Results of the baseline battery tests started on July 13, 2007.


==7/13/2007==
This test used the first 20 XOs set up in group A. The test was intended to compare the effectiveness of the lithium batteries vs. the nickel metal hydride batteries, as well as the effect of having the backlight on or off. We used the program Logbat, which returns the battery's current charge every 20 seconds, to determine the lifespan of the battery. Once Logbat was running on all 20 XOs, we unplugged all the power cords and left the XOs alone overnight. The nickel metal hydride batteries were found to have major problems - most of them died within half an hour of the XOs being unplugged, and the few that lasted longer than that still had a shorter duration than most of the lithium batteries.

This test also used the first 20 XOs set up in set A and followed the same basic format as the test from 7/13, except that the first 10 XOs had their backlight turned off for this test rather than the last 20. Again, the nickel metal hydride batteries experienced had shorter lifespans, though far fewer of them died within minutes this time around. When functioning properly, the nickel batteries seemed to last about an hour shorter than the lithium batteries.

This test also used the first 20 XOs in set A and followed the same format as the first test, with one exception - A11-15 had their BYD lithium batteries replaced with Gold Peak lithium batteries. In this test, none of the nickel metal hydride batteries had an extremely short lifespan as was the case in the first two. However, average performance among both lithium and nickel metal hydride batteries was down significantly. This was due in part to several of the lithium batteries being changed to Gold Peak lithium batteries which, apparently, have considerably lower battery life than the BYD lithium batteries.

This test was originally intended to be more extensive, including 45 XOs between set A and set B, and testing the effects of DCON mode. However, due to an error in the test procedure not all of this data was abled to be gathered. We used the test as an opportunity to gather more data bout the nickel metal hydride batteries, using XOs 16 to 25 from the A set. Again, the NMH batteries displayed both general lower performance when compared to lithium, as well as several extremely short durations.

This test used was of both a larger scope and a different model than the previous tests. 45 XOs between sets A and B were used. A1-15 were left idle after using the command "xset dpms force off" which immediately turned off the screen's display and backlight. A16-A20 and B1-B10 were left idle after using the command "xset -dpms," which forces the screen's display to stay on even after 10 minutes of idling. A21-25 and B11-B20 were left idle after using the command "xset -dpms" and turning the backlight off. The test was designed to compare the difference in battery life with the screen's display and/or backlight on or off.

We found that, with both the display and backlight on, the battery life was shortened significantly (by 1-1/2 to 2 hours on average). With the display on and the backlight off, the hit was far less significant (about 1/2 hour).

This test was originally intended to be more extensive, including 45 XOs between set A and set B, and testing the effects of DCON mode. However, due to an error in the test procedure not all of this data was abled to be gathered. We used the test as an opportunity to gather more data bout the nickel metal hydride batteries, using XOs 16 to 25 from the A set. Again, the NMH batteries displayed both general lower performance when compared to lithium, as well as several extremely short durations.

This test used was of both a larger scope and a different model than the previous tests. 45 XOs between sets A and B were used. A1-15 were left idle after using the command "xset dpms force off" which immediately turned off the screen's display and backlight. A16-A20 and B1-B10 were left idle after using the command "xset -dpms," which forces the screen's display to stay on even after 10 minutes of idling. A21-25 and B11-B20 were left idle after using the command "xset -dpms" and turning the backlight off. The test was designed to compare the difference in battery life with the screen's display and/or backlight on or off.

We found that, with both the display and backlight on, the battery life was shortened significantly (by 1-1/2 to 2 hours on average). With the display on and the backlight off, the hit was far less significant (about 1/2 hour).
