After about two months of using the Note 4 every charger i use, be it AC or USB the phone reads it as USB. I have tried so many chargers with no luck. Anyone have a solution?

Got my Verizon gnex a couple weeks ago. I have a habit of just charging it every night that has carried over from my Droid incredible 2. But on the off chance that I am charging before 9:30 or 10, I have noticed that it charges incredibly slowly and actually drains while browsing the Web with WiFi. I have been using an older cable, is there some new micro usb voltage or something? Are you experiencing similar charge speeds?
Any input is appreciated. Thanks in advance.

Charging off the wall plug or a USB port on a computer? USB ports will at the most put out 500mA at the port, with some line loss via the cable you won't charge barely at all. Most wall chargers are 1A, and will charge faster. An old cable can't be helping with that either.

First of all, if it drains while using and charging it at the same time, then this can cause plenty of battery issues. I've charged my Nexus on low voltage circuits, such as the ones on many ferries and while there are no immediate problems with it, once I fully charged Nexus when home and used it the next work day I had problems. Once the phone had discharged to the range it was when I was charging and using, it completely froze and after restart had lost ~20% battery charge.
So it's never recommended to use the device while charging it with low voltage (this can be the case also when charging through your computer).
It's recommended to charge the device through a wall outlet and (possibly) with the official charger that came with the product (or one with same parameters).
I always use a HTC usb cable and iPad charger for my note 2 and they work perfectly.
But today when I use them to charge my note 2, I find it charging very slowly.
I check the batter status and find it is USB charging while I use the wall charger.
I plug it out and plug in again , the problem remains.
Resolution: When I restart my Note 2 and use another cable , it turns back to AC cable.
But I don't know which one is faulty? My phone or my cable?
My phone: stand by for 17 days and I didn't charge it cuz I only use this to answer phone calls.
My cable: no physical damage and use perfectly before, though I use it with other devices.
what's more: After I use another USB cable , I try the previous one again and it works well ...
I don't know why.
Is it happening to you guys as well? Is it gonna harm my note 2?
Hey all. I finally got my Note 3. I have been using it for a couple of days and, of course, it is awesome. But one thing is troubling me. I charge my phone via my desktop PC, which has several USB 3.0 ports. I first plugged it into the ones on the front, and it wasn't charging very quickly, so I plugged it into one of the back ports, and i'm still having the same problem.
For example, last night, I plugged it in around 1am at about 30%. It's now 7:30am and its at 96%. I would have figured it would be at 100 a while ago. I am using the original Samsung USB 3.0 cable that came with the phone.
I'll have to do a more scientific charging test to see what's going on, but has anyone else seen this?
The supplied charger puts out 2 amps. Which is much higher than any USB port on a PC will ever provide. That's why you're seeing such large disparities with charging rates.

A computer's USB 3.0 port is only spec'd to put out up to 0.9amps, compared to 0.5amps for the older USB 2.0, but the A/C charger puts out 2amps, so use that when charging time matters. I never use a computer's usb port for anything anymore except adb sideloading in recovery (where adb over wireless won't work). Note that SOME computers do have non-standard higher amp usb ports, but it's not that common.
ah I was also wondering why the charger itself charges the phone much faster than my desktop. Good info, thanks guys!
I have bought this item from ebay, it work great and charge the phone very fast

Thanks for the responses people. I will use the plug from now on.
The charging speed will definitely slower than..?
It is the normal case that the speed will be much slower when you charge a device such as your Note3 via USB than via DC Power Supply. USB is mainly designed for the communication. The standard charging current of many mobile phones is 1 A or higher. But the highest output current of USB cable is only 0.5 A which could not reach the source demand of a phone. Except for this, we do not recommend charging via USB because the unstable current output can easily reduce the battery life of your Note 3.:laugh:
hi, does anyone have a solution. when i plug my note 3 7" in it doesn't even register as being plugged in. do other roms correct this problem? or is there another solution. I've tried different plugs with outputs that say they are the same as the wall outlets (which charges fine)
This is a major problem as i only got this tablet to replace my car stereo. I have everything done and wired up, but now I have a tablet that can't charge while in the car.
Any solution and I would be very grateful. thanks.

Sa, me issue. Nobody else care to use this as a GPS and not kill the battery?

Chances are your adapter isn't putting out enough amperage.
What is it rated for? The tablet really wants 2A, though it seems to work ok with 1A. That said, it also seems to be a bit funny about cables.
I only just got mine yesterday, so early days, but have noticed some charging weirdness.
My charger says 2.1A and is capable of charging an iPad. I tried 2 different cables, both data cables but they both work in a wall charger.
I was hoping someone would tell me to update to CM and all would work fine because there are some odd UI glitches in the touchwiz, especially bluetooth disconnecting.
I dont want to root and ROM unless I know these problems will go away. I will return this thing if the problem is unsolvable. I have about a week left.
hi guys.I used to charge my phone whole night so I did not really pay attention how much time it needed to charge full but for morning it was ready.so I decided yesterday to charge.it was evening and I noticed that it to very long time I unpluged it after maybe 4 hours and it was on 58%.Now I am charging it and it took more than 4 hours to reach 100%.have any ideas how can I fix it?battery life was 4 4.5 hours of screen usage lattely.can it be bocouse I used to leave it at night?
As you using a high power charger? Are you using home original Samsung USB cable?

I use original samsung charger 2.0A output.the usb cable is not samsungs.can it make such a huge difference?
They can may a difference, even when transferring files or flashing and chargingI don't have empirical data, it's just my personal experience with android phones over the years.
just pluged in my phone.trying another cable .hope it works

There are lots of different quality USB cables. I had a rubbish one that actually discharged instead of charging it was that bad.
Get different cables (try and borrow your friends' cables) and run the app Galaxy Charging Current from the play store. This will give a charge current trading for your cable/psu combination. If your psu is a genuine 2.0 Samsung charger then a good USB cable should charge at 1900mA. Rubbish ones can be anywhere from 100mA worse than charging over USB from a computer) upwards.

I checked all my chargers and cables.I found out that there were only 2 cables which were good enaugh to charge with.I have not tested it in full charge but I think problem solved.I just needed original cable thanks for help!
