Long battery life isn’t strictly necessary no, but it’s nice. A lot nicer than one might expect. It can make the difference between needing to bring a charger or not, plus it’s one less mental background daemon to keep running (thinking about how much life is left, where the nearest outlet is, etc). Arguably the bigger impact of long battery life is how it’s no longer necessary to throttle the system when it’s unplugged to not burn through battery in an instant. The performance of plugged and unplugged is identical.
