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. :$

^^ what he said. 5v and 2.0amps is like double the normal chargers... 2.0amp is crazy fast... from 32% to full in just under an hour
Yup I bought an extra one on Amazon because of how slow my old charger charges it. It's like trying to charge a laptop with a phone charger haha you need the more powerful charger. My car charger claims its 1amp too but I feel like it charges super fast too.

I have the same prob. Charged about 7% in 30 mins (using the supplied charger). Charges fine when I use my N7 charger though. I'm gonna have to check the charger when I get home.
Just for the hell of it, here is my how my charge is going right now:
7% - plugged in at 3:22
21% - 3:31
33% - 3:42
44% - 3:52
57% - 4:04
83% - 4:28
For what its worth I don't have this issue with charging - s4 charges comparable to s3 HOWEVER i am not using stock charging that came with the box, I am using cables i have had from before and sometimes even use the USB to wall plugs from Apple and/or BB or whatever I have had lying around - seems to work well.
With a 5V 2 amp charger it goes like a bat out of he'll, using my thunderbolt's 5V 1 amp charger it's quite slow.

i have noticed that having it plugged into either a car charger or a computer, it does NOT charge very quickly... not to the point where it is annoying but, slow enough to notice a difference...
If i take the cable from the box and plug it into my USB hub (it has it's own power source also) if im using it for much other then file transfers i can still lose power off battery. It just seems to slow the battery drain instead of just charging slower then plugged into the wall with the 5V 2amp plug. Now obviously if I'm not doing much with the phone while on the USB it will charge but much slower then the wall charging

That's to be expected when plugged into a source that's limited to 500 mA.

Bear in mind that the phone will charge faster using the stock cable than it will with other cables.

Same here...on stock charger my phone charges v3ry quickly. Are you rooted with special ROM? Are you using non samsung charger?

Ok, there's something else going on here. Maybe its software related.
My S4 will only charge fast on the supplied charger. The cable doesn't seem to matter; I tested a bunch of them. I have an assortment of other 2A chargers and none do better then barely keeping up with power useage; hardly any charging at all. Again, the usb cord doesn't seem to make any difference.
Now, I've read mention of a "fast charge" feature that the kernel developers are "turning on". I haven't found a good explanation of what exactly that means but it appears to me that Samsung tried to make the device only charge at the full rate using their chargers and at a minimal trickle charge rate for all others even if they are capable of the full 2A output.
Then there is the problem of buying extra Samsung chargers since there appear to be a lot of knock-offs that will not get the phone to charge at full rate.
What a stupid thing to be such a PITA.
Anyone have any solid info on this?
just about every samsumg device either needs a kernel hack or an adapter to get fast charge off of a non-samsung charger. you can grab a few of these:
http://dx.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
and use them with just about any 2amp charger with no problems on my old galaxy tablets or my galaxy note and nexus getting fast charge(nexus even charges faster on the 2amp - hope i don't blow it up!).
Fast charge from my understanding is just turning off the data connection when plugged into a computer. This allows for higher usb charge rates, it also helps certain wireless charging setups. I am coming from a gnex where this was the terminology, I assume it's similar. Fast charge shouldn't do much for you if you are having trouble with 2amp chargers, but maybe in this case Samsung limits through put when it doesn't recognize the charging unit? If fast charge tweaks somehow disable this, then I guess it's possible you would enjoy increase in charge rate though I have no verification on that.

Well, I have to discount my own theory. I have some off-brand adapter and cable to charge in my car that works great.
I sure would like to know what's going on with the chargers in my house.

There's a problem with semantics going on. Fast charge is exactly what you're used to it being on the GN. What's being referenced here is quick charge, a feature of later Snapdragon SoC's.
Sent from my Nexus 7 using Tapatalk HD
fast charging is rapid charge where near full power is transferred. in the gn2, gnote 10.1, gnex, and gtab10.1 the max i got was ~1600mA with all my 2.1A chargers including the samsung charger. the rapid charge continues to 90% and then switches to trickle - anywhere from 400-900mA til 100%. without the adapter you're stuck at trickle, even at under 90%. some chargers seem to have it built in to rapid charge,but most don't.
i've never gotten a full 2100mA from any charger yet.
you can find schematics on how to build your own adapter in one of these samsung boards. i think there was a very detailed one in the gnote10.1 forum.
Hello if anyone still has this phone do you have the same issue I got this phone last week (it does what I want and I am 12)it would not charge from a outlet but if I plug it in as a USB on my Wii it charges but it is so slow and I can't find a fix for it

This cable fixed it for me, buy a couple just in case the cable begins to fail (which they do). This cable increases in charge & charges to 100% fast while hitting the hotspot hard.

Try this charger too, it's 2.5 Amps vs the stock 2.0 Amps Charger, so using the above Premium High Quality USB Cable & This charger will ensure very powerful charging rate.
