I usually charge my Note 4 with a USB cable connected to my office PC when I'm at work and I use the stock fast charging adapter with included cable when I'm at home.
I've got issues with fast charging, with option setted on of course. My note 4 doesn't detect fast charging adapter and starts to charge slowly. I need to disconnect and reconnect USB cable to make it works, better if I do it from the adapter itself. In this way I can get Fast Charging notification on my status bar.
Am I the only one? What should I do?
Im also facing this issue.Seems like problem with the adapter.Will try a few days,if it persists,I will move to samsung care

shouldn't a 1.5Amp adapter be used for fast charging? I think the standard .075Amp and 1.0Amp don't have enough power.

Went to local electronic store and rigged up a mod for laptop charging, it basically charges with any usb port. Time to make a few spares .
one thing in the laptop it wont transfer data but it charges with my 1 dollar cigarette charger lol
why was this needed?
(new to tablets, waiting for an HTC tablet)
The tab doesn't charge when connected to a PC.
Any tutorials on how to make and items needed?

Interesting... Why is that?
are those resistors connected on pin 2 and 3? or better yet... got diagram?
The tab needs a power source that produces 5v @ 2 amps before it will charge properly.
Mine charges fine with my laptop...I beleive it only trickle charges, alot slower then the wall plugin, but it does charge.
wow 2 amps?
USB spec is max 5v 500mAh or 500mw? (2.5w ~) ? ... confused.
USB will charge the tab. However charge time is much longer due to lower USB power output.
When I go to Menu>Settings>About Tab> Status it says it isn't charging when it is connected to my laptop and the battery icon has the lightning bolt charging symbol but has an 'x' next to it so I assumed it was telling me the truth. BTW what clock widget is that in the OP picture?

While that is the USB spec for devices that are intended to use USB for data, occasionally you run into devices that will trickle charge off a 500mA connection but require a higher amp connection, usually provided by a specific wall wart plug, to rapid charge. The iPad had a similar function/issue if I'm not mistaken.

The galaxy tab charges just fine through usb connection on a pc or laptop, if ur doesn't u have two things to check, first are u using a usb2.0 or higher port and is your device set for usb storage file transfer, u can check in settings while connected to a pc or laptop, I charge my tab almost everyday using my pc as I transfer a lot of files daily, I don't even notice a difference in charge times compared to charging via an electrical outlet.

Hi, everybody.
i just buy a samsung galaxy tab 7.7 and just noticed only can be charged by using the power socket provided by samsung.
now i found a way to charge your tab by your laptop or PC through samsung STANDARD USB DATA CABLE cable.
First, download the software (ASUS Ai Charger) attached:
Second, just install and enjoy to charge your tablet through use cable.
FYI, battery indicator still showing no charging but actually it is charging.
you can check after one minute by viwing the remaining power up.
Thanks.
Is this software just raise yr usb port mah to certain amount?
If so, will this harm the computer?

My tab charges when plugged into my computer without that (or any similar software, only Kies and AOSP USB drivers installed). It doesn't show charging but the charge definitely goes up. Does that software actually make it charge faster? I have to say, I'm pretty dubious.
I would recommended getting the following adapter, I originally bought it for my original tab and was able to charge via the laptop with no problem. It charges as fast as the wall charger.

my tablet is charged well.
Thanks
Thanks for the info.
Though it must be noted that you need an Asus motherboard for this, my Gigabyte provides 1A front USB ports thats where I charge the Tab7.7 I'll try if there is any difference real world difference if I plug it into one of the regular USB ports.
I accidentally found out I was able to charge from my Mac without using this special software as follow:
I bought an external battery, New Trent IMP99D (Amazon Link) and it came with a special USB extension cable (picture below) that is designed for the Tab 10.1. If I plug the GT7+ directly to the IMP99D without using the extension cable, NO charging takes place. However, if I use the extension cable, charging works.
I connect the extension cable to my MacBook Air, connect the GT7+ charging cable and the tablet and... VOILA.. it's charging! HoneyComb even reported that it is an "AC Charging" and it charge pretty fast.
So you can either
a). Buy the battery and it comes with the cable
b). Buy JUST THE CABLE, model IMP44B (manufacturer link here)

I've ordered thus one. will see uf will charge the 6800 with the 30pin cable to computer usb...
If you just want to charge via pc you can turn off your device, this way will work.

I recharge the battery using my pc all the time... just connect it with the USB cable and that's it... no software or anything like that... The tablet battery Icon does have a strange X on it but it still charges the phone (AHHuummm, Tablet) just like the electric plug thingy...
Anyone got the same issue?
I cannot charge my G2 via PC or laptop USB. I am using a different cable though.
I've read somewhere that the needed output for a charger to work is 2.0amp, but this is already a USB connected to a computer!
If the charging doesn't work, that means i cannot connect it to the PC at all since it was never detected.
Is it the cable that has problems? This cable that I was using was still working perfectly fine yesterday with my other phone though.
Unless it is usb 1.0 it should only be the cable

computer and car charger not working
Me and the wife have LG G2 from Verizon and our phones will not charge from the computer or using our car chargers. Also, two of my 3rd party wall chargers will not put any charge on it. It thinks it is charging, but it doesn't and the percentage continues to drop. Very disappointing.

