Fitbit Charge 6: What to Know

Fitbit's Charge line has been the default recommendation for band-style trackers for years, and the Charge 6 keeps that reputation mostly intact by adding Google's ecosystem on top of the usual Fitbit basics. It has a 1.04-inch AMOLED touchscreen, a physical side button borrowed from the Pixel Watch for easier navigation, and Amazon listings and Fitbit's own marketing both cite up to 7 days of battery life, though that figure assumes the always-on display is switched off; leaving the screen on constantly will noticeably shorten it, which is worth knowing before you buy.

On the sensor side, the Charge 6 includes continuous heart-rate monitoring, an SpO2 (blood oxygen) sensor, a built-in ECG app for checking heart rhythm, an EDA (electrodermal activity) sensor for stress readings, and skin-temperature variation tracking, layered on top of step counting and sleep-stage analysis. It's also the only tracker in this roundup with genuine built-in GPS, meaning it can log pace and distance on a run without your phone in your pocket, plus Google Maps and Google Wallet baked directly into the device. Water resistance is rated to 50 meters, so showering and swimming are both fine.

The catch, and it's a real one, is that Fitbit gates some of its more useful features behind a subscription. Basic activity, heart rate and sleep data are all free to view in the app, but the Daily Readiness Score and several of the deeper health insights require Fitbit Premium, which Google has been rebranding to Google Health Premium and pricing around $9.99 a month or roughly $99.99 a year as of 2026. That's an ongoing cost worth factoring in if you want the full experience rather than just the raw numbers.
