Apple Watch Series 12 Hides Major Health Upgrades Underneath
The Apple Watch Series 12 looks very similar to recent Apple Watches.
Most of its important changes are inside the watch.
New sensors collect heart information more often and help provide detailed health insights.
The watch also adds a readiness score that changes during the day.
It needs at least seven days and seven nights of use before that score becomes available.
Battery life is rated at about one day, but the watch charges faster than before.
New software features make Siri quicker and add tools for recognizing and summarizing audio.
The reviewer thinks Series 11 owners may not need to upgrade, but older-watch users could find the new features useful.
The Series 12 introduces a redesigned sensor array shared with Apple Watch Ultra 4.
Its electrical heart sensor uses 32 electrodes, up from two on Series 11.
Background heart-rate readings occur every five seconds, providing more detailed health data.
Battery life remains rated at 24 hours, but charging is substantially faster.
The watch starts at Rs 56,900 in India, while ceramic models start at Rs 1,24,900.

Reasons to Upgrade
Reasons to Wait
Health tracking
Reasons to Upgrade
Owners of older Apple Watches may benefit from more frequent heart-rate readings, a redesigned sensor array, and a readiness score that updates throughout the day.
Reasons to Wait
Series 11 owners may see less reason to upgrade because the Series 12 retains a similar overall design and the same 24-hour everyday battery rating.
Battery and charging
Reasons to Upgrade
Faster charging, including up to 80 percent in about 30 minutes, makes the watch easier to use and can provide substantial use from short charging sessions.
Reasons to Wait
The official normal-use battery rating remains 24 hours, so the improvement is mainly charging speed rather than a higher stated everyday rating.
New software features
Reasons to Upgrade
Siri AI in beta is described as more responsive, while audio tools add faster Shazam, sound recognition, Live Rewind, and Siri Recap.
Reasons to Wait
Live Rewind and Siri Recap had not yet arrived in the review, limiting the features immediately available to users.
