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?

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

Hi, Philip Rhoades p...@pricom.com.au writes: - Even with the dumb battery configuration, the battery charging animated icon continues after USB (power) disconnection - should that happen? Provide uevent files contents for both the battery driver and pcf50633-mbc drivers. - 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? Those files are always present in the sysfs, kernel maintains them automatically for every driver. - The discharge rate attached for an inactive phone (with a blanked screen) with a new, fully charged battery is not very good (~10 hours) Keep in mind that the SoC was constantly running during that test, so this should be ok. 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.
