During testing, the Pixel Watch 3 reliably tracked REM, light, and deep sleep phases, offering actionable insights into sleep quality and patterns. However, the need for daily charging due to its 24-hour battery life can be inconvenient for users seeking a longer-lasting solution.
This limitation means that users will need to consistently remember to charge the device during waking hours. Additionally, while the watch integrates well with Google’s ecosystem, including Google Fit, its compatibility with third-party applications is less robust.
This may restrict customization and personalization options for users who prefer diverse app ecosystems. Overall, its strong integration with Google services and accurate tracking make it a top choice for those deeply embedded in the Google ecosystem.
