Apple Watch Ultra 4 Review: Series 12 Narrows Gap

Apple has unveiled the new Apple Watch Ultra 4, positioning it as a more advanced health‑tracking companion with a longer battery life than its predecessors. The latest model incorporates refined sensors for heart‑rate monitoring, blood‑oxygen measurement, and new metrics for stress and sleep, while its battery now supports up to 36 hours of continuous use under typical conditions. These upgrades aim to appeal to users who demand more precise data and fewer daily charges.

Despite the Ultra 4’s enhancements, analysts note that the mid‑tier Apple Watch Series 12 remains a practical choice for the majority of consumers. The Series 12 delivers reliable health tracking—including ECG, blood‑oxygen, and activity monitoring—at a lower price point and with a battery that comfortably lasts a full day. For most users, the incremental benefits of the Ultra 4 do not justify the higher cost, making the Series 12 a close enough alternative for everyday wear.
