Charging takes forever

I received my Epic yesterday, and so today I'm doing my first full charge. I've had it plugged in for almost three hours now, and I'm only at 50%. Is anyone else experiencing this?

are you charging it on the wall or on a pc? and are u using it alot while charging?

It's connected to my PC. And I'm not using it at all.

most USB are low power. You should use the wall charger the first time.

usb is slated to run at 500mAh, doesnt mean it cant go over it.. but thats what most of them do. ac charges at least 1000mAh..

Well that would explain it. Thanks!

ROFL, don't mean to be rude, but try reading the adaptor it comes with, the wall adapter is 700mah, lower than what came with my 3 year old blackberry, I'm using the wifes old cube from her iphone now, thats a full 1 amp.

Hm.. No wonder I noticed it took forever on the wall charger also.

Is there any advantage to having a lower power charger? If I could find a micro usb charger that provided 1 amp, would that detrimentally affect my device?

no it shouldn't, the thing has a 1500mah battery I believe. 1.5amps and less is fine. cablematters has a package for 5 bucks that has wall charger and car charger that are 1000 mah. and all IPHONES use 1000mah

The amperage is really just the max amount of power the charger will supply. Many times, the actual power draw will be lower than the maximum of the charger..

Chargers

Any risk in using a different charger than the original samsung one to charge the sgs2?
I use a combination of blackberry charger at work, universal micro usb charger downstairs at home, universal car charger and official charger upstairs.
Any concerns with this?

I've been doing that for ages. I use the droid, SE x10 and iPhone chargers with no issue.
As always YMMV

I am using htc's charger which has a higher rating than samsung charger. No problem at all...

I use a Sony charger to charge my S2 , I have not even removed the Samsung one from the box , As long as you use a branded charger will be fine.

I've tried to use Nokia's 1200 mA charger, It did charge the phone but whenever i connected that charger the phone would slow down terribly. So, whatever you use, try to keep it around Samsung's charger's 700 mA.

Ive found that the standard charger is rubbish! I had my galaxy s 4 month and it broke, my wifes galaxy 3 did same and now i dont even bother with the one out the box, just use the usb cable and the adapter i got with my tab.

Absolutely right...my phone is about 1 month old..and the official samsung charger is already broken..not charging anymore..i guess there is an internal wire breakage at the flexible point of the charger becoz when i shake the wire at that point it starts charging intermittently..

Same here. I tried all sorts to get it to work with no joy. I now have 3 duff samsung chargers that are potentially a fire hazard if left plugged in! Tempted to email samsung and raise this concern.

At home I use a Lenmar AC-to-USB 1A charger I picked up at Fry's for around $10; in the car I use a 1A Cygnett 12V-to-USB charger, also from Fry's. Both charge the device at least as well as the OEM AC charger; the car charger appears to charge the SGS2 even when I'm running CoPilot Live.

I use the iGO charge anywhere.
It's a tad pricey, but since the GS2 battery life isn't great (my only complaint on the phone), the charger is great for it since it has an internal battery that charges up when you put it in an outlet so you can charge the phone without needing an outlet. Great for in school or walking around, just put it in my bag and press the button and it charges.

I'm using my BlackBerry charger with no issues, I just do it for convenience as the charging time is the same as the standard charger.

Cheers for the replies, you have put my worried little mind at ease!

+1 .Just used the charger from a different brand and no bad feelings while using it

well, i just emailed samsung raising my concerns regarding the faulty chargers... see what they come back with....

Guys have you noticed any change in response when we plug in another charger?
I have been using the HTC charger, 200 mA (input), Output 5V --> 1A.
Whenever i connect my phone to charge and try to work on it, i see my screen lag terribly. Haven't tried it with the supplied charger though due to the low voltage that came with it.
I know i would be wrong, but wanted to check with the experts on this forum...

200ma is way low, less than half the 500 ma usb standard. Get a new charger. Most of the chargers you are going to see will be 500 ma I would go with double that.

