Update, charging problem solved as long as I use the Temasek kernel that enables "IGNORE UNSTABLE POWER DETECTION" and "Ignore unstable power". Not all USB cables work, which might indicate that the USB port might not be 100% OK.

Anyway thanks to this fix I can continue to charge and use the phone, now on Temasek V.38 with his kernel.

samsung galaxy s3 charging problem solution

hello, I have 2 S3 sch-i535 both have the problem in charging: when plug in to charge it shows the charging active. But the battery is not charged even the battery goes down from 73% to 61%. This weird attitude of charging is un-explain. I have to charge the battery outside the phone. Today when the battery going down to 54%... I plug in! It charged now going up to 56% in a minute after 2 hours it was fully charged. So the solution is to w charge the battery 100% outside the phone, than installed on the phone, wait for the battery near to 50% (in my case 54%)than plug in for charging it will charged normally. This success with certain condition : the phone show active charging but the battery is not charged.:good:

S3 charging issue

Hey guys i am facing a problem with my S3 when my battery drain completely and i try recharging my phone through the mains it does not charge, but it only charges on the laptop.

PS- if the phone is not drained the phone charges through the mains.

any help would be nice

thank you
[Galaxy S III Q&A, Help & Troubleshooting] kyleberry.graphics:
When you say drained do you mean dead? Some batteries lose charge to the point that trying to boot drains any charge they get. If this is the case an external charger will fix your issue. Ask at a local repair shop. I used to run into this daily, and instead of charging 20 bucks for the external charger, I would let my customers leave their battery for an hour, and charge it for free

SOLUTION!!!! SAMSUNG GALAXY USB Charger not Charging (or very but Wall charger is OK

[SIZE="5"]I am sure you have read many threads before arriving on this one. Well i had the same thing. on 5.0V 5V USB Charger i was getting no more than 466ma current. On the wall charger it instantly Jumped to 999ma.

How did i read my currents. well i downloaded a free app from Google play that displayed the current and voltages when charging.

Point: Some of you reading this may not have a straight wall charger with micro USB connector so may be wondering if this solution applies to you or not. I was almost at the verge of sending my S3 back to the seller i bought off ebay til i tried this solution. I will now be keeping my S3..

Well the solution for me was very easy. I used an IPA wipe and cleaned the USB charging port on the phone. Thats it!!!

Before i did that i removed the cover, battery to make sure i don't short out anything. i didnt use anything else, just shoved the corner of the wipe in there and kept twisting and feeding it until i was happy there was sufficient amount inserted into the port. You can also use a thin object like toothpick but make sure you have the wipe between the toothpick and the exposed connectors.

Thats it. My USB wall charger was now showing 999ma when i inserted the charge cable.I am going to watch it over the next few days. If the problem doesnt return i will defo keep this phone. Otherwise i may be forced to send it back to the seller. I dont want to do that because S3 is a good phone. Hope this will help some. [/SIZE]
[Galaxy S III Q&A, Help & Troubleshooting] pinmemo:
the phone reached its expiration date

this happened to me last week, bought the phone first day here in Thailand (sixth of May), almost like all the SGS3 in the world screwed up around the same time because they reached their designated expiration dates. You are lucky it happened fairly quickly, my phone is out of warranty now but apparently genuine Sony cable can charge the phone with absolutely no problem at all.

You can use an app in Play Store called galaxy current to see if the power goes it, it should be more than 900 when charging, my Sony cable gives it 1000.
[Galaxy S III Q&A, Help & Troubleshooting] VTrT:
Sorry for waking a bit old monster but, as I read this topic I see that whenever someone gets S3 to charge at 999-1000mA it's problem solved. And in my case from the beginning I was getting 1000mAh charge and still my phone charges from 5-100% in insanely 7hrs long charge :eek:

funny thing is that when I'm using phone while charging, lets say spotify + chrome I see battery level to stay still or even slowly drop, and of course all that while charging 999 mA. Am I doing something wrong?

