Dell Inspiron 15 7559 Review - Affordable, Upgradeable

Dell estimates the battery life of the Inspiron 15 7559 at about 11 hours, but that (and any manufacturer’s claim about battery life) is heavily dependent on a number of variables and can be hard to recreate. We measure battery life by running down the system’s battery in specific conditions and then comparing the results to those of systems we’ve similarly tested.

One of the tests we run is Battery Eater Pro, which simulates heavy, battery-guzzling usage. After charging the laptop to full power and reducing the display brightness to 50%, we let Battery Eater Pro grind the laptop’s battery down. We also run a less power-intensive test in which we refresh a Web page regularly for the life of the battery. This gives us a feel for how long the laptop is likely to last when handling less demanding tasks.

The Inspiron held out for 6 hours and 52 minutes in our Web browsing test, putting it near the middle of the pack. It took top honors in Battery Eater Pro, however, lasting for a total of 2 hours and 22 minutes. That kind of battery power ought to see you a day of travel, particularly if you can get to an outlet on a layover.

As for noise, the Inspiron 15 7559 is whisper quiet. You might hear the laptop when it’s under heavy load, but the noise doesn’t rise to the level of being distracting. It’s a quiet system overall.

Josh cut his teeth (and hands) on his first PC upgrade in 2000 and was instantly hooked on all things tech. He took a degree in English and tech writing with him to Computer Power User Magazine and spent years reviewing high-end workstations and gaming systems, processors, motherboards, memory and video cards. His enthusiasm for PC hardware also made him a natural fit for covering the burgeoning modding community, and he wrote CPU’s “Mad Reader Mod” cover stories from the series’ inception until becoming the publication editor for Smart Computing Magazine.  A few years ago, he returned to his first love, reviewing smoking-hot PCs and components, for HotHardware. When he’s not agonizing over benchmark scores, Josh is either running (very slowly) or spending time with family.
