Apple Watch Series 12 review: frustratingly inconsistent

Macworld tested the $399 Apple Watch Series 12, which adds upgraded health sensors, a Readiness app, Ceramic Shield 2 on aluminum models and a ceramic case option. Reviewers flagged inconsistent battery life and charging, occasional sluggishness, involuntary resets and delays to two flagship features.

• Starts at $399; ceramic version from $899
• New health sensors and Readiness app
• Aluminum models move to Ceramic Shield 2
• Two key features delayed; battery inconsistent
