Hi ...
Yesterday away from home I didn't have my original S3 charger with me so I tried to charge it using a generic charger and it didn't work, so I tried with another one and that didn't work too. I tried with three different generic chargers and all didn't work so finally I had to manage an original HTC charger and that one worked so my question is whether not a single generic charger will work with S3 and only the original one will work or is there something can be done in this regard as I can't always have my original charger with me.
Thanks.
S1/S2/BlackBerry all work for me
Some generic chargers work. They do mostly say on the package so you will want to check. I have galaxy s, desire, optimus, galaxy note, xperia arc s chargers that all work on s3. Korean galaxy note don't work though..

I bought an portable charger from abker that works well, got another for charging in the car and that works fine too. But I am rooted and on a custom rom though. I think samsung has something built in to not let generic chargers work.
My gal tab don't charge on generic or through usb. Has to be from an ac source.

I use a generic charger from HAMA. It works just perfect.
It's depending on current potential
The original charger has output current of 1A, some generic charger doesn't have that much potential, so I guess that's why not working.
Some of the bad quality may charge your battery, but also will interferes your touch screen operation which means your screen would unresponsive or go crazy when you charge it...

Yes, that did happen. Screen went unresponsive for quite some time.. Anyways I guess you are right.. It should be because of not appropriate current..

For the screen going haywire/unresponsive (Touchscreen Electromagnetic Interference), the problem is with your charger. Low quality chargers have a lot of 'noise' and may not provide a stable current as well. Get rid of such chargers...
As for the charging itself, the quality of the USB cable has an effect as well. Low quality cables may not even be able to allow 1A of charge.
Install "Battery Monitor Widget" to monitor the charging process.
If you just want to know the charge received by the phone, just install "CurrentWidget"

It will affect the life of the battery or there is no difference between chargers?
Thank you!
Yes
But,
SGS2 charger rated @ 5V/0.7A
SGS3 charger rated @ 5V/1A
Meaning: Using the SGS2 charger with the SGS3 phone will charge at only 70% the rate > ie take longer..........
Edit: No, it will not affect the life of your battery, could even possibly extend it as the battery is affected by less heat generated.
Then I guess the same applies to using the charger of the SGS for the S III. That charger is also 0.7A.
(I'll be using it since it has a longer cord. The charger of the S III doesn't reach from the outlet to my night stand...
Just buy a longer USB cable that's all i did.
if anyone is ever stuck without their original charger i can confirm i have used my wifes old blackberry charger. my sons galaxy ace charger. and an iphone charger with micro usb cable plugged into it. all worked fine on both my s2 and now my s3. as long as it is micro usb and not crazy high amperage it should be fine.
So as long as amperage isn't too much over 1A, all is ok?

Apparently the SGS3 limits the charge rate to 1A max on AC charge.
SiyahKernel plus the extweaks app have an option to increase this limit.
Personally, I have never tried it, and don't particularly wish to.
So to answer your question, theoretically, the phone will limit the charge rate to 1A whether you're using a higher capacity charger or not. Most likely to protect the battery and charging circuit from damage.

I'm using the S1's one at the moment...same thing really, as the above poster said, might charge slower though.

This is wrong mate.
You CAN use the charger from the S2 even though it is rated 0.7A. It actually is capable of putting out more than that. You can use current widget to check this.
I have checked and on the S2 charger, the S3 draws 0.999A same as on S3 charger..
However, using it for prolonged periods will probably result in a damaged charger. I would use it only in emergency.

I never said you couldn't, just said it would take longer
My official SGS2 charger IS rated at 0.7 A (yours may be different), confirmed but not tested with a ammeter, which would be much much more accurate than any widget.
Can't borrow one from work unfortunately...

Apologies... Just read ur post again.
It won't take longer either as the S3 draws what it needs. The S2 charger will give out 1A although not sure how long it will last longterm.
I've used "current widget" and on quite a few phones now and it's pretty good. It might not be 100% accurate but it's not that far out. On my S2 the different charge modes in Siyah kernel could easily be seen in current widget. Same with my S3... Current widget reads same whether I use my new or old charger..

Is that safe? From what I get from http://en.wikipedia.org/wiki/Usb#Power , no more than 0,5A is expected to travel through a USB cable.
Is the cable we get from Samsung perhaps made for the 1A? It is quite a bit thicker than most other USB cables I have...

