Sony Z3 tablet charging problem

Hello.

I have a problem with charging circuit.

Firstly i had 5,0 V from the micro usb port (Then it was showing 1,35 Volts on battery + contact - which is low - Should be around 4,3 V?)

I removed the 6031 IC + 8620B0 and now i am getting only 0,7 volts from the micro usb.

Have anyone experienced something similar?

@kapuzta you removed or replaced the components? You do have a new battery correct?

Hei.

The battery is not new one but it is taking nicely 2.0 Amps of current when i tried to charge it with my powersupply.

The mentioned IC's i have tried to reball (Took from Z3 donor board replacements still the same).
