How Long Does She Last?

We are using the standard benchmark settings from Bapco, along with a few other minor system tweaks. The screensaver was disabled and volume was set at approximately 20%.

MobileMark 2002 utilizes the following applications:

  • Microsoft Word 2002
  • Microsoft Excel 2002
  • Microsoft PowerPoint 2002
  • Microsoft Outlook 2002
  • Netscape Communicator6.0
  • McAfee VirusScan 5.13
  • Adobe Photoshop 6.0.1
  • Macromedia Flash 5
  • WinZip 8.0

The white papers for MobileMark are available on Bapco's website should you want to read up on how this benchmark works. In the graph above, higher scores equal better performance.

The X41 has 3 battery options (outside of docking bay options): 4 cell primary battery, 8 cell primary battery, and a 4 cell Extended Life Battery. The 8 cell battery is the standard battery if you make a web purchase. It has the advantage of providing a rubberized grip strip, However, its longer battery life comes with a large size, compared to the 4 cell primary battery, which doesn't have any rubberized grip strip.


Left to Right: 4 cell battery, 8 cell primary battery, 4 cell primary battery with EL battery

The Extended Life (EL) Battery provides additional battery life outside of a primary battery by using the docking bay interface to supply additional battery life. The downside is that it increases the thickness and places the system on an incline.

Charge time for the batteries from 0% to 100% is as follows (real world numbers, not estimates):

  • 4 cell primary - 2 hours and 5 minutes
  • 8 cell primary - 3 hours and 55 minutes