Yes , the device will only take what it needs.....no matter what the output amps are.
Devices are built to limits their input current.
Sometimes I use data cable from old Samsung to transfer data or charge.Still no problem.:good:
I've only ever used my S1 charger or my old S2 and now S3. Every so often I use a Nokia cable paired with my galaxy tab 10.1 charger and haven't had any problems.
Sent from my GT-I9300 using xda premium
Most devices won't draw more than they need. I've used anything from a 0.3A charger through to a 2A charger... in my experience the S3 doesn't charge any faster on the 2A, but it definitely charged slower on the 0.3A (perhaps because it was limited to a max output, I may have to see what this "current widget" says.
Here's the catch though, it will charge faster on a higher amperage during heavy use, than it would on a lower amperage.

Recently I traded my galaxy nexus for a galaxy tab 10.1. But whenever I plug it into a computer or an outlet there's a red x on the battery... it charges reallllly slow. I left it to charge for nine hours from an outlet while turned off, and it went from 5% to 55%. WOW. That's really slow. So I thought that the problem is the cable so I bought a new cable that came with a car adapter. And it worked like a charm in the car. However when I traded I kept the 3 pronged galaxy nexus charger. So anyways I arrived home happy, but I wanted to test it in the computer... Red x again. I tried the wall outlet, again with the x. I tried the wall outlet with 110v and 220v still red x. Then I looked at both outputs on the wall charger and car charger both had the same output which is 5volts and 1A. Then I looked at the input and the car charger was 12-24VDC and the wall outlet was 100-240v and 50Hz and 0.15A. I need help please.
I have 3.2 honeycomb and P7500.
I think that this is an internal issue software wise.
If you need anymore information don't hesitate to ask.
Thanks in advance

On stock settings u wont be able to charge the device connected to ur computer and u will get the Red X on the battery icon! Therez a small tweak to activate that feature to activate charge on pc connect but u will loose the mtp connection. As far as this issue... Seems to be a battery proble. Still try to flash and get to stock to confirm.

What do you mean by loosing mtp? Also I'm a bit noobish at this because I just switched from ios. So can you dumb Down what you said a little. And what do you mean by "still try to flash and to get stock to confirm."

I get that if I try use galaxy nexus charger, however if I charge my galaxy nexus with the tab 10.1 charger I have no problems, make sure your using the correct charger, and for the slow charging I have a USB extension cable if I use that it can take up to 12 hours for a full charge
By charger do you mean cable or outlet?
Sent from my GT-P7500 using xda app-developers app
simplest answer is that the red X means that you're not supplying enough voltage to your tablet. You need 2A (A = Amps), computer USB ports generally do 500mA (1/4 of what you need). Phones usually need less. So the reason your tablet won't charge off the phone charger is because it doesn't supply enough voltage; the phone does fine on the tablet charger because it's just oversupplied (don't worry, your phone won't be damaged by this!)
So what you need is:
1) an original charger for this particular tablet (the cable probably isn't the issue, but I've seen cables that can't transmit the full voltage. The nook color is a good example of this)
2) a 2A charger - can't promise any particular ones work though...
3) (and this is the one you should do): You're on XDA. This is a place for folks who root and install custom ROMs on their devices. Most of the ROMs have USB charging built-in (in the Kernel; don't worry about what that means). Install a custom ROM (I'd suggest AOKP). Problem solved, plus you've increased both performance and functionality of your device exponentially. If you're not willing to do this, XDA probably isn't the place for you anyways.

I found a solution to a problem that was really vexxxxing me. One of my chargers was working and the other (longer lead) all of a sudden started showing the red cross. Ahhh. The solution (http://www.androidtablets.net/forum...galaxy-tab-10-1-not-charging-brand-new-3.html) was to blow very hard on the 30 pins of the charger and hey presto - started charging again without the red cross.
There are solutions to this problem with quite a few custom ROMs. Task's ICS for example has this patched. I am quite certain there are others.
Okay, this is a weird one. When charging my phone, almost every single time, it will charge up to about 76-83%, and then stop. However, if I unplug it and then plug it back in it will resume charging like normal up to 100%. I mean this is bizarre...is it a battery calibration issue, perhaps?
Edit: Happens on any/every ROM I use.

