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 at 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 at n900:/my/tui/ofone# echo 500 > /sys/class/power_supply/bq24150a-0/current_limit
root at n900:/my/tui/ofone# ./tefone
Ready.
Battery 3.994 V 4.034 V 78 % 0 % 0 / 0 / 2056 mAh Full -251.506 / 550 / 500 mA
Battery 4.0 V 4.037 V 79 % 0 % 0 / 0 / 2056 mAh Full -223.125 / 550 / 500 mA

Battery 4.005 V 4.023 V 79 % 0 % 0 / 0 / 2056 mAh Full -223.66 / 550 / 500 mA
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
