@daantalks: The Apple Watch Series 12 looks familiar ⌚️ but there’s actually quite a bit that’s changed underneath. The biggest upgrade is the new Health Sensing System, with redesigned optical and electrical heart sensors and larger, more efficient green LEDs. It can now measure your heart rate every five seconds throughout the day, while HRV can be measured up to 24x more frequently — data that also powers Apple’s new Readiness score. There’s also the new S11 chip, more accurate step tracking, up to 24 hours of regular battery life and faster charging that can give you up to 12 hours of use from just 15 minutes on the charger. The aluminium models also get tougher Ceramic Shield 2 glass, while the display still reaches 2,000 nits. So while Series 12 might not look dramatically different, this year’s upgrades are really about what’s happening underneath. #AppleWatch #AppleWatchSeries12
