Hi guys,
as i'm working in a big soc company, I have access to some protocol analyser, and we connected the note 3 I just bought. I have a 9005 version, the euro snapdragon version.
It appears that driver doesn't declare itself as a USB3 but USB2 device, even if connected to a USB3 hub, and so there will be no possibility to access USB3 features:
-charge up to 900mah when connected to PC
-throughput up to 5gbps.
We will barely reach USB2 standards...
I verified on samsung website, and they advertise a USB3 micro connector, which is right... .
Hope that software release may change something to this... I check qualcomm webpage, and USB3 may be possible (if phone vendor ask for the feature, I suppose.).
Edit: I just found that MTP usb3 was not activated. When set to this (MPT usb3), it declares itself like a usb3 but charge at 384mah. I didn't check transfer speed...
My fault on this, but I would hope that USb connection delcares itself as a USB3 if the transciever is an USB3 one... this sucks because if you want it to charge correctly on PC, you need to change the USB type each time you connect it...
Thank you for the info

I don't think USB3 matters much on a phone. We are not talking SSD-like speeds, so even with 5gbps transfer rate on USB3 standard, you won't get anywhere close to that speed since you are writing to a (relatively) slow flash.
Digi+
If you have asus motherboard like (R4E) you can enable digi+ and it will super charge without even selecting the usb 3 but you will not be able to use MTP until you turn off digi+
I think someone can code a program (root required ?) which auto-selects the usb 3 option ounce its available.
A phone isnt meant to be charged on a PC anyways, first, a PC never gives the power the stock charger directly in outlet gives, if i remember, the USB post gives and output of half an amp, as the stock charger gives out 2 amps, the USB 3 is mostly for transfer speeds, which are much better with the note 3, i did a test because i still have my S4, transferring a 5GB file on from S4 to PC took 8 minutes with my S4, and 5 with my Note. So yes, it is USB 3. I mean, how else can you charge a 3200mah batteru from 0 to 100 in 1h?????????????
Here's what AnandTech said originally and their subsequent update.
The Galaxy Note 3 ships with USB 3.0, unfortunately at least in its current state it doesn't seem to get any benefit from the interface. Although the internal eMMC is capable of being read from at ~100MB/s, sustained transfers from the device over adb averaged around 30MB/s regardless of whether or not I connected the Note 3 to a USB 2.0 or 3.0 host.
Update: USB 3.0 does work on the Note 3, but only when connected to a Windows PC with USB 3.0. Doing so brings up a new option in the "USB Computer Connection" picker with USB 3.0 as an option. Ticking this alerts you that using USB 3.0 might interfere with calls and data, but then switches over. Connection transfer speed is indeed faster in this mode as well, like you'd expect.
That's strange. I used my USB 3.0 hub and USB 3.0 Connector directly to my phone
I was able to transfer files much faster than my other USB 2.0 devices
250 MB files are no problem the load bar just zips by and blam all done
A Blue Ray film of 8GB took about 3-4 minutes for me.

The device surely does receive USB 3 transfer speeds when being written directly to the internal storage (not the SD card) and you put it in USB 3 mode which momentarily deactivates data connection. When writing to your external card however, you are better off leaving it on the MTP USB 2 mode because you will not get the benefit of the USB 3 speed that way..
Yeah, I charged my phone for a bit when plugged into my USB3 and it DEFINITELY charged faster than any USB port ever has...
Charging time incorrect.

The phone does not charge from 0-100 in 1 hour. If it charged in 1 hour then that means that the charger would charge it at 3200mah. The charger only charges at 1800 max, not even a full 2 amps. Thats if the screen is off the whole time. Which is around double the time, 2 hours. If the screen is on it only charges at 1200mah. which would take over 3 hours to charge.

