It takes me about 1-2 hours on a wall charger, 2 if it's fully flat. I always try to use the wall charger as it's much faster, but I will use USB attached to a computer if I have no other option.
wall charger is two times faster than the usb! one is at 1000 mA and the other is at 450mA by default. If you want to change that you should install custom kernel.
Usb3 should be detected and the full 900mAh used (which on some compuhers may cause the chipset to power down the port if other devices are plugged in

Hey guys i just wanted to knw if ur phone lasts the same when charging using the laptop and using the wall charger bcoz mine is nearly 60% ie. lasts 40% less when i charge using wall charger.
Does anybody else is facing this too ??
That's an interesting observation, ill have too check. Though the laptop would be a slow charge and a cleaner regulated current due to the power regulator in the laptop's charger

yeah laptop charging is nearly half or less than half speed of wall charging ..
there is no difference between AC or USB power from a PC, but charging it with a PC takes a lot more time, because your USB port has not the power/current
i usually always use the wall charger it came with. But i remember that sometimes when i use any other charger it either wont even recognize the cable or not charge at all specially car chargers
The beast? I got mine but haven't powered it up yet for charging purposes. There is no light indicator that tells you when its done.
Got mine yesterday and I charged via AC and it took about 3 hours to complete. After letting it drain over night after 8 hours of heavy usage, I'm charging via USB and it's taking forever. With it on and after 2 hours, it was only at 15%. Now turned it off and it's been 3 hours and it looks like 75%. BTW, press the power button once and the screen will show the batter gauge.
you should charge it while turned on and for 6 hours or more for 4-5 cycles. Let it go down to 5% for those 4-5 cycles. Do not let it turn off from lack of power.
That is from instructions I received from a third party battery which had these detailed instruction to maximize capacity. I am sure you will get 1000 different ways but that is what I use and have always had good battery life.

While powered off, you can hit the volume button to get a visual on the batter status.

This thing pretty much requires the cable that came with it to charge at full speed. Older MicroUSB cables charge at a much slower rate and are recognized as USB devices when plugged in. It must be because of the higher capacity battery. When you have the right cable plugged in, though, it charges pretty fast.
I'm noticing that even using the wall charger and the USB cable it came with, it's taking about an hour for the Note to charge only 15%. Anyone else noticing this? Is it normal that the first batch of charges takes this long (at that rate it would take 6+ hours to charge from 0-100%)?
My note charges very fast when I use the ac adapter and super slow when I use the us from my computer. About 1.5 hours on the ac and more than 3 hours on my pc's us

Its always a good idea to charge using the AC wall adapter. The USB port on a computer usually supplies ~.5A @ 5v to charge the phone, the included Samsung wall charger supplies double that with 1.0A @ 5v. That is the reason you see such a big difference in your charging times.
(Some computers now supply more than .5A through USB, but .5A is most common)
USB3.0 can supply 5.0v @ 950mA to charge, but the kernel isn't set up to take advantage of this, I'll see if I can change that (it would only affect charging while booted)
Just shy of the AC adapter for those of us with USB3 ports

I was excited reading this because my new laptop has a 3.0 port. However, I then remembered that my power brick for my laptop is kick ass and has a USB port that charges devices at 1A anyways. Haha.

So I got it down to 5% and then I plugged it in at around 8pm and at 11pm it was at 100%. Not bad, not great but seems about right. Now my question is I see a notification that battery is fully charged and to unplug charger but Im going to bed soon and am going to leave it plugged over night. Is this risking the battery in any way?

That would be the only use for my USB3.0 ports so far. Have yet to even need to utilize it.
The charger that comes with the Note can charge the battery in 3hours via ac. I wouldn't suggest to charge via usb, just because it's way too slow. Im using my playbook charger to charge my Note, Galaxy Nexus , and my bb 9900. This charger is 1.8a, it nearly charges 2x faster than the regular 1a that comes with most phones. Same thing for my car charger 2a, i even use my ipad charger to charge my iphone 4s and it's way faster!! Use more powerful chargers... Not more than 2a or your device might melt down!!

