I researched before posting this. I'm a Nexus 4 user fixing my fiancÚ's sgs3. The phone started charging at 100mA a few days ago. So I flashed temasek and boeffla to ignore the detection problem. Now, however, the phone detects the AC charger as USB. I've tried a different battery and 2 other chargers.
Also, to get around this, I used boeffla's kernel settings app to increase the Amps when charging from usb to 1000mA and the charging current increased on the Galaxy Charging lite.

However, if i use the phone while charging, the battery percentage drops. I need a way to fix the USB/AC detection problem. I can't keep the 1000mA rate on USB.

Any help?

Try checking "ignore unstable charging power" and "disable charger margin detection ".
Set the USB current to 1000mA instead 475mA by default.
All that is done in Boeffla config.
If still the same, try with other USB cable.
If it keeps failing, I'd say the USB connector is damaged, common on these phones (and all other phones using microUSB)

Thanks for the reply. I've already tried all of that. It seems that when I plug the phone into the AC charger, sometimes the cable is detected as USB and it charges at 500mA (though set to 1000) and sometimes as AC. So what could the problem be here?