HI,
does the i9000 Galaxy S support the quick/fast charge from battery charging spec. 1.1?
My new pc mainboard does support this via software/driver. And allows to load with up to 1,5A
I couldn't find information on that.
The i9000 is USB 2.0 not USB 3.0, so the answer is no.
not exactly correct
as it does charge faster with a higher AMP output charger.
i use a 2 Ah or 2000 mAh charger in my car and the phone does accept the faster / quick charge
so if your PC has the option to do the higher 1.5 Ah output, it will take it just fine
just like if you have a 1200 mAh wall charger as some people here uses.
I installed the asus driver which installs a service and the aicharger.sys
I restarted.
They tray shows an icon with a plug, but it is crossed. Like disconnected.
I pluged in the i9000 via the usb2.0 port an no changes.
I then pluged the phone in to a usb3.0 port but the icon still shows disconnected (or ai-charging off)
Any ideas?

This is the bit that is not exactly correct. Regardless of how the hardware is set up it's up to the phone driver to request a powersupply from the computer. As it is the Galaxy only requests only 2 unit loads (200mA) from the computer, no where near the 500mA max of the USB2.0
So no simply plugging in a more capable computer won't change a thing.
interesting.
Are there any mods or fixes to support more usb power while connected to a pc?
None that I have seen.
ok, so the only possibility to charge faster is, to get an after market 3rd party wall plug with higher current than 700ma?

Interesting. So does the SGS actually use all of the 700mA out of the stock factory charger? If I use my 2.1 A charger could I overheat the battery?
Ok I've had it with the speculation. I've got a USB micro socket and plug on order and I'm going to make a pass through cable and measure the 4 different chargers I have here at the moment this weekend so we can put this one to rest
Stay Tunes.
Ok did a test. No the SGS does not use all 700mA. It uses 470mA. Charging is faster from the dedicated charger than the computer. I verified that the phone only draws less than 100mA from the computer socket.

Thank you.
But can I get more current from my PC with ASUS ai Charge?
I installed the driver but the icon in the tray doesn't recognize my Samsung.
That is because it doesn't have something an Apple Product has.
Apple products get more current with that driver/software thing. But the i9000 doesn't work with it.
in the past i checked if it is possible to charge the battery faster, and not Necessarily through the phone.
i asked a guy who works with electronics and he simply explained that everything is possible, even charging the battery to full in a few minutes, but it WILL kill the battery very fast...
yeah i installed to anticipate a quick charge...but all i get is icon with a big cross...
deleting it now......its useless to me...

Everything is possible when you charge the battery itself directly, but not when you charge through the phone. The phone is the charger. The computer and the wall plug only provide power to the phone. Unless you go in with a soldering iron there's nothing you can do to speed up the charge beyond what the Samsung wall adapter gives you.
Anyone else having this issue? Went from completely dead 0% to now 17% in 2 hours! Maybe it's a bad battery? Used to charge from 0% to full battery in about an hour or less

never use your micro usb cable connected to your computer to charge your phone. If your phone is ON and playing music or something else, that will still run down the battery even though it is connected to the computer. Your LG G2x charger that came with your phone is rated at 1 amp. The computer usb port is giving out a fraction of that. Even cheap chargers from China that are 350mA - 500mA will take forever to charge your phone. I use spare Blackberry chargers that are less than $5 and offer 700mA. They are great and cheap.

It's very similar to the TF101; it seems most Tegra devices use a charging cable more like USB 3.0 than 2.0, which pushes a lot more power and charges the device quickly but when plugged into a 2.0 port the charge slows to a crawl. USB 2.0 simply isn't designed to push the amount of power these newer devices require.
When I try this it will not charge my phone. I tried on several computers at home and work Pc's. It actually drains it.
I wonder why that happens???
Not a big deal.
No problem, I always have to take my charger everywhere I Goto be safe.
All computers using USB 2.0 or USB 2.0 add-on cards.

