A:AnswerNo, I have not been successful in using the Charge 3 adapter on the Fitbit Charge 4 device. The Fitbit Charge 4 power adapter has a small gray band near the adapter end identifying it as a Charge 4 adapter.
A:AnswerAs far as I know. To get all of the features you must have the latest OS for your phone . I use IPhone 7plus and it’s flawless. I also get emails, text messages, and phone call notifications.
A:AnswerYes it keeps track and allows you to see exactly where you are on the 250 steps. It also alerts you 10 minutes to the hour if you are short so that you can/will get up and move
A:AnswerYes. You can expect the Fitbit Charge 4 to include call, text, or app notifications, Spotify connectivity, tap-to-pay, swim-proof capabilities, and more features.
A:AnswerI am left handed so I wear my Fitbit on my right wrist. Just remember to change the setting in the watch to your dominant arm if you are right handed.