Having the Same Problem

I have Galaxy S3 since January 2013 once its screen was cracked by some reasons so i got it repaired from a local samsung store.

Then it taking a very long time to charge from its original charger then i used my Galaxy Y charger. then it started to get charged correctly. After then now TODAY it got stuck last night i was having 54% of charging. But in the morning when I try to wake it up. it seems to be dead. I put it at charging as routine that it must be low charge. but after 8 hours it was still dead. Its not rooted and nothing was done with it. I connected it with my laptop it showed the Battery Icon Blinken up but when it is screen timeout it becomes dead again. Then after an hour i tried again and i got the RED LED Light(sign of charging) but when I ON it up it show the DOWNLOADING SCREEN and Please Do Not Turn Off the Target Warning.

then it again screen timeout and dead again.Still, Now i plugged it into USB port but it stuck at Samsung LOGO.

ANYONE HELP ?????? :crying:

#1: Make sure you battery is charged. You can buy a wall charger and 2nd battery for pretty cheap on Toabao or Ebay.

#2: For people still have charging issues. I never really figured out how to fix the problem so I found a way around the problem. I bought a wireless Qi charging dock and receiver on Taobao (you can get them anywhere though). It only charges at 466ma so I have to choose to keep the screen off while charging but it works all the time. I think my USB port on my phone is dirty or unreliable because it doesn't always charge with the wire.

#3: If your phone is corrupt or wiped even after you verified your battery is charged to 100% you may need to reflash. Pick a nice custom rom or if you only want stock, flash a stock rom. Check the wiki or forum to learn the steps to do this.

Same problem here, it is not the charger, it's a sofware related issue

I am having the same problem with my GT-i9300 S3.

Bought a new motherboard two months ago due to an irremediable IMEI wipeout . Everything was good with my phone till last week when I started to notice that my battery charging period is starting to get extremely slow. I plugged it in a 10:00 PM with a 5% quantity of juice left, the next day at 11:00 AM, the battery was 90% charged. At 1:30 PM my battery was fully charged. That's over 14 hours of charging time.

I went and googled the issue and found some partially useful tips. Some said to wipe cache partition, didn't work for me. Some said to turn on battery dump from dialer menu: *#9900# didn't really work. And then I tried one method that somehow worked: Turn off your phone, remove battery, sim and SD card, wait a few seconds, insert them back. Turn on your phone and charging time will get back to normal, at least for that one particular charge and only if stop using it while charging.

I've noticed that if used it this particular charging period the phone starts to slow charge again. Example: yesterday I plugged in my phone at 9:00 PM with the "Turn off your phone, remove battery, sim and SD card" method. The battery was at 4%, in approximately one and a half hour, maby less, my battery went from 4% to 50%. I went and checked my email on it, opened Megapolis (online game) for 5/10 minutes max, closed the game, cleared RAM, killed all tasks and running apps with Clean Master and left it further to charge. Woke up today at 9:00 AM and the phone was not yet fully charged. A bit strange don't you think? So my personal guess is that it is somehow software related not at all hardware related since I am using the original charger, also tried my other original Motorola charger and nothing changed. Also want to mention that the problem started a few weeks after I flashed Cyanogen mod 11. Recovered back to stock ROM, worked normal for a couple of days and the the problem reoccurred .

If there is someone out there who has figured out how to solve this slow charging issue on Samsung Galaxy S3 GI-i9300 please let us know.

Thank you! :o

hi guys,

im experiencing the same issue here...

but! it looks like the issue only comes up when im using a non samsung usb cable! i have ordered some cables from ebay and they seems to be not good to charge galaxy s3 as sometimes they charge sometimes they not... weird! cause, when i plug my phone in to the usb port in pc, the phone is still visible in pc while its not charged. strange? very.... but this doesnt happen with genuine samsung usb cable... dont know, maybe they have changed pin layout???

also, the other cable that WORKS with SGS3 is my partners BlackBerry usb cable.. no issue with this one too...

i have contacted service too, but i dont really want to send my phone back...

all the best guys!

