Versa Lite is advertised as "4+ days" battery life. So 3 days sounds a bit short but not terrible. Versa 2 has a bigger battery and is advertised as 6+ days.
If you have your screen brightness turned up, or screen timeout to be longer than 10 seconds, or many app notifications, or a clock face that does a lot of background tasks, then battery life will be impacted. I have an original Versa (v1) that is over 1.5 years old, and I get about 4 days battery life (auto-brightness, 15 second screen timeout, but only a handful of app and text notifications per day, and clock face that gets the current weather conditions every 60 minutes).
