Power & Battery Consumption
To test power consumption, we removed the X460's battery and measured the power it drew from the wall. At idle, it consumed just 14 watts, the lowest level we've seen from a high-end device. That changed under load, as Core i7-2630QM processor slurped 81 watts, making the X-Slim X460 a fairly power-hungry device.
Above are the results from Battery Eater v2.70. The "stress" test represents a gaming scenario, if you were to play using the battery alone the X460 would only last a little over an hour. That said, few would use this notebook for gaming, making the "readers" test more relevant. In this scenario the X460 lasted 5 hours and 41 minutes.
