Is the Series 12 worth it over the Series 11?

If you want high-frequency HRV, hypertension notifications and the brighter LTPO3 screen, yes. Owners on older models call it a worthwhile upgrade; Series 11 owners gain less.

How long does the battery really last?

Apple rates it at 24 hours, or about 38 hours in Low Power Mode. Some owners report only a day of use with workouts and always-on display.

Does it work with Android phones?

No. The Series 12 requires an iPhone running iOS and pairs through watchOS.

The watch with a silicone band and a magnetic fast-charging cable. A USB-C power adapter is not included.

Is the 46mm case too big for small wrists?

It suits most wrists but is the larger of the two sizes. Try a 42mm if you have a narrow wrist or prefer a lighter watch.

The best new price was $308.99 at Rexi Resale as of November 7, 2026. Watch for drops around Black Friday and after new model launches.
