usb cable and it was slower than the original cable. i don't see why the cable would make a difference, but it definitely appears to.
i downloaded the current widget and can see that just swapping between the OEM cable and the aftermarket cable the charging current is quite different. ~+600ma with the OEM and -100ma to +300ma with the aftermarket (yes at times it was LOSING charge while plugged in using the aftermarket)

You should never use any other cable than the one provided with your Thunderbolt. On the site it may say that it "Works" with the Thunderbolt but that doesn't mean you are going to get the performance you need out of it. I have had that problem plenty of times with older cables and sadly it keeps me buying the slightly overpriced cables from Verizon so I know that I get what I need.

It sounds like a defective cable. Check to see how it's charging (AC or USB). If it says USB when connected to the HTC charger, the cable is bad.
I use micro-USB cables I got from Monoprice, no problems.

It's not defective, it's just not designed for charging. OP, always make sure it says it is a charger cable, not a data cable, when you buy one.

BS. You have no clue what you're talking about. The TB follows the USB charging specification.
The thing about USB (Universal serial bus) cables is that they are UNIVERSAL. It doesn't matter where you get them from, what they say, or what they are branded. They have to meet certain specs (including materials and current capacity) in order to get the USB label.
If you're having a problem, I am 99% sure the cable is not the issue.
Try out monoprice.com. I've used them for years. You can get 3 wall chargers, 5 USB cables and 2 car chargers (all 1A) for like $25, shipped.

yeah, i'm with you, that's why i posed to see if there was something i'm missing and didn't know about. i'm a computer engineer so i know a cable is a cable is a cable, which is why i was like wtf when these didn't work the same.
thanks all, at least i know i didn't miss something and these should work the same.
ive had this problem on every phone. takes forever to charge through usb.
A USB cable is a USB cable is a USB cable is a USB cable.
If you are doing seat of your pants checks on charging, etc, they are never going to be accurate. CPU usage, network usage, etc while the phone is charging will affect how quickly it does charge. The stock charger provides 1000mA to charge the device, if you are using it, or another app is doing something (downloading data, using cpu, etc) it will not charge as quickly because power is being drained as it is being charged.
There is too much that would cause a slower charge state that you can't compensate for by a seat of the pants judgement on charging.
Its all about the mA.
No, thats not a storm. Its just my Thunderbolt layin down this post.
I have the same issue. I have tried four different usb cables with the oem charger and only two charge normally, the oem and one that I had with an old phone that I put a mini to micro adapter on to fit. The other two, one actually micro one mini to micro adapted, charge extremely slow. Yes a cable is a cable, but given I use the oem charger, the only differing things are the cables.
For what it's worth, I hate to burst your bubbles but not all USB cables are equal. And, in fact, not all phones are optimized for USB cables. Just because a cable looks like a USB cable and works as a USB cable doesn't mean that it is ONLY a USB cable. There are quite a few devices out there that can be charged (albeit slowly) with a USB cable but can be charged quickly with a cable that you only think is a USB cable. Take the Nook Color, for instance. The cable that it comes with looks like a USB cable on all accounts, but it's not. I forget which (both are techniques currently used) but either it has extra pins or has a data pin repurposed to provide additional power so it can charge faster. There are quite a few devices out there that are like this, and it seems like the number of these devices just keep growing and growing.
Now these "non-USB" devices still support USB standards, and can be charged via USB standard cables. However, they are optimized for non-USB standards and charge faster with these non-USB cables.
I'm honestly not sure if our Thunderbolts are such a device or not, and if the cables that they come with are such cables. They very well could be, and what the OP claims goes along with that theory. But honestly, I simply do not know.
EDIT:
Oh, and one more example. Go take a look at the custom "USB" cables that Team Blackhat had made that can power Motorola devices in CWM without a battery in the device. This is yet another example of where a USB cable isn't a USB cable.
Having the data pins connected to 5v sources is part of the charger itself; it has nothing to do with the cable.
Every USB cable has 4 pins: two 5v+, a gnd and a 5v- if the second + and - aren't connected to a source in the charger, you will only get a 0.5A charge, and it will go slow. If the charger DOES have them connected, you get the full 1A, and a much faster charge.
If the charger or cable is anything different then it is not USB. End of story. I know some phones have extra pins in the USB location for video out, for example, but those don't interfere with the standard USB pins.

