Hellow friends I am share my own experience in asus vivoBook U38N. So lets start at first I should talk about its battery drained it back up not more than 3 hours which is very short time for a laptop it also takes more than 6 to 7 hours full charged . It leg many time while playing high definition games and full hd or 4k videos more one thing I could consult about that is its audio quality its audio is very dim and not clear which is very disappointing factors in this laptop. So according to me one can get a much better laptop in this price from hp or dell.
