Really? Slice battery on a Lenovo X220+9 Cell gives you 20 hours. I haven't seen any manufacturer come near that number. Macbook can't reach it either. Or a T420 with slice gives you even more I think. Remember there is a big difference between Lenovo IdeaPads and ThinkPads, just like there is between HP Pavillions and EliteBooks.
