GoKawiilApple Watch Series 12 review finds gains beyond Siri Recap and heart monitor
A week of hands-on use with the Apple Watch Series 12 highlights improvements in battery life and charging speed, attributed to the new S11 chip. The reviewer notes the watch now lasts through a full day and night of sleep tracking without needing a mid-day charge, and gains 12 hours of use from just 15 minutes of charging, per Apple. A new step-counter complication was also found exclusive to Series 12 despite step data being available on older models.
GoKawiil's interpretation of the reporting above, not reported fact.
Longer battery life and faster charging could make sleep tracking more practical for users who previously found juggling charges a barrier, potentially strengthening the Watch's competition with dedicated sleep trackers like WHOOP. The reviewer suggests Apple may be withholding software features like the step-counter complication from older watches to encourage upgrades, though this is presented as speculation rather than confirmed strategy.
- Series 12's S11 chip appears to significantly improve battery life and charging speed over Series 11.
- 15 minutes of charging now yields up to 12 hours of use, according to Apple.
- A new step-counter complication is exclusive to Series 12 despite step data existing on older Apple Watches.
Apple Watch Series 12 — This is the exact device the article rave about, with sleep tracking, improved heart rate monitoring, and faster charging that make daily wear far more seamless. If you're curious about ditching a separate fitness tracker like the WHOOP, this watch consolidates those features nicely.
