Since you have ruled out a parts problem it would point to the logic board. Firstly I would check the pins on the battery connector and make sure none are pushed into the plastic.

 I have seen tristar testers fail on the XR when tristar is perfectly fine. The tristar/hydra is next to the CPU on the XR so you would need to be certain it is faulty before replacing.

The most common cause for your symptoms on the XR would be faulty coils next to U3300. Replace these coils and it should solve the fake charging issue.
