The fault is Phone is not charging, USB Power ( 5V, 10-20 mA) Battery Charging voltage 1.1 - 4.1V, current fluctuating.

Note : This is liquid damaged device

Observations & tests

  • TH voltage is 1.2V it seems OK
  • There is no BAT EN signal 0.6V

* Phone can be power on when given the BAT+ - to with external power supply

  • When plug the battery connector 0V at battery terminals. that's mean Battery Disable itself
  • When unplug the battery and can be get measurement 3.7V

Buddhika Mahesh this is going to be tough. There are no more schematics available since Sony does not repair any electrical components anymore.
