Question: what is the difference between fitbit versa 2 and 3?
Answer: Despite being the smaller device, the Charge 3 actually has better battery life than the Versa. The Charge 3 gets around 7 days on a single charge, while the Versa is 4 days (give or take). If you travel a lot or don't want to constantly worry about charging your device, the Charge 3 is probably the better pickup.