Some (bad?) chargers will disable touchscreen
I have a couple of usb-chargers off ebay and they give some trouble.
When connected, the touchscreen will not work anymore.
This is mentioned in the manual btw.
Guess the SII is a little sensitive.

Yeah, ebay chargers are a crapshoot. Head to walmart or similar and read the power specs, get something that puts out 5v at 1A LPS. This will charge much faster than the often usb based standard 500 mA chargers and the battery will not be harmed at that charging level which is what many stock HTC chargers put out nowdays. Do not get anything less than 500mA, this is the usb standard and works but will be slower to charge. El Cheapo no name chargers on ebay and such may have the spec but may or may not actually put out the juice. You can usually tell this because the phone will have problems like the ones mentioned right here. The stock charger does not put out any special juice, juice is juice. If a charger puts out to spec the phone will work while charging.

Galaxy Note without original charger

Hello to everyone!
I have one simple question: do I risk something if I charge the Note with another charger than the original one?

I don-t know, but I think no.
I charged many time my note with htc charger and gs2 charger.

I almosr never use the original charger. I use the charger that came with the bluetooth headset and everything is fine

It doesn't matter what kind of charger you have. The only thing you must look at is the voltage of the source (5V DC) and it must be a micro usb plug

im using my old htc hd2 charger as the samsung one seems to have packed up and isnt charging properly

The easiest way to charge your Note is of course via a USB>Micro USB cord plugged into a laptop or PC (where you are guaranteed the voltage is correct), however if you are using a generic or knock off wall wart charger than provides a micro USB connector there is some small chance that it will not charge your Note.. look for the charging icon and if its not charging, toss the charger and get another.
There is no specific risk to the device, provided that it (the charger) has a micro-usb intended for charging generic devices..its just that some modern portable devices have a stricter requirement (tighter tolerance) for charging voltage and simply will not charge outside that voltage range.. my BB9930 does exactly this..

Since all micro/mini usb chargers have the same voltage, and vary only in the power output - the only problem you could face is slow charging, or no charging at all if the charger doesn't have enough juice. But it certainly won't harm the phone.

I'm using my old Nokia N900 charger without problems

I'm using an old HTC mains-to-USB and a Nokia microUSB cable...

My stock charger has a slight squeal, so I usually use the charger for my BB Curve 9300. Does totally fine.

My Note was purchased from expansys UK but shipped in from mainland Europe. As it was to be sold in the UK, expansys had to supply a UK adapter rather than an EU one ...I received an HTC adapter with my phone. At first, I was worried, but discovered that it works beautifully with my Note. Charges faster than generic Samsung chargers too! You should be fine using another standard charger

For the first 3 weeks I was using a blackberry (original) Bold II charger.
I noticed charge time was too long. And maybe even battery life was shorter.
Im not 100% sure about the second statement but the first is confirmed.
When I started using the Note charger it was faster. Not super fast compared to iPhone or iPad but faster than using the Bold charger.

I never use my samy charger..Im using my DHD charger..no problem at all..

Most modern USB chargers should be fine (I use my old iPhone charger for the Note, for example.) Watch the power output though - some tablet chargers are rated at 2A+ and that could overdrive your charging circuit and cause damage. If you make sure your charger is about 1A (and 5V, obviously) then you should be fine.

Well emuX said it all!
1A of output and 5V and you are fine!

Actually the charging current is limited by internal resistance of the battery, so the battery effectively "accepts" charge. Charging current is not "pushed" in by the charger...
obviously a charger from say a BB is likely to be current limited and so longer charging times would be expected, but an iPad charger will work fine.

I wouldnt worry too much, I charge my note with my iPhone charger purely because the USB port faces a different way so I can actually fit it on my plug extensions without loseing 2 sockets.
Pretty much anything with an output of 5Vdc and a minimum of 1A will do just fine.

car charger

Any idea why I can't seem to charge my Nexus 7 with my car charger?
i have both a generic Micro USB charger and I have one of the dual USB ports that you put into the cigarette lighter. It wont even acknowledge that I have plugged anything into it.
i have used the USB port to charge MANY different cell phones my old Dell Streak 7 and even a friends iPad.
Any ideas?

