My phone will not stay in usb 3.0 mode. Is there a way to force it to stay in usb 3.0 mode? This makes a big difference in charging speed on my laptop. Almost 4 x the charging current is supplied in usb 3.0 mode.

4x the charging current? lol no. Try 2x at peak.
the problem is probably your laptop. why isn't it supplying the additional amperage for usb 2.0?

Save your lol. It depends on the computer. In USB 2.0, my computer is supplying 96 ma. In USB 3.0, the charging current 384 ma, which is 4x as much, as I stated previously.

I give up, why? Maybe it was designed that way. If I knew, I wouldn't be asking.

go to a laptop forum? the phone and the cable speed and phone have nothing to do with stock charging. usb 2.0 and usb 3.0 can both charge at "384ma" like you stated. your laptop just refuses to do so.

Charging at 384ma would take about 4 days to charge your phone. Check your currents and try again.

i was wondering does anyones a500 charge via the USB lead from their PC?
i seem to recall my tablet charging from usb the first day i got it, but then i plugged in an AC usb charger from wall socket into the usb port.... and now it no longer charges from my PC.
am i imagining the inital charge via usb - pc? did it ever come with this capeability or does anyone else's work like that and ive most likely fried some usb- pc - to charge component.
if no ones elses does im thinking that the more powerful battery in the a500 compared to say a phone pc-usb charger, the pc cannot draw enough power through a usb port, seeing as they only provide 5 +/- 0.25 volts, unless on an externally powered hub.
A standard USB connection does not provide enough power to charge this device, perhaps you are mistaken in thinking it did the first time. USB 3.0 may have enough output but I have not tried (no 3.0 on any of my machines) and don't know if anyone else has.
Cheers

There's a little sticker on the side of the case that says "INPUT 12V DC 1.5A"
That should tell you all you need to know. No way is USB going to be able to provide that.

The problem is that most people ignore the 12V part and look only at the Amps. And think, can't we just charge slower. Not realizing what a jump 5V to 12V is, thus threads like this will keep popping up.

Well duh. USB 3 is still 5 volts, it's just the amps they increased, to 900mA, which still falls short of the 1.5A required.

Is the nexus 4 capable of fast charging the battery via USB? I tried different kernels/ROMs, but the toggle is not working and a search on xda didn't answer my question.

It is capable, for example franco kernel now supports enabling it from his kernel app. Some of them requires a little more work where you have to enable it by writing to a file. Just depends on what Kernel your on.

Once you enable it you have unplug and plug in the cable. The fast charge only works when you're charging it on your computer and any USB port besides the wall outlet. When you do have fast charge enabled, the battery stats should read "XX% Charging (AC)" if fast charge is not enabled the parentheses should be (USB).

I actually have a question that may be off topic. Does the charging time matter whether you are using a USB 3.0 cable rather than a USB 2.0 cable or it doesn't matter cause the charging power depends on the adapter you use? Any chance that would help with Franco kernel?

It doesn't matter. The Nexus 4's charging port will draw the amount of power it needs and that's it. USB 2.0 and 3.0 are just data transfer speeds. No relation in charging devices.

And usually it'll draw lower and lower as it gets closer to full charge (ie: if you're at 20% you're more likely to pull 800mA off a 2.1A charger than at 75% and up [which tends to be around 500-600]), also factoring in the actual drain of the phone being on. The phone is pretty smart about not risking to overcharge itself.
Works perfectly with Franco kernel

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.
Can you use a regular micro usb charger in place of a 3.0 cable?
Thank you for the help
Yes, no problem. In fact with my S5 there is only a usb 2 cable supplied.

Just an FYI: The USB3 cable is in fact micro USB as well. It's just the USB3 version of microUSB. The USB3 port on the phone is backward compatible, so a USB2 cable will work just fine in there. :good:
Yep it will work

It's USB 3.0. You'll get faster data transfer speeds when plugged into a USB 3.0 port on a computer.

faster data transfer rate.
OK thanks.
So the charging rate is the same depending on the "block" amps?
I think the USB 3.0 charges faster even if it's still the same 2A charger

It would seem so, yes. In re: max charging amps, it seems that the S5, much like the Note 3, will charge only at 1200mA while the screen is on and 1800mA otherwise. See discussion here: http://forums.androidcentral.com/sa...48184-galaxy-note-3-max-charging-current.html
To the OP, thanks for starting the thread... I hadn't even realized that the new Micro USB 3.0 connector actually was backwards compatible with the older MicroUSB 2.0 for charging!
Great link thanks!

Just use the USB 3.0 charging cable. Not much else to do. The charging speed might be different for wall vs. computer.

What is the USB 3 charging cable? what kind of cable is included in the original package? I also suffers from slow charging, might be because I connected the USB cable to an iPhone usb adapter (because I have US plug, and i'm using EU).

It means that charging faster will reduce the overall life of your battery because the battery and phone doesn't support it. The Galaxy S5 supports USB 3.0 and Qualcomm Fast Charge.
Also, the fast charge on your Ace 2 just means that it will draw maximum power from USB ports. It doesn't change charge speed with a wall adapter.

Use the original cable and adapter. If you think that's too slow to charge, like taking up to 5 hours, that's unusual. Let your carrier or the store check it for you.

Hi. I have a G900F and I have noticed that my new S5 charges much slower than my old S3.
If I check it with "Galaxy Charging Current" or GSam Battery Monitor" it says that only 450mA is used even though I have connected the phone to my Laptop using a USB3.0 cable on a USB3.0 port.....
Any advice please. Thank you!
