Make every beat count with Fitbit Charge 2™—the all-new heart rate and fitness wristband built for all-day, workouts, and beyond. PurePulse continuous heart rate makes it easy to maximize workouts, better track calorie burn, and get a snapshot of your cardio fitness level, while all-day activity and auto sleep tracking, lets you see how your whole routine adds up. Record your workouts with multi-sport modes to see real-time workout stats on screen, or rely on SmartTrack to automatically record select exercises for you. The large OLED display helps you stay connected with call, text and calendar alerts, stay active with Reminders to Move, and find moments of calm with personalized guided breathing sessions. Plus, you can find a look that fits your style with customizable clockfaces and interchangeable bands. With more advanced features in a sleeker package, it's the motivation you need to push yourself further-every step, every beat, every day.

Like all heart rate tracking technologies, accuracy is affected by physiology, location of device, and different movements. Learn more about wear during workouts.
Battery and power:
We recommend charging your device every few days to ensure that you're always tracking.
Battery life up to 5 days. Battery life and charge cycles vary with use, settings, and other factors; actual results will vary.
Fitbit Charge 2 is sweat-, rain-, and splash proof. However, the device is not swim proof or showerproof. With any wearable device, it’s best for your skin if the band stays dry and clean.
If the band gets wet or if you sweat in it, remove and completely dry the band before putting it back on. Give your wrist a rest by taking the band off every now and then.
The Fitbit Charge 2 wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. Fitbit Charge 2 also has a surgical-grade stainless steel buckle.
Syncing & Notifications
Using Bluetooth LE wireless technology, Fitbit Charge 2 sends smartphone notifications and syncs automatically to computers and 200+ leading iOS, Android and Windows devices. Certain features like smartphone notifications or Connected GPS may require Android 5.0+.
