Hello all,
I recently purchased a gigabyte motherboard (z97x-gaming5) and it is supposed to have fast charging when your phone is connected to the usb ports. Gigabyte advertises 3x power for its usb. Well the most I've been able to get with my S5 is 450ma on usb 2 or 900ma on usb3 (using the galaxy charging current lite app). Definitely not the 3x usb that the board supposedly can put out. I think there may be a problem with the board detecting my phone because it says no phone connected and that the hardware doesn't support USB fast charging. Anyone have this problem before? I know I can just use the wall charger but that defeats the point of charging and copying files/backing up at the same time. I've included a picture of the on/off charger program and the message it tells me. Oh by the way, I'm using the Samsung USB driver v1.5.42.0. Thanks for any help.
Seemingly there's no support for the "official" 1,5A mode, only the special 2A mode, which is Apple iPad compatible, methinks.
And 900mA, always wanted to test that with my Note 10.1 2014, which I have much longer than the S5, but never found the time.

So it sounds like its only apple compatible? Bummer
If there's an Apple tool or a compatibility setting for the port(s) it may work at 1,4 or 1,5A, as Apple too has such a mode.

why? why did motorola use a proprietary charging cable? it would of been so nice to have a micro usb cable to charge the xoom. im very worried one day that needle proprietary cable going to break and it wont charge my xoom anymore.
it seems like motorola is a HUGE fan or proprietary cables, especially the v60 series flip phones.

Simple, many recent tablets use proprietary cables to allow higher current and faster charge times.
The average usb cable hooked up to your pc provides about 500mA
The proprietary cable for a modern tablet like the XOOM can deliver around
1.5A
With a micro USB cable it would take forever to charge the XOOM. Then people would be complaining about why the XOOM takes so incredibly long to charge, and bashing motorola for the problem. Instead Motorola chose to do it the intelligent way, by separating the charge function to a proprietary cable to allow very fast charging, and including the usb cable for data transfer.
When I see a proprietary cable I don't think - crap why do they do it this way. Instead I think wow great, that means this thing was designed for fast charges.

THANK YOU lol finally someone that understands.....
plus, the input voltage in to the tab is 12v, hard to get 12v from a 5v USB supply...
For a bit more info, I too wondered about USB charging. The limit seems to be when the Xoom is running, the current drain can be upwards of 400 mA so I could see a situation where a USB charger at 500 mA would overload if you did too much on the Xoom during charging. That would be good enough reason to avoid that design mess. "Do not use during charging" would not be sufficent protection. The Moto Mains Charger manages 1500 mA for a couple of hours which is wonderful. Now if only I could charge my Nexus S that quickly

right? about time
I am really glad that trickle charging is not possible with the Xoom, saves a lot of problems...I just wish they had used a different connector for the power. Something a bit more durable and commonly included in third party multichargers would have been nice...but one can't have everything.
I still support the seperate power cable choice for all kinds of reasons.

Just amazes me that folks will complain about anything and everything. Good grief, it charges in no time and runs more than a day when it does. What more can you expect?
I like the idea of a separate charger, but the only thing I take issue with is the design of the charger it self. Luckily, I just set mine on the dock before bed. The dock doesn't use that flimsy pin, it uses the two gold plates at the bottom to charge.

going to have to look into that dock cause i'm not to fond of the charger that it has. so the avg. use time is about a day, are you guys mod or heavy users(as you can tell i dont have mine yet ordered and waiting for it to show up)trying to get as much real world use info as i can
i love the proprietary cable. It is SOOO much faster. My Galaxy tab with a 4000 mAH battery took almost 4 hours to charge and i was lucky to get two days usage out of it (standby time and normal usage combined). My Xoom (no idea on mAH size) charges in 2 hours and i get 90 hours usage out of it (mainly standby but still a lot of screen on time, wiht a much larger and brighter screen to power). LOVE it.
Yeah I wouldn't worry about the Cable its seems durable, only thing I AM worried about was how you plug the wires all on the side of the device, I feel like there's abit of give on the wires when holding it sideways, I wish it was more like the iPad.
You know the first time I saw that the tablets used a seperate charging cable I was like, "why?" but then I stopped and think, there's no why a USB (let alone a micro-USB) can charge those suckers, so I'm personally glade that tablet makers did what they did and make it seperate.
I just wish they chose a 30-pin connector instead of this tiny one. The slightest mistake while it's charging (like say you trip over the cord), and there goes your xoom for repair/replacement.
Lets not rule out USB charging. Yes, I love going from 5% to 100% in about an hour. But I also have USB plugged in for hours on end when doing my thang. . That being said, we do not know for certain that USB charge is a hardware limitation. Yes, USB puts out 500mV. But I can tell the kernel to suck in whatever. If the hardware is capable, its doable.
I still think the option should have been given to us. Cuz many if not all of us have micro USB around. I for one only take a single micro USB in my pocket for my phone. So its would have Been nice to be able to charge both device with one charger. But I mean scull charge usually carry me all day. So I don't see it as a major problem right now.

