    On notebooks, you can often use

    pavel@amd:/data/l/linux-msm/arch/arm/mach-msm$ cat
    /proc/acpi/battery/BAT0/state
    present: yes
    capacity state: ok
    charging state: charged
    present rate: 0 mW
    remaining capacity: 71830 mWh
    present voltage: 16277 mV

    ...present rate is often usable-enough.
