Google Pixel Watch 4 Launches With Brighter Display, Faster Charging, and Gemini AI Integration

The much-anticipated Google Pixel Watch 4 has officially debuted as of August 20, 2025, continuing Google’s push into the premium smartwatch market. The new generation brings meaningful upgrades in performance, battery life, and software integration—without changing the familiar design of its predecessor. Announced alongside the budget-friendly Pixel Buds 2a, the Pixel Watch 4 aims to compete directly with Samsung’s Galaxy Watch8 series and Apple’s upcoming watch lineup.

Available in two sizes—41mm and 45mm—the Pixel Watch 4 features brighter displays that now reach up to 3,000 nits, significantly enhancing visibility under direct sunlight. Both sizes maintain the same 1.2-inch and 1.4-inch screens respectively, but users will immediately notice the brighter and more energy-efficient experience, especially during outdoor activities.

What are the key improvements in the Google Pixel Watch 4?

At the core of the Pixel Watch 4 lies Qualcomm’s new Snapdragon W5 Gen 2 chipset, a marked improvement over the previous W5 Gen 1. This enhanced SoC delivers faster processing speeds, improved GPS accuracy, and allows for more internal space to accommodate other features or better thermal design. According to Google’s hardware team, this upgrade is aimed at boosting responsiveness for everyday tasks and improving app interactions.

In terms of battery life, the Pixel Watch 4 gains small but significant improvements. The 41mm model is powered by a 327 mAh battery (up from 307 mAh), while the 45mm variant houses a 459 mAh battery (up from 420 mAh). Google claims these new batteries offer up to 30 hours and 40 hours of use respectively—even with Always-On Display (AOD) enabled.

Charging speeds have also been improved by 25%, thanks to the introduction of a redesigned “side charging” dock. Not only does this new orientation make it easier to use the watch as a nightstand alarm, but it also reflects a shift toward user-centric design in daily routines.

Gemini AI takes center stage in the Pixel Watch 4

One of the biggest software additions to the Pixel Watch 4 is Gemini AI integration. This new feature allows users to interact with Google’s AI assistant simply by raising their wrist. Gemini is embedded into a variety of native apps, offering real-time suggestions, reminders, and smart replies based on user behavior and context.

From fitness tracking to smart reminders and voice commands, the Gemini AI system is expected to make the Pixel Watch 4 not just smarter, but more intuitive than any of its predecessors. The watch supports over 40 fitness and health tracking modes, including ECG, blood oxygen (SpO2), HRV (heart rate variability), and respiratory rate tracking. These enhancements align with growing consumer demand for comprehensive wellness monitoring.

Google Pixel Watch 4 design, bands, and colors

While the design remains unchanged, Google has introduced new materials and color options to freshen up the look. The Active band now uses a more comfortable, soft-touch material and comes in Obsidian, Porcelain, and Moonstone. For those who prefer a sportier aesthetic, the Sport band is available in Indigo, Limoncello, and Iris.

Despite the design staying consistent, the refined materials and colors reflect Google’s subtle effort to elevate both comfort and personalization.
