Best answer: Various fitness trackers provide excellent battery life, including the wearable devices shown here.

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 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 being offered in five bright colors at launch. Later this year, you'll also be able to custom design your wearable device by selecting from different dials, cases, activity hands, and wrist bands.

Other wearable devices to consider

The Misfit Command and Moov 3D also include replaceable batteries with long battery life. The former, which is a smartwatch includes a CR2430 coin cell battery that lasts up to one year, while the latter offers a CR123A battery that runs for up to six months. The Garmin Vivovit 3, meanwhile, includes a CR1632 battery that will also last for up to 12 months.

If you're looking for a fitness tracker with a rechargeable battery, consider the Fitbit Charge 4 (one week between charges), and the Withings Steel HR Sport (25 days).
