Inspire 2 has up to 10 hours of battery life. A lot of walking can be done in that amount of time. I could walk downtown and back with that battery! 20+ goal based exercises inside. Basically, I just walk but others may like some hints to what can be done and Inspire 2 will track automatically your activities. Do you like to swim? This one is for you. It’s waterproof, how cool is that? That counts in the shower too.
It depends on how active you are but a heck of a lot of movement can be tracked in that amount of time.
