High performance and long battery life are generally mutually exclusive..... Optimus Technology does a lot to change that....you can read about it here:

CLEVO is a large Taiwanese computer company specializing in laptops. While the Clevo brand name is perhaps not widely known, their products are re-branded and sold by known boutique brand OEMs (Original Equipment Manufacturers)… notably Sager, VoodooPC, Falcon Northwest, Eurocom, etc. They are also considered (by whoever knows about notebooks) to design and manufacturer the best of the best notebooks in terms of superior build quality and innovative designs.
If ya thinking ya never heard of them, well I bet you would say the same about the brands ya do kno (HP, Lenovo, Sony, Dell, etc) cause none of them actually makes a laptop....they are all made by ODM's. The vast majority of laptops on the market are manufactured by a small handful of Original Design Manufacturers. Major relationships include:
Quanta sells to (among others) HP, Lenovo, Apple, Acer, Toshiba, Dell, Sony, Fujitsu and NEC
Compal sells to (among others) Acer, Dell, Toshiba, Lenovo and HP/Compaq
Wistron (former manufacturing & design division of Acer) sells to Dell, Acer, Lenovo and HP
Inventec sells to Toshiba, HP and Lenovo
Pegatron sells to Asus, Toshiba, Apple, Dell and Acer
Foxconn sells to Asus, Dell, HP and Apple
Flextronics (former Arima Computer Corporation notebook division) sells to HP
