Whoop 4.0 vs Whoop 5.0: our verdict

Whoop 5.0 makes the most sense if you want a lighter band and care most about longer battery life and faster charging, especially if charging every few days gets old fast. If a slimmer profile is your top priority, this isn’t the one to pick. The thicker build means it sits higher on your wrist than some might like.

Whoop 4.0 makes more sense for someone who cares most about a slimmer profile and wants the thinnest fit possible in a fitness band. The shorter battery means charging it more often, which can get annoying if you wear it heavily.
