I bought a Dell XPS 15 L502X two weeks back with a 9cell battery. At first it gave 6 to 7 hours battery backup. But now it gives hardly 2 to 3 hours. My use is just basic like listening to music, watching movies etc. At screen brightness to 10% and balanced power mode. I contacted dell regarding the same, they say the battery can not be replaced, as it would be done only when the battery is not charging at all or damaged. Im deeply worried, its just 2 weeks old.
