Of course, the two tests I am trying to compare have different goals. Battery Eater was originally conceived as a program to put every computer subsystem under the maximum workload to produce the minimum time this notebook can work on its batteries. Mobile Mark, on the contrary, emulates an average user – that’s why so much third-party software should be installed before testing. Moreover, the test makes regular pauses in work as if this average user went away from the computer. As a result, both programs measure the notebook’s operational time until the batteries are completely discharged. Battery Eater also provides a battery discharge graph, while Mobile Mark – the system performance rating. I will discuss shortly how you can use Battery Eater to check the performance of your system.

Both tests can measure the notebook’s battery life time in the text “reading” mode. Battery Eater uses an integrated module for text browsing and includes a text of “Hamlet, the Prince of Denmark”, in English, of course. Mobile Mark reads “War and Peace” in English, in Netscape Communicator 6.0. Besides that, Battery Eater will again show you the battery discharge graph.

This is where Mobile Mark’s capabilities end, while Battery Eater can offer some more interesting things.

Besides the above-described modes, Battery Eater features the so-called Idle mode when it doesn’t put the notebook under any serious workload, but only writes a small file onto the HDD every minute and shows the battery charge level. What is this test mode for? First, you can estimate the time the notebook can last in the idle mode (there are variants – with the display turned on or off). Second, you can see how long you can work in your favorite applications. The results are the same: the time until the notebook’s shutdown and the battery discharge graph.

Battery Eater can measure your system performance, for each subsystem independently. The program also comes with an easy-to-use independent module to sit in the Tray next to the clock and show you the current battery charge level.

Setup and Startup

After copying the program files into a folder on your hard disk (it is recommended to use only Latin letters and digits in the name of the folder), you run the BEPro.exe file.

The main window tells you about the current power source, the battery status, the battery charge level. You will also see the elapsed time and the estimated time left in this window during tests.

Clicking the Info button, you open a window with a list of all main subsystems in the left part and detailed info about the selected subsystem in the right part of the window.

When you select the Performance item, the Test button appears in the bottom of the screen. Clicking it starts benchmarking the performance of the computer subsystems (CPU, graphics, RAM, HDD). The results will be displayed in the right part of the window.

You can save the system configuration and the performance results in a HTML file by clicking the Report button and typing in the name of the file. After saving, the program will show you the report file in your default browser.