I don't know where you got the 2.0 amp from, but it's wrong. The charger that comes with the phone is only 1.8 amps, so you don't need a minimum 2.0 amps to charge the phone. If you plug in a lower amperage cable, you should get a warning that it will take longer to charge and you should use the charger that came with the phone. Haven't tried plugging into my pc yet. I should probably do that now to transfer some ringtones....
The Note 3 is the first phone to come with USB 3.0 support, the cable and connector are up to spec.
What I'm wondering if this helps with the charging speed, as the wall charger doesn't seem to be with a USB 3.0 connector.
Does anyone have any insight to this?

The wall charger has a 2Ah power output while a pc usb 3.0 port has a maximum output of 900mAh. If you use an USB 2.0 port it's only 500mAh.
The best way to recharge the Note 3 is to use the wall charger.

From a dedicated charger the final charging current is normally determined by the PHONE + CHARGER based on how the phone "recognizes" the charger as good/bad (and what battery level you already have + how warm the battery is) and how much power the charger can provide. I believe the max that I have seen on my Note 3 was 1800 mA (which worked with both USB3 cables but also with some good USB2 cables).
From a PC the charging current is the result of a more complex negotiation, the phone can still have "the last word" but it can not go over 500 mA on USB2 or 900 mA on USB3.
Somehow related - please note that on USB3 DATA you STILL need to MANUALLY enable USB3 mode EVERY TIME YOU PLUG TO THE PC. Even if enabled the mode will be reset to USB2 in 10 minutes and lost if you remove and plug-in again. That being said on my Thinkpad I have not seen it charging over 450 mA even when on USB3 under Win7 (but the speed difference exists, so USB3 is correctly triggered).
Also please note that the life of the battery can be heavily influenced by the charging current - the smaller the charging current the more cycles the battery will last on the very long term. Also high temperatures are pretty bad for the battery. So if you are in no hurry it is always better to charge with a small USB2 current that is guaranteed to not go over 500 mA.
Maybe I wasn't clear enough, I'm wondering if the wall charger is utilizing the USB 3.0 capability, and if there's any advantage of using the USB 3 cable over a regular micro USB cable.

No, there is not. The Note 3 has a USB 3.0 port, but it is only faster for data transfer. Charging is done at 2.0 speed, not 3.0. Regardless of what you attach it to, it charges just as fast as a 2.0 device.

What if you used a USB 2.0 cable with the 2Ah AC adapter? Would it still charge in "USB 3.0" mode and not give you a message to use a USB 3.0 cable?
I have my old 1Ah car charger and when I use a USB 2.0 cable, the phone says to use the USB 3.0 cable for faster charging.
But, looking at this pinout:
http://commons.wikimedia.org/wiki/File:USB_3.0_Micro_B_plug.PNG
It seems like only the USB 2.0 section is providing the power?
It's utterly confusing. Would be nice if someone who really knows this stuff explain how it works?

What's strange is that I have a car charger that is 1.0Ah. When I use a USB 2.0 cable, the phone tells me to use a USB 3.0 cable for faster charging.
When I use a USB 3.0 cable, the message does not appear.
But I'm thinking that the car charger can only put out 1.0Ah regardless of the cable that is used?
- Tried on All my PC's USB Port ( both USB 2 and 3 ports )
- Tried using Original Samsung Galaxy Note 5 Cable
- Bought and tested Aukey and Anker USB cables from amazon
- Bought new Original Samsung Note 4 Battery
- Charges around 2-4% an hour @ PC , so download an app "Ampere" , it states that i'm only getting around 80-120ma
- All cables works perfectly fine on the power outlet.. both standard and fast charge method
- Data Transfer is also fast
So my PC is probably the culprit ? but all other USB Devices works fine ATM

It's weird i know but you trying the usb cords. like you said pc, any major dust build up in the ports i have seen issues like this but just cant remember what the fix was.
You aren't going to get the fastest charging speeds when charging your mobile device via a computer's USB port.

Really? I didn't think you could. I know for a fact that fast chargers have the ability to charge a device using a higher voltage and amperage than a regular charger. I didn't think that fast charging via the USB port of a computer is possible.

Okay, go to asus site and see -mobo model sabertooth 990fx r2.0( it actually for iphone,ipod, but work fine with my gsn4)
When said 'fast charging' i mean it faster than normal USB charging(but ofc not same like regual Fast Charging 2.0)
I cant remember,but it show me 800-1000ma
*bad eng sorry