Yes, a fraction of 0.5. USB ports can provide up to 500mA.
I just charged mine at work using a USB cable plugged into my monitor. I noticed that trying to charge it off my laptop doesn't seem to get me anywhere. It might require using a powered hub or something similar to get enough juice.
I usually slowly lose charge when plugged into the usb at work. Granted the screen is almost always on and the phone being used.
I've noticed the charge rate for differs depending on the usb charger rating.
For example, on my laptop usb, it charges very very slowly. but when plugged into my desktop, it charges just very slowly. So they must have different current ratings.
When using my eee transformer usb plug ([email protected]), it charges the phone very fast, like under 2hrs. When using a usb charger meant for a blueant headset ([email protected]), it takes like 4hrs to charge. Think the stock charger is at [email protected]
I use Battery monitor app to monitor my batt usage/drain. Haven't really paid attention to the battery gain, but from looking at past history graph, think when plugged into the laptop, it supplied like 5-15ma of juice. When plugged into destop it looks like at 55-400ma. The transformer usb provides up to 1200ish ma, and the stock gives 800ish ma.
Now does using different rating chargers affect the battery discharge rate and health of the battery?
Just because a USB port on a PC says it'll output 500ma doesn't mean it will, it's all up to the software. If your PC or phone is cranky and doesn't communicate properly, your computer's USB port will default to 100ma, and you can't charge off that
Mine charges fine on USB unless I'm trying to use it, then it is pretty much break even.
I have just got my p6200 3g from malaysia. Couldnt be more satisfied. I feel like I just opened the only present I wanted on Christmas morning and its better than I hoped. Of course this came with an international gigantic 3 pronged charger adapter. I have (2) 2amp 5 volt adapters I was using for my dell streak 7. I tried them both and still get the red X. However when powered off, the device shows the battery charging animation. In settings menu it says battery state..discharging. I have ordered one from amazon due any day now, supposedly works with all versions of gtabs including 7.0+. Am I getting a trickle charge or is this due to not being a samsung charger? Im using the supplied samsung cable and outlet is capable of 2amps 5 volts.. please help! thank you!
the big 3 prong plug says 2.5 amp 250V? come on this thing cant need all that.. what does this batt need to charge??
##nevermind, I have the charger, just need the 2 prong USA adapter, hopefully I can find one. anyone have any ideas?
The red X is indeed due to not being a Samsung charger. Samsung tablets look for D+ and D- to be tied together and floating at around 1.2 volts or so. If they see anything else (such as the voltages that iPad chargers put on D+ and D-), they'll assume a USB connection and not charge.

To my knowledge, all Galaxy Tab variants use the same method of signaling a "dumb" charger. So any Samsung charger intended for a Tab should work - see my previous post for details.

hi,
i have the p6200 version of the galaxy tab plus, came with a usb cable and an outlet charger that connects to usb cable. when charging on outlet, it charges fine, but when i connect the tablet to my sony laptop, it says MTP instead of USB connection and there is a red X on the battery icon of my tablet, it's also not charging. how do i get my p6200 to charge on usb connected to my laptop? thanks!

It will and does. I've done it, it just charges MUCH slower and if you use it while plugged in too much it will drain at a slower rate than if you didn't have it plugged in. I was backing up my tab and the battery was at 50%, I plugged it into my computer and by the time the backup was done (nearly 16GB full) it was at 70% (took 2 hours)
Buy one of these: http://www.dealextreme.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
Set it to charge mode, plug between cable and charger (be it a computer or an otherwise not supported USB charger) and it will charge

My Galaxy tab 2 (GT-P1000) will not charge while it is on. I get the same charging icon with the red X. I am using the original cord that came with the tablet. Only when I turn off the tablet will it charge on the cord. The USB still works fine for connection to Kies. I just can't charge it normally. Any suggestions.
Also, I have been unable to sync my tablet so that my music, video, and pictures are available through the "video" and "music" icons on the desktop. I can play the files individually, but haven't been able to add them to the right library for these media players. What am I doing wrong? LOL

I believe you are asking in the wrong forum. This is the Galaxy Tab 7.0plus (GT-P62XX) area. You should ask in the GT2 section or the original GT forum (the model number you posted is the first Galaxy Tab). The fact that you have the product naming mixed up tells me you may have reading comprehension problems
Anyway. You are not being descriptive enough of your issue with usb charging. Are you using the Tab's charger? If not, it will charge really slow if at all (you didn't read this thread at all, did you?).
Also, You can't (AFAIK) play files directly off your Tab connected to a computer via MTP. It would have to be mounted as an external drive for the computer to use it as such.
How is the 3.0 usb working on this tab? Any problems with it?

