The Google Pixel Watch 4 is set to debut alongside the Pixel 10 series on August 20, 2025, according to the latest reports. While Google has not yet officially confirmed the details, a series of credible leaks and industry insiders have painted a clear picture of what to expect from Google’s fourth-generation smartwatch.
No Chipset Upgrade: Snapdragon W5 Gen 1 Returns
- Processor: Pixel Watch 4 will continue to use the Qualcomm Snapdragon W5 Gen 1 chipset—the same processor found in the Pixel Watch 2 and 3. This marks the third consecutive year for this platform, as a newer “sw6100” chip from Qualcomm is not expected in time for this launch.
- Why No Change?
- Google is reportedly preparing its own custom wearable processor for next year’s models.
- Availability and integration issues make a switch back to Samsung Exynos chips unlikely.
- Performance: Despite the lack of an upgrade, the W5 Gen 1 is still praised for responsive performance and strong battery optimization under Wear OS.
Sizing and Codenames
- Variants: Two sizes will be available:
- 45mm model: Codename “kenari” (FK23)
- 41mm model: Codename “meridian” (FME23)
- Design: Both versions will come with Wi-Fi and LTE connectivity, following the current industry standards for flagship smartwatches. Notably, these models adopt codenames inspired by Star Wars planets instead of the deities used in earlier generations.
Display and Build
- Type: 1.41-inch AMOLED color display
- Resolution: 456 x 456 pixels, 320 ppi
- Brightness: Up to 2000 nits, LTPO technology, always-on display

Battery and Charging Upgrades
| Model | Battery Capacity (Watch 3) | Battery Capacity (Watch 4) | % Increase |
|---|---|---|---|
| 41mm “meridian” | 307mAh | 327mAh | +7% |
| 45mm “kenari” | 420mAh | 459mAh | +9% |
- Faster charging is anticipated, though specific speed metrics are not yet available. These improvements are expected to extend operational time beyond previous models’ typical day-long life.
Other Key Features
- Connectivity: Wi-Fi 802.11a/b/g/n/ac/ax (2.4GHz & 5GHz), Bluetooth 5.3, NFC, GPS, and support for 4G LTE models
- Sensors: Heart rate, SpO2 (blood oxygen), temperature, accelerometer, gyroscope, altimeter, barometer, compass, electrical skin conductance (cEDA), and more
- Operating System: Wear OS 5.0

Expected Launch
The Pixel Watch 4 is slated for official unveiling at Google’s next product event, expected on August 20, 2025, alongside the Pixel 10 smartphone series, although Google has yet to provide a formal announcement or confirmation of the specifications.
