Where these two actually differ

  • We flag Microplastics from case degradation on the Mophie and not on the Xiaomi.
  • We flag Elastomer seal degradation (waterproof integrity loss) and Nickel leaching from metal casing or fasteners on the Xiaomi and not on the Mophie.
  • The Mophie is Plastic housing where the Xiaomi is Unspecified watch body, 5ATM, which is most of the difference in these two grades.
  • These two are level, close enough that price and fit should decide it rather than our grade.
