I've checked out the 2.6.28 kernel from the andy-tracking branch, and it does better. After 12 hours, there's still 37 % charge left in the battery with an estimated 7.5 hours left. Where the 2.6.24 kernel would draw 56 mA from a fully charged battery, the 2.6.28 kernel is down to 49 mA and with 37 % carge left, it is only up to 55 mA at 3.78 V. > IIRC, the parts that take power directly from the battery are GSM, the > audio amplifier and the vibrator motor. USB 5 V power supply too, btw. -- Rask Ingemann Lambertsen Danish law requires addresses in e-mail to be logged and stored for a year _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
