To complete our testing, we ran Battery Eater Pro to get a feel for the Qosmio X305-Q725’s battery performance. We used Battery Eater's Classic and Idle tests. Under the Battery Eater Idle test, the system idles until the battery drains. We also ran the Battery Eater Classic test, which stresses the CPU and GPU to full load until the battery runs out of power. During both tests, the wireless radios were enabled.
The battery life for most desktop replacement notebooks is short. Because these systems require so much power, most users expect to be tethered to a power outlet the majority of the time. The Qosmio X305-Q725 provided about an hour and ten minutes of battery life while idle. Under load, the laptop's battery lasted for about 47 minutes. These times are a bit short, but they’re not too far from what we would expect from a desktop replacement. If you’re simply looking for a high performance gaming laptop for occasional portability and the ability to easily move your rig from place to place without a mess of cables, the Qosmio X305-Q725 will do just fine.
