Depends on what you're doing with it... is the backlight on all the time... making a call... I can't give you a straight answer because I didn't examine this yet. Instead I spent all my time around power consumption looking to optimize suspend current since that can involve circuit changes. For suspended time with GSM modem off we have the consumption down to ~2mA and I expect that will improve further by software changes, so on a 1200mAh battery like we ship maybe it can last 20 days (unverified!) doing nothing at the moment. With GSM modem on in suspend maybe 5 days (unverified!). Whatever the figure is for "usage time" it will change by a factor of 5 or 10 depending if you run the GSM transmitter, wifi, CPU is always busy, GPS, and the worst suspect the backlight, so you need to define exactly what you do with the device during this "usage" to get a meaningful figure. Generally I would expect over time we can improve performance in software, like dimming the backlight gently quite soon after the last action, getting the backlight off quickly, and getting into suspend quickly between actions from the user. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFHyMMeOjLpvpq7dMoRAvH0AJ0W31ZuOOkLRyvKfy3PnoNs/Frg6wCfRxNq 5ycuT6jUOoRAK9pOGRPTMk4= =FB4L -----END PGP SIGNATURE----- _______________________________________________ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
