Key Differences
Xiaomi's 15-day battery life more than doubles Fitbit's roughly 6-day figure, a significant practical difference for anyone who finds themselves frequently forgetting to charge a smartwatch. Fitbit's advantage is its much longer-established fitness app and community features, plus tighter integration with Google's broader ecosystem now that Fitbit is owned by Google — features Xiaomi's watch doesn't attempt to replicate to the same degree.