Wrong, kinda. Check this out: http://en.wikipedia.org/wiki/Nook_Color#USB_port
The Nook Color uses a modified connector with two depths. The first depth is compatible with micro-usb (5-conductor), while the second depth has 12 conductors. This change was made to increase the amount of power available to charge the larger battery of the Nook Color when using the included cable.
Because of this, the USB cable included with the Nook Color is physically incompatible with other devices employing standard micro-usb connectors. However, the Nook Color itself is physically compatible with standard micro-usb cords.

Now I realize that calling this a "USB Cable" might be stretching the definition of "USB Cable" (hence the "wrong, kinda" comment) but more than likely, most people have no clue that one cable is different than another, so the end result is that, for all practical purposes, we DO have different types of USB cables.

Close, but not quite.
The pins are +5, Ground, +D and -D. All power is drawn through the +5 and Ground lines. The D lines are used for data transfer.
Per the USB specifications, a device can only draw 100 mA without enumerating (negotiating via USB, implies both ends have "intelligence"). If it can enumerate, it can negotiate for up to 500 mA (e.g. plugged into a PC which has a "driver" which recognizes the phone).
There are also specifications for DCPs (Dedicated Charging Ports). For these, the D+ and D- pins (the center two in a full sized USB connector) on the charger must be connected together with no more than 200 Ohms. These ports must provide at least 500 mA, but can provide more (micro-USB connectors are rated to 1.8 A). That's how the phone knows it can draw more than 100 mA from a "dumb" power adapter.
The TB follows the USB charging spec. Here are some things that can happen.
If it's plugged into a charger which doesn't follow the USB spec (D+ and D- not connected together, these are fairly common), it can only draw 100 mA. It doesn't matter if you bought a "2.5 Amp USB charger," if the charger doesn't follow the spec, a device which does isn't supposed to draw more than 100 mA. That's enough to charge it very slowly when the screen is off and it's idling. If the phone is doing anything, the battery will actually be discharging. This is a problem which seems to be common with many car chargers. A lot of device will ignore the 100 mA spec limit, and draw whatever they can, which is why they will charge from an improper adapter.
It's plugged into a PC with no driver - same thing.
It's plugged into a PC with a driver - it can negotiate and pull 500 mA. This is enough to charge while running in almost all cases (it might be on the edge if streaming video via 4G with GPS on, etc.) It will charge, but not as fast as it could.
For all of the above, a TB will show "USB" as the charging type.
It's plugged into a USB DCP. By spec, these must be able to deliver at least 500 mA. The AC adapter shipped with the TB is marked 1.0 A, and the phone won't draw more than 1.0 A (the most I've seen it use to charge the battery is ~800 mA). This will allows the fastest charging. With a DCP, the TB will show "AC" as the charging type.
Cables can have the same effect - all USB cables are supposed to be basically the same. But, some manufacturer's play loose with the spec. They may have "USB" cables with resistors or other changes inside which signal different things to a device. They may not have proper gauge wiring. It may just be a bad cable. Etc.
I've charged the TB with the stock AC charger using both the stock cable, and one I got from Monoprice. Works fine. I've also got a USB hub I converted to a charging station (follows the spec for USB dedicated charging ports), and that works fine with both the original and the Monoprice cables.
I have run into "flaky" cables, where they only work right if jiggled around a bit. Maybe they've been flexed too much, and have an intermittent connection. Maybe the contacts have gotten dirty. I don't worry about it, I just throw those away, you can get new ones from Monoprice for less than a buck.
Thanks Mike S (Also my initials, lol) That's what I get for posting after staying up a bit too late.
well i just ordered two micro usb cables from monoprice. we'll see if those fare any better.
the only thing i can guess is the power wires are a small gauge in the cables i bought from amazon. monoprice has two different kinds, some use 28awg for both data/power and then they have some that have 24awg for power and 28awg for data. i'm hoping that getting the bigger wire for the power will solve the issue.
also, i've been using juiceplotter and you can visibly see the slope of the charge change when switching just between these cables i bought vs the stock one when using the HTC charger so i'm pretty certain it's the cable.

