After posting my Revision B iPhone X theory a reader suggested looking at manufacturing date information that could help test the theory. My failed iPhone X exchange replacement unit was manufactured in production week 3 (January) of 2018. yuya-310 who has the golden problem free iPhone X told me his was manufactured in production week 15 (April) 2018. His iPhone X is still trouble free and works great.
So we have an initial benchmark to work with: iPhone X production week 15 (April) 2018. If the Revision B iPhone X theory is correct, iPhone X units produced on or after this benchmark production week should be free of the iPhone X Suica problem.
If iPhone X Suica is your daily transit device I would greatly appreciate reader feedback on the following:
- production week
- factory code
- Suica problem unit/problem free unit
This could be a fun little research project.

**Week 15 of 2018 appears to be the Revision B iPhone X switchover production period