I think the N7 needs 2A to charge. a single USB is 500 mA and the dual 1A, so I don't think there's enough power.
Also check if the output of your microUSB cigarette charger is 2A

This one will work: http://www.amazon.com/gp/product/B0090SVY3K/ref=oh_details_o02_s00_i00
It charges at the same rate as the stock AC charger.

The N7 is one picky device for charging. I have several chargers for the car that charge the iPad but not one will charge the N7. Same as AC chargers. This set works for me

This is what I use and it works just fine. I use it to charge my N7, GNote, Nook Color or my grandsons IPhone and it works equally well on all of them.
BTW, it prime available if you are a member.

It only charges via usb when the screen is off or when the device is off. Try plugging it in checking the battery % leave it awhile and then recheck the battery % you may find its gone up!

We can only use the LG charger?

Since the battery life of the phone is quite poor it's only natural that i would like to charge it when i'm on class or with an usb cable when im using my laptop, using other usb chargers/cables, but on the manual says (of course) that we should only use it with the lg charger that comes in the box or an official nexus 4 charger .
It kinda sounds like bullsh*t until i remember what happened with my motorola milestone, sometimes when i used another charger the screen started doing crazy things, like swipping the homescreens by itself , oppening apps, until i charged it for at least a few minutes with the official charger, some months later my digitalizer died, so you can imagine how traumatized i am, but then i think what's the point of trying to make a standard out of microusb chargers if we can only use the official charger? what do you guys think?

I find battery life to be very good.
I have been using an old HTC charger on mine without issue though. I suspect the 'only use LG charger' is to cover themselves in case you kill the device with a cheap and badly made knock off.

Feel free to use any USB wallcharger you'll find.
I tried some i had laying around (HTC, iPhone 5, iPad) and they all charged without trouble.. :good:

Yeah, I've used a 1A HTC charger with no issue. I accidentally left my lg charger at a friends house and had to use what I had.

the battery life is good, better than s2 with its extended battery, i was wondering about this too as i want to use a sony rx100 at 2amps to charge while im traveling.
on page 168 of the service manual it states the max charging current is set at 900mah, over voltage protection upto 28volts

The current should be controlled by the phone, not the charger. Therefore there shouldn't be a problem with more powerful chargers. The voltage has to be correct, though

The phone certainly regulates the power it takes.
If you are really worried about the chargers just flip them over and read the output ratings. Most of them are exactly the same these days.

Any USB charger will work. Note the output current on the charger though, as that will impact how fast it can charge and whether or not you can have the screen on while you charge. The LG charger that comes with the phone is 5v 1.2a, an iPhone charger (at least as of the 4S when I got mine) is 5v 1a and an Amazon Kindle charger is 5v 0.85a. The USB 2.0 spec calls out a max power output of 5v 0.5a.

I'm confused , the lg nexus 4 charger is 5.0v 1.2A and my galaxy nexus charger which i use sometimes with my nexus 4 is 5.0V 1.0A , what does this mean? what's the difference?

My Nexus 4 is on the way so i cant comment on that but my Sony Xperia S acts differently to different USB leads even on the same charge unit. It might charge at 500mAh or 950mAh (on a charger rated at 850mAh), the screen might be fine or it might act erratic and it all depends on the lead plugged in to the charger

I used Samsung/blackberry chargers and they worked. Not sure if they were as efficient though.

I pretty much use anything but the LG charger and have been doing so over a month. So feel free to use any quality charger you like.
I also charge of my Philips Qi pad and off computer USB ports.
As long as it's providing stable power or anything close to it, it's good.
Just be careful with (fake) cheapo chargers. Those might cause issues with the touchscreen going haywire while charging off them. I've also read that about some car chargers, but so far my cheap 2A 2port USB car charger that came of DX is working fine for me.
YMMV of course. But there is no need to stick to just the LG charger.
