battery info gone after recent update

Background: I use i3status to display battery info (but the situation is the same no matter my Desktop Environment / WM (i.e. battery info is also gone in XFCE, Cinnamon, Gnome, etc). It was working fine in September. This month, ran pacman -Syu, rebooted, and battery info is gone.

I have two identical systems (old Intel BayTrail-based tablets). On the pre-upgrade box (which still shows battery info), I have these:

/sys/class/power_supply/axp288_fuel_gauge
/sys/class/power_supply/axp288_charger

On the post-upgrade box (no more battery info), I only have

/sys/class/power_supply/axp288_charger

If i do this on both:

lsmod | grep 288

the results are the same (although the order is slightly different):

axp288_charger   24576  0
extcon_axp288          20480  0
roles                  16384  1 extcon_axp288
axp288_fuel_gauge      28672  0
axp288_adc             16384  0
industrialio           90112  5 axp288_adc,industrialio_triggered_buffer,kfifo_buf,axp288_fuel_gauge,bmc150_accel_core

Not sure what caused "axp288_fuel_gauge" to disappear. In a fresh install, "axp288_fuel_gauge" is missing also.
Any ideas?

Re: battery info gone after recent update

The only thing I konw is, apx288 is the power-mananging chip on the mainboard, it also appears on cherrytrail tablets' mainboard.

If a fresh reinstall cannot solve it, maybe something changed in i3wm with some new updates?

On my apollo lake N3450 and a N4200 processer laptop,(known as new generation of atom cpus after cherrytrail), i3wm is ok of battery-info.

yeah... it's nothing specific to i3 - as mentioned, even with a full-blown desktop environment, battery info is still missing.
What do you have listed in here?

/sys/class/power_supply/
