Normal usage assumes you use suspend-to-ram when you do not actually interact with the device, that should give ~70 (without #1024 fix) or ~140 (with it) hours of "standby time". > - Should the phone be shut down after the "dumb" battery is fully > charged? No, charging is the same for gta02 battery and the dumb one, it's safe and doesn't require manual intervention.

I would guess not, because the ".0" at the end of bq27000-battery.0 suggests that there might be multiple battery instances, of which, at a given moment, some might be bound and others not. > If not, > don't the files only need to be created once instead of repeatedly each time > the scripts/aliases are run? Are you thinking that those echo commands create the files? I doubt it works like that; files in /sys and /proc are special, and it's more like echoing something into them causes some action to happen, or some config change. Cf. "echo 1 > /proc/sys/net/ipv4/ip_forward" to enable IP forwarding. Regards, Neil ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
QtMoko v33 - More battery info and questions
People, Using: echo bq27000-battery.0 > /sys/bus/platform/drivers/bq27000-battery/unbind modprobe platform_battery allows me to check the value of: /sys/class/power_supply/battery/capacity and using: rmmod platform_battery echo bq27000-battery.0 > /sys/bus/platform/drivers/bq27000-battery/bind restores the "smart" battery function. I attach a graph of the resulting discharge rate of the fully charged Nokia BL-6C battery. Questions: - Even with the "dumb" battery configuration, the battery charging animated icon continues after USB (power) disconnection - should that happen? - Using the methods above, both "bind" and "unbind" files exist in the driver directory - shouldn't there be only one at any one time? If not, don't the files only need to be created once instead of repeatedly each time the scripts/aliases are run? - The discharge rate attached for an inactive phone (with a blanked screen) with a new, fully charged battery is not very good (~10 hours) - I would need at least 24 hours with light usage to be able to use the Neo as my regular phone. Is this battery performance typical? - Should the phone be shut down after the "dumb" battery is fully charged?
