Track fitness for days with these trackers with the best battery lifeBest answer: Various fitness trackers provide excellent battery life, including the wearable devices shown here. You can choose from trackers with replaceable batteries that last for up to 18 months like the Withings Move or rechargeable batteries, such as the one in the Withings Steel HR Sport, that can last up to 25 days.
Months, not days or hours before needing a new battery
Battery life on both fitness trackers and smartwatches gets better with each passing year. Case in point is the Withings Move, which promises 18 months of operation before the included CR2430 button cell needs to be replaced. The advanced activity tracker has been designed for simplicity. In doing so, it looks like a traditional analog watch. Inside, it keeps tracks of walks, runs, sleep, swimming, and more. With the HealthKit-compatible Health Mate app, you can view your trends and improvements over time.
The Withings Move is offered in five colors. You'll also be able to custom design your wearable device...
