The Apple Watch Ultra 4 launches September 18 for $799. Featuring the new S11 chip and upgraded health tracking, here is what you need to know about the device.

Apple opened pre-orders for the Watch Ultra 4 on September 9, with the device set for a wide release on September 18 at a starting price of $799 [1, 2]. The new flagship wearable aims to capture the high-end fitness market by integrating advanced health-sensing capabilities and Apple Intelligence features into a ruggedized, cellular-enabled chassis [1, 4].

## Upgraded Health and Processing
The Watch Ultra 4 is powered by the new S11 chip, which incorporates CPU, GPU, and Neural Engine components derived from the A20 Pro architecture [2]. This hardware upgrade supports a more frequent health-sensing system that monitors heart rate data every five seconds—a 60-fold increase in frequency compared to previous models [2]. Apple claims this system provides the most accurate heart rate sensing currently available in a wearable, supported by more power-efficient green LEDs and an increased electrode surface area for improved ECG readings [2, 3].

Battery performance remains a primary differentiator for the Ultra line. The new model offers up to 50 hours of battery life on a single charge, an increase from the 42 hours provided by the Watch Ultra 3 [3]. For users focused on endurance, the device includes a "Max Extended Workout" tracking mode that lasts up to 45 hours, with a 15-minute charge providing an additional 18 hours of usage [4].

## Intelligence and Connectivity
Apple has integrated "Audio Intelligence" features powered by Apple Intelligence, including a new Sound Recognition tool designed to alert users to environmental noises like doorbells [1, 2]. A "Live Rewind" function allows users to capture and transcribe the last 15 seconds of a conversation by double-clicking the Digital Crown [2]. Additionally, the watch supports Siri recaps, which can summarize meetings based on audio notes [2].

The device is available exclusively as a Cellular/GPS/Bluetooth model, allowing users to stream music and respond to calls or texts without a paired phone [1, 4]. While the base model is priced at $799, costs increase depending on the chosen band, such as the Titanium Milanese loop [1].

| Feature | Apple Watch Ultra 4 | Apple Watch Ultra 3 |
|---|---|---|
| Battery Life | Up to 50 hours | 42 hours |
| Processor | S11 | S10 (implied) |
| Heart Rate Frequency | Every 5 seconds | Lower frequency |

## What to watch
*   **Retail Availability:** Monitor inventory levels at third-party retail partners like Amazon, which is stocking the device alongside direct sales from Apple [1, 4].
*   **Carrier Adoption:** While pre-orders were not live on carrier websites on the initial announcement day, watch for the rollout of cellular plan activations as the September 18 launch date approaches [1].
*   **Real-World Accuracy:** Observe user reports regarding the "readiness" feature, which synthesizes activity, vitals, and sleep data to gauge physical recovery [2].

The Ultra 4 represents a refinement of Apple’s strategy to dominate the premium fitness wearable segment through hardware-level sensor improvements and proprietary AI features. Whether these additions provide a sufficient upgrade path for existing Ultra owners remains the primary question as the device enters the competitive landscape.