Battery Monitor Widget will do that, and more, including telling you whether it's charging AC or USB.
You can also check the charging type from Home Settings/About Phone/Battery/Battery Status.

Fast charging - how to check?

Hi,
I've recently bought on eBay a bullet-style car charger that claims to give 1-2 amps to two USB ports. I've checked middle pins on both ports - shorted, so it must do a fast mode.
However, with my Note running navigation and media player, I saw it not charging but slowly draining! I used before the charger from my old Dell Streak - it worked fine.
Hard way to check is to solder a converter USB male to female, and measure the current.
Is there an easy way, like opening some engineering menu, and checking the mode (slow/fast) and the current?
This may help.

Thanks, that was very helpful! Saved me trouble with soldering iron.
Although it has a bug and shows amp value 10 times more (like 5000 mA instead of 500), it does the job for me.

Did you find a solution for monitoring fast charging?
Should I only monitor the Voltage and Amps? In case, how must they be??
Ps: so Fast Charging is a matter of having a charger with middle pins shorted??
Tnx.

Fast charge cable 1000mA+

so got tired of not finding a fast charge mod so I mod the cable.
took a realy thin cheap USB cable and cut it in two. on the phone side chortsircut the data cables (white and grean) then connected the vcc+ and ground- normal.
the only reason I cut it in two was to be able to tread a shrink tube on the cable.
now I get fast charge from car and power pack and. and it works perfect.
now stop saying u need a special or expensive cable.
u need a knife and shrink tube and a heat gun (a cigaret lighter works)
and no u can't use this cable for datacynk only charge

Cool, thanks man, I'm gonna do that.
Why blow data when you can just get a cheap 4$ cable from newegg with 22 awg power leads. I linked it in confirmed usb cable thread. You destroyed a cable and made it special, hence using a special one instead of standard. The base is pre shorted. You increased AWG technically. Get it? You made a charge only cable, when these are special and can be had cheap anywhere. Buy a nice 4$ standard one with the right power lead awg and you can use it for anything.
...or.. Crazy idea here. Get an Android charger?
Cutting up USB cables is a bad idea, especially shorting them out. The data pins are not supposed to be shorted, generally 200Ohms is expected.
They are suppose to be shorted with fast charge... the base normally does this on plug in on AC switch. A USB3 port also does this... all he did was make a charge only cable. With fast charge 2 though, you won't make it much past 1A this way, just like USB3. Why our stock cable has thick power lead AWG and the phone can reach 1.8A.

As I said, 200ohm, not shorted... Anyway.
unless the plugg that u connect the USB cable in i sent chortcircut it won't fast charge whatever cable u use. this is for making a charge cable to use with carcharger ore power packs. of u use a wallcharger it's 99% certain it is already chotend and u don't need this. but if u use the original cable (fastcharge) it won't fast charge in a power pack or car charger.
and I charge att same speed with this cable then original charger cable that came with the phone. measured 1.8a with this cable that's all my Powerpack can output. can probably go higher depending on how mutch the phone can use.
it's li-po so should be able to charge 0-100% in 20min but whill shorten battery life and don't think oer phones can handle it
I fast charge with 3 different cables. Again, it's the AWG. Facts don't lie. My power pack and car charger are pre shorted, so all good. If not pre shorted though, you are correct sir.
my wasn't that's why I made this. so no matter what cable used it won't fast charge. Som people also say u have to by a expensive cable with is bull####
if someone can provide a link with a preshortens cable... well then show it. unable to find any
It is legit. I did this with a car USB cable when I had my One X. It would only charge at USB rate (500ma) even though it was a 1A charger. Using navigation the battery would discharge faster than it charged. Tried various cables, and only got it to work by shorting the data pair. After that it charged AC at full 1A.

Several available on Amazon:

Not always. My car cigarette adapter is modded to short data pins. It fast charges all my other devices and even my tablets, but doesn't even charge my G2. It says its charging, no slow charging messages, but still depletes battery. Only way toncharge in my car is to use the second USB port that is unmodded, which slow charges. Annoying.
I still think there is a software bug limiting the charging speeds because you can get different speeds by plugging in the same cable mulitple times.