You mean the usb box from ur galaxy s2.... If so each box may have a different output for each phone..... For instance when i use my daughters charger it takes 5 times longer to charge my og than the og charger so that may be ur problem.
Via LG OG running Rootbox 4.2.2
Had the same thing too and as described in the post above it is in fact due to the output. Just compared my old but still kicking s2 and my og charger and the og charger has a much greater output.
Yeah lgog charger is 5v 1.2a. It's very nice. We also gotta qualcomm technology called quick charge or something like that that enables the battery to charge substantially faster without damaging itself. It's a logic chip in the phone and improved battery chemistry from LG. Asian manufacturers have a huge portfolio of products and are weirdly driven to diversify in all directions. LG has their own chemical company, and that's who makes our pimp batteries. I stuck with HTC for 7 years, but if LG flagship phones continue to have decent development then I'll probably stick with LG for a while. It's cool that they manufactured the entire phone from scratch except the SoC, no other company can really say that besides Samsung. And they're both Korean companies. Btw, south Korea is a great place to vacation.

It looks as though I need to pay attention a bit more. I was using the LG wall charger, however, I wasn't using the right cable. I was using my Samsung cable. The Samsung cable is longer and reaches to where I can charge and play with the phone at night. I'll try the cable it actually came with and see if it continues to pull the same trick. The LG cable is definitely thicker.
Sent from my LG-E970 using xda app-developers app
I totally agree with you on the length of the cable and is why I was also using the s2 charger as well. If you need the extra length you can probably get by using an s3 charger. I steal my girlfriend's s3 charger from time to time just because I want a little more mobility than two feet and it charges the phone just fine with very similar output ratings....... 1.0 amps compared to 1.2 amps of the og charger.
I've had something similar happen recently. The phone will either charge extremely fast or extremely slow. I usually charge my phone at about 30% and sometimes it will charge fully in about 90 minutes and others it will take up to 8 hours, with the slowest part being in that 73-87% range you describe. I always use the LG charger and cable because its the only one that I have. I'm running code fire's CFX ROM if that helps anyone out.

That's some weird stuff. I'm getting good performance right now using the stock cable with a belkin 1A cigarette lighter to USB adapter. But last week I grabbed a cheapo Chinese retractable cable that was in my wife's car and plugged it into the built in USB port in the car (don't know what it's rated output is) and the battery drained VERY fast... Roughly one percent every minute or 2. Freaked me out... Certainly appears to me this phone is temperamental about cables...

yeah had the same probably with a car charger with my og and to think about it my s2 as well, I travel a lot for my job and constantly use gps while traveling and I've found that a lot of those cheapo car chargers you pick up from gas stations may charge the phones while inactive don't really charge them very well while in use. I could watch my battery percent fall while charger on both my s2 and og while using navigation, ended up finding a high output charger at a truck stop with a cord the size of a cb radio lol and havent haven't had any issue with it since. This is with stock and custom rom, even reverted back to stock a couple times to make sure that it wasn't the custom firmware that was causing the issue. Guess the makers of cheap chargers haven't caught up with the big batteries todays smart phones pack, should of hold on to my bag phone charger a little longer lol!!

That's on thing i do miss about having a removable battery though, is the fact that a large part of my job is in very dusty dirty environments ....i.e. steel, aluminum mills and other high temp dusty and dirty as hell places is that i could remove my battery and feel safe while using a little contact cleaner. Now og days i play it safe with air. But either way i don't think that has anything to do with the use of cheap chargers lol. Best bet would be to stick with oem or pay the extra price tag for those high out put chargers that att offer.

to me it seems a hardware problem... If with different romcameras still fail... it could be a hardware problem in the main board.
Get a custom kernel and look for this setting in the kernel config: "ignore unstable ... ".
That should improve the charge rate significantly in your case.

Have you used different charging cable? Buy some original nokia cable CA-101D. Please buy original one.
Samsung charging cables are crap. This is cable issue.
Not necessarily a cable issue, he said he tried different charges as well. Also, your stock charges are generally 1.0A (Samsung), Nokia is 1.2 if i'm not mistaken. I dont think u can configure your phone to receive more charge from a wall charger than its output. You could try altering your USB port, but im sure there's a hardware cap on the port itself. Just send the phone in for repair.

How do tell what amps it charges at? All I can find is what the voltage, using 3rd party apps from the play store of course. My phone charges incredibly slow. Especially if I'm using it during the charge cycle. Hours can go by and it just sits there at 5%.

