I9300 no power
 

I have a i9300 that no power no charging when I press power key it absorb 0.22A drp to 0 after stop pressing power botton
I have change If ic/power ic/osc400/osc500
After changing power ic it remain same drop to 0 after stop pressing power botton but absorbing 0.33A instead of 0.22

What can I do to fix this phone???

check the battery path first
if it's good ... software upgrade

Battery path is great no short on vat path
For software update no enter to downloadmode

Some one have told me to check vcc_1.8v_ap do you agree???

which VCC_1.8V_AP bro...?
try checking or rehot U500

I have change u500 still the same
Vcc_1.8v_ap is a output voltage of u500
