Google’s Pixel Watch 4 has leaked in high-resolution images ahead of its official unveiling on August 20, confirming its final design, multiple color options, band styles, and a notable change in the charging system. The leaks, posted by well-known tipster Bedros Pamboukian, reveal the smartwatch in Black, Silver, Gold, and Moonstone case colors, paired with a variety of Active Sport Band options.
The Pixel Watch 4 maintains the circular display design characteristic of the Pixel Watch lineup but features a small yet practical tweak: the pogo pin charging setup has moved from the watch’s underside to its side. This change is expected to facilitate faster repairs and supports up to 25% faster charging speeds compared to the previous generation.
Two size options will again be available—41mm and 45mm—mirroring the Pixel Watch 3 released in 2024. The new model is reported to be slightly thicker by about 2mm, likely to accommodate a larger battery improving battery life. Display sizes remain the same at 1.2 inches (41mm) and 1.4 inches (45mm), but peak brightness is significantly improved, with the Pixel Watch 4 supporting up to 3000 nits, compared to 2000 nits on the Pixel Watch 3. This enhancement will improve visibility in bright outdoor conditions even though bezels remain relatively thick.
Under the hood, the Pixel Watch 4 will continue using the Qualcomm Snapdragon W5+ Gen 1 chipset but now pairs with a new M55 co-processor designed to boost power efficiency and handle AI-related tasks more effectively—potentially including deeper integration of Google’s Gemini AI features.
Health and sensor features largely carry over, including multi-path heart rate tracking, SpO2 sensors now capable of continuous monitoring, ECG, skin temperature sensing, and comprehensive satellite positioning capabilities including GPS, Glonass, and Galileo. Notably, the watch adds satellite SOS support for emergency messaging without cellular coverage, akin to what is offered on some high-end competitors.
Battery capacity has been increased moderately: the 41mm model jumps from 307mAh to about 325mAh, while the 45mm version grows from 420mAh to around 455mAh. This boost translates to approximately 30 hours of battery life with always-on display enabled for the smaller model (up from 24 hours on the Pixel Watch 3), and up to 40 hours for the larger one, making it a notable improvement in daily endurance.
Software-wise, the Pixel Watch 4 will ship with Wear OS 6 and an updated Expressive UI, promising smoother animations and potentially better AI features powered by Google’s Gemini. The overall design remains conservative and familiar to Pixel Watch users, focusing on refinements and incremental performance and usability improvements rather than a radical redesign.
Google’s Pixel Watch 4 is expected to officially launch alongside the Pixel 10 smartphone series on August 20, 2025, with retail availability likely starting in October. The watch will compete with strong rivals like Samsung’s Galaxy Watch 8 and Apple Watch Series 10, offering a carefully calibrated upgrade aimed at existing Pixel Watch users and newcomers seeking a well-integrated Wear OS smartwatch.
Pixel Watch 4 refines the Pixel Watch formula with improved brightness, battery life, charging speed, and internal efficiency, while keeping a design close to the previous generation. This approach may appeal more to loyal users wanting stability and slight improvements rather than early adopters seeking bold new features.
