I just upgraded Kubuntu 14.04 -> 14.10 and my Apple Wireless keyboard
and Mouse battery indicatores do show up again (command line and KDE
widgets):

Maybe some others can confirm my observation.
Howevver I'm not sure whether it has been a regression in the kernel or an API
change which breaks the user-space applications reading those values. As fas as
I remember I have been booting into 3.16 und 3.17
http://kernel.ubuntu.com/~kernel-ppa/mainline/
from 14.04 LTS and the issue persisted (read: no battery indicator). This makes
me think the reason might be in some ubuntu maintained user-space interface or
other kernel module.
BEFORE upgrading to 14.10 make sure to backup your data / installation! On
Kubuntu I hit into this issue - which completely breaks your system if you
can't help yourself:
