Tracking Battery Usage

[stockcerts]

Which app would you suggest for tracking battery usage? My usage is horrible and I'd like to determine if their is any one app (or more) that is causing my problem. I've seen several battery apps that are available, so thought I'd ask for a recommendation.

Thanks!

You say you have an iPhone 3GS?? In that case you wont need a battery app. There's an option in settings (I think it's under accessability) that's let's you display a battery percentage next to the battery sign in the top right corner. This percentage is every 1%. I'm pretty sure that this option is not default, so try turning it on hope this helps