We aren't saying you are wrong, you are just doing something different. It's not about expensive, its about thickness for the combo usb cable. Just the awg. What your solution does is increase awg. They are called charge only cables (pre-post short). What people were searching for are COMBO cables. You are using/doing something different. Why titles are called "working USB" cables, not charge only. We already knew this. There is bugs. That was apparent in the voltage testing. Something in the kernel isn't playing right at all times. I have seen this on my car charger. With no change in conditions, I can sometimes charge 200mA's higher with a replug.

The included home charger for the G2 is rated at 1.8A -- use anything smaller, and you'll see the pop up warning on the phone that charging will be slow and that you should use the "official" charger.
My guess -- if you can find a car charger that actually will put out as much as the phone wants to draw (e.g., 1.8A), and THEN use your shorted data lines, you'll see fast charging of the G2 in your car.

The 3SIXT micro USB charger I have is rated to 1A not modded, just bog standard. When charging I checked the battery stats and it says AC charging. Now I don't know if it has the data pins pre-shorted, but it managed to boost my battery by 10% in under 20 minutes. The phone was idle, but that's not bad going for a 1A $10 charger.

not true have tried 3 other chargers 1.2 1.0 and 0.8 all say fastcharge (ac) with my modes cable. as long as it's over 500ma and with a cable with data pins shortend the slow charge warning is removed an the phone thinks it's charging from ac
charging my phone now with a Powerpack with 1a output and it says fastcharge (ac)
if I use the original cable it goes to slowcharging 500ma iv meshurd befor I put on the shrinking tube for isolation
and a car charger can output in theory 5-20a depending on your fuse in the car
the charging current is controlled by kernels in so phone. my old sensation u culd mod with a fastcharge Kernel so it never limited to 500ma always use max.
Samsung even has the ability to do a full charge in 30min but disabled in Kernel.
lg - g2 uses lipo battery's and culd actually be charged in less then 20min but if we do that u have to replace the battery every 6month at the best.
and lipo are extremely sensitive to over charge and the cells have to be charged with precision balans not to explode or swell.

[Q] Increase charge rate when using MHL

Hello everyone,
I was wondering if there is a way to increase the charge rate while connected to an MHL adapter.
I have a 2014 Civic Si that literally has an HDMI input for the head unit.
I bought an MHL adapter and it works very well other than a safety limitation that stops screen mirroring while driving, and the fact that even if I am just using it to get the best quality audio into my head unit with the screen turned off, the MHL adapter uses more current than it returns to the phone, resulting in battery loss.
I have the usb power connected to a 2 amp 12v charger that works fantastic when it is just connected with a regular micro usb cable so I know its not the charger.
I have found some evidence that there is a mod that can basically tell the phone that it is connected via AC to take more current.
Would be awesome if someone could provide this, or another solution to this problem. I imagine there are a lot of people like me out there who like to use MHL adapters but don't want their battery to die.
Thanks
Check the quality of the cord. If it's some cheapo one from like eBay or something that may be the problem.
I've found that some of my older degraded cords won't charge the phone while I'm using it.
Also if you roll/folded the cord up sometimes it can pinch it just right to not supply the right charging power.

To be clear it does show that it is charging (via USB) but its using more current than its getting thus end result is the drain.
It could very well be the cable - hence why I am asking if anyone can recommend a tried and tested solution of MHL + charge that actually charges it quickly.
Thanks,

Magnetic wired charging

For over 2 years I have been using a charging lead with a magnetic connection and a USB adaptor to my M31 with no trouble. It is particularly useful in the car where I can easily attach (and detach) the charging lead with one hand. Now, for over a week, it is hardly charging at all, with just a pathetic 75 - 125 milliamps. This compares to 2000+ mA on a regular plug-in charger.
I have tried several different magnetic connectors and adaptors, and they are all the same. It seems that something may have changed with the software on the phone, but I would be grateful if anyone has any ideas on restoring the charging functionality.

Have you tried changing the cable for the previously used magnetic link?
Do these other magnetic adapters charge other devices correctly?
The contacts of the adapters or in the cable may have worn out. A poor connection on the contacts results in less current flow.
Yes, I have tried different USB-C adaptors and cables but the charging rate is still extremely poor on the magnetic cable compared to the USB-C cable. I have attached two screen shots to compare the two readings.

Just downgrade your firmware to older version using Odin. Download from samfw.com
