I sure expected that the batter would last longer than it does. The headset is great, more comforable than I expected and easy to use and it set up with my phone on the first try.When I was reviewing them before buying one, I was under the impression that it had some 20-30 hours of standby life and up to 6 hours of talk time. I might be mistaken now, but I sure don't get that much out of it. Thankfully it's only one AAA battery. I think I'd rather replace a battery than have to recharge it because I can always keep a spare battery handy.