If it works like the N3's charging isn't affected. And higher transfer speeds are only to USB 3.0-equipped Windows PCs.
The Galaxy Note 3 ships with USB 3.0, unfortunately at least in its current state it doesn't seem to get any benefit from the interface. Although the internal eMMC is capable of being read from at ~100MB/s, sustained transfers from the device over adb averaged around 30MB/s regardless of whether or not I connected the Note 3 to a USB 2.0 or 3.0 host.
Update: USB 3.0 does work on the Note 3, but only when connected to a Windows PC with USB 3.0. Doing so brings up a new option in the "USB Computer Connection" picker with USB 3.0 as an option. Ticking this alerts you that using USB 3.0 might interfere with calls and data, but then switches over. Connection transfer speed is indeed faster in this mode as well, like you'd expect.
Charging is an interesting story on the Note 3, but primarily because of what doesn’t change. The Note 3 continues to use Samsung’s tablet charging specification and charger, which has 2 amps of maximum output. The Note 3 draws 2 amps over a considerable amount of the charging curve, like other Samsung devices (in the linear part of the charge curve). USB 3.0 doesn’t change things up here quite yet with the new supported charge voltages that are coming eventually with the power delivery specification.
http://www.anandtech.com/show/7376/samsung-galaxy-note-3-review/3
Somewhere (maybe in the user guide?!) in the specification of the Note Pro 12.2 you can read something about a maximum charging time of 4 hours. To get this charging time you need a minimum of 2,5 A. What is the specification of the power plug?
On an USB3 host (PC, Laptop...) you only get a maximum current of 900 mA, maybe a bit more sometimes. With this current the charging time should be easily over 12 hours.

Slower or faster than the 10.1 2014?
USB 3.0 works just fine. Read/Write speeds have easily been over 30MB/s, with peaks around 40 or so. That's with the Sandisk 64GB MicroSD Class 10 card I have installed, which is really the "bottleneck." It's noticeably faster using internal storage and much closer to max USB 3.0 speeds, especially when reading.
Also FYI, the included charger has an Output of 5.3V / 2.0A. Which is 10.6 Watt.
Keep in mind that the tablet can easily draw more power than either USB 2.0 or 3.0 can provide, while in use. USB is 0.5A and USB 3.0 0.9A. Using the included 2.0A charger is your best bet.
I just let mine charge up over night, so I'm not really watching it or anything. I haven't gotten anywhere close to killing the battery, but I also haven't put it through "all day" heavy use yet.
I am running GSAM, so we'll see how things look soon enough.
Hey folks. I have noticed since I got the S5 a few weeks back that it charges mega slowly on anything but the supplied cable and power adapter. When I plug it in with the regular cable to my USB 3.0 laptop in high performance mode, it still charges incredibly slowly. even if I use the regular wall adapter but with a micro-usb 2.0 cable, it still charges very slowly. Is this an issue that I can fix, or do I need to accept that the standard charger setup is the only way to really charge the phone?
What is the Amp output rating of the chargers you are using? The Samsung supplied charger is 2.0
For some reason this phone charges faster than any other phone I've had.
Especially with the supplied charger!
I'm not sure what would cause yours to be slow?
I think it depends on your definition of slow... A computer using USB 3 with a USB 3 cable generally charges at about 1 amp. Use a USB 2 cable and that drops. Same with using the USB 2 cables vs USB 3 cables. Optimal performance is achieved with the factory setup because it is using a 2 amp charger with USB 3 cable. Anything less is going to be slower. Like I said though it just depends on how slow. A bit slower than an s4, under those conditions, would be normal because of the battery increase. A huge time difference would mean something is wrong. But if you are comparing just the factory setup with the other options you can't. That would be apples to oranges.
If I missed something I apologize. Been at work for about 30 hours straight
