Guys, I have my normal charger at home which works fine. Here at work I have a fairly new (but cheap) USB cable. At work the charge never goes up, it stays at the same percentage all day. It charged my Optimus 3D fine.
If I swap it for a colleagues USB cable (came with his Windows Phone) it charges fine (same USB port or USB ac adapter).
Is there a certain type of Micro USB cable I should be looking for that's not stupidly priced? (in the UK)
Coming from an Iphone I didn't have any spare micro USB cables so I went to a computer store and bought 3 store brand (cheap) microUSB cables and they all work fine.
The only thing to take note of is some wall charges are seen by the phone as "USB" and not "AC Charger" and thus will only pull in 500mah which is pretty slow. If you install battery monitor widget by 3C it will tell you the amperage coming in and if the phone sees your connection as USB or AC.
I discovered my 1amp apple USB brick does not charge higher than 500mah only my samsung one does that came with the phone.

yeah, but if I use the same USB port or the same AC plug I don't understand why 1 cable will charge fine, the other gives just enough to keep it at the same percentage all day?

The charger for my Tilt just broke and I need a new Charger. I have two chargers left over from my Blackberry days, The mini usb will fit my Tilt. Will it work ? Or for some reason will it short my battery/phone.
I remember reading a thread about non HTC chargers months ago, but for the life of me I can't find it.
Have a BB charger working just fine on myTrinity.
any miniusb connector which follow the miniusb std will work
be it connected any usb pc cable or any charger
if it don't follow the usb std as in use higher volts then 5
or don't use the same pins for power and groud as spc'd in the miniusb
std
it could break the device
but few would break that std as lawsuits would likely follow
I use my old Motorola V3xx charger or a mini USB from a PC.

I have actually gone down that route and got a "fat plug" with a USB socket on the top for travel, then all i need is one plug and assorted USB charging cables for things.

I decided to take a chance that trying the Motorola charger would not toast anything, I plugged it in, the amber light went on, but no charging icon and no charge.
I am currently using a mini USB cable and charging from the computer, but that requires leaving the computer on all nite, which as we are trying to be green, wastes more electricity than a simple charger.
Possibly the Motorola charger isn't pushing enough current to charge.
My blackberry charger is working fine, but my sprint isn't so good!
Whenever I plug my Desire in an AC outlet, it charges ridiculously slow. I check the battery status and it says "Charging (USB)" (not AC) and USB Debugging pops up. My wall adapter says it has an output of 1000ma. Is the chord bottle-necking the charging speed or is it the adapter? I am using the chord that came with my phone but I bought a new adapter to fit my countries outlets.
Same problem. I would like a resolution to this also.
There is allready a thread concerning this issue and it has the solution your looking for.

I have looked on the forums and it should seem like I should get regular AC charging on my Desire. I have a 1000mah charger and I am using the USB cable that came with my phone. I am wondering why I do not. I looked at my USB (fat side) pins and they are shortened. I have included an image of my charger.
if the adaptor says it supports iPhone etc then that is why the USB debugging symbol is coming up.
because that symbol is up it will only charge at 500mA max (the phone thinks it is in a PC, it doesn't wnat toburn out the USB port).
if it is a cheap adaptor, the voltage regulator may be limited to 100mA. thats what happened with me.
either way, in my eyes you have 3 choices.
1. buy a new adaptor
2. put a new voltage regulator in the adaptor (a friend did this for me)
3. use a converter so the adaptor you have will work in your wall.

O I didn't realize if it was branded to work with iPhone it would charge slowly. Thank you for your help. Next time I'll watch out for a "Works for the iPhoney."
Bump
I would like to know how it ended?
I have a same problem, the only difference is that i have stock HTC AC charger with separate USB cable (stock too). When plugged to AC it shows "charging(USB)". Tried different cables, same result. Tried two different AC adapters, but both were from NOKIA, same result...
This might help your slow charging issue
If the wall charger is causing your phone to charge in a USB state, the charge time will be very long compared to a normal AC charging state which I'm sure you are aware of. A cable called QuickCharge might help. It will enhance USB charging to AC charging. You can find it on Amazon by searching for 'QuickCharge'. It's the 2nd or 3rd item down.
I am considering buying this usb charging adapter cable to help speed up my charging rate at work where I don't have an AC adapter and my work computer's usb ports are conveniently placed. From what I have read, normal usb charging maxes out at 500ma, but can be increased if your usb port has more juice if you short the data wires, which will tell the phone to grab more power because it thinks it is plugged into an AC adapter.
I have found this adapter http://www.dealextreme.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
it is meant for a galaxy tab, but From what I see is that it has a switch that either allows data / slow charge or allows quick charging. I have purchased a few of these already because I'm assuming it will still work with my galaxy s2.
I'll let everyone know how it goes, but does anybody see a problem with this or think I'm going to fry my phone for any reason?
Thanks.
very interesting, heck it's only $3 bucks, might as well just buy it and find out
yes, charging via USB port sucks, it's too slow at 500 mAh
if that does the magic trick, by shorting it and making it believe it's an AC then it'll be nice, and it can pull around 1000 mAh off the USB port (depending on your computer mainboard)
Id be curious to see if this actually works but i see no fault in trying it