Its actually 500mA not 500mV. Usb provides 5 volts at 500ma for usb 2.0 and that will be picked up to 900ma in usb 3.0. Even with this in mind it isn't the biggest problem with stoppinh usb charging in the xoom. The issue I believe is in the fact that the current charger is 12 volts and 1.5 amps. That's more than twice the volts at tripl the amperes.
Even beyond the amperage issue charging a battery that is set up to input from a 12 volt source with a 5 volts supply, even if it was possible with existing xoom hardware it would take forever!
I wish there was a way to have both options available for charging. Use the USB if you have no access to a AC adapter, albeit, a slower charge.
It seems that there's a false dichotomy here; the options aren't only trickle charge by usb and wall adapter with the proprietary connection. What about a wall charge via the usb port? I don't see why the usb port couldn't be used for the charge. I can trickle charge my n1 or I can plug it into an outlet, which charges the phone much faster. I'm sure the xoom could have been designed to suck in more power when conected to an outlet.
The only plus with the proprietary port is that we can charge and have the xoom connected to a computer or peripheral at the same time.
So, I have a macbook air with 2 usb 3.0 ports. But, when I plug in my normal 3.0 cable that I got with the note 3.. it most certainly does not charge as fast as it should.
It's charging very slow.. am I doing something wrong here? Anyone else?
I see that it says use as a media device (3.0 device) but it's greyed out and won't let me select it.

Hey. I have the exact same problem as you do. I just got my note 3 and plugged it into my 2013 macbook air. It wouldnt chsrge at all even though it says charging. So I just plugged it to thr wall and it took just a little over an hour to charge from 25 to 51%. Is this normal?
Sounds like it has something to do with the Darwin Kernel guys. Apple will probably have to do a patch to fix it.

Hm, well I noticed that if you go to Battery under Settings, it shows as Charging (USB) when plugged to the macbook. However, if you plug it using the wall outlet, it shows as Charging (AC).
Its either in the Kernel of the Macbook, or the Kernel of the GN3. If its the Macbook, well it will probably never happen. If its the GN3 kernel, you just have to be paitient and wait for custom recoveries so we can flash kernels and roms that support FastCharge on USB. USB 3.0 can supply the juice, it just has to be told to.

Okay that makes sense. Thanks for the quick answer. Btw, does the battery life improve as time goes by? My Note 3 dropped from 90 to 60% overnight.

Think in milliamps yall... Your wall charger that came with the note is 2000mA... The usb3 port on your mac is 900mA... that won't even charge when the screen is on... just enough to keep it from draining... it will charge very slowly (less than half speed) if you power down the Note3.

That's correct, but newer Macbook Pro's have a neat feature. They can provide up to 1600 mA additional current (apple devices e.g. iPad), wich adds up to 2.1A. If there was just a way to disguise a Note as an iPad.

Yeah, but knowing apple its only for apple devices. Pretty sure it drops well below that for non-apple devices.
Im not sure if anyone would be familiar with this, but on my samsung galaxy nexus there was an option that was universal on all kernels called "USB fast charge"
which basically all it did was cancel out the support of file transfer while connected through USB, but in return gave much higher charging speeds through USB. With it enabled my galaxy nexus would charge almost 4x faster.
Is there an option for this on the note 3? I have not rooted yet, but will in the next few days. I understand its up to the kernel dev's and whatnot to implement it in, but is this feature available on the note 3?

