Dell XPS 15 (L501X): Intel Core i7 840QM/2GB nVidia GT435m Review

Battery life of a 15inch laptop is very important, especially if you are a business man and frequently checking email and working in Microsoft Office.

To test the battery today we put the machine through two sets of real world situations. One as a gamer on the move, who wants to play games on a train journey or bus with two thirds screen brightness. Secondly as a business man, using the machine for productivity with wireless enabled and balanced power settings with a mid way brightness setting.

The 56Wh battery proves to be more than capable of powering this system for around 3 hours 15 minutes under light, general use, which is a great result. When gaming, we managed to get just over 2 hours out of the battery before the machine would shut down.
