Description (last modified by jg) (diff)
All three units were taken for a one hour 40 minute walk over outback terrain. During the walk, psu_0/capacity_percentage was logged along with wireless signal and noise level. The other battery monitoring parameters were not logged. Each unit experienced the same usage pattern as part of a structured coverage test, beginning with fully charged battery, according to the monitoring parameters.
On unit Quozl 3, the battery capacity remained at 100% throughout, and when it was returned to AC adapter power showed a green battery light, and the battery status showed "full".
On unit Quozl 2, the battery capacity declined as expected, and when returned to AC adaptor power showed a red-orange battery light, and the battery status showed "charging".
On unit Quozl 1, the battery capacity declined as expected, and when returned to AC adaptor power showed a light-orange battery light, and the battery status showed "charging".
All three units are on build 193 with A62 firmware.
