First thing you should do in case that charging of battery is not possible is to run energy management calibration. Note that calibration only works with JBV-1. In Service jig it is not possible because of missing bottom connector I009.
Also check whether charging is only from time to time not possible or if charging does not work permanently. In case that faut appears from time to time only, especially check spring contacts of bottom connector I009 and battery connector X101 if bent, soiled or corroded. Also make sure that contact pads for bottom connector on PCB are clean. if necessary clean PCB with an appropriate amount of alcohol. Do not use any scratching or rubbing tools!

To ensure function of the phone run energy management calibration whenever a part has been changed in the charging circuit!

I009, X101
- check mechanical appearance of battery connector and bottom connector, change parts if bent, soiled or corroded.

F100
- check resistance of fuse. Must be 0Ω

V100
- check that V100 does not cause a short circuit to ground. Resistance of VCHAR-line to ground normally is ~ 2.8kΩ

D200
- due to the missing possibility of rewriting IMEI and Simlockdata after changing UEM D200 it is not useful to change this part at the moment.
