A:AnswerIf your phone has a wireless power share option, you should be able to use your phone to wireless charge your phone. I have the Galaxy 10+ and have used it to charge my watch in a pinch. The watch does, however, charge faster with the charger that comes with it.
A:AnswerI haven't been outside the United States with my watch. But, wherever you're wearing any smartwatch it will adjust as long as you have your phone with you.
A:AnswerHey there! The Galaxy Watch Active is able to connect with devices that run on Android OS 5.0 and above with at least 1.5GB RAM. Thank you for reaching out to us. ^Kayla
A:AnswerYes it is. It is very accurate and can help with health tracking. Even sleep tracking. You'll be charging every other day though if you track health and have it linked to text and calls. It really is great first smart watch.

A:AnswerMarta, I synch my watch with my Galaxy phone since I've had the S7Edge and use a phone app called Samsung Health. Once you enter your data, this application is very helpful by organizing your data and letting you know how you are doing with sleeping, eating, caloric intake, drinking water, exercise, vitals and more. You can set the watch up to display this information on a variety of watch faces. I've never tried to set an audible alert, but since you mentioned this, I will. I hope this helps you decide what you'd like.
