700ma or 1A give 1V and rise slowly to 3.7V until you will find exact location with heat.

Hey Wites,

Here are some findouts on the iPhone 3GS which is shorting:
Started testing by giving 1.5V and slowly rised up Voltage to 3.5V and maximum 1A.

1.5V consumes 0.35A
2.V consumes 0.7A
2.5V consumes 0.99A
Obviosuly I couldn't go higher than 2.5V as the power supply will reduce voltage because of current overload.

The phone does not power on obviously since vbat and gnd are shorting. Attachment 1 shows the location where at 2.5V I couldn't stand the heat on my finger.

Show please a photo zoomed of screw hole,i think there is short.


Look what happen in 3G phones http://img202.imageshack.us/img202/1...rtsolution.jpg
