A:AnswerI do know that they can be refurbished but I'm not sure if this includes a new battery. My battery die in my Fitbit 2 and I opted to move up to the Fitbit 3 while they were sold new at a discount. I'm glad I did. It works so much better with the app and the new features are great!
A:AnswerThe Charge 3 is supposed to be water resistant, so I would contact Fitbit to see if they would honor the warranty, even if you've had it for a little bit more than a year
A:AnswerThis fit bit is very new to me so I Dk all it’s features. It tracks sleep, cardio, fat burning but I haven’t seen deep breathing. I’m sorry I can’t be more helpful.
A:AnswerI’m only getting familiar with this devise but I think it tracks the distance. I Think that is cumulative for the whole day on the device but I Dk if you can see a run on the phone fit bit app.
