As a matter of fact, I think Hungry-nim checked the battery life with Battery-pack 4.0 (which I'm using now) Unfortunately that's not the correct battery life for AXIM. As you know, a new batterpack 4.1 only supports batter-life in AXIM. You might want to download a new version and test it again. If you have beeen using a new batterypack, I was wrong. Just ignore this article.
