Google is set to introduce Gemini support to Wear OS smartwatches, replacing the existing Google Assistant. This transition follows Google's plan to fully transition to Gemini, starting with Android phones and expanding to tablets, Android Auto, headphones, Nest speakers, Google TV, and smartwatches. Insights from 9to5Google suggest that Gemini may be a straightforward app enhancement rather than a radical overhaul. The Pixel 9a features a Tensor G4 chip but has limited AI capabilities due to its 8GB of RAM, while the Pixel Watch 3 has 2GB of RAM and older Arm Cortex cores, which may hinder Gemini's performance compared to Assistant. There is potential for improved interaction with applications through Gemini extensions, but true Gemini Live-style conversations on smartwatches may not be feasible without significant battery drain. Future iterations of the Pixel Watch may showcase enhanced Gemini capabilities, especially with a new Wear OS chip expected from Qualcomm, but Google's current focus is on ensuring Gemini operates effectively on existing Android watches.
