On top of that, a Li-Polymer battery retains up to 80% of its original charge capacity even after hundreds of charge cycles so you won't have to worry about deteriorating battery performance. Thanks to a clever combination of hardware and software optimization, the battery adheres to the highest battery safety standards and gives you optimal charging performance to prolong its lifespan.

Stays Cool,Even After Hours of Use

ASUS IceCool Technology gives X Series a unique internal design that addresses uncomfortable heating issues by preventing heat build-up under the palm rest. This keeps the palm rest surface between 28°C to 35°C – significantly lower than body temperature. This exclusive internal layout places heat producing components away from you, and when combined with exceptional cooling from the heat pipes and vents, ensures you stay comfortable even after long hours of use.
