What it is and who it fits

The Fitbit Charge 6 is a health and fitness tracker with built-in Google apps such as YouTube Music, Google Maps and Google Wallet. It suits users who want daily activity monitoring, heart-rate tracking and smart notifications on a lightweight aluminium case. A six-month Premium membership is included for deeper insights and guided workouts. A Google account and compatible phone running the Fitbit app are required for setup.

Practical limits of the platform

The tracker stores seven days of minute-by-minute motion data and thirty days of daily totals. Heart-rate data is recorded at one-second intervals during exercise and five-second intervals otherwise. Battery life reaches up to seven days, though always-on display and SpO2 use reduce that span. Water resistance is rated to 50 metres. The side button provides quick navigation to the home screen and stats.

Capacity and headroom

The AMOLED display measures 0.44 by 0.91 inches within a 1.45-inch long case weighing 0.066 pounds. Small and large bands are included, fitting wrists from 5.1 to 6.7 inches and 6.7 to 8.3 inches respectively. Over 40 exercise modes cover a wide range of activities, while built-in GPS and GLONASS handle outdoor tracking without a phone. The package also contains a charging cable.

Questions about this item

Which band size should I pick for my wrist?

The box includes both a small band for wrists 5.1" to 6.7" and a large band for wrists 6.7" to 8.3". Measure your wrist and choose the size whose range covers your measurement.

What does the seven-day battery claim mean in daily use?

Up to seven days on a single charge with typical use; always-on display and SpO2 tracking will shorten that, so charging every few days keeps tracking uninterrupted.

How deep can I take the tracker and still have it work?

Water resistance is rated to 50 meters, so it handles swimming, showering and rain without issue.
