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
how can u disable the usb charging? even if its in mass storage mode its keeps on charging.. pls help..
What's wrong with the phone charging?
Isn't it a good thing?
Charge properly
You wouldn’t think that there is a particular technique to plugging your Galaxy S 2 in to charge – and you’d be right. However, you should pay attention to when you charge. If you’re constantly topping up your phone’s battery whenever you get the opportunity, you won’t be doing it any favours.

Constant charging to 100% is actually bad for the battery, if you stop the charging at 90% your battery will live twice as long, with only a 10% drop in runtime.
I had an Motorola defy, and i am sure you could select not to charge the battery, when connected to your computer.
I'm also interested in the initial question...and my reason: if i connect my s2 with the mass-storage capable usb-port of a Samsung TV for viewing photos directly through the Media Player from the TV, i get an error from it saying too much current on usb because of the charging
so - how to avoid this?
A standard tv usb port does not provide enough power to charge the S2, you need a special adaptor that you plug you S2 charger into to provide extra power, see link below.
New Samsung TV`s don't know when, will provide more power to the usb ports so you will not need the charger in the future.

You guys are thinking of NiMh batteries, not Li+ batteries.
Li+ prefers a full charge, does not have a memory effect. If it stays at low power levels 10% it damages the batteries.
Li+ batteries have around 3000 to 5000 deep charge cycle, a deep charge is when you use to around 10% then charge.
It however has more than 2,000,000 micro charge cycles. Meaning you charge it at around 40%~80%
Battery has a cell life span, which means it is going to break regardless how you use it in 2 yrs time.
As for charging via TV, yes, you need a special cable, but that's for HDMI, not USB. The HDMI port is also the USB port on the phone. Standard USB Port supplies 5V 500mA, however, some Computers and Electrical Appliances with a USB port supply different amounts, depending on design.
Computers can supply 5V 1000mA, TVs might supply 5V but less than 500mA. Media Boxes might supply 5V but less than 500mA. Some USB chargers might supply 5V 1000mA but do not have signal in data+ data- lines, which causes the phone to lag while charging.
WIKIPEDIA KNOWS EVERYTHING. Wiki it, it will tell you it is true.. LOL!
so its oki if you plug the s2 to ur pc anytime and charge it anytime?
Pretty much.
I already got an adapter for connection via hdmi, but i forgot and tried to connect as mass-storage. Thought there might be a trick...
Has anyone noticed that phone does not charge while using GPS. The charging indicator is on but when I look at the stats it says discharging at -450 mAh. Is this the way it is and if so, is there a fix? 1 hr 42 m with 73% display on battery use and 43% charge remaining, but was plugged in the entire time while driving under an hour home. I am using the same Motorola high performance charger that every other phone is charged fully even when using GPS.
are you absolutely sure the charger is giving the full 1A?
What sensor app are you using to see the battery discharging?
Mine charges normally with gps on.

I was curious so I tested this with "Battery Monitor" I have it plugged into my laptop currently which only gives +500mA. and not the +1A that you get from a wall/car/high power usb port.
the app is showing +257mA with GPS on and functioning normally.
So charging good here... Might be something with your motorola charger? It could have a sensor in it to detect 'trickle charging mode' that is improperly engaging when connected to the HTC causing the charger to put out a minimal 'sustain only' level of amperage.
good luck!
you need a charger putting out 1A ... most car chargers put out 500mA so find a good one off monoprice
Here's what I'm doing. I have a Belkin 2.1A(2100mAh) USB car charger dongle. The problem is, once i connect the USB cable to it the phone registers it as "Charging USB" and does notcharge anywhere near as fast(power-wise) as if the phone was registering it "Charging AC". I'm not keen on using a power inverter to get the full AC charge so instead i am going to go pick up a cheap micro USB cable, splice it open, then disconnect the data wires(green & white ones) & then tape it back up. By disconnecting the data wires, the phone will no longer think it's a USB connection and then charge via AC, getting the best charge possible.
that should work ^ if thats the problem
I've found that using the included USB cable with a Belkin dual port USB car charger allows the phone to charge as if it were plugged in to a wall. I'm guessing the included cable has a different layout than standard Micro USB cables.

