Lenovo ThinkPad W550s Ultrabook Mobile Workstation Review

Battery Life

To measure the Lenovo ThinkPad W550's battery life in a controlled environment with consistent workloads, we turned to Battery Eater Pro. This test is designed to tax a laptop’s resources to give a feel for how long the laptop’s battery will last under heavy use. For the test, we set the laptop's display to 50 percent brightness and enabled WiFi.

Heavy and Light Loads


In our light duty web browsing test, we're refreshing web pages on the ThinkPad W550s with its panel brightness set to 50 percent and WiFi enabled as well. In this case, the CPU's only load is to stream and render a web page every few minutes. GPU, storage subsystem and memory use is limited. 

Without a doubt, the Lenovo ThinkPad W550s has killer battery life, thanks to the extended battery pack. You pay for it with added weight and a slightly bulkier notebook than you’d get if you opted for the machine's standard battery. However, given the freedom the extended battery provides, it’s hard to see how you wouldn’t opt for it while configuring your system. In fact, this machine puts a hurtin' on the likes of the Dell Precision M3800 when it comes to battery life.