Only the Galaxy Tablets have this limitation (they cannot be charged at all via computer usb only via their "special" wall adapter) so the adapter won't do anything for a phone. The adapter works on the tablet because what the adapter is doing is shorting 2 pins on the USB cable to fool the TABLET into thinking it is on the AC adapter "specially made" for it.
As long as you plug the phone it into a self-powered usb port (ie: a hub with a power brick) you will get max current the phone allows. The adapter will make no difference on the phone because the phone CAN charge off the PC port while the tablet cannot. It won't hurt the phone but it won't help it either.

Thanks for the info on the galaxy tab, however I disagree with you in your opinion that an adapter that shorts the data wires will not help the phone to charge quicker.
It seems either the devices or android system itself limits charging to 500ma so it does not damage the computer, the phone itself knows that it is connected via usb, and will state "Charging: USB Plugged"
If you let the phone think it is connected to an AC adapter, it will allow the battery to accept whatever amperage you throw at it, and you will see that the system states "Charging: AC Plugged"
Obviously there are two modes of charging going on here.

Has anyone tried this yet?
I have found that using the Galaxy Tab chargers works the same way. They have a 2amp output vs the .5 amps that most blackberry chargers and USB use... It shortens the charge time significantly.

Charger considerations
Hi,
I need advise for the following:
Charger A (Li-polymer battery) output : 5V, 1A
Charger B (Li-polymer battery) output : 5V, 500mA
Device input: 5V, 750mAH (Li-ion / Li-polymer)
When using Charger A, some people comment that it will limit the current of 750mAH for the device and the device's battery should be fine since both the charger and device are at 5V. However, some people comment that this will shorten the battery life of the device since it will perform a 'quick charge' using 1A.
When using Charger B, some people comment that the device will draw more current than it can deliver and causes it to heat up and reduces the charger's life. However, some people comment that Charger B will extend the battery life of the device since it performs a 'slow charge'.
I also read that USB pins on the charger denotes if the charger is a PC or a dedicated charger. If it is a PC, the device will limit the drawing current. If it is a dedicated charger, the device will draw more current to charge itself.
I am confused as to who is right and which charger should i be using.
Can someone enlighten me ?
Thank you very much.
I bought an OEM Samsung wall charger that charges at 1 Ampere. I started to charge my Zerolemon battery with it yesterday at about 6pm and here it is today and it is only at about 80% charge rate. Something is not right. I contacted the seller and they told me that the charger is from Samsung and it charges at 1 Ampere. It is either the charger is a knock off or my Micro-usb cable that connects into the wall charger is not the right kind.
Are there different variations of micro-usb cables that will work better? Some that allow more current to flow over them than others? My cable says that it is 28awg/2C. I remember when I had a playstation 3 I had problems with syncing the device with my playstation 3 with the USB cables I had bought. After tons of research it was the USB cables that were the issue. They didn't allow enough current to work properly with the PS3. I'm starting to wonder if I'm having the same issue with the Samsung Wall Charger. Is the 28awg wire gauge too thin?

- charger is rated 1amp but usually puts out less depending on the quality and efficiency of it. You won't get the fastest charge with a 1amp psu. Get yourself a cheap 2amp and have plenty of headroom.
- also, if voltage in your wall outlet is low (rare) that would affect psu output.
- yes super thin usb cables can be part of the cause.
- of course, if the cable is meant for PC charging, it will be wired in such a way, to not exceed 450ma (or so) whereas a usb cable or charger that is meant and wired for fast charge, will provide...for me...1150ma (Search/Research my past posts for more detailed info)
- also, most kernels, slow down the charge rate as the batter gets closer to 100% charge.
- a bad battery or custom kernel with bad code, could both affect charging speed.
Hi,
I'm in deep sh*t, I lost a part of my luggage, where all the chargers for my phones and my laptop and the data cable for my SGS2...
In order to save on buying both a charger and a data cable (as on SGS2, they are separate), I'd like to ask, whether I could buy an
SGS4 charger ? Would it not do any harm to my batter on the long haul ? I know that the SGS4 charger is made of a USB data cable,
which is then plugged just in a socket connector...
Thanks!

my understanding is that so long as the output voltage is the same (5.0V) and the max output current on the charger is rated 0.7A (or above), you should be in good shape. I even occasionally use my ipad usb charger + usb data cable to charge my s2.
Yea most USB chargers should be fine. Heck, I'm using a $7 generic one I got from a local store because mine always break and it works fine.
I agree with Bigtonyman, using most microUSB charger is fine. Only output voltage must be 5V
I am charging daily my SII with: original charger 700mA (home), Nokia charger 950mA (parents) and occasionaly with china car lighter charger 1000mA, and from computer USB port.
I have my original battery 1,5 year old, and the battery time is similar to when it was new.
