[Q] Charging as USB even though I'm using the wall original wall charger

Hi!
I bought my GNII a week ago and phone is awesome!
The only problem is it takes soooooooooo long to charge. I didn't assume that something was wrong yet since it is new. After charging for the third time and it's still slow, I searched for answers but came back empty. So I'm here hoping somebody could help at least so that I could do everything on my end before contacting my provider.
Here are some information:
1. Charger that I am using is the stock charger that came along with the phone. USB cable and Original Charger.
2. Phone is not rooted.
3. When I plug it using the wall charger (USB cable + Original Charger) it is being detected as USB instead of AC.
Hope somebody could help.
Thanks!

Why are there cables with fast charging and slow ones? is this normal?

No there aren't , the problem is with the defective 4 pin usb cable bundeld with few of our sets actually we need to have 5 pin cables for proper charging , had exactly the same problem with my s3 puechased a HTC usb cable after that my problem was gone for good.

Yep the one packed with it is usb3 which is a bit faster. The other one is usb2 which is a bit slower.

Hi! Some breakthrough. I charged my phone at the office using the wall charger and plugging it to a UPS and VIOLA!! It charged as AC!! Could you (or anybody) know why?

Root, flash a custom kernel which supports fast usb charging

will it charge like AC after flashing? Rooting it would be my last option since I just discovered it could charge as AC without rooting. The only problem is why it charges as USB on wall charger but AC on a UPS.

That kernel will charge at 900mA by default over a normal usb connection.
I flashed it rather that the sock kernel just for that reason, plus for me it gives improved battery life etc over the stock kernel. You can overclock also but I have no desire to do that with the Note 2 as its pleanty fast enough already.

Does anyone know off a kernel that actually has usb fast charging enabled in it ?

[Q] Very slow charging. why??

When i connect my galaxy note 2 to stock charger it shows that in my battery stats it's charging as USB not AC.
Well what's supposed to be the problem. is my charger broken or the usb port in my phone is damaged??

Are you using the stock charger with the stock USB cable? My note 2 was charging really slow until I realized that the USB extension cable I was using wasn't delivering enough juice.

Do you have another 2A charger/USB cable that you can test from? I use an HP Touchpad charger + cable because its 2A and has a long cable.

I just happen to experience the same thing. I have had my Note II for a couple of weeks now and it have always charged from almost empty to full in less than 2,5 hours. Today however, it's going really slow. I do not know why. I've tried everything I can think of. I juse only the stock charger. Also tried the Ipad charger - no luck. This seem to be a quite common problem.

Hmm, just as I thought, more and more of this should be coming in upcoming days. I lost two good night's sleep because of this. Anyway, this is what I have done and you guys SHOULD do.

first time ever i have faced this issue (slow charging) couple of days back. it was dropped to almost 1%/3min
I have simply reboot to recovery and wiped cache
Now it come back to normal 40%/hr.

I have discovered that the stock charging usb-cable only has 4 pins in the micro-usb end. It looks like on is missing, from the standard five-pins. Can anyone check your stock usbs and see if there are four or five pins, and report back? Thanks!

I've mentioned it on my topic, I'm sure you haven't read it. Look above.
Anyway, mine has 4 pins.

My cable got only 4 pins. The second from the right is missing if you have the USB logo up.

I found a huge variance in charging rates based on a combination of chargers and cables. Goes to show that the cable makes a huge difference. Here's my findings:
** Stock Charger (2A):
w/Stock Cable (4-pin) - 1698
w/Cable from another phone (5-pin) - 1698
w/Cable from battery pack (5-pin)- 1698
w/generic eBay cable (4-pin)- 100! - It didn't charge at all, even with screen off.
** iPhone Charger (1A):
w/Stock Cable (4-pin) - 1300
w/Cable from another phone (5-pin) - 1100
w/Cable from battery pack (5-pin) - 1300
w/generic eBay cable (4-pin) - 100!
** Car Charger (1A):
w/another generic eBay cable - 490