The Fast Charge mode on the KT kernel has no impact on AC charge rate, it only affects USB charge rate:
Normally, when you connect to a PC, you get about a 500ma charge rate and the ability to pass data along. When 'Fast Charge' is set, you lose the ability to transfer data, but the 500ma restriction goes away. In practical terms, it means that you should see between 700ma and 900ma as a result.
w/respect to the OP, my experience is weird. When the device was new, I got around 1800ma on stock charger and cable; now, same setup gets me 900-1200 if lucky (even with new battery). When I tried the stock charger with a different (newer) cable, I get around 1600. It's strange that a cable's ability to carry a charge would degrade so quickly (if that's in fact what's happening).
I have no proof, but absolutely believe that kernel can influence max charge rate, because in the past, I've observed max charge rate drop with the release of a new kernel version, then go up again with another release.
Samsung did slow the charging rate in one of the OTAs. People had been complaining about the phones getting too hot.

What are you using to measure that? Qi isn't capable of charging at 1.9a
The galaxy charging current app..
So you've noticed that sometimes your phone seems to take forever to charge, and other times it seems to charge fine? Let me share some ideas that I've learned through lots of research on this exact subject last year...
I have used the galaxy charging app myself. In my opinion, CurrentWidget is better...looks cooler too. Ha.
So other than software related issues, you need to remember that the speed in which your phone charges is highly dependent on the hardware of 3 things:
1) Power Outlet (including power strips, extension cords, USB extenders, etc.)
2) Power Adapter (I highly recommend Anker's products!!!)
3) MicroUSB Charger Cable (if not using the factory Samsung cable or an Anker one, be sure that it's an 11-pin microUSB, and NOT a 5-pin...they look the same!)
Power Outlets - I know for me, if I use the outlet in my livingroom, it takes SO much longer for my phone to charge than it does in my bedroom. Just try this test! Grab that CurrentWidget app from above and try out some different outlets throughout your house, just to see whether or not the voltage varies. I bet you'll see that this is true!
Power Adapter - You should be using either the factory Samsung charger or a reputable 3rd party charger with the equivalent specifications (5V & 2.1A). However, I actually prefer my Anker charger over my Samsung one! If you're finding that you can't get a good charge, try swapping out your adapter with another one.
MicroUSB Charger Cable - As stated with the power adapter, you should also try to stick with your factory cable if possible. HOWEVER, I have found that to daily connecting and disconnecting of the cable with your phone, they probably receive the most wear and tear of anything else, and therefore may need replacement after some time. Again here, I find that using either my Anker cable or Samsung cable will give me the best charge. This is determined by both the CurrentWidget app and the amount of time it actually takes to get a full charge! Keep in mind that using USB extender cables can drastically lower the voltage to your phone - thus causing a very slow charge.
So basically, I know if I need to charge my phone as quickly as possible, I know I should clear my RAM and recent apps, put my phone on airplain mode, and using my Anker charger, I plug-in at the outlet near my closet door! I figured this all out by using these same ideas I just shared with you! Hope this is helpful!
If you can tell the difference between outlets, you need to call an electrician. Not kidding.

I doubt that's entirely true. I mean, think of if they're on different circuits, that kind of thing can vary...also, depending on what you have plugged into your outlets can cause lower outputs I'd assume. I'd bet if you used the app I referred to and ran a test at each of your outlets, and reported back here (being honest of course), that you'd see some differences. Anyways, that was far from the point of the post. But thanks for the insight!

The Samsung power supply is rated for 100 to 240 V @ 0.5 A input. It may be that the power supply is kind of crappy, and varies its output under small variations in input voltage, which is why you see what you see. It really shouldn't...but it wouldn't shock me if it did given that its made for $2 in China. Makes you wonder what would happen if you plugged it into a 240V source. When my wife went to Malaysia last summer to visit her folks, I just put a US to British transformer-less adapter on her Motorola brick and it worked OK plugged into 240V. Maybe the Samsung ones are crappier?
I squared R losses should be reasonably low in household wiring. NEC is 5% drop max at the outlet. And that is like the outlet the farthest from your mains under full rated load. Assuming you live somewhere typical, your voltage at the panel will be 120V+; a lot of time its a few volts over 120. If you have an outlet that is not tripping a breaker go below 100V, you have a problem somewhere. A 20% drop is not normal. Have you put a meter on the outlets with low charge rates?
My friend's OEM s4 charger charges at 1900 ma while my OEM charger only charges at max 1200... Weird how that happens but somehow the cable just stops charging as fast.
