The old tutorial worked for me for a day or two then this slow charging issue came back. However, I resolved the slow charging issue on my Galaxy SIII (GT-I9300) by changing the USB cable. It turns out the stock Samsung cable was faulty. It was not sending current to the device as it supposed to be. I used the HTC desire USB cable and this resolved my issue completely. Now, my device getting the charging current as it should get. On AC the charging current should be 1000ma and on USB it should send 460 to the device.
If not try some other cable with your charger and repeat the above process. When you get the 1000ma on max value, it means now your device is charging properly.
The procedure given below didn’t work for me either in long run. Please use the above updated tutorial for solving your charging issue.
I bought Samsung Galaxy S3 (GT-I9300) about a month ago, it is my first high end device. After using this device couple of weeks, I upgraded my phone to this official firmware update I9300XXEMD3.
After the new update, I encountered this strange problem in my phone. It was charging very slowly on the stock wall charger. I even tried USB charging via my laptop but it was not getting completely recharged.
For hours of searching on the internet, I finally found the fix. I am not sure if this fix will solve the slow charging problem on any other firmware but for me it worked though. For those of you who are having this problem, give this solution a try and let me know the results.
Note for Rooted users:
This fix has only been tested by me on the stock firmware I9300XXEMD3 and on stock android recovery. I don’t know if this fix will work on rooted devices as well but you can try it by wiping the cache in CWM/TW recoveries. But I would recommend asking some expert on XDA before taking any actions.
Things you need:
For Backup of your phone data, please read this:
If you want to backup your applications and apps data without root, you can use Helium backup app from Google Play.
After creating the app backup, copy all the important data from internal/external sd card via plugging your device with your computer and paste it to some place safe on your computer’s hard drive.
Note: You will not need this data, but just to be safe you should backup all of the important data.
Let me know, if this fix will resolve your issue of slow charging.