Bootloader Locked, can't flash Kernels, but the Note3 charges pretty damn fast using the Stock Cable plugged into an A/C outlet.
Total Segue here, but as a Brother to two gay siblings and an Uncle to a gay nephew, can we refrain from using the therm "that's so gay" when it comes to something derogatory?

with the wall charger the note 3 came with, reallly fast. Just as fast as you stated. But through USB, slow as molasses, probably 1% every 5 minutes. which is why i was wondering if the USB fast charge option was available. On my galaxy nexus charging through USB, it was just as slow. With USB fast charge turned on, it charged as fast as a wall charger through USB.

Hmmmmm, odd. Does your machine have USB3 ports? I know that's supposed to be good for only speedy file transfers, but I wonder if it also speeds up Charging? I've just never noticed slow trickle charging from my computer. The only time it's slow is when I use a regular USB2 cable in the car....then it's slower than molasses in January.

I do have USB3 available on my computer, but havnt tried it for charging yet. So far my USB charging has been done through my car which is some random usb 2 cable. Which now that i think about it i believe its only a 1 amp charger in my car, if that. It was enough for my galaxy nexus but probably not so for the note 3. The note 3 wall charger is i believe 2.0 amps?
Im wondering if charge rates matter through usb2 / 3.
If i get a 2.0 amp car charger and use it with a usb 2 cable, will i still achieve 2 amp charging speed? Or for the note 3, i have to use a usb 3 cable?

Not sure. My Laptop has a USB port that charges devices even when the Laptop is turned off, but I do know that my Nexus required less juice to charge up, where the N3 doesn't keep up when I charge it in the car, so I think it's the 1 / 2amp question
Bought it used off eBay so not sure if I have OEM parts, but I went from 37% battery to 70% in 4 hours. Slowest charging phone I've ever used.
I did a Google search and found this is a common problem and you need the correct charger and cable. My problem is I can't find any recent information on this and with the stuff I read, there was never a clear answer given.
Has this issue ever been figured out and if so, what charger and cable do I need to get?
The original charger is rated at 1.8A so look for that.
Check your lock screen if it says slow charging.
Ok so I used my moto x USB cable and the g2 turned into the fastest charging phone I've ever had. I didn't know a cable could make a difference. Same wall charger.
So is there a certain type of cable that I need?
It's just the way the pinout is on the cable I believe, if the phone sees it as a standard USB cable such as those used to connect it to a PC, it will go into slow charging mode as to not overdraw the USB port on the computer. The stock charger, and from some other phones, allow the charging at the full ~2A rate.
It isn't a 'problem' at all with the phone. As with any device, technically you should always use the accessories made specifically for it to get the best functionality. Or, at least buy a 3rd party item that is made to the same spec.

As you've discovered, the G2 (and many other USB devices) can request far more than the 500ma provided by traditional computer USB ports. For non-Apple devices (they broke the spec -- thanks Steve!), shorting the D+/D- pins will indicate to the device that it's plugged into a high power port, allowing it to request far more amperage.
There are specific "USB charging cables" that short these pins for you, if you don't feel like rolling your own. I bought this one:

It's your cable. Almost guarantee it. All cables are not created equally.
Is it both the charger brick and the USB cable that support fast charge or just the brick?
I ask because I want to use the longer USB cable from my Samsung Galaxy Tab S but somebody recently told me the cable also has to support fast charge. When connected, the phone says it is fast charging.
Can anybody confirm this?
Thank you.
Sent from my SM-G935F using Tapatalk
I used my longer cable I got with my galaxy tab s, and it fast charged fine.
Technically the brick, the cable and where you're plugging it into all play a part. But it's actually only the brick that's fast charge certified.
Granted if you buy a cheap cable, then it might not work. I have several cables that are very thin, and didn't work with fast charging. But they were cheap.
I have numerous white Samsung cables I've used over the years, going back to the one I got with my galaxy S3, and all of them work with fast charging.
If it's a decent cable and not cheap, chances are it'll be fine.
If it says its fast charging, then it is

I use plug that came with my note 4 and wire that come with one of my many xperia device so don't think the wire makes difference
Well last night I used my longer Tab S cable with the Fast Charge brick and it still charged ectremely fast, so that answers that question.
Thanks people.

Ye thats the first thing I checked, but a few days ago someone on these forums suggested that even tho it says Fast charging, it does not fast charge with a "non-fast charging" cable. I guess he was making it up.
