Surprising Fitness Tracker Battery Life: Fitbit Charge 6 vs Pixel Buds Pro 2 - Tested In the world of wearables, battery life is the unsung hero that keeps our tech gear constantly connected. While the Fitbit Charge 6 steals the spotlight with its 7-day battery that defies expectations-thanks to GPS tracking, 24/7 heart rate monitoring, and seamless Google app integration-it's not the only contender. The Pixel Buds Pro 2, though primarily a headset, surprises with its 12-hour charge, offering audio-centric endurance that still holds its own in the fitness tech arena. But beyond these two, the Fitbit Inspire 3 and Garmin HRM-Dual provide unique value: the Inspire 3's 10-day battery shines for stress and sleep tracking, while the Garmin dual-heart-rate monitor doubles as a reliable, standalone tool for runners and gym enthusiasts. As the battle for endurance rages on, it's clear that battery life isn't just about hours-it's about matching your lifestyle, whether you're chasing a marathon or a midnight workout.
