           Summary: GTA01v4 Only Charges at 40ma
           Product: Neo1973 Hardware
           Version: GTA01v4
          Platform: Neo1973
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: PMU (Power Management Unit)
        AssignedTo: sean_chiang at fic.com.tw

Tests done with my two GTA01v4 and repeated by other on #openmoko show that the
device only default charges at 40ma and not 100ma as advertised. This is a big
problem when the GSM modem is still on as that alone draws about 30ma leaving
only 10ma to charge the battery. In any case, 40ma instead of 100ma means it
takes 2.5
times as long to charge the neo from the off condition. 

Test setup - milliampmeter in series with USB +5 from multiple machines.
