I had the OG Bip and got extremely close to 3 months at one point. Unfortunately I don't remember if I had the HR set to 5 minute intervals but if it was on, I think that was the setting. Even with 1 minute intervals though, battery life was absolutely stellar. I'd often lose my charger, and in few days after I saw the battery dropping/low battery alerts, I'd find it too (before the watch died)!
