Apple Watch Series 12 review: the upgrade worth making?

## Overview The Apple Watch Series 12 introduces several internal upgrades while maintaining its familiar design. The key enhancements include the new S11 chip and an updated Health Sensing System, which aim to improve health and fitness tracking capabilities.

## Key Features The Series 12 is powered by the S11 chip, featuring a 64-bit dual-core processor and a four-core Neural Engine. It offers 64GB of storage and supports advanced intelligence features. The watch retains its Always-On Retina display with a peak brightness of 2,000 nits, making it suitable for outdoor use.

The Health Sensing System now includes a second-generation electrical heart sensor, an always-on optical heart sensor, blood oxygen sensing, and a temperature sensor. These features enhance the watch's ability to monitor health metrics, although availability may vary by region.

## Performance The Series 12 focuses on improving background functionality rather than altering its appearance. The new sensing system and S11 chip allow for more frequent heart rate and HRV sampling, enhancing fitness and wellness tracking. The watch's battery life remains at up to 24 hours of normal use, with fast charging providing up to 12 hours of use from a 15-minute charge.

## Who Should Upgrade? The Series 12 is a compelling upgrade for iPhone users with a Series 8 or older Apple Watch, offering significant improvements in sensing hardware and battery life. However, Series 11 owners may find fewer reasons to upgrade, as the overall experience remains largely unchanged.

## Conclusion The Apple Watch Series 12 is a solid upgrade for those with older models, thanks to its internal enhancements and improved charging capabilities. For recent model owners, the decision to upgrade depends on the value of the new features relative to their current device.