I'm guessing that I have the same belkin dual port (2.1amp and 1amp ports) and the best I've seen out of it is about 250mah charging. This is using the supplied usb/micro hdmi whatever cord for the phone.
I have seen discharge rates off the charger of 750mah which is the highest I've seen on any phone. I'm guessing if you are using the nav on your phone with the screen on, it will probably still be using battery while plugged in.

Possible, but says AC charging in Battery Monitor widget. I will post a few pics.
Here are a few Pics. you can see a couple of things.
-Charger rated at 950 MA out. and no other phone I have owned lost a charge while driving including TBolt, Charge, Bionic.
-Shows as AC charging
- Spikes of good charging detected
Put on Normal power mode today on the way in. live wallpapers did not wrok, just flickered. 3G on vice 4G. Battery still went down, but above 90% on 40 minute drive in. Screen low but on. Bluetooth speaker.
Maybe it is the iBolt car mount. See review online. will try without dock this afternoon on my way home.

Pros: Options for different backs
Cons: Does not charge the phone while it is in use
Try playing pandora when the phone is 100 charged. After 45 minutes on the car mount (and yes it is plugged into a charger and all indicatros show it is charging) and the charge level is 84. Using the same charger but plugged into the phone, playing Pandora for 45 min starting charge level 68. Ending charge level is 100.
Yeah, something is telling that charger to not give you full juice

ok, drove home off the window mount and just on charger, all same except full brightness on screen.40 minute drive. came up 7% battery vice down from 100 to 43%. nedd a few trials to confirm, but looks like window mount is throttleing juice.

i have seen spurts up to 913 with GPS off and screen just turned on. Using battery monitor widget. Not on window mount, just charger.
I can confirm. The car dock will not charge your phone atleast not with the screen on and nothing else running but battery monitor widget.
I bought one and tested it extensively yesterday. I used a Verizon 1a charger and a generic 1a charger. With the dock and both chargerz the phone DIScharged(as in LOST battery power) at between 100ma and 200ma. Without the dock using the same chargers and changing nothing on the phone the phone charged at between 50a and 300ma.
I did the test several times to eliminate any random things the phone may have been doing in the background.
After doing that controlled test I played with it some more and no matter what I did I could not get a positive charge with the dock attached even in airplane mode with the screen backlight at minimum. Without the dock using the same chargers i ran Pandora and a police scanner both outputting through the phone speaker, gps, wifi, mobile all on, and screen on auto and still had a very small positive charge.
Moral of the story DO NOT BUY THIS DOCK unless you dont mind it just being a piece of plastic that holds your phone in place.
I wonder if there's a quick mod to it to get it working right. Like the soldering of the USB chargers I've seen.

I just went ahead and bought an extra battery so I wouldn't have to charge in the car. Only takes 20 seconds to pop in a new battery.
Can charge both batts while I sleep at night.

I was looking for a high current charger for my Android tablet and there was a review that talked about compatibility. Some of the high cap chargers appear to be designed for Apple products and the pin wiring is subtly different. So, on some non-Apple products, the charge is only recognized as a lower power, 500mah charger and the users reported that some devices would normally charge and others would not. Some of the dual port charges also split the power. The 2.1 amp port and the 1 amp port cannot be used at the same time, depending on what is plugged into them. This was also brand specific. I ordered the Amazon Basics 2.1 amp dual charger and will see how that works. I have noticed a difference in charge rates between my Motorola charger left over from the Blackberry and the Verizon OEM one. The VZW one is faster.
I do the same thing I have been doing since my Windows phone days.
I use the AC cord plugged into a 12v to AC adaptor(screen set to 100% bright and no timeout).
I drove 6 hours last week ruuning Google Maps/GPS & my battery was 100% charged when I got to my destination.

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
Sent from my SAMSUNG-SGH-I717 using XDA App
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.