Im having the same problem on my sgs3 I'm using the omega rom, is this the same rom everyone with this issue is using?
[Galaxy S III Q&A, Help & Troubleshooting] Jack4L:
Have had this happen twice now. First time it happened it was hovering at around 40% charge no matter what charger I used. I turned off the phone, let it charge, took the battery out for 15 mins and then turned it on. This worked, and the phone survived through a weekend of very light use. So it went 2 days on a single charge and didn't even drain all the way to 0% so I was impressed :)

So I charged it up to full over the night, and the next day it was in fairly active use after which it drained to 0% as I forgot to set it charging. The next day I managed to only get it up to 50% before leaving for work in the morning. Took about an hour, at work I had it plugged in the USB of my computer for the whole day. At work it didn't gain any charge but then again I was putting it through the ringer in terms of consumption.

I didn't let the phone run down to 0% that night, but through the whole night the phone didn't charge at all. A battery monitor graph just shows a "gentle" wave through the night, after waking up I noticed that I had a few too many apps running in the background so I swiped them away, 30 mins later it still hadn't charged. So then I went to the task manager and cleared the memory (Which was quite full at the time) and then suddenly it started charging.

So I'm completely baffled by this, I'm just posting my experiences with this issue in case it sheds light on anyone. I'm not convinced this is a hardware problem yet, but possibly a software related one.

As a side note, Wifi doesn't effect this in the least. I never have it on, get all my data through 3G.

charging problem

my i9300 is working fine, ive had it for 3 weeks now.

try return for warranty if not just call up the company or send the phone back to them to have them check it out. if you cant do that then just bring the phone to the store where you bought it from and have them send it or try to fix the problem on the spot.

After seaching all over the net i found people having similar problems to myself.

Had my S3 for just over a week and on the third day the Official charger stopped working. Got another micro usb cable and it worked for a few days and the same thing.

Tried the rebooting method and it works with the unofficial micro usb cable but the official supplied cable is dead, completely. Wont even recognise on my pc or anything.

Im NOT running modified firmware yet so the plot thickens as to what could be causing these issues. As it stands im getting a replacement sent out from my phone carrier on Monday.

so I have an issue where it charges.. but only at a dribble. I can imagine it is like pushing water up hill and that some process was using the processor at full speed (all night). Overnight wall mount charge went from 8% to 13%. But after a reboot and it immediately starts charging much better. God knows what this is doing to the hardware.

Samsung make terrible software. Lucky my alarm went off.

with wallsocket - sometimes it will charge on the 1st attempt, but if i off the power and on it back, it wont charge most of the time.

and if i plug into the laptop, it can charge no matter how many time i unplug and plug it back

i have been playing around with the seetings and i try turn on power saving and it solved the problem. Guess this is the software bugsssss from samsung...

hope this will help on your phone as well

[Galaxy S III Q&A, Help & Troubleshooting] ImraanK:
My normal Samsung cable and charger work fine... but I got a slightly longer generic cable which charges my s3 on the pc but will not charge when connected to the Samsung charger. So i paired the cable to a apple iphone charger(same output spec as the Samsung 5v @ 1.0a) and that works a treat.

So imho.. the Samsung wallcharger is crappy

How exactly did you update using Kies?
[Galaxy S III Q&A, Help & Troubleshooting] prabhjots:
Seems to be a software problem

The problem does not seem to be with the charger as much as it looks like a software bug.

I tried using Darken's TRUST Event Logger. It logged "Power plugged in" when I plug in. The phone stops charging after a few seconds. However, it logs "power disconnected" only after I actually remove the power source, (by either switching off or removing the cable).

So I think it is a software issue. Another reason is that the wall charger works perfectly fine with older phones. Haven't had a chance to get hands on another S3 yet :)

[Galaxy S III Q&A, Help & Troubleshooting] forsakened:
Running CheckROM V4 with Siyah Kernel 1.4 Stable.

I had a Belkin USB extender cable attached to the wallsocket charger and the samsung cable connected to it since the socket is a bit far from my bed.

