Please feel free to reopen it if the problem still exists with the latest upstream kernel.

Sorry for the delay: yes, I can confirm that using the latest ISO (android-x86_64-8.1-r2-k49) the charge indicator is working fine.

Unfortunately I still cannot use Andorid x86 on my Asus T103HAF because the audio codec is missing.

I know someone succesfully manged to fix this (https://bugzilla.kernel.org/show_bug.cgi?id=115531) but I lack the know-how to recompile te kernel myself, so I can only hope this https://github.com/heikomat/linux/tree/cx2072x/cx2072x_fixes_and_manual/chtcx2072x will included in a standard release…
