Problem:
1- Samsung S3 I747m, when connecting USB Cable, there is a delay of about 10-15 seconds before charging starts, same thing when disconnecting cable, delay of about 10-15 seconds until the charging light turns off (fake charging)
2- Battery can’t get to full charge and is having “spikes”.
USB port has been replaced and is known to be good.
Battery is OEM and brand new.
Now since all the schematics found on the internet are from the i9300 and the layout of the I747 is different, I worked on a known good I747 to locate the components.
Here’s the comparison that I’ve made so far:
I9300 Solution
Probable localisation on I747/T999
From what I understand, solution would be to change power IC U506, has anoyone tried this on this particular model? I'm not sure about all this because the battery is still able to charge, but not correctly...
I've seen this problems on more that just one i747, all with new usb port and new batteries and problem still persist.