The charge is very, very slow. I mean, painfully slow! But facing no other issues. At first I thought it may be the ROM. But reading this thread, I'm beginning to think otherwise.

Going to the check the following things and report back:

1) Use only the original cable with the wallsocket. Will see if it charges quicker

2) Use the extender + original with my iPhone charger and see if that makes a difference.

For those saying they fixed it via update from Kies, can you please elaborate? Which update? What version etc?

Thanks!

weird issue here, my sgs1 charger works, my son's BlackBerry charger works, but when I use my S3 cable and wall charger it says usb charging and is very slow, even with siyah kernel charging tweaks
[Galaxy S III Q&A, Help & Troubleshooting] mariachi84:
I had some issues as well and this is what I figured out:

There are three szenarios:

1. Charging from wall socket

2. Charging from USB 2 device

3. Charging from USB 3 device

Wall socket should charge with 1000mAh; USB 2 with 500mAh and USB 3 with 900mAh. So wall socket should charge the fastest.

But these are only the maximun outlet. I believe that plugging the S3 into an USB 3 device, you also get only 500mAh because Samsung stock rom does not support charging from USB 3, so it behaves like charging from USB 2.

But the other problem is that your cable must also support the outlet. If you buy a cable which can only handle 300mAh then your S3 charges very slow, no matter what.

On most cheaper usb cables you won't get any information on that. They just don't tell you if the cable can handle 1000mAh. Only better cables have specs for that. If I'm looking for such a cable in most cases you won't get any information about that. If you buy it, it may work or may not work.

-> Samsung charger should just work well in any given szenario

-> Others could work well, for example amazon basics cable which costs some $$$ more than others but this cable has specs to work up to 1,5A (1500mAh for charging)

Same goes with third party wall socket adapters; they should at least be able to handle 1A.

(sorry for bad english)
[Galaxy S III Q&A, Help & Troubleshooting] alextheguy:
Try power off + power on it back. Or do a factory reset. Or is it your charger problem?
[Galaxy S III Q&A, Help & Troubleshooting] prabhjots:
I'm unable to pinpoint the exact cause.

Sometimes it charges with my own Wall Charger while most of the times it stops just after a few seconds of plugging in. However, the screen lights up when I unplug the charger or switch off the charger. This means that the power source was being detected all along by the phone, just not charging.

Also, it will charge sometimes with the S2 charger (rated 700 mA) and most of the times even that will not work.

This leads me to believe it is a software issue.

I believe Factory reset will only hide the problem temporarily and not a permanent fix.. Maybe somebody could read through the syslogs and comment? :)

[Galaxy S III Q&A, Help & Troubleshooting] corrsea:
I had this exact problem. Turned out it was a combination of both the charger and the usb cable. Replaced them and have not had any issues since. Replacing only the charger or the cable made no difference.
[Galaxy S III Q&A, Help & Troubleshooting] prabhjots:
Some more Observations: Others please try this out and confirm your results here..

Plug the wall charger, Charging stops after about 10-20 seconds, Slightly twist the cable, charging starts, and again stops after 10 seconds.

Again twist the cable a bit, and hold it there, charging starts, and again stops.

This seems like a cable issue from the above.

However, plug the same cable in a Laptop USB port, it keeps charging, no matter how much twists the cable is given.

Keep it plugged in the USB for about 5 minutes or around 4-5% charge, Then remove the cable and use the same cable with the Wall Charger.

Voila! The same cable that was suspect earlier keeps charging until 100%, no matter how the cable is kept.

Now, it doesn't seem like a charger/cable issue, does it? STRANGE!!! :eek:
[Galaxy S III Q&A, Help & Troubleshooting] corrsea:
BTW the shop I purchased my phone from replaced both the charger and cable under warranty. I demonstrated all the various working/non working combinations to them. They phoned Samsung who instructed them to issue a replacement.

I have not had any further problems, but I no longer use them in combination. I use a good quality 1.5 meter cable with the wall charger and use the Samsung cable only for usb connections to my computer.
