I always thought that the previous way was way too simple but this new way, I haven't yet gotten the hang of it. Would be nice to click on the graph and drag to compare points of usage - also more clear when the phone hits 100% would be nice. Still getting used to it. Shouldn't be that hard to have lifetime stats too! Would love to save this data.
For now, coconutBattery is still where I go for all my battery data.
