Sorry, completely forgot to state what version of i3 I'm using:

local/i3-wm 4.7.2-1 (i3)
local/i3lock 2.5-2 (i3)
local/i3status 2.8-2 (i3)

Linux chromebook 3.4.0-ARCH #1 SMP Wed Jan 15 15:33:47 MST 2014 armv7l GNU/Linux

i3bar displays %status and %percentage fine, but for some reason %remaining, %emptytime and %consumption only show up if the battery is charging and has <100% of the design capacity.

I guess it has something to do with me running i3 on the Samsung Chromebook as battery has always been a little weird even with the xfce applets, but I can't find the culprit. Here's the relevant part of my .i3status.conf:

battery 0 {
    last_full_capacity = true
    format = "%status %percentage %remaining %emptytime %consumption"
    path = "/sys/class/power_supply/sbs-4-000b/uevent"
}

And here's the content of /sys/class/power_supply/sbs-4-000b/uevent @ around 97% (according to i3status) and charging:

POWER_SUPPLY_NAME=sbs-4-000b
POWER_SUPPLY_STATUS=Charging
POWER_SUPPLY_HEALTH=Good
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CYCLE_COUNT=42
POWER_SUPPLY_VOLTAGE_NOW=8550000
POWER_SUPPLY_CURRENT_NOW=1159000
POWER_SUPPLY_CAPACITY=97
POWER_SUPPLY_TEMP=311
POWER_SUPPLY_TIME_TO_EMPTY_AVG=3932100
POWER_SUPPLY_TIME_TO_FULL_AVG=1740
POWER_SUPPLY_SERIAL_NUMBER=1dc9
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=7500000
POWER_SUPPLY_VOLTAGE_MAX_DESIGN=7500000
POWER_SUPPLY_ENERGY_NOW=29540000
POWER_SUPPLY_ENERGY_FULL=32350000
POWER_SUPPLY_ENERGY_FULL_DESIGN=30600000
POWER_SUPPLY_CHARGE_NOW=3906000
POWER_SUPPLY_CHARGE_FULL=4242000
POWER_SUPPLY_CHARGE_FULL_DESIGN=4080000
POWER_SUPPLY_MANUFACTURER=SDI
POWER_SUPPLY_MODEL_NAME=4302D40

I assume i3status reads POWER_SUPPLY_TIME_TO_EMPTY_AVG for %emptytime, so it's there but for some reason only gets read when the charger is plugged in? The same goes for POWER_SUPPLY_TIME_TO_FULL_AVG, but at least that makes sense as I only want to see it when I'm actually charging.

(And in case you're wondering: POWER_SUPPLY_TIME_TO_EMPTY_AVG does decrease when you unplug the charger, so it's not some weird bug which keeps it a constant number)

Oh and last_full_capacity = true doesn't work at all for me. But it should, because the battery is regularly charging >100% and also acpi -V shows this output:

Battery 0: design capacity 4080 mAh, last full capacity 4253 mAh = 100%

Any ideas on how I could fix these things? What I need/want most is having %emptytime work, and %consumption would be nice but isn't a must.
