Hi!
I connected N900 with full battery using USB. For some reason, charge limit was set to 100mA, battery was "full" and was discharging:
root@n900:/my/tui/ofone# ./tefone Ready. Battery 4.017 V 4.039 V 81 % 0 % 0 / 0 / 2056 mAh Full -242.224 / 550 / 100 mA
I adjusted the current limit, but got no change, battery is still discharging, fast:
root@n900:/my/tui/ofone# echo 500 > /sys/class/power_supply/bq24150a-0/current_limit root@n900:/my/tui/ofone# ./tefone Ready.

I'm getting a lot of
[ 208.037719] bq27x00-battery 2-0055: battery is not calibrated! ignoring capacity values [ 238.038024] bq27x00-battery 2-0055: battery is not calibrated! ignoring capacity values
messages, that's why all the 0s in battery information dump.
Any ideas?
Thanks, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
