Operation voltage Fenix5X

Hi. Anyone know the internal operation voltage of Fenix5 watches? (NOT charging voltage)
Asking because there is a limitation offshore for smartwatches and watches with operation voltage over 1,5V.

I really don't consider F5 to be a smartwatch like f.ex Apple watch or Samsung Galaxy watch wich use much more power, and by far not as solid as F5.

    The F5 is powered by a li-ion battery, which has a nominal voltage of 3.6V.

    like f.ex Apple watch or Samsung Galaxy watch wich use much more power,


    Power is not to be confused with voltage. I bet that both apple and samsung are powered by a 3.6V battery as well. How much power they draw is a completely different thing. I assume that an F5 with bluetooth and GPS turned on is not much more power efficient than an apple.

    Are you sure the limitation is about 1.5V and not 1.5A?

    I know very well the difference between power and voltage. Power (W) is a result of current and voltage P=U*I and my point was that Apple and Samsung use more power due to their screens, etc and has to be recharged much more often. The limitation is 1.5V (typical quartz power source), and if above they consider it an ignition hazard no matter the current. My argument is that even if F5 uses 3.6V they are MUCH more solid built than f.ex apple watch and should not be considered as a hazard. But as long as they are not Ex-certified I guess I just have to find another watch to use at work. Too bad because I like to log pulse, steps, floors, etc during the day.
