A:AnswerThe same thing has happened to my Fitbit! My versa 2 lasted me over a year but yeah, the newer ones have a limit of battery life. It requires the customer to purchase another Fitbit. That's how they make money.
A:AnswerIt measures pulse, but not BP (as an RN it's unlikely the latter would be accurate if it did). Out of the box, it does track sleep, and provides sleep stages and heart rate variability. I believe you'll need to convert to premium at 6 months to continue receiving detailed sleep information (I haven't yet past that milestone), but at least you'll be able to see if this information is of value to you. You'll need to download the Fitbit app on your smartphone, and create an online account, linking your device, to get full download data.
A:AnswerYou can see your steps, "zone minutes", distance, calories burned, heart rate and resting heart rate, hourly activity, most recent sleep score, SpO2%, and number of times you've exercised out of your set goals on the screens on the Charge 5.