[Q] Slow Charge with Including USB3.0 Charger

So this is an update to a previous issue I had...
When I first got this phone, the included USB3.0 charger charged much faster than a standard microUSB charger. But then it stopped charging fast. It pretty much stopped charging at all really. Like maybe 1% battery added in like 20 minutes.
So I sent it into Samsung and they returned it saying they couldn't replace it because the wall adapter part was actually from a Note 2 which doesn't support the 3.0 wire (even though it was absolutely the one that came in the box). Once I got it back, I found a brand new set of the same wire and adapter (it was covered with the packing plastic wrap and all that stuff which is what makes me think it was actually a replacement). I plugged in my phone and it charged quick again for about a day. Then it went back to charging slow again.
I still need to get down to T-Mobile to see if they'll exchange the wall adapter which supposedly doesn't work with the USB3.0 cable even though both times it worked at first. It's their mistake but I have a hard time believing they'll own up to it... The model on the adapter by the way is EP-TA10JWE with an output of 5.3V 2.0A.
Assuming they don't exchange it... What do you guys think are my options here? I ordered a 3rd party USB3.0 cable from Amazon and that does the same super slow charging as this (and it didn't come with a different wall adapter anyway so it was kind of a stupid purchase on my part). I tried plugging the cable into a computer with USB3.0 and it didn't make a difference. Is there a different wall adapter that is known to work with the fast charging on this phone that I can buy? Is it AT ALL possible that the connector on my phone is the problem and I need a new phone? That would be terrible, but if it's something I need to do I will. It charges just fine and the same speed as any other phone when I use a microUSB cord and adapter like the one that came with my old S3.
Any thoughts?
Thanks

That's weird brother. I checked my charger and i have the same model number and mine charges extremely fast. Maybe it's a problem with the device it's self.

no not rooted (i was thinking about it and then this whole thing started)

I've noticed the same thing with mine ..and definently trickling on USB 2 .. I thought USB 3 was suppose to be all the hype about how it would do when u turn fast charge on in a rooted phone with custom kernel.. The charging is slower than my note 2 on USB 2..

its so weird that it DID charge faster for that first couple days (and again after I got the new one)... And I have 2 friends with Note 3's that say they charge faster than their previous phones (one of them had a Note 2).
I just don't know what to do...

The enhanced speed with USB 3.0 is for data transfer, not charging. Using a USB 2.0 or 3.0 will charge your phone at the same speed.

Well first of all, every review says it charges faster with the included 3.0 charger... So I don't see how you could be right about that... Not trying to argue, it's just that was one of the features that everyone talked about... And second of all, the 3.0 charger that came with it barely charges at all anyway anymore, so even if that was true, either the cable, adapter, or phone still has a problem... Phone charges fine, maybe 3 hours for 100% charge with a microUSB cable... About 1% in 10 minutes (that's as long as I can bring myself to bother testing the 3.0 charger for). And that's if the screens off. If the screen is on it actually just won't charge at all, it's like it drains quicker than it's charging with the screen on with that 3.0 cable... Again I say "cable" but it could be the cable or the adapter or the phone that's the problem... I'd love to find a way to figure out which it is...

For some reason the 3.0 charger charged lightening fast today ... Maybe the jedi ROM had to settle in for a few days maybe?

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.

warp charging issue

Warp charging doesn't go beyond 3.5Amps on ampere app causing slow charging rate shouldn't it give close to around 5.2Amps charging speed? Can anybody share their screenshot or is there a issue with my device

With Warp Charge there are several factors that come in to play. The charger itself, the USB Type-C Cable and your device.
Has Warp Charge ever worked on your device?
When the cable is connected do you see "Warp Charge" displayed on the screen?
Did the Ampere App ever show the maximum 5.9 amps or does it always show a maximum of 3.5 amps?
Are you using the original Warp Charge wall outlet adapter and original USB Type-C Cable?
If Warp Charge was working before, how long has it been since you last saw it work?
Have you modified the device at all?

Yes it was all working before I have earlier got 5.2 to 5.5 amps but from past couple of months it's been fixed at 3.5 amps now, and yes I have been using original warp charger provided and no haven't unlocked or rooted my device, could this be a problem with the device or any other fix for this?

Bought mine 2019-12 . few days ago (2020-03-30) warp charge stopped working, it still charged, but extremely slow like 40 percent an hour. When it was off i tried plugging in charger, but it started looping, it didn't boot to an animated picture with charging battery, but it still could boot into OS when power button was pressed. Did a factory reset, didn't help. Connecting to pc usb still recognizes it. Had a feeling it was a hardware error. Maybe fast charging module went bad.
Sent it for a warranty repair, got an answer that it will take more time because it was sent for an higher level service. I guess it's quite bad, it could be a motherboard fault.
I read on oneplus forums that quite a few people has a same issue.

Connect it to a pc, see if it is recognized. Mine stopped working & it was a bad USB Car port. It would still slow charge but no warp charge & no windows pc would recognize it connected

Hi! I have the same issue, only difference is that mine is sometimes charging at warp speed and most of the time at 3300 mAh "dash speed". Did you manage to see what the issue was?
