Eurocom M98NU XCaliber Gaming Notebook Review
Battery Performance and Power Consumption
Large form-factor, high-end gaming notebooks are not typically known for their battery performance. There are just too many power-sucking components for a battery to provide juice to for any significant amount of time--at least not without weighing the notebook down further with a ridiculously large and heavy battery. Being that the M98NU XCaliber has an 18.4-inch screen and dual high-end mobile GPUs, we didn't expect much from the M98NU XCaliber in terms of battery life.
As we predicted, the M98NU XCaliber's one hour of battery life is inline with the type of battery life we've seen from other gaming notebooks, such as the Alienware M17x notebook--which lasted only 4 minutes longer than the M98NU XCaliber.
We also wanted to get a sense of how much power the M98NU XCaliber consumes when it is plugged into a power outlet. Using a power meter, we measured power when the notebook was sitting idle (logged into the OS with no active foreground tasks) and when all four cores were busy with Cinebench's R10 multi-threaded workload.
When at idle, the M98NU XCaliber consumes about 65 Watts of power; while at load it consumes about 110 Watts. When powered off, it consumes only 1 Watt, and a mere 2 Watts when in sleep mode. These measurements were taken when the notebook was fully charged. When the notebook is actively charging it consumes 115 Watts when at idle, and 55 Watts when powered off or in sleep mode.
