I brought a new laptop with i5 1035GI processor, 8 gigs of ram, nvidia geforce mx330 graphics. The laptop has a 2-Cell 32 Wh battery. The laptop is good all around but the battery life is very poor. After a full charge it just lasts one and half hour. I dont know if it is to be expected from a computer with the given specs or if the battery is somehow damaged. Any suggestions? Also, my laptop is Asus vivobook X509JP.
