Powermark Battery Performance


PMark_Logo

The purpose of the workloads is to simulate realistic usage scenarios of portable computing devices. Short test scenarios are looped until the per-iteration run time (five minutes by default) is reached or the battery charge end condition is met. The workloads selected for the benchmark are run in order, each workload once per iteration. Iterations are run until the battery charge has dropped to the desired level or the benchmark is cancelled. Once the battery charge end condition has been met Powermark generates a result based on the time elapsed and battery charge consumed by the workloads. In order to maintain the specified workload weighting the results of the final iteration (during which the battery charge fell to the desired level) is ignored.

Web browsing

The web browsing workload opens Internet Explorer and serves content from a local custom-made web server. The content is a modified version of Peacekeeper 1.0 Community site test. The computational load is mostly JavaScript based and performs following tasks:

  • Encryption
  • XML parsing
  • Data filtering
  • String sorting
  • Window scrolling
  • Word processing workload

The word processing workload is a text editor look-a-like application. It is implemented using RichTextBox control in Windows Presentation Foundation (WPF). Typing in the editor is simulated and throttled to match typing speed of a user. The workload content is based on a Wikipedia article on batteries.

Video playback

The video workload simulates watching movies on a portable device.

Clip details:

  • Codec: H.264
  • Duration: 8:43
  • Resolution: 1280 x 720
  • Frame rate: 25 frames per second
  • Bitrate: approx. 5000 kbps.

Gaming 

The gaming workload renders a DirectX 9 Shader Model 2.0 scene to simulate the graphics workload of a mainstream game. The scene features cascaded shadow maps and high-resolution shadow mapped point lights.

Whilst Powermark shows that the Ativ Book 9 Lite offers up to just under 6 hours of battery life from a single charge, we found that with moderate use throughout the day, it is possible to get up to eight hours of use out of the battery. Simple steps such as dimming the screen, disabling the WiFi when out and about and setting the laptop into quiet mode where it disables the fan are just an example of how you can increase the length of time that you can get out of a single charge.
