Show battery indicator while Cubzh is running

[ahs3n]

Cubzh currently does not show the battery while the app is running. For example on iPhone, there is a lot of empty space at the top to leave space for the dynamic island where the battery (and maybe other stats, like FPS) can fit.

I have also attached an example of another app (Rocket League Sideswipe) which displays its own style of battery and charging indicator, and FPS display.