That's weird. I was under the impression that GS Note only accepts 1.0A of power. Well at least that's what it saids at the back of the phone. I've got an iPad charger that draws out 2.1A, maybe I should give that a try.
here's a weird one..
when using the wall charger that came w/ my phone, instead of charging the battery its actually draining it, the battery icon says its charging/plugged w/ power but after leaving it plugged in eventually it died out, but if i plug it in my pc it charges w/ no problem..
pls help me or enlighten me as to whats happening...
thanks in advance.
Strange. It should be the other way around. USB 2.0 sockets push 500mah which isnt enough to charge the S while the wall chargers provided are 800/850. Perhaps a dud socket? Try another and if not your charger is fúcked.
yeah, i think its my effin charger, i plugged it in a diff outlet still same, i tried using it to charge my iphone its not working as well. thanks for the help.

USB isnt enough to charge the SXS?
Stop spouting rubbish like that.
I charge my SXS with my PC's USB port all the time and it charges just fine.

For me it discharges faster than it charges. It may charge off yours but typically it'll be very slow or not at all. Some ports push more AFAIK, but the standard is 500max.
I also noticed that, if I have WiFi on, the phone actually discharges when connected to the PC (when used anyway).
I don't know how much current is provided though, never measured it.
If charging through USB is fine then it might be that the charger is shorting the battery + and - through some resistance.
Try another charger and see if it helps , and replace the faulty one. You don't want to break your battery.
On my laptop usb port it will charge just fine. Slower than the normal charger but it does work.
On my desktop pc otoh it drains more than it charges. So there probably is a difference in output on the usb ports.

If you were using "front ports" these are often underpowered compared to ones mounted on the mobo(back of case, or all laptop ones).
I connect my phone via my front ports and it charged just fine actually...
I am behind the computer quite a bit and my phone keeps its battery and charges when attached, even when I'm installing a bunch of apps (I tend to browse the market via my browser and pick up apps as i go) I still don't discharge...
It could be a voltage issue with your ports, but with my frontal ports I notice no problems...but anyways, this isn't about the ports, this is about the OP's charger.
To me, it seems like your charger is faulty.
Hi,
I wrote about a similar issue I was having with the phone discharging when connected to USB.
http://forum.xda-developers.com/showthread.php?t=1573336
From what I could tell in my tests that I did the issue is when the phone is connected to the PC and THEN the PC goes into Standby mode. Even on a powered USB hub the phone charging mechanism does not reset correctly and continue charging but begins discharging.
I would have loved if someone else could have tried to reproduce what I wrote in that thread but no one responded. For me the only solution is to charge directly with the AC power and not through the USB as my PC goes in and out of standby regularly.
Phone charghed with USB will drain batery faster then phone charged with wall charghed.
It was thread in xperia arc about that, the test bring that conlcution.
So i recomend to charge with wall for better batery efecienty.
Sry for language im little sleepy. :$

when i tether to my pc via pdanet, my phone's battery gradually drains(which i'm sure you guys experience also).
has anyone tried out this cable(or one like it)? does it prevent battery drain?

Yeah, but not as much as a normal charger. The thing is that when connected to PC, to my knowledge, the kernel limits the charge rate even more than the current limit that you get from the the normal charger.
Kernel limits current from wall to say 850mA, even if have a 2000mA charger.
Kernel limits current when connected to the PC to say 500mA, even if you have a Y cable with the power-only leg on a 2000mA charger.
Most USB ports can't even give more than 250mA, even though the USB spec states 5V, 500mA.
A Y cable would help you because it would let you get at or close to the kernel limited 500mA.

Yes the split cable helps a lot on computers with standard USB ports with 500mA power supply. My other computers have 1.5A USB ports, and those are able to charge just fine with the standard straight USB cable.
Coming from the Galaxy Nexus where I had Fast Charge via USB allowing me to pull 1A from the USB port vs the .5A. My Note2 is rooted, does anyone know how to enable this or do we need to wait for a cutom kernel? Thanks!
If you look at the included wall charger, it's rated at 2 Amps. So it may not need the fast charge option.
I think he's referring when hooking the USB to a computer. That is always a slower charge.
You need a custom kernel that supports it.

The Fast Charge enables the phone to pull more power out of a standard usb port connected a computer not a wall charger.
and forget what I just said because i never refreshed the page to see someone already said that. Thanks!
OK, then you'd have to wait for a custom kernel that would have the feature in it.
I use it on the GS3 with its wall charger. It cuts the charge time in half.
But I've never tried it with charging from a PC's USB 0.5A port.
