Apple Watch Series 12 Brings Major Wellness and Sensor Upgrades
The Apple Watch Series 12 looks much like the model before it, but its sensors and chip have changed.
It can check some body signals more often without, according to Apple, using more battery.
A new Readiness score uses activity, sleep and other body information to estimate how prepared you may be for the day.
The reviewer found sleep tracking useful but said nap detection was not always reliable.
The watch can also use Apple Pay in India with supported Axis Bank credit cards.
Some planned listening and AI features are not available yet.
The reviewer says the watch offers many wellness tools, but people may have questions about privacy.
It costs ₹56,900 and up.
The Series 12 keeps last year’s appearance but adds a redesigned sensor array and a new S11 chip.
Heart-rate readings now arrive every five seconds, while HRV measurements are more frequent.
A new Readiness score combines recent activity, training load, vital signs and sleep data.
The reviewer reports up to about 36 hours of battery life in some everyday use, despite Apple’s claim of up to 24 hours.
The watch starts at ₹56,900; some Audio Intelligence features are not yet available, and the reviewer notes privacy concerns.
