Apple Watch Series 12 Adds Health Context, Keeps Familiar Design
The Apple Watch Series 12 looks a lot like the Series 11.
Its biggest changes are inside the watch, where new sensors can check some health signs more often.
It uses those readings, along with sleep and activity information, to give a Readiness score.
That score is meant to help explain whether your body may be ready for a busy day or could use a lighter one.
The Vitals app also compares your measurements with what is usual for you.
The reviewer says the Series 12 lasted longer than a Series 11 in their side-by-side test, even though Apple still rates everyday use at up to 24 hours.
It also charges faster and is designed to last longer during outdoor workouts.
A white ceramic version is available too.
The Series 12 looks much like the Series 11, with a familiar display and a stated 24-hour everyday battery rating.
Apple redesigned the watch’s health sensors, enabling more frequent background heart-rate and heart-rate variability readings.
New Readiness and Vitals features interpret sleep, activity, heart rate and HRV against personal patterns.
The reviewer measured about 30 hours of use for the Series 12, compared with about 26 hours for a Series 11 used alongside it.
The watch adds faster charging, longer outdoor-workout endurance and an optional white ceramic case; the review lists a starting price of ₹56,900.
